Background technology
Existing claw shape dry type vacuum pump is to adopt paired claw rotor structure, by its transmission that is meshing with each other, will through rotor synchronous opposite direction be compressed from the gas that inlet chamber enters, be discharged to the next stage air inlet from exhaust outlet, next stage repeats above process successively, reaches the purpose that vacuumizes.
But there is following shortcoming in existing vavuum pump: in vavuum pump work after the regular hour, especially containing dust, or contain in the gas in the environment of the gas that can condense or the gas that is corrosive, under in the pump housings at different levels and gas passage, will depositing, influence the operate as normal of claw shape dry type vacuum pump, serious meeting causes its operate as normal or brings destructive consequence.Therefore turn round after certain working time, pump almost all need be disintegrated so that cavity and gas passage are thoroughly cleaned.
Summary of the invention
The objective of the invention is to solve the weak point in the above-mentioned prior art problem and provide a kind of and pump need not done under the situation of any disintegration, the cleaning device of the claw shape dry type vacuum pump that effectively inside cavity at different levels and gas passage at different levels is thoroughly cleaned with the very short time.
The technical solution used in the present invention: a kind of cleaning device of claw shape dry type vacuum pump, be provided with dividing plates at different levels between its pump housings at different levels, the pump housings at different levels connect vent valve; Driving shaft connects motor output shaft by shaft coupling, driven gear on the driving gear engagement driven shaft on the driving shaft, fuel tank is connected between base and the motor, and the top and bottom of described dividing plates at different levels are provided with top gas passages at different levels and bottoms at different levels gas passage.
The top and bottom of the described pump housings at different levels are provided with top gas passages at different levels and bottoms at different levels gas passage.
On described top gas passage at different levels and the bottoms at different levels gas passage overhead-valve doors at different levels and bottom valve at different levels are installed; Overhead-valve doors at different levels and bottom valve at different levels communicate with dividing plate inner chambers at different levels or pump housing inner chamber at different levels by top gas passages at different levels and bottoms at different levels gas passage.
The positive beneficial effect that the present invention is compared with prior art had:
1. when pump chamber and gas passage thereof need clean, pump need not done under the situation of any disintegration, just can thoroughly clean inside cavity at different levels and gas passage at different levels effectively with the very short time, the dust of pump inside and coagulation etc. are got rid of smoothly, and returned to the standard of dispatching from the factory fully;
2. reduce maintenance or overhaul cost significantly, prolonged maintenance or overhaul life effectively;
3. can clean pump chamber and passage thereof as required in the course of the work;
4. simple in structure, economical and practical, can be widely used in industries such as chemical industry, space flight, nuclear industry.
