Harbin Oil resistant hose It is composed of sand blasting hose, net sleeve and joint. The sand blasting hose is the main body of the rubber sand blasting pipe, playing a flexible role, and the net plays a role of strengthening and shielding; Joints play the role of connection. For different use requirements, they are connected in different ways: sandblasting hose, net sleeve and joint are connected by welding, which is called welding type; The connection in the form of mechanical clamping is called mechanical clamping. In addition, the combination of the above two methods is called hybrid clamping. Rubber sand blasting pipe products include oil suction hose, steam hose, sand blasting hose, acid and alkali suction hose, food hose, oxygen blowing hose and various special-shaped hoses. It is widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries. What is the pressure range of pressure resistant rubber sand blasting pipe: the pressure range of hose is generally Pn 0.6-32.0 MPa. The rubber sand blasting pipe up to 42.0 MPa is the main pressure bearing part of the hose installed in the pressure pipe, and it acts as the sheath of the sand blasting hose. Oil resistant hose Price One or more layers of stainless steel wire or steel strip can be selected for braiding according to the pressure in the pipeline and the place of use. It can also achieve the effect of reducing noise. This is why some rubber sand blasting pipes use rubber sand blasting pipes.

Harbin Oil resistant hose There are many specifications. Different installation positions require different specifications of cloth clamping sand blasting pipe, and the specification selection of cloth clamping sand blasting pipe has different requirements. The following small series will briefly introduce them to you: 1. Temperature: The selection should be based on the ambient temperature when the cloth clip sandblasting pipe is working. In case of high temperature, the temperature correction pressure shall be determined according to the working pressure and temperature correction coefficient of the cloth sanding pipe under high temperature to determine the correct pressure level. 2. Pressure: when selecting the cloth clip sandblasting pipe, check the nominal diameter and pressure gauge of the corrugated cloth clip sandblasting pipe according to the actual working pressure of the hose to determine whether to use the stainless steel mesh sleeve type. 3. Size: select the joint type, size of cloth sanding pipe and hose length according to the size of cloth sanding pipe. 4. Medium: determine the material of each part of the hose according to the chemical properties of the material medium transported in the cloth sanding pipe and the corrosion resistance of the hose material. 5. Status: According to the use status of the hose, refer to the correct use and installation method of the cloth clip sandblasting pipe and the length of the hose in the settlement compensation. Therefore, Oil resistant hose Price According to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe is, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe is selected.

production Oil resistant hose It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Oil resistant hose Price During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.

The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. production Oil resistant hose The vibration of the unit is transmitted to the ground hall through the bridge connecting the sand blasting hose pipe, and the noise value reaches 45dB. In such an environment, people always feel uncomfortable. After the improved design, sandblasting rubber pipes were connected in series on the connecting pipes, which not only absorbed some of the noise generated by the unit vibration, but also the noise generated by the fluid pulsation in the pipeline system. At this time, the noise value in the ground hall was only 33dB, greatly improving the environment in the hall. The movable cylinder on the vulcanizing press will move upward and downward for the need of loading and unloading the mold. After repeated reciprocating movements, the copper serpentine will suffer from fatigue fracture. Although it can still be used after repair, it will cause time loss if it is stopped for repair. Oil resistant hose Price Although it has good soft properties and strong fatigue resistance, it is weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not continue after several months of use. The good comprehensive performance of sand blasting hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often severe conditions such as fatigue, corrosion, vibration, compression, impact, etc. Under such circumstances, it is most appropriate to use sandblasting hose to compensate for the position movement of the pipeline.
