production Acetylene tape The thickness of the seaming plate shall be within the regular range of products of various specifications. If it is less than the thickness, cracks, wrinkles and other defects are likely to occur during seaming; If it is larger than the large thickness, as the square of the plate thickness is proportional, the bending force will significantly increase, which will cause abnormal damage to the forming roller, overloading of the transmission system, and stuffiness. In dust removal system: galvanized air duct can be used for collection and transportation of dust removal device. In the oil smoke exhaust system: there are a lot of oil smoke in restaurants, restaurants and hotel kitchens, which need to be discharged. The galvanized air duct is suitable, strong, economical and practical. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials inside, and the surface is beautiful. In bulk material transportation: pneumatic transportation system, some finer and looser material particles can be transported by galvanized air ducts, with low cost and good effect. In the ventilation system: supply fresh air and exhaust gas, exhaust harmful gas outdoors, and send outdoor fresh air indoors. The strength of stainless steel plate shall be higher than that of ordinary steel plate. Before seaming with stainless steel plate, forming test shall be carried out first to avoid overloading the equipment and causing excessive wear or mechanical trouble. Due to the poor plasticity of the aluminum plate, it is easy to crack during the forming of the seaming. The forming test should also be carried out before construction. At the same time, because the aluminum plate is lack of elasticity, the aluminum plate air duct cannot be subject to snap seaming. After the zinc coating of galvanized air duct is passivated, dyed or coated with light protection agent, Acetylene tape Price It can obviously improve its protection and decoration. The fireproof function of galvanized air duct is mainly reflected in that it is incombustible, but one thing needs to be noted is that whether its insulation layer is burned depends on the material. We suggest that the galvanized air duct should be made of incombustible insulation materials such as centrifugal glass wool.

We all know Acetylene tape Price The noise pollution in industrial production is very serious, and noise pollution is also an important factor affecting workers' enthusiasm for production. Ball mills were once a major source of noise in mining equipment. In order to reduce the noise generated by ball mills, protect the physical and mental health of workers, improve workers' enthusiasm for production, and create greater profits for the company, Through the efforts and research of domestic and foreign industry experts, the ball mill liner has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber liner and the manganese steel liner of the ball mill is far less than the manganese steel liner when the technical parameters are up to standard. According to the data provided by the noise monitoring station and the concentrator, We analyzed the noise intensity and the economic benefits: the domestic ND2 precision sound level meter and octave filter were used for detection, and the sound level meter was calibrated by the provincial sound level meter measurement and verification station; There is no sound insulation room in the ball mill workshop. The monitoring points are arranged according to the position of the ball mill and the flow of workers to observe the mechanical operation, 2m away from the sound source. One monitoring point is respectively set on the left and right of the east and west of the workshop and in the middle of the two ball mills. The measurement method is in accordance with the Noise Detection Specification for Industrial Enterprises. As the noise in the workshop is continuous and steady, sound level A is used as the evaluation basis. The rubber lining plate is manufactured by Hainan Rubber Lining Plate Factory according to the ball mill shell structure and the original manganese steel lining plate specification (1.4mx0.74mX0.07m). Baoji Acetylene tape First, take out the manganese steel lining plate in the ball mill barrel, and then install the rubber lining plate in the barrel in turn (front and back). Each ball mill is installed with 48 pieces. First, use the pressure strip to compress, and then use the screws to fix the rubber lining plate on the ball mill barrel, so as to prevent falling off when rotating. The noise intensity of the ball mill workshop with manganese steel liner is 94-103dB (A), while the noise intensity of the ball mill workshop with rubber liner is 87-92dB (A), and the noise reduction difference is 7-11dB (A). The rubber liner has good noise reduction effect.

Baoji Acetylene tape The quality is closely related to the material selection and the manufacturing process. 1. The galvanized air ducts of different specifications are made of plates of different thicknesses according to the specification requirements. On the basis of being familiar with the size and layout of the air duct in the drawing, skilled technicians will set out and cut the material to ensure that the air duct production and installation meet the relevant standards. 2. The galvanized sheet air duct flange will be made uniformly according to the series of specifications specified in the drawing. In addition, the bolt holes of the flange will be punched at a fixed distance with a punch and a mold. The forming welding of the flange will also be positioned with a special mold to ensure that the air duct flange of the same specification has interchangeability. Compared with the traditional galvanized iron pipe made by hand, the round galvanized air pipe made by mechanism has the following advantages: (1) The round galvanized air pipe has good sealing performance. (2) Both strength and rigidity are good. (3) The ventilation resistance is small, the ventilation noise is small, and the round pipe is better than the square pipe. (4) The galvanized air duct is easy to install and has few connection points. (5) Circular production Acetylene tape High grade, beautiful appearance. Galvanized spiral duct is very suitable. Generally, galvanized air ducts are used, while stainless steel pipes are very suitable for galvanized spiral air ducts in corrosive and particularly humid places. Generally, galvanized air ducts are used, while stainless steel pipes are used in corrosive and particularly humid places.

People buy in daily life production Acetylene tape 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. Acetylene tape 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.

Baoji Acetylene tape Also called pu steel wire pipe, ventilation pipe, dust removal pipe, dust collection pipe, dust conveying pipe, industrial powder dust collection pipe, sweeping car dust collection pipe, drilling machine dust collection pipe, woodworking dust collection pipe, collectively called dust collection pipe. Therefore, industrial food dust transportation and industrial dust transportation are used for dust collection pipe. The production process structure of copper plated steel wire dust collection pipe is to wrap the pipe wall with solid elastic copper plated steel wire spirally, and the pipe wall material is coated with copper plated steel wire with special polyether PUR. PUR material is also called PU material. The thickness of pipe wall can be 0.4mm, 0.6mm, 0.9mm, 1.2mm, 1.5mm, 1.8mm and 2.1mm, depending on the customer's needs. Such as the temperature, wear resistance, flexibility and bending, hydrolysis resistance of the dust collection pipe. It is also necessary to consider whether static electricity is generated in the process of pipe full conveying dust to avoid unnecessary dust explosion and fire. Copper plated steel wire plastic coated dust collection tube is suitable for vacuum suction of powder and particle in industrial and mining, agriculture and water conservancy, civil engineering, food, petroleum, chemical industry, health and other industries, as well as transportation of water, oil, chemical materials, food, etc. Abrasive solids such as dust, powder, fiber, chip and particle, gas and liquid environment, for dedusting and suction plant, Acetylene tape Price Industrial vacuum cleaners, paper and textile fibers, are used as protective tubes. It is widely used in farmland irrigation, industry and mining, oil depot, sand extraction, sand blasting, food, medicine, indoor gas, powder, dust absorption and emission and other fields. This product is a substitute for PVC, rubber and metal pipes.

Let's take a look today Baoji Acetylene tape 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 Baoji Acetylene tape 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.
