The classification of hydraulic hose

With the continuous development of science and technology and the application of excavators more and more widely

With the continuous development of science and technology and the application of excavators more and more widely, the hydraulic system has become an important part of the excavator. In the hydraulic system of the excavator, the hydraulic hose is an inconspicuous but vital part, whose function is to transmit hydraulic oil, control oil pressure and transfer power. In the heavy-duty working environment of excavators, hydraulic hoses need to withstand various harsh conditions such as high pressure, high temperature, cold, dust, humidity and chemical corrosion. Therefore, the special hydraulic hose for long-life excavators must meet various performance requirements such as high strength, wear resistance, corrosion resistance, high temperature resistance and low temperature resistance, so as to ensure the normal operation and long-term stable operation of the excavator.

First, the classification of hydraulic hose

Hydraulic hoses can generally be divided into two categories: low pressure hoses and high pressure hoses.

1. Low pressure hose
   Low-pressure hydraulic hoses are mainly used in low-pressure hydraulic systems, and the general working pressure is below 6Mpa. The structure of the low-pressure hose generally adopts a three-layer structure of inner rubber layer, reinforcing layer and outer rubber layer. The inner rubber layer is generally made of synthetic rubber, and the outer rubber layer is generally made of wear-resistant rubber or synthetic rubber.
2. High pressure hose
   High-pressure hydraulic hoses are mainly used in high-pressure hydraulic systems, and the general working pressure is above 16Mpa. The structure of the high-pressure hose generally adopts multi-layer steel wire braiding or spiral steel wire reinforcement layer. The more the number of steel wire layers, the stronger the pressure bearing capacity. The inner rubber layer of the high-pressure hose is generally made of oil-resistant synthetic rubber, and the outer rubber layer is generally made of wear-resistant rubber or synthetic rubber.

Second, the characteristics of hydraulic hoses for long-life excavators

1. High strength
   The hydraulic hose for long-life excavators is made of high-strength steel wire braid and outer rubber material, which can withstand the impact of high pressure and sudden pressure, and prevent the hose from bursting and oil leakage.
2. Wear resistance
   The inner material of the long-life hydraulic hose for excavators is made of wear-resistant and friction-resistant synthetic rubber, which can resist wear and friction when the excavator is working, and prolong the service life of the hose.
3. Corrosion resistance
   The material of long-life excavator special hydraulic hose has good corrosion resistance, and can be used in various chemically corrosive liquid media, such as acid, alkali, oil, salt water, etc.
4. High temperature and low temperature resistance
   The material of long-life excavator special hydraulic hose can work normally in high temperature and low temperature environment, and can withstand the temperature range of -40°C to +120°C.
5. High reliability
   The production of hydraulic hoses for long-life excavators adopts a professional production line, and the products have undergone many strict tests and inspections to ensure the quality and reliability of the products.

Third, the application of hydraulic hoses for long-life excavators

Long-life hydraulic hoses for excavators are mainly used in hydraulic systems of various construction machinery such as excavators, loaders, bulldozers, road rollers, forklifts, cranes, and concrete pump trucks. In the hydraulic system of the excavator, the special hydraulic hose for the long-life excavator is widely used, and its reliability and performance are superior, which can ensure the normal operation and long-term stable operation of the excavator in the heavy working environment.

Fourth, how to choose a hydraulic hose for long-life excavators

1. Choose products produced by regular manufacturers
   When choosing special hydraulic hoses for long-life excavators, you should choose products produced by regular manufacturers. Products produced by regular manufacturers generally use high-quality materials, high-tech production technology, stable and reliable product quality and performance.
2. Pay attention to the size and working pressure of the hose
   When selecting hydraulic hoses for long-life excavators, attention should be paid to the size and working pressure of the hoses. The size of the hose should match the requirements of the hydraulic system to ensure that the hose works effectively. The working pressure should match the working pressure of the hydraulic system to ensure that the hose can withstand the working pressure of the hydraulic system.
3. Pay attention to the use environment of the hose
   When selecting hydraulic hoses for long-life excavators, attention should be paid to the use environment of the hoses. Different environments have different requirements on the performance of hoses such as wear resistance, corrosion resistance, high temperature resistance and low temperature resistance, so the appropriate hose should be selected according to the actual situation.

In short, the hydraulic hose for long-life excavators is an important part of the hydraulic system of the excavator, which needs to meet various performance requirements such as high strength, wear resistance, corrosion resistance, high temperature resistance and low temperature resistance. Only by selecting high-quality long-life hydraulic hoses for excavators can the normal work and long-term stable operation of the excavator be guaranteed.
