oil pressure gauge tubing
Oil pressure gauge tubing: The pipelines connecting hydraulic system components are also known as "oil tubing". Its function is to connect various hydraulic components in the hydraulic system to ensure the circulation and energy transmission of the hydraulic system. The requirements for pipelines are: low energy loss during the oil transportation process, sufficient strength, and easy assembly and use. When selecting pipelines, the selection should be based on the pressure, flow rate, and working medium of the system. When selecting a joint, it is necessary to match the additional working pressure with the pressure eliminated by oneself in order to select a suitable joint and avoid affecting the normal use of the machine during the working process. If the high-pressure hose connector meets the mechanical strength, the area and shape of the overcurrent will be the same as the hose, so a speed connector can be selected to avoid some impact.The function of hydraulic oil tubing is to connect hydraulic components and transport hydraulic oil. In hydraulic systems, commonly used hydraulic oil tubing include steel tubing, copper tubing, plastic tubing, nylon tubing, and rubber hoses, which can be selected according to specific purposes. How to distinguish between high-pressure and low-pressure oil tubing in hydraulic systems? What are the differences in the functions of high-pressure and low-pressure oil tubing? Some require high-pressure hydraulic oil tubing, while others require low-pressure hydraulic oil tubing. So what are the differences between them? What are the functions of high-pressure and low-pressure oil tubing?
The difference between high-pressure oil tubing and low-pressure oil tubing is that there is a steel wire woven or wrapped in the middle of the high-pressure oil pipe to form a reinforcing layer. The low-pressure pipe body is relatively soft, and there are clips or cords in the middle of the pipe body. In theory, the distinction between low-pressure and high-pressure hoses is based on the pressure level of the hose design. But currently, the same product has different standards in different industries. The pressure of the high-pressure pipe should not be less than 8MPa. Those below 8MPa are considered low-pressure hoses.
The functions of high-pressure oil tubing and low-pressure oil tubing are: high-pressure oil tubing are used to withstand high pressure fluid media and output power; The low-pressure oil pipe is obviously not used to transport the return oil end. Generally speaking, high-pressure oil tubing are commonly used as hydraulic oil tubing; The common low-pressure oil pipe is the hydraulic return pipe.
In addition, there are many differences in the structure between low pressure oil tubing and high pressure oil tubing. High pressure oil tubing generally purchase steel wire reinforcement layers, while low pressure oil tubing often use cotton thread and textile rope as the intermediate layer of the hose due to their low pressure resistance.
