one Lanzhou Peristaltic pump 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 Peristaltic pump pipe company 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.

For the woodworking industry, many users wear-resisting Peristaltic pump pipe Not unfamiliar, this is an industrial dust collector used on woodworking carving machines, mainly used to absorb wood chips, wood ash, etc. At present, there are many kinds of woodworking vacuum tubes on the market. In the past few years, major furniture factories used PVC steel wire hoses with flat ends. In recent years, more and more enterprises have replaced cheap PVC steel wire hoses with more wear-resistant and durable pu steel wire expansion tubes. Some of the former take a few days or a month, while some of the latter take a few months or a year, They are also steel wire hoses. Why is the service life gap so far? First of all, you may have the impression that many PVC hoses have a very bad smell. This kind of hose is often used in daily life. Because the raw material itself is very cheap, the price of the finished product is also very low. For example, only a dozen yuan a piece. Think about the price of PVC raw materials, which is generally 8-15 yuan a kilogram, And most businesses will not use expensive PVC raw materials, Peristaltic pump pipe company The woodworking vacuum tube produced in this way has a very strong smell, not only unpleasant, but also many times the product can not even achieve environmental protection. However, the current updated product, pu steel wire telescopic tube, is a large woodworking furniture factory. An expensive woodworking carving machine uses a cheap vacuum tube with a very smelly smell, which has much to do with the overall style.

The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. wear-resisting Peristaltic pump 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. Peristaltic pump pipe company 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.

Although fire Lanzhou Peristaltic pump pipe Explosion proof pipe) can be compressed and stretched, but if the installation position is incorrect, it will break quickly and reduce the service life. The sandblasting hose can be installed horizontally, vertically or obliquely. The most ideal condition is vertical installation. At the same time, avoid installing near the wheel, and install baffle if necessary. Generally speaking, the flame spraying metal sand blasting hose (explosion-proof pipe) can be divided into three lengths: the first is the compression length, that is, the length of the sand blasting hose when it is compressed to the limit position; The second is the installation length, that is, the length of the sandblasting hose when it is in the middle of half of the maximum displacement. The third type is the stretching length, that is, the length when the sandblasting hose is stretched to the maximum limit. When installing the sandblasting hose, the sandblasting hose should be in the middle position, which is called the installation length. When installed at this position, the sandblasting hose can move in two directions when bearing axial load. Otherwise, if it can only move in one direction, its strength will be affected and its service life will be reduced. In the actual installation process, considering that measuring the length of the sandblasting hose with a ruler according to the calculation results may affect the production efficiency, some foreign manufacturers directly install the ruler on the sandblasting hose, and cut the ruler after installation. From the structural point of view, the metal flame spraying metal sandblasting hose (explosion-proof pipe) is composed of strip and tube parts, which can form annular flame spraying metal sandblasting hose bellows and spiral flame spraying metal sandblasting hose bellows. Peristaltic pump pipe company Just because the corrugated pipe of the fire sprinkler metal sandblasting hose formed by this article always has a certain length of brazing or welding buckles and fire sprinkler metal sandblasting hose joints, the residues of the working medium often accumulate in these places, and the cleaning test and mechanical impurities in the working medium will deposit down to pollute the inner cavity. Therefore, its use reliability is relatively poor.
