现有隔膜泵的驱动形式大多为传统的机械式曲柄滑块机构，由于由曲柄滑块机构转变来的往复直线运动是一种近似正弦曲线的运动，导致料浆的吸入和排出流量也是一种近似正弦曲线运动，使得隔膜泵的流量脉动性很大，且曲柄滑块机构的运动副间磨损故障是隔膜泵的常见故障，过大的磨损间隙会导致振动和噪声，产生巨大的冲击载荷，加速运动副的磨损，甚至会导致连杆活塞杆折断等，往往给企业造成巨大的经济损失。因此，一种性价比高的新型隔膜泵来代替传统的机械式隔膜泵已成为科技发展的趋势。
    本设计拟采用一种新型的液压缸驱动动力端来代替传统动力端，这种新型的液压驱动隔膜泵利用液压缸直接驱动泵缸活塞。由于采用液压缸驱动隔膜泵的泵缸活塞，简化了减速装置及机械传动装置。因此，新型液压驱动隔膜泵体积比机械式隔膜泵要小很多，主要由动力端部分（定量泵、液控换向阀、先导溢流阀、单向调速阀、电磁阀、液压缸等）和液力端部分（泵头、泵缸、泵缸活塞、吸入阀、排出阀等）组成.这种动力端由大功率的电动机带动定量泵供油，利用PLC控制电磁换向阀实现液压缸的换向，使得活塞在运动过程中，实现匀速往复直线运动（传统设计中，活塞满足正弦曲线运动）

Existing diaphragm pump drive form most of the traditional mechanical slider-crank mechanism, because by the reciprocating linear motion of the slider-crank mechanism shift to is a kind of approximate sine curve movement, leading to the suction and discharge of the slurry flow is also a kind of approximate sine curve movement, make diaphragm pump flow pulsation is large, and the movement of slider-crank mechanism between vice wear failure is common in diaphragm pump failure, excessive wear clearance will lead to vibration and noise, have a huge impact load, accelerated motion pair of wear, even lead to broken connecting rod piston rod, etc., often cause huge economic losses to the enterprise. High performance/price ratio, and as a result, a new diaphragm pump instead of the traditional mechanical diaphragm pump has become the trend of the development of the science and technology.
