Manufacturers Talk About How Long The Service Life Of Pu Steel Wire Retractable Hose

How long is the service life of pu steel wire telescopic hose? Please listen to pu steel wire telescopic hose manufacturers for your analysis: pu steel wire telescopic hose is an important part of the ultrahigh-pressure cleaner, is an important original connection between the nozzle and the ultrahigh-pressure pump. Ultrahigh-pressure cleaner in the use of the process, the impact of pu steel wire telescopic hose service life of many factors. In addition to the level of craftsmanship in the manufacturing process of the hose, the quality and performance of the inner layer and joints, pu steel wire telescopic hose of the correct choice and use of many factors such as the service life of the pu steel wire telescopic hose has a great impact. Here are three main factors that affect the service life of pu steel wire retractable hose.

First, the pressure match

And in the use and selection of pu steel wire retractable hose, according to the working pressure of the ultra-high-pressure cleaner, the correct choice of the appropriate pressure level of the hose. When the actual pressure exceeds 1.25 times the specified pressure, the service life of the hose will be reduced by 50%.

In addition, the pressure fluctuation of the ultra-high-pressure cleaner during the working process, the fluctuation of fluid pressure in the pipeline caused by the instantaneous opening and closing of the high-pressure spray gun and control valve has a great impact on the service life of the pu steel wire telescopic hose. So it is recommended to choose pu steel wire telescopic hose according to the working pressure of 1.5 times. For example, the working pressure of 1200bar ultrahigh-pressure cleaner, you should choose the working pressure of 1800-2000bar pu steel wire telescopic hose. This can greatly extend the service life of pu steel wire telescopic hose.

Second, path matching

When equipped with pu steel wire telescopic hose, should be selected according to the requirements of the host of ultrahigh-pressure cleaner, because the pressure and flow of ultrahigh-pressure cleaner has very strict regulations or restrictions, changes in the inner diameter of the pipeline will affect the front end of the high-pressure water jets work impact and the balance of the system. Experiments have proved that with 4mm pu steel wire telescopic hose instead of 5mm pu steel wire telescopic hose service life reduced to one-third of the original.

Three. pu steel wire telescopic hose use, storage and custody of specific requirements

(1) ultrahigh-pressure cleaner is in working condition, the hose shall not be twisted, try to avoid bending. If you need to bend, make sure that the bending radius is not too small, generally not less than 15 times the outer diameter of the tube, otherwise it will make the reinforcement layer of the outer layer of steel wire is stretched, the inner layer of steel wire is compressed, which reduces the overall compressive strength of pu steel wire telescopic hose, and ultimately affects the service life of the hose.

(2) ultrahigh-pressure cleaner in the working state, pu steel wire telescopic hose can not be crushed by heavy objects, sharp objects touching can not be bent, should protect the outer layer from excessive wear and tear; hanging high-pressure tube should be fixed firmly within a short distance.

(3) In the specific cleaning operation, try to avoid frequent switching hand-held high-pressure spray gun, in order to reduce the pressure pulse on the hose, to extend the service life of the hose.

(4)In order to prevent accidents and injuries when the joints are dislodged or damaged, the pu steel wire telescopic hose should be connected at the joints with a steel wire braided protective sleeve connecting the two ends.

(5) When installing and dismantling the pu steel wire expansion hose fitting, forced dismantling and twisting of the fitting is not allowed. The threads of the connection threads should be protected. Meanwhile, lubricant is required to be applied to the outer surface of the threads during installation. After disassembly, the connection threads shall be protected by a protective sleeve.

(6) When pu steel wire telescopic hose is not used for a long time, the internal water should be drained, and the hose should be rolled according to the specified size and then put flat. Special attention should be paid to the pu steel wire retractable hose connector bending. The joints should be coated with anti-rust oil to avoid contact with high temperature, high pressure and strong corrosive media.
