1.Pump before starting the pump should be filled with liquid filled with enough water, no liquid starting.
2.Close the outlet valve, switch on the power supply immediately after the inspection of the pump must be in accordance with the steering arrow of
Along with the progress of science and technology, the type of pump is also more and more, the industry is also increasingly broad application, each pump with its unique performance and play its unique role, here we look at how the pipeline centrifugal pu
The speed of the motor is determined, which is related to the speed of the pump and the transmission mode, such as the direct drive, the speed of the two should be equal, such as indirect transmission, both of the rated speed has a certain speed ratio rel
The automatic coupling device of sewage pump is a pump and discharge device matched set, mainly by the submersible pump, automatic coupling device, a water outlet pipe, automatic coupling device is installed between the submersible pump and the water outl
1. Reasons: pump is the power is not complete, small horse cart, motor overload long time operation, the motor temperature is too high; the motor start too often fixed for the short-term or intermittent work system of continuous work. Should limit the num
1.To carefully check the mechanical seal number of parts is not meet the needs of, all kinds of mechanical seal equipment operation, each element is damaged, especially dynamic and static ring has no bumps, cracks, deformation and other defects. If there
1. Water pump surface and pressure water chamber (also known as the spiral case) the surface corrosion. The surface rust embossing will pump water reducing 7%-8%; maintenance only steel and iron brush paper or grinding smooth, you can make it at work to r
Because of the suction and discharge liquid inlet pressure, the impeller on both sides of the impeller is not completely symmetrical, which is not completely symmetrical, thus producing the axial force of the centrifugal pump. If the two sides of the impe
1.Regularly check the pump and motor, the replacement of wearing parts.
2.Always pay attention to the bearing box filling high quality calcium base grease, in order to ensure good lubrication of the bearing.
3.Do not use a long time ", in addition to
1.The pump should be filled before the start of the pump filled with liquid, no liquid starting.
2.Close the outlet valve, after the power is switched on to immediately check the pump must press the pump turn arrow consistent, non reverse operation.
Heat pump is a kind of energy from the nature of the air, water or soil to obtain low grade heat, power equipment after work, high grade heat output can be used. It is a kind of energy conservation and cleaning of the heating and air conditioning equipmen
Submersible sewage pump is a pump and motor connected, and at the same time into the work of the pump liquid products, it is a kind of sewage pump, vane, channel width, can transport all kinds of domestic sewage, industrial waste, construction site draina
Having been prepared for nearly a month, our representatives led by Destiny flew to Hanoi on time the day before. With full preparation and confidence, today on October 17, 2016, Destiny and her partners are witnessing the successful opening of Zhengzhou
1.Horizontal open pump speed is low :
1).Artificial factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.
2).Mechanical failure of the
1.Horizontal in the open pump before the start of the filling is not enough water, sometimes looks like the water has been poured from the vent overflow, but did not turn the pump shaft to the air completely discharged, resulting in a little air left in t
1.Horizontal in the open pump does not water
2.Horizontal open pump speed is low
3.Horizontal open pump suction process is too large
4.the resistance loss in the inlet and outlet pipe of the water inlet and outlet pipe is too large.
The use of non clogging self suction sewage pump is of great significance to the maintenance and maintenance of the pump and the service life of the pump. Again good equipment, if you do not know how to maintain and maintenance, will be scrapped in advanc
1.The end of the valve can not open. Is usually set aside a long time due to water pump, valve gasket is stuck, no washer valve may be rust.
2.Filter mesh bottom valve is blocked; or potential water valve at the end of the sludge layer caused by the blo
Suction is too large :
Some of the water is deep, some of the surrounding terrain is relatively flat, while ignoring the pump allows suction process, resulting in less water absorption or not the result of water suction. To know that the vacuum degree of
