The layout of high-pressure hoses

High-pressure hoses are widely used in the coal industr


High-pressure hoses are widely used in the coal industry and petroleum industry to transport petroleum, mineral oil, lubricating oil, emulsion, hydraulic oil, oil-water emulsion, etc. Today, let’s take a look at what aspects should be paid attention to when using high-pressure hoses:

(1) The layout of high-pressure hoses should minimize heat sources and prevent the main performance of engine exhaust pipes. If necessary, equipment such as waterproof casing or protective screen can be used to prevent the high-pressure hose from becoming mildewed when exposed to heat.

(2) The high-pressure hose must be crossed or where it may rub against the surface of the machine during operation. Use a high-pressure hose clip or spring protector to prevent the surface of the hose from being damaged.

(3) When the high-pressure hose must be bent, the bent half diameter should not be too small, and should be more than 9 times the diameter. There must be a parallel line segment that exceeds 2 times the diameter of the water pipe at the junction of the rubber hose and the connector.

(4) When installing the high-pressure hose, avoid being in a tight state. Even if there is no relative speed on both sides of the high-pressure hose, keep the high-pressure hose loose. The tight high-pressure hose can expand under pressure. Reduced compressive strength.

(5) Do not twist the high-pressure hose during installation. Slight twisting of the high-pressure hose will reduce its compressive strength and loosen the connector. When assembling the line, the connector should be tightened on the high-pressure hose instead of the high-pressure hose tightened on the connector. .

(6) If the high-pressure hose is equipped on the core components, regular maintenance or replacement is recommended.
