If the spiral swing oil cylinder fails, it will affect the work efficiency, so in order to better use the spiral swing oil cylinder, the user needs to check the oil cylinder at any time, if any problems are found, repair in time to avoid more serious failures. It is recommended that you check and repair the following areas:
The spiral swing oil cylinder is an important force transmission component in the hydraulic system. Its quality directly affects the use and performance of the machine. Hydraulic cylinder leakage is one of the main reasons for the failure of hydraulic cylinders. Hydraulic cylinder leakage includes external leakage and internal leakage. Leakage refers to the external leakage of the cylinder barrel, cylinder head, and cylinder bottom. The spiral swing cylinder can be directly viewed from the outside. It refers to the leakage of pressure oil from the high pressure chamber of the hydraulic cylinder to the low pressure chamber. It occurs on the inner wall of the piston and the cylinder The connection between the inner bore of the piston and the piston.
The piston of the spiral swing cylinder is the main component to prevent internal leakage of hydraulic oil. During the inspection process, the machine can be operated in accordance with normal operating specifications, and then the directional valve is operated to extend the piston to the extreme position. At this time, the hydraulic support cylinder is in a lifting state. Disassemble the oil port of the oil return line of the hydraulic cylinder and observe whether the hydraulic oil is leaking. If leakage of hydraulic oil is found, check the wear of the seals and check whether the seal between the piston and the piston rod is intact. If the inspection results show that the seal and the guide support ring have different degrees of damage, they should be made and replaced with materials of the same specification according to the original seal or guide support ring structure, thereby reducing the oil film on the seal and the sealing surface. Thickness to avoid the recurrence of the leakage failure of the spiral swing cylinder.
Due to the unsatisfactory sealing effect between the inner wall of the cylinder of the spiral swing cylinder and the piston, leakage failure may also occur. During the inspection process, if there is no strain in the cylinder, it can indicate that the piston and the inner wall of the cylinder have relatively severe wear, so the piston needs to be replaced.
The above is the introduction of the inspection and maintenance of the spiral swing cylinder. If you want to know more related issues, please continue to pay attention to us.
