Dominica trunnion cylinder

(Dominica trunnion cylinder,produced by Hengyu Group)

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

Introduction to trunnion cylinder:

There are some honeycomb holes in the inner wall of the trunnion cylinder, piston or piston rod surface. How is this formed? When we repair the trunnion cylinder, we can see that there are some honeycomb holes on the inner wall of the trunnion cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the trunnion cylinder is targeted to prevent. Is very necessary.

trunnion cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the trunnion cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the trunnion cylinder. c. The trunnion cylinder seal is extruded, if the O-ring is obviously extruded at the trunnion cylinder seal, replace the trunnion cylinder seal.

When the trunnion cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the trunnion cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

When producing oil trunnion cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about trunnion cylinder:

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.

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.
