Use and maintenance method of KOSUN SP series shear pump.

Oil drilling fluid (mud) is mainly composed of four parts: water, active solid phase, inert solid phase and chemical treatment agent. According to the proportion and interaction of each component, different components and different properties of mud can be formed. Therefore, mud composition is the key factor to adjust the performance.

In the preparation and treatment of mud, the traditional preparation method is difficult to achieve the high shear force required for direct hydration of soil and polymer, so it requires a long preparation and treatment time. The SP shear pump developed by KOSUN can quickly prepare high performance mud, greatly shorten the preparation time of mud and improve the economic benefit of drilling.

Use and maintenance method of KOSUN SP series shear pump:

1. After each use, circulate the pipeline and shear pump with clean water to avoid debris blocking the flow path and nozzle of the impeller;

2. Check the machine oil level of the oil pool in the support before use. If it is insufficient, it should be replenished.

3 packing box packing and mechanical seal two.When the seal fails, it should be replaced in time.

4. When using the mechanical seal, it is strictly forbidden not to empty the liquid, so as to avoid damage to the mechanical seal. When the lubricating and cooling oil of the mechanical seal is insufficient, it should be timely supplemented.

KOSUN Vacuum degasser is a kind of special degasser for treating gas-immersed drilling fluid.

KOSUN Vacuum degasser is a kind of special degasser for treating gas-immersed drilling fluid, and its degasser rate is up to 95%, which is suitable for all kinds of oil drilling solid control system. It plays an important role in restoring mud proportion, stabilizing mud viscosity and reducing drilling cost. At the same time, it can also be used as high power agitator.

KOSUN vacuum degasser used vacuum suction effect, cause negative pressure zone in a vacuum tank, mud under the action of atmospheric pressure, through the suction pipe into the hollow shaft of rotor, again by the window around the hollow shaft, the jet shaped into the tank wall, round due to the collision and separation effect, make the separation of drilling fluid into thin layer, immersed in the mud bubbles, gas evolution, through hollow pump suction and the separation of gas water separator, the exhaust pipe line to the safety of gas by the separator, the mud by the impeller discharge outside the tank. Since the main motor starts first and the impeller connected to the motor rotates at high speed, the mud can only enter the tank from the suction pipe, but not from the drainage pipe.

Operation rules of KOSUN vacuum degasser:

1. The installation of vacuum degasser requires smooth connection and reliable fastening, and the exhaust outlet is connected to the safe position outside the wellsite according to the well control requirements;

2. Before the vacuum degasser starts, the end of the drain pipe and suction pipe should be immersed in the mud at the same time, otherwise it will not work normally;

3. After the vacuum degasser is started, check the rotation direction of the motor, which should be consistent with the direction indicated by the arrow on the tank and pump. The water in the pump and the air-water separator must be drained;

How Kosun’s vibrating screen works

When the vibrating screen works, the synchronous reverse rotation of the two motors makes the exciter generate reverse excitation force, forcing the screen body to drive the screen to do longitudinal movement, so that the materials on it are subject to excitation force and periodically throw a range forward, so as to complete the material screening operation.It is suitable for the screening of sand and stone in quarry, and can also be used for product classification in coal dressing, mineral dressing, building materials, electric power and chemical industry.

The working part of the vibrating screen is fixed, the material slides along the working face to screen the material.Fixed mesh screen is one of the most widely used in mineral processing plants. It is usually used for pre-screening before coarse crushing or medium-crushing.It has simple structure and convenient manufacture.Without power consumption, the ore can be directly discharged to the screen surface.The main disadvantages are low productivity, screening efficiency, generally only 50-60%.

Vibration screen working face is composed of a transverse arrangement of a rolling shaft which has a plate, fine particle material from the roller or the gap between the plate through.Large blocks of material are driven by rollers to a section and discharged from the end.This screen is seldom used in concentrating mills.Vibratory screen is cylinder-shaped, the whole screen around the axis of the cylinder mixed rotation, the axis in general is installed at a small Angle.The material is fed from one section of the cylinder, the fine grade material passes through the screen hole on the cylinder surface, and the coarse material is discharged from the other end of the cylinder.The rotating speed of the cylinder is very low, the work is stable and the power balance is good.But its screen hole is easy to block, screening efficiency is low, small working area, low productivity.Concentrating mills rarely use it as a screening device.The collective vibrating screen is a plane shaking or vibrating.It can be divided into linear motion, circular motion, elliptical motion and complex motion.shaking and vibrating screens fall into this category.When the vibrating screen is working, the two motors are placed in opposite positions synchronously so that the exciter generates reverse excitation force, forcing the screen body to drive the screen to do longitudinal movement, so that the materials on it are subject to excitation force and periodically throw a range forward, thus completing the material screening operation.Shaking screen is a crank linkage as the transmission parts.The motor rotates the eccentric shaft through the belt and pulley, and makes the body reciprocate in a certain direction by connecting rod.

The movement direction of the body is perpendicular to the center line of the support rod or suspension rod. Due to the swinging movement of the body, the materials on the screen surface move towards the discharging end at a certain speed, and the materials are screened at the same time.Compared with the above kinds of shaker, the productivity and screening efficiency of shaker are higher.Its disadvantage is poor dynamic balance.It is now rarely used in concentrating mills and it is replaced by more reasonably structured shakers.
