(Angola roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

roller press hydraulic cylinder are widely used in Angola，because of long service life，smooth movement，high work efficiency.So our company has designed roller press hydraulic cylinder for customers from Angola.

Introduction to roller press hydraulic cylinder:

In recent years, the processing process of the roller press hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Do not regularly check the damage of the chrome layer of the roller press hydraulic cylinder: completely extend the roller press hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the roller press hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the roller press hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the roller press hydraulic cylinder.

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

When the roller press hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the roller press hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

Answers to some questions about roller press hydraulic cylinder:

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.

How to distinguish the bucket cylinder from the bucket rod cylinder?
It can be distinguished according to its installation and connection: one end of the bucket cylinder is connected with the bucket; The rod cylinder is not connected to the bucket. The bucket refers to the bucket installed on the excavator. According to the working mode, it is divided into backhoe bucket and shovel bucket, the backhoe bucket is commonly used. The boom and bucket rod are working device of the excavator, usually called the big arm and the forearm, which are mainly used to control the digging and loading of the bucket. The arm connected to the frame is longer, so it is commonly known as the big arm, and its term is called the boom. The arms connected to the digging bucket are smaller, so they are commonly known as the lower arms, and the term is called the bucket rod, so they are commonly known as the big lower arms.
