Improper installation and adjustment of the worm wheel in the steam turbine reducer will cause malfunction in all aspects. If the main oil pump is damaged and cannot be supplied with oil, the governor will be shaken, the tachometer indication will be inaccurate, etc., and eventually the unit will be unable to operate. The malfunction of the worm wheel set is manifested in improper connection of the teeth or poor contact. The incorrect connection of the teeth is mostly due to the large difference between the actual center distance of the worm wheel set and the design number. However, the actual center size gap is too large or the center line is not perpendicular to the manufacturer, and there are also improper installation and adjustment of the site.
When the steam turbine is running, the center line of the worm should be located in the central plane of the worm gear teeth. When the turbine is stopped, the coloring check worm wheel can be correctly placed at this position.
In the coloring inspection, the working face of the worm gear should have more than 57 contact areas and be uniform. If the contact area is insufficient or the one side is colored, it means that the position of the worm wheel is to be adjusted. A good check of the coloring check worm wheel set does not fully explain the suit of the worm wheel. Because when the turbine is running, some movement of its shaft will occur, and the positional relationship between the worm and the worm wheel will change.
In order to mount the worm gear on the horizontal axis as much as possible in the correct position during operation, the following important conditions must be met: when the turbine rotor rotates clockwise (as viewed in the direction of the steam flow), the working surface of the worm wheel teeth There are colors from 1/2 to 3/4 on the right side. To do this, the worm wheel must be moved slightly to the left (change the thickness of the adjustable gasket).
Heat Transfer Machine
Heat transfer machine is a heat transfer technology used in the general term of the machine, heat transfer machine, including flat heat press machine, high pressure heat press machine, shaking his head heat press machine, baking cup machine, baking machine, baking machine and other thermal transfer machine. Can print a wide range of both flat heat transfer, including cups, plates, hats, these surface heat transfer, thermal transfer is a new technology, just just on the right track.
Features of heat transfer process
- Picture exquisite, with ordinary hot stamping machine, heat transfer machine to complete.
- Ke-color pattern of a molding, without chromatography.
- Simple operation, fine workmanship, low production costs.
- Product loss is small, high added value, process decorative strong.
- High hiding power, strong adhesion.
- In line with the green printing standards, no environmental pollution.
Advantage
1. The steps are simple
It does not need to plate, copy, repeat the chromatography step, without the need for screen printing and thermal transfer methods required for various types of tools, materials. With a universal printer, you only need to prepare a separate computer. A computer operator can be completely independent of the printing operation, the province of human and material resources, and the way is simple, Lidengkequ, the operator of the experience of low requirements, as long as the understanding of a simple picture processing software on it.2. To avoid damage
It can be printed not only on the tough crystal, stone, metal, glass and other materials, but also can be printed on the soft texture of leather, cloth, cotton and other materials; it can be printed on the inorganic, can also be printed on the composition of complex , Change the organic matter on. On the material with more and better compatibility, the use of spring-hui of the number of straight-jet printing machine to avoid the screen printing, water transfer printing material selection issues, but also to avoid the thermal transfer of leather, fabrics, cotton and other organic materials Destruction of the problem. It caters to the diversified needs of the market, to better provide users with more comprehensive production services.3. Avoid skewing
Universal printer is no longer in the traditional printing mode and method is no longer a simple manual operation and technology printing, and computer technology and high content of computer synthesis and automatic control technology for a better organic combination can be very precise alignment Need to print the area and location, to avoid the manual printing encountered by the position of the problem. Because it is a one-time multi-color printing, there will be no problem of chromatic alignment. These advantages can also be engraving, etching very effective combination in the engraving of the region to print a beautiful picture, or after printing accurate etching, etc., in the carving industry can achieve a good breakthrough.
