For the same hydraulic cylinder on the Internet, some manufacturers quote more than 1200, some more than 1600, some about 1800, and even some about 3000. This situation makes the purchasing manufacturers feel puzzled and very difficult. Most manufacturers have limited procurement funds, city in Guangxi Hydraulic station Therefore, if you want to achieve the predetermined purchase goal, you need to choose the hydraulic cylinder with high cost performance ratio, good quality and low price. However, the price gap of hydraulic cylinders in the market is staggering, city in Guangxi Hydraulic station manufactor If you choose cheap oil cylinder rashly, the quality cannot be guaranteed, which will lead to endless troubles.

There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic cylinder city in Guangxi Hydraulic station Top up with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, clean the hydraulic cylinder, and then add new hydraulic oil, city in Guangxi Hydraulic station manufactor Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.

The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, city in Guangxi Hydraulic station The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, city in Guangxi Hydraulic station manufactor The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.

If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. city in Guangxi Hydraulic station Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. city in Guangxi Hydraulic station manufactor The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
