Diaphragm pump is that a kind of collection high pressure, water saving, energy-saving and emission-reduction, automation are controlled in all over the body, Special Pump with high technology added value, be widely used in the industries such as Coal Chemical Industry, aluminium oxide, mine, pipeline coal transporting, this pump is kept apart fed sheet of a media and hydraulic medium by barrier film, barrier film is one of key components and parts of this pump, the life-span of barrier film is the diaphragm pump the key technical indexes, the key factor that determines membrane life be oil mass in oil pocket the number.When in oil pocket, oil mass is few, barrier film deflection deformation backward is excessive, when in oil pocket, oil mass is many, barrier film deflection deformation forward is excessive, no matter deflection deformation is excessive forward backward for barrier film, surpasses the deformation design scope of barrier film, and barrier film all will break very soon, affect complete machine operation and working life, therefore keep in oil pocket the oil mass balance most important.
The diaphragm pump upper oil cavitie is mended discharge equipment and is adopted unidirectional Fill valve and unidirectional draining valve both at home and abroad at present, be easy to cause oil mass mistake benefit in oil pocket to misprint, be that oil row unnecessary when in oil pocket, oil mass is many does not go out, when in oil pocket, oil mass is few, oil subsidy is not come in, oil mass imbalance in oil pocket like this, cause barrier film stress and strain to surpass scope of design, barrier film is short working life, affects the operational efficiency of complete machine.
The model utility content
Goal of the invention of the present utility model puts forward for the defect that overcomes current diaphragm pump existence, design a kind of oil mass in can the Precise Control of Oil chamber under detection system, keep oil mass balance in oil pocket, barrier film is moved in the design variations scope, thereby extend the gas control 2/2-way valve benefit discharge equipment of membrane life.Provide a kind of diaphragm pump to mend discharge equipment with the gas control 2/2-way.
Technical solution of the present utility model is to realize like this, this a kind of diaphragm pump is mended discharge equipment with the gas control 2/2-way, there is two-bit triplet oil extraction electromagnetic gas valve (9) and two-bit triplet repairing electromagnetic gas valve (10), it is characterized in that two-bit triplet oil extraction electromagnetic gas valve (9) connects two two-way draining valves (8) by pipeline, two-bit triplet repairing electromagnetic gas valve (10) connects two two-way Fill valves (11) by pipeline, two two-way draining valves (8) and two two-way Fill valves (11) are fixed on the base plate (7) of have oil exit pipe (6) and repairing pipe (12), the upper hydraulic pipe line (22) connected of base plate (7) is communicated with the oil pocket (4) of diaphragm pump, the repairing pipe is communicated with main fuel tank (1) by oil pump (2), oil exit pipe is communicated with drop tank (3).
Useful technique effect of the present utility model is: the repairing of the diaphragm cavity inside of diaphragm pump and the oil mass of oil extraction are controlled automatically, accurately and reliably, have improved the barrier film working life of diaphragm pump, thereby have increased on the whole the working life of diaphragm pump.Can improve 15%-20% in working life according to the statistics in working life of single diaphragm pump.
The accompanying drawing explanation
Embodiment
Below in conjunction with the embodiment who provides in accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this kind of diaphragm pump mended discharge equipment with the gas control 2/2-way, there is two-bit triplet oil extraction electromagnetic gas valve (9) and two-bit triplet repairing electromagnetic gas valve (10), it is characterized in that two-bit triplet oil extraction electromagnetic gas valve (9) connects two two-way draining valves (8) by pipeline, two-bit triplet repairing electromagnetic gas valve (10) connects two two-way Fill valves (11) by pipeline, two two-way draining valves (8) and two two-way Fill valves (11) are fixed on the base plate (7) of have oil exit pipe (6) and repairing pipe (12), the upper hydraulic pipe line (22) connected of base plate (7) is communicated with the oil pocket (4) of diaphragm pump, the repairing pipe is communicated with main fuel tank (1) by oil pump (2), oil exit pipe is communicated with drop tank (3).
Structure for core apparatus of the present utility model, the inside that is said two two-way draining valves (8) and two-bit triplet repairing electromagnetic gas valve (10) has a micromesentery (18), and this micromesentery is by driving the Sealing (16) of being controlled by return spring (17) under two-bit triplet oil extraction electromagnetic gas valve (9) or the effect of the electromagnetic force of two-bit triplet repairing electromagnetic gas valve (10) and air pressure.Realize the to-and-fro motion of Sealing (16) by the restoring force of spring and the elastic force of micromesentery under the control of two-bit triplet oil extraction electromagnetic gas valve (9) or two-bit triplet repairing electromagnetic gas valve (10), reach automatic oil draining or automatically repairing and automatically closing, stop repairing or stop the purpose of oil extraction.
The inner Sealing of said two two-way draining valves (8) is communicated with benefit oil drain passage (14) and the oil drain passage (13) of base plate (7) by seal valve (21) and oil extraction one-way valve (15).
The inner Sealing of said two two-way Fill valves (10) is communicated with benefit oil drain passage (14) and the repairing passage (20) of base plate (7) by seal valve (21) and repairing one-way valve (19).
The working procedure of device of the present utility model is described below:
The outlet that the utility model is mended the oil extraction electromagnetic gas valve is connected by lucite pipe with the suction port of 2/2-way benefit draining valve respectively, transverse holes and longitudinal hole are set on the valve base plate simultaneously, transverse holes does not communicate with longitudinal hole, and transverse holes communicates with oil pocket, forms oil pocket and mends oil drain passage; On repairing one-way valve and oil extraction one-way valve, longitudinal hole is set respectively; Transverse holes and longitudinal hole are set on oil inlet pipe and oil exit pipe, and transverse holes communicates with longitudinal hole; Longitudinal hole upper end, left side on the valve base plate communicates with the longitudinal hole on the oil extraction one-way valve, and lower end communicates with longitudinal hole on oil exit pipe, and oil exit pipe upper left side transverse holes communicates with drop tank, jointly forms oil drain passage; Longitudinal hole upper end, right side on the valve base plate communicates with the longitudinal hole on the repairing one-way valve, and lower end communicates with longitudinal hole on oil inlet pipe, and on oil inlet pipe, the right side transverse holes communicates with main fuel tank, jointly forms the repairing passage; The place, mating face of three sections longitudinal holes arranges respectively Sealing, in case stream oil is revealed.
The utility model is when oil pocket oil is few, in repairing electromagnetic gas valve closing control 2/2-way Fill valve, sealing surface is thrown off, oil with certain pressure in the repairing passage backs down one-way valve, mend oil drain passage through cavity and fill into oil pocket, now, because pressure in oil pocket is little and oil extraction electromagnetic gas valve Pneumatic pipe cleaner is crossed micromesentery Sealing and oil extraction one-way valve sealing surface are shut, stream oil can not discharged from oil drain passage; Oily when many in oil pocket, oil extraction electromagnetic gas valve closing control 2/2-way draining valve sealing surface is thrown off, stream oil with certain pressure in oil pocket enters drop tank through cavity benefit oil drain passage and oil drain passage, now because of repairing electromagnetic gas valve Pneumatic pipe cleaner, cross micromesentery by Sealing and repairing one-way valve sealing surface is shut and the repairing one-way valve can only allow stream oil to flow to the cavity direction, stream oil can not discharged from the repairing passage.
