(The Philippines trunnion cylinder,produced by Hengyu Group）

trunnion cylinder are widely used in The Philippines，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed trunnion cylinder for customers from The Philippines.

Introduction to trunnion cylinder:

Do not regularly check the damage of the chrome layer of the trunnion cylinder: completely extend the trunnion cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the trunnion cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the trunnion cylinder seal. Welding slag is strictly prohibited on the surface of the trunnion cylinder.

When the trunnion cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the trunnion cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the trunnion cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

When the control pressure of the hydraulic system is too low, the trunnion cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

The meaning of the trunnion cylinder model marked by the trunnion cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the trunnion cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the trunnion cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about trunnion cylinder:

Why does the tipping bucket cylinder have a cylinder withdrawal problem?
This problem may have a certain relationship with the operation of the driver, the main reasons are the following two situation analysis: 1, the current domestic loader working device is mostly a six-link mechanism, the six-link mechanism in the bucket to the limit position, lift the boom, the rotating bucket cylinder will appear "cylinder pulling" phenomenon, that is, the piston rod of the rotating bucket cylinder will be pulled out. In this case, in order to protect the cylinder, a pressure overload protection valve with large and small cavities is provided on the multi-way valve rotating bucket link (large chamber 18MPa, small chamber 12MPa). 2, before the cylinder is assembled to the whole machine, the cylinder is not limited, the piston rod of the cylinder can be pulled in place before and after, but when it is installed on the whole machine, in order to avoid the cylinder pulling out, the limit switch is installed according to the regulations.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
