Troubleshooting of the hydraulic motor (1) is not enough output torque ① of the housing bore cylindrical roller with too loose, or cause into the oil chamber of the oil drain back pressure oil chamber (oil chamber) after use and wear, internal leakage volume increases, it should re-processing by brush or roller coupled. ② rotor blade root round wear, internal leakage volume. ③ dirt and roller blades stuck. ④ between the roller and the blade shaft due to poor precision and assembly precision, the roller friction between the outer and the root circle blade large, the film is cut through, resulting in thousands of friction. 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 specifications, including seven as I pump repair products, seven for the 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 tapered piston pump maintenance, the use of two hydraulic piston ring seal, so the efficiency of the hydraulic pump sales, the economy is good. * Use large cone angle tapered roller bearings, easy installation, long service life.
