Qingdao Suction and discharge pipe 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 Suction and discharge pipe 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.
Qingdao wear-resisting In places that must be crossed or may rub with the mechanical surface when working, hose clamps or springs and other protective devices should be used to prevent the outer layer of the sandblasting hose from being damaged. Sand blasting hose shall be arranged to avoid heat source as far as possible and away from the performance of engine exhaust pipe. If necessary, sleeve or protective screen can be used to prevent the hose from being heated and deteriorated. When the sand blasting hose must be bent, the bending radius should not be too small, and should be greater than 9 times the outer diameter. There should be a straight line section greater than 2 times the outer diameter of the pipe at the joint between the rubber hose and the joint. How high-quality the products and equipment we use are, it is inevitable that there will be some large and small failures in the process of using them, which will more or less have a certain impact on our work. Just like the use of sandblasting hose, there are traces of its outer adhesive seam, problems must be solved, For this, we explained the following solutions: First, the used water cloth should be used according to the original elastic edge of the water cloth when it is reused. 2： When we wrap the water cloth around the seam of the sandblasting hose, we should apply sufficient and uniform pressure to the pipe body. 3. The water cloth with different widths should be selected according to the size of the outer diameter of the wrapped sandblasting hose (for hose with an outer diameter of less than 30mm, the width of the water cloth should not exceed 90mm). The overlapping width of the water cloth should be 3/5-2/3 of the width of the water cloth.
Qingdao Suction and discharge 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. Suction and discharge pipe Where can I find it? Hydraulic requirements 1. The maximum working pressure of wear-resistant sand blasting hose is 0.63MPa. 2.

The bursting pressure of the hose shall not be less than 4 times of the working pressure.
In the shipbuilding industry, radio industry, electrical industry, telecommunications industry, instrument industry, aviation industry, medical industry, etc., we often see acid and alkali resistant hose, then what is Qingdao Suction and discharge pipe What about? If you want to know more, please read down! Acid and alkali resistant silicone hose is a kind of pipe specially used for power equipment, which uses acid and alkali resistant silica gel as the main raw material and tightly wraps the pipe wall with electrical grade polyethylene spiral wire. Due to the chemical inertia of acid and alkali resistant silica gel, this kind of pipe has good acid and alkali resistance performance and electrical performance, and is commonly used in the production of wires, cables and lead wires in extreme acid and alkali environments. Also called: acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose, acid and alkali resistant silicone rubber hose. Features: 1. High temperature resistance (250-300 ℃) and low temperature resistance (- 40-60 ℃); 2. Good acid and alkali resistance. Physiologically stable, able to withstand repeated harsh and disinfection conditions, resistant to ozone aging, light aging, weather aging and ultraviolet radiation. 3. Small resilience and permanent deformation (no more than 50% at 200 ℃ for 48 hours), breakdown voltage (20-25KV/mm), ozone resistance and UV resistance. Suction and discharge pipe Where can I find it? Radiation resistance and other characteristics, 4. Good electrical performance, small change when exposed to moisture, water or temperature rise, even if the silica generated by short circuit combustion is still an insulator, which ensures that electrical equipment continues to work, so it is most suitable for making wires, cables and lead wires.
Qingdao Suction and discharge pipe Vulcanization of technical performance indicators is an important process to enhance the adhesive strength between rubber and reinforcement layer and make it a whole in rubber hose manufacturing, and also an important link to ensure and improve product quality. In order to obtain good pulse performance and service performance of steel wire reinforced rubber hose, in addition to reasonable structure and formula, it is necessary to ensure the compactness of vulcanized hose. In order to meet this performance requirement, the traditional vulcanization method is to wrap the water in water cloth on the semi-finished hose before vulcanization, make braided hose or steel wire for reinforcement and fastening, and vulcanize in batches with steam vulcanization tank. Since the performance requirements of medium and low pressure hoses are low, the rubber hose can also be directly put into the curing tank without fastening. Although water wrapped cloth vulcanization can also increase the compactness of the hose, its appearance is poor. In order to obtain the smooth outer surface of the hose, the lead coating vulcanization method is widely used at home and abroad. For decades, people have been using this method as an effective method to vulcanize and strengthen rubber hoses, especially high-pressure rubber hoses. So far, many domestic and foreign manufacturers are still using this method to produce rubber hoses. But the fatal disadvantage of this method is that it pollutes the environment. Suction and discharge pipe Where can I find it? The main control function of the air compressor station unit is to exhaust more air. According to different structures, it can be divided into full hose, cloth hose, steel braided hose, etc. According to different uses, it can be divided into air hose, water suction hose, water delivery hose, heat resistant hose, acid (alkali) resistant hose, oil resistant hose and special hose., It can be closed within the specified range.
