(Sri Lanka trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the trunnion cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

The definition of the minimum starting pressure of the trunnion cylinder refers to the minimum working pressure of the trunnion cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the trunnion cylinder parts and the size of the sealing friction.

In order to ensure the service life of the trunnion cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

The trunnion cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the trunnion cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The trunnion cylinder is basically composed of trunnion cylinder and trunnion cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Answers to some questions about trunnion cylinder:

Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.

Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
