Dry sieve is used to recycle liquid drilling fluid shale shaker in the well site.

Dry sieve is used to recycle liquid drilling fluid shale shaker in the well site, dry vibrating screen or dry sieve is a kind of linear vibrating screen, in the process of drilling waste management is mainly used for recycling the main vibrating screen and hydrocyclone discharge of drilling cuttings adsorption in liquid phase, the recycling of liquid phase method is especially suitable for oil-based mud, can effectively reduce the waste mud.

Compared with the mainstream drilling fluid vibrating screen, the dry sieve mesh used in the drilling fluid drying screen will be larger. As the cuttings treated by the drying screen are relatively dry, high-frequency vibration motor is generally used as the power source for drying. This allows the recovery of drilling fluid through the screen slowly, coupled with strong vibration force, can maximize the recovery of drilling cuttings in the liquid phase.

Functions of dry sieve treatment system:

1. Reduce the liquid content in cuttings and recover valuable drilling fluid, thus reducing the cost of drilling fluid;

2. Reduce the total discharge of mud cuttings, thus reducing the waste slurry to be treated, so as to meet the requirements of environmental protection.

Application fields of dry sieve treatment system:

1. Dry cuttings for drilling mud of various types, such as oil-base mud, water-base mud and composite base mud;

2. River dredging;

3. Environmental protection solid-liquid separation

4. Piling work;

5. Shield engineering.

Structure features of KOSUN vacuum degasser

During drilling operations, the gas carried by drilling fluid from the well can affect mud performance and safety, and also affect the service life of some equipment. Therefore, it is necessary to install a vacuum degasser to remove the gas concentration in the mud.

Structure features of KOSUN vacuum degasser:

1. Use vacuum pump to pump mud into the vacuum tank, and use it to make gas out of the vacuum tank, vacuum pump plays two different roles here;

2. Water ring vacuum pump is always in isothermal state in the working process, suitable for the suction of inflammable and explosive gases, with reliable safety performance;

3. The mud shoots to the four walls at high speed through the window of the rotor. The bubbles in the mud are completely broken and the degassing effect is good;

4. Main motor bias, lower machine center;

5. Adopt belt transmission to avoid complication of deceleration mechanism;

6. The use of liquid-gas separator will not cause water and gas to be discharged at the same time, so that the exhaust pipe is always unblocked.In addition, it can supply water to vacuum pump circularly, saving water.

7. The suction pipe is inserted into the slurry tank, and can be used as a high-power agitator when the slurry has no gas invasion.

Maintenance of centrifugal pump

There are so many methods for you to make sure a longer service life of centrifugal pump:

1. Before and during operation, the insulation resistance of the motors must be checked regularly, and the grounding condition should be checked to see if the cable skin is broken;

2. Check whether the centrifugal pump line and the joint are loose. Turn the centrifugal pump by hand, check whether the centrifugal pump is flexible;

3. Add bearing lubricating oil into the bearing body. Observe the oil level at the center line of the oil mark;

4. Try to control the flow rate and head of the centrifugal pump within the scope indicated on the label, so as to ensure the operation of the centrifugal pump at the highest efficiency point, in order to obtain the maximum energy saving effect;

5. During the operation of the centrifugal pump, the bearing temperature shall not exceed the ambient temperature of 35℃, and the maximum temperature shall not exceed 80℃;

6. If abnormal sound is found in the centrifugal pump, stop immediately to check the reason;

7. When the centrifugal pump is to stop using, first close the gate valve and pressure gauge, and then stop the motor;

8. The lubricating oil of the centrifugal pump shall be changed for 100 hours within the first month of operation. After that, the oil shall be changed every 500 hours;

9. Often adjust the packing gland to ensure normal drip leakage in the packing room (it is advisable to make drip leakage);

10. Check the wear condition of the shaft sleeve regularly, and replace it in time after big wear. Horizontal centrifugal pump to check the pump coupling regularly, the unit overhaul is generally one year;

11. When the centrifugal pump is in use in the cold winter, after stopping the pump, unscrew the waterproof screw at the bottom of the pump body to clean the medium. Prevent frostbite;

12. When the centrifugal pump is out of use for a long time, all the pumps should be disassembled and wiped dry. The rotating parts and joints should be coated with grease for proper protection;
