Rotary vane vacuum pump is a common type of vacuum pump, such as our common 2X rotary vane vacuum pump is one of them, its structure and performance are very unique, and very good. Next, we will introduce its structural characteristics in detail. 2X rotary vane vacuum pump is bipolar structure. Its operation function is composed of high pressure stage and low pressure stage II. Its suction port is connected with vacuum vessel or vacuum equipment. During operation, a lot of gas in the vessel will be inhaled and discharged. When the equipment obtains vacuum, the high-pressure exhaust valve sheet will be closed, and the gas inhaled by the high-pressure stage will be transferred to the second stage, and then inhaled and discharged by the second stage, so that the vacuum equipment can obtain a certain vacuum. The technical parameters of the pump are 6 x 10-2 PA. According to the user's operation, it can be equipped with a vacuum booster pump, which can be used as the front pump. Because the pump's pumping force is strengthened, the front pump is pumped out successively, which can make your equipment obtain higher vacuum.
The pump is suitable for metallurgy, chemical industry, electric light source vacuum, vacuum coating, food packaging, medicine, plastic absorption, electronics, dryness and other fields.
Rotary vane vacuum pump is a kind of vacuum pump. If there are faults in the process of using, what should we do? Don't worry, we will summarize the common faults and solutions.
First, oil leakage can occur in many parts, oil leakage may be caused by these reasons, such as improper installation method, or inadequate sealing parts, or parts are damaged, there are impurities blocked, self-made rubber pad, oil resistance, but also consistent with the original shape, if the sealing surface is large, very good. If it is loose, it will leak oil.
Secondly, if the rotary vane vacuum pump does not rotate, do not immediately open the vacuum pump if you do not know what the reason is, in order to prevent the failure from aggravating, see if the hand can be turned. If you can coil, but do not rotate, to see if the coupling is bad, there are motor conditions, if not coil, or very laborious, to see the start of the pump temperature, pump oil viscosity is not high, if stopped, the pump returns to a lot of oil, we have to consider whether the oil level is too high reasons and so on.
Thirdly, the pump temperature is very high. There is a limit value of the pump temperature on the general instructions. If the limit value is exceeded, the viscosity of the pump oil will be reduced, which will affect the efficiency of its pumping and damage the rubber parts.
Above are some common problems and solutions of rotary vane vacuum pump in use.
