Abstract
The utility model discloses an electric diaphragm pump, which comprises a pump head and a motor which is matched with the pump head. A water inlet and a water outlet are respectively arranged on the pump head. The motor is connected with an inclined eccentric wheel through a first rotating shaft and the edge of the eccentric wheel is connected with a push rod which is capable of moving vertically through a spherical joint. The push rod drives a diaphragm sheet above the push rod to move and a water-pressuring cavity is arranged correspondingly above the diaphragm sheet. One end of the water-pressuring cavity is connected with the water inlet through a first one-way valve and the other end of the water-pressuring cavity is connected with the water outlet through a second one-way valve. The eccentric wheel of the electric diaphragm pump rotates in the working process and drives the diaphragm sheet to move up and down through the spherical joint driving and the push rod driving. According to the structure, the pushing force produced towards four sides is mutually offset on the position of the spherical joint when the eccentric wheel is rotating, the diaphragm sheet can only be in an up-and-down movement and the diaphragm sheet is guaranteed to be durable. The electric diaphragm pump is simple in structure and few in moving parts. The motor does not need to drive a complex structure and is easy to maintain. The working efficiency is improved.
Description
Technical field
The utility model relates to a kind of electric diaphragm pump.
Background technique
Diaphragm pump has very strong suction capacity (reaching 5M).Good through performance simultaneously, the liquid of diameter particle in the 1mm left and right sides can both pass through smoothly.Because barrier film will be transferred medium and transmission tool spare separates, need not the axle envelope, so medium can never outwards be revealed.General electronic barrier film all is through the driven by motor bent axle now, the bent axle drivening rod, and connecting rod push-and-pull barrier film moves reciprocatingly, thereby makes the pump chamber size variation reach the purpose of pump liquid.But this diaphragm pump is owing to complex structure, and moving parts is many, have a plurality of sliding friction surface that lubricated road need be set simultaneously, even need pressure lubrication, so efficient is not high, difficult in maintenance.
Summary of the invention
The technical problem that the utility model will solve provides a kind of electric diaphragm pump simple in structure, has high efficiency, and is easy to safeguard.
In order to solve the problems of the technologies described above; A kind of electric diaphragm pump of the utility model comprises the motor that pump head and pump head are supporting, is respectively arranged with water intake and water outlet on the pump head; Said motor is connected with the eccentric wheel of inclination through first rotating shaft; But this eccentric wheel edge is connected with the push rod of vertical motion through spherical joint, and push rod drives the diaphragm action that is positioned at its top, and diaphragm top correspondence is provided with the setting-out chamber; This setting-out chamber one end is connected with water intake through first one-way valve, and the other end is connected with water outlet through second one-way valve.
As the improvement of technique scheme, be provided with pressure regulator valve between said water outlet and the water intake, the opening direction of this pressure regulator valve points to water intake by water outlet.
As the improvement of technique scheme, said motor below drives through first rotating shaft has radiation fan.
The beneficial effect of the utility model is: drive through spherical joint when the eccentric wheel of electric diaphragm pump rotates during work and drive diaphragm with push rod and move up and down, owing to adopted said structure, eccentric wheel generation when rotating is hanged down each other at the spherical joint place to the thrust on four limits and is disappeared; Make diaphragm move up and down, guarantee that diaphragm is durable in use, this electric diaphragm pump simple in structure; Moving parts is few; Motor needn't drive complicated structure, safeguards easily, has improved working efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Embodiment
With reference to Fig. 1, a kind of electric diaphragm pump of the utility model comprises the pump housing 1; Be respectively arranged with water intake 2 and water outlet 3 on the pump housing 1, be provided with motor 4 in the pump housing 1, comprise pump head 1 and the supporting motor 4 of pump head; Be respectively arranged with water intake 2 and water outlet 3 on the pump head 1, said motor 4 is connected with the eccentric wheel 6 of inclination through first rotating shaft 5, but these eccentric wheel 6 edges are connected with the push rod 7 of vertical motion through spherical joint; Push rod 7 drives diaphragm 8 actions that are positioned at its top; Diaphragm 8 top correspondences are provided with setting-out chamber 9, and these setting-out chamber 9 one ends are connected with water intake 2 through first one-way valve 10, and the other end is connected with water outlet 3 through second one-way valve 11.Drive through spherical joint when the eccentric wheel 6 of electric diaphragm pump rotates during work and drive diaphragm 8 with push rod and move up and down, owing to adopted said structure, eccentric wheel 6 generation when rotating is hanged down each other at the spherical joint place to the thrust on four limits and is disappeared; Make diaphragm 8 move up and down, guarantee that diaphragm is durable in use, this electric diaphragm pump simple in structure; Moving parts is few; Motor needn't drive complicated structure, safeguards easily, has improved working efficiency.
In the present embodiment; Be provided with pressure regulator valve 12 between said water outlet 3 and the water intake 2; The opening direction of this pressure regulator valve 12 points to water intake 2 by water outlet 3, guarantees the stable of delivery pressure, thereby the assurance diaphragm can not guaranteed the diaphragm serviceability because of pressure is excessive and damaged; And need not the impressed pressure modulating valve in use, save the space.
Said motor 4 belows drive through first rotating shaft 5 has radiation fan 13, and the heat that motor produces when making diaphragm pump work can in time leave, the work safety of protection motor.
The above is merely the preferential mode of execution of the utility model, as long as realize that with basic identical means the technological scheme of the utility model purpose all belongs within the protection domain of the utility model.
