Product Description:

QW type submersible sewage pump is developed based on imported advanced technology abroad.It has the advantages of high efficiency,not easy to enlace,no clogging,auto-coupling and auto-control

The advantages of QW pump are its small volume,compact structure and high efficiency,with products more than 15kW.It can detect the water leakage,overheat,overload protection.And as the requirements of user,an auto-protection control cabinet which has liquid level control shall be equipped.

Installation type of QW type pump has auto-coupling installation and movable installation.

QWN type submersible sewage pump is developed based on QW type pump,absorbing advanced technology abroad.

Application Area

QW type pump is mainly used in urban construction,industry,hospital,building,hotel,restaurant and so on.It is used to transport silt,urban sewage containing solid granule and long fiber.

QWN type pump is mainly applied in municipal engineering,steel plant,power plant,mines and some other wear-resistant sites for discharging sludge and waster water containing solid particles.

Q:The working principle of magnetic pump
Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.
Q:Metering pumps related matters
1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
Q:Does vacuum pump oil belong to dangerous goods?
Absolutely not. We often send oil by express or by freight. There are no problems at all. Don't be afraid, don't burn, explode
Q:Must the water pump in the tank be all soaked in water?
Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.
Q:Concrete pump 125 pipe wall thickness
Currently mainly divided into gate valve, concrete pump and S valve concrete pump. Another is a pump consisting of a pump body mounted on an automobile chassis and fitted with retractable or bent cloth poles
Q:What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?
SK vacuum pump is a single-stage water ring vacuum pump, vacuum pump and motor separation, coupled with couplings, vacuum relatively low.
Q:Pump operator's responsibility Sharing the rules, responsibilities, etc..
7., master the knowledge of concrete mix ratio, strictly forbid to add water to the pump at will.8., concrete mixing and workability, gravel diameter is too large, effectively refuse to pump.9. when the delivery pump fails, it can analyze the cause and quickly eliminate the trouble.10. pump complete, you must clean the pump body and pressure pipe residual.11. complete other temporary work assigned by the leader.
Q:Water pump dead center lift
The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
Q:What is a gear pump for?
Internal wear of oil pumpOil pump parts wear will cause leakage. The large leakage area between the floating axle sleeve and the end face of the gear is the main part of the inner leakage. This part of the leakage accounted for about 50%~70% of the total leakage. The pump efficiency of the gear pump is much lower than the input power when the gear pump is worn and leaked. All of its losses are converted to heat energy, which will lead to overheating of the oil pump. If the joint plane is pressed, the movement of the floating axle sleeve will cause a little wear and tear when the work is in use, so that the farm tools can be lifted slowly or can not be improved, so the floating axle sleeves must be replaced or repaired.
Q:What is the cause of the damage of pump bearings?
First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.
