KOSUN desilter is used in solid phase control system of drilling fluid.

The desilter is mainly composed of shale shaker, shunt manifold, hydrocyclone, etc. The desilter is used in solid phase control system of drilling fluid.

Desilter is designed according to the principle of particle sedimentation, the drilling fluid separation medium through sand pump produce certain pressure and velocity, along the spiral into the cyclone wall, coarser particles under the action of centrifugal force and gravity, the hydrocyclone wall spiral sink, discharge from the bottom orifice, falls below breakdown vibrating screen separation, the rest of the medium has risen in a spiral along the hydrocyclone.

Installation and debugging:

1. The desilter cleaner shall be installed after the desilter cleaner, i.e. the end of the second tank, and the base shall be placed smoothly;

2. Soft pipeline is used to connect the inlet and outlet of the desilter with other equipment, and the length and bend are reduced as much as possible;

3. The tension of the sieve mesh should be appropriate, the tension of the sieve mesh should be flat without wrinkles.

Maintenance of the desilter:

1. The lock bolts of the sieve box must be removed before the first use of the newly purchased desilter cleaner or the first use after the move;

2. When the hydrocyclone is out of use for a long time, clean it with clean water to prevent the accumulation of dry sand in the hydrocyclone;

3. The vibration motor is injected with grease once every 1500-2500 hours, and the oil injection amount of each bearing is 5-10ml;

4. After stopping the machine, the screen should be cleaned, so as to avoid dry sand, which cannot be used next time.

KOSUN vibration screen’s preparation before installation and daily maintenance

KOSUN vibration screen, divided into two types: elliptical motion shale shaker and linear motion shale shaker.

KOSUN elliptical motion shale shaker‘s elliptical movement, is a multi-layer number, efficient new type of shale shaker. Screening specifications, with a reliable structure, strong vibration force, high screening efficiency, small vibration noise, rugged, easy maintenance, safe use and other characteristics, this type of vibration screen is widely used in mining, building materials, transportation, energy, chemical industry, coal, metallurgy and other industries product classification. Strong processing capacity, high screening efficiency, reasonable technical parameters, high strength and stiffness of the mechanism, reliable operation, low noise, easy maintenance and other characteristics.

Preparation of the elliptical motion shale shaker before installation:

1. Check whether the motor label conforms to requirements;

2. Check the fasteners of the motor to prevent loosening;

3. Check whether the motor surface is damaged or deformed;

4. Check whether the rotation is flexible; if there is any abnormality, it should be excluded;

5. Check the power supply for lack of phase and run for 5 minutes without load.

Daily maintenance of theelliptical motion shale shaker:

1. Before starting: check whether the coarse mesh and fine mesh are damaged; Whether each group of beam rings is locked.

2. During starting: pay attention to whether there is any abnormal noise; Whether the current is stable; The vibrations are indistinguishable

3. After use: clean up immediately after each use.

4. Regular maintenance: check the fatigue and damage of coarse mesh, fine mesh and spring regularly, and check whether all parts of the shale shaker are damaged due to vibration. Lubricating oil must be added to the parts that need lubricating oil.

KOSUN’s submersible slurry pump

Although KOSUN submersible slurry pump is widely used, its correct application is very important. Due to the limitations of its name, some non-industry people have a misunderstanding of this, in the application process of submersible slurry pump, we must pay attention to the reasonable design, correct calculation, appropriate selection, these points are very important.

Installation of the submersible slurry pump:

1. Preparation before installation: check whether the water pump and motor are damaged; Prepare tools and lifting equipment; Check the basics by drawing

2. Install the support seat of the pump on the container and tighten it with bolts (for cement well tank, anchor bolts should be set in advance).

Operation of the submersible slurry pump:

1. Note that the pump bearing temperature should not exceed 35 degrees outside temperature, but the highest temperature should not be greater than 75 degrees;

2. The oil cup shall be filled with calcium-based butter to ensure normal lubrication of the bearing;

3. Replace the butter in the oil cup of motor support within the first month of operation or after running for 100 hours, and replace it every 2,000 hours after operation;

4. Check the elastic coupling regularly and pay attention to the heating of motor bearing;

5. During the submersible slurry pump‘s operation, if noise or unusual sound is found, stop immediately for inspection;

6. Every 2000 hours of pump work should be checked periodically. The wear of the clearance between impeller and pump body should not be too large. 7. When the submersible slurry pump works for 6 hours, the machine seal should be checked and repaired or replaced according to the degree of wear, otherwise the pump shaft and bearing will be damaged.
