Before application, the product specification should be read carefully, and the quality of shipment should be checked after opening the case. Receive spare parts and technical documents, remove exhaust protective parts. According to the request device, wiring, trial steering. Water-cooled pumps receive water.
In order to avoid fuel injection due to oil return and reversal, the pump mouth should be opened first, and the oil in pump should be transferred to the tank by hand tray according to the rules. At the same time, check the oil level, should be above the oil mark center, but do not fill the oil mark, more to release.
Auxiliary method to distinguish steering. Put the sheath on the pump mouth, if it is absorbed after opening the pump, it is positive, blown off and reverse. The normal sound is positive, and the abnormal sound is reverse.
If a pneumatic solenoid valve is installed at the pump mouth, it should be installed horizontally and operated simultaneously with the pump.
Gas ballast valves should be used when the relative humidity is high or the condensable vapors such as water vapor in the extracted gas are used.
Vacuum pump oil is recommended according to the specification. Note that ester vacuum pump oil can not be mixed with mineral oil type vacuum pump oil and other oils. It must be cleaned strictly before it is replaced with ester vacuum pump oil.
The limit pressure of the pump shall be checked by a compact mercury vacuum gauge. Full pressure gauge should pay attention to pairing calibration and standby comparison of gauge and regulation. It is advocated to install a ball valve between the regulator and the pump under test. Closing the valve at unexpected time can prolong the operation time of regulation.
