Abstract
The utility model discloses an oil formula sliding vane rotary vacuum pump automatic oiling device, the device be including seting up oil inlet, tubular metal resonator, flow control valve door on the outer wall of vacuum induction port below, inhale the oil pipe way, the one end of tubular metal resonator is connected with the oil inlet, and the flow control valve door is connected to the other end, inhale the one end connection flow control valve door that oil pipe said, the other end stretches into in the vacuum pump oil bucket for the free end. The utility model discloses can reach and carry out automatic oiling for the vacuum pump under the circumstances that continuous operation did not shut down, the produced negative pressure of vacuum pump induction port sucks vacuum pump oil when utilizing the operation to adjust flow dimension through the flow control valve door, convenient operation, simple, quick has further reduced the influence to production, to a certain extent can effectual improvement production efficiency.
Description
Technical field
The utility model relates to a kind of supporting facility of vacuum pump, is 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.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide and a kind ofly can ensures 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, technical solution adopted in the utility model 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, the beneficial effects of the utility model are:
Oily formula sliding vane rotary vacuum pump automatic fuelling device of the present utility model 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 utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
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, the technical solution of the utility model is further described:
The utility model 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 embodiment of the utility model is described in detail above; not limit practical range of the present utility model with this; all equivalence changes done according to principle of the present utility model, structure and structure, all should be covered by protection domain of the present utility model.
