Yinchuan Oil 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 Oil hose company 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.

People buy in daily life production Oil hose 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. Oil hose company 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.

Yinchuan Oil 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. Oil hose company 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.

For the woodworking industry, many users production Oil hose Not unfamiliar, this is an industrial dust collector used on woodworking carving machines, mainly used to absorb wood chips, wood ash, etc. At present, there are many kinds of woodworking vacuum tubes on the market. In the past few years, major furniture factories used PVC steel wire hoses with flat ends. In recent years, more and more enterprises have replaced cheap PVC steel wire hoses with more wear-resistant and durable pu steel wire expansion tubes. Some of the former take a few days or a month, while some of the latter take a few months or a year, They are also steel wire hoses. Why is the service life gap so far? First of all, you may have the impression that many PVC hoses have a very bad smell. This kind of hose is often used in daily life. Because the raw material itself is very cheap, the price of the finished product is also very low. For example, only a dozen yuan a piece. Think about the price of PVC raw materials, which is generally 8-15 yuan a kilogram, And most businesses will not use expensive PVC raw materials, Oil hose company The woodworking vacuum tube produced in this way has a very strong smell, not only unpleasant, but also many times the product can not even achieve environmental protection. However, the current updated product, pu steel wire telescopic tube, is a large woodworking furniture factory. An expensive woodworking carving machine uses a cheap vacuum tube with a very smelly smell, which has much to do with the overall style.
