Hydraulic cylinders (referred to as oil cylinders) are commonly used components in hydraulic systems, and play the role of actuators in hydraulic systems. Other components such as pumps, valves, oil filter accessories, etc. are all supporting services for hydraulic cylinders. The oil cylinder is used as a hydraulic control system. The final actuator plays a very important role in mechanical equipment, so how to choose it correctly. Hydraulic cylinders have become a special concern for enterprises. In general, when we choose hydraulic cylinders, we usually choose hydraulic cylinders based on inner diameter, stroke, operating pressure, and installation type. In fact, in addition to these methods, we can also choose the following methods through other methods. Points are worth noting:
1. When the operating speed of the hydraulic cylinder reaches a certain standard or higher, a hydraulic cylinder with a buffer device must be used, or a deceleration valve must be installed outside the hydraulic cylinder when it reaches a higher speed.
2. It is to carefully select the hydraulic oil droplets of different hydraulic oil and oil seals and use oil hydraulic machine seals of different materials to ensure the life of the hydraulic cylinder.
Do you know how to maintain the hydraulic cylinder? Let's take a look at it together.
1. The hydraulic cylinder and the surrounding environment should be clean, and the oil tank should be sealed to prevent pollution. Pipelines and fuel tanks should be cleaned to prevent falling off iron oxide scale and other debris. Use a lint-free cloth or special paper for cleaning. Do not try twine and adhesives as sealing materials. According to the design requirements of the hydraulic cylinder, pay attention to the change of oil temperature and oil pressure. Unscrew the exhaust bolt to exhaust when no load.
2. There must be no slack in the piping links.
3. The base of the hydraulic cylinder must have sufficient rigidity, otherwise the cylinder will bend upward in a bow shape when pressurized, causing the piston rod to bend.
4. Before installing the hydraulic cylinder into the system, the parameters on the hydraulic cylinder plate should be compared with the parameters at the time of ordering.
5. The center axis of the mobile cylinder with fixed feet should be concentric with the center line of the load force to avoid causing side force, which is easy to wear the seal and damage the piston. When installing the hydraulic cylinder of the moving object, keep the cylinder parallel to the moving direction of the moving object on the guide rail surface, and the parallelism is generally not greater than 0.05mm/m.
