Small electric pumps, hydraulic power Lu (certified), an electric pump is provided by the Texas Lu force hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lu Jingli. Cause electric pump unresponsive reason is powered electric pump which is a kind of mechanical equipment, is one of the common devices in various engineering industries. In practice, the construction workers of the electric pump is powered dsd electric pump, there will be no response to the phenomenon. If you're not familiar with the people, might not know the reason. Through comprehensive practice found that the main cause of this type of failure is the power plug, power outlet and motor winding road blocked due. If, after the power is turned on, an electric pump was found difficult to start or can not start, and when accompanied by the hum of the electric pump, we need to overhaul them. Then used a small blade in the direction of running quickly struck fan, if the motor can be up and running quickly, indicating a start winding start capacitor or damaged, replace or repair the same start winding capacitance; if motor issuers, mostly motor and mechanical failure of the pump head appeared, such as bearing damage, impeller stuck and so on. Experts tell what are the advantages of hydraulic electric pump hydraulic electric pump is a perfect combination of a mechanical pump and motor products, is kind of a pump is to be conveyed to the liquid motor mechanical compression electric pump, the liquid energy continue to increase, so as to achieve the purpose of conveying pressurized liquid or liquid, mainly used to transport liquids. Therefore, the electric pump can be used to make car engine fuel booster can also be used for continuous injection of aviation turbojet engines, machinery, etc. can also be used for food on the need for liquid delivery of the electric pump control diaphragm metering pump parts is to control the motor. When using traditional methods to control the phenomenon of trapped oil pump gear speed, you need to install speed devices. Whether you are installing magnetoresistive magnetic sensor, or an electric pump core tachometer, or Hall sensors and other types of sensors, will continue to increase the volume of the motor, the constant increase in the cost of a small electric pump, causing increased fuel electric heat pump core, and motor manufacturing process requirements increase and other issues. Therefore, the experts in the working principle and structure of electric pumps were studied after different from the traditional paper proposes a method for controlling electric pump control system.
