Granite is a kind of man-made stone product. It is a kind of green and environmental protection building material, which is made of natural marble, shell, glass, mosaic, etc. with high-quality polymer as binder and refined by advanced manufacturing technology.
Due to the precise selection of the technology, the radioactive materials contained in the stone are almost completely eliminated. In addition, the high-performance adhesive after high-pressure bonding makes its tenor greatly increased, and some of its strength is even higher than that of natural stone. In the synthesis process, the centralized batching process is used to completely solve the color difference problem in the natural stone decoration process, which is especially suitable for large area pavement in engineering. In the processing process of natural marble, due to the limitation of stone itself, customers can only process with the size of the plate, but not with their own design. However, the size of granite plate is large, with 3050 × 1250 × 12mm ultra-thin large plate, which can not be compared with natural stone.
The production process is as follows: ore → crushing into different particle size crushed stone → adding special raw material formula of granite → mixing and mixing → distributing → forming square material after forming in vacuum high village → diamond row saw → rough board → scraping and sizing → fine grinding and polishing → longitudinal and horizontal cutting machine → finished product.
Artificial granite plate production base, the following is the vacuum pump use site.
Pump selection principle
When designing equipment, the design institute should determine the use and performance parameters of the pump and select the pump type. This kind of choice must start from the choice of pump type and form, then what principle to choose pump? What is the basis?
1. Make the type and performance of the selected pump meet the requirements of process parameters such as flow, head, pressure, temperature, NPSH, suction head, etc;
2. It must meet the requirements of medium characteristics. For pumps conveying flammable, explosive, toxic or valuable media, the shaft seal shall be reliable or non leakage pump shall be adopted, such as magnetic drive pump (without shaft seal, isolated magnetic indirect drive). For pump conveying corrosive medium, corrosion-resistant materials shall be used for convection parts, such as fluoroplastic anti-corrosion pump, and for pump conveying solid particle medium The convection parts shall be made of wear-resistant materials, and the shaft seal shall be washed with clean liquid if necessary;
3. Mechanical requirements require high reliability, low noise and small vibration.
4. See how to calculate the cost of the purchase pump correctly. 4, correctly calculate the input cost of pump purchase.
