Series of quantitative piston pump / motor A2F6.1 series Cline Theorem pumps, motors, with international advanced level of modern products. It can be used as open and closed systems of pumps and motors. The series consists of fourteen nominal size of the hydraulic pump, seven for the I series, seven of II series. I A2F1-4 series products have the same connection port, flanges, shaft extension dimensions. II products with similar specifications I series of products identical flange dimensions. (I) Series Specifications 12 23 28 56 80 107 160 (II) Series Specifications 16 32 45 63 90 125 180A2F6.1 series is developed by A2F1-4 series made, in addition to a series of structural features A2F1-4 outside, still have Structural features the following: * 40 ° large angle, it is more compact size, power per unit weight. * Overall conical plunger, using two piston ring seal, so the efficiency, economy is good. * Use large cone angle tapered roller bearings, easy installation, long service life. Volume pump motor speed control system consists of electro-hydraulic proportional variable displacement pump and quantitative hydraulic motor, whose displacement hydraulic pump by changing the speed of adjustment is achieved, in principle, no throttling, overflow and pressure loss of domestic pump and has high efficiency, low heat generation, high-speed range, the output torque constant advantage, which is widely applied to power or heat a strictly limited hydraulic system. Quantitative variable pump motor diagram: variable pump two oil ports are connected and quantitative motor. Variable pump motor principle amount Volume Timing System. Variable pump input speed pn, mD displacement hydraulic pump motor repair under certain circumstances, by changing the variable displacement pump pD, to adjust the motor output speed mn purposes. Change the variable pump oil discharge direction, can change the steering motor.
