一种用于过载保护水泵的隔膜

Membrane for overload protection water pump

Abstract

本实用新型公开了一种用于过载保护水泵的隔膜,包括基片,在基片中央设置用于与隔膜固定片形成圆形状密封腔的凹槽,在凹槽中间设置通孔,在凹槽表面四周均匀设置大小相同的通气孔。有益效果在于:1)在一种用于过载保护水泵安装该隔膜,其内部凹槽形成的腔室相互不干扰,但又相互无缝携接,工作效率高,工作压力大,基本杜绝水泵本身的二次污染,所以适用范围广。2)该隔膜采用橡胶设计,其整体工作平稳,震动少,噪音低。3)在凹槽表面设置通气孔,使得密封腔通气更加通顺。
The utility model discloses a membrane for an overload protection water pump. The membrane for the overload protection water pump comprises a substrate, grooves which form round sealing cavities with membrane fixing pieces are formed in the center of the substrate, a through hole is formed in the middle of each groove, and vent holes with the same size are uniformly formed in four sides of the surface of each groove. The membrane for the overload protection water pump has beneficial effects that 1) when the membrane is arranged at the overload protection water pump, cavities formed by the grooves therein are jointed seamlessly without interfering with each other, the working efficiency is high, the working pressure is high, the secondary pollution of the water pump is basically avoided, and accordingly the application range is broad; 2) the membrane is made of rubber, so that the work is stable, the vibration is small, and the noise is low; 3) vent holes are formed in the surface of each groove so that the sealing cavities can ventilate more smoothly.
