Today, as science and technology shift towards productivity models, the global industrial production pattern is still undergoing significant changes.High-pressure steel wire braided hoseAs a common product in the field of machinery, it is widely used in equipment such as loaders, excavators, rollers, forklifts, hydraulic cranes, etc. In recent years, due to the increasing demand for oil, mining, agriculture, and industry, there has been a great demand for high-pressure steel wire braided rubber hose products that can adapt to the environment and meet industrial production needs.

High pressure steel wire braided rubber hoses are mainly used for transporting liquids with certain temperature and pressure in industries such as coal and petroleum. In order to understand the product performance of high-pressure steel wire braided rubber hoses, manufacturers and quality inspection units need to set up a certain pressure and temperature control environment, so that the test specimens can reach the actual working state for fatigue life testing to determine product performance. The testing method is as follows:

1. PTM series hose pulse testing machine

The PTM series hose pulse testing machine adopts an automatic servo control system, which can set the pulse pressure, pulse frequency, test times, and pulse waveform by itself. It has the function of automatic shutdown protection after the equipment specimen is damaged. The main components are imported parts, which are safe and reliable; Dynamically display test data on the interface, draw real-time pressure waveforms, generate test reports, and print them.

2. BTM series hose burst tester

The present invention can meet the high and low pressure requirements of 0.01~350Mpa rubber hose bursting pressure, and can perform pressure resistance, pressure resistance, and bursting tests on high-pressure manifolds, high-pressure bare pipes, and pipe joints. There are more than ten types of boost control methods that can meet the requirements of different pipe diameters, pressures, boost rates, and curves.

In addition to ensuring safe and reliable product quality, selecting appropriate hose products based on usage requirements is also an important factor in ensuring the safety and rationality of the entire system. When choosing high-pressure steel wire braided rubber hoses, the following points should be noted:

1. Select the number of steel wire layers for the rubber hose based on the system pressure. The higher the pressure, the more steel wire layers there will be. The working pressure of each hose is very high, and the burst pressure of the hose is four times that of the large working pressure. Therefore, based on the actual system pressure, the large working pressure of the selected hose can be slightly higher than the actual working pressure.

2. Choose the inner diameter of the hose based on the flow rate. If the diameter is too small, it will increase the flow rate of the medium inside the hose, raise the system temperature, reduce efficiency, generate excessive pressure drop, and affect the performance of the entire system. If the pipe diameter is too large, it will increase the cost, so the inner diameter of the hose should be appropriate. When fixing a hose or threading a hose through a gasket (such as a steel plate) with a pipe clamp, pay attention to the outer diameter of the hose.

When choosing a high-pressure steel wire braided rubber hose, attention should be paid to the bending radius. When calculating the bending radius, subtract the crimping length of the front joint. If the bending radius of the installed hose is too small, the pressure bearing capacity of the hose will be reduced and its service life will also be affected.
