(Malaysia trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

How to determine the working pressure of the trunnion cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, trunnion cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

trunnion cylinder is the most important part of construction machinery, the traditional processing method is: broaching trunnion cylinder block - fine boring trunnion cylinder block - grinding trunnion cylinder block. The rolling method is: broaching trunnion cylinder block - fine boring trunnion cylinder block - rolling trunnion cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the trunnion cylinder block is about 1-2 days, rolling 1 meter of the trunnion cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the trunnion cylinder increases by 25%. If the trunnion cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality trunnion cylinders, you must take the rolling production process. After the trunnion cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Disassembly trunnion cylinder: When disassembly trunnion cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the trunnion cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the trunnion cylinder.

The trunnion cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Answers to some questions about trunnion cylinder:

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
