Characteristics and maintenance of vertical sewage pump

 Vertical sewage pump can be moved, can also be fixed for the construction, irrigation and drainage, enterprises and institutions in the process of sewage, pumping and transportation, in addition to the application of sewage, but also for the hydrophobic pump, pulp pump, irrigation With, can also be used for water and weak corrosive media. Now to introduce the characteristics of the vertical sewage pump and maintenance methods.

 

First, the pipeline sewage pump product characteristics

 

(1) sewage capacity, no clogging.

 

(2) the design is reasonable, supporting the motor power is small, energy-saving effect is remarkable.

 

(3) the use of wear-resistant mechanical seal.

 

(4) compact, easy to move, easy to install, no need to build the pump house, reduce project cost.

 

(5) can run in the whole head range, and ensure that the motor is not overloaded.

 

(6) inlet and outlet center line in a straight line, can be installed directly in the pipeline anywhere.

 

Second, the sewage pump maintenance and repair

 

(1) check the sewage pump piping and the junction with or without loosening. Turn the sewage pump by hand, see whether the sewage pump is flexible.

 

(2) to the bearing body by adding bearing lubricating oil, observe the oil level should be at the center of the oil standard, the oil should be replaced or added.

 

(3) unscrew the sewage pump pump body water plug, irrigation diversion (or cited pulp). Self - priming sewage pump.

 

(4) close the outlet valve and outlet pressure gauge and import vacuum gauge.

 

(5) Jog motor, see whether the motor steering is correct.

 

(6) start the motor, when the normal operation of the sewage pump, open the outlet pressure gauge and the import of vacuum pumps, as they show the appropriate pressure, and gradually open the gate valve, and check the motor load.

 

(7) try to control the flow of sewage pump and head in the range specified on the plate to ensure that the sewage pump in the highest efficiency point of operation, in order to obtain the greatest energy saving effect.

 

(8) sewage pump during operation, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature of not more than 80C.

 

(9) If there is abnormal sound of sewage pump should immediately stop to check the cause.

 

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

 

(11) in the open pump sewage pump in the first month of work, after 100 hours of replacement of lubricating oil, after each 500 hours, oil change time.

 

(12) often adjust the packing gland, packing room to ensure that the normal drip (in order to drip out into the appropriate).

 

(13) periodic inspection sleeve wear, wear should be replaced after a large.

 

(14) sewage pump used in the winter season, after parking, need to pump the lower part of the water plug screwed open the media release the net. To prevent cracking.

 

(15) long-term suspension of sewage pumps, pumps need to open all, dry the water, the rotating parts and joints coated with grease installed.
