The hydraulic cylinder is the performing element of the hydraulic system, and its operation failure is related to the whole system in addition to the cause of the product itself. Therefore, when cleaning up the operation failure of the product, we should carefully investigate its symptoms, select the method of logical reasoning and force one by one, carefully analyze the cause of the failure from the outside to the inside, and then clean up the method to avoid blind large-scale disassembly and unloading. Among the many causes of product operation failure, improper equipment, application and protection are the causes of the failure. Such problems are not discussed here. The following small series will explain to you the typical operation failure - the poor product action and systematic analysis.

Most of them are: the hydraulic cylinder can't act, the action is not agile (there is blocking phenomenon) and the movement crawls.

In addition to the following basic conditions for the selection of products: 1. Inner diameter 2. Stroke 3. Application pressure 4. Equipment mode, the following conditions need to be selected: A. when the actuating speed of the product reaches above a certain specification after the product is loaded, it is necessary to select a buffered product. Or when the higher speed is reached, the deceleration valve must be installed outside the product. B. Carefully select hydraulic oil and oil seal. Different hydraulic oils are suitable for oil seals with different raw materials to ensure the longevity of products.

The failure of the hydraulic cylinder often occurs on the finished products. When clearing this fault, first find the cause from the outside of the product: whether the resistance of the moving parts is too large, and whether there are conditions such as jamming, wedging or resisting other parts; Whether the oil inlet pressure reaches the specified value. After the external factors are eliminated, further check the reasons in the product and adopt the corresponding elimination methods.
