Oil hose Price 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. wear-resisting Oil hose 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.
wear-resisting Oil hose Or PVC steel wire spiral reinforced pipe. The commodity is made of high-quality PVC plastic raw materials. PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework. The inner and outer tube walls are clear, lubricated, free of bubbles, and the fluid transportation is clearly visible. Silicone fiber tube is resistant to low concentration of acid and alkali, high elasticity, not easy to age, and has a long service life. Resistant to high pressure and can be kept intact under high pressure and vacuum. PVC steel wire pipe is made of new PVC reinforced materials, and has made great progress in compressive strength and hardness. The main production method of silica gel steel wire pipe is multiple production method. The main types of steel wire pipe in shopping malls include high pressure steel wire pipe, low pressure steel wire pipe, steel wire skeleton pipe and Tongming steel wire pipe. The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Oil hose Price After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.
wear-resisting Oil hose 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Oil hose Price It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.
Whether in the process of purchase or use, wear-resisting Oil hose The quality of all needs to be checked regularly. During the inspection, the following items should be noted. 1. Standard size and actual error of high-pressure rubber hose: because the inner diameter and outer diameter of high-pressure sand blasting pipe and the outer diameter of the skeleton layer will shake, if the shaking amplitude exceeds the allowable limit, the balance of the buckling amount of the sand blasting pipe joint cannot be guaranteed, and the quality of the sand blasting pipe assembly cannot be guaranteed. Therefore, for the sand blasting pipe selected for the production of sand blasting pipe assembly, it is necessary to strictly check whether the inner diameter and outer diameter of the skeleton layer meet the requirements, and the requirements for the outer diameter error can be appropriately relaxed. 2. Wall thickness error of high-pressure hose: due to the local pain of the rubber layer in the high-pressure sandblasting pipe and the influence of the overlapping width of the rubber layer of the high-pressure sandblasting pipe quality inspection center between the skeleton layers, the wall thickness error of the sandblasting pipe may be too large. If the wall thickness error exceeds the allowable range, it will affect the tightness and pull-out strength of the connector, and even cause some deflection (tilting head) of the hose assembly connector. Quality inspection of high-pressure sand blasting pipe Therefore, the wall thickness error of sand blasting pipe should be strictly controlled. Generally, the rubber hose with wall thickness error exceeding 0.5mm shall be selected stably. 3. Adhesion between each layer of high-pressure rubber hose: high-quality high-pressure sand blasting pipe shall have prominent integrity, that is, the quality inspection of high-pressure sand blasting pipe shall have high adhesion between each structural layer, and the adhesion between each adhesive layer shall become an integrity. Only in this way can we meet various technical requirements in the process of joint installation and fastening, and only in this way can we ensure the quality inspection requirements of high-pressure sand blasting pipes for sand blasting pipe assembly. Therefore, Oil hose Price It is necessary to control the adhesive force between each layer of the rubber hose not lower than that specified in the technical standard, and the rubber hose with high adhesive force shall be selected as far as possible to produce the rubber hose assembly.
Zhengzhou Oil hose It is one of the most common rubber products in life, used to transport various gases and liquids. Natural rubber, synthetic rubber and reclaimed rubber in rubber products can be used for the consumption of rubber sand blasting pipes. When reclaimed rubber is used to consume odorless rubber sand blasting pipe, care must be taken in selecting reclaimed rubber and formula design to meet the performance requirements of odorless rubber sand blasting pipe. When using recycled rubber to consume odorless rubber sand blasting hose, what problems should we pay attention to? The selection of reclaimed rubber for odorless rubber sandblasting hose is the basis for determining the quality of rubber, whether it is environmental protection rubber products or various odorless rubber products. When using reclaimed rubber to consume odorless hose, choosing odorless reclaimed rubber is the top priority. Application of odorless reclaimed latex, odorless reclaimed tire rubber, odorless reclaimed nitrile rubber and odorless reclaimed ethylene propylene rubber in reclaimed rubber products.
