Machinery and equipment to install the main work of the process

Machinery and equipment to install the main work of the main content:
1. Equipment out of the box inspection
Before the installation of the equipment, the construction party shall be responsible for checking, registering and inspecting the installed machinery with the owner (or its representative) and / or the supplier in accordance with the equipment packing list and the equipment technical documents. Parts need to be checked by quality standards for acceptance, inspection should be formed after the test records.
2. Base line (buried center plate and reference point)
According to the equipment layout and measurement control network to determine the equipment installation of the baseline and the reference point. The flat position and elevation of all equipment installations shall be measured on the basis of a defined baseline and reference point. Vertical and horizontal centerline of the production line and the center line of the main equipment should be buried permanent center line standard plate, the main equipment should be buried next to the permanent elevation reference point, so that the installation and production after the maintenance of a reliable basis.


4. Horn set
By adjusting the thickness of the horn, the equipment can be installed to meet the design requirements of the level and elevation, and the weight of the device through the horn evenly transmitted to the foundation to increase the stability of the equipment. The horn set should meet the following requirements:
(1) The contact between the horn and the equipment base is good.
(2) There should be at least one set of horns next to each anchor bolt and placed near the anchor bolts and the main force at the base.
(3) Equipment base on both sides of the seams, should be placed a set of horns.
(4) the distance between adjacent two horns, preferably 500 to 1000 mm.
(5) the number of blocks per horn group should not exceed 5, placed flat horn, the thick should be placed below, thin should be placed in the middle, the thickness of the horn should not be less than 2mm.
(6) Every horn group should be neat and smooth. Good contact. After the equipment is flattened, each set of horns should be pressed.
(7) equipment leveling, the end of the horn should be exposed to the bottom edge of the equipment; flat pad iron should be exposed 10 ~ 30mm; oblique horn should be exposed 10 ~ 50mm. The length of the horn into the bottom of the equipment base should exceed the center of the equipment anchor bolts.
(8) except cast iron horn. After the equipment is adjusted, the horn is applied to each other.
5. Equipment hoisting in place
Large equipment hoisting in place should be prepared special construction program. According to the characteristics of the installation equipment, lifting the operating environment conditions and the use of lifting transport machinery, select a safe and reliable, economically viable lifting program, and in accordance with the hoisting transport program configuration of the corresponding machinery, tools and personnel. Hold the device in place
6. Installation accuracy adjustment and detection
(1) precision adjustment and testing is a mechanical equipment installation project in a key link, a direct impact on the installation of equipment quality.
(2) Accuracy adjustment The equipment itself and the mutual position status shall be adjusted according to the technical requirements of the equipment installation (as specified in the specification or equipment technical documentation) and the accuracy test results. For example, the center position, level, verticality, parallelism, etc. of the equipment The
(3) precision detection is the detection device, the relative position between the components of the error, such as vertical, parallelism, coaxial.
(4) All position accuracy and partial shape accuracy items, involving error analysis, dimension chain principle and precision measurement technology.
7. Equipment is fixed and grouting
(1) In addition to a small number of mobile machinery and equipment, most of the mechanical equipment must be firmly fixed on the basis of equipment, especially for heavy, high speed, vibration of large mechanical equipment, if not fixed firmly, may lead to major accidents.
(2) For the disassembly equipment should be fixed in place before the base, and then the upper part of the installation and assembly of equipment.
(3) equipment grouting is divided into a grouting and secondary grouting.
A grouting is in the equipment after the rough finding, the anchor hole on the anchor pipe;
Secondary grouting is the grouting of the equipment base and the foundation after the equipment is well positioned.
8. Parts assembly
Disassembly, cleaning and assembly shall be carried out for the disassembled machinery and the overall mechanical equipment exceeding the shelf life of rust.
9. Lubrication and equipment refueling
This is necessary to ensure the normal operation of machinery and equipment. Lubricating oil and lubricating parts to be clean; lubricant selection is reasonable, the quality to meet the requirements; equipment and lubricants to join the amount of oil should be appropriate.
10. Equipment test run
This is a comprehensive test equipment manufacturing and equipment installation quality of the important links, involving more professional, more staff, to be carefully organized, unified command.
11. Engineering acceptance
Equipment test run qualified, should be timely for engineering acceptance.
