If the coupling of the coupling with the shaft is too loose and the concentricity of the hole and shaft is affected, the repair welding should be carried out. Stamping or pad copper on the shaft is a matter of expediency, not as an ideal method. 9 technical requirements, the so-called lift refers to the required lift, but not the height of the water, it is particularly important to choose the pump. The pump lift is about 1.15 to 1.20 times as high as the height of the water. If the vertical height of a water source to water is 20 meters, the required lift is about 23~24 meters. 50JMZ-40 portable alcohol pump Shanghai Liuzhou sub pump factory R & D and production of mobile alcohol pump in one of the models can flow 8m3/h mobile alcohol pump, which is 2.22 liters per second, and the material can be sent to a height of 40 meters, which is the type of pump head, the movable pump motor power of 4 kW with alcohol. The pump speed is 2900 rpm, and the inlet diameter is 50M.M. 50JMZ-40 portable alcohol pump pump shaft and the motor shaft is not the same as the heart; 4, foot screws loose. 1, adjust the river gate, to make it run within the set range of performance; 2, the impeller balance: 3, proofreading proofreading, the pump shaft and the motor shaft coaxially; 4, tighten foot screws. Eight. The bearing is overheated. 1, there is no oil in the bearing; 2, the shaft of the pump and the shaft of the motor are not on the same core line. 1, check, and, wash bearing body, add lubricating oil and oil; 2. proofreading the coaxiality of two axes on the same core line. It is suitable for use in factories, mines, urban water supply, power stations, tillage and seed field drainage irrigation and all kinds of hydraulic engineering. MA type metering pump metering pump metering pump, accurate measurement of Western narration as the fluid and the ideal dosing equipment, metering pump in various fields has now been widely used in pharmaceutical, food and beverage covers fuel chemical industry, in the process of shouldering the measurement of strong corrosive, toxic, high viscosity and high pressure media the addition of the job. Through more than half a hundred years of practical application and technical improvement, now the metering pump has entered its high speed period. Nowadays, the mature power driven form and the liquid delivery end (pump head) material technology need the new metering pump, which can almost accomplish the transportation no matter what common sense and special media requirements. Its working pressure and volume can also be satisfied with the large fraction requirement of industrial production. With the growth of many people's requirements for production process and automation level, welcome new and old customers to purchase Shanghai Long Ya brand 50JMZ-40 mobile alcohol pump.
