Abstract
The invention discloses a membrane water pump which comprises a pump body and a power shaft penetrated through the pump body and further comprises a flexion resisting rubber hose and semicircle-shaped groove with a center of the circle placed in an axis of the power shaft. The flexion resisting rubber hose is embedded in the groove. The semicircle-shaped groove is fixed on the pump body. A cam is arranged on one end of the power shaft. The cam is provided with at least two lobes. A rotating shaft structure is arranged on each lobe portion. When the cam rotates, the flexion resisting rubber hose is pressed by the cam. According to the membrane water pump, the cam is used for pressing the flexion resisting rubber hose. The rotating shaft structure is arranged on the lobes portion of the cam, namely the lobes contact with the flexion resisting rubber hose in a rolling mode, and therefore abrade of the flexion resisting rubber hose is reduced and service life is prolonged.
Description
Technical field
The present invention is a kind of diaphragm pump.
Background technique
Diaphragm pump is to reach the machinery of carrying liquid or making the liquid supercharging via diaphragm element, can prevent effectively that the liquid carried is to the harm of water pump itself.Existing diaphragm pump generally adopts reciprocating part to drive the diaphragm element distortion, reach suction liquid, reciprocating part must be fixedly connected with diaphragm element or other transmission in this structure, so that the diaphragm element loss is serious, causes the working life of diaphragm pump short.
Summary of the invention
The purpose of this invention is to provide a kind of diaphragm pump, solve the anti-part short problem in working life of subduing in the existing diaphragm pump.
Purpose of the present invention is come specific implementation by the following technical programs: a kind of diaphragm pump, comprise the pump housing and the line shaft that wears on the pump housing, also comprise anti-rubber pipe and the center of circle semi-circular recesses on the axis of line shaft of subduing, this anti-rubber pipe of subduing is embedded in the groove, and this semi-circular recesses is fixed on the pump housing; This line shaft one end is provided with cam, and this cam is provided with at least two salient angles, and this salient angle place is provided with turning shaft structure; When cam rotated, this salient angle was flattened this anti-rubber pipe of subduing.
Further, described turning shaft structure is ball bearing, and the axle of this needle bearing is fixed on the salient angle place.
Further, the outer ring surface of this ball bearing is corresponding identical with the internal surface of described groove.
Further, this cam is provided with three salient angles.
Further, the angle that described groove is corresponding is 120-270 °.
Diaphragm pump of the present invention utilizes cam to push the anti-rubber pipe of subduing, and at the cam lobe place turning shaft structure is set, and namely salient angle contacts for rolling with anti-subduing between the rubber pipe, has reduced anti-wearing and tearing of subduing rubber pipe, has prolonged its working life.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described diaphragm pump of the embodiment of the invention.
Embodiment
As shown in Figure 1, the described diaphragm pump of the embodiment of the invention comprises the pump housing and the line shaft 1 that wears on the pump housing, also comprises anti-rubber pipe 4 and the center of circle semi-circular recesses 3 on the axis of line shaft 1 of subduing, this anti-rubber pipe 4 of subduing is embedded in the groove 3, and this semi-circular recesses 3 is fixed on the pump housing; These line shaft 1 one ends are provided with cam 2, and this cam 2 is provided with at least two salient angles 21, and this salient angle place is provided with turning shaft structure; When cam 2 rotated, this salient angle 21 was flattened this anti-rubber pipe 4 of subduing.Anti-two ports of subduing rubber pipe 4 are respectively the entrance and exit of fluid.
When line shaft 1 rotated, its overhead cam 2 rotations were by the anti-flow of fluid of subduing in the rubber pipe 4 promotion pipes of salient angle 21 extruding.Salient angle 21 places are made as turning shaft structure, and such as ball bearing, salient angle 21 contact with anti-subduing between the rubber pipe 4 as rolling, and namely 4 of rubber pipes are subject to radial effect power, and is stressed hardly on tangentially, reduced the wearing and tearing of rubber pipe 4, relatively prolonged its working life.
Owing to the anti-rubber pipe 4 of subduing will be embedded in the groove 3, so groove 3 is identical with rubber pipe 4, the corresponding need coincide the outer circumferential face of salient angle 21 and the internal surface of groove 3, can form the best collapsed state of subduing rubber pipe 4 to anti-like this.
Claims (5)
