Malaysia hydraulic cylinder,hydraulic engineering cylinder manufacturer,hydraulic engineering cylinder(Malaysia hydraulic engineering cylinder,produced by Hebei Hengyu company)
hydraulic engineering cylinder are widely used in Malaysia,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed hydraulic engineering cylinder for customers from Malaysia.
The piston seal of the hydraulic engineering cylinder is the main element to prevent leakage in the hydraulic engineering cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
When the hydraulic engineering cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
hydraulic engineering cylinder piston rod material introduction: In general, we use 45 steel to produce hydraulic engineering cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.
Improve the service life of the hydraulic engineering cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the hydraulic engineering cylinder (such as the hydraulic engineering cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the hydraulic engineering cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the hydraulic engineering cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single hydraulic engineering cylinder exhaust.
What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
