Causes of Electric Motor Burning by Water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different. May r...

The advantages of the stainless steel centrifugal pump

The stainless steel  centrifugal water pump  can be used to convey various medium from tap water to industrial liquid at different temperature with different flow and pressure.the stainless steel  centrifugal water pump  can be used to transport the liquid,which PH Value is 5-9,the liquid can be slightly alkaline water,take off a mineral water,distilled water,swimming pool water,chloride liquid, they are anti-corrosion pumps. Stainless steel  centrifugal water pump  can last for a long time, stainless steel gear pump because the high quality material and light weight rotating parts, the stainless steel  centrifugal water pump  life expectancy is much longer than the ordinary pump. Gelaili pump industry ,supply professional stainless steel water pump. www.jxgllpump.com

Difference between suction stroke and lift head of water pump

Pump self-priming capacity is also called maximum self suction height.It is the maximum height at which the water is pumped (the vertical distance between the pump and the the liquid surface to be pumped) without fill in water into the pump tunnel. General water level is lower than the location of the pump, you need to pump self-priming capacity.For example ,if we need to pump water from a river ,we will not plan pipe first,so we need a pump which has self-priming capacity. Or we need to pump some corrosive liquid,we can not fill water into the water pump tunnel. Some centrifugal water pumps do not have self-priming capacity,they need to fill in water at first time of using. The pump lift is the height that pump can lift water up.We usually expressed in H,the the unit is meter. The lift of the centrifugal pump is based on the center line of the impeller.The lift Consists of two parts,first is the vertical height from the center line of the pump impeller to the surface of the water s...
