3. Handling of pump (Discharging with multiple pumps)
In the mountains and forests or in urban areas which are inconvenient for water
transportation, multiple pumps will be required in order for the water to reach the
fire by relaying the pumps. In this case, pumps are separated far from each other
and firemen are required judgment based on the existing state and systematic
activities based on training. General method of relay operation is described below.
1. Installation
(1)
Determine the number of pumps and places of their installation depending
on the number of extension hoses and height from the water source.
(2)
Screw in the coupler to the water suction port to connect the fire hose.
(3)
Fit a two-way valve to the coupler of the water discharge valve beforehand.
The hose coupler may not be removed until the water in the hose is drained
after the water is discharged.
2. Operation (Necessary an operator for all of pump each)
(1)
Open the water discharge valve or all sub-pump in advance.
(2)
Send water to the original pump first and then to others sequentially.
(3)
Check the pressure scale in the sub pumps and increase the engine speed
regulate the discharging water.
The sub pump: Should be more than 0.05MPa in a scale of compound
gauge pressure, be less than 1.2MPa in a scale of power.
(4)
If there is not enough the power of water discharge at the tip of hose,
increase the engine speed of the original pump, then the second of one
which is closer from the original, sequentially.
(5)
When stopping water discharging, decrease the engine speed of the last
pump first and stop gradually.
○
If the nozzle at the end of the hose or water discharge valve is closed while
water is being discharged, the pressure in the pump may increase
extraordinarily, and the pump or hose may be broken.
