Everyone knows that the high-pressure oil tubing is a consumable, but when you use it incorrectly, the consumption rate of the high-pressure tubing will be greater. As a professional manufacturer of high-pressure tubing, the following summarizes several common misuses of high-pressure tubing:
1. Subject to frequent and severe pressure shocks. Bursting of high-pressure hoses is generally not caused by excessive static pressure, but is related to the severity and number of pressure shocks. During the operation of construction machinery, the sudden increase or decrease of oil pressure will repeatedly occur in the oil pipe, which will cause frequent pressure shocks to the oil pipe, which will cause the oil seals in all parts to become more damaged, blistering and cracking of the hose, and loose and leaking joints Leak phenomenon. Therefore, during operation, the valve rod must not be pulled too hard, it must be gentle.
2. The operating temperature of the oil is too high. During the operation of construction machinery, the hydraulic system heats up the oil due to power loss, and the influence of external temperature (especially in summer), can cause the oil temperature to rise sharply. The higher the temperature of the oil, the easier the rubber will age, the elasticity will be worse, the strength and sealing performance will decrease, and the hose 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 promptly identified and eliminated; summer operations, especially continuous operations, should take necessary cooling measures.
3. The selection and installation of the oil hose is unreasonable. When replacing the high-pressure hose, the length of the hose, the number of steel wires, the shape and size of the joint must be reasonable, and the degree of bending of the hose should be minimized; when tightening the joint nut, do not distort the hose, excessive bending and Distortion will greatly reduce the service life of the hose; protection measures should be taken on some parts that are prone to friction to prevent the hose from bursting due to wear.
I hope everyone pays attention to the above points in the use of high-pressure oil pipes to avoid premature damage to the oil pipes due to improper use.
