First, the submersible pump in the pump suction pipe set on the vacuum pump, pump start before the start of the vacuum pump, so that the first water pump filled with water to ensure that the pump automatically and quickly start. This type of water absorption requires a sound automatic control system to ensure proper operation.
Second, relative to the following are also relatively simple: no clogging submersible pump to reduce the water pipe corners, drop height and horizontal interval.
Third, this way need to set up a suction pipe in the pump, the pump in the first run before the tank should be filled with water, the first run after the end of the water tank due to the height of the water pipe height , Although the water level in the pool below the tank surface height, the tank of water will not turn back.
The last way to install the suction end valve at the end of the suction pipe of the submersible pump. The suction valve is actually a check valve, which ensures that the water can only enter the suction pipe from the pool and can not be reversed, so if the suction pipe is filled with water, although the pump axis elevation is higher than the working water level of the pool. The role of the end of the valve, the water pipe will not flow into the pool, the suction pipe has been filled with water, to ensure that the pump can automatically and quickly start.
Sewage pump is a common device for us, have brought some impact to our lives, sewage pump manufacturers in order to let everyone maintain it better, it is necessary to understand its exhaust treatment measures.
1.It is necessary to have a pre-pump when use sewage pump, use the pre-pump to make the system pressure be a certain range, then start the sewage pump. So you can avoid the sewage pump overload, the former pump can choose water ring vacuum pump, Rotary vane vacuum pump, slide valve vacuum pump, reciprocating vacuum pump can be the atmosphere of the vacuum pump.
2.For higher occasions, the sewage pump can not be straight into the atmosphere. The front of the atmosphere will constitute the sewage pump suction port and exhaust pressure difference is too large, so that the sewage pump overload. To ensure that sewage pump can reach a higher vacuum, it is necessary to be sure that the sewage pump has open space between the rotor.
3.Due to the continuous rotation of the rotor, the suction gas from the inlet into the rotor and the pump shell between the space, and then discharged through the exhaust. As the inspiratory space is fully closed, so the gas in the pump chamber is not tightening and swelling. However, when the top of the rotor turns through the edge of the exhaust port, when the v0 space communicates with the exhaust side, a part of the gas flows back to the space v0 to increase the gas pressure. When the rotor continues to change, the gas is drained outside the pump.
Nanjing lanshen Pump Corp.LTD. warm reminder: when sewage pump in use, it must be normal exhaust, otherwise the gas exists in the pump will affect the entire machine, serious will lead to the whole machine paralyzed.
