Hungary hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Hungary reset cylinder,produced by Hengyu Hydraulic Cylinder Factory）
reset cylinder are widely used in Hungary，because of high work efficiency，excellent fatigue and impact resistance，simple structure and reliable operation.So our company has designed reset cylinder for customers from Hungary.
We can not just consider the price and ignore the quality when we purchase the reset cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the reset cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the reset cylinder is not required.
The wear of the hard chromium plating layer of the reset cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
The definition of the minimum stable speed refers to the minimum movement speed of the reset cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the reset cylinder that undertakes different work has different requirements for the minimum stable speed.
The definition of the minimum starting pressure of the reset cylinder refers to the minimum working pressure of the reset cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the reset cylinder parts and the size of the sealing friction.
How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.
What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
