Slovenia hydraulic cylinder,non-standard special type cylinder manufacturer,non-standard special type cylinder(Slovenia non-standard special type cylinder,produced by Hebei Hengyu company)
non-standard special type cylinder are widely used in Slovenia,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed non-standard special type cylinder for customers from Slovenia.
In the case of serious wear on the inner surface of the non-standard special type cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the non-standard special type cylinder manufacturing process for replacement. The non-standard special type cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
If the seal of the non-standard special type 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 non-standard special type cylinder, and the phenomenon of "pulling the non-standard special type 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.
non-standard special type cylinder and hydraulic station selection: Select the type and structure of the non-standard special type cylinder according to the operation requirements of the main engine. According to the external load force borne by the non-standard special type cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the non-standard special type cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the non-standard special type cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the non-standard special type cylinder, the diameter of the piston and the piston rod.
The viscosity of the working oil used in the non-standard special type cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.
Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
