液压隔膜计量泵概述

液压隔膜计量泵也叫柱塞隔膜计量泵的一种，是德国巴赫增强型结构设计，该计量泵与被计量介质介质接触部分为隔膜，而驱动部分为液压柱塞。由于隔膜根据被计量介质的不同可选用不同的材质，CSM、FPM、PTFE等，而液压驱动可实现高压计量的需要，所以柱塞隔膜计量泵的使用领域和工矿压力大大提高。
德国巴赫公司的柱塞隔膜计量泵便是这一种类型的计量泵的杰出代表。该计量泵集中了隔膜式计量泵和活塞式计量泵的所有特点，既满足了用户对出口压力的要求（zui高可达100bar），又解决了腐蚀性介质的计量要求。
该计量泵的流量不随压力变化，在工作状态和非工作状态下均可进行0－*的线性调节。
一泵双头设计，使一台泵同时用不同的计量量计量不同介质的应用成为现实，既节省了空间，又降低了成本。
镜面反照式设计，使活塞法兰及计量头在驱动齿轮左右两侧均可自由安装，现场安装灵活。
模块式设计使现场安装及维护变得非常便捷。

柱塞隔膜计量泵工作原理
柱塞隔膜计量泵是由驱动齿轮2带动中空柱塞10往复运动，并通过中空柱塞10中的液压油驱动计量膜片6。中空柱塞10上有一个特殊设计的调节空，使柱塞内外的液压油相同。柱塞10外面套有一可调节的用来关闭调节空的滑环11。当调节孔关闭时，柱塞推动里面的液压油来驱动计量膜片6。在每个行程中，被柱塞推动来驱动计量隔膜的液压油的量，正好等于被计量的介质的量。
计量泵流量的调节，可通过柱塞法兰上的手动旋钮12实现，也可通过变频器、伺服电机等实现。该计量泵的流量不随压力变化的而变化，在静态和工作状态下均可进行0－*的线性调节。调节精度高。其中空柱塞不是固定在电机偏心轮上，在吸入行程中，柱塞被弹簧9反弹回到零位置，从而有效防止了吸入介质在计量头中形成堵塞时给泵造成的损害。
吸入阀8在介质吸入过程中被打开，使介质流入计量头，在加压时吸入阀则切断。
压力阀5在介质加压过程中被打开，而在吸入过程中关闭以防止压出的介质回流入计量头。

Hydraulic diaphragm metering pump inlet hydraulic diaphragm metering pump Germany imports hydraulic diaphragm metering pump Hydraulic diaphragm metering pump
Hydraulic diaphragm metering pump
Hydraulic diaphragm metering pump is also known as a kind of plunger diaphragm metering pump, is the German Bach enhanced structural design, the metering pump is measured medium medium contact part of the diaphragm, and the driving part of the hydraulic piston. Because of the different media according to the measurement of the diaphragm can be made of different material, CSM, FPM, PTFE, and hydraulic drive can realize the need of high voltage measurement, so the use of the field of plunger diaphragm metering pump and mining pressure greatly improved.
Germany Bach company's plunger diaphragm metering pump is an outstanding representative of this type of metering pump. The metering pump has the characteristics of the diaphragm metering pump and the piston type metering pump, which not only meets the requirements of the user to the outlet pressure (up to 100bar), but also solves the measurement requirement of the corrosive medium.
The metering pump flow does not change with pressure, can be used in working and non working state 0* linear regulation.
Double pump design, so that a pump at the same time with a different amount of measurement of different media applications become a reality, not only saves space, but also reduces costs.
Mirror surface design, so that the piston flange and metering head in the drive gear on both sides of the right and left to install, flexible installation site.
Modular design makes installation and maintenance very convenient.
Working principle of plunger diaphragm metering pump
The plunger diaphragm metering pump is driven by a driving gear 2 to drive the hollow plunger piston reciprocating motion, and the diaphragm is driven by the hydraulic oil in the hollow plunger piston 6 to drive the diaphragm to be measured by the hydraulic pressure of the motor. The piston is driven by the hydraulic pressure of the hollow plunger piston, and the metering diaphragm is driven by the hydraulic pressure of the hollow plunger piston 10. Hollow plunger 10 has a special design of the adjustment of the air, so that the same hydraulic fluid inside and outside the plunger. The outer sleeve of the plunger 10 is provided with an adjustable slip ring which is used for closing the adjusting air 11. When the regulating hole is closed, the piston pushes the hydraulic oil inside to drive the metering diaphragm 6. In each stroke, the amount of hydraulic fluid driven by the plunger to drive the metering diaphragm is exactly equal to the amount of the medium being measured.
Metering pump flow adjustment can be achieved through the plunger flange on the manual knob 12, can also be achieved through the inverter, servo motor, etc.. The metering pump with pressure change and change, can be carried out in the static state and 0* linear regulation. High adjustment accuracy. The air piston is not fixed on the eccentric wheel of the motor, and in the suction stroke, the plunger is bounced back to the zero position by the spring 9, so as to effectively prevent the damage to the pump caused by the blockage of the suction medium in the metering head.
The suction valve 8 is opened in the medium suction process so that the medium flows into the metering head.
The pressure valve 5 is opened during the medium pressure, and is closed in the suction process to prevent the pressure of the medium from flowing back into the metering head.
