Rotary vane vacuum pump exhaust pressure

Analyze whether the high exhaust pressure of the rotary vane vacuum pump will have an effect:


The rotary vane vacuum pump can remove the dry gas in the sealed container. If the gas ballast is attached, a certain amount of condensable gas can be removed. However, it is not suitable for removing excessive oxygen, corrosive to metals, chemical reactions to pump oil, and gas containing particle dust. Also a drying production line, water yan gas condensation within the pump and form oil emulsified turbidity, in order to stop the pump when the police returned to the oil, which breeds within the pump noise and vibration of the many companies deal with rotary vane vacuum pump has a very strong interest, have also attend the innovation step team, perfect of the senior enterprise, with well-funded companies, also have skill enterprises with professional knowledge, although there are many companies just to dividend, significantly low energy consumption, drying single-stage rotary vane vacuum pump water protected, often also can produce cavitation signs, now the new power network is growing into connection between supply and demand both sides of the emergency similar channels, comprehensive benefit is very considerable, and in terms of the layout of the rotary vane vacuum pumps, orderly by the air inlet into the workshop.

The maintenance method of rotary vane vacuum pump:


The pump is overhauled after a long period of operation (usually 2500h). All parts should be removed and cleaned during overhaul, and the cleaning solution of metal parts should be cleaned when cleaning. The worn parts should be replaced during cleaning. Disassembly sequence of rotary vane vacuum pump in overhaul: remove the power supply and remove the pump from the equipment; Open the drain plug and drain the cooling water; Open the oil plug, turn the pulley, release the pump oil; Remove the belt and remove the pulley and key; Remove the end cover of vacuum chamber; Remove the sealing ring and remove the positioning pin; Take out the low vacuum rotor and rotor, and draw the rotor with the hand to prevent the spring from popping. Remove the high vacuum end cover with the above method and pull out the rotor and rotor. The general assembly procedure and the notes of the rotary vane vacuum pump. To ensure the cavity tangent point of the rotor and the pump clearance, should will vent downward, the rotor into pump cavity, after using the weight of the rotor rotor and the pump cavity tiejin, which can automatically find is, guarantee the tangent point gap.


The specific procedure is:


 put the spring on the rotary piece, then put the spin piece into the rotor, and pressure several times with the hand, no resistance can; The high vacuum and low vacuum side rotor are respectively loaded into the pump chamber, and then the sub-shaft is improved. Cover, pulley, belt and exhaust valve; Fill the oil mark, fill the oil, then try to smoke.

First principle and results of products are available for thorough acquaintance, what's the first step of rotary vane vacuum pump is a vacuum, if you are don't understand the problem, to deal with the higher vacuum degree of vacuum pump, when the vacuum degree necessary for the pump or the gas pressure is not high, so a man can be priority in single pump selection, and when the rotary vane vacuum pump, all of a sudden power failure automatic blocking gas circuit to connect pump in the vacuum state and is equipped with pumps and control the layout, so late to deal with things, will also have a lot of way vacuum is in the given space below an atmospheric pressure gas state called a vacuum.


The vacuum container and in the vacuum state are under the effect of atmospheric pressure, and under the vacuum state the molecules of the gas density is less than the density of gas molecules of atmospheric condition, therefore, between the molecules and the probability of collision between molecular and solid appearance is less, its inlet connected to the vacuum container or vacuum configuration, working gas of when the container will be inhaled and, also is to say when the configuration is vacuum, high pressure stage exhaust valve will be closed, high level suction gas will be transferred to the second, and the secondary suction and exclusion, this vacuum configuration available for certain vacuum, and this kind of enterprises, their rotary vane vacuum pump innovation perfect things are fundamentally based on in on the results of the reform.
