Abstract
The utility model discloses an air inlet device of a single-level rotary-vane vacuum pump. The air inlet device of the single-level rotary-vane vacuum pump comprises a vacuum pump body, wherein an air inlet device is fixedly connected with one end of the vacuum pump body; an air suction opening is arranged above the air inlet device; an air inlet is arranged at one side of the air inlet device; an air filter valve is arranged on the air suction opening; and an air-liquid filter valve is arranged at one end of the air inlet. The air inlet device provided by the utility model not only can be used for filtering oil and water in a vacuum chamber, but also can be used for filtering impurities, such as thin and small sands and dust, in air, so that the service life of the vacuum pump can be prolonged.
Description
Technical field
The utility model has related to a kind of single-stage rotary-vane vaccum pump, especially a kind of air inlet system of single-stage rotary-vane vaccum pump.
Background technique
The general termination vacuum chamber of the air inlet system of common vacuum pump, another termination atmosphere, in actual mechanical process, the gas that sucks from vacuum chamber has liquid such as oil or water easily and infiltrates in the pump housing together, can bring the tiny grains of sand and dust impurity into from the atmosphere inhaled air, easy like this vacuum pump work is had some setbacks, also can reduce the working life of vacuum pump.
The model utility content
In order to overcome shortcoming of the prior art, the utility model provides a kind of air inlet system of single-stage rotary-vane vaccum pump, comprise vacuum pump body, it is characterized in that: the end in vacuum pump body is fixedly connected with air inlet system, the top of described air inlet system is intakeport, one side of described air inlet system is suction port, is provided with the air-filtering valve at described intakeport, is provided with the gas-liquid filteration valve at an end of suction port.
Air inlet system of the present utility model can filter the You Heshui in the vacuum chamber, and the tiny grains of sand and dust impurity in again can filtered air have prolonged working life of vacuum pump.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Reference character: 1. vacuum pump body, 2. intakeport, 3. suction port, 4. air-filtering valve, 5. gas-liquid filteration valve.
Embodiment
Below be to describe the technical solution of the utility model in detail by accompanying drawing.
As shown in Figure 1, a kind of air inlet system of single-stage rotary-vane vaccum pump, comprise vacuum pump body 1, end in vacuum pump body 1 is fixedly connected with air inlet system, the top of described air inlet system is intakeport 2, one side of described air inlet system is suction port 3, is provided with air-filtering valve 4 at described intakeport 2, is provided with gas-liquid filteration valve 5 at an end of suction port 3.
Air inlet system of the present utility model can filter the You Heshui in the vacuum chamber, and the tiny grains of sand and dust impurity in again can filtered air have prolonged working life of vacuum pump.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
