Price:Stainless steel fire tank
Product introduction:Suzhou Shanghai stainless steel factory, stainless steel water tank fire water tank, fire water tank, stainless steel manufacturers, the price of the heat preservation water tank, water tank, washing tank, stainless steel cylindri
Indoor fire water storage in low rise building should be stored for 10 minutes. High building fire water tank storage, a type of building should not be less than 18 cubic meters, two types of construction and a residential construction should not be less than 12 cubic meters, two types of residential buildings should not be less than 6 cubic meters. The installation height must be satisfied with the water pressure of the indoor hydrant installed at the most disadvantageous point.
Stainless steel fire water and other water with the same water tank, should not be moved to ensure fire water used for technical measures, such as the outlet of other water high fire water water; but when the storage of fire water, only by the lower part of the water table calculation.
Such as stainless steel fire water tank can not meet the most unfavorable point of hydrant water pressure, can set a fixed fire pump or pressure tank, partial pressure. If water tank is adopted, water quantity and water pressure of fire water should be guaranteed. Such as the use of fixed fire pumps, fire hydrant should be in lack of water (including more than 6 layers of unit housing, more than 5 layers of other civil buildings and more than 4 levels in the warehouse each fire hydrant, fire pump set) remote start button; and in order to prevent the pressurized water poured into the water tank, should also be set the check valve in the outlet pipe of the water tank on fire.
The pressure water tank is a fully automatic partial pressurization water supply device. The basic principle is that a pressure air energy storage tank is additionally arranged between the water pump and the water supply pipe network. Divided into non diaphragm type and diaphragm type of two. The utility model is composed of an air pressure tank, a water pump, an electric motor, a control cabinet, an automatic air supply device, an air filter, a pressure gauge and a controller.
Stainless steel fire pump is to ensure the indoor water supply network pressure and flow of machinery and equipment, in order to ensure the continuous supply of fire water, fire water pump to meet the following requirements:
1. a group of fire pumps should have at least two suction pipes, one of which fails, the remaining suction pipe should still be able to meet the fire water supply requirements. Each fire water pump of high pressure fire water supply system shall have independent water suction pipe.
2. stainless steel fire water pump suction pipe and outlet pipe, for easy inspection and maintenance, generally should be laid on the ground floor of the pump room, its valve should be located in convenient place, and need obvious signs of opening and closing.
3. stainless steel fire pump suction pipe bore shall not be smaller than the diameter of fire water pump intake.
4. stainless steel fire water pump should be self irrigation, in order to ensure timely water supply, generally should be within 5 minutes after the alarm can start the work. In order to ensure normal operation in any situation, two power or equipment shall be provided with internal combustion engine power.
5. stainless steel fire pump and power machinery should be directly connected, if there are difficulties, you can use no less than 4 V-belt drive, so as not to slip.
6. fixed fire pumps should be installed in general standby pumps, standby pump capacity should not be less than the main pump.
7. stainless steel fire water pump outlet should be equipped with check valve and test for inspection of the drain valve.
The fire pump high pressure water supply system to maintain the pressure, in normal operation, should be monitored or check whether the pump unit is abnormal noise or vibration strictly, bearing temperature exceeds the allowable value (up to 75 DEG C), various monitoring instruments are normal. Standby pump and temporary high-pressure water supply system of fire pumps, irrigation conditions, power equipment should maintain good combat readiness, fire alarm can start immediately.
