(Spain automatic reversing cylinder,produced by Hengyu Group）

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

Introduction to automatic reversing cylinder:

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

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

When the automatic reversing cylinder needs to be stored for a period of time, please follow the recommended methods: The automatic reversing cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the automatic reversing cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil automatic reversing cylinder should not be in direct contact with water vapor for a long time. The automatic reversing cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the automatic reversing cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the automatic reversing cylinder Before working, the automatic reversing cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the automatic reversing cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When the initial action of the automatic reversing 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 automatic reversing 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.

Answers to some questions about automatic reversing cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
