Constant to mechanical and electronic belt you know claw type dry vacuum pump _

What is a claw type dry vacuum pump

by the connection between the two type of claw rotor shaft of claw type dry vacuum pump, and is used to make the rotor and rotor and pump chamber, described in a closed chamber between the volume of the separator is not the lining of the gap in size between the inlet and exhaust the complete change of the friction in the process of joint.

structure of claw type dry vacuum pump generally adopts multilevel rotor series claw type dry vacuum pump structure, it has multiple roots rotor or in series form of rotor, the combination of a multistage claw type dry vacuum pump. Four series chamber, described in the pump chamber of each level has a pair of synchronous conjugated meshing claw rotor do reverse motion. Four primary pump chamber to the suction water pump room, this is bigger than inlet volume after three, between the compression level. Installed in two parallel axis, four pairs of rotor through bearing between the upper and lower shaft, a pump chamber and a separator with a stage, with the separator inlet and exhaust channel. A motor installation, described by gear power transmission to the rotor shaft, through a pair of timing synchronization and phase adjustment of the rotor shaft gear, to drive the rotor and fixed.

rotor and leave the pump chamber of small gaps between the rotor and rotor suspended in the flow section of the pump chamber, make no substantial frictional contact, do not need lubrication, this ensures the long-term stability can keep the limit of the ratchet pump vacuum extraction speed, the same compression ratio, long service life.

claw type dry vacuum water pump characteristic of

1) In the water pump room and other media does not contain any oil, cleaning time, environmental pollution;

2) High vacuum up to 3 pa;

simple 3) The structure, convenient operation and maintenance, low operating costs;

4) Long-term continuous operation under high pressure, with small noise;

5) Can pumping corrosive gas, poisonous gas, explosive gas, radioactive gas, dust and gas condensate gas ( Such as water vapor, organic gases, etc. ) ;

6) Do use the gas pump, as high as 10 - 105 a good compression ratio;

7) Suspended in the rotor pump chamber, the rotor between no contact between the rotor and the pump room, no friction, long life.

claw type dry vacuum pump application

petrochemical industry:

( 1) To pumping acid gases, such as tetrahydrofuran, etc. ( 2) To pump gas condensate, such as alcohol, gasoline, etc. ( 3) Can pump explosive gas, such as oxygen, hydrogen, methane, and similar objects.
