Before 2SK water ring vacuum pump, it is necessary to check whether the rotation direction of the motor is consistent with that of the pump. After starting the vacuum pump, adjust the size of the water inlet, and then check whether the packing pressure is appropriate (normal packing pressure will make the water drop in the pump leak out). Sk-1.5b should first add water, then start the vacuum pump, and then adjust the size of the water inlet. The bearing lubrication is normal.
After 2SK water ring vacuum pump is started, it is necessary to observe whether there is vibration, listen carefully to whether there is noise in SK cantilever water ring vacuum pump, and measure the temperature of stuffing box and bearing (the normal bearing temperature shall not be 35 ℃ higher than the ambient temperature, and the working temperature shall not be higher than 70 ℃). If the temperature is too high, park the vehicle immediately to check the cause.
When SK cantilever water ring vacuum pump is used as the vacuum water diversion of the pump, during the operation of the pump, all air in the pump is sucked out until the water is sucked out to sk cantilever water ring vacuum pump in the future, that is, start the pump, stop the vacuum pump after the pump works normally, and seal the suction valve.
