Do you know all the steps to use the vacuum pump? Follow the editor of china Two stage vacuum pump supplier to have a look!
1. Before normal operation and transmission, the vacuum pump should be tested for a trial run to check whether the vacuum pump has abnormal vibration and impact sound. For the vacuum pump used for the first time, the pressure of the vacuum pump should also be measured, which should meet the technical specifications. Under long-term working conditions, the temperature of the vacuum pump should not exceed 70 degrees. To determine the dry pumping speed. It is more complicated from dry to dry, and it is generally not inspected.
2. A mechanical vacuum pump with cooling water is required. Before starting the machine, the cooling water should be passed first, and then the machine should be started again. The outlet temperature of the cooling water should not exceed 30 degrees.
3. The pipes of the continuous vacuum pump and the pumped system should be as short and thick as possible, and the inner diameter of the pipe should generally be no smaller than the diameter of the air inlet of the dry vacuum pump to avoid the resistance of the dry pipe from affecting the pumping rate.

4. In order to keep the working room clean and hygienic, which is beneficial to the health of the staff, the exhaust gas should be directly led to the outdoors by using a leather tube.
5. Before use, check whether the vacuum pump oil reaches the oil mark line position on the window. At the same time, the direction of rotation of the motor pulley needs to be checked. The observer is facing the pulley, and the pulley should be rotated in a clockwise direction. If it rotates in the opposite direction, the two-phase connector in the phase power supply can be exchanged. Otherwise, the rotary vane vacuum pump will not be able to pump the air, but will pump the vacuum pump oil and atmosphere into the pumped system, causing serious pollution.
6. Pay attention to prevent hard materials (metal chips, glass fragments, etc.) from falling into the vacuum pump and scratching the moving parts of the vacuum pump. When the vacuum pump is not used for a long time, it should be stored in a dry and clean environment, and the suction port and exhaust port should be blocked to prevent dirt from falling into it.
