Insert the moving piece into the transmission sleeve, fix the transmission sleeve on the anti-rotation pin of the sleeve, and evenly tighten the sealing gland screw to check the mechanical seal that is assembled according to the above assembly process, and push the ring to the spring seat. Anti-rotation slide reported 17 and rotated 1530, pressing the spring, so that the mechanical seal compensation mechanical elastic force does not have axial compensation ability, the seal end face wear 6 no light forms a good fit, resulting in mechanical seal leakage 3 improved after type 104 Mechanical seal assembly process and precautions The quality of the mechanical seal, the shaft diameter of the pump, the manufacturing precision and the sealing chamber are strictly checked during assembly. 3.2 On the pump shaft of the pump body seal cavity, the strip line is accurately drawn and the static is measured. The distance from the end of the ring to the end face of the seal determines the mounting position of the spring seat on the shaft. 3.3 Based on the reference line drawn by the pump shaft, the mounting position of the spring seat at the end of the sleeve is marked on the sleeve, and the static ring and the installed static ring are installed. The static sealing ring is inserted into the sealing gland, and is clamped in the anti-rotation groove of the gland, and is mounted on the shaft 14 to insert the spring into the spring seat, and the push ring moving ring and the sealing ring are sequentially loaded into the elastic scorpion to make the push ring , the moving ring anti-rotation groove is embedded in the spring seat In the transfer chute, the transmission piece of the spring seat is inserted into the rotating sleeve, the transmission sleeve is fixed on the anti-rotation pin of the sleeve, the pump body is mounted, and the sealing gland 15 is tightened during the installation process, and the push ring can not be moved to the spring seat The anti-rotation slide presses the rotation to catch the spring, so that the compensation mechanism loses the compensation energy. After the seal end face wears, the elastic compensation mechanism can automatically adjust the axial displacement to ensure that the seal end face is always kept close to the leak, and the leakage is eliminated. Extended service life.
4 After the improvement of the process, the use of mechanical seals is compared with the above process to extend the service life of the mechanical seals. It is said that the machine can seal the maximum number of mouths for 45 days, and after 163 days of continuous use after the new process, we will make a number of before and after assembly. Comparison of the amount of wear and tear before and after the installation, the number of comparisons on the development and application of thermal insulation materials. Yan Wanming Jiang Yiqun Inner Mongolia Petrochemical Research Institute City Coal Gasification Corporation summary of new insulation deep temperature materials, the brief situation, the author The production management and product management, as well as the participation in other research and development work, personal experience and experience, set theoretical knowledge and applicability in this book, put forward, understanding the design, production and marketing of new products, In order to transform the productivity of scientific and technological achievements as soon as possible, and finally form industrialized scale production and marketing, it puts forward the important reality of the development of human society, which can be deeply thought and necessary to progress. It can be said that it is made with human beings. The development and application of building materials related to the development of primitive society for the sake of the earth, Natural cockroaches began with the use of natural burrowing. With the gradual increase of population and the increasing productivity of water rafts, humans have learned to build houses by using natural materials such as grass, skin and sand, and gradually improve the survival of human beings. The environment, this is the progress of the society, the development of material civilization, people's understanding of the objective world things, the understanding of the nature and regularity, the continuous expansion of human activities, the frequent exchanges of people around the world, this is the people In the pursuit of the improvement of living conditions and the desire to improve the quality of life, the flower has become a reality. So far, people have widely used brick, sand, cement, concrete, and concrete members to build various types of buildings. Over the years, the large amount of research, development, production and application of various new building materials has become a new feature of the development of building materials industry in the future. The production and application of thermal insulation materials with excellent performance is an important component of new building materials. It has been proposed that in 2000, the total production of new wall materials in the country will reach 2, including Beijing. dog. Tianzhu and other 23 large and medium-sized cities across the country have determined that the production of new wall materials in 2000 should reach 40 50. In the future, the production of thermal insulation materials, which are important components of traditional building materials, will be replaced by new interest. In a broad sense, the various building materials used in the past have a certain thermal insulation performance. It has made due contributions to the development of human society. With the development of science and technology, people are not satisfied. Only to improve the living conditions, but to continuously improve the production conditions to pre-install the f after the static ring 19.2 boss 3.3 the static ring height 18.94 boss plus the inner diameter of 56 continent outer diameter 74.7, the inner diameter of 56 continents 74.6 The height of the ring is 15.3, the height of the boss is 1.4, the inner diameter of the book is 55.86, the outer diameter is 74.5, the inner diameter is 55.86, the outer diameter of the book is 74.5, and the spring height is 46. The height of the spring is 46. The diameter of the sun is 69. If the inner diameter is 60, the outer diameter is 69. If the assembly process is correct.
5 pairs of 104 type mechanical seal installation to improve, eliminate the leakage of equipment, improve the efficiency of the pump, improve the working environment of the operator, play a safe and stable operation, energy saving mechanical seal, and is not continuous operation of. From January 1998 to the beginning of September, 98, a total of 462.78 yuan was calculated, which saved 5,000 yuan in this year. The economic benefits are considerable. After using the new installation process, the machine has been replaced by the machine. Sealing from the above data analysis, the static and dynamic ring seal end face wear is not large, the body spring is not deformed, the body ring is worn, so that it can be judged that the mechanical seal can still be used for more than 200 days, which proves our
