(Paraguay trailer hydraulic cylinder,produced by Hengyu Group）
trailer hydraulic cylinder are widely used in Paraguay，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed trailer hydraulic cylinder for customers from Paraguay.
The pressure of the sliding surface of the trailer hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the trailer hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
trailer hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the trailer hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
If the seal of the trailer hydraulic 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 trailer hydraulic cylinder, and the phenomenon of "pulling the trailer hydraulic 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.
The trailer hydraulic cylinder is mainly composed of body, piston, piston rod, trailer hydraulic cylinder head, trailer hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the trailer hydraulic cylinder into two chambers, and moves reciprocally in the trailer hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the trailer hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the trailer hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the trailer hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the trailer hydraulic cylinder bottom and the trailer hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the trailer hydraulic cylinder The working medium of the trailer hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; trailer hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the trailer hydraulic cylinder: The buffer structure of the trailer hydraulic cylinder is to prevent the piston from colliding with the trailer hydraulic cylinder head at the end of the stroke.
Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.
Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
