Hospital central vacuum system of the claw type dry vacuum pump -

claw type dry vacuum pump using the connection between the two pairs claw type rotor shaft, the rotor and the pump cavity wall and between the rotor and clearance between diaphragm and frictionless joint to form a closed cavity volume change to complete the suction and discharge process. Structure of

claw type dry vacuum pump structure generally use multilevel rotor series or roots rotor and multi-stage rotor series, in the form of the formation of multistage claw type dry vacuum pump.

four water pump chamber in series, in order to have a pair of each pump chamber rotor claw, claw rotor pitch, synchronous reverse movement.

4 primary pump chamber is in the pump chamber to the level, level 3, after the suction volume is greater than the formation stage compression.

4 installed in two parallel to the rotor shaft, shaft is supported by both ends up and down bearing, pump chamber is equipped with diaphragm between level and level, is equipped with suction exhaust passage on the diaphragm.

the motor installed upside down, by cross gear will be passed to the rotor shaft power. Rotor shaft driven by duration of a pair of synchronous gears, and adjust the phase of rotor and fixed.

between rotor and rotor and the pump cavity internal have small gap, the rotor suspended in the water pump cavity, over-current part without any real contact friction, do not need lubrication, make sure the claw type pump can long-term steady high vacuum degree, pump speed, constant compression ratio and long service life.

feature

pump chamber does not contain any media, such as oil, clean, empty, no pollution to the environment.

high vacuum, as high as 3 pa.

the utility model has simple structure, easy operation and maintenance, low operating cost.

can work continuously for a long time under high pressure and low noise.

it can remove corrosive gas, toxic gas, flammable and explosive gas, radioactive gas, dust and gas condensable gases ( Such as water vapor, organic gases, etc. ) 。 ) 。

can be used as a gas pump, compression ratio is 10 - 105.

the rotor to hang in the pump cavity, the rotor and the pump cavity no contact, no friction, long service life. Application

the petrochemical industry:

can remove acid gases, such as tetrahydrofuran.

you can remove the condensable gas such as alcohol, gasoline.

can remove inflammable and explosive gases, such as oxygen, hydrogen, methane, etc.

the anti-corrosion series can remove acid gases, such as hydrogen chloride gas, hydrogen fluoride gas, acid gas, etc.

the pharmaceutical industry: crystallization, distillation, distillation, drying, deodorant, polymerization, vacuum evaporation, vacuum filter, monomer recovery, adsorption/desorption and corruption, conveying of corrosive medium, such as ethylene oxide sterilization.

food industry: sublimation, dry and dehydration, vacuum evaporation, vacuum, vacuum packaging, etc.

research institutions: rotary evaporation, distillation, distillation, aggregation, negative pressure suction filter, vacuum drying, pilot, wind tunnel test, vacuum environmental simulation, etc.

electronic photovoltaic (pv) : dip, vacuum coating, ion etching, molecular beam epitaxy, etc.

aerospace: brazing, vacuum coating, electron beam welding, wind tunnel test and space environment simulation, etc.

metallurgical industry: dip, extrusion, vacuum coating, ion etching, mud degassing and degassing of liquid steel, such as molecular beam epitaxy.

the nuclear industry: zero leakage claw type pump can remove UF6 gas

other industries: central air conditioning, the indoor vacuum, sewage treatment, lithium battery manufacturing, etc.
