Abstract
The utility model provides a double connecting wave diaphragm pump and is the pump with the advantages of simple structure, good sealing property, big suction lift, not needing of adding leading water and energy saving. The double connecting wave diaphragm pump is composed of a transmission shaft, a transmission frame, an upper wave diaphragm, a lower wave diaphragm, an upper chamber in a pump body, a lower chamber in the pump body and a plurality of ofwater absorbing and discharging diaphragm one-way valves. When the transmission shaft moves up and down, the wave diaphragms fixed on the upper cross beam and the lower cross beam of the transmission frame are driven to swing up and down. The upper chamber and the lower chamber in the pump body are caused respectively to absorb the water and discharge the water and the water absorption and water discharging are alternatively carried out. The transmission shaft can be driven by hands, the electricity, the mechanical driving or other energy sources. The double connecting wave diaphragm pump can replace a hand pressing pump and can be used for multiple usages, such as the village water getting, irrigation, etc.
Description
The invention relates to and adopt the invention of water with pump.
Normal electronic vane pump and the piston type hand pump of using of water adopted in the rural area now, the common drawback of these two kinds of pumps is: must add diversion earlier before the pump water, after diversion formation vacuum, with water sucking-off from well, sometimes needing to add water several times could suck out water, use very inconveniently, piston type hand pump friction is big in addition, and efficient is low.
The objective of the invention is: a kind of simple in structure, good airproof performance, degree of vacuum height (it is big to inhale journey) are provided, need add diversion, energy-conservation pump.
Its solution is: by transmission shaft, transmission framework, the chamber up and down in convolution diaphragm, the pump housing, some to suction spring compression, that stream communicates and draining diaphragm type one-way valve up and down, constitute duplex convolution diaphragm pump.
The transmission framework fixedly is made up of screw thread on the slide bar of the left and right sides and lower and upper cross-member, and left and right sides slide bar can slide up and down in the pilot hole of pump housing both sides.
Upper beam is connected by the screw thread on the transmission shaft and last convolution diaphragm, compressing tablet, and bottom end rail is connected by bolt and following convolution diaphragm, compressing tablet.The circumference of convolution diaphragm was fixed tightly in the upper and lower end of the pump housing about the upper and lower end cover screw was incited somebody to action respectively.
Chamber communicated with water sucking mouth and drain opening about pump housing upper and lower end had, and the valve block of the draining diaphragm type one-way valve that the valve block of the suction diaphragm type one-way valve that some flow path communicate and some flow path communicate is pressed on the corresponding nozzle with spring.
The power source of transmission shaft can manual, electronic or mechanical transmission.
Accompanying drawing is a structural representation, and it has described embodiments of the invention.
The working principle of pump is as follows:
Transmission shaft (1) upwards, the left and right sides slide bar (15) (11) that drives upper beam (2), in the pump housing (24) both sides pilot holes (18), slides, drive bottom end rail (13) and also make progress, upper beam (2) is connect with following convolution diaphragm (12) by transmission shaft (1), bolt (14) and compressing tablet (3), last convolution diaphragm (4), compressing tablet (3) respectively mutually with bottom end rail (13).So when transmission shaft (1) makes progress, last convolution diaphragm (4) and following convolution diaphragm (12) also make progress, last convolution diaphragm upwards, make upper chamber (5) produce vacuum, the valve block (7) of last suction diaphragm type one-way valve overcomes the elastic force of spring (6) under the effect of suction, leave suction nozzle (8), and at this moment water is inhaled in the upper chamber (5), go up simultaneously draining diaphragm type one-way valve (22) under the effect of spring (21), will go up draining nozzle (23) and close.Transmission shaft (1) upwards, this at present convolution diaphragm (12) also make progress, lower chambers (17) pressurized, absorb water the down valve block (10) of diaphragm type one-way valve, under the elastic force effect of spring (6), the nozzle (9) that will absorb water is down closed, under the pressure effect of the valve block of following draining diaphragm type one-way valve (20) in lower chambers (17), overcome the elastic force of spring (21), leave down draining nozzle (19), the water in the lower chambers (17) is pressed towards drain opening and flows out.When as seen transmission shaft (1) makes progress, upper chamber (5) suction, lower chambers (17) draining, otherwise, when transmission shaft (1) is downward, upper chamber (5) draining, lower chambers (17) suction.
The circumference of convolution diaphragm (4) (12) was pressed on the two ends of the pump housing (24) about end cap (16) (25) was incited somebody to action respectively with screw up and down.
The working principle of Here it is duplex convolution diaphragm pump.
The duplex convolution diaphragm also can be used for purposes such as irrigation, hand blower, the hand gear pump of replacement.
Claims (4)
1, a kind ofly be used for the duplex convolution diaphragm pump that water is adopted in the rural area, it is characterized in that: transmission shaft (1), transmission framework, the chamber up and down (5) (17) in convolution diaphragm (4) (12), the pump housing (24), suction and the draining diaphragm type one-way valve that the spring compression stream communicates constitute up and down.
2, according to the described duplex convolution diaphragm of claim 1 pump, it is characterized in that: the transmission framework is by screw thread on the left and right sides slide bar (15) (11) and the fixing formation of lower and upper cross-member (2) (13), and left and right sides slide bar (15) (11) can slide up and down in the pilot hole (18) of the pump housing (24) both sides.
3, according to the described duplex convolution diaphragm of claim 1 pump, it is characterized in that: upper beam (2) connects with last convolution diaphragm (4), compressing tablet (3) mutually by the screw thread on the transmission shaft (1).
4, according to the described duplex convolution diaphragm of claim 1 pump, it is characterized in that: chamber (5) (17) communicated with water sucking mouth and drain opening about the pump housing (24) upper and lower end had, the valve block (20) (22) of the suction diaphragm type one-way valve that stream communicates uses spring (6) (21) to push down nozzle that absorbs water up and down (8) (9) and draining nozzle (19) (23) up and down respectively.
