Hii everyone
My previos mail in this forum was regarding a temporary fire pump(only dieselPump) only. we have installed this fire pump for temporary fire fighting in the site. The pump is 500 USGpm @ 20 Bar.(NOn Listed).The risers we have installed up to 7 floors now. The pressure switch setting is kept such that when presuure drops below 16 Bar the pump automatically starts. For the last 2 days we are seeing that the pump starts automatically at night time.In the daytime there is no considerable pressure loss also. our initial assesment was that it may due to air trapped inside ,as a result we installed air release valve in both risers .Also the NRV in the pumpdiischarge was replaced to ensure there is no leakage. Any guesses on whtmay b the reason? _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
