Sewage pump maintenance

(1) check whether there is any loose phenomenon on sewage pump pipe road and the junction. Turn the sewage pump with the hand, and proved the sewage pump is flexible.

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

(3) unscrewing sewage pump pump body of water diversion plug, water perfusion (or plasma). Self-priming sewage pump

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

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

(6) to start the motor, after the sewage 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.

(7) to control the capacity and head of the sewage pump, within the scope of the specified on the sign to ensure sewage pump running at peak efficiency, in order to achieve maximum energy saving effect.

Sewage pump (8) in the process of operation, bearing temperature cannot exceed ambient temperature 35 ℃, the highest temperature should not exceed 80 ℃.

(9) in case of abnormal sound of a sewage pump should immediately stop check.

(10) sewage pump to stop using, first close the gate valve, pressure gauge, then stop the motor.

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

(12) often adjust the packing gland, packing materials indoor drip situation is normal (in a drip out as appropriate).

(13) regularly check the wear condition of shaft sleeve, wear after the larger should be replaced in a timely manner.

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

(15) sewage pump stopped for a long time, the pump must be opened entirely, dry the water, will turn the parts packed and junction coated with grease.
