Membrane pump with pneumatic drive high suction depth energy saving device
Technical field
The present invention relates to a kind of membrane pump with pneumatic drive high suction depth energy saving device.
Background technique
Pump is a kind of a kind of machinery of carrying liquid or making the liquid boost pressure.Membrane pump with pneumatic drive is that air pressure can be passed to liquid, and liquid energy is increased, and mainly is used for the liquid and the hypertoxic liquid of transporting water, oil, chemical industry solvent, corrosive liquids, band particle.But also exist deficiency, as inhaling the problem of journey.It is 5.48 meters that high level cadre inhales journey, and maximum wet to inhale journey be 7.6 meters.And under real working condition, such suction journey can't be used, and like 20 meters of vertical suction journeys, this pump just can't rise to liquid more than 20 meters.On the deck of shipyard 10000-ton class vessel that the suction of the water at the bottom of the storehouse is clean in the Orient, and existing diaphragm pump can't reach such level.
Summary of the invention
Because the problems referred to above that existing technology exists, the present invention proposes a kind of membrane pump with pneumatic drive high suction depth energy saving device, and it can effectively address the above problem.
To achieve these goals, the present invention has adopted following technological scheme:
The present invention proposes a kind of membrane pump with pneumatic drive high suction depth energy saving device; Comprise a diaphragm pump; Which is provided with an import, outlet, and be connected with a suction tude, suction tude is connected with a source of the gas input pipeline and is connected with the suction port of this diaphragm pump through a manual ball valve, air-filtering pressure regulator valve with after leaking the formula ball valve successively; Connect one first pipeline in inlet; Another opening of this first pipeline straight down and connect first end of a threeway, second end of this threeway is connected with the source of the gas input pipeline through a tracheae, and this tracheae is provided with a manual ball valve and an air-filtering pressure regulator valve; The 3rd end of threeway connects second pipeline straight down, and this second pipeline is provided with bottom valve.
As further characteristic of the present invention, the second pipeline low side also is connected with a filter cleaner.
As further characteristic of the present invention, bottom valve is an one-way valve.
As further characteristic of the present invention, source of the gas is a pressurized air.
Owing to adopt above technological scheme, membrane pump with pneumatic drive high suction depth energy saving device of the present invention can be with 20 meters of the suction Cheng Tigao of pump, use convenient, the saving energy, increase the benefit.

Embodiment
According to accompanying drawing and specific embodiment the present invention is described further below:
As shown in Figure 1; A kind of membrane pump with pneumatic drive high suction depth energy saving device comprises a diaphragm pump 1, which is provided with an import 2, outlet 3; And be connected with a suction tude 4; Suction tude 4 is connected with a source of the gas input pipeline and successively through a manual ball valve 7, air-filtering pressure regulator valve 6 with leak formula ball valve 5 backs and be connected with the suction port of this diaphragm pump 1, connects one first pipeline 12 at import 2 places, and another opening of this first pipeline 12 straight down and connect first end of a threeway 8; Second end of this threeway 8 is connected with the source of the gas input pipeline through a tracheae 9; And this tracheae 9 is provided with a manual ball valve 7 and an air-filtering pressure regulator valve 6, and the 3rd end of threeway 8 connects second pipeline 13 straight down, and this second pipeline 13 is provided with bottom valve 10.
In the present embodiment, the low side of second pipeline 13 is provided with a filter cleaner 11, and vertically stretches in the water, and this filter cleaner is formed by slipping through the net, and can prevent that foreign material from getting in the diaphragm pump, increases the working life of diaphragm pump; Bottom valve 10 is an one-way valve, makes water suck then can not fall back; Source of the gas is a pressurized air.
During use, open manual ball valve 7 and air-filtering pressure regulator valve 6 and leakage formula ball valve 5 on the suction tude, regulate air inflow; Give diaphragm pump 1 certain air pressure, diaphragm pump 1 is started working, and water is picked up by diaphragm pump 1; Get in the diaphragm pump 1; At this moment, the suction journey of diaphragm pump 1 can only reach about 7.6 meters, can't be with low again water sucking-off; Open manual ball valve 7 and air-filtering pressure regulator valve 6 on the tracheae 9; Regulate air pressure; Make air become stingy blister from threeway 8, to get in the diaphragm pump 1 through the first vertical pipeline 12, the suction journey of diaphragm pump 1 is improved greatly this moment, can increase about 20 meters suction journey.
This cover membrane pump with pneumatic drive high suction depth energy saving apparatus of present embodiment can be successfully with the sewage of hull bottom below 20 meters, above being pumped into endlessly, moves very steadily, makes the use of membrane pump with pneumatic drive at shipbuilding industry, and good prospect has been arranged; Make membrane pump with pneumatic drive in the high suction depth field, reliable assurance has been arranged, reliable use value is arranged.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
