Since the balance wear-resisting multistage pump repair and maintenance knowledge

self balancing wear-resisting multistage pump repair and maintenance knowledge:

( 1) Check the balanced wear-resisting multistage pump pipe road and the junction have loose phenomenon. Turn the multistage water pump with the hand, and proved the multi-stage pump is flexible.

       ( 2) To join bearing the body bearing lubrication oil, should observe the oil level in oil mark the centerline, lubricating oil should be timely replacement or supplement.

       ( 3) Unscrewed the self-balancing wear-resisting multistage centrifugal pump water pump body of water diversion plug, water perfusion ( Or plasma) 。

       ( 4) Close out of the water gate and export of pipeline pressure gauge and imported vacuum gauge.

       ( 5) Power motor, and proved the motor steering is correct.

       ( 6) Self balancing wear-resisting multistage pump stopped for a long time, the water pump must be opened entirely, dry the water, will turn the parts packed and junction coated with grease.

       ( 7) Try to control the balance of wear-resisting of multistage pump capacity and head, within the scope of the specified on the sign to ensure that the multistage pump running at peak efficiency, to achieve maximum energy saving effect.

       ( 8) in the process of operation, the bearing temperature no more than the environment temperature to 35 c, the highest temperature should not exceed 80 c.

       ( 9) In case of abnormal sound of a multistage centrifugal pump l should immediately stop check.

       ( 10) Self balancing wear-resisting multistage pump to stop using, first close the gate valve, pressure gauge, then stop the motor.

       ( 11) in the first months of work, the oil change 100 hours, every 500 hours, after oil change at a time.

       ( 12) Self balancing wear-resisting multistage pump often adjust the packing gland, packing materials indoor drip situation is normal, In a drip out as appropriate) 。

       ( 13) Regularly check the balance abrasion and multistage pump shaft sleeve, wear after the larger should be replaced in a timely manner.

       ( 14) when used in cold winter season, after the stop, the lower part of pump body must be drain plug unscrewed the net medium. To prevent the frost crack.

       ( 15) To start the motor, after the multistage pump operation, open the outlet pressure gauge and imported vacuum pump after it shows that proper pressure, gradually open the gate valve, check the motor load condition at the same time.

Anyone who has seen the latest winter cover pump submersible pump in operation cannot help but be impressed with how far the technology has progressed over the past few years.
