The hydraulic cylinder is composed of a main engine and a control mechanism. The main parts of the cylinder include the body, the master cylinder, the ejector cylinder and the liquid filling device. The power mechanism is composed of oil tank, high pressure pump, low pressure control system, motor, pressure valve and direction valve. Under the control of the electric device, the power mechanism realizes the energy conversion, adjustment and transmission through the pump, the cylinder and the hydraulic valve to complete the cycle of the process action. Its working mode is reciprocating motion. The machinery manufacturing industry produces cylinders and fasteners, while the chemical industry generally produces seals. The cylinder manufacturer should have a clear understanding of the sealing technology, and the seal manufacturer should also understand how the cylinder works.
The piston part of the hydraulic cylinder will extend out of the cylinder in the working state, and will be eroded by oxide and acid gas, which requires us to apply an appropriate amount of grease on the above for protection, to prevent the piston as a bearing part from being eroded and possibly broken during the working process. Second, open the box and change the oil. Due to long-term use, foreign bodies will inevitably enter the cylinder, resulting in friction during use. In addition, the hydraulic oil has a long service life, and not changing the oil for a long time will damage or corrode the cylinder. Therefore, the working speed of the cylinder should be properly controlled, not exceeding 2m/s, which can increase the service life of the cylinder. In addition, in order to protect the mechanism and safety, the installation of a buffer device in the cylinder helps to protect the hydraulic cylinder.
Several manifestations of foreign bodies entering hydraulic cylinders
1. Pay attention to cleaning the hydraulic cylinder. When the pipe is cleaned again after installation, it should not pass through the cylinder again.
Instead, the pipe should be installed in front of the cylinder port. Otherwise, foreign matter in the pipe will go directly into the cylinder.
During the cleaning process, it is necessary to remove foreign matter from the pipe.
2. For the chips generated in the process of pipeline processing, after the pipeline is cut to a certain length and processed,
the burrs should not be left behind when removing the burrs at both ends, or the steel pipe should not be placed around the operation of the welded pipeline,
because it is easy to cause welding foreign matter to mix, so if the pipeline needs to be placed around, the pipe mouth should be directly sealed.
Stack the pipes on a dust-free work table.
3. A simple sealing material is brought into the hydraulic cylinder when sealing. In the installation and inspection, we will use different winding methods,
such as straight winding and sealing belt, so that the sealing belt will be cut off and used, and then directly into the cylinder.
Moreover, the linear seal will affect the winding connection, and the hydraulic cylinder check valve is not flexible when it is serious.
The above is about the impact of long-term oil change on the hydraulic cylinder analysis, if you have other hydraulic cylinder related questions, please feel free to consult us.
