Product Introduction:
WQ Non-clogging Sewage Submersible Pump Cast Iron Pump is composed of motor, water pump, seal. With volute impeller structure, the water pump is under the single or three phase asynchronous motor. Mechanical seal is used as motive seal between motor and pump, and oil resisting rubber O ring works as the static seal for the rabbet. Because of single or double channel, flow gap is big, then the discharge capacity of the pump is improved.

Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
It burns and seals when idling. The individual thinks that it can be indirectly reacted according to the pressure change in the pipeline, and the electric contact pressure gauge can be installed on the suction pipe
Q:What is the reason that the water supply of pump is getting smaller?
What kind of pump is it, home pump or factory pump? Single stage impeller or multistage impeller? Vertical or horizontal? Is it single suction or double suction? Different structure of the day pump has different causes of failure. But in general, there are several aspects: 1., the water inlet is small, the inlet pipe is blocked; 2., the blade is worn or broken; 3., the motor speed drops; 4., sealing serious leakage; 5., cavitation phenomenon.
Q:How many kinds of pumps are there? What are the advantages of soft start?
Start the pump direct start, soft start and step-down start, starting four, direct start motor is generally suitable for small power, we usually use, at 15kw below the pump price; Step-down start is the star delta conversion is started, start is two times speed to reach the rated speed of the general. Using the above 18.5kw, the pump price moderate; soft start is gradually increased to the rated speed of the pump, the impact is very small, the price is relatively high, generally 3 times the step-down start; is the most advanced frequency conversion start, not only have advantages of soft start, also can be set to work at any speed, there are significant effect on energy saving.
Q:What motor does the pump use?
Hello, the pump is generally used permanent magnet synchronous motor, and if the motor is not too understand, you can consult the motor suppliers, according to the model to choose their own use.
Q:Why can domestic pumps sometimes pump water and sometimes not?
You pump 1. is fully automatic, 2. have small pressure tank 3., stop valve should be 1., tap water is interrupted, 2. water intake, water out of harmony
Q:How large is the starting current for a 1.5 kW submersible pump?
1KW about 2 current, so the rated current is about 3A, and the starting current is usually 3-8 of the rated current, that is 9-24A.
Q:What is the function of a submersible pump?
Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.
Q:What's the water pump?
The make-up water pump is neither a chilled water pump nor a cooling water pump. It is a water pump for the water supply of the chilled water system.
Q:What are the quota items for the complete pump installation?
Pump installation / anchor bolt installation anchor bolt hole, fill oar vibration cushion installation
Q:(flood control emergency plan) what type of water pump should be used for flood control? How to choose
Select the QW submersible pump, which is potential water, (flow, lift, bore, power)Flow, how many tons of water pump an hour to play, you choose how much?Lift, water pump from the destination is a few meters, how many meters?,Caliber, this pump potential water, without flange connection, only flow, head can reach.Power, look at the flow and lift is how much, and then choose the right motor (this is regular)The voltage is usually 380V.You can move, it is best to fix a seat, weight, this pump is basically a person can not move, and small can take.Brand, regular manufacturers can.Model, (caliber, flow, lift, power, voltage) tell the manufacturer.
