How to effectively maintain the hydraulic hose
In emergencies, everyone will adopt some emergency methods for hose repair, but he did not expect that the performance of hydraulic hoses will be greatly reduced. Therefore, in practical applications, the situation of hose rupture should be avoided. maintenance.
Luohe Yibo Rubber Technology Co., Ltd. is a professional manufacturer of hydraulic hoses integrating R&D, production, sales and service. The main production: high-pressure / ultra-high-pressure wire wound / braided hose, mining high-pressure hose and assembly, assembly, joints. For most users, they lack this knowledge, and do not know how to use the method correctly and maintain the hose. Now I will tell you how to use the hose correctly to increase the service life of the hose and how to effectively use the hydraulic hose. The maintenance?
In actual work, most hoses are damaged due to improper use. Due to frequent and severe pressure shocks, the hose bursts. This situation is not generally caused by too much static pressure, but is related to the severity and number of pressure shocks. When the construction machinery is in operation, the sudden increase or decrease of the oil pressure in the oil pipe repeatedly causes frequent pressure shocks to the oil pipe, resulting in increased damage to the oil seals of the various parts, blistering and cracking of the hoses, and loosening of the pipe joints. Leakage phenomenon. Therefore, when operating, the valve stem must not be pulled too hard and must be gentle. The use temperature of the oil is too high to cause the hose to age and burst. When the construction machinery is in operation, the hydraulic system heats the oil due to power loss, and the influence of outside temperature (especially in the summer) can make the oil temperature rise sharply. The higher the oil temperature, the easier the rubber will age, the elasticity will be worse, and the strength and sealing performance will decrease, and the hose will burst soon. 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. In the summer operation, especially during continuous operation, the necessary cooling measures should be taken.
The use of hoses and improper installation caused the hose to break. When replacing the hose, the length of the selected hose, the number of layers of the steel wire, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized; when tightening the joint nut, the hose should not be distorted, excessively bent and twisted. The service life of the hose will be greatly reduced; protective measures shall be taken at some locations where friction is likely to occur to prevent the hose from bursting due to wear.
