(Algeria hydraulic hollow cylinder,produced by Hengyu Group）
hydraulic hollow cylinder are widely used in Algeria，because of excellent temperature resistance，no need for deceleration device，long service life.So our company has designed hydraulic hollow cylinder for customers from Algeria.
The hydraulic hollow cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the hydraulic 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 hydraulic hollow cylinder wall due to the stiffness and the weight of the parts, causing scars.
When using the hydraulic hollow cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the hydraulic hollow cylinder block. If the hydraulic hollow cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the hydraulic hollow cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the hydraulic hollow cylinder, so that the working efficiency of the hydraulic hollow cylinder is reduced.
We can not just consider the price and ignore the quality when we purchase the hydraulic hollow cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the hydraulic hollow cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the hydraulic hollow cylinder is not required.
After chrome plating of the piston rod of the hydraulic hollow cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
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).
