Romania pushing cylinder

(Romania pushing cylinder,produced by Hengyu Group)

pushing cylinder are widely used in Romania,because of no transmission clearance,clever hydraulic energy conversion,powerful torque.So our company has designed pushing cylinder for customers from Romania.

Introduction to pushing cylinder:

The difference between the integral pushing cylinder and the split pushing cylinder: The integral pushing cylinder and the split pushing cylinder in the pushing cylinder are two different pushing cylinders, and they are very different. The whole pushing cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split pushing cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and pushing cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

What kind of process is used in the pushing cylinder to make high-quality pushing cylinder products: the body is the main component of the pushing 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 pushing 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 pushing 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 pushing cylinder increases by 25%. If the service life of the pushing 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. pushing 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 pushing 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 pushing cylinder are stuck or the pushing cylinder is blocked. At this time, no matter how to manipulate, the pushing 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 pushing cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The pushing cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the pushing cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the pushing cylinder wall due to the stiffness and the weight of the parts, causing scars.

Most of the failure of the pushing cylinder is because there is a foreign body in the pushing cylinder into the failure of the pushing cylinder, the most problematic is that it is difficult to determine when the foreign body is into the pushing cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

Answers to some questions about pushing cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
