The use environment of low pressure hose

The use environment of low pressure hose

The low-pressure hose is specially assembled, and the hose with a total length of 2m (including joints at both ends) weighs only 500 grams. It greatly reduces the work intensity of the operator, and at the same time has strong softness, free bending, and no dead folds to hinder ventilation. The low pressure hose is resistant to corrosion, high temperature and low temperature (-196℃~+420℃), light weight, small size and good flexibility. Low-pressure hoses are widely used in chemical, mechanical, electronic, electrical, military, aerospace, pipeline, petroleum, textile machinery, electrical insulation, environmental protection and other economic fields. Because the low pressure hose adopts special high-grade PTFE hose, high temperature resistant braided mesh and Japanese advanced technology stainless steel double buckle spiral hose, it is suitable for special environments of high temperature, corrosion and high pressure. Under the pressure of 3kg/cm2, the low-pressure hose can withstand 250°C high temperature steam inside the hose, and the skin temperature does not exceed 60°C to ensure safe operation. The low pressure hose can be used normally under the steam pressure of 10kg/cm2.

The quality problem of high-pressure hose is related to improper use

The high-pressure hose is a kind of liquid transmission pipeline commonly used in agricultural machinery. During our use, under the premise of quality assurance, if the high-pressure hose is used improperly, the service life of the high-pressure hose will be greatly shortened. In actual work, most of the damage to the high-pressure hose is caused by improper use.

Development and application of pressure test device for high pressure hose

Development and application of pressure test device for high pressure hose

High pressure rubber hose is an important tool used by our company in the cementing construction process. In the process of use, because there is no inspection method, there is no inspection standard for whether the high-pressure rubber hose is still in the safe period; whether the pipeline can still meet the construction requirements during use cannot be verified; before the pipeline is purchased and put into storage, the pipeline inventory is more than one year. , is still usable; the certificate provided by the manufacturer has no measurement standard. Based on the above reasons, we choose to make a high-pressure rubber hose inspection device to fill the gap of no inspection means, and at the same time meet the safety inspection of high-pressure rubber hoses in the process of procurement, inventory and use.

The working principle of hydraulic high pressure hose crimping machine

The working principle of hydraulic high pressure hose crimping machine

Hydraulic hose crimping machine is the main equipment for manufacturing hydraulic hose joints. By crimping the joint jacket, the joint jacket, the hose and the joint inner core are integrated to form a hydraulic hose joint assembly. At present, the pressure withholding force of domestic design and manufacture or press modification is determined by experience, test, analogy and other methods. Therefore, the equipment capacity is too large, the volume and weight are too large and other defects and deficiencies. During the crimping process, there are disadvantages such as unstable crimping quality, low tube shrinking efficiency, and easy fatigue of operators. The improved crimping machine not only saves manpower, but also improves crimping quality and tube shrinking efficiency.
