Abstract
The utility model provides a pedal type diaphragm pump used for lifting water in a river pond and a well depression, which is composed of two diaphragm branch pumps which are connected in parallel, a pedal plate which is connected with diaphragms, a guiding mechanism, a curve lever linkage mechanism, and an armrest, wherein, the height of the armrest can be adjusted. The utility model has the advantages of high efficiency, safe operation, and low gravity center. The utility model is suitably fixed for using, and is suitable for a narrow river pond and a field ridge edge with loose and soft soil to be used in a flow mode. The utility model can pump and send clear water and dirt mud water.
Description
The utility model is to be used for the manpower water lift that draws water in river, the pool, well, depression.
Chinese patent specification 85202385 and Chinese patent specification 86206246 disclose two kinds of foot pumps, and its common ground is made up of two reciprocating pumps arranged side by side and pedal drive mechanism.These two kinds of foot pumps all are the manpower water lifts, but their deficiency is: the center of gravity of pump is higher, is suitable for the fixed position water lift, is not adapted at the moving use of the soft narrow river embankment ridge by-pass flow in soil very much.Piston and cylinder body have frictional loss, cause volumetric efficiency, mechanical efficiency to reduce.Especially when pumping the dirt that contains grit impurity, muddy water, piston, cylinder body quick abrasion make the pump lost of life.When extracting potable water, the piston that ferrous material is made, cylinder body adopt other material or uneconomical because friction easily produces the iron rust polluted water, and be perhaps not wear-resisting.
The foot-operated diaphragm pump of the utility model can address the above problem, thereby more convenient practicality, and use face is wider,
Foot-operated diaphragm pump is made up of the barrier film wheel cylinder and the footstep mechanism of two parallel connections.The pump housing can separate or whole the manufacturing.Barrier film adopts deflection material such as rubber, plastics etc. to make, and can make the shape of bellows or diaphragm.Two foot treadles directly connect with the barrier film of two wheel cylinders, link with roller, curve lever or pulley, traction rope between the foot treadle.In order to control foot-operated direction, foot treadle can have guide pin bushing, slides with respect to pump chamber on guide pillar.Certainly, also available some other foot-operated mode is come the driven pump barrier film: as the inner or outside mounting spring at barrier film, can cancel foot-operated linking mechanism, drive barrier film respectively by elastic force; Adopt indirectly foot-operated mode to drive barrier film, as foot-operated crankshaft ﹠ connecting, foot-operated swing-bar mechanism, foot-operated cam mechanism or the like.The utility model also is equipped with the handrail of adjustable height in the appropriate location of the pump housing, so that the operation of height difference person safety and comfort ground.
Because the center of gravity of the foot-operated diaphragm pump of the utility model is low, operation is difficult for toppling over, thus can not only fixed water lift, be more suitable for flowing and use at the soft narrow river embankment balk of soil property.Barrier film and pump chamber do not have friction makes pump efficiency higher, extracts not polluted water of potable water, does not influence the life-span of pump when pumping dirt, muddy water.
The concrete structure of foot-operated diaphragm pump is seen following examples and accompanying drawing.Fig. 1 is embodiment's a plan view, and Fig. 2 is its sectional view.Be described in detail according to the concrete structure that the utility model proposes below in conjunction with Fig. 1, Fig. 2.
The barrier film of this pump (7) is a cylindrical shape bellows (can be made into long-round-shape), and two is the sealed attachment foot treadle (6) and the pump housing (12) respectively.Exhaust dish (14) is arranged, in order to get rid of residual air in the barrier film.The pump housing is the casting integral body with two pump chambers, and the entery and delivery port of pump chamber is installed water inlet tee union (9) and water outlet tee union (10).Water-in and water-out are by inlet valve (13) and flowing water Valve (11) control.The foot treadle that has guide pin bushing can be gone up slip at directional post (8).Back shaft (3) is arranged, installation curve lever (5) on the lever dolly (15).The curve lever is exerted all one's strength and is transmitted between two foot treadles by being installed in roller (4) on the foot treadle.When the operator stepped on the foot treadle of stepping on certain wheel cylinder, bellows was compressed, and inlet valve is closed in the pump chamber, and flowing water Valve is opened, and liquid is discharged pump chamber; Simultaneously, the bellows of another wheel cylinder is stretched by lever, the inner negative pressure that produces, and suction is closed flowing water Valve, and inlet valve is opened, and liquid is inhaled in pump chamber and the bellows.Step on when stepping on another wheel cylinder, situation therewith antithesis.Step on so repeatedly and step on, just can constantly carry out the water lift operation.In order to make the operator use this pump safely, vertical rod (2), handrail (4) are equipped with in the front of pump, and adjusting screw (16) can be adjusted the height of vertical rod.
Embodiment's parameter: bellows diameter phi 150, pedal stroke 180, single pin reciprocal time 30 times/minute is inhaled 2 meters of journeys, 11 tons of flows/time.
Claims (5)
1, a kind of foot-operated barrier film (bellows, diaphragm) pump is characterized in that being made up of the barrier film wheel cylinder and the footstep mechanism of two parallel connections.
2, according to the described foot-operated diaphragm pump of claim 1, it is characterized in that two foot treadles directly connect with the barrier film of two wheel cylinders, and by roller, the interlock of curve lever or pulley, traction rope interlock.
3,, it is characterized in that to adopt the foot-operated barrier film mode that drives indirectly: as foot-operated crankshaft ﹠ connecting, foot-operated swing-bar mechanism, foot-operated cam mechanism etc. according to the described foot-operated diaphragm pump of claim 1.
4, according to claim 1,2,3 described foot-operated diaphragm pumps, it is characterized in that can be in the barrier film inside or the outside mounting spring of two barrier film wheel cylinders.
5,, it is characterized in that on pump, being equipped with the handrail of adjustable height according to claim 1,2,3,4 described foot-operated diaphragm pumps.
