(Holland yg series hydraulic cylinder,produced by Hebei Hengyu company）

yg series hydraulic cylinder are widely used in Holland，because of excellent temperature resistance，no transmission clearance，simple structure and reliable operation.So our company has designed yg series hydraulic cylinder for customers from Holland.

Introduction to yg series hydraulic cylinder:

The machining accuracy of the yg series hydraulic cylinder depends on the level of equipment, production technology and testing means. yg series hydraulic 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 main role of the yg series hydraulic cylinder: the yg series hydraulic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the yg series hydraulic cylinder realizes reciprocating motion. The structure of the yg series hydraulic cylinder has three categories: piston yg series hydraulic cylinder, plunger yg series hydraulic cylinder, swing yg series hydraulic cylinder, piston yg series hydraulic cylinder and plunger yg series hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing yg series hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the yg series hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The yg series hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

When the piston speed of the yg series hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the yg series hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The piston rod of the yg series hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about yg series hydraulic cylinder:

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
