Cameroon hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder

(Cameroon trunnion cylinder,produced by Hebei Hengyu company）

trunnion cylinder are widely used in Cameroon，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed trunnion cylinder for customers from Cameroon.

Introduction to trunnion cylinder:

The definition of the minimum stable speed refers to the minimum movement speed of the trunnion cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the trunnion cylinder that undertakes different work has different requirements for the minimum stable speed.

The trunnion cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the trunnion cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the trunnion cylinder wall due to the stiffness and the weight of the parts, causing scars.

If the seal of the trunnion cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and trunnion cylinder, and the phenomenon of "pulling the trunnion cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

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.

Answers to some questions about trunnion cylinder:

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
