Reciprocating vacuum pumps, also known as piston vacuum pumps, have a greater pumping capacity than rotary vane vacuum pumps and have higher efficiency than reciprocating vacuum pumps, as well as reciprocating vacuum pumps Complicated, bulky but it has to face the embarrassment, so you want to better use of reciprocating vacuum pump, vacuum pump must work on the principle of reciprocity have enough understanding. Reciprocating vacuum pump works Reciprocating vacuum pump works as shown, the main components of the cylinder 1 and reciprocating linear motion in which the piston 2, the piston is driven by the crank mechanism 3 (including the crosshead) to complete. In addition to the main components mentioned above, there are also important components such as the exhaust valve 4 and the intake valve 5 as well as the auxiliary components such as the base, crankcase, dynamic seal and static seal. During operation, driven by the motor, the piston in the cylinder reciprocates through the action of the crank-connecting rod mechanism. When the piston in the cylinder from the left to the right end of the movement, as the left cylinder chamber volume increases, the cylinder gas density decreases, and the formation of pumping process, this time the gas is drawn into the container through the intake valve 5 into Pump chamber left. When the piston reaches the rightmost position, the left chamber of the cylinder is completely filled with gas. Then the piston moves from the right end to the left end, at this time the intake valve 5 is closed. The gas in the cylinder is gradually compressed as the station piston moves from right to left. When the pressure of the gas in the cylinder reaches or slightly exceeds one atmosphere, the exhaust valve 4 is opened to vent the gas to the atmosphere to complete a working cycle. When the piston moves from left to right, it repeats the previous cycle, so that it is repeated until it reaches a stable equilibrium pressure in the container. In order to improve the pumping efficiency, air intake valves and exhaust valves are generally provided at both ends of the cylinder, and then the intake ports and the exhaust ports at both ends of the cylinder are connected in parallel by pipes. Through the above description of the working principle of the reciprocating vacuum pump, I believe that the understanding of the reciprocating vacuum pump we went one step further, with the help of modern science and technology and the needs of the market, the future is not reciprocating vacuum pump is better or worse, in the face of such situation, Someone must stand up and take responsibility for the future of the reciprocating vacuum pump. This must not be the fight of one person, but the fight of the entire community. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
