El Salvador hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder

(El Salvador trunnion cylinder,produced by Hebei Hengyu company）

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

Introduction to trunnion cylinder:

The daily inspection of the trunnion cylinder includes: checking the connection of the trunnion cylinder and the pipe joint for leaks. Check the trunnion cylinder rod for leaks. Check the trunnion cylinder connection for leaks. When the trunnion cylinder moves, the work is normal and smooth. Whether the trunnion cylinder has internal leakage.

The viscosity of the working oil used in the trunnion cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

The trunnion cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the trunnion cylinder, bite. Elimination method: When installing the trunnion cylinder, ensure that the axis position of the trunnion cylinder is consistent with the direction of movement; Make the load borne by the trunnion cylinder as far as possible through the trunnion cylinder axis, to avoid the phenomenon of eccentricity.

When the trunnion cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the trunnion cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

Answers to some questions about trunnion cylinder:

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
