Xining Oxygen band The entry threshold is low, the industry market is mixed, and small enterprises with small scale, lack of core competitiveness and low technical level can be seen everywhere. Most of these enterprises lack brand awareness, and there are many brand names and unlicensed products. It is difficult to form enterprise influence through brands, and it is more difficult to improve product added value through brands. If the metal hose wants to take the road of high-end, it must improve both inside and outside. A good brand image promotion and influence building can certainly provide a strong driving force for the development of enterprises, but the source of this driving force lies in the high quality of the metal hose products themselves. Tongfeng Metal Hose said that in the future, domestic metal hose products will focus on high precision, high efficiency, high firmness, multi-function, multi specification, multi variety standardization, serialization and generalization to show their characteristics. One of the main reasons why China's metal hoses have been in the low-end state for a long time is the lack of independent research and development of products. On the one hand, the homogenization competition is serious. In order to win consumers, metal hose enterprises have long focused on low-cost competition and low price shopping. As a result, many enterprises only focus on the production and marketing of low-end products, ignoring the upgrading and innovation of product technology. on the other hand, Oxygen band Price ZHUANLI's weak awareness of protection and the serious phenomenon of technology plagiarism and infringement in the industry make the technology cost invested by many enterprises more than worth the cost, which has seriously hit the enthusiasm of metal hose enterprises for innovation.

The hard core method adopts the core extrusion process to extrude the inner rubber tube blank, which directly uses the extruder to cover the inner rubber tube blank on the iron core, instead of the traditional casing process, and simplifies the process flow. Xining Oxygen band The billet forming adopts the process method of intertwining outer film and steel wire braiding forming. Similar to wrapping water wrapped cloth, the overlapping width is 1/2 of the film width. This process method can replace the method of wrapping outer film by extruder or by hand, reducing energy consumption and cost. We all know that the reinforcing layer and reinforcing layer of the rubber hose are the main force bearing parts, which are used to bear the load pressure. The factors determining the stress condition of the reinforced layer of the rubber hose are determined by the tension of the braided steel wire and the braiding angle. The high-speed steel wire hose braiding machine developed by our factory has introduced the advanced technology of foreign braiding production lines, and integrated the characteristics of domestic braiding machines. It integrates the advanced functions of hydraulic brake hose braiding production line, such as horizontal mechanical transmission, automatic lubrication, and so on, to develop equipment with high productivity and high degree of automation. The range of braiding diameter can be achieved Ф 6— Ф 25 Long core rubber hose (reinforcement layer). It fills the gap of domestic knitting production equipment, which can be widely used in rubber and plastic hose, rubber hose (reinforcement layer) knitting production equipment. The structure of high-pressure rubber hose is composed of four parts: inner liner, inner rubber layer, skeleton layer, middle rubber layer and outer rubber layer. Oxygen band Price In case of direct contact with the conveying medium, the synthetic rubber with good medium resistance, high tensile strength, high constant tensile stress, small compression permanent deformation and easy processing is usually selected. In order to meet the use requirements of strong polar medium resistance, the inner liner is composed of polytetrafluoroethylene layer and rubber layer, and a layer of film or adhesive is added on the surface of the inner liner to improve the adhesion with the skeleton material.

What is stainless steel spiral duct? Oxygen band Price The products are mainly used to connect the air flow between two places and play the role of ventilation. There are three types of galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Here we mainly talk about the stainless steel spiral air duct, and briefly analyze the reason why it is widely used in villas. The so-called stainless steel air duct is strictly a kind of air duct processing technology, also known as spiral seamed thin-walled tube. The best quality is the thin-walled tube with spiral seamed made of metal strips. Because the applied material is metal, it is also called spiral seamed metal tube. It was first used in the military industry of western countries, such as ships, ship ventilation, air conditioning systems, and later used in trains Subway, mine and other civil facilities. By 2000, according to statistics, 95.6% of office buildings, shopping malls and subways in the United States had applied spiral air ducts. In civil residential buildings, 72.5% of central air conditioners use spiral air ducts. Since the mid-1990s, China has introduced this technology into the shipbuilding industry. With the rapid development of China's economy, the use of central air conditioners has increased year by year, and the quality of auxiliary products for exhaust and air supply has been continuously improved. Spiral air ducts have been widely used in some villas. (1) Product standardization: The production of spiral round air duct fittings (pipe fittings and joints) has been highly automated, systematic, and has industrialized quality control. It is well known that the wind resistance of circular duct is much smaller than that of rectangular duct. (2) Easy to install. The installation of spiral air duct significantly reduces the connection points between pipes and minimizes the leakage at the joint of pipe fittings. The typical spiral air duct is 3~6m long, while the typical rectangular air duct is only 1~1.5m long; The connection of two spiral air ducts requires only one pipe connector, while the connection of traditional rectangular air ducts often requires a completely independent double flange system. (3) Usually only small installation space is required: the same high quality Oxygen band The circular pipe with a diameter of 200mm in the installation space can replace 250 × 150mm rectangular pipe. On the premise of not increasing additional installation space, several parallel circular pipes can replace flat rectangular pipes.

Xining Oxygen band It is widely used in mining, chemical industry, construction and iron and steel fields. At present, 90% of ball mills, rod mills and moistening mills on the market still use manganese steel cylinder liners, and the manganese steel material consumed on liners alone every year is more than one million tons. The emergence of rubber liners is favored by many big customers in the ball mill field. What are the indexes that affect the rubber lining plate of the ball mill? 1. Conditions of ball mill use scenario The feeding particle size of ore also plays an important role, so a good ball mill rubber lining plate will be designed according to the size of the customer's mill, feeding particle size, and steel ball diameter. Select the rubber formula suitable for customers, and carry out mapping, design, testing and processing. 2. Rubber formula and processing technology: The rubber material and formula directly affect the performance of the rubber lining plate of the ball mill. Wear resistance is a key factor. It is impossible to determine how long its service life is because of the impact of industrial and mining conditions. The second is corrosion resistance. This is the characteristic of the formula, so even if the appearance is the same, the performance is an advantage. Do not buy for cheap. 3. Regular maintenance: everyone knows that the rubber lining plate of the ball mill is fixed to the cylinder by means of T-bolts, so it is also very important to regularly check the tightness of the bolts and the wear of the rubber strips inside the cylinder. In order to avoid damaging the rubber lining plate of the cylinder and the cylinder of the ball mill when the lifting strip is worn out, the gain is not worth the loss. Oxygen band Price One of the advantages of the manganese steel lining plate is that the replacement is simple and only needs two people to operate, and it can be replaced wherever it is broken. This is an advantage that the manganese steel lining plate does not have.
