IMO agent Screw pump Is a common fluid conveying equipment, widely used in the industry. How to properly maintain the screw pump is very important for users to ensure its long-term stability and efficiency and prevent failures. Now let's learn about the precautions and maintenance requirements of the screw pump.

1、 Precautions for screw pump

(1) Pre use inspection

Before using the screw pump, it must be checked and cleaned. During the inspection, the sundries and deposits in the oil seal, shaft sleeve, support bearing and other parts shall be removed to ensure that the pump is clean and free of foreign matters.

(2) No reverse

IMO screw pump During the use of the pump, it is forbidden to reverse, otherwise it will lead to problems such as wrong clearance of the pump rotor, mismatch of the pump casing, etc., which will affect the normal working efficiency of the pump.

(3) Prevent excessive operation

During the use of the screw pump, attention should also be paid to prevent excessive operation, to avoid overheating, abnormal noise, pump shell deformation and other abnormal conditions caused by excessive operation.

(4) Keep the lubricating oil normal

When using the screw pump, it is necessary to maintain an appropriate amount of lubricating oil to ensure the normal lubrication performance of the rotor, bearing, etc., and prevent noise and poor operation.

(5) Applicable to multiple media

The screw pump can be used for different media, but it needs to follow up the change of media properties to ensure that the media will not cause damage or blockage of the pump. And when using different media, pay attention to replacing the appropriate seal ring.

2、 Maintenance requirements of screw pump

(1) Refueling and changing oil

The screw pump needs to add proper lubricating oil and replace oil regularly to ensure that the oil is clean and the lubrication effect is normal, reduce the friction coefficient of the pump, and reduce the noise and heat generated during operation.

(2) Clean pump body and accessories

ALLWEILER screw pump Some dirt will be attached during use, which will affect the pump performance. Therefore, the pump body and accessories need to be cleaned regularly to ensure excellent performance.

(3) Maintenance fasteners

The fasteners of the screw pump, such as bolts and nuts, need to be checked regularly to ensure that the fasteners of the body, base and even the infusion pipeline are properly tightened. There shall be neither over tightening nor over loosening.

(4) Maintenance of pump shaft and bearing

The bearing of the screw pump is the central component of the pump. Check the state of the bearing before use to ensure its normal operation. If the bearing is found to be worn, it should be replaced in time to avoid unstable operation and high noise.

(5) Check seals

The pump pressure represents the working pressure generated at the outlet side of the pump, which does not represent the real pressure in the pump, because there will be leakage loss when the pump is running. Therefore, it is particularly important to ensure the sealing performance of the pump.

In short, correct maintenance is essential for the normal operation of the screw pump. Timely finding and solving problems can extend the service life of the screw pump, reduce the maintenance workload and repair costs, and reduce the production downtime and repair costs caused by failures.
