Due to the limitation of spatial location conditions, production Large diameter suction pipe The installation stress of can often bring various difficulties to the installation work: formed pipes cannot be installed; When you bend down, you are about to come. If you make do with pipes, local cold correction will inevitably occur. According to the size of the pipeline and the specific situation on site, the cold correction amount varies from several millimeters to tens of millimeters, some as high as hundreds of millimeters. Practice has proved that the greater the quantity, the higher the internal stress. These residual installation stresses in the rubber sand blasting pipe are undoubtedly huge hidden information. The lubricating oil duct of a certain type of engine bearing was broken for many times due to excessive installation stress in actual operation. Because it can be bent at will, the internal stress generated by bending under the condition of rated bending radius is very small, which brings great convenience to the installation work, and also plays a certain role in ensuring the safe operation of the rubber sand blasting pipe. This is the main reason why some rubber sand blasting pipes must be used. Since it is necessary to load and unload the mold, the movable cylinder on the vulcanizer will move up and down. After repeated reciprocation, the copper serpentine tube will undergo fatigue fracture. Although it can continue to be used after repair, stopping for repair will cause time loss. Henan Large diameter suction pipe Although it has good flexibility and strong fatigue resistance, it is also weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not be used after several months. The good comprehensive performance of rubber sand blasting pipe is fully reflected here.
Henan Large diameter suction 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. Large diameter suction pipe Where can I find it? 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.
The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. production Large diameter suction 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. Large diameter suction pipe Where can I find it? 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.
polyurethane production Large diameter suction pipe Maintenance measures; Cleaning: It is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber tube must be inspected to ensure that there is no structural damage. Pressure: If the rubber pipe is under great pressure during use, or the outer layer of the rubber pipe will contact with the conveyed liquid for a long time, it is recommended to conduct a hydrostatic test. Due to the natural characteristics of rubber, the physical properties and performance levels of all rubber products will change. This change usually occurs over time, depending on the type of rubber used. However, changes may also accelerate due to several factors or a combination of several factors. Other materials used to reinforce rubber tubing may also be adversely affected by improper storage conditions. Detailed step 1. Polyurethane sand blasting pipe mandrel: the mandrel is usually pulled backward, mainly to increase the firmness of the connection between the mandrel and the hose. After the spindle barb processing is completed, the barb tip must also be passivated, otherwise the barb tip will pierce the lining material of the high-pressure rubber tube during the buckling process. Large diameter suction pipe Where can I find it? Even if the high-pressure rubber pipe joint is firmly buckled, if the inner layer is damaged, high-pressure water will leak from the buckle. 2. Polyurethane sand blasting pipe sheath: the sheath is generally in the form shown in the figure, the wall thickness should be moderate, and the internal rectangular tooth height should not exceed 2mm, that is, (d-d) should not exceed 4mm.
Although fire Henan Large diameter suction 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. Large diameter suction pipe Where can I find it? 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.
