steering cylinder are widely used in India，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed steering cylinder for customers from India.

Introduction to steering cylinder:

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

steering cylinder body inspection: The inner surface of the steering cylinder and the piston seal are the main factors causing the leakage in the steering cylinder, if the steering cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the steering cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The pressure of the sliding surface of the steering cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the steering cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

The machining accuracy of the steering cylinder depends on the level of equipment, production technology and testing means. steering 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.

Answers to some questions about steering cylinder:

PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
