On large-scale management of road-building machinery and equipment installation and debugging

Large road-building machinery and equipment management is a very complex process, it is not only bulky, ancillary units and ancillary equipment and technology, installation is more complex. As a unit, the person concerned must be made (mechanical technicians, machine operators, engineers and technicians) to understand its management procedures and methods of installation, so that human right organizations, effective use of resources, successfully completed large road-building machinery and equipment installation and commissioning work.

1. installation and commissioning costs budget

To make the large road-building machinery and equipment installation and commissioning work execution and completion of required to do installation and commissioning costs. Installation costs include transportation, installation, commissioning fees, other costs, and so on.

1.1 transport budget

Maintenance Department according to the large road-building machinery and equipment volume, shipment quantity and quality of the object the dissolution, arrange different transport capacity of vehicles and identification of train transport vehicles. Then, press the corresponding transport vehicle kms of freight, goods transport mileage calculation of shipping costs. Class costs can also transport vehicles fixed and use class number may calculate the freight charges. When the transport expenses in the budget, and to estimate the loading and unloading, strapping, etc. Which is the inevitable expenses incurred during transport.

1.2 installation costs

According to install large road-building appropriate to the type of machinery installed base, feeding station used masonry materials (such as wood, iron, wire, cement, bricks, sand, stones etc) and lifting equipment, small machines and artificial (technicians and general workers) use, and follow the highway project budget quota's base price, calculate their costs.

1.3 debugging costs

In the process of debugging large road-building machinery and equipment, in addition to the required fuel equipment operation (such as fuel, electricity, water, gas, etc), needs a certain amount of engineering materials for their processing (such as gravel, asphalt or concrete, sand or gravel, lime and fly ash). Using imported equipment for the first time, you must after a certain period of no load, load and continuous, ongoing evaluation and, therefore, should be noted enough of engineering materials. Commissioning fee usually consists of fuel or electricity fees, engineering materials, auxiliary machinery, labor fees, management fees and so on. Every fee should be in their own price and quantity to calculate. In addition to required auxiliary machinery, consumable materials, and related personnel management.

1.4 other costs including equipment to care fees, management fees, and so on. Other costs budget should be carried out according to the actual situation.

2. the staff organization and technical training

Sophisticated and expensive large road-building machinery and equipment, and technology in the initial installation and commissioning must be performed by suppliers to send technical staff (which is also a supplier must fulfil the obligations to complete delivery). Purchase units in the supplier before the commissioning engineer, work as well as possible. Such as matching operators, installation and commissioning coordination group was established (by the

Close the administrative leadership, technical personnel), the deployment of installation and commissioning of the necessary auxiliary equipment, personnel (enclosed fitters, electricians, machinists, etc). When matching operators, should pay attention to selecting skilled mechanical knowledge, responsive, responsible operators, widely used for electrical, hydraulic, mechanical, and computer equipment for road-building machinery, suitable for matching with secondary education, ambition and technical personnel to serve as captain. Prior to the installation and commissioning, technical director of acquisition unit should help the manufacturers installation and commissioning engineers work, and the matching of job distribution and on-site technical training for equipment operators. Job distribution designed explicitly for the operator during the commissioning phase and the future users of the facility's responsibility. The purpose of the training is to let the operator know transfer equipment construction, performance, installation and commissioning procedures, operation management method, and security considerations, and so on, so as to make them aware, avoid blind on the machine.

3. install

Large road construction machinery and equipment (shipment status before installation is usually the solutions) installed include: getting ready for an installed base of construction, installation, equipment installation processes.

Installation 3.1 base construction

Construction on the base line, equipment installation location must be determined reasonable and rational distribution of support machinery and transport vehicles and feeding stations, Stockyards and, if necessary, trimmed. More for the large road-building machinery and equipment Assembly, in order to successfully assemble and maintain stable performance after installation, in the measurement line, precast or masonry base early, shall be carried out strictly according to the technical specifications and construction.

3.2 installation preparation before

Equipment installation and appearance quality check it again before. Such as no loose bolts, nuts welded welds have no cracks, holes and other defects; fuel lubricant oil and gas reserves and pipe fittings are solid, leak-free; circuit wiring is tidy, insulation performance; safety and security of all parts of the reciprocating motion of rotating parts of the effective and complete level, and so on. In addition, to further review the setup required for small machines, material readiness.

3.3 installation

The installation process should be kept on the device host the Assembly parts and ancillary equipment to do quality checks. The installation site must be delivered by hand in command. Aerial installation or when lifting heavy equipment, appropriate safety precautions must be taken. Installer you want to all wearing hard hats. Installation work to be carried out in order. Otherwise, not only difficult to place, connected to each other and hoisting equipment

Cannot display. Install to Division of labor and cooperation, such as: mechanical parts by mechanical personnel responsible for the installation and electrical connection of the electrical officer. After installation, the rationality of the integrity of the installation, safety checks.

4. debugging

Large road-building machinery and equipment in the factory generally unable to load Assembly and test, even if the equipment is used, once again, due to the demolition, removal and installation, will inevitably alter the original installation state, so the debugging of large road-building machinery and equipment installed as soon as possible is very important. Should recognize that, not only is the disintegration of the shipment of large road construction equipment used for the first time after installation you want to debug, in fact, all new, updated, homemade, transformation, (middle), machinery and equipment, before using, you must debug. Debugging, to once again check the Assembly of the integrity, legitimacy, security and signs of leakage and so on, to try security and the smooth implementation of apoptosis. When you are debugging, mainly tests the quality of their work, performance, reliability, economy and so on. Review, no-load and load test should be at the construction site to correctly test the performance of industrialized production technical requirements are met. In the debugging process, mechanical technician, and participating in the debugging random operators need to keep in place to actively understand the reality of equipment, commissioning procedures, control methods and so on. Field must have mechanical technicians record the debugging process. Because it is the original record would be future equipment operation, writing technical reports, an important basis for resolving the remaining issues.

5. write installation technical reports

Written installation and commissioning of a technical report is a large road-building machinery and equipment after the initial installation and commissioning technology, asset and financial acceptance as one of the main bases, was a must do a good job. Installation and commissioning report readers should be able to reproduce the installation process, and results in accordance with article shall prevail. Large road-building machinery and equipment installation and debugging of a technical report as a document, its content is deep, concrete, the persons concerned should be aware of its importance. Differences between written notice and papers should be proper detail, prioritize, not as good as running account, what month and year did a debug all written reports, one to no avail. At the end of installation and commissioning of a technical report. Would like to have the installation work to help, support or guide thanks to the people and departments. This practice is actually stated in the course of installation, commissioning departments and personnel work, a method of work or achievement.

6. technical inspection

Large road-building machinery and equipment installation and debugging symbol of success are: equipment installation completed examinations, indicators of economic and technical performance in line with the order stipulated in the contract, with industrial production. After the end of the large road-building machinery and equipment installation and commissioning to technology acceptance and summarized. After the technical reports, equipment installation and debugging files, review of documents, data and field survey before deciding whether through technical inspection. Technology acceptance, will be allowed to handle the assets, financial procedures, delivery. Without technical acceptance shall not be accounted for and put to use, or it will cause unclear responsibilities. For a large road-building equipment installation, debugging errors in the process, to summarize. Responsibility for the existing problems to distinguish and deal with matters relating to claims, must be resolved properly within the validity period.
