    Based on the multi-purpose vacuum pump for circulating water, according to the characteristics of small laboratory area, referring to the Japanese desk pump, the circulating pump is made of one-time formed shell and reduced volume It has the characteristics of small volume, light weight, beautiful appearance, double surface and double head pumping, Four watches and four taps, the same multi-purpose vacuum pump on both sides, even in the teacher's intuitive demonstration, students can turn on and off on either side Today, I summarized the common faults and solutions of the circulating water multi-purpose vacuum pump, hoping to help you I the vacuum degree is not high or the vacuum gauge refers to the location to be searched: 1 The motor speed is not enough or the voltage is too low; 2 The vacuum bottle and check valve are blocked or corroded by dirt; 3 The water inlet and filter pipe network are blocked; 4 The impeller is off; 5 The water inlet or air leakage of the vacuum gauge; 6 The vacuum pipe is blocked or the pipe is cracked; and the removal method: 1 Check whether the voltage is stable 2 Clean the internal dirt or replace the new bottle, valve core 3 Clean and take out the internal dirt 4 Replace the impeller 5 Throw out the water in the meter to make the meter needle return to zero or replace the new meter 6 Clean the pipeline or replace the new pipe 2 The motor does not work to find the position: 1 The fuse tube is burnt out; 2 The running capacitance is broken down; 3 The motor winding is burnt out; 4 The bearing is seriously worn and jammed; 5 The impeller is blocked and jammed; 6 The wire end is faulty welded or the wire clamp is loose; troubleshooting methods: 1 Replace the fuse tube; 2 Replace the new capacitor with the same voltage as the original capacitor; 3 Replace the motor 4 Replace the new bearing 5 Remove the sundries and correct the position of the impeller 6 Weld firmly and clamp the wire tightly 3 The motor is too hot and noisy Find out the position: 1 The bearing is worn 2 The impeller is worn and deformed 3 The voltage is unstable or too low Troubleshooting: 1 Replace the new bearing 2 Replace the impeller with a new one 3 Check whether the circuit is overloaded or low voltage
