Protection device for decanter centrifuge

With the improvement of China’s electronic technology, the protection device on our decanter centrifuge is more and more perfect, to ensure that the centrifuge is not damaged in various emergencies. Common protection measures are:

1, main bearing temperature alarm

The temperature sensor monitors the temperature of the main bearing in real-time, and when the alarm temperature is set, the buzzer alarms, but does not stop. If no intervention is taken, when the temperature of the main bearing rises to the set maximum temperature, the PLC of the control system will execute the shutdown procedure, which can effectively protect the main bearing to prevent damage to the centrifuge.

2, machine vibration alarm

Through the vibration sensor installed on the rack, real-time monitoring of centrifuge vibration intensity, such as monitoring intensity exceeding the set value, the buzzer on the control panel will alarm, the indicator light flashes and the PLC executes the shutdown procedure.

  1. Overcurrent protection of main and auxiliary motors

There are two ways: one is to use the current relay, according to the maximum bearing capacity of the motor, and give the current relay a setting value in advance, this given setting value range can ensure the good operation of the centrifuge; The other is to detect the current of the main motor and the auxiliary motor through the frequency converter, when the load current exceeds the set value, the alarm and stop to ensure the safety of the centrifuge and personnel.

4, mechanical torque overload protection

When the transmission torque of the differential is overloaded, the rotor connected to the input shaft of the differential will press the lever to rotate, and the other end of the lever is connected with the compression spring, and the compression spring is compressed to the limit position, and the fork rotating with the lever will trigger the limit switch to cut off the power supply of the main motor so that the motor stops running. The device is equipped with a planetary gear differential, which is often used in oil drilling mud separation and other safety and explosion-proof occasions.

The working principle of the mud vibrating screen is used for structural installation, operation and maintenance

The vibrating screen is the key equipment in the solid control system, but also the first level of solid control system processing equipment, its work directly affects the control effect of the whole solid control system. During the drilling process, the drilling fluid with a large number of cuttings is returned from the well, and the role of the shaker is to separate the cuttings from the drilling fluid so that the cleaner drilling fluid enters the later stages of separation equipment.

Working principle of mud vibrating screen

The vibration force generated by the vibration motor drives the sieve bed to make linear, circular, elliptical or translational elliptical motion. The screen will play a role in filtering and screening, screening out solids such as large particles of drill cuttings, and the clean mud with fine particles will fall into the vibrating screen silo to wait for the next level of treatment. The separated large solid particles (usually more than 74 microns) are transported to the outside of the sieve bed under excitation force and discharged to the outside of the tank.

Scope of application of mud shaker

In land and offshore oil and gas drilling/CBM excavation/trenchless directional crossing/piling engineering/waste sewage, mud treatment and other projects, the mud and liquid to be treated for primary or secondary or tertiary solid control treatment. In short, it is the primary treatment of mud and solid-liquid mixtures suitable for various environments.

Factors affecting the performance of mud shaker

Drilling depth, drilling fluid performance, land environment, comprehensive drilling environment/conditions, screen selection, comprehensive performance of the object to be treated, etc.

Structural components of mud shaker

It mainly includes base, frame, screen bed, logging tank, vibration beam, vibration motor, control cabinet, screen box Angle adjustment device, screen mesh, fixed screen mesh device, etc.

Installation instructions for mud shaker

Usually the drilling fluid shaker is mounted on the first mud tank. There will be positioning blocks to help the user identify the location and distance, and the top of the tank where the vibrating screen is located will have openings the size of the sieve bed to receive the treated clean mud. The mud tank should be placed on a flat and clean ground to minimize the influence of the external environment on the performance of the shaker. In the process of transportation or transfer, it is not appropriate to install the screen on the screen box to avoid damage to the screen and affect the use of collision. The transport lock device should always be closed, and the transport lock device should be removed before use after installation to ensure the normal operation of the vibrating screen. During the installation process, read the installation instructions and follow the corresponding restrictions to complete the installation.

Safe operation of mud shakers

Make sure the transport lock is removed before use. It is not possible to repair, move, or even disassemble the motor during the use of the shaker. Follow the safety operation instructions and warning signs on the equipment to operate and maintain the equipment.

Maintenance of mud shaker

  1. According to the safety warning of the vibration motor, the motor should be regularly and reasonably maintained, such as filling lubricating oil;
  2. In the process of use, it is necessary to make careful observation and inspection of the screen. The damaged screen and the completely damaged screen should be repaired or replaced in time;
  3. After each stop using, it is necessary to clean the vibrating screen and screen, so that the screen can have a long life;
  4. Regular and planned inspection and maintenance of the overall situation of the vibrating screen, so that the use of the vibrating screen can achieve the best effect.

5, the use of drilling mud vibrating screen precautions: vibrating screen in the process of use, there may be running or screening blocking phenomenon, then we have to adjust the Angle of the screen box, but should not be too high or low.

  1. Timely observation and monitoring to ensure that the selected screen is suitable for a certain stage of mud. When the vibrating screen does not move according to the predetermined trajectory, there may be a problem with the vibration motor line. For example, if the single motor is running or the installation direction is wrong, the motor or line should be checked at this time to restore it to normal.

Shield dregs dry and wet separation equipment

The so-called dry and wet separation equipment of shield dreg is a set of real-time treatment systems of construction site dreg developed and applied according to local conditions given the limited construction site of the project, which can realize the classification, dehydration, separation, and drying of shield dreg, and reuse of inorganic raw materials and water resources on the construction site.

The dry and wet separation equipment of the shield residue treats 2500-3000 cubic meters of shield material every day, screens the sand and stone in the shield material according to the particle size, and cleans it as far as possible. The remaining mud is dehydrated by the filter press, and the mud cake is loaded without dripping water.

The application of dry and wet separation equipment of shield dreg can rationally coordinate the disposal measures of shield dreg and construction waste, and achieve reduced transportation, environmental protection treatment, and resource utilization, which can not only greatly improve the construction efficiency, but also reduce the safety production risk of the construction site, and promote the “steady, accurate and fast” of shield tunneling and the “accelerated running” of project construction.

Drilling fluid -Shale Shaker use and precautions

A drilling fluid vibrating screen is used for drilling mud solid control equipment, some customers use double or triple-vibrating screens. Drilling fluid vibrating screen has the characteristics of high vibration strength, large screening area, adjustable screen box Angle, compact structure, and so on.

Drilling fluid shaker
How to correctly use a drilling fluid shaker has become a matter of concern for everyone, the following is to share the 6 major drilling fluid shaker use precautions:

1, the correct use of the installation of the power supply, the voltage and frequency of the power supply must meet the requirements of the equipment, generally used in the domestic power supply voltage of 380V, and in some foreign countries the use of electrical system is 460V, so customers are required to confirm the voltage of the power supply, in order to apply the equipment, low pressure may cause the vibration sieve exciting force affected, Shorten the service life of vibration motor in serious cases.

2, the tension degree of the screen should be appropriate, the installation of the screen is also a problem that we should pay attention to, there are wedges on both sides of the screen, which can fix the screen and prevent the screen from falling off in the case of large exciting force, if the tension degree is not appropriate, seriously shorten the service life of the vibrating screen.

3, mesh size must be selected appropriately, under normal circumstances, in the process of oil drilling, one open, two open, three open, four open, one open two open cases of drilling fluid requirements are not very high, users can consider the use of a smaller number of screens, the more the number of screens, the smaller the separated particles, many customers in the choice of screen, Select a smaller number of screens in the early stage, which can help customers save costs.

4, before the use of the vibrating screen, to open the fixing bolt, this is the manufacturer in order to facilitate transportation fixed, to prevent the vibrating screen in the transportation process of shaking, affecting the service life of the equipment.

5, many customers reflect the problem of the vibrating screen running pulp, the main reasons for this problem are several: first, the Angle of the vibrating screen is adjustable and can be adjusted by 1-5 degrees, in the case of confirming that the vibrating screen is flat, the appropriate adjustment of the Angle of the vibrating screen can effectively prevent the problem of running pulp; The second is to correctly match the processing capacity of the vibrating screen, some customers are not very clear about the processing capacity of the vibrating screen, causing the problem of running pulp, so the principle of requiring customers to match is “better than small”; Third, the number of screens also determines the problem of running pulp, the fewer the number of screens, the greater the capacity of the vibrating screen, on the contrary, the smaller the capacity.

6, screen maintenance, the screen is generally matched according to the local rock properties and geological structure, if the match is not suitable, directly shortens the service life of the screen, but also increases the customer’s investment.

“The Benefits of Using a Shale Shaker for Material Separation”

Shale Shakers play a vital role in the oil drilling industry, especially in separating drilling mud from drill cuttings. These devices utilize a variety of vibrating screens, including linear vibrating screens and elliptical dual-track vibrating screens, to effectively remove solids from drilling fluids. Using vibrating screens helps maintain drilling mud properties and reduces the environmental impact of drilling operations.

Linear vibrating screens are often used in vibrating screens to effectively separate solid particles in drilling mud. These screens use linear motion to move drilling mud across the screen surface, allowing smaller particles to pass through while retaining larger particles. This process ensures that the drilling mud is free of debris, which is critical to the overall success of the drilling operation.

In addition to the linear vibrating screen, an elliptical double-track vibrating screen is also used in the vibrating screen to improve the efficiency of the separation process. These vibrating screens feature a dual-motion mechanism that combines linear and elliptical motion to effectively remove solids from drilling mud. Using an elliptical dual-track vibrating screen allows for more complete separation of cuttings, resulting in cleaner drilling mud and improved overall performance.

In addition, mud drying shakers and drilling fluid shakers are integral components of shale shakers and help improve the overall effectiveness of the solids control process. These screens and shakers are used in conjunction with linear shakers and elliptical twin-track shakers to ensure that drilling mud is properly processed and ready for reuse in drilling operations.

Overall, the use of various vibrating screens and vibrating screens in shale vibrating screens, such as linear mud vibrating screens and elliptical dual-track vibrating screens, is crucial for the effective separation of solids from drilling mud. This process not only helps maintain the integrity of the drilling fluid but also minimizes the environmental impact of oil drilling operations. As the oil drilling industry continues to evolve, the importance of shale shakers and their associated shakers and shakers in ensuring the success and sustainability of drilling operations cannot be overstated.

shale shaker: essential equipment in oil drilling operations

In the oil drilling industry, effective separation of drilling mud and solids is critical to the success of drilling operations. This is where vibrating screens come into play as important equipment. A vibrating screen is a shale shaker used to separate drill cuttings and other solid particles from drilling fluids, also known as mud. It is a critical component in the solids control system, responsible for maintaining the quality and consistency of drilling fluids to ensure smooth and efficient drilling operations.

One of the most common types of vibrating screens is the oil drilling mud linear vibrating screen, which uses linear motion to effectively separate solid particles from the drilling fluid. Another variant is the elliptical twin-track vibrating screen, which offers a more efficient and thorough separation process due to its unique elliptical motion. These vibrating screens are designed to handle large volumes of drilling mud and are equipped with multiple screens to ensure the efficient removal of solid particles of different sizes.

Vibrating screens play a vital role in the drilling process, not only to separate solids from the drilling fluid but also to ensure that the drilling fluid can be reused. By removing solid particles, vibrating screens help maintain drilling fluid properties, such as viscosity and density, which are critical to successful drilling operations. In addition, mud drying shakers are used to further process the separated solids, thereby recovering valuable drilling fluids and processing dry solids.

Drilling fluid shakers, including mud linear shakers, are designed to withstand the harsh conditions of an oil drilling site, with exposure to high temperatures, pressures and abrasive materials. Its rugged construction and reliable performance make it an indispensable tool to maintain the efficiency and cost-effectiveness of drilling operations.

In short, vibrating screens are basic equipment in the oil drilling industry and play a vital role in separating solids in drilling fluids. Its various types, such as oil drilling mud linear vibrating screens and elliptical dual track vibrating screens, are designed to remove solid particles efficiently and effectively, contributing to the overall success of drilling operations.

Factors affecting the operation of mud shale shaker

In the oil drilling solid control system, the mud shale shaker belongs to the first level of solid control equipment. The drilling fluid returned from the well through the elevated manifold passes through the shaker first and then enters the other solid control equipment behind for processing. The drilling fluid vibrating screen is filterable solid-liquid separation equipment, but also the solid control system in the first separation and separation efficiency of the equipment, through the vibrating screen can separate and remove a large number of harmful solid phase, effectively cleaning the large particles in the drilling fluid solid phase, then what factors will affect the work efficiency of the vibrating screen, let’s take a look at it.
First, there are many forms of motion of the mud vibrating screen, we commonly use the linear motion of the vibrating screen, linear motion is to put the oscillator in front of the center of gravity of the system above, so that the screen frame produces linear motion, to remove the solid phase compared with other motion trajectory vibrating screen, linear motion vibrating screen has a stable drilling fluid delivery speed, the screen surface is relatively flat, It has high working efficiency, and it can also tilt the screen surface slightly to improve the time of drilling fluid on the screen surface, thereby improving the treatment effect.

Second, the amplitude and frequency of the mud vibrating screen is also one of the important factors affecting the efficiency of the vibrating screen, the vibration frequency of the vibrating screen, the greater the rotation speed, the higher the vibration frequency, the better the effect of screening solid phase; In theory, the larger the amplitude of the vibrating screen, the better the treatment effect, but after the amplitude increases, the greater the force the vibrating screen is subjected to, it will shorten the service life of the vibrating screen, so a reasonable design of the amplitude can improve the working efficiency of the vibrating screen and the service life of the vibrating screen.

Third, the inclination of the mud vibrating screen and the mesh number of the screen is also one of factors affecting the efficiency of the vibrating screen, generally KOSUN single-layer vibrating screen has 2-4 screens, and the front screen is generally flat after a screen has a certain tilt Angle, This is designed so that the drilling fluid can efficiently pass through the front screen and improve the treatment effect when passing through the back screen. The mesh number of the screen is also very important, we are dealing with different materials, and need to achieve different treatment effects, need to choose the appropriate mesh of the screen that can improve the treatment effect and achieve our treatment effect, if the mesh number is too high will reduce our work efficiency, or the mesh number is too low will affect our treatment effect
