Reasons for failure of hydraulic cylinders: In recent years, the maintenance mode of hydraulic cylinders in most enterprises has remained in the category of simple replacement, that is, only replacing seals and performing simple grinding and cleaning, even for severely damaged parts. However, after simple maintenance, the hydraulic cylinder has a short service life, a high failure rate and high maintenance costs. It can be seen that replacement is not a core measure of maintenance management. Enterprises should first analyze the failure reasons of the hydraulic system in essence to ensure the effective operation of the equipment to the greatest extent. ...

The difference between a hydraulic motor and a hydraulic pump: 1. A hydraulic pump is a conversion device that converts the mechanical energy of a motor into hydraulic energy, and outputs a flow rate and pressure, hoping for high volumetric efficiency; a hydraulic motor is a device that converts the pressure energy of a liquid into mechanical energy Output torque and speed are expected to have high mechanical efficiency. Therefore, the hydraulic pump is an energy device, and the hydraulic motor is an actuator. 2. The steering of the output shaft of the hydraulic motor must be able to rotate forward and reverse, so its structure is symmetrical; and some hydraulic pumps (such as gear pumps, vanes ...

1. Power part-converts the mechanical energy of the prime mover into pressure energy (hydraulic energy) of the oil. For example: hydraulic pump. 2. Execution part-convert the oil pressure energy input by the hydraulic pump into mechanical energy that drives the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control section-used to control and adjust the pressure, flow and flow direction of the oil. For example: pressure control valve, flow control valve and directional control valve. 4. Auxiliary parts-connect the first three parts together to form a system, starting to store oil ...
