What should we pay attention to when using the vacuum pump system? Today we will introduce this knowledge to you, hoping that through our introduction we can better help you understand.
Before the vacuum pump system is put into operation, it is necessary to carefully check whether the fasteners in various parts are loosened or not, and if loosening occurs, the tightening must be corrected. Before starting, the water tank must be filled with water, open the inlet valve of the pump, and then run the anti-corrosion pump. It is strictly prohibited that the pump is dehydrated, idle and reversed to prevent damage to the seal, impeller and other parts of the pump body. Before the vacuum unit stops, it opens the vent valve or reduces the vacuum to less than 0.092 MPa before stopping. In order to prevent backdraft damage to check valve caused by excessive vacuum. If the check valve fails, please open the check valve cover and remove debris.
When using steam-water series jet vacuum unit, the steam valve should be opened before starting. When stopping, the steam valve should be turned off before stopping, so as to prevent damage to the water jet vacuum pump caused by excessive temperature. When installing steam pipeline in vacuum unit, the pipeline must be kept level to prevent water accumulation in the pipeline, otherwise the vacuum effect will be affected. The circulating water in the water tank should be replaced or supplemented frequently, and the lower water temperature should be kept as far as possible, because excessive water temperature will affect the exhaust volume and vacuum degree.
