Vietnam swager cylinder

(Vietnam swager cylinder,produced by Hengyu Hydraulic Cylinder Factory)

swager cylinder are widely used in Vietnam,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed swager cylinder for customers from Vietnam.

Introduction to swager cylinder:

The main role of the swager cylinder: the swager 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 swager cylinder realizes reciprocating motion. The structure of the swager cylinder has three categories: piston swager cylinder, plunger swager cylinder, swing swager cylinder, piston swager cylinder and plunger swager cylinder to achieve reciprocating linear motion, output speed and thrust, swing swager cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the swager cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The swager cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

swager cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the swager cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

When the initial action of the swager cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the swager cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

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

Answers to some questions about swager cylinder:

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
