When the vacuum pump is working, it will continuously discharge air from the pump body to form the vacuum degree required by the work at the suction port, that is to say, the exhaust pressure is also another main factor affecting the operation efficiency of the water ring vacuum pump
The exhaust pressure has a huge impact on the suction capacity of the vacuum pump and the power consumption of the shaft operation. When the vacuum pump system is running, if the exhaust pressure is larger, the suction volume of the vacuum pump will be smaller, and the power consumption of the corresponding shaft will be larger. On the contrary, when the exhaust pressure of the system is smaller, the suction volume of the vacuum pump will be larger, and the operating power consumption of the corresponding shaft will be smaller.
Therefore, in the actual operation and maintenance process, the exhaust pressure data of the vacuum pump system should be observed in real time. When abnormal exhaust pressure data occurs, corresponding measures should be taken immediately to update the entire vacuum system, so that the exhaust pressure of the vacuum system will be long-term. Maintain the value within the national standard or the manufacturer's recommended range to ensure that the vacuum pump is always under the optimal working conditions, and effectively improve the overall mechanical efficiency of the water ring vacuum pump.
