Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
A kind of electromagnetic type barrier film of the utility model pump structure as Figure 1-3, comprises the pump housing 1 and pump cover 11, and described pump cover 11 is arranged on the sidewall of the described pump housing 1, and the described pump housing 1 is fixedly connected with by bolt 12 with pump cover 11; Between the described pump housing 1 and described pump cover 11, be fixedly installed diaphragm 13, in described pump cover 11, be provided with piston rod 14, one end of described piston rod 14 is fixedly connected with by clamping plate 19 with described diaphragm 13, and the other end of described piston rod 14 is fixedly connected with armature 15; In described pump cover 11, be fixedly installed the first electromagnet 16 and the second electromagnet 17, described the first electromagnet 16 and described the second electromagnet 17 lay respectively at the both sides of described armature 15; The bottom of the described pump housing 1 is provided with water intake 2, and the top of the described pump housing 1 is provided with water outlet 10, and described water intake 2 is connected with water outlet 10; Be provided with the first one-way valve 3 at the described pump housing 1 near water intake 2 ends, be provided with the second one-way valve 8 at the described pump housing 1 near water outlet 10 ends.
As optimization, described the first one-way valve 3 and the second one-way valve 8 include steel ball 4, described steel ball 4 is arranged in steel ball seat 6, described steel ball 4 is connected with the pump housing 1 inwall elasticity by reed 5, described reed 5 can make one-way valve keep normally closed state, prevent that liquid from flowing backwards, strengthened the sealability of one-way valve, improved the utilization efficiency of diaphragm pump.
As optimization, between described the second one-way valve 8 and water outlet 10, be provided with accumulation of energy chamber 9, the effect of buffering water outlet 10 fluid pressures can be played in described accumulation of energy chamber 9, makes water outlet more steady.
As optimization, between described piston rod 14 and diaphragm 13, be provided with backplate 20, described backplate 20 sectional areas are greater than described piston rod 14, the edge of described backplate 20 adopts rounding processing, adopt the backplate 20 of large surface area, can reduce the pressure between piston rod 14 and diaphragm 13, prevent from causing because local compression is excessive the damage of diaphragm 13; In addition, the edge of backplate 20 adopts rounding processing, can make diaphragm 13 be out of shape under piston rod 14 pressure-actings time, is not damaged by the edge of backplate 20, improves the safety reliability of diaphragm 13, makes diaphragm pump have longer working life.
