Description
Technical field
The present invention relates to a kind of device for excluding oil seal type oil-sealed rotary pump tail gas condensing water, it is mainly used for intercepting, collects
The water droplet on oil seal type oil-sealed rotary pump exhaust pipe wall is condensed into discharge, prevents from polluting in condensate return to the pump housing
Pump oil.
Background technique
Oil-sealed rotary pump refer to using machinery, physics, chemically or physically chemical method to being evacuated by pumping container and
The device for obtaining, improving, maintaining vacuum.Wherein, common oil seal type oil-sealed rotary pump mainly has sliding vane rotary vacuum pump (abbreviation blade
Pump) and sliding valve vacuum pump (abbreviation slide valve pump), operating pressure range is 1.01 × 105~1.33 × 10-2Pa belongs to low vacuum
Pump.These pumps both can be used alone, and can also be used as the fore pump of other high-vacuum pumps or ultrahigh vacuum pump, be China its people
Essential main force's pump kind, is widely used to aerospace, military project, low temperature during economic every profession and trade application vacuum technology
The production such as equipment, vacuum equipment, electronics, chemical industry, light industry, petroleum and medicine and scientific research department.
When oil seal type oil-sealed rotary pump is evacuated vacuum chamber individually or as fore pump, from the higher pump oil of temperature
In the row of exhausting-gas hole that is pumped by these of the tail gas that is discharged to atmosphere, tail gas be containing a certain amount of certain condensable gas (mainly
Water vapour) and incoagulable gas (also referred to as permanent gas, mainly air) mixture.When the coercibility water vapour in tail gas is met
To room temperature tail gas tube wall when condense into water droplet, along tail gas tube wall flow back into the pump housing in the pump housing oil formed oil mixing with water
Object makes the ultimate vacuum of oil seal type oil-sealed rotary pump be deteriorated, destroys the pumping performance of pump.If in oil-sealed rotary pump gas vent and tail
Tracheae junction increases installation one and intercepts, collects and be discharged the device for condensing into the water droplet on tail gas tube wall, prevents from cold
Condensate flows back into pump housing pollution pump oil, to extend the service life of pump oil.
Summary of the invention
The present invention intends to solve three connected problems: (1) condensed water barrier structure, it is therefore an objective to intercept along exhaust pipe
Wall flows back into the condensed water in the pump housing.When the higher coercibility water vapour of temperature encounters the exhaust pipe wall of room temperature in tail gas
Water droplet will be condensed into, water droplet is along exhaust pipe wall constantly toward dirty.Therefore, it is devised in the approach that water droplet flows down
One structure for stopping water droplet dirty.(2) condensation water collection structure, it is therefore an objective to collect condensed water.After water droplet is blocked, it can hinder
It is constantly accumulated at gear, therefore the structure of a collection condensed water has also been devised in the present invention, prevent condensed water from overflowing at blocking,
The pump housing is flowed back into again.(3) condensed water draining structure, it is therefore an objective to condensed water be discharged.Regardless of the capacity of condensation water collection structure
Have it is much, always have receipts it is full when, therefore the structure of a discharge condensed water is devised in the present invention again.
(contain condensed water barrier structure, collection structure and discharge knot in inside by the grease condensing collector of bespoke design
Structure, the present invention can solve the problem of oil seal type oil-sealed rotary pump emulsifies pump oil along the dirty condensed water in tail gas exhaust next door.

Specific embodiment
For the technical solution for more understanding the technical problems to be solved by the invention He being proposed, with reference to the accompanying drawing and
Specific embodiment is described in detail.
As shown in Figure 1, in figure: 1, oil seal type oil-sealed rotary pump；2, damping hose；3, oil and water trap；4, water-oil separating
Device；5, the principle of ball valve apparatus of the present invention is the tail gas (oil gas) that oil seal type oil-sealed rotary pump 1 is discharged, and is arrived by damping hose 2
Up to oil and water trap 3, tail gas (oil gas) is condensed into oil water mixture in oil and water trap, which is received by grease
The discharge structure of storage reaches oil water separator 4, and under the action of oil water separator, the water separated is exhausted by ball valve 5,
The oil seal type mechanical vacuum pump housing for the oil reflux separated, can save pumping fluid.
As shown in Fig. 2, in figure: 21, tail gas (oil gas)；22, grease condensing collector outer tube (internal diameter D1)；23, oil-water fluid
Drop；24, grease condensing collector inner tube (outer diameter D2< D1)；25, condensation water collection structure；Oil gas condenses in oil and water trap 3
Principle at oil water mixture is the high-temperature oil gas from oil and water trap inner tube 24, encounters the oil and water trap outer tube 22 of room temperature
When water droplet (oil water mixture) is condensed on outer tube, due to outer tube diameter D1Greater than inner tube outside diameter D2(i.e. condensed water blocking junction
Structure), so condensing drip will not flow back to again in oil and water trap inner tube 24, but along the inner wall stream of oil and water trap outer tube 22
The oil water mixture gathered is discharged to water-oil separating to condensation water collection structure, then by the ball valve of condensed water draining structure 26
Device.
