Shandong Hydraulic Madam introduced the principle of hydraulic motor drive. The active axis of the hydraulic motor is connected to the active axis of the pump (coaxial). When the hydraulic motor is rotated, the pump rotates. Hydraulic pumps and hydraulic motors are hydraulic elements that can be reversed. Entering working liquid to any kind of hydraulic pump can turn it into a hydraulic motor condition; otherwise, when the main axis of the hydraulic motor is rotated by the external torque, it also It can be turned into a hydraulic pump. Because they have the same basic structural elements, they can be closed and can change the volume and corresponding oil distribution institutions.
There are still many differences between the Shandong Hydraulic Motor Company that there are still many differences between the same type of hydraulic motor and the hydraulic pump. Because the working conditions of hydraulic motors and hydraulic pumps are different, their performance requirements are not the same. First of all, hydraulic motors should be able to be positive and reversed, so they are required to be symmetrical. There are certain requirements for stable speed. Therefore, it usually uses rolling bearings or static pressure sliding bearing; secondly, hydraulic motors do not have to have self -a suction capacity because they work under the conditions of input pressure oil, but they need a certain initial sealing to provide the necessary start torque. It is because of these differences that hydraulic motors and hydraulic pumps are similar in structure, but they cannot be reversed.
