Water quality standards for hot water boilers and installation requirements and installation plans for pump installations.
Steam boilers are the main boilers for commercial and residential water use. However, from the point of view of boiler explosion accidents and boiler corrosion in recent years, many steam hot water boiler workers are not familiar with or are not familiar with the maintenance and use of Zhongchuang electromechanical boilers. Therefore, the electromechanical technicians of this paper first introduced the water quality standards of steam hot water boilers.
The main requirements for steam boilers are as follows:
1. When the rated evaporation of the boiler is greater than or equal to 6t / h, the boiler should be degassed. If the boiler with a rated evaporation of less than 6t / h, if local corrosion is found, the water supply should be deoxidized and the oxygen content of the boiler boiler feed water. Should be less than or equal to 0.05mg / L.
2. If it is difficult to determine the dissolved solids, it can be indirectly controlled by measuring conductivity or chloride ion (C1-), but the relationship between dissolved solids and conductivity or the ratio of chloride to Cl- should be tested. According to the test. determine. This ratio relationship should be retested and corrected periodically.
3. It is possible to control the relative alkalinity of the all-welded structure boiler.
4. Steam hot water boilers and steam-water dual-purpose boilers with rated evaporation less than or equal to 2t / h and rated steam pressure of 1.0MPa or lower (if there is no special requirement for steam and water quality) can also be treated with pot. However, it is necessary to supervise the scaling, corrosion and water quality of steam hot water boilers, and do the ingredients, sewage and cleaning work.
Pump unit installation requirements and installation plan
Installation requirements
The installation unit has technical strength before installation, carries out installation and construction organization design, and formulates the installation and construction network plan.
The supervision engineer shall organize the design, manufacturing and construction units to conduct technical exchanges and coordination according to the specific conditions of the pumping station. After the installation and construction organization design approval, the supervision engineer will issue a start order, allowing the construction unit to enter the site for installation and construction.
Construction units should be established, a single project leader should be established, and the scope of duties should be clearly defined and unified.
