Ghana rolling mill cylinder

(Ghana rolling mill cylinder,produced by Hengyu Hydraulic Co., Ltd)

rolling mill cylinder are widely used in Ghana,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed rolling mill cylinder for customers from Ghana.

Introduction to rolling mill cylinder:

When installing the rolling mill cylinder pipe, the pipe should be cleaned after installation, and should not pass through the rolling mill cylinder block, and the by-pass pipe must be installed in front of the oil port of the rolling mill cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the rolling mill cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the rolling mill cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

The internal leakage of the rolling mill cylinder is an important indicator to measure the quality of the rolling mill cylinder: the internal leakage of the rolling mill cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the rolling mill cylinder, so that the rolling mill cylinder can not accurately and stably stop in a certain position of the rolling mill cylinder, so it is one of the main indicators of the rolling mill cylinder.

The machining accuracy of the rolling mill cylinder depends on the level of equipment, production technology and testing means. rolling mill cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

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

Answers to some questions about rolling mill cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

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.
