Xining Oil resistant hose 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 Oil resistant hose company 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.

Comprehensive evaluation of world conveyor belt wear-resisting Oil resistant hose The development level and the application practice of large industrial and mining enterprises in China, in the future, the technology and market development of conveyor belt vulcanizers in China will show the following eight characteristics: more intelligent: Canada Xiaoai Group has recently launched a new X-PAD conveyor belt vulcanizer control system, which uses full touch color screen control, and one operating system can implement real-time monitoring on multiple pairs of vulcanizer heating plates, And it can conduct remote monitoring through WIFI. This system will greatly improve the intelligent control degree of conveyor belt vulcanizer, and undoubtedly represents an important trend in the future development of conveyor belt vulcanizer technology. Higher cost performance: With the improvement of refined management of industrial and mining enterprises, the extensive "stupid and bulky" equipment can no longer adapt to modern production, and the provision of "customized combination" system solutions will become an inevitable choice for future conveyor belt vulcanizer suppliers - conveyor belt vulcanizer is a "tool type" equipment, Suppliers or design units can assist industrial and mining enterprises to comprehensively analyze the belt width, lap length and other use conditions of the conveyor system, and customize the overall solution of the conveyor belt vulcanizer that can be applied to multiple belt joints and maintenance at the same time. So as to effectively reduce procurement costs. More security: in terms of security measures, Oil resistant hose company As the leader in the conveyor belt vulcanizing machine industry, Xiao Ai segmented vulcanizing machine can be used as a model: (1) its beam system adopts aviation grade aluminum profile, zhuanliE design, and has a safety window. When it is used, it penetrates the safety bar, and is equipped with a safety pin protection system; (2) International certified cables such as American UL are used to fully ensure the safety and reliability of use. (3) The recently launched new UBR vulcanizing machine pioneered the use of new materials to replace the bolt structure with a strong rope system, and designed a related structure between the new beams, which used the safety protection measures of the vulcanizing machine pressurization system to the extreme.

The spiral air duct will certainly be affected in the low temperature environment, so how should our manufacturer deal with this situation? First Oil resistant hose company Do a good job in thermal insulation and select thermal insulation materials (applicable to industry and construction industry), but the selection of thermal insulation materials (applicable to industry and construction industry) is also necessary. Shandong Hongyuansheng, a spiral air duct manufacturer, will tell you how to choose. Good thermal insulation performance. The specification of the next thermal insulation material (applicable to industry and buildings) should meet the requirements of the air duct system used, not only that, but also the design requirements of the air duct. The thermal insulation material (applicable to industry and buildings) has product quality certificates and other qualified documents. Galvanized spiral air duct is widely circulated in the municipal spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Composite spiral air duct is generally used in the environment where the environment is common, and the requirements for air duct are not too high. Thermal insulation materials (used in industry and construction) can effectively protect pipelines from damage in winter. Galvanized spiral air duct is widely circulated in the spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Xining Oil resistant hose It is generally used in the environment where the environment is common, and the requirements for air ducts are not too high. In terms of clean air ducts, fire-resistant closed cell rubber foam insulation materials (used in industry and buildings) are generally used, and incombustible aluminum (aluminum) foil glass wool board is used for smoke exhaust ducts. These two materials are common and have good thermal insulation performance.

I, wear-resisting Oil resistant hose Quantitative display of quality. In the evaluation plan prepared by the Ministry of Health and Social Insurance for the medical and health system, some indicators were put forward for the service quality of the hospital, such as the number of deaths before and after the operation, the number of unplanned rehospitalization, the infection rate of patients in the hospital, and the immunization rate. It can be seen that the quantification of quality is to reflect the quality of things through a series of quantitative analysis and synthesis. Sand blasting hose enterprises use public opinion polls to measure benefits and service quality. Since the purpose of administrative activities is to meet the needs of society or the public, the best way to measure the social effect and quality is to face the service objects, understand their evaluation and their satisfaction. Although popular, public opinion polls also have limitations, such as high cost, which is difficult to be accurate and reliable due to the influence of public judgment. In addition, the satisfaction of beneficiaries does not answer the question - is this service provided to those who need it most? III, Oil resistant hose company Administrative departments and public service institutions with single business nature. For those departments that have applied the quality assurance system, their performance evaluation only pays attention to efficiency and economy.

wear-resisting Oil resistant hose The manufacturing of is highly automated and the production speed is very fast. The general air duct can produce 20~40 meters per minute. Due to the low price of its raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost of spiral air duct is lower than that of rectangular air duct; In addition, the total cost of spiral air duct is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air ducts are prone to turbulence, reducing the effective flow area, the spiral air ducts have good air fluidity and large effective flow area, so the secondary noise of spiral air ducts is low. Because the spiral air ducts are strong, the low-frequency noise caused by air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power. Spiral air ducts in the market are generally divided into three categories according to their materials: galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Among them, spiral air duct has the best quality and strong applicability, but its price is high. At present, the most widely circulated spiral air duct on the market is galvanized sheet. The galvanized sheet spiral air duct is basically the characteristic of stainless steel spiral air duct, but its price is only two thirds or even lower than that of spiral air duct. Xining Oil resistant hose It is generally used in places where the external environment is relatively common and the requirements for air ducts are not too high. As the iron sheet is prone to chemical reaction in various environments, corrosion and rust will occur. However, zinc hardly changes in dry air. In humid air, dense basic zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating with light protecting agent.
