Although fire Zhengzhou Acetylene 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. Acetylene 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.

Zhengzhou Acetylene pipe Also called rubber hose for sand blasting. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. The common application fields are shipbuilding, machining, spraying industry, etc. Appearance of abrasion resistant sand blasting rubber hose: 1. Light abrasion resistant sand blasting rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, central fabric or cord reinforcement layer, medium rubber layer and outer rubber layer; 2. Heavy abrasion resistant rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, cloth clip or cord reinforcement layer, steel wire framework reinforcement layer, medium rubber layer Composition of outer rubber layer 3. The steel wire braided wear-resistant sandblasting hose is composed of black, yellowish or transparent wear-resistant rubber inner layer, single-layer or multi-layer steel wire braided reinforcement layer, medium rubber layer and outer rubber layer. Purpose Abrasion resistant sand blasting hose is a kind of material conveying pipe, which is mainly used for conveying solids containing particles such as particles, gravel, cement, quicksand, mud, gypsum, etc. It is suitable for various tunnel projects, tunnels, caverns and other engineering operations. The general working pressure is less than 12 bar, and the higher bursting pressure can reach 36 bar. Sometimes the vacuum rich negative pressure parameter is 0.8 bar 0.9 bar. Acetylene pipe company Hydraulic requirements 1. The maximum working pressure of wear-resistant sand blasting hose is 0.63MPa. 2. The hose shall be free from water seepage, local bulge, expansion and other abnormalities when conducting hydraulic test under twice the working pressure. Keep the pressure of anti-static hose for 1min, and the length change shall not exceed ± 0.8%, the outer diameter change shall not exceed ± 10%, and the torsion per meter shall not exceed 60 º. 3. The bursting pressure of the hose shall not be less than 4 times of the working pressure.

polyurethane high quality Acetylene 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. Acetylene pipe company 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.

Many people have never understood high quality Acetylene pipe It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Acetylene pipe company Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.

Acetylene pipe company The following recommendations contain a series of precautions to prevent items from aging to a greater extent during storage. 1. During storage, the rotating plan system shall be adopted to shorten the storage time of high-pressure braided hose as much as possible. If long-term storage cannot be avoided and the following recommendations cannot be followed, high-pressure braided hoses should be thoroughly inspected before use. 2. Physical storage conditions: The high-pressure braided hose must be stored without mechanical pressure, including excessive stretching, compression or deformation, and without contact with sharp or sharp objects. High pressure braided hoses should be stored on suitable supports or on dry ground. High pressure braided rubber tubes packaged as coils must be stored horizontally. High pressure braided rubber pipes shall not be stacked. If stacking cannot be avoided, the stacking height shall not cause permanent deformation of the high-pressure braided rubber pipe below. Pumping high-pressure hydraulic hose is a common high-pressure hydraulic hose. In order to ensure the operation safety of the pumped high-pressure hydraulic hose, the following small series will briefly introduce the correct use of the pumped high-pressure hydraulic hose: 1. Before each use of the high-pressure hydraulic hose, the surface of the high-pressure hydraulic hose must be evenly coated with soap liquid, which can play a non bonding role between the high-pressure hydraulic hose and the concrete, and play a lubricating role in the drawing process, It can greatly increase the reuse times of high-pressure hydraulic hoses. 2. Installation: first, insert the steel hinge wire into the inner hole of the draw tube to avoid extrusion deformation when pouring concrete. Then, pull out the high-pressure hydraulic hose coated with soap liquid from the prestressed hole and fix it in the correct position with a fixing ring. The spacing of the retaining rings is controlled by the suspension and is usually about 500 mm. high quality Acetylene pipe When connecting the high-pressure hydraulic hose, wrap both ends of the high-pressure hydraulic hose for one and a half weeks or two weeks with thin iron sheet or PVC pipe (vertical cutting), fix them with iron wire, and then seal both ends of the PVC pipe with tape to avoid entering the mortar.
