QBY气动隔膜泵

QBY气动隔膜泵即能抽送流动的液体，又能输送一些不易流动的介质，具有自吸泵、潜水泵、屏蔽泵、泥浆泵和杂质泵等输送机械的许多优点。 1、 不需灌引水，吸程高达7米，扬程达70米，出口压力≧6kgf/cm2 2、 流动宽敞，通过性能好，允许通过最大颗粒直径达10毫米。抽送泥浆、杂质时，对泵磨损甚微； 3、 扬程、流量可通过气阀开度实现无级调节（气压调节在1-7 kgf/cm2之间 4、 该泵无旋转不见，没有轴封，隔膜将抽送的介质与泵的运动部件、工件介质完全隔开，所输送的介质不会向外泄漏。所以抽送有毒、易挥发或腐蚀性介质时，不会造成环境污染和危害人身安全； 5、 不必用电，在易燃、易爆场所使用安全可靠 6、 可以浸没在介质中工作 7、 使用方便、工作可靠、开停只需简单地打开和关闭气体阀门，即使由于意外情况而长时间无介质运行或突然停机，泵也不会因此而损坏，一旦超负荷，泵会自动地停机，具有自我保护性能，当负荷恢复正常后，又能自动启动运行； 8、 结构简单、易损件少，该泵结构简单，安装、维修方便，泵输送的介质不会接触到配气阀，联杆等运动部件，不像其他类型的泵因转子、活塞、齿轮、叶片等部件的磨损而使性能逐步下降； 9、 可输送较粘的液体（粘度在1万博以下）； 10、 本泵无须用油润滑，即使空转，对泵也无任何影响，这是该泵一大特点； QBY air operated double diaphragm pumps not only can exhaust the flow liquid, but also can convey some uneasy flowed medium, with the merits of self-pumping pump, diving pump, shield pump, slurry pump and impurity pump etc. 1、 It’s unnecessary to pour the drawing water, the suction lift reaches 7m height, the delivery lift reaches 70m length and the export pressure ≧6kgf/cm2 2、 Wide flow and good performance. The diameter allowed to pass the max grain reaches 10mm. the damage is very less to the pump while exhausting the slurry and impurity. 3、 The delivery lift and flow can pass the pneumatic valve open to realize the step less adjustment (the pneumatic pressure adjustment is between 1-7 kgf/cm2 4、 This pump has no rotary parts and no bearing seals. The diaphragm will completely separate the exhausted medium and pump running parts, working medium. The conveyed medium can’t be leaked outside. Thus it will not cause the environmental pollution and human body safety dangerous while exhausting the toxin and flammable or corrosive medium. 5、 No electricity. It’s safe and reliable while using in the flammable and explore places. 6、 It can be soaked in medium. 7、 It’s convenient to use and reliable to work. only open or close the gas valve body while starting or stopping. Even if no medium operation or pausing suddenly for long time because of accident matters, the pump will not be damaged caused by this. once over-loading, the pump will automatically stop and possesses the self-protection function. When the load recovers normally, it also can start automation. 8、 Simple structure and less wearing parts. This pump is simple in structure, installation and maintenance. The medium conveyed by the pump will not touch the matched pneumatic valve and coupling lever etc. not like other kinds pumps, the performance will drop down gradually because of the damages of rotor, gear and vane etc. 9、 It can transmit the adhesive liquid (the viscosity is below 10000centipoise) 10、 This pump needn’t the oil lubricant. Even if idling, it has any influence to the pump. This is a characteristic of this pump.
