(Switzerland steering cylinder,produced by Hengyu Group）

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

Introduction to steering cylinder:

In the process of using the steering cylinder, sometimes such a problem will occur, the steering cylinder can not act immediately after the instruction of the steering cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil steering cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Regular maintenance of the steering cylinder includes: regular tightening, steering cylinder fastening screws and gland screws, steering cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the steering cylinder once a year. Clean regularly, the steering cylinder is cleaned every other year, and the seals are replaced while cleaning.

How to repair the steering cylinder body when it is damaged: When the steering cylinder has trace deformation and shallow tensile marks, the steering cylinder is repaired by strong honing process. The heavy honing process can repair steering cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the steering cylinder can meet the technical requirements.

Most of the failure of the steering cylinder is because there is a foreign body in the steering cylinder into the failure of the steering cylinder, the most problematic is that it is difficult to determine when the foreign body is into the steering 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 steering cylinder:

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.

The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
