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;

The SP shear pump produced by KOSUN can quickly prepare high-performance slurry.

The SP shear pump produced by KOSUN can quickly prepare high-performance slurry, greatly shorten the preparation time of slurry, and improve the economic benefits of drilling.

Shear pump is a machine specially designed for shearing polymers and clays and has been used in the field and proved effective in theory. In the drilling fluid system, polymer (or clay) should be sufficiently in advance after shearing, again into the drilling fluid system, in order to give full play to its functions, improving drilling fluid performance, if there is no sufficient shear, polymer in the first cycle could jam vibrating screen mesh, lose a massive amount of polymer, to increase the drilling cost, and may also make the large size of solid phased particles in drilling fluid hard and difficult to get rid of; In drilling fluids, the polymer produces many “fish-eyes” due to insufficient shear. These “fish eyes” can harm the formation, reducing permeability and reducing oil and gas production.

The shear pump provides a high degree of shear for rapid hydration of polymers (or clays) and resolves prominent problems with poorly hydrated polymers (or clays) in drilling fluids. At the same time, the use of shear pump can make the polymer injection amount reduced by more than 15%, the dosage of bentonite reduced by more than 30%, and improve the mud cake and fluid flow loss, reduce drilling fluid shear rate, improve the gel strength, has reached the advanced level of similar foreign products, the shaft seal structure is more reliable, excellent performance, the use of maintenance more convenient.

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.
