Product Detail
BJWG Series Network Overlying, No Negative Pressure Freque
BJWG Series Network Overlying, No Negative Pressure Frequency Conversion Water Supply Equipment Selection
Description:
Model meaning:
Selection explain:
1. According to the actual engineering building door model, calculate the number of water and the largest water flow, general need supply pressure, flow rate shall be calculated by the institute of decision, such as design institute no arguments are given, the company will according to the actual situation, according to the < < building water drainage design specification GB50015 > > calculation income
2. Regulated storage tank should be rated pressure according to the actual engineering required pressure configuration, size selection may refer to relevant diaphragm type pressure tank selection mode.
3. Steady flow tank selection
Steady flow tank volume (V adjustable t) should be according to the water inflow and water yield change curve through calculation, sure, should press type calculation:
V adjustable t = train Q * train t
Type: V adjustable t --, steady flow compensator control volume (m3);
Train Q - design of water flow and water flow out of balance (m3 / h),
The equivalent of the size and the actual water supply number, water resources, local water habit, user properties and the other factors, such as season, general (forty - 300 households) take train Q = 2-4 m3 / h, (350-700 households) take train Q = 4 to 8 m3 / h, (700-1500 households) train Q = 8-16 m3 / h, and so on.
Train T - water peak pressure continuous wave time (h),
Generally take train T = 3-5 min, special circumstances should not be more than twenty min.
When the steady flow tank water into water shortage because of the low water level limit beyond jar, low water level alarm start, and automatically shut down equipment.
4. Such as system adopts stratified zone water supply mode, please let us know the specific division method and a few floor level.
5. Control system components points domestic and imported two kinds.
6. Equipment materials for meeting the requirement of food sanitation materials; If customers have special requirements, please directly give clear technical requirements, as the procurement contract attachment.
7. Schools, hotels and other consumption highly centralized place, should be based on the actual water point on how much the largest hours flow calculation.
8. In order to facilitate customer easy choice water supply equipment, our company made a reference number and flow and the corresponding steady flow tank configuration corresponding selection table, as a summary on the selection of parameter table, the table can according to the customer to provide the number of users, and pick a non-negative pressure method of water supply equipment corresponding flow rate and the number of pump and the recommended steady flow tank model, and then according to the building floor height to calculate the water supply equipment required lift, then choose relevant pump factory corresponding model of the customer, can complete set no negative pressu
