Most of the oil tubing damage during normal work is caused by improper use. The incorrect operation can greatly shorten the life of the tubing. The following describes the precautions for the use of tubing:
(1) The valve stem should be pulled gently. Due to frequent and severe pressure shocks, the tubing will burst. This situation is related to the severity and frequency of pressure shocks. During the operation of the construction machinery, the sudden increase or decrease of the oil pressure will occur repeatedly in the oil pipe, which will cause frequent pressure shock to the oil pipe, resulting in increased oil seal damage in various parts, foaming and cracking of the oil pipe, and loosening of the pipe joint. Leakage phenomenon. Therefore, the valve stem should not be pulled too hard during operation, so it must be gentle.
(2) Avoid excessive use of oil. When the construction machinery is working, the hydraulic system generates heat due to power loss, and the influence of outside air temperature (especially in summer) can cause the oil temperature to rise sharply. The higher the temperature of the oil is used, the more likely the rubber will age, the elasticity will deteriorate, the strength and sealing performance will decrease, and the tubing will burst quickly. Therefore, in the operation, when the temperature rise of the hydraulic system is too high or too fast, the cause should be identified and eliminated in time; in summer work, especially in continuous operation, the necessary cooling measures should be taken.
(3)Avoid improper operation of the oil tubing. When replacing the oil pipe, the length of the selected oil pipe, the number of steel layers, the shape and size of the joint should be reasonable, and the degree of bending of the oil pipe should be minimized; when tightening the joint nut, do not make the oil pipe twist, excessive bending and twisting. It will greatly reduce the service life of the tubing; protective measures should be taken for some parts that are prone to friction to prevent the tubing from bursting due to wear.learn more about assembling rubber hose.
