Vertical sewage pump characteristics and maintenance methods

Vertical sewage pump can be moved, but also fixed installation, for the construction, farmland irrigation and drainage, sewage treatment enterprises, processes and pumping, in addition to conveying sewage, but also for the drainage pump, pulp pump, irrigation Use, etc., can also be used for water and weak corrosive media. Now to introduce the characteristics of vertical sewage pump and maintenance methods.

First, the pipeline sewage pump product features

(1) sewage capacity, no congestion.

(2) Reasonable design, matching motor power is small, energy-saving effect is significant.

(3) wear-resistant mechanical seal.

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

(5) to be able to run in the whole range, while ensuring that the motor will not be overloaded.

(6) Inlet and outlet centerline in a straight line, can be installed directly in the pipe anywhere.

Second, sewage pump maintenance and repair

(1) Check the sewage pump pipe and joints with loose phenomenon. Turn the sewage pump by hand and see if the sewage pump is flexible.

(2) Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, lubricating oil should be replaced or replenished promptly.

(3) Unscrew the diversion plug of the sewage pump body, and pour the water (or slurry). Self-priming sewage pump.

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

(5) Move the motor to see if the motor is steered correctly.

(6) start the motor, when the sewage pump is running, open the outlet pressure gauge and inlet vacuum pump as it shows the appropriate pressure, and gradually open the gate valve, while checking the motor load conditions.

(7) try to control the sewage pump flow and head in the range indicated on the sign to ensure that the sewage pump at the highest efficiency point of operation, in order to get the maximum energy saving effect.

(8) sewage pump in operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C.

(9) If it is found that the sewage pump has an abnormal sound, stop immediately to check the cause.

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

(11) Open the pump sewage pump in the first month of work, after 100 hours to replace the oil, after each 500 hours, oil change time.

(12) Often adjust the packing gland to ensure normal drip leakage in the packing room.

(13) Regular inspection of the sleeve wear, wear and tear should be promptly replaced.

(14) When sewage pump is used in winter season, after parking, it is necessary to unscrew the drain plug at the lower part of the pump to release the medium. Prevent cracking.

(15) long-term disabled sewage pump, pump all the necessary open, dry the water, the rotating parts and joints coated with grease installed.

Steel Pipe Lined With Polyethylene Wear Resistant Pipe

Cross helically wound steel wires reinforced-polyethylene composite pipe (SRCP) is a kind of composite metal plastic pipe with excellent overall performance. With excellent pressure bearing performance, good flexibility, long-term resistance to acid and alkaline corrosion and abrasion, it is suitable for long-distance underground pipes for water supply and drainage, slurry transportation and the like, especially for subsidence region such as mining area, river channel.
