ordinary Sandblasting hose Divided into high-pressure rubber Sandblasting pipe It is almost the same as the low-pressure rubber sand blasting pipe from the surface. However, the actual function and air forming process are very different, so how can we determine Sandblasting hose What about the quality?

Sandblasting hose It is generally composed of four parts: outer rubber layer, steel wire reinforcement layer, middle rubber layer and inner rubber layer. The inner rubber layer is directly contacted by hydraulic oil and is usually made of synthetic rubber. The bearing capacity of high-pressure rubber sand blasting pipe depends on the reinforcing layer, which is the skeleton of rubber sand blasting pipe and is usually braided or coiled with steel wire. Most of the medium and high pressure wire mesh is used as a frame, and most of the high pressure and ultra-high pressure wire coils are used as a frame. The external rubber layer is usually made of rubber with good wear resistance and corrosion resistance to ensure that the reinforcing layer is not affected by mechanical hazards, chemical corrosion and wet rust. Low pressure rubber sand blasting pipe is generally used for low-pressure oil return pipe with braided cotton and hemp instead of braided steel wire.

Users who have some knowledge of the use of hydraulic soft rubber sand blasting pipes may know that they may burst in our actual operation, which causes serious harm to production and operation, and is difficult to maintain, often leaving people helpless. Therefore, the right choice is to reduce this possibility to a lower level and eliminate the danger in the cradle. Specifically, the following precautions are usually taken:

1. If the tiller with limited depth wheels is suspended, it is necessary to operate in the "floating" position instead of the "neutral" position.

2. If the distributor cannot return on its own initiative, it must be repaired without delay. If it is a distributor without active return, the rudder stock shall return to the "neutral" position immediately after "raising" or "lowering" to the final position.

3. If hydraulic soft rubber tubing is used to transport farm tools, the speed should be reasonably selected according to the flatness of the road surface to prevent the machine from failure and damage due to excessive piston load.

4. The opening pressure of the distributor safety valve should be adjusted correctly according to the operating conditions of the machine.

5. According to the actual situation of the soil, the degree of the soil pressure drop should be controlled, rather than the unlimited "pressure drop", otherwise it is easy to cause damage to the machine.

The above content is about the inspection method of the quality of sandblasting hose. I hope it will be helpful to everyone.
