polyurethane wear-resisting Braided hose 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. Braided hose Price 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.
Jiangxi Braided hose The break of the sandblasting hose usually refers to the appearance and change of the crack of the sandblasting hose. The sandblasting hose has one or more cracks, but the cracks are neat. Another is that the internal bending cracks at the crack of the sandblasting hose are neat. The causes of different errors are different, and the treatment methods are also different. Therefore, in the process of using or protecting the sandblasting hose, the sandblasting hose should not be subject to changing torque. When installing the sandblasting hose, try to keep the axis of the two joints on the same plane to avoid twisting the sandblasting hose in use. Therefore, be careful with the application, and try not to make the sandblasting hose change excessively to avoid consumption. Sand blasting hose plays a very important role in the industry. Its inner rubber layer is added with carbon black, which can effectively eliminate static electricity and directly contact with compressed air and abrasives. The requirement for wear resistance is quite high. Once worn through, the reinforcement layer will be exposed, and the sand blasting hose will burst. The reinforcing layer of sandblasting hose is a pressure resistant layer, so wear-resisting Braided hose The material and layout of the reinforcement layer directly determine the pressure rating of the sandblasting hose. There are two common enhancement layers: cloth clip enhancement layer and surround enhancement layer. The sand blasting hose with an inner diameter of 50mm or more is mostly used in the construction occasions where the sand blasting pipe needs to be extended to reduce the pressure loss in the sand blasting hose and ensure the normal operation of shot blasting.
Although fire Jiangxi Braided hose 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. Braided hose Price 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.
Jiangxi Braided hose 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, 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; 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 substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first 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. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Braided hose Price When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.
wear-resisting Braided hose It is a key component of any hydraulic system. When they fail, everything will stop. The preventive maintenance of the metal sandblasting hose is very important and needs to be checked regularly in order to find problems before starting. This may include checking hose caps and fittings, and looking for other signs of leaks and impending hose failure. The more strict the hose inspection process, the more reliable your equipment will be. 1. Benefits of preventive maintenance of metal sandblasting hoses: preventive maintenance of metal sandblasting hoses and equipment is always better than reactive maintenance. One reason is that it can make your equipment run efficiently by solving problems before they fail and have a significant negative impact on the system. Contrary to what many people think, preventive maintenance means reducing downtime due to unexpected component and system failures. Attention to maintenance can also extend the expected life of equipment, maximize its economic value, and minimize potential safety hazards to personnel. Finally, preventive maintenance can reduce maintenance costs and unnecessary equipment procurement. Not participating in regular preventive maintenance can be an expensive decision. 2. Maintenance time of metal sandblasting hose: Braided hose Price Part of the preventive maintenance program for solid metal sandblasting hoses includes periodic inspection of metal sandblasting hoses. Fixed equipment shall be inspected every three months. For mobile equipment, hose inspection shall be conducted every three months or every 400 to 600 hours, whichever comes first.
