Abstract
The utility model relates to a reciprocative vacuum pump for lifting water, comprising a cylinder body, a piston and a piston stem rod. The cylinder body is divided into a front cavity and a back cavity by the piston, the front cavity and the back cavity are respectively provided with a water inlet pipe and a water outlet pipe, the water inlet pipe is provided with a check inlet valve, and the water outlet pipe is provided with a check outlet valve. The utility model has the advantages of reciprocative bidirectional work, continuously liftingwater, high absorption degree and pumping, high efficiency, simple structure, convenient operation, low cost and strong applicability, and electric power, animal power or human power can be used.
Description
The utility model relates to a kind of liquid conveying machinery, particularly a kind of reciprocating type bidirectional vacuum lift pump.
A lot of local level of ground water are lower in China, cause big difficulty to people and animals' drinking water and irrigation by pumping, in order to address this problem, following method at present commonly used: the one, adopt submersible pump, but, and have high input inconvenient maintenance because of many local nothing electricity, electricity shortage or voltage instability are difficult to promote.The 2nd, adopt hand pump, easy to operate though cost is low, this pump belongs to unidirectional acting, and efficient is low.
The purpose of this utility model be provide at above-mentioned the deficiencies in the prior art a kind of reciprocating type two-way work doing, continuously water lift, inhale that journey is big, lift is higher, efficient is high, simple and reasonable, easy to operate, reciprocating type bidirectional vacuum lift pump that cost is low.
The purpose of this utility model is achieved in that reciprocating type bidirectional vacuum lift pump, comprise cylinder body, piston and piston rod, piston is divided into ante-chamber and back cavity to cylinder body, on ante-chamber and back cavity, be respectively equipped with intake pipe and outlet pipe, but intake pipe is provided with the check inlet valve, but the intake pipe that outlet pipe is provided with on check flowing water Valve, ante-chamber and the back cavity links to each other by the water inlet threeway, and ante-chamber links to each other by the water outlet threeway with outlet pipe on the back cavity.The auxilliary cylinder in auxilliary cylinder and back before the cylinder body both sides can be provided with, intake pipe and outlet pipe can be directly arranged on the auxilliary cylinder of preceding auxilliary cylinder and back.But but check inlet valve and check flowing water Valve are provided with to help and close elastic element.
Working principle of the present utility model is: piston is done the straight line back and forth movement in cylinder body, and a side cavity of piston forms vacuum state, and inlet valve is opened, and flowing water Valve is closed, and realizes water inlet; The opposite side of piston is compressed, and produces pressure, and inlet valve is closed, and flowing water Valve is opened, and realizes water outlet.So return multiple, realized coming and going all intake, the purpose of water outlet.
In the utility model, can adopt the acting of motor drives piston, also can adopt animal power or mode manually to realize water lift.
The utility model has the advantages that:
1, reciprocating type two-way work doing, two-way water inlet and water outlet, continuous water lift, suction journey and lift are big, efficient is high.
2, simple and reasonable, easy to operate, cost is low.
3, can adopt electric power, animal power or manpower to make this pump water lift, adaptability is strong, easily promotes, and is the ideal tools that vast rural area solves people and animals' drinking water, irrigates.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, in cylinder body (1), be provided with piston (2), the auxilliary cylinder (15) in auxilliary cylinder (14) and back before cylinder body (1) both sides are provided with, form a sealing pump chamber, piston (1) is divided into ante-chamber (12) and back cavity (13) to pump chamber, at preceding auxilliary cylinder (14) but on be provided with an intake pipe (4) that check inlet valve (8) are housed, and be provided with an outlet pipe (5) that check flowing water Valve (9) are housed, at the auxilliary cylinder (15) in back but on be provided with an intake pipe (6) that check inlet valve (10) are housed, and be provided with by water inlet threeway (16) and link to each other outlet pipe (5), (7) link to each other by water outlet threeway (17).
Claims (3)
1, reciprocating type bidirectional vacuum lift pump, comprise cylinder body (1), piston (2) and piston rod (3), piston (2) is divided into ante-chamber (12) and back cavity (13) to cylinder body (1), it is characterized in that: on ante-chamber (12) and back cavity (13), be respectively equipped with intake pipe (4), (6) and outlet pipe (5), (7), intake pipe (4), (6) but be provided with check inlet valve (8), (10), outlet pipe (5), (7) but be provided with check flowing water Valve (9), (11), intake pipe (4) on ante-chamber (12) and the back cavity (13), (6) link to each other the outlet pipe (5) on ante-chamber (12) and the back cavity (13) by water inlet threeway (16), (7) link to each other by water outlet threeway (17).
