wire braid hose assembly manufacturers suppliers in bangalore

wire braid hose assembly, also called the hose assembly or the hose connector, is the assembly structure of the two ends and the metal connection joints of the steel wire braided or wound reinforcing hose after being crimped and assembled. The
The steel wire reinforced layer of rubber hose is generally divided into steel wire braiding and steel wire winding. The number of reinforced layers is generally from 1 layer to 6 layers. The inner rubber layer contains the fluid medium, the reinforcing layer is the skeleton, and the pressure is ensured. The outer rubber layer Protection enhancement layer
Temperature range: -40°C~+100°C
Working pressure: up to 60MPa
Medium: Hydraulic power transmission or delivery of high pressure media such as water, gas, and oil to ensure liquid circulation and transfer of liquid energy.
Precautions
First, the inner diameter of the tube: the inner diameter of the hose.
Second, the use of the hose and design should pay attention to the following matters:
1. The bending radius of the hose should not be too small. Generally, it should not be less than the value specified in the “Technical Characteristics of Hydraulic Hose Assembly”. The connection between the hose assembly and the pipe joint should have a straight section. The length of this section should not be less than twice the outside diameter of the pipe.
2. The length of the hose assembly should take into account that after the hose is pressurized with pressure oil, the length of the hose will shrink. Generally, the shrinkage is 3 to 4% of the length of the hose. Therefore, when the hose assembly is installed, it is not allowed to be in tension.
3, the hose assembly should be installed to ensure that no distortion occurs. The joint axis of the hose should be placed in the plane of motion as much as possible to avoid damage to the hose when the two ends move.
4. The hose should avoid contact and friction with the sharp corners of the machine to avoid damage to the pipe.
Third, security measures: In order to ensure the safe and reliable use of the hose assembly, the following special attention.
1. Pressure: The specified working pressure of the hose can not be less than the maximum system pressure under normal circumstances, only allowed to increase by 20% in the case of infrequent use, and 40% for frequent use and frequent bending and twisting. If the impact pressure of the system is higher than the specified working pressure of the hose, not only the service life of the hydraulic hose is reduced, but also personal equipment accidents may occur.
2. Temperature: The fluid temperature and the ambient temperature, whether it is stable or instantaneous, shall not exceed the temperature limit of the hose, the temperature is lower or higher than the recommended temperature of the hose, can reduce the performance of the hose, causing the hose Damage caused leakage.
3, fluid compatibility: The fluid in the hose, should comply with the provisions in the “use” in the product sample, beyond the specified use can not guarantee the service life and safety of the pipe.
4. Appropriate end connection: Since nut connection is convenient and cost is low, it is widely used. However, in the case of large vibration, nut looseness should be fully taken into account and the connection to blue should be adopted.
