It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Qinghai Cylinder The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Qinghai Cylinder Price Flow rate and flow direction. For example: pressure control valve, flow control valve.
Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Qinghai Cylinder 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. Qinghai Cylinder 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.
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, Qinghai Cylinder 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, Qinghai Cylinder 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.
How to install and fix the hydraulic cylinder? There are two common ways to fix the hydraulic cylinder: the first is the square hydraulic cylinder fixed on the B plate, and the hydraulic cylinder needs to be positioned on the B plate. The second is a round hydraulic cylinder fixed on the ejector plate. It should be noted that the thimble plate locking screw needs to be added next to the hydraulic cylinder, and the force at this position is large, Qinghai Cylinder Prevent tension deformation. Another point is to inscribe words on the hydraulic cylinder, and write down the stroke of the hydraulic cylinder for easy verification. To correctly install the sealing device at each position of the hydraulic cylinder: Qinghai Cylinder Price When installing the O-ring seal, pay attention to its installation direction to avoid oil leakage due to installation. Its lip should face the oil chamber with pressure.
