Submerged pump device and a step

long shaft submerged pump can transport medium temperature scale

long shaft submerged pump is a kind of submerged water pump using raw material, at present more popular is the FY type submerged pump, it is a long vertical shaft submerged pump, long shaft submerged pump is in a kind of raw material. Long shaft submerged water pump is widely used in chemical, petrochemical, refining, dyestuff, pesticide, pharmaceutical, rare earth, fertilizer and other industries, transport all kinds of media in the storage tank, the open impeller can be used to transport medium containing solid particles.

submerged water pump device and start

1, the pump foundation should be flat, with level leveling, enough to withstand the weight of the pump and not deformation, the warp and woof of pump and ensure the device design work and parking in the state of small oscillation value, otherwise will be reduced life spans. The weight of the pump discharge line should not be directly on the pump, so as to avoid the pump pressure or bad influence the concentricity. Since the flushing pump, with its own medium scour sliding bearing, pipe has been connected. Wash outside, outside the user needs to take over to the way of flush pipe of pump, external flushing fluid.

2, a long shaft submerged pump outlet pipe valves and check valves, control flow, avoid the reversal.

3, start running acknowledged the following data, motor speed, the pressure gauge is suitable for pump discharge head range, admitted to flush piping valves open, external flushing water supply.

4, check the bearing box should have enough grease, grease for about half of the bearing capacity of cavity, normal once every four months to replace, grease by bearing gland on the nozzle injection.

5, view the rolling direction of the motor is correct, prohibit reversal, wash outside the flush valve open outside.

6, pump to ban idling, put back the clock. In order to avoid light load and overload can owe flow device, over-current protector.

7, pump should be turning 3 - before launch Five laps, flexible rolling without a murmur, feel normal before launch, driving front coil car is necessary. Long shaft submerged pump start it in the outlet valve closed, but should pay attention to when the outlet valve closed work for a long time, can present heating liquid in the pump, when the pump outlet pressure to normal, and then gradually open the outlet valve, pressure calibration and adjustment to the nameplates.
