What is the reason why the temperature rise of the motor and variable vane pump of the hydraulic sta

Shanghai Sunshine Pump Manufacturing Co., Ltd. is located in Jinshan Industrial Park, Shanghai, which is a well-known large-scale diversified enterprise integrating research, development, production, sales and service in China, with a registered capital of 80 million yuan. The leading products include: screw pumps, diaphragm pumps, submersible pumps, magnetic pumps, sewage pumps, chemical pumps, multistage pumps, self-priming pumps, gear oil pumps, metering pumps, sanitary pumps, vacuum pumps, submersible pumps, rotary lobe pumps and other categories.

The products have been recognized by various professional certifications and customers with superior performance and excellent quality. The company has a number of pump experts and all kinds of senior engineers, continuous development and manufacturing, upgraded products have come out every year. A rotary lobe pump is a mechanical device that uses a rotating rotor to transport liquids, and its working principle is mainly through the relative motion between the rotor and the pump casing....

Generally speaking, the high temperature rise of the system is caused by the small volume of the fuel tankEnlarge the fuel tank by 2Reduce system flow and system pressure, 3

Forced cooling, such as radiators. 4.If the adjustment of the variable vane pump in the system is unreasonable, the system will not work at the ideal set value, and the variable pressure starting point of the vane pump will be adjusted.

The motor overheats for one reason, overload. When the pressure is high, the motor is overloaded. Either change to a larger motor, or reduce the pressure.

It should be that the pressure of the oil pump is too high and the motor power is not enough1!

1.Reasons for the working environment: the motor winding is attached to the winding by moisture or dust, oil, etc., resulting in reduced insulation.

The insulation resistance of the motor should be measured and cleaned and dried; The ambient temperature is too high. When the ambient temperature exceeds 35, the high inlet air temperature will make the temperature of the motor too high, and the working environment should be improved. Such as building a canopy for shade, etc.

2、.The reason for the motor itself: the wrong connection, the shape is mistakenly connected into a Y shape, so that the temperature of the motor rises rapidly; The stator winding has a phase-to-turn short circuit, an inter-turn short circuit or partial grounding, and the motor is partially overheated when it is light, and the insulation is burned out in serious cases; The rotor of the squirrel cage is broken or defective, the motor runs for 1 to 2 hours, and the temperature of the iron core rises rapidly; If the ventilation system fails, check whether the fan is damaged, whether the rotation direction is correct, and whether the ventilation hole is blocked; The bearing wear and the eccentric sweeping of the rotor make the stator and rotor cores rub against each other and make a metal impact sound, the temperature of the iron core rises rapidly, and the motor smokes and even burns the coil in serious cases.
