Centrifugal sewage pump operating specifications

Centrifugal sewage pump, as its name implies, is a pump that combines the advantages of centrifugal pumps and sewage pumps to create a wide range of applications in water treatment, mining, municipal engineering and other projects. Centrifugal sewage pump operation As we all know, centrifugal pump is characterized by not easy to plug, easy maintenance, and sewage pump is not easy to oxidation, safety measures and reliable. These two advantages together, we can effectively block the sewage pump and other issues, can be said to be a very good combination. That for this combination, how to use it? 1, Start 1) Check the bearing box has been refueled, the oil level is normal oil level line. 2) Check whether the direction of rotation of the motor is consistent with the direction of rotation of the pump. 3) Close the spit valve and pressure gauge cock plug, while the top of the screw through the pump body, to the pump suction pipe irrigation. 4) Start the motor and open the pressure gauge cock. 5) When the water pump reaches the normal speed, when the pressure gauge shows the corresponding pressure, open the vacuum gauge cock and gradually open the gate valve on the drain pipe until it is needed. 2, stop 1) first slowly close the outlet pipe gate valve, and then cut off the power. 2) In case of freezing season, shut down, open the lower part of the pump body of the four-way plug, drain the water to avoid cracking. 3) If not for a long time, the parts should be removed and wiped clean, and the sliding surface coated with anti-rust oil, properly preserved. 3, Operation 1) During the operation of the pump, attention must be paid to the observation instruments, bearing fever, packing leakage and pump vibration, noise and other conditions are normal, such as found abnormalities should be promptly addressed. 2) The maximum bearing temperature shall not exceed 75 ℃. 3) Bearing oil should be maintained at the normal oil level, not too high or too low, too low should be refueled. 4) Seal ring and impeller with the gap, greater than the following values ​​should be replaced with a new seal ring. When the diameter of the suction nozzle ≤100mm, the diameter of the total clearance ≥1.5mm when the suction nozzle diameter> 100mm, the total diameter of the microphone ≥2mm (Editor: Cloud QQ:) Recommended reading: Will sewage pump structure
