Romania hydraulic cylinder,hollow cylinder manufacturer,hollow cylinder

(Romania hollow cylinder,produced by Hengyu Group）

hollow cylinder are widely used in Romania，because of no transmission clearance，clever hydraulic energy conversion，powerful torque.So our company has designed hollow cylinder for customers from Romania.

Introduction to hollow cylinder:

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

The hollow cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the hollow 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 hollow cylinder wall due to the stiffness and the weight of the parts, causing scars.

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

The hollow cylinder should be vented: when the hollow cylinder is installed or parked for a long time to work again, the air will penetrate into the hollow cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the hollow cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the hollow cylinder, the oil is best entered and discharged from the highest point of the hollow cylinder. hollow cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about hollow cylinder:

Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).
