The automobile brake pipe hard pipe has an inner shielding layer, and the automobile brake pipe hard pipe is suitable for multiple functions such as shearing and expansion at the rescue site. Regular inspection of automobile joint sealing and mechanical protection is the guarantee to ensure the safe and reliable operation of joints. During installation, moisture and moisture should be avoided in the joints. In addition, joint protection grooves or cement protective boxes should be built at the joint position. Generally, the cable body has an inner shielding layer. When making the connector, we must restore the inner shielding layer of the connector of the conductor part of the crimping tube. They are connected to each other to ensure the continuity of the internal semiconductor during use, so that the field strength at the joint is evenly distributed. Speaking of internal semiconductors, there must be external semiconductors. The external semiconductor shielding is a semi-conductive material that acts as a uniform electric field on the outside of the cable and joint insulation. Like the internal semiconductor shielding, it plays a very important role in both the cable and the joint, but the external semiconductor port It must be neat and uniform, and smooth transition with insulation. The semiconductor tape is wound at the joint to connect with the semiconductor shielding tower outside the cable body.

Choose the inner diameter of the hose according to the flow rate. If the pipe diameter is too small, it will increase the flow rate of the medium in the pipe, cause the system to heat up, reduce the power, and cause excessive pressure drop, which will affect the performance of the entire system. If the pipe diameter is too large, it will increase the cost. The inner diameter of the hose should be appropriate. When the hose is fixed with a pipe clamp or the hose passes through the steel plate or the like, pay attention to the outer diameter of the hose. According to the pressure of the high-pressure hose system, select the number of steel wire layers of the hose, the pressure is high, and the number of steel wires is more. Each type of hose has a maximum operating pressure, and the explosion pressure of the hose is 4 times the maximum operating pressure. The higher the pressure resistance of the hose, the higher the price, so according to the actual system pressure, the maximum operating pressure of the selected hose should be higher than the actual operating pressure. If the impact pressure of the system is frequent, use a hose that is particularly resistant to pulses.
