WQK/QG submersible sewage pump use range and precautions

WQK/QG submersible sewage pump use range

WQK/QG belt cutting device sewage pump is mainly used for engineering sewage and domestic sewage. Such as:

(1) Used in construction sites, engineering foundation construction, municipal facilities, and waterworks.

(2) Sewage discharge from underground floors such as basements, civil air pits and subways of various high-rise buildings.

(3) Sewage treatment and circulating water transportation for small and medium-sized enterprises.

(4) Slurry slurry pumping from factories and mines such as food, paper, brewing, steel and non-ferrous metals, leather, textile, pharmaceutical, and cement plants.

(5) Chicken farms, pig farms, various aquaculture industries, fish ponds for pumping clear ponds, aeration, septic tanks, etc.

Note: The main performance and data of WQK are the same as WQK/QG except that there is no cutting device.

WQK/QG submersible sewage pump use precautions

(1) Before using the electric pump, first check whether the cable is damaged. When the water pump is moved and installed, the iron is pulled or the cable is damaged to avoid the water leakage and the accident. If the cable is hardened, replace the cable immediately. And check the insulation resistance of the electric pump with a megohmmeter (insulation resistance must not be less than 1 megohm)

(2) Make sure that the grounding wire (the ground wire is generally yellow or green or with a grounding mark), and connect the ground wire according to the prescribed procedure. (The grounding wire of our factory is equipped with a grounding mark).

(3) Select a suitable protector (such as leakage protector, air switch, phase-breaking overcurrent protector, etc.) Do not connect directly with the knife switch.

(4) Connect the power cable according to the standard, test the power supply, check whether the electric pump is running normally, and judge whether the steering is correct. If the steering is not correct, replace any two of the three power cables. The time cannot exceed half a minute).

(5) Install the water outlet joint and the water outlet hose (or iron pipe), and fasten the rope on the electric pump handle (must not use the cable instead of the sling). Put the electric pump into the pumped liquid and connect it. Power, ready to use.

(6) In order to ensure personal safety, it is strictly forbidden to install the sewage operation (such as moving or checking, troubleshooting, etc.) in the vicinity of the electric pump during the power-on work of the electric pump to contact the electric pump to prevent accidents caused by electric leakage of the electric pump!

(7) It is forbidden to expose the water pump to the water surface for a long time (or short-time operation). The “on” and “stop” of the electric pump should not be excessively frequent to prevent the motor from overheating and damage.

(8) Long-term pumping of high-sand liquids will cause excessive wear on the over-flow components of the WQK/QG belt cutting device. It is recommended to use the cyclone sewage sewage submersible pump products.

(9) If it is found that the WQK/QG belt cutting device sewage pump is running, there is abnormal phenomenon such as non-rotation, protector tripping, fuse blown, etc., immediately cut off the power supply, check the power protector wiring, etc. whether there is a problem. If these external devices are normal, it may be that the electric pump is faulty. At this time, it should not be used to avoid accidents!

Axial Flow Pump

Permanent magnet synchronous motor axial flow pump is a new advanced application of permanent magnet synchronous motor in the field of pump. It has the characteristics of high efficiency, light weight, small volume (only 1 / 4 of the weight of traditional axial flow pump), large flow and convenient movement. Stepless speed regulation, head and flow can be adjusted by adjusting speed.


At the same time, another characteristic of permanent magnet synchronous motor is that the speed does not change with the grid voltage. When the voltage changes, especially when the voltage is low, it can still keep the head flow unchanged, which is not available in the traditional axial flow pump of asynchronous motor.
