Comprehensive guide for the installation and maintenance of the static pressure box
1.1 Determine the installation location
Before installing the pressure box, determining installation location and spatial planning is a crucial step. First, the size, weight and the noise and vibration during operation should be considered to ensure that the selected position can carry the static pressure box and meet its operation requirements. For example, for large static pressure boxes, the ground or platform with strong structure and strong bearing capacity should be selected as the installation position to ensure its stability and safety.
When determining the installation position, also consider the compatibility of the static pressure box and the surrounding environment. For example, the static case should be avoided in environments susceptible to moisture, corrosion or high temperatures to prevent damage or performance. At the same time, ensure that there is enough space around the static pressure box for future maintenance and maintenance work. According to experience, it is generally recommended to keep at least 1 meter of space around the static pressure box.
In terms of space planning, in addition to the size and weight of the static pressure box itself, the layout of the connected pipes, cables and other accessories should also be considered. Reasonable space planning can ensure the smooth and beautiful connection between the static pressure box and the accessories, and reduce the safety risks caused by improper layout.
1.2 Assessment the installation environment
Assess the installation environment and safety requirements before installation.
First, it is necessary to investigate the installation position in detail to ensure that the space layout is reasonable to meet the size and installation requirements of the static pressure box.
Second, the safety requirements cannot be ignored. Relevant safety regulations need to be strictly observed to ensure the safety of personnel and equipment during installation. When assessing safety requirements, consider not only the safety performance of the static box itself, but also the possible risks during the installation. For example, when hoisting the static pressure box, it is necessary to use the hoisting equipment conforming to the safety standards, and to operate strictly in accordance with the operating procedures to prevent accidents.
In addition, a careful analysis of the installation environment is required to ensure that the static pressure box can operate normally and achieve the desired results. Special vibration and noise reduction measures are adopted, and the vibration damping pad and sound insulation materials are installed, which effectively reduces the impact of noise and vibration on the operation of the static pressure box.
1.3 Prepare the installation tools and materials
Prepare the installation tools and materials before installing the is box. First, it is necessary to ensure that all necessary installation tools are ready, including but not limited to electric screwdrivers, wrenches, measuring tools (such as tape measure, horizontal ruler), lifting equipment, etc. The selection of these tools shall be based on the specific model and installation requirements of the static box to ensure smooth progress of the installation process. At the same time, for the installation of large static pressure boxes, professional lifting equipment, such as crane or elevator, may be used to ensure the safe lifting and positioning of the main parts.
In terms of material preparation, in addition to the static pressure box itself and its accessories, the corresponding pipes, sealing materials, fasteners and so on should also be prepared. The pipeline shall be selected based on the fluid characteristics and pressure requirements of the system, ensuring that the parameters such as pipe material, diameter and wall thickness meet the design requirements. The choice of sealing material is equally important, which directly affects the sealing performance and operating efficiency of the system. Therefore, reliable quality and corrosion-resistant sealing materials, such as rubber gaskets or silicone sealing strips, should be selected. The selection of the fasteners shall also comply with the relevant standards to ensure the stability and safety during the installation process.
2.1 Installation and fixing of the base

During the installation of the static pressure box, the base positioning and calibration are a crucial part. First, the space size of the installation position is accurately measured to ensure that the base can be firmly placed and meet the overall layout requirements of the static pressure box. According to the engineering drawings and the actual site situation, use the high-precision measuring tools such as laser rangefinder to ensure the accuracy of the base position.
The base calibration work can not be ignored. After the base installation, level detection to ensure that the base is in the horizontal state. This is because the static pressure box requires high installation accuracy, and the uneven level of the base will lead to the vibration and noise in the operation process of the static pressure box, and even affect the performance of the whole system.
In the process of base positioning and calibration, some successful cases and experiences can be learned. For example, in a large industrial project, engineers used three-dimensional laser scanning technology to make accurate measurements on the installation site, combined with BIM models, so as to achieve high-precision positioning and calibration of the base. The application of this technology not only improves the installation efficiency, but also ensures the stable operation of the static pressure box.

Before assembly, carefully check the model, specifications and quantity of each of the parts to ensure consistency with the installation drawings and instructions.
During the assembly process, the strict process flow and operating procedures shall be followed. For example, when assembling the box, ensure that the connection between the panels is tight and seamless, and use a special sealant to prevent air leakage. At the same time, the installation position and direction of the air inlet and outlet should be accurate to ensure the smooth and uniform distribution of air flow.
Special attention should be paid to the number and position of partitions. The function of the partition is to divide the internal space of the static box into multiple regions to achieve pressure balance between different regions. Therefore, the number and position of the partitions should be reasonably set according to the actual needs. Generally speaking, the more the number of partition panels, the more uniform the pressure distribution inside the static pressure box, but it will also increase the difficulty of installation and cost. Therefore, when assembling the partition plate, various factors need to be considered comprehensively to find the optimal balance point.

Before hoisting, the hoisting equipment shall be comprehensively inspected to ensure that it meets the safety standards and has adequate load-bearing capacity.
During the lifting process, the installation drawings and operating procedures shall be strictly followed. First, the lifting point and lifting path should be determined to ensure that the main body of the static pressure box will not collide with the surrounding equipment or structure during the lifting process. Then, use the lifting belt or the sling to lift the static pressure box body smoothly and slowly move to the predetermined position. In the process of movement, close attention should be paid to the operation state of the hoisting equipment and the stability of the main body of the static pressure box to ensure the safety and error.
When the main body of the static pressure box is hoisted to the predetermined position, a precise positioning is required. This usually requires the adjustment of the static box body horizontally and vertically using positioning tools such as a laser stadiometer or horizontal ruler. During the adjustment process, ensure that the connection between the main body of the static pressure box and the base is close, stable, and meets the design requirements. At the same time, it is also necessary to detect the horizontal degree and verticality of the main body of the static pressure box to ensure that it meets the installation standards.
