Mine multistage centrifugal pump motor spindle can not overload use: centrifugal electric spindle when in use must be to secure a job at the specified speed spindle prohibited beyond processing, if regularly exceeds maximum processing speed of the spindle, then it It may cause the temperature rise of the spindle bearings, bearing grease dry, wear serious. In this case the bearing will be very easily damaged. Third, using the former mining multistage centrifugal electric spindle must first heat engine: To be honest reality is actually not how many manufacturers will follow this heat engine program DG46-30X3 multistage centrifugal pump, usually begins the normal processing of the boot. In fact, the role of the heat engine warm-up before with athletes is a reason, after the warm-up in order to achieve the best condition. Centrifugal electric spindle general heat engine pump, from 2000-5000-8000-12000-16000- highest DG25-50X10 multistage centrifugal pump, every five minutes is best. After the heat engine shaft to reach a steady state DG46-30X4 multistage centrifugal pumps, for high-precision machining it is necessary. These multi-stage centrifugal pumps for mining spindle maintenance methods you have clear? Do you know why your machine often wrong? These maintenance work you have done? You are not reverse the line , will result in serious damage to the machine. To prolong the life of the machine, hoping the operator can work, pay attention to maintenance work. Troubleshooting edit failure of a water pump does not absorb water pressure gauge and vacuum gauge pointer severe beating reasons: 1. Perfusion enough water piping and instrumentation 2. 3. The suction coupling at the leak is too high Remedy: 1. Check the bottom valve leaks. to hire enough water 2. Tighten the leak at 3. Reduce suction lift pump failure two non-absorbent vacuum gauge indicates high vacuum reasons: 1. Bottom valve does not open or have too much resistance suction line clogged 2. 3. filter clogging solve Measures: 1. Check the bottom valve 2. Replace the water-absorbing 3. Clean the filter DG25-50X10 multistage centrifugal pump _ _ multistage centrifugal pump provided by the Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd.
