Sudan steel mill cylinder

(Sudan steel mill cylinder,produced by Hebei Hengyu company)

steel mill cylinder are widely used in Sudan,because of clever hydraulic energy conversion,simple structure and reliable operation,powerful torque.So our company has designed steel mill cylinder for customers from Sudan.

Introduction to steel mill cylinder:

The steel mill cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure steel mill cylinder can use 20 steel pipe, and the high pressure steel mill cylinder can use 45 steel pipe.

When the steel mill cylinder needs to be stored for a period of time, please follow the recommended methods: The steel mill cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the steel mill cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil steel mill cylinder should not be in direct contact with water vapor for a long time. The steel mill cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the steel mill cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the steel mill cylinder Before working, the steel mill cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the steel mill cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

After chrome plating of the piston rod of the steel mill cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The difference between the plunger steel mill cylinder and the piston steel mill cylinder is that the piston in the steel mill cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type steel mill cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about steel mill cylinder:

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
