Installation and use of mechanical seal requirements 1. Must be according to the working condition and a host of suitable type of mechanical seal and material matching, to ensure the normal working of the machine seal and service life. 2. Installation of mechanical seal parts of the shaft ( Collar) The radial runout tolerance should be 0 or less. 4 mm, rotor axial momentum 0 or less. 1mm。 3. Installation of mechanical seal stationary ring sealing end cover ( Or shell) , positioning in the face of axis perpendicularity 0 or less. 04mm。 4. Mechanical seal when installation, must be axis ( Collar) End cover, seal cavity, seal and mechanical seal itself clean, prevent any impurities into the sealing parts. 5. When the temperature of the medium to high, low, or containing impurity particles, inflammable, explosive, toxic, must refer to relevant standards, mechanical seal to take corresponding resistance, irrigation, cooling, screening and other measures. 6. The mechanical seal installation, proper lubrication. According to the product installation instructions, to ensure that the mechanical seal installation size. 7. Equipment must be full of medium before operation, to prevent dry friction and make the seal failure. 8. Sample of single spring mechanical seal, should be spring to reasonable choice, generally, when looking from the stationary ring clockwise for axle steering, choose the right spring. Choose the left spring conversely.

Mechanical seal elastic component material
　2019-03-13　　
Material of mechanical seal elastic element:
The elastic components of the mechanical seal include springs and bellows. Both are spring-loaded components, whose function is to ensure a good combination of dynamic and static rings, pre-compression and automatic compensation when the end surface is worn or fluctuates. The requirements for elastic materials are: corrosion resistance in the medium, and do not reduce or lose the original elasticity under long-term working conditions. After the mechanical sealing surface is worn, the necessary pressing force can be maintained, that is, the reduction rate is no more than 10%-25% of the original spring force.

Analysis of my country's sealing machinery industry my country is the country with the fastest increase in the production of sealing machine equipment. Following the changes in shopping malls, domestic sealing machinery is also growing. Although there are few domestic sealing machinery manufacturers that can conduct professional research and development, the sealing machinery has also achieved good results with continuous efforts, especially the high-speed, complete set, high degree of automation and high reliability of beer and beverage filling equipment. With the development of global science and technology, developed countries have integrated nuclear energy technology, microelectronic technology, laser technology, biological technology and system engineering into traditional mechanical manufacturing technology. New alloy materials, polymer materials, composite materials, inorganic non-metal materials and other new materials have also been promoted and applied. The integration, intelligence, networking, and flexibility of food sealing packaging machinery will become the mainstream of future development. The sealing machinery industry faces the needs of the market and how to catch up with or even surpass the food sealing machinery of developed countries with mechanical seals for kettles, and how to increase the pace of self-innovation, and strive to announce a batch of independent intellectual property rights and international advanced in a short time. The level of commodities is an urgent need for food sealing machinery companies in our country. The sealing machine refers to the machine that seals the container after the packaging container is filled with goods. There are many materials for manufacturing packaging containers, such as paper, plastic, glass, ceramic, metal, composite materials, etc., and the shapes and physical functions of packaging containers are also different. Therefore, the sealing methods and sealing equipment selected are also different. (1) Flexible container sealing equipment: Flexible containers are bag-like containers made of flexible materials, such as paper, plastic film, and composite film. The sealing of this type of container is mostly combined with bag making and filling, and it is rarely used independently, because the materials are different and the sealing equipment is also different. ①Paper bag sealing equipment. Regarding paper materials, adhesives are usually applied to the seal and then sealed with mechanical pressure. ②Sealing equipment for plastic film bags and composite film bags. Many plastics have outstanding heat-sealability. Plastic bags or composite bags made of this type of plastic are usually directly heated at the seal and applied mechanical pressure to fuse and seal. (2) Rigid container sealing machine: a rigid container refers to a container whose shape is not easy to change after the container is formed, and its sealing is mostly with a different way of lid. The commonly used sealing machines are as follows. ① Capping and sealing machine. This kind of cover has internal threads processed in advance, and the threads can be single-ended or multi-threaded. For example, single-threaded threads are often used for medicine bottles, and multiple-threaded threads are used for canned bottles. This machine relies on rotating the cap to compress it to the mouth of the container. ②Knurling sealing machine. This kind of closure is mostly made of aluminum, and there is no thread beforehand. The aluminum cover is rolled with a roller to make it appear exactly the same as the thread shape of the bottle mouth, and the container is sealed. This kind of cover breaks the indentation along the periphery of the skirt when it is unsealed, and cannot be restored, so it is also called 'anti-theft cover'. This machine is mostly used for the sealing and packaging of high-end wines and beverages. ③ Hemming sealing machine. It first puts the cylindrical metal cap on the bottle mouth, rolls the bottom edge with a roller to make it inverted and deformed, and tightly buckles the flange of the bottle mouth to seal it. This machine is mostly used for sealing and packaging wide-mouth cans and bottles. ④ Gland sealing machine. It is a crown cap sealing machine specially used for beer, soda and other beverages. Place the crown cap on the bottle mouth, press the press mold of the machine, the corrugated periphery of the crown cap is squeezed and contracted, and it is stuck on the flange of the neck of the bottle mouth, forming a mechanical hook connection between the bottle cap and the bottle mouth. Thus, the bottle is sealed. ⑤Press plug sealing machine. This kind of sealing material is a bottle stopper made of rubber, plastic, cork and other materials with certain elasticity, and uses its own elastic deformation to seal the bottle mouth. When the machine is sealing, the bottle stopper is placed above the bottle mouth, and the vertical pressure on the bottle stopper is pressed into the bottle mouth to complete the sealing and packaging. The cork seal can be used as a stand-alone seal or as a combined seal together with the bottle cap. ⑥Crimping and sealing machine. The machine is mainly used for sealing metal food cans. It uses rollers to complete the hermetic packaging by bending, hooking and pressing the periphery of the can cover and the can body flange. Packaging machinery has been developed for decades, and packaging machinery has gradually developed to the present multi-category, multi-functional packaging machine, filling machine, shrinking machine, sealing machine, packing machine, coding machine and other products, while the sealing machine It is precisely in accordance with the needs of packaging and sealing in the society to do our best to research and develop new sealing equipment.
