Due to Dry vacuum pump The characteristics of the advantages are relatively good, have been applied to various fields, has been recognized by everyone, want to guarantee. Dry vacuum pump The quality of the use of the following, we understand the operation of the dry vacuum pump.
Before starting the dry vacuum pump, check whether all parts of the vacuum pump are complete, check the oil level at the different oil level mirror, confirm that the oil level is about 3mm above the oil sight mirror, check and confirm the state of each valve of the vacuum unit, the technology inlet valve is closed, the inlet filter blowdown valve is closed, the outlet pipeline is unblocked, the outlet pipe drain valve is opened, the cooling water inlet pipeline and the outlet are opened. The pipeline valve is opened, the nitrogen line valve is opened, the purging gas pressure is 0.5bar, the nitrogen sealing gas pressure is 3bar, and the purge valve is closed.
When the dry vacuum pump is switched on, the field will be connected with the central control unit to confirm that it can start. The vacuum pump can be activated by the on-the-spot operation column start button, the discharge valve of the outlet pipe is closed, the nitrogen sealing gas flow rate is checked or adjusted, the flow rate is between 2.5 and 3L/min, the blowing valve is opened, the flow rate of the flowmeter is adjusted to the right level, and after blowing for 5 to 10 minutes, the blowing valve is closed, the process inlet valve is opened, and the entry system is cut. During the operation of the vacuum pump, the temperature of the body should be observed. The temperature can be controlled by adjusting the water quantity by the temperature regulating valve. The temperature should be controlled as much as 50 to 75 degrees Celsius, ensuring that the temperature is not more than 80 degrees.
When the dry vacuum pump is shut down, close the process inlet valve, open the purge valve, and purge the valve for 20 to 40 minutes, then close the purging valve, stop the shutoff button through the field operation column, close the nitrogen valve and close the cooling water valve. If the winter is not used for a long time, it is necessary to drain the cooling water in the body and the pipeline to prevent frostbite, and open the outlet pipe drain valve and the inlet filter drain valve to check whether or not. There is condensate.
Above we introduced the dry vacuum pump operation method, we can take a good look, because only the correct operation method, in order to ensure the efficiency of the vacuum pump, to achieve the desired effect, hope that the above content will help you.
