“ production rubber liner What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, rubber liner Price It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.

People buy in daily life production rubber liner Take it home for installation. It is obviously installed very well, but the spiral air duct will become loose for a long time, which gives most users a headache. So what is the problem with spiral air duct reinforcement? This is of course necessary. The following manufacturer of galvanized spiral air duct will give you a detailed introduction. 1. Reinforcement measures shall be taken for circular pipes (excluding spiral pipes) with a diameter greater than or equal to 80 mm, a section length greater than 1250 mm or a total area greater than 4 ㎡; 2. The side length of rectangular air duct is more than 630 mm, the length of pipeline insulation side is more than 800 mm, the section length is more than 1250 mm, or the plane area of one side of low pressure pipeline is more than 1.2 m2, and that of medium and high pressure pipeline is more than 1.0 m2, so reinforcement measures should be taken; 3. For reinforcement of irregular oval pipes, the reinforcement method of rectangular pipes shall be referred to. The spiral air duct manufacturer Hongyuansheng Electromechanical also has something to say: the reinforcement of galvanized air duct non-metallic air duct should also meet the following requirements: when the diameter or side length of the rigid PVC pipe is greater than 500 mm, the connection between the pipe and the flange should be equipped with stiffening plates, and the spacing should not be greater than 450 mm. The reinforcement of organic and inorganic FRP pipes shall be made of the same materials with the same anti-corrosion performance as the pipes themselves. rubber liner Price The manufacture of rectangular pipe elbows shall generally adopt concentric arc elbows with the curvature radius of the length inside and outside the plane. When other forms of elbow are used, and the plane length is more than 500 mm, the elbow deflector shall be set.

city in Hunan rubber liner Compared with rectangular duct, it is widely used in the ventilation industry. Why? Let's start with its advantages to solve this problem and make it clear. At the same time, through the following introduction, I hope you can know more about the spiral duct and make yourself more professional in this regard. Now let's understand the function of air duct: function 1: air supply and ventilation. It is used to transport fresh air and waste gas, exhaust harmful gas, and deliver outdoor fresh air to the room. Generally speaking, spiral air duct is good. If the environment is humid or corrosive, stainless steel shall be used to avoid rust and corrosion of air duct. Function 2: provide cold air. It is mainly used for central air conditioning, but thermal insulation materials need to be added on the air duct. Function 3: Exhaust lampblack: It is mainly used to exhaust kitchen lampblack in restaurants, hotels and other places. Generally, circular air ducts are used. Function 4: dedusting and bulk material conveying: in the factory workshop, the air duct is used for dedusting, and the spiral air duct can be used for conveying particles, such as foam plastic particles, because rubber liner Price The proportion of products is small. 1) Under the same plate thickness and pipe diameter, the strength of spiral air duct is higher. (2) Under the same section, the structural tension of spiral air duct is more reasonable, the stiffness is better, and the noise and vibration can be greatly reduced. (3) At the same length, the number of flange connections of spiral air duct is less, which can greatly improve the ventilation quality of the system.

city in Hunan rubber liner 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. rubber liner 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.

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. city in Hunan rubber liner 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. rubber liner 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.
