(Britain pile driver hydraulic cylinder,produced by Hebei Hengyu company）

pile driver hydraulic cylinder are widely used in Britain，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed pile driver hydraulic cylinder for customers from Britain.

Introduction to pile driver hydraulic cylinder:

The assembly work of the pile driver hydraulic cylinder has a great impact on the quality of the pile driver hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

The pile driver hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the pile driver hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The pile driver hydraulic cylinder is basically composed of pile driver hydraulic cylinder and pile driver hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

The pile driver hydraulic cylinder should be vented: when the pile driver hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the pile driver hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the pile driver hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the pile driver hydraulic cylinder, the oil is best entered and discharged from the highest point of the pile driver hydraulic cylinder. pile driver hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

If the seal of the pile driver hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and pile driver hydraulic cylinder, and the phenomenon of "pulling the pile driver hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

Answers to some questions about pile driver hydraulic cylinder:

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each 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) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.
