The hydraulic cylinder often has a jumping and stopping movement state during operation, which we call creeping phenomenon. This phenomenon is especially easy to occur at low speed, which is also one of the main faults of hydraulic cylinder.To solve the problem of hydraulic cylinder creep, we must study the cause of this phenomenon. After summarizing, we found that the cause for hydraulic cylinder creep not only have something to do with the hydraulic cylinder itself and also related to other factors outside the cylinder. Let’s talk about it today. Internal causes of hydraulic cylinder creep failure ① There is residual air in the cylinder, and the working medium forms an elastic body. Troubleshooting method: Fully exhaust the air; check whether the diameter of the hydraulic pump suction pipe is too small, and the suction pipe joint should be well sealed to prevent the pump from sucking air. ② The sealing friction is too large. Troubleshooting method: The piston rod and the guide sleeve are matched with H8/f8, and the depth and width of the sealing ring groove are strictly made according to the dimensional tolerance; if a V-shaped sealing ring is used, adjust the sealing friction to a moderate degree. ③ The sliding parts

In hydraulic systems, hydraulic cylinders are widely used in a variety of scenarios such as heavy lifting operations, propulsion operations, and driving operations. 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 the efficiency of operations, but also avoid equipment damage caused by inconsistent movement. This article will explore in depth the principles of the synchronous movement of multiple hydraulic cylinders, common synchronization methods, technical challenges, and precautions during operation. 1. Working principle of hydraulic cylinder synchronization Hydraulic cylinder synchronization means that multiple cylinders extend or retract at the same speed and force at the same time. The core lies in the uniform distribution of hydraulic fluid and the precise control of pressure. The realization of synchronous operation depends on the following key factors: Fluid dynamics: The basic principle of the hydraulic system is to use the incompressibility of the liquid to convert pressure into power. The synchronous movement of the cylinder is achieved by controlling the direction and flow of the liquid flow. Load balancing: When multiple hydraulic cylinders share the load, ensure that each

The project will utilize the Japanese railway system that uses energy-efficient and reliable trains.  RIVERLAKE supplied a pile load testing system consisting of 2 units of 1000-ton hydraulic cylinders and 1 unit PLC-controlled electric hydraulic power unit. The system will perform pile load testing work up to 1569 tons in the NSCR Extension Project. RIVERLAKE PLC controlled hydraulic jacking system is designed for pile load tests up to 2000 tons where the load is to be applied in different stages and displayed accurately in real-time. The plc pile load test jacking system provides 6 default tonnage options, user can preset the loading tonnage and holding period of time for each option. During pile load test operation, the whole process is run automatically, just select one of the preset tonnages and press the auto-run button. the hydraulic jack will raise to its full stroke, upon reaching the preset load, the jacking system will stop automatically and hold the pressure for the preset period of time.
