Hydraulic oil delivery hose is an important equipment used for carrying and transmitting hydraulic oil. With the development of the construction machinery industry and the growth of demand, hydraulic oil delivery hoses play a crucial role in the field of construction machinery. Firstly, the hydraulic oil delivery hose has excellent pressure resistance performance. It has been carefully designed and specially processed to withstand the delivery pressure of high-pressure hydraulic oil. This enables it to stably and efficiently transmit hydraulic oil in various construction machinery equipment, ensuring the normal operation of the equipment. Secondly, the hydraulic oil delivery hose has excellent wear resistance. During the use of construction machinery, hydraulic oil delivery hoses are often exposed to harsh working environments, such as outdoor construction sites and potholes on roads. Therefore, hoses need to have excellent wear resistance, be able to withstand wear caused by various particles and friction, and extend their service life. In addition, hydraulic oil delivery hoses also have excellent corrosion resistance. The hydraulic oil commonly used in the construction machinery industry contains corrosive substances such as acids and alkalis, which poses high requirements for the material of hoses. The hydraulic oil delivery hose adopts corrosion-resistant special materials, which can effectively resist the erosion of these corrosive substances and ensure that the hose is not corroded and damaged in long-term use. Finally, the connection methods of hydraulic oil delivery hoses are diverse and flexible, suitable for different types of construction machinery equipment. Whether it is a loader, excavator, or bulldozer, hydraulic oil delivery hoses with different specifications and connection methods can be selected according to specific needs, achieving quick connection between the equipment and the hydraulic system. In summary, hydraulic oil delivery hoses, as indispensable key equipment in the field of construction machinery, have excellent performance such as pressure resistance, wear resistance, and corrosion resistance, providing reliable guarantees for the normal operation of construction machinery equipment. In future development, we look forward to continuous innovation and progress in hydraulic oil delivery hoses, making greater contributions to the development of the construction machinery industry.
