(Ecuador stern plate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

stern plate hydraulic cylinder are widely used in Ecuador，because of no need for deceleration device，long service life，smooth movement.So our company has designed stern plate hydraulic cylinder for customers from Ecuador.

Introduction to stern plate hydraulic cylinder:

The coordination of the sliding parts of the stern plate hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

What kind of process is used in the stern plate hydraulic cylinder to make high-quality stern plate hydraulic cylinder products: the body is the main component of the stern plate hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The stern plate hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the stern plate hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the stern plate hydraulic cylinder increases by 25%. If the service life of the stern plate hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. stern plate hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the stern plate hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and stern plate hydraulic cylinder are stuck or the stern plate hydraulic cylinder is blocked. At this time, no matter how to manipulate, the stern plate hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the stern plate hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The stern plate hydraulic cylinder should be used correctly and maintained regularly. The stern plate hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the stern plate hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Before the stern plate hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

Answers to some questions about stern plate hydraulic cylinder:

Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
