Mechanical equipment installation

1. preparation stage

The Preparation work includes supply preparation, technical preparation and organizational preparation. Quality control during the preparation phase can effectively guarantee the quality of Mechanical equipment installation. Quality control at this stage has the following points: First, a rigorous inspection of the quality of the required materials and equipment, including whether the equipment parts are complete, whether the equipment is worn, whether it is qualified, and whether the materials and equipment specifications meet the design requirements Wait. Second, the installation and construction personnel should check the equipment foundation's geometric dimensions, coordinate positions, concrete mix ratio, and strength according to the equipment drawings. After the inspection is qualified, the supervision engineer confirms the signature. Third, the basic elevation and pre-embedded equipment are checked and accepted, and on-site embedded parts, centerline elevations and cleaning work are carried out in accordance with construction requirements.

1.2 Installation stage

The In place: Mechanical equipment is placed in place using a crane to place the equipment at the design point. When the crane is lifted, it must be equipped with professional personnel to conduct the command and protect the equipment. At the same time, ensure that The equipment is placed in a precise position and angle so that the equipment does not touch the surrounding components.

1.2.1 Detection and adjustment stage: Accuracy detection and adjustment is a key link in the Mechanical equipment installation project. It is an important indicator for the quality of the installation project. Inspection and adjustment includes almost all mechanical equipment installation project location accuracy items and some shape accuracy projects. Involved in mechanical equipment installation engineering detection error analysis, dimensional chain principle and mechanical equipment installation engineering precision measurement technology. At this stage of the Mechanical equipment installation project, the relative positional errors between the mechanical equipment and the components, such as the parallelism, verticality, and coaxiality errors, shall be checked. The adjustment of mechanical equipment is based on the technical requirements for the construction of Mechanical equipment installation engineering and the results of mechanical equipment accuracy testing, and adjustment of the mechanical equipment itself and the mutual position status.

1.2.2 Cleaning and assembly stage: For the dismantling of mechanical equipment and the overall mechanical equipment that exceeds the rust-proof shelf life, cleaning and assembly are required. This is a relatively delicate procedure. If the cleaning is not clean or effectively assembled , the equipment will be The impact of normal operation should be based on the design accuracy and structural characteristics of the equipment, and choose appropriate and reasonable assembly and adjustment methods.

1.2.3 Fixing stage: Use bolts to fix the equipment to avoid displacement caused by other forces acting on the equipment. In this link, we must also pay attention to the hidden projects during the installation process. Check before concealing to ensure that the formwork,the anchor surface and anchor bolts are reserved removed. The objects are cleaned and the parts of the embedded anchor bolts are protected and the surfaces of the horns are flattened.

1.3 Trial operation stage: Trial operation of mechanical equipment is an important part of comprehensive inspection equipment manufacturing and equipment installation quality. After the installation of the machinery and equipment is completed, a trial run shall be carried out so that the problems existing in the mechanical equipment installation can be found in a timely manner, and adjustments can be made at any time to ensure that the equipment in operation is in good operation. There are many personnel and professional knowledge involved in this link, which requires meticulous organization and unified command. The specific quality control measures are as follows: First, it is necessary to simultaneously monitor the effect of part of the structure and the overall operation; Second, ensure that the equipment runs evenly if any noise occurs. This indicates that there is a problem with the installation of the equipment and that adjustments need to be made. Thirdly, the temperature of the friction part and the outlet of the air compressor must be accurately measured. If the temperature is too high or too low, it must be controlled.

1.4 Acceptance Phase: As the last link in the construction of Mechanical equipment installation, equipment acceptance can verify and summarize the quality of the previous installation, and it is also a key link in quality control. Construction acceptance shall be in accordance with the provisions of the project. If any hidden dangers in the construction process are found, it is necessary to carry out the shutdown and rectification in time to ensure that the construction quality meets the required standards.

Problems that should be stated during installation

2.1 Inspection and Management of Materials Used

The In the process of mechanical equipment installation, the materials used for inspection and management should be emphasized first. The basis of mechanical equipment is safety materials. Therefore, in the process of controlling mechanical equipment, the materials in the equipment should be controlled first. In the inspection of materials, inspections should not be regarded as too small. Under normal circumstances, the scale of mechanical equipment is relatively large, the types of materials used are also many and each material is closely related to the quality of the equipment. Therefore, each material should be strictly inspected during the inspection. The material to be inspected should be distinguished from the material that has not been inspected. And place the qualified and unqualified materials separately, and make obvious signs. If there are low-quality materials, they should be replaced as soon as possible. In addition, the staff should establish a sense of quality. In the process of installing the equipment, it should also pay attention to the inspection work to ensure that all materials meet the requirements.

2.2 Guaranteed acceptance of equipment installation

The When the installation of machinery and equipment is complete, an acceptance link should be carried out. In this regard, China has promulgated relevant regulations and clearly stated the installation specifications. Therefore, in the specific acceptance process, the staff should strictly check the installation of the equipment in accordance with relevant standards and regulations. A complete device contains multiple parts. After acceptance of Mechanical equipment installation results, each part of the equipment needs to be checked. During the acceptance process, relevant records should be carefully read to check whether there are quality problems in the records. In the installation of some equipment, it is easy to make mistakes. The purpose of the acceptance work is to avoid mistakes or to control the errors within the safety limits, which is conducive to ensuring the safe operation of the equipment.

2.3 Establish a Sound Installation Site Management System

The performance of the machinery, equipment, and equipment management Of the equipment should be taken into consideration in creating the management system. For different types of devices, different management systems need to be formed. In the management of machinery and equipment, it is important to pay attention to the use of different management methods. The managing structure of each device is very different. When managing the device, it is necessary to grasp the basic conditions of the mechanical device and clearly understand the application level of the device. In the use of management systems for the management

In the construction process of various projects, attention should be paid to the quality management of the project in order to ensure the safety of the project, so that the project meets the requirements of relevant regulations and meets the requirement for people.
