Basic introduction of boom dual hydraulic cylinder

Double hydraulic cylinder for boom: If the cylinder experiences sliding or crawling (stop and go), please check if there is any sticking inside the hydraulic cylinder. Improper assembly, deformation, wear, or out of tolerance of the internal components of the hydraulic cylinder, coupled with excessive resistance to movement, can cause the piston speed of the hydraulic cylinder to change with different stroke positions, resulting in slippage or crawling. Most of the reasons are due to poor assembly quality of the parts, surface scratches or iron filings generated by sintering, which increase resistance and decrease speed. For example, the piston and piston rod are not concentric or the piston rod is bent, the hydraulic cylinder or piston rod is offset from the guide rail installation position, and the sealing ring is installed too tightly or too loosely. The solution is to repair or adjust again, replace damaged parts, and remove iron filings. At the same time, check whether the lubrication is good or whether the machining of the oil cylinder aperture exceeds the tolerance. Because the piston and cylinder, guide rail and piston rod are all relative to each other, hydraulic cylinders and hydraulic motors are devices that convert the pressure energy of liquids into mechanical energy and output it. The cylinder mainly outputs linear motion and force. There are various forms of hydraulic cylinders, which can be divided into three categories based on their structural characteristics: piston type, plunger type, and swing type. They can also be classified into single acting and double acting according to their mode of action. Piston cylinder, mainly used in machinery such as excavators; Research, such as university structural laboratories. Piston cylinders are commonly used in pressure testing machines, such as Jinan Assay and Sansi's testing machines for material testing. After the installation of the hydraulic cylinder is completed, lubricating grease should be added to the relative moving parts such as the earrings and the middle hinge shaft before trial operation. The commonly used buffering structure of oil cylinders is composed of piston bosses and cylinder head grooves. When the piston moves closer to the cylinder head, it gradually enters the groove and squeezes out the oil in the groove through the gap between the boss and the groove, increasing the return oil resistance and producing a braking effect to achieve buffering. Generally, buffer mechanisms should be selected when the pressure is above 10MP. How to solve the problem of stuck oil cylinder valve core or blocked valve hole: When the flow valve or directional valve core is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or malfunction. At this time, the contamination of the oil should be checked; Check if dirt or gum deposits are stuck in the valve core or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the oil tank, and replace the hydraulic medium.

Maintenance and related issues of boom dual hydraulic cylinder

• Please advise on the locking force of the oil cylinder
  Personal understanding: 1 The locking force of a hydraulic cylinder refers to the external force that the cylinder can withstand when both outlets are closed. If no overflow valve is installed, this force is the product of the piston area of the hydraulic cylinder and the maximum working pressure of the hydraulic cylinder. Beyond this force, there is a chance for the hydraulic cylinder to be damaged. The maximum thrust of the hydraulic cylinder should be considered together with the output pressure of the oil pump. If the hydraulic cylinder can be used for 250 bar and the maximum working pressure of the hydraulic system is 200 bar, the maximum thrust of this hydraulic cylinder will be less than the locking force of the hydraulic cylinder.

• What is the reason why the hydraulic cylinder of a manual forklift cannot be lifted?
  Manual hydraulic forklifts often have the problem of not being able to press, and there are several reasons for this. We will analyze them separately: manual hydraulic handling vehicles and manual hydraulic stacker trucks. Manual hydraulic handling vehicles: 1) no hydraulic oil, 2) insufficient oil purity, 3) adjusting bolts too close or adjusting screws too tight, causing the valve to always be open, 4) air removal methods in the hydraulic cylinder: 1) refueling, 2) oil change, 3) air removal. Manual hydraulic stacker trucks, also known as manual lift trucks, 1) insufficient oil volume, 2) impurities in the hydraulic oil, making the one-way valve unable to close. Elimination methods: 1) add enough hydraulic oil, 2) remove the hydraulic cylinder, unscrew the bottom plate screws, and clean the bottom plate
• Hairun hydraulic press teaches you how to correctly disassemble the oil cylinder
  (1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the oil pipe joint connected to the oil cylinder is loosened, the high-pressure oil in the circuit will quickly spray out. When unloading the hydraulic circuit of the hydraulic press, the handwheel or pressure regulating screw at the relief valve should be loosened first to unload the pressure oil, and then the power supply or power source should be blocked to stop the operation of the hydraulic equipment. (2) When disassembling, precautions should be taken to prevent damage to the top threads of the piston rod, the oil port threads, the surface of the piston rod, and the inner wall of the cylinder liner. In order to prevent the piston rod and other slender components from twisting or deforming, use wooden pads to support and balance them during placement. (3) When disassembling, it should be done in order. Due to the different layouts and sizes of hydraulic cylinders in various hydraulic presses, the disassembly sequence is also slightly different
