Today’s recommendation: liquid ring vacuum pump
EVP Pump Co., Ltd. is located in Shanghai. Our company has introduced a large number of professional and technical personnel, and has been focusing on product quality, thus winning a wide market. In the face of scientific and technological progress and domestic market competition, we have developed and produced a series of products, such as single-stage, double stage liquid ring pump, double suction split pump, chemical pump, roots pump, screw pump, etc., vacuum pump products of various specifications and models and various complete engineering equipment, which are highly praised by users.
1. The gate valve on the discharge line must be closed first.
2. Stop the vacuum pump.
3. In the cold season, the storage liquid in the vacuum pump body and the water in the bearing body cooling room should be emptied to prevent freezing and cracking of the parts.
1. Jog the self-priming vacuum pump, and pay attention to whether the rotation direction of the vacuum pump shaft is correct.
2. Pay attention to abnormal sound and vibration during rotation.
3. Pay attention to the readings of pressure gauge and vacuum gauge. When the readings of pressure gauge and vacuum gauge are stable after a period of fluctuation, it means that the vacuum pump has been filled with liquid and entered into normal infusion operation.
In summary, the liquid ring vacuum pump is based on the change of vacuum pump cavity volume to achieve suction, compression and exhaust, so it belongs to the variable volume vacuum pump. Compact structure, high number of pump revolutions, generally can be directly connected with the motor, no reduction device. Therefore, with a small structure size, a large exhaust volume can be obtained, and the floor area is also small. Compressed gas is basically isothermal, that is, the temperature change of compressed gas process is very small.
