The use of the rotary vane vacuum pumps _

rotary vane vacuum pump is used to obtain low is one of the main pump in the vacuum pump and vacuum water pump. It can be divided into the oil seal and dry pump. According to the required degree of vacuum, can provide single pump and two stage pump, two stage pump application is more common.

rotary vane vacuum pump instructions

1. Before use, please read carefully the product instruction for use, and after unpacking check transportation quality. Collect the spare parts and technical documents, remove the exhaust baffle. According to the need to install, wiring and testing. Receive their water pumps.

2。 In order to prevent oil and the oil, should first open mouth, pump and pump oil to the fuel tank of memory by the regulation. At the same time, check the oil level, oil level should be higher than the mimeograph center, but don't move the oily be soiled, more should be released.

3。 Judge to auxiliary method. Pour sheath to a port on the pump. If it is pumping, it will be inhaled. It is forward, boasting and reverse. In square up sound is normal, voice is unusual in the opposite direction.

4。 If the port is equipped with pneumatic solenoid valve, pump should be installed horizontally and pump at the same time.

5。 When the relative humidity is higher or pumping water vapour in the gas can be condensed steam, such as gas ballast valve should be used.

6。 According to the manual, recommend the use of vacuum pump oil. Note ester vacuum pump oil won't mix with mineral oil type vacuum pump oil and other oil. Before use ester replaced vacuum water pump oil must be clean.

7。 Check the pump to the final compression mercury vacuum gauge pressure. All pressure gauge measurement and adjustment should be paid attention to the matching alignment and standby is adjusted. Installation of ball valve between the regulator and measured pump is recommended. When the valve is closed, the valve can be used for long-term use.

8, clean. Should not be impregnated to prevent washing liquid from entering the stitching inside the rotor and it is not easy eduction.

9, remove. On the advice of the operating instructions and regulations, maintain the good location, and properly placed, lest by mistake.

rotary vane vacuum water pump working pressure in the range of 101325 ~ 1. 33×10- 2 ( Pa） , belongs to the low vacuum pump. It can be used alone, also can be used as a high vacuum pump or other ultrahigh vacuum pump before use. Widely used in metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum, medicine and other production and scientific research departments.

rotary vane vacuum pumps can remove dry gas in the sealed container, and if the gas ballast device installed, you can remove a certain amount of condensable gases. However, it is not suitable for removal of oxygen is exorbitant, corrosive to metal, have chemical reactivity to pump oil, and gas containing dust particles.
