Countermeasures for high temperature of vacuum pump The motor power and speed are matched with the imported vacuum pump and cannot be changed. The fan is installed on the main shaft of the motor. The speed of the motor determines the speed of the fan and cannot be replaced. Although increasing the number of fan blades can play a certain role, but the dynamic balance is not easy to find after the number of blades is increased. If the alignment is not good, the motor vibration will increase.(1) The fan cover of the original vacuum pump was lengthened by 40cm, and an axial fan with the same diameter as the fan cover was installed inside. The motor power of the axial fan was 850W, the speed was 1489r / min, and the voltage was 380V. The original fan remains. The axial flow fan is equipped with another power supply control, and the axial flow fan is not interlocked with the main motor. Start the axial flow fan in time after starting the imported vacuum pump, and stop the axial flow fan 30 minutes after the vacuum pump stops, so as to make the main motor fully cooled.(2) Regularly remove the dust on the vacuum pump motor, keep the motor heat sink clean and increase its heat dissipation capacity.(3) Adjust the bus voltage of the imported vacuum pump to 400V.

What is the discharge pressure of liquid ring vacuum pump Liquid ring vacuum pump is used in many industries, so we have a lot of knowledge to know about it. I don't know how much you know about its exhaust pressure, but this article analyzes and introduces the exhaust pressure of liquid ring vacuum pump for you.The exhaust pressure has a great influence on the suction capacity and shaft power consumption of liquid ring vacuum pump. When it is running, if the exhaust pressure is higher, the suction volume will be smaller, and the power consumption of the corresponding shaft will be greater. On the contrary, when the exhaust pressure of the system is smaller, the suction capacity will be greater, and the power consumption of the corresponding shaft will be smaller.Therefore, in the actual operation and maintenance process, the exhaust pressure data should be observed in real time. When there is abnormal exhaust pressure data, corresponding measures should be taken immediately to update and transform the whole vacuum system, so that the exhaust pressure of the vacuum system can be maintained in the range of national standards or recommended by manufacturers for a long time, so as to ensure that it is always in better working conditions and effectively improve the liquid ring The overall operation mechanical efficiency of vacuum pump.Through the introduction above, we understand that the exhaust pressure is also another major factor affecting the operation efficiency of liquid ring vacuum pump, so we need to know more about this knowledge.

Skill of vacuum pump oil filtration and replacement After the dust, impurities and contaminated oil sink into the bottom of the main oil tank, they flow into the auxiliary oil tank through the oil return pipe. After separation and precipitation, the emulsified oil, water, dust and impurities sink into the bottom of the auxiliary oil tank and are discharged regularly by the discharge valve. The relatively clean oil is filtered by the filter in the upper part of the auxiliary oil tank, and then enters the oil separation chamber through the oil inlet pipe, and then supplies to the end cover and pump chamber.During the use of vacuum pump oil, due to oxidation, emulsification and various impurities mixed into the outside, some of the oil is deteriorated. When the metamorphic components and impurities reach a certain degree, the color of the oil changes, the viscosity and acid value increase, and insoluble resin like substances are precipitated, which results in the increase of vapor pressure and deterioration of performance of vacuum pump oil. At this time, the pump oil can no longer be used, and a new pump oil must be replaced.In order to prevent the dust and particulate matter in vacuum pump oil from entering the pump cavity along with the pump oil, continuous filtering device should be set up during the operation of the pump for some technological processes. After the dust, impurities and contaminated oil sink into the bottom of the main oil tank, they flow into the auxiliary oil tank through the oil return pipe. After separation and precipitation, the emulsified oil, water, dust and impurities sink into the bottom of the auxiliary oil tank and are discharged regularly by the discharge valve. The relatively clean oil is filtered by the filter in the upper part of the auxiliary oil tank, and then enters the oil separation chamber through the oil inlet pipe, and then supplies to the end cover and pump chamber.The filter element in the filter blocks the mechanical pollutants when the oil passes by and purifies the vacuum pump oil. The pressure gauge is often connected to the filter to show whether the filter is blocked. When the pressure increases, the oil cannot flow normally. The filter element should be cleaned or replaced.
