1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Sandblasting pipe Price Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Harbin Sandblasting pipe The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
one Harbin Sandblasting pipe When using, the talcum powder on the inner wall of the hose must be blown clean to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with acids, alkalis, oils and other organic solvents that can damage the hose. The storage temperature shall be - 15~40 ℃, and the distance from the heat source shall not be less than 1m. 3. According to the national standards, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; The acetylene hose is black, the working pressure vessel is 0.3MPa, the inner diameter of the hose is 8mm, and the outer diameter is 16mm. 4. The gas cutting operation requires a large oxygen output, so the valves of the gas cylinder (or oxygen pipeline) connected to the high pressure end of the oxygen meter should be fully opened to ensure adequate flow and stable pressure. The low pressure gauge has indicated the working pressure, but the pressure drops suddenly when using oxygen. At this time, it is easy to backfire and may backfire into the oxygen hose to cause explosion. 5. Oxygen hose and acetylene hose shall not be mixed or substituted with each other, and oxygen and hose shall not be used to blow away the blockage of acetylene hose. At the same time, it is necessary to check and eliminate the defects such as gas leakage and blockage of the welding torch at any time to prevent the formation of oxygen and acetylene mixture in the hose. It should be pointed out that the hose color specified in the national standard is opposite to that specified in the international standard (ISO) (oxygen hose is black, acetylene hose is red). At the same time, it is different from the original ministerial standard (HG4-605-66) that oxygen hose is red and acetylene hose is green. Before 1966, domestic oxygen hose was black or green and acetylene hose was red. thus Sandblasting pipe Price It causes inconsistency between the understanding and habits of the supply department and the user, and is easy to cause accidents due to the mixing and substitution of rubber hoses. At present, it should be emphasized that unified understanding and use should be carried out in accordance with the provisions of national standards, and attention should be paid to distinguishing the rubber hoses of imported equipment.
The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. wear-resisting Sandblasting pipe 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. Sandblasting pipe 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.
Harbin Sandblasting pipe It is widely used in mining, chemical industry, construction and iron and steel fields. At present, 90% of ball mills, rod mills and moistening mills on the market still use manganese steel cylinder liners, and the manganese steel material consumed on liners alone every year is more than one million tons. The emergence of rubber liners is favored by many big customers in the ball mill field. What are the indexes that affect the rubber lining plate of the ball mill? 1. Conditions of ball mill use scenario The feeding particle size of ore also plays an important role, so a good ball mill rubber lining plate will be designed according to the size of the customer's mill, feeding particle size, and steel ball diameter. Select the rubber formula suitable for customers, and carry out mapping, design, testing and processing. 2. Rubber formula and processing technology: The rubber material and formula directly affect the performance of the rubber lining plate of the ball mill. Wear resistance is a key factor. It is impossible to determine how long its service life is because of the impact of industrial and mining conditions. The second is corrosion resistance. This is the characteristic of the formula, so even if the appearance is the same, the performance is an advantage. Do not buy for cheap. 3. Regular maintenance: everyone knows that the rubber lining plate of the ball mill is fixed to the cylinder by means of T-bolts, so it is also very important to regularly check the tightness of the bolts and the wear of the rubber strips inside the cylinder. In order to avoid damaging the rubber lining plate of the cylinder and the cylinder of the ball mill when the lifting strip is worn out, the gain is not worth the loss. Sandblasting pipe Price One of the advantages of the manganese steel lining plate is that the replacement is simple and only needs two people to operate, and it can be replaced wherever it is broken. This is an advantage that the manganese steel lining plate does not have.
Harbin Sandblasting pipe 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. Sandblasting pipe 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.
