One, the arrival of equipment to prepare for 1. equipment arrives to understand the weight of a single piece of equipment, the use of matching lifting weight shall not be greater than the maximum load capacity of the traveling crane, not blind, barbaric lifting; 2. equipment should be placed in a neat and orderly manner, packages cleaned up in a timely manner, to keep the installation site clean and tidy; 3. the surface of the foundation of the equipment and the water, electricity, gas pipe lining should be cleaned of oil, dirt, sand, debris, water and so on. Pipe oil, sand, gravel, water, etc. should be cleaned up, lining the interceptor height should be slightly higher than the ground; 4. pre-buried water, electricity, gas piping should not be higher than the ground, the installation should be carried out before the pressure test, to prevent leakage of the pipeline; 5. equipment in place, according to the construction drawings and the relevant building's axial or edge line and elevation line, delineation of the baseline for the installation; 6. equipment installation, there are hidden dangers of the location should be Place warning signs. (such as pits, overhanging equipment, higher and not fixed base equipment, etc.); Second, mechanical equipment installation standards 1. pre-buried foot bolt threads and nuts should be guaranteed intact, there shall be no bruising, bending and other phenomena; 2. foot bolts should be cleaned of oil and oxidation, the threads should be coated with a small amount of grease; 3. equipment positioning is completed, the ground nut needs to be fastened in place, the bolt should be exposed to the nut of the length of 1/3 or 2/3 of the diameter of the bolt or the length of the bolt. The length of the bolt exposed to the nut should be 1/3 or 2/3 of the diameter of the bolt; 4. The contact between the nut and the gasket, the gasket and the base of the equipment should be even and tight; 5. The equipment should be leveled with inclined washers, adjustment washers or flat washers. There should be at least one set of washers next to each ground bolt. Matting iron should be placed close to the foot and the base of the main stress parts of the bottom, the distance between adjacent sets of matting iron should be maintained within 500 --- 1000mm; 6. bear the load of the matting iron group, should be used in pairs of sloping matting iron, and leveling should be welded firmly before grouting; 7. bear heavy loads or strong continuous vibration of the equipment should be used flat matting iron, use should not be used in the use of thin matting iron and should not be more than 5, thick matting iron should be placed on the bottom, and the thick matting iron should be placed on the bottom, the bottom, the bottom, the bottom, the bottom, and the bottom should be placed on the bottom. Thick pads should be placed in the bottom layer, thin placed in the middle and the thickness should not be less than 2mm, and should be firmly welded pads, cast iron pads can not be welded; 8. Each group of pads should be placed neatly and smoothly and good contact. After the equipment leveling, each group of pad iron should be pressed, and should be hand-hammered group by group to listen to the sound check. For high-speed operation of the equipment should be 0.05mm ruler to check the gap between the pad iron and pad iron and equipment between the base, in the pad iron at the same end, both sides of the total length of the plug into the ruler shall not exceed the total length or width of the pad iron 1 / 3; 9. equipment leveling, pad iron end should be exposed to the edge of the base of the equipment, the flat pad iron is suitable to expose 10 --- 20mm, inclined pad iron is suitable to expose 10 --- 40mm. The length of the pad iron group into the equipment base should exceed the center of the equipment foot bolt. Installation in the metal structure of the equipment leveling, the pad iron should be welded firmly; 10. All need to field assembly of the equipment should be carefully installed, with precision. All bolts and locating pins should be installed in place and fastened, and should not be omitted or under-installed; 11. According to the maximum amount of water and gas intake and discharge of the equipment, select the appropriate size of the pipe. Equipment that can be operated independently should be reserved for separate control of the valve;
