I believe everyone is familiar with production Sandblasting hose Relevant application knowledge of products. It is understood that at present, this product is mainly used for mining hydraulic support and oilfield development. It is applicable to engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, mechanization of various industrial departments, water-based liquids, etc. And liquid transmission. Its relatively high working pressure can reach 70-120 MPa. In order to achieve better application effect, what problems should be paid attention to when using high-pressure braided hose? 1. The bending radius shall not be less than the given bending radius to prevent damage to the hose skeleton or premature failure due to excessive tension. 2. Select the type and specification of the hose correctly according to the use conditions, and do not misuse or replace it. 3. When using high-pressure braided hose, the pressure should be adjusted slowly and evenly to avoid sudden pressure increase and damage to the pipe body. 4. When the work site changes, it should be removed from the ground without dragging, so as to avoid the skeleton layer being corroded after scratching the outer glue. 5. After delivering corrosive liquid, the interior should be cleaned to prevent residues from corroding the pipe body for a long time, or select corresponding series of products. When storing high-pressure braided rubber hoses, depending on the type of rubber used, Sandblasting hose Price Note which conditions typically change over time. However, due to several factors or a combination of several factors, this change may accelerate, and other materials used to strengthen high-pressure braided hoses may also be adversely affected by improper storage conditions.

Changchun Sandblasting hose It is a kind of hose that can be used for sand pumping and sand suction produced with high abrasion resistant rubber. It is often used in sand blasting industry, cement, steel, minerals and other industries, but it is mainly used in river dredging, slurry transportation in mines, sand digging and sand taking and other industries to transport sharp granular solids or solid-liquid mixtures. Its product structure is composed of high wear-resistant layer, reinforced water pipe layer, skeleton steel wire and outer rubber. Today, Myers will introduce the application field of wear-resistant sand absorption rubber pipe. When the wear-resistant sand suction rubber pipe is applied in the mine pit, it is necessary to set a floating boat equipped with a sand pump in the mine pit, and use the floating sand suction rubber pipe to connect with the sand pump. The floating boat will float up and down with the rise and fall of the water level. It is required that the pipe body has good flexibility and good tear resistance and bending resistance. The offshore pipeline is connected by non floating sand suction hose until the pulp transportation destination. The overall pipeline is divided into two parts, one for surface use and the other for onshore use. The main raw material of these two kinds of hoses is high abrasion and corrosion resistant rubber, and cord reinforcement layer and steel wire skeleton layer are added in the pipe wall to ensure the pressure resistance and tear resistance of the hose. The connection mode is vulcanized flange connection, that is, the flange and the hose are a whole, so there is no need to worry about the flange falling off. Floating sand suction hose used on the water surface. This kind of hose is required to float on the water surface. Due to the large drop of the mine (100 meters) and the long conveying distance Sandblasting hose Price The hose shall have high pressure resistance, and the design pressure is 25 kg/cm2 according to the calculation. It should be considered that the floating ship will move up and down with the rise and fall of the water level and the wave will cause lateral displacement. Its internal structure is the same as the sand suction hose used offshore, except that a floating body is installed outside the hose.

As production Sandblasting hose As an important part of sand blasting machinery, its safety plays a vital role in the safety of equipment operation. The following will briefly analyze the precautions in the use of high-pressure sandblasting pipe: I. Pipe inner diameter: inner diameter of high-pressure sandblasting pipe. 2、 Attention shall be paid to the following items in the use and design of high-pressure sandblasting pipe: 1. The bending radius of high-pressure sandblasting pipe shall not be too small, and generally shall not be less than the value specified in the assembly technology of high-pressure sandblasting pipe. The joint between the high-pressure sandblasting pipe assembly and the pipe joint shall have a straight section, and its length shall not be less than twice the outer diameter of the pipe. 2. The length of high-pressure rubber hose assembly shall consider that the high-pressure rubber hose will shrink and deform after introducing pressure oil. Generally speaking, the shrinkage rate is 3~4 times of the pipe length. When installing the high-pressure rubber hose assembly, it is not allowed to bear tension. 3. During installation, the high-pressure sandblasting pipe assembly shall be free from torsional deformation. Sandblasting hose Price The connecting shaft of shall be placed in the moving plane as far as possible to avoid damaging the high-pressure sandblasting pipe when both ends move with each other. 4. High pressure resistant sand blasting pipe shall avoid contact and friction with mechanical sharp corners to avoid damaging the pipe. Safety measures: to ensure the safe and reliable use of high-pressure sandblasting pipe assembly.

Due to the limitation of spatial location conditions, production Sandblasting hose 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. Changchun Sandblasting hose 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.

Changchun Sandblasting 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. The odorless butyl reclaimed rubber can be used for the consumption of odorless rubber sandblasting pipes. In addition, odorless hb isoprene reclaimed rubber can also be used for consumption of odorless rubber sandblasting pipes. In actual consumption, the raw materials of odorless isoprene reclaimed rubber (PP reclaimed rubber) are isoprene unvulcanized composite rubber and isoprene bottle stopper. They have strong viscosity, aging resistance and temperature resistance, and are ideal for odorless hose consumption to ensure quality and reduce costs. Pay attention to the vulcanization of odorless rubber sand blasting pipe. as everyone knows, Sandblasting hose Price The design of vulcanization system of reclaimed rubber products directly affects the quality of rubber products, and the odorless rubber sand blasting pipe of reclaimed rubber is no exception. When using reclaimed rubber to consume odorless rubber sand blasting pipe products, vulcanizing agent, accelerator and other additives must be combined with odorless additives such as accelerator STT and accelerator D; When vulcanizing the rubber of odorless rubber sand blasting pipe, it is better to vulcanize at low temperature for a long time, which will cause full reaction to the rubber.
