[Quanquan fire pump] fire pump acceptance is to pass the national test found that when the arrival of the construction site need to issue a corresponding fire inspection report. Therefore, the quality requirements of the fire pump is relatively high. Its performance parameters and technical indicators meet the relevant standards, with high efficiency, low operating noise, good anti-cavitation performance, reasonable structure, long life and other significant advantages. Below for everyone to introduce about the fire pump model and maintenance issues. Fire pump maintenance: Before assembly, it is necessary to clean the assembled parts, familiar with the design drawings and selection before cleaning, to confirm that the model and design of the fire pump are in conformity with the product certification. Production license, test report and product assembly drawing And manual. Cleaning should be cleaned according to the assembly sequence. And applied to the appropriate grease, the device has been installed on the original parts should be a comprehensive inspection of cleanliness; if not required should be cleaned. Equipment assembly should first check zero, parts and assembly related to the appearance of shape and size accuracy, to confirm compliance with the requirements of the assembly. Fire Pump Selection Problem: Fire pumps are not used to keep the sprinkler system and hydrant system at the required pressure conditions and to meet the hydraulic and water requirements for fire fighting water once it is out of service. Its role is very obvious, so the standard refers to booster pump, essentially refers to the regulator pump, especially the automatic sprinkler system, the pressure pump fire pump flow value depends on many factors, in our selected model There are several important factors to consider: (1) Category of fire protection system: When a fire pump is used in a sprinkler system, consider the amount of water in a sprinkler; and for a fire hydrant system, consider the amount of water in a fire hydrant. To determine the size of traffic. (2) Whether there is air pressure water tank matching settings: No air pressure water tank supporting the setting, the fire pump flow by not more than a nozzle or a hydrant water quantity calculation. A gas tank equipped with water, the system of water supplement and pressure assurance is carried out by the pressure tank, the pump flow only to meet the pressure on the flow of water tank requirements, that is, the pressure pump flow should consider the pressure of water Adjustable volume of the tank factors. At this point, the regulator pump flow should be calculated according to the total volume of air and water tank and the volume of water inside the tank. Pump water should be when the tank is the average pressure, not less than the maximum hourly pipe network traffic 1.2 times. These are my company's fire pump model and maintenance problems made a little summing up, I hope our customers after reading some understanding.
