Reciprocating vacuum pumps are low-vacuum devices that draw gas from vessels with internal pressure equal to or lower than atmospheric pressure. When operating these devices, the temperature of the evacuated gas must be maintained at 35 degrees Celsius In the following, if the user wants to make better use of the reciprocating vacuum pump, it is necessary to understand the structural drawing and the structure of the reciprocating vacuum pump sufficiently. Reciprocating vacuum pump structure and structural features Pump operation, driven by the motor, through the crank-rod mechanism, so that the cylinder reciprocating piston. When the Wang room in the waiting room from the deposit to the right when the final move. Due to the increasing volume of the left cavity of the cylinder, the density of the gas in the cylinder is reduced to form a degassing process. At this time, the gas in the container enters the left chamber of the pump through the intake valve 5. When the piston reaches the right position, 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 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 and the gas is discharged into the atmosphere to complete a working cycle. When the piston moves from left to right, it sucks in a part of the gas and repeats the previous cycle, repeating the process until the gas pressure inside the pump reaches the required pressure. In practical applications, in order to improve the pumping efficiency, the pump uses a double-acting cylinder, that is, the piston can compress and evacuate at the same time in both directions, which mainly depends on the distribution valve. Domestic w-type reciprocating pump is a single-stage double-acting pump. Reciprocating pump has dry and wet points. Dry pump only exhaust gas, wet pump can be pumping gas and liquid mixture. There is no structural difference between the two, except that the dead space in the wet pump and the size of the valve train are larger than the dry pump, so the wet pump has higher ultimate pressure than the dry pump. Reciprocating pumps are horizontal and vertical two types. Vertical pump from the structure and performance is more advanced, it is a horizontal pump replacement products. This structure of the reciprocating vacuum pump ensures that the power consumption of the reciprocating vacuum pump is reduced by 1/3 on average while the average floor area is reduced by 2/3. The vibration is reduced and the service life is long. Reciprocating vacuum pumps to achieve its value smoothly, inseparable from the hard work of many workers, as we enjoy all these benefits, must be responsible for the future of reciprocating vacuum pumps.
