  • Common Faults and Repair Methods of Hydraulic Cylinders

    1. Oil leakage: Hydraulic cylinder oil leakage is common in sealing interfaces such as the joint between the cylinder sleeve and the cylinder head, and the friction surface between the piston rod and the guide sleeve, which usually points to the aging or damage of the sealing element.

  • What are the causes and effects of excessive oil temperature in the hydraulic system?

    Hydraulic systems tend to generate heat during operation, especially when under high load or long-term operation, the hydraulic oil temperature tends to rise. Excessive oil temperature not only affects the performance of the system, but also accelerates the wear of components and even causes early failure of equipment. Therefore, a deep understanding of the factors affecting hydraulic oil temperature, the negative impact of excessive oil temperature on the system, and effective temperature management strategies are essential to ensure efficient and stable operation of the hydraulic system.

  • The development of hydraulic transmission technology

    Hydraulic technology is an emerging technology developed by the principle of hydraulic pressure transmission. Throughout the history of the development of hydraulic transmission technology, it is divided into the following stages:

  • How Is Synchronous Control Of Multiple Hydraulic Cylinders Achieved?

    In modern industrial equipment, hydraulic systems are widely used for a variety of functions such as lifting, propulsion and driving. In these systems, the synchronous operation of multiple hydraulic cylinders is an important part of ensuring the efficient and safe operation of the equipment. The synchronization of hydraulic cylinders can not only improve work efficiency, but also avoid equipment damage caused by inconsistent movement.

  • The Role of Hydraulic Cylinder

    As an efficient energy conversion device, the core function of hydraulic cylinders is to convert hydraulic energy into direct mechanical energy. The following are the main functions of hydraulic cylinders:

  • What are the diagnostic methods for hydraulic cylinder faults?

    A hydraulic cylinder is an executing element in a hydraulic system that converts hydraulic energy into mechanical energy. Its faults can be basically summarized as hydraulic cylinder misoperation, inability to push the load, and piston slip or crawling. The phenomenon of equipment shutdown caused by hydraulic cylinder failure is not uncommon, therefore, the fault diagnosis and maintenance of hydraulic cylinders should be taken seriously.
