進口氣動雙隔膜泵是一種新型輸送機械，采用壓縮空氣為動力源，對于各種腐蝕性液體，帶顆粒的液體，高粘度、易揮發、易燃、劇毒的液體，均能予以抽光吸盡。德國漢克(HANK)氣動雙隔膜泵廣泛應用于各行業，產品質量深受好評。該泵不需灌引水，既能抽送流動的液體，又能輸送一些是易流動的介質，吸程高、揚程可調（0-50米）氣源壓力只須大于1kg/cm2即能工作，絕對防火防爆，具有潛水泵、自吸泵、雜質泵、屏蔽泵、泥漿泵的一切功能和輸送機械的許多特點。

工作原理

氣動雙隔膜泵采用壓縮空氣、氮氣或天然氣作為動力。主定向（氣動）控制閥將壓縮空氣分配至氣體腔室，向隔膜的內表面上施加均勻壓力。同時排出的氣體從泵另一側后方通過氣閥組件導向端口排出。氣動雙隔膜泵內腔氣體壓力超過液體腔壓力，隔膜連桿來回移動，在一側進行排放，在另一側進行吸入。排放和吸入液體的方向由止回閥（球閥或片狀閥）的方向控制。吸入行程使泵執行吸入。吸入行程可降低艙室壓力，增加腔室體積。從而生成大氣壓力壓差，推動液體經過吸入管道，穿過吸入側止回閥，流入外部液體腔。吸入側行程還可啟動泵的往復（移位、行程或循環）運動。氣動雙隔膜泵通過行程機械拉動吸入隔膜的移動氣動雙隔膜泵的內板與對準的驅動柱塞發生接觸，移動導向閥芯。導向閥激活后，便向主定向氣閥的另一端發出壓力信號，氣動雙隔膜泵使壓縮空氣方向改向內部腔室的另一側如此反復運動完成介質的連續輸送。

產品特點

1、氣動隔膜泵不會產生電火花：氣動隔膜泵不用電力作動力，接地后又防止了靜電火花。

2、不會過熱：壓縮空氣作動力，在排氣時是一個膨脹吸熱的過程，氣動泵工作時溫度是降低的，無有害氣體排出

3、可以通過含顆粒液體：因為容積式工作且進口為球閥，所以不容易被堵。

4、對物料的剪切力極低：工作時是怎么吸進怎么吐出，所以對物料的攪動最小，適用于不穩定物質的輸送.

5、流量可調節，可以在物料出口處加裝節流閥來調節流量。

6、氣動隔膜泵具有自吸的功能。

7、可以空運行，而不會有危險。

8、可以潛水工作。

9、氣動隔膜泵可以輸送的流體極為廣泛，從低粘度的到高粘度的，從腐蝕性得到粘稠的。

Pneumatic double diaphragm pump is a new type of conveying machinery, using compressed air as the power source, for a variety of corrosive liquids, with liquid particles, high viscosity, volatile, flammable, highly toxic liquid, can be pumping Exhausted. Germany Hank (HANK) pneumatic double diaphragm pump is widely used in various industries, product quality acclaimed. The pump does not need to irrigate the water, both pumping the flow of liquid, but also transport some easy flow of the medium, suction high, adjustable head (0-50 m) air pressure only need to be greater than 1kg / cm2 that can work, Absolute fire protection, with a submersible pump, self-priming pump, impurity pump, shielding pump, mud pump all the features and many characteristics of the conveyor machinery.

Working principle

Pneumatic double diaphragm pump with compressed air, nitrogen or natural gas as a power. The main directional (pneumatic) control valve distributes the compressed air to the gas chamber and applies a uniform pressure to the inner surface of the diaphragm. While the discharged gas is discharged from the rear side of the pump through the valve assembly guide port. Pneumatic double diaphragm pump chamber gas pressure exceeds the liquid chamber pressure, diaphragm link back and forth movement, in one side of the discharge, in the other side of the suction. The direction of the discharge and suction of the liquid is controlled by the direction of the check valve (ball valve or sheet valve). The suction stroke causes the pump to perform inhalation. The suction stroke reduces the chamber pressure and increases the chamber volume. Thereby generating atmospheric pressure differential pressure, to promote the liquid through the suction pipe, through the suction side of the check valve, into the external liquid chamber. The suction side travel also initiates the reciprocating (displacement, stroke or cycle) movement of the pump. Pneumatic double diaphragm pump Moves the suction diaphragm through the stroke Mechanical movement The diaphragm of the double diaphragm pump comes into contact with the aligned drive plunger and moves the pilot spool. When the pilot valve is activated, it will send a pressure signal to the other end of the main directional valve. The pneumatic double diaphragm pump will reverse the direction of the compressed air to the other side of the internal chamber so that the continuous conveyance of the medium is completed.

Features

1, pneumatic diaphragm pump does not produce spark: Pneumatic diaphragm pump without power for power, ground and then prevent the static spark.

2, not overheating: compressed air for power, in the exhaust is a process of expansion and endothermic, pneumatic pump work is the temperature is reduced, no harmful gas discharge

3, can be through the liquid containing particles: because the volume of work and import for the ball valve, it is not easy to be blocked.

4, the material shear force is very low: how the work is sucked into how to spit out, so the smallest material agitation, for the transport of unstable substances.

5, the flow can be adjusted, you can install the throttle at the material exit to adjust the flow.

6, pneumatic diaphragm pump with self-priming function.

7, you can run empty, and not dangerous.

8, can dive work.
