The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Yinchuan Hydraulic station Price It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Yinchuan Hydraulic station Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.

For the selection of hydraulic cylinder, the hydraulic cylinder will be selected according to the inner diameter, stroke, operating pressure and installation type during the selection of hydraulic cylinder. In fact, in addition to these, we should pay attention to the following points. First, when the hydraulic cylinder is loaded and then the actuating speed reaches a certain standard, Yinchuan Hydraulic station Hydraulic cylinder with buffer device must be used. Or when the speed reaches a higher speed, a deceleration valve must be installed outside the hydraulic cylinder; Secondly, carefully select hydraulic oil and oil seal. Oil seals of different materials are selected for different hydraulic oils, Yinchuan Hydraulic station Price To ensure the service life of the hydraulic cylinder.

Select the cylinder type correctly according to the working requirements and conditions. It is required that there is no impact phenomenon and impact noise when the cylinder reaches the end of the stroke; Cushion cylinder shall be selected; Light weight is required; It is required to select light cylinder; Yinchuan Hydraulic station Narrow installation space and short stroke are required; It is required to select thin cylinder; It is required to have transverse load, and the cylinder with guide rod can be selected; High braking accuracy is required, and locking cylinder can be selected; It is not allowed to rotate the piston rod, and the cylinder with rod non rotation function can be selected; Yinchuan Hydraulic station Price In corrosive environment, corrosion-resistant steel cylinders shall be selected.

1. There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Yinchuan Hydraulic station Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Yinchuan Hydraulic station Price Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.

Items to be checked when the speed of hydraulic cylinder slows down. 1. Where and what type of oil cylinder has been used for several years, Yinchuan Hydraulic station What is the working pressure. You don't have any of these. How can I troubleshoot them for you. Check the lower seal if there is internal leakage. 2. It is likely that the internal working pressure of the oil cylinder has decreased. 3. Check whether the system is blocked, Yinchuan Hydraulic station Price In addition, check whether the oil cylinder seal ring is damaged, and then check whether the piston rod is damaged. Basically, these aspects can identify the problem.

Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Yinchuan Hydraulic station The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Yinchuan Hydraulic station Price In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.
