Hydraulic calculation of the fire extinguishing system of port facilities
The purpose of the article is to develop an algorithm for calculating the hydraulic characteristics of a fire extinguishing system for port facilities. The fire extinguishing system has a submersible pump, pipelines intended for transporting water from the place of its intake to the place of possible ignition. The UGP-M-1210-04 pump is used. Research objectives: analysis of test results; obtaining empirical dependencies of pump performance indicators on its performance, research of pump operation in the network. Calculations of the velocity of the expiring jet and the total reactive force at the working point of the pumping unit are carried out. The effect of velocity on the reactive force is investigated. Analysis of the results shows that the accuracy of calculations is acceptable for engineering calculations. The resulting calculation algorithm can be used in the design of fire extinguishing systems in port facilities.
