No pumping station: water pump and the pump chamber is placed in underground tanks, pumping stations and fixed in the integration of the Ministry of items, only with a tank capacity of 0.5m3 ~ 1m3. 2. Resistance to use: a combination of stainless steel water tank BDF assembled without welding, buried no oxidation, hot-dip galvanized cabinet plus bitumen spray corrosion, high strength, long life, no rust, no leakage, easy installation. 3. Easy emptying: This product is the use of submersible fire pump, submersible directly on the water, no air emissions, no cavitation. 4. No risk: Integrated Pumping integrated buried in the ground, to avoid the reinforced concrete underground pumping station frequently flooded during the rainy season pond leakage or other accidents. Submersible pumps are also not because the air is humid motor insulation performance degradation, causing the device leakage, can not enter the fire condition. 5. anti-cracking: diving fire pump placed in the depths of the tank, water tank buried in the ground 60 ~ 80cm or less, will not freeze in winter, the water pump is not cracking. ① mechanical flushing head and ion rods at the top of the tank uniform (usually meet with a volume of 25 cubic meters of water tank) 1. This equipment with advanced technology, reasonable design, reliable operation, the water pressure is stable, low noise, no secondary pollution. 2. The device is compact structure, small size, light weight, small footprint, low investment, quick to install, easy to maintain, easy centralized management. 3. The high degree of automation, protection functions, with undervoltage, overvoltage, overload, overcurrent, overheating, short circuit protection. Pump programmable controller, switching accurate, by one soft start to reduce the impact on the grid, because the pump is running at high efficiency conditions, significant energy saving effect. 4. With automatic, manual and remote control three operating mode, in any case continue to water supply system. 5. This device has a fire control center networking and control functions, and have dual power supplies and can automatically or manually switch, the device has a standby pump automatically put into operation function, the entire pump with periodic inspections scheduled automatic function. The device specifications, sub-urban and rural areas can be widely used file reasonable residential, industrial and mining enterprises, commercial buildings, hotels, military facilities, high-rise building fire protection engineering. Automatic Fire constant pressure water supply equipment, frequency control and automatic control technology, the implementation of closed-loop control of the water supply system in the pump unit, which is set according to the pressure difference between the water supply pipe network and systems the actual pressure value, by analog and logic operations PLD regulator, the results gave the programmable controller and inverter, converter and programmable controllers by the water supply system of pump units and pump motor speed, thus ensuring the supply of the entire water supply system pressure and the set value.
