Non negative pressure integrated pump set Manufacturer It is a new electromechanical integrated water supply equipment composed of computer technology, frequency conversion technology and motor pump, to meet the requirements of urban water supply network that water pumping does not produce negative pressure, but also has a certain capacity of regulation and storage, and water supply is cut off during peak periods. Scope of application of integrated pump set: 1. Scope of application: it is applicable to pressurized water supply in areas with sufficient urban pipe network pressure. 2. Applicable project type: large intermediate booster pump station for production and domestic water of industrial and mining enterprises, and water supply of waterworks. 3、 supply Non negative pressure integrated pump set Applicable project position: water supply secondary pressurization system. 4. Other scope of application: domestic water for public buildings such as newly-built, reconstructed and expanded residential buildings, office buildings, hotels and restaurants. 5. Type of using unit: design unit, construction unit and supervision unit.

Non negative pressure integrated pump set Manufacturer General provisions: equipment discharging heat, steam or harmful substances, supply Non negative pressure integrated pump set Local exhaust should be adopted. When local ventilation can not be used or local ventilation can not meet the health requirements, it shall be supplemented with all-round ventilation or adopt all-round ventilation. The air distribution design shall be optimized according to the characteristics and changes of pollutants, and the normal operation of local exhaust system shall not be damaged. At the same time, when releasing waste heat, moisture and harmful substances, the ventilation volume in all aspects shall be determined according to the large air volume required. When the quantity of harmful substances cannot be determined, the ventilation volume in all aspects can be determined according to the ventilation frequency. All kinds of pump rooms in the domestic sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled. All pump rooms in the oily sewage treatment station should adopt natural ventilation. When mechanical ventilation is adopted, indoor air should not be recycled, and the ventilator and motor should be explosion-proof and directly connected.

1、 Non negative pressure integrated pump set Manufacturer Location selection. supply Non negative pressure integrated pump set It is the core part of the water supply and fire fighting pipe network of the whole building or the whole community, plant area. The location of the pump room should be selected not only to facilitate the laying of the water supply and fire fighting pipe network, but also not to have noise impact on rooms with quiet requirements. It should also try to minimize the occupancy of valuable buildings (such as shops and parking spaces). The domestic water supply pump room and fire pump room should be built together, which can not only save land, but also facilitate maintenance management. For a residential area, the pump room is often designed in the equipment room of the underground garage, and is combined with the generator room and other electrical and air-conditioning rooms in the same fire compartment. And the pump room should be as close as possible to the middle of the large water users or the whole community, which can reduce the length of the main pipe and reduce the head loss of the pipe network. The outlet of the pump room shall be directly connected to the outdoor or the emergency exit. If the pump house is located in a civil building, it should not be adjacent to the neighbor's house or on its upper or lower floors, and the pump house should be located in a well ventilated room without freezing. The size of the pump room is determined by the layout of the living pool, fire pool and pump set.

1. To ensure the safety of the pump room, the pump room must be locked. 2、 Non negative pressure integrated pump set Manufacturer Safety Operation Regulations, Hygiene and Safety Management System for Secondary Water Supply, Patrol Inspection Specifications, Water Quality Inspection Record System must be posted inside. 3 supply Non negative pressure integrated pump set The following record files must be available inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must have a pressurized area mark, and the corresponding control system should also have a pressurized area mark: low area, middle area, high area, etc, Mark the product model, qualified number, ex factory date, etc. 6. Water pump identification: the number of pumps must be painted on each pump; For example: 1 # pump, 2 # pump, 3 # pump, 4 # pump, 5 # pump, words. 7. "Normally open" signboard of inlet and outlet valves; 8. The pipe shall be marked with water flow direction arrow; 9. The prefabricated energy-saving pump room needs a drainage system 10. The energy-saving pump room can realize on-site control and remote monitoring;
