Basic introduction of front and rear leg oil cylinders

Front and rear leg oil cylinders: Inspection and maintenance of the 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. What are the most important components in the oil cylinder structure and how to disassemble and assemble them:

The piston, piston rod, and sealing device of the oil cylinder are essential. If one of them is missing, the oil cylinder is no longer called an oil cylinder. In addition, there are buffer devices and discharge devices. Although these two devices are the main components of the oil cylinder, they can be changed according to different situations. Since the oil cylinder is assembled from multiple components, necessary matters cannot be avoided during disassembly. Before disassembling the oil cylinder, make sure that the liquid has been pressurized in the circuit. If this is not done or checked, the liquid will splash out during the disassembly process. Also, be sure to cut off the power before proceeding with the operation.

Disassembly should be carried out in order, and different types of oil cylinders can improve their service life. It is necessary to maintain the normal clearance between the joint surfaces of each hydraulic component. When manufacturing or repairing the main components of hydraulic cylinders (such as cylinder bodies, piston rods, etc.), they should be assembled according to the lower tolerance limit of the assembly dimensions, which can effectively reduce the occurrence of cavitation. If the hydraulic components have already experienced cavitation, only metallographic sandpaper polishing technology can be used to remove the pitting and surface carbon deposits caused by cavitation. Ordinary fine sandpaper should not be used for polishing treatment. To ensure the service life of the hydraulic cylinder, effective filtration must be set up in the hydraulic system to prevent pollution. The cleanliness of the oil should comply with the ISO 4406 standard, and the quality of the filtration should also comply with the corresponding ISO standards. The level of the filter is required to be implemented according to the actual working conditions of the system, but the minimum requirement is not lower than level 19/15 in ISO4406, which is level 24 μ (β 10 ≥ 75) in ISO4572.

Reference price for front and rear leg oil cylinders

• The price of front and rear leg oil cylinders is determined by factors such as usage environment, technical requirements, stroke range, and operating speed. Whether synchronization is required or not varies, and the factory price also varies. The cost of common brands of front and rear leg oil cylinders ranges from 1000/yuan to 4400/yuan.
  Maintenance and related issues of front and rear leg oil cylinders
• How to calculate hydraulic cylinder pressure, how much pressure can support how much weight
  To calculate the pressure of a hydraulic cylinder, you must know the inner diameter of the cylinder barrel. If you are lifting a heavy object with a piston rod, it should be: hydraulic cylinder (without piston rod end) pressure=load (4000N) ÷ {(π/4) X square of cylinder diameter (mm) '. This is not related to the piston rod diameter, but only to the stability of the hydraulic cylinder. The pressure inside the hydraulic cylinder should be p=F/S=400 × 10/(3.14 × (0.5 × 25) × (0.5 × 25))=8.15MPa, which means that to complete this action, you need to provide at least this high pressure Calculate the pump based on this Is there no requirement for speed? What about other dimensions of the cylinder.
• Is there a problem with the bucket oil cylinder being pulled out?
  This issue may be related to the driver's operation, and the main reasons can be analyzed in the following two situations: 1. Currently, most of the working devices used in domestic loaders are six link mechanisms. When the bucket is flipped down to the limit position, the boom is lifted and the bucket cylinder will experience a phenomenon of "pulling out", that is, the piston rod of the bucket cylinder will be pulled out. In this case, in order to protect the oil cylinder, pressure overload protection valves with large and small chambers (large chamber 18MPa, small chamber 12MPa) are installed on the multi way valve rotary bucket connection, and the small chamber is the tipping bucket chamber; 2. Before being assembled onto the entire machine, the oil cylinder has no limit, and the piston rod of the oil cylinder can be pulled in place forward and backward. However, when installing the oil cylinder onto the entire machine, in order to avoid
• Can the combination of PLC, frequency converter, motor, pump, solenoid valve, and oil cylinder control the position accuracy of the oil cylinder?
  Please consider a few issues: 1. Hydraulic oil can be compressed, and it has elasticity like a spring. So, in general hydraulic servo systems, valve control is much more precise than pump control. Because the valve can be installed very close to the hydraulic cylinder, or even on the hydraulic cylinder, but the pump must pass through the oil pipe before entering the hydraulic cylinder, which has a long distance, greatly reducing the rigidity of the system and increasing the difficulty of control. 2. The quantitative pump first has leakage and also has 10% -20% flow pulsation. Secondly, unfortunately, the leakage of the pump is related to pressure and exhibits nonlinear characteristics. So at startup, under low speed and high pressure, the pump may not even have
