W-type reciprocating vacuum pump working principle and structure

W-type reciprocating vacuum pump, it is a low-vacuum access to the equipment, its pumping speed range is relatively large, with the development of science and technology now, it is widely used in petroleum, chemical, pharmaceutical and other industries Vacuum treatment. W-type reciprocating vacuum pumps also have limitations, it is not suitable for pumping high oxygen content, explosive, and dust containing particles of gas. Because of its particularity, for the user, want to have a better product experience, understand how it works, for the progress of the work is very useful. W-type reciprocating vacuum pump working principle and structure shown in Figure for the reciprocating vacuum pump working principle and its organization chart, reciprocating vacuum pump is the main components of the cylinder 1 and reciprocating linear motion in which the piston 2, the piston is driven by a crank Linkage 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. Operation, the motor driven by the crank-rod mechanism (rotary motion into linear motion), the cylinder reciprocating piston. When the piston moves from the left end to the right end in the cylinder, the pressure in the left chamber decreases continuously as the volume of the left chamber of the cylinder increases. When the pressure in the left chamber is lower than the pressure in the container, Balance principle, the gas inside the container is continuously drawn into the left lumen through the inhalation valve 5, and the air is being inhaled at this moment. When the piston reaches the rightmost position, the left chamber of the cylinder is filled with gas. Then the piston moves from the right end to the left end, at this time, the intake valve 5 is automatically closed. The gas is gradually compressed as the piston moves from right to left. When the gas in the cylinder reaches the exhaust pressure, the exhaust valve 4 is opened at this time, and the gas is discharged to complete a working cycle. When the piston moves from the left end to the right end, the above cycle is repeated until a certain equilibrium pressure is reached by the drawn vessel. In the reciprocating pump, the suction valve and the exhaust valve are very important parts and are vulnerable parts, their work directly affects the reciprocating pump ultimate pressure, pumping rate, power consumption and reliability of the operation.Learn W Reciprocating vacuum pump working principle for the understanding of this product and research this product is of great significance, which not only can make better use of the product, but also can better protect the product, improve the service life of the product, bring bigger benefit.
