Basic Introduction to Rotating Oil Cylinder

Rotating oil cylinder: Precautions for oil cylinder installation: Before installing the hydraulic cylinder into the system, the parameters on the hydraulic cylinder label should be compared with the parameters at the time of ordering. The base of the hydraulic cylinder must have sufficient rigidity, otherwise when pressurized, the cylinder barrel will arch upwards, causing the piston rod to bend. When using the oil cylinder, it is necessary to prevent internal leakage of the hydraulic cylinder. Internal leakage of hydraulic cylinders includes leakage caused by excessive wear of the hydraulic cylinder body seal, piston rod and seal cover seal, and piston seal. The reason for the leakage of the piston rod and sealing cover seal is due to the wrinkling, squeezing, tearing, wear, aging, deterioration, deformation, etc. of the seal. At this time, a new seal should be replaced. Selection of oil cylinder and hydraulic station: Select the type and structural form of hydraulic cylinder according to the action requirements of the host. Based on the external load forces borne by the hydraulic cylinder, such as gravity, external mechanism motion friction, inertia force, and working load, determine the load variation law and the required power value of the hydraulic cylinder at each stage of the stroke. Determine the diameter of the piston and piston rod based on the working load of the hydraulic cylinder and the selected oil working pressure. Determine the flow rate of the hydraulic pump based on the movement speed of the hydraulic cylinder, the diameter of the piston and piston rod. Inspection and maintenance of oil cylinder buffer valve: For valve buffer hydraulic cylinders, it is important to focus on checking the wear of the buffer valve core and seat. Once increased wear and seal failure are detected, replacement should be carried out. Abrasives can also be used to repair the valve core and valve seat by grinding them together. During the installation of the oil cylinder body, do not allow foreign objects to enter. The place where installation operations are carried out has poor conditions, and foreign objects can enter unconsciously. Therefore, the surrounding area of the installation site must be cleaned up, especially the place where the parts are placed must be cleaned thoroughly to avoid any dirt.

Reference price for rotating oil cylinder

The cost of rotating oil cylinders is determined by factors such as system pressure, whether pressure maintenance is required, temperature requirements, and frequency of use. The thrust size and price range vary, with common brands of rotating oil cylinders costing between 700/yuan and 30000/yuan.

Maintenance and related issues of rotating oil cylinder

• Urgent, there is a sound coming from the hydraulic cylinder of the excavator boom. I don't know what the reason is
  The hydraulic cylinder of a hydraulic excavator includes three main parts: boom hydraulic cylinder, boom hydraulic cylinder, and bucket hydraulic cylinder, with four major hydraulic cylinders. The sound of the boom hydraulic cylinder may be due to wear of the cylinder body liner, piston rod liner, and shaft pin. The main reason is poor lubrication, followed by improper clearance during assembly. Countermeasure: (1) Strictly implement the lubrication of each axle pin at least once every 8 hours during the initial 100 hours of use and harsh working conditions of the excavator; Under other operating conditions, it is required to lubricate each shaft pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Strict adherence to assembly inspection standards and procedures is required when assembling and replacing various shaft pins and bushings
• What are the hazards of hydraulic cylinder overheating and how to solve them.
  Excessive oil temperature can cause the sealing ring to fail and the distance between oil molecules to increase, resulting in bubbles. The ultimate result is oil leakage. To find the root cause of the oil leakage, if it is summer, there is no way but to manually water the oil tank to cool it down. If there are vibrating parts in the entire hydraulic system, it can also cause excessive oil temperature. In addition, overloading can also affect the rapid rise of oil temperature, so please follow the rules for driving
• What should be the safety factor for a 25MPa hydraulic cylinder wall thickness?
  The safety factor n can be taken as the allowable stress of the material of the 3-cylinder cylinder [s]=sb/n δ/D=0.08~0.3 hydraulic cylinder wall thickness δ=PMAX * D/(2.3 [s] -3PMAX) δ/D ≤ 0.08 hydraulic cylinder wall thickness δ=PMAX * D/2 [s] P ＜ 16MPa, Pmax=1.5Pn; P>16MPa, Pmax=1.25Pn. Cold drawn or honed pipes are better!
• Is there a risk of using a 40 cylinder oil cylinder when the weight of the slider is 35 pounds and the stroke is 55mm?
  The maximum output force of a 40 cylinder hydraulic cylinder can reach 2 tons. Can you estimate if it is enough? Also, the problem of mechanism jamming is not related to the size of the power source. Reasonable structural design and good machining and assembly accuracy are the key.
