When you need fire pump type selecting, we will provide the before-sales service such as price of fire pump model, fire pump, in order to offer your referenced alternative. This product information is the knowledge that suggests about type selecting of XBD fire pump:
Fire pump and life water pump and photograph of manufacturing water pump are compared, on function due higher demand, but the performance that our country shows a normative offset to prevent pump and test ask to did not make more detailed special provision, cause fire pump to be not had when choose according to can be being checked, appeared a variety of problems.
To the function of fire pump the regulation is as follows: Of the flow that water pump gives discharge to be nodded for job of make choice of 150% when, 65% of the lift that the job that its lift is not less than make choice of orders, 140% what the lift when shutting water pump orders lift at job of make choice of not quite. Its are actual was to stipulate the function curve of water pump is a flowing curve. Our country standard does not have detailed regulation to fire pump, cause fire pump choose on have many discrepancy. The proposal designs the regulation of NFPA20 of the reference when personnel is being designed.
” expensive plan ” and ” build compasses ” did not test a requirement to the function of fire pump, NFPA20 regulationFire pumpIn piece set on conduit measure with flowmeter. 175% what flowmeter should check discharge of water pump make choice of, fire pump is in a pressure table that the diameter should set to be more than 100mm on conduit, such water pump can check the performance of water pump after installation, whether can so that be informed,satisfy design requirement. The proposal designs personnel to consider this issue in the design.
According to investigation, the discharge of pump of domestic and international stabilized voltage is chosen more for 0.5L/S-2.0L/S between, stop pump to have water hammer appearance when the system does not have baric canister. Having the demand of custody and automata function to the system in view of stabilized voltage pump. We suggest the discharge of stabilized voltage pump is 1.0L/S-2.0L/S, pressure is than advocate pump tall 0.1Mpa-0.2Mpa perhaps gives priority to pump 1.1 times – 1.2 times. Stabilized voltage pump is better set baric pot, if do not set baric pot, answer to make a text on the controller of stabilized voltage pump, those who make is unapt when stopping pump start often because of water hammer action.
Thank you to be mixed to the visit of above content very much read!
