Roots reciprocating vacuum unit is a new generation of vacuum unit product. It is mainly characterized by series reciprocating vacuum pump and is widely used. Its working process is as follows:


The roots reciprocating vacuum unit drives the cylinder piston to iron through the crank connecting rod mechanism under the driving power of the motor; When the piston moves from the left end to the right end in the cylinder, the density of gas in the cylinder decreases from time to time due to the increase of the volume of the left chamber of the cylinder.


At this time, the gas in the container enters the left chamber of the pump body through the suction valve: when the piston reaches the right end, the cylinder is filled with gas; When the piston moves from the right end to the left end, the suction valve closes and the gas in the cylinder at the left end is gradually compressed; When the pressure in the left cylinder reaches or slightly exceeds an atmospheric pressure, the exhaust valve is opened and the gas is discharged out of the atmosphere outside the machine, so as to complete a working cycle: Reciprocating until a stable equilibrium pressure is reached in the pumped container.


Compared with other types of units, roots reciprocating vacuum unit has the advantages of large air extraction rate and good vacuum stability, which can better meet the needs of customers.
