Abstract
The utility model provides a self-priming pump. A pump shaft (3) in a pump body (2) is provided with a vane wheel (23) and a cam (4) respectively, a carrier rod (5) above the cam (4) is hinged with a link lever (6) and another link lever (21), a piston (9) at the upper end of the link lever (6) is provided with a spring (10), another piston (11) at the upper end of the other link lever (21) is provided with an air hole, a valve (20) is arranged above the air hole, and a baffle plate (16) is positioned between the shell and a water outlet pipe (14) and provided with an air hole. The self-priming pump does not need to be added with leading water before use, allows convenient use with low consumption of materials and a light pump body, and is capable of sucking water out even when the pump is operating at a low speed.
Description
The utility model provides a kind of water pump.
At present, have only the water pump of relatively large (more than four cun) just to have self-priming apparatus, and this apparatus structure complexity, cost of production is higher.More small-sized water pump does not generally all have self-priming apparatus, needs water in the pump housing earlier during use, sensation inconvenience during use, and water pump only when running up, could drink up water, and this water pump materials are many, and weight is big, the cost of production height.
The purpose of this utility model provides a kind of self-priming water pump, to improve the convenience of using.
The utility model is to realize like this, self-priming water pump, comprise housing, intake pipe and outlet pipe are arranged on the housing, impeller is installed on the pump shaft, cam also is installed on the pump shaft, and push rod one end of cam top is hinged on the housing, and the other end is hinged with connecting rod and another connecting rod respectively, piston in small end and the inflator links together, there is spring the piston top, and another piston in another connecting rod and another inflator links together, and there is valve the pore top of another piston, there is baffle plate the top of another piston, also there is valve the top of baffle plate pore, and baffle plate is also arranged between housing and the outlet pipe, and there is valve the pore top of this baffle plate.
Adopt the self-priming water pump of said structure easy to use, during use, water in housing earlier, simple in structure, materials are few, and are in light weight, and the water pump low-speed running just can drink up water.
Below in conjunction with description of drawings structure of the present utility model and working principle.
Fig. 1 is the cross-sectional schematic of the utility model structure.
As shown in drawings, the self-priming water pump of the utility model, comprise housing (2), intake pipe and outlet pipe (14) are arranged on the housing, impeller (23) is installed on the pump shaft (3), it is characterized in that, cam (4) also is installed on the described pump shaft (3), push rod (5) one ends of cam top are hinged on the housing, the other end is hinged with connecting rod (6) and another connecting rod (21) respectively, piston (9) in connecting rod (6) upper end and the inflator (7) links together, piston (9) outer rim has piston ring (8), between the inflator top cover of piston (9) and band pore spring (10) is arranged, another connecting rod (21) upper end is hinged with the pull bar (20) that links together with another piston (11), the pore top of another piston (11) has valve (19) to be hinged on another piston, the top of another piston is in addition with the baffle plate (12) of pore, the pore top of baffle plate (12) has valve (17) to be hinged on the baffle plate (12), the outer rim of another piston has piston ring (18), another piston (11) is installed in the inflator (22), between housing (2) and the outlet pipe (14) baffle plate (16) is arranged, the valve (15) that is positioned at the pore top on the baffle plate (16) is hinged on the baffle plate (16).
The top of inflator (22) can be equipped with the lid (13) of band pore.
During use, intake pipe is communicated with the water source.Under the drive of external force (motor or motor), pump shaft rotating band moving cam and wheel rotation.The projection of cam and push rod (5) promote two push rods and move up when contacting, and two push rods drive two-piston respectively and move up.Another piston (11) is when moving up, and the air pressure in the cavity between another piston and the baffle plate (12) increases, and valve (19) contacts with another piston, closes the pore on another piston; Valve (17) disengages with baffle plate (12), and the pore on the baffle plate is opened, and the pore of gas on baffle plate (12) discharged, and the water in the intake pipe progresses in the pump housing.When cam is rotated further, when its recess part contacts with push rod, under the effect of spring, push rod still keeps in touch with cam, another descent of piston, air pressure in the cavity between another piston and the baffle plate (12) reduces, valve (17) falls, and closes baffle plate (12) and goes up pore, and valve (20) breaks away from another piston, open the pore on another piston, the air in the housing enters the cavity between another piston and the baffle plate (12).So repeatedly, the air in the housing is discharged from gradually, and water progresses into housing, under the effect of impeller, discharges through outlet pipe, and water pump enters the state that normally draws water.
When water pump normally drew water, water was with the two-piston jack-up that makes progress, and cam no longer contacts with push rod (5), has avoided both wearing and tearing.
Draw water finish after, can the weep hole (1) by housing bottom be discharged by the water that retains in the housing.
