进口气动双隔膜泵原理特点

进口气动双隔膜泵是一种新型输送机械，采用压缩空气为动力源，对于各种腐蚀性液体，带颗粒的液体，高粘度、易挥发、易燃、剧毒的液体，均能予以抽光吸尽。德国托马斯(Thomas)气动双隔膜泵广泛应用于各行业，产品质量深受好评。该泵不需灌引水，既能抽送流动的液体，又能输送一些是易流动的介质，吸程高、扬程可调（0-50米）气源压力只须大于1kg/cm2即能工作，绝对防火防爆，具有潜水泵、自吸泵、杂质泵、屏蔽泵、泥浆泵的一切功能和输送机械的许多特点。
工作原理
气动双隔膜泵采用压缩空气、氮气或天然气作为动力。主定向（气动）控制阀将压缩空气分配至气体腔室，向隔膜的内表面上施加均匀压力。同时排出的气体从泵另一侧后方通过气阀组件导向端口排出。气动双隔膜泵内腔气体压力超过液体腔压力，隔膜连杆来回移动，在一侧进行排放，在另一侧进行吸入。排放和吸入液体的方向由止回阀（球阀或片状阀）的方向控制。吸入行程使泵执行吸入。吸入行程可降低舱室压力，增加腔室体积。从而生成大气压力压差，推动液体经过吸入管道，穿过吸入侧止回阀，流入外部液体腔。吸入侧行程还可启动泵的往复（移位、行程或循环）运动。气动双隔膜泵通过行程机械拉动吸入隔膜的移动气动双隔膜泵的内板与对准的驱动柱塞发生接触，移动导向阀芯。导向阀激活后，便向主定向气阀的另一端发出压力信号，气动双隔膜泵使压缩空气方向改向内部腔室的另一侧如此反复运动完成介质的连续输送。
产品特点
1、气动隔膜泵不会产生电火花：气动隔膜泵不用电力作动力，接地后又防止了静电火花。
2、不会过热：压缩空气作动力，在排气时是一个膨胀吸热的过程，气动泵工作时温度是降低的，无有害气体排出
3、可以通过含颗粒液体：因为容积式工作且进口为球阀，所以不容易被堵。
4、对物料的剪切力极低：工作时是怎么吸进怎么吐出，所以对物料的搅动最小，适用于不稳定物质的输送.
5、流量可调节，可以在物料出口处加装节流阀来调节流量。
6、气动隔膜泵具有自吸的功能。
7、可以空运行，而不会有危险。
8、可以潜水工作。
9、气动隔膜泵可以输送的流体极为广泛，从低粘度的到高粘度的，从腐蚀性得到粘稠的。
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 Thomas (Thomas) 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.

9, pneumatic diaphragm pump can transport the fluid is very wide, from low viscosity to high viscosity, from the corrosive get sticky.
