Qin'an Air compression hose Main impact: The air volume loss of the whole system is too large to meet the air volume requirements, and the power is seriously wasted. 1. If the stainless steel welded air duct system adopts the combined flange air duct, it may be that the seam, flange strip seam and hole seam are not sealed with sealant; The allowance of segment blanking seaming is greater than the specification requirements. 2. No embedded parts are set at the joint of brick structure air duct and metal air duct, or the sealing gap is too large or the joint is not tight. Countermeasures: 1. Button type seaming can be used for medium pressure air duct; Corner seam or joint corner seam shall be used at four corners of high-pressure air duct or clean system air duct. 2. Seams of stainless steel welded air ducts, joints without flange inserts and holes must be sealed with sealing paste to prevent air leakage. 3. During construction, embedded parts shall be set at the junction of brick, structural air duct and metal air duct as required, or the civil engineering unit shall cooperate to block and seal to ensure close connection. During the air duct anti-corrosion treatment, the next anti-corrosion treatment can be carried out after the previous paint is dried; It is strictly forbidden to work without certificate. The duct type air outlet is a central air conditioning terminal air supply system that integrates the functions of air outlet, air supply pipeline, static pressure box, thermal insulation material, air valve, etc. Air compression hose Price Calculation of air duct size of stainless steel welded air duct: the equal damping method (equal pressure method) is a convenient calculation method, which is suitable for many occasions.

We are all denominators. Why treat ourselves as molecules. But I think we Air compression hose Price The mass of is absolutely the molecule in the same industry. From raw materials, the general manager is responsible for the purchase of raw materials. Raw materials can only enter the factory after passing the inspection. Because it is the boss's own purchase and inspection, there is no buyer to take kickback, which increases the cost of raw materials and reduces the quality of raw materials. Speaking of the manufacturer's production process, it is difficult to find the second advanced mixer equipment among the new sand pumping hose manufacturers in 2019. It ensures that our glue is more uniform. This ensures the quality of our sand pumping hose. About 70% of sand pumping hose is manual work, and the production technology experience of workshop workers largely determines the quality of our sand pumping hose. 70% of our workshop workers have more than 7 years of production wear-resisting Air compression hose Experience.

When I was just doing business, I received a 3 page quotation, and I patiently sorted it out for about 2 days. Finally, there was no news. Now I have been doing business for more than 10 years. Sometimes I can accurately judge the order rate of this order simply by looking at the inquiry list. The real heart of the words lies in the customers who make good deals.

Let's take a look today Qin'an Air compression hose How should the maintenance work be done? Firstly, the thickness of galvanized air duct splice plate shall be within the range specified in various specifications. If it is less than the thickness, it is easy to have defects such as cracking and wrinkling due to significant increase of bending force, abnormal damage of forming roll, overload of transmission system, boring, etc. Secondly, in the dedusting system: galvanized air ducts can be used for the collection and transportation of dedusting devices. In terms of air exhaust system: there is a large amount of smoke in the dining room, dining room and hotel kitchen, which needs air exhaust. The galvanized pipe is more appropriate, with good strength, economy and practicality. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials, and the surface is beautiful. In bulk material transportation: in the pneumatic conveying system, some materials with fine loose particles can be transported by galvanized pipes, which has low cost and good effect. In the ventilation system: fresh air is supplied and discharged, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. The strength of stainless steel plate is greater than that of ordinary steel plate. When stainless steel plate is used for seaming, first of all, a forming test should be carried out to avoid overloading of equipment and excessive wear or mechanical problems. Due to the poor plasticity of aluminum plate, it is easy to crack when biting into forming. Forming test shall be conducted before construction. The last point is that the protection and decoration of the galvanized layer of the galvanized air duct can be significantly improved after passivation treatment, dyeing or brushing light protective agent. and Qin'an Air compression hose The fire prevention function of is mainly reflected in that it is nonflammable, but it should be noted that whether the insulation layer is burned depends on the material. We recommend that galvanized air duct materials use nonflammable insulation materials such as centrifugal glass wool.

What is stainless steel spiral duct? Air compression hose 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 wear-resisting Air compression hose 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.

Air compression hose Price Precautions ① The acid and alkali resistant rubber hose used shall not only be oil resistant, but also be pressure resistant, heat resistant, cold resistant, wear resistant and aging resistant. ② The rubber hose should not be too long or too short, generally 1.4 meters. ③ The interface is tight and can be fastened with thin iron wire or clip to prevent falling off and air leakage. ④ It is forbidden to pull acid and alkali resistant rubber hose from one room to another or through walls, floors and floors to prevent accidents caused by rubber hose breaking and falling off. ⑤) The acid and alkali resistant rubber hose should be placed in a place where it can be seen frequently, so that it is easy to detect leakage. Check whether the rubber hose leaks after each bottle change. ⑥ Do not replace acid and alkali resistant rubber hose with universal rubber hose. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose; The cloth clamping hose needs to use a molding machine that wraps the adhesive tape on the inner adhesive layer; When forming the suction hose, first wrap the metal spiral wire and then wrap the inner rubber; Special fabric knitting machine or winding machine shall be used for knitting and winding hose; Knitting machine is required for knitting hose. Qin'an Air compression hose The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The acid and alkali resistant hose manufacturer said that the processing method of the skeleton layer and the hose molding equipment are different for different structures and different skeletons.
