A taste of life conversion water supply equipment, water, city life, the continuation of pump life, living water Which election, far Division inject quality, only for the quality of life, good frequency selection Yuanke, frequency conversion water supply equipment is far by the company for many years to technology innovation, quality attention to the future, the frequency of water supply equipment complex piece of old times in the fertile soil, first-class equipment engineers use their wisdom and skills to create a well-bred qzg excellent quality conversion water supply equipment --- Frequency Yuanke water supply equipment, and continue to perform a "conversion water supply equipment" legend. Equipment characteristics, structure and working principle: the main fire pumps, fire standby pump, regulator pump, pressure tank, a pressure sensor, control cabinet and other components. Usually by the regulator pump pipe network pressure is stable at the set value, when the fire extinguishing the fire main pump starts automatically. When the main fire pump failure, fire standby pump automatically put into operation. With dual power switching device, when the main power fails, the standby power can be switched automatically. Fire water system design is an important part of the engineering design of coal, coal with the development of infrastructure and science and technology, increasingly stringent requirements for fire protection systems, building fire safety regulations issued by the State constantly updated, but the coal industry is lagging behind the design specification updates, design selection of standards confusion often. Combined with existing national and industry standards for coal fire water system design, specification execution differences pointed to clarify the fire water system design point of view. Hezhou automatic diaphragm pressure water supply equipment Coal Fire interior design high-rise industrial buildings can be partitioned pipeline pump water systems and fire protection systems independently set high zone, and whether to set a separate area of ??high fire fighting system is debatable. "Coal Regulation" high-rise industrial buildings is set independently interior fire protection system does not explicitly require, "Building Regulations" Article 8.1.2 should set up a separate system, there is no more independent settings in coal engineering design, are used in combination Fire domestic water supply systems, industrial venues towers or high water tank, fire pump partition way for the pipeline, according to the fire main pump head low pressure area fire protection design, high-rise building fire at the beginning of the initial fire 10min meet the high pressure zone through the fire started the fire button to start the pipeline booster pump while in the main fire pump starts pumping stations pipeline pump relay through the high pressure area to ensure high indoor fire zone. Above the fire water system is currently used more, compared with the advantages of an independent fire protection system is to save the high zone main fire pumps, fire water tank and outdoor pipes, is technically feasible, there is a problem: ⑴ and "Building Regulations" 8.1. 2 contrary, indoor fire pipeline can be set independently, but the system must be combined outdoor pipes. ⑵ single industrial site for high-rise buildings, just set up a group of pipeline pumps, fire water supply equipment if there are several high-rise buildings were set each indoor pipeline pumps were unable to set up regional high water tank and regulator device. Under ⑶ pipeline pump located in the interior, fire water supply equipment and its role as the main fire pump high zone, due to the initial fire 10min fire water must only be achieved through open pipeline pumps, and in the construction of the coal industry generally does not set alarm premise, either or by starting the fire button and pipeline pump linkage by remote control, are likely to be adversely affected in real time for the best fire, and must at the same time to start the fire main pump, resulting in high-rise industrial building fire required secondary pressure Shaanxi two starts ?? pumps, can not form a rapid fire. ⑷ pipeline pump located in the high-rise building, away from the fire control center, maintenance and management are difficult to pay attention, pipeline pumps disrepair may cause significant security risks. In summary, I believe that the coal industry rise buildings should set up a separate fire water system. Hunan intelligent box pumping station: "Coal Regulation" No detailed provisions outdoor fire system architecture can be used in the coal industry, the author based on years of design experience, combined with the coal project design features, make the following point of view. Often high-pressure water supply system: combined system saves pipeline investments, is "Building Regulations" water system (8.1.2) is recommended, and can be used for high pressure fire fighting system of mine, I think we should adopt the fire outside the network combined piping systems, indoor Fire and water supply systems and living apart, indoor production and domestic water supply using vacuum valve. Equipment installation sequence: 1R entire pump transported to the site. Persons have been installed with the base motor. Can not remove the leveling base-inch pumps and motors. 2R? Will base on the foundation. In the vicinity of the wedge-shaped horn pad ground screw. To elevate the base about 20-40 mm. Filled with screw slurry of water after preparing leveling. 3R? Levelness with a spirit level to check the base. Pull tight to the foot after leveling nut filled with water base mud. 4R? After three? Four days to dry cement. Then check the level of degree. 5R? The base support plane. Pump feet. Motor feet flat on the dirt washed clean;,. And the pump and motor on the base. 6R? Adjustment shaft level. Tighten the nuts properly after leveling. Prevent the move. To be installed after the motor adjustment. Pad at substandard levels of iron in between, pumps and couplings leave some space. 7R the flat foot on the coupling. Check the pump axis is coincident with the axis of the motor. If re-sets. At the foot of the motor or pump pad sheet, so that the two couplings with cylindrical and flat-foot level. Then remove the pad a few slices of thin iron plates. After a plane with a piece of iron to replace the iron plates. And re-check the installation. In order to check the accuracy of the installation. In several opposite position with a feeler. Measuring the gap between the two coupling plane. Coupling plane one week on the maximum and minimum gap difference not more than 0.3 mm. Difference at both ends of the horizontal or vertical centerline shall not exceed 0.1 mm. Water supply equipment installation requirements: 1, before installing the pump abortion should be carefully examined whether the hard thing, to avoid damage to the impeller and the pump is running. 2. When installing piping reasonable amount shall not be allowed on the pump, the pump in order to avoid distortion, affecting the normal operation. 3, tighten the bolt, so as not to affect the performance of the pump vibration when starting. 4, in the inlet and outlet piping pump installation control valve, pressure gauge installed in the vicinity of the pump outlet to control the pump operates within its rated operating conditions to ensure the normal use of the pump. 5, the discharge pipe loaded check valve should be installed outside the gate. 6, the installation of the pump at the second pressure pump works: Under normal conditions, the regulator pump frequency operation, the pressure needed to keep the fire protection system. When the fire broke out, the fire spread to the signal control cabinet, automatically open Shaanxi secondary pressure pumps, pressure main fire pump controller ensures constant-frequency operation. Fire regulator water supply equipment production is a new type of automated fire sprinkler water supply equipment. It uses advanced technologies crisis control. Constant pressure control or intelligent power frequency control. It can receive external signals button hydrant, fire control center to start the fire equipment. Firefighting equipment can automatically activate the fire pipe network pressure situation with the pool water level. Locked by the pressure signal to determine the time and the number of units in operation of the pump. To meet fire needs of the system. The system is usually to maintain the fire pump system pressure by the regulator. This equipment has been Ministry of Public Security, "national fixed fire extinguishing systems and fire-resistant construction of Quality Supervision and Inspection and Testing Center" Monitoring qualified.
