Tips for hydraulic cylinder inspection and maintenance

f a hydraulic cylinder is to fully meet user requirements, in addition to design experience and machining accuracy, there is another point that is to be used correctly and maintained regularly. Vent the oil tank before use, adjust the buffer control valve to a reasonable position, check the cleanliness of the oil regularly, clean the dust on the oil tank regularly, and pay attention to waterproofing and fire prevention.

The piston part of the hydraulic cylinder is to extend out of the cylinder in the working state

The hydraulic cylinder is very important to hydraulic machinery. It acts as an executive element in the entire hydraulic machine, and the hydraulic cylinder in the whole process converts hydraulic energy into mechanical energy. With the development and progress of science and technology, the innovation and development of hydraulic cylinder components are very rapid. Actively discover and solve real-life problems, start research, innovation, and then improve production safety and economic efficiency, while fuel consumption.

Causes of unstable operation of hydraulic cylinders

The inside of the hydraulic cylinder is stagnant. The internal parts of the hydraulic cylinder are improperly assembled, deformed, worn, or the shape and position are out of tolerance, and the action resistance is too large, which causes the piston speed of the hydraulic cylinder to vary with the stroke position, causing slippage or crawling. Most of the reasons are due to the poor assembly quality of the parts and the iron filings on the surface due to sintering, which increases the resistance and reduces the speed. If the piston and the piston rod are not concentric or the piston rod is bent, the installation position of the hydraulic cylinder or the piston rod on the guide rail is offset, and the sealing ring is too tight or too loose. The solution is to re-repair or adjust, replace damaged parts, and remove scrap iron.

Components of thin cylinder

Cylinder barrel of thin cylinder: The inner diameter of the cylinder represents the output force of the cylinder. The piston should slide smoothly in the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8um. The inner surface of the steel tube should also be plated with hard chromium to reduce frictional resistance and wear and prevent corrosion. The cylinder barrel is made of high-strength aluminum alloy, brass, and high-carbon steel pipe. Stainless steel tubes for small cylinders. Cylinders with magnetic switches or cylinders used in corrosion-resistant environments should be made of stainless steel, aluminum alloy or brass.

Type of cylinder

A cylindrical metal part that guides the piston to reciprocate linearly in the cylinder. Air expands in the engine cylinder to convert thermal energy into mechanical energy. The gas is compressed by the piston in the compressor cylinder to increase the pressure. Shells of turbines, rotary piston engines, etc. It is also commonly referred to as a "cylinder." Application areas of cylinders: printing (tension control), semiconductors (spot welders, grinding discs), automatic control, robots, etc.
