Abstract
The invention discloses an automatic oil filling device of an oil rotary vane vacuum pump. The device comprises an oil inlet formed in an outer wall below a vacuum air suction port, a metallic pipe, a flow control valve and an oil suction pipe, wherein one end of the metallic pipe is connected with the oil inlet and the other end of the metallic pipe is connected with the flow control valve; one end of the oil suction pipe is connected with the flow control valve and the other end of the oil suction pipe is a free end which stretches into a vacuum pump oil barrel. The automatic oil filling device of the oil rotary vane vacuum pump can automatically fill oil to the vacuum pump under the situation of continuous operation without shutdown, vacuum pump oil is sucked in by using negative pressure produced by the vacuum pump air suction port during operation, the flow is adjusted through the flow control valve, the operation is convenient, simple and quick to perform, the influence on production is further reduced and the production efficiency can be effectively improved to a certain extent.
Description
Technical field
The present invention relates to a kind of supporting facility of vacuum pump, be specifically related to a kind of oily formula sliding vane rotary vacuum pump automatic fuelling device.
Background technique
Oil formula sliding vane rotary vacuum pump automatic fuelling device is widely used in metallurgy, machinery, military project, electronics, chemical industry, light industry, oil and medicine etc. and produces and scientific research department, vacuum pump is in operation and will ensures that oil level is normal, cause oil level to reduce through one section of final vacuum pump oil meeting loss working time, continue to run if added not in time, likely cause vacuum pump to damage.
Vacuum pump must be stopped when adding pumping fluid in actual production, turn on oil filler sealed screw, funnel is inserted oil filler, slowly poured in the pump housing by oil with spoon, if pump is also in operation, pumping fluid can outwards spray from oil filler by the malleation in pump, oil supplier's trouble of making comparisons is time-consuming, during oiling, vacuum pump stops cannot provide vacuum, production line needs the equipment of vacuum be all forced to wait of stopping, larger to Influence of production.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide and a kind ofly can ensure vacuum pump auto-oiled oily formula sliding vane rotary vacuum pump automatic fuelling device when continuous Nonstop running machine.
In order to achieve the above object, the technical solution used in the present invention is:
Oil formula sliding vane rotary vacuum pump automatic fuelling device, this device comprises the filler opening, metal tube, flow control valve, the oil-absorbing pipeline that are opened on vacuum suction mouth external wall beneath, and one end of described metal tube is connected with filler opening, the other end connection traffic control valve; One end connection traffic control valve of described oil-absorbing pipeline, the other end is that free end stretches in vacuum pump oil drum.
Aborning, when needing to add pumping fluid, open flow control valve, utilize the vacuum pump operationally negative pressure that produces of vacuum pump intakeport, the oil in vacuum pump oil drum is sucked the pump housing, and by the size of flow control valve gate control Journey to the West flow; When not needing to refuel, flow control valve is in closed condition.
In such scheme, preferably, the Placement of described filler opening and metal tube is for being threaded, and detachable thread connecting mode is conducive to I&M.
Compared with prior art, beneficial effect of the present invention is:
Oily formula sliding vane rotary vacuum pump automatic fuelling device of the present invention can reach and carry out automatic oiling when continuous Nonstop running machine to vacuum pump; the negative pressure that when running, vacuum pump intakeport produces is utilized to suck pumping fluid; and carry out adjust flux size by flow control valve; convenient and simple for operation, quick; further reducing the impact on producing, can effectively enhance productivity to a certain extent.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Figure number identifies: 1, vacuum suction mouth; 2, filler opening; 3, metal tube; 4, flow control valve; 5, oil-absorbing pipeline.
Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is further described:
The present invention's oil formula sliding vane rotary vacuum pump automatic fuelling device is formed primarily of the filler opening 2 be opened on vacuum suction mouth 1 external wall beneath, metal tube 3, flow control valve 4, oil-absorbing pipeline 5.
One end of described metal tube 3 is connected with filler opening 2, and preferably, the Placement of filler opening 2 and metal tube 3 is for being threaded, and filler opening 2 place is internal thread, and metal tube 3 place is the outside thread matched with it; The other end connection traffic control valve 4, this flow control valve 4 is switch, for the uninterrupted of the pumping fluid of control flow check warp; One end connection traffic control valve 4 of described oil-absorbing pipeline 5, the other end is that free end stretches in vacuum pump oil drum, as shown in Figure 1.
In actual production, when needing to add pumping fluid, open flow control valve, utilize the negative pressure that when running, vacuum pump intakeport produces, by the pipeline of oil-filling device, pumping fluid is sucked the pump housing by vacuum pump oil drum, flow control valve gate control oil suction uninterrupted, the excessive pump blade that causes of oil-feed flow can be effectively prevented to be subject to impacting generation sound, the too little refueling time of oil suction flow needs to lengthen, when vacuum pump oil level reaches normally, flow control valve cuts out, vacuum pump oiling work can be completed; When not needing to add pumping fluid, flow control valve is in closed condition, prevents barometric pressure from sealing in pump and causes vacuum leak.
Certainly; just by reference to the accompanying drawings the preferred embodiments of the disclosure is described in detail above; not limit practical range of the present invention with this, all equivalence changes done according to principle of the present invention, structure and structure, all should be covered by protection scope of the present invention.
