The long shaft diesel engine fire pump is composed of multiple centrifugal impellers and guide shells, ascending pipes, drive shafts, pump seats, motors and other components. The pump seat and the motor are located above the pool. The power of the motor is transmitted to the impeller shaft through a transmission shaft concentric with the riser pipe, thereby generating flow and pressure.


具体内部结构如下: The specific internal structure of the long shaft diesel engine fire pump is as follows:

a) Motor: hollow shaft motor (YLB type) for deep well pump, or ordinary vertical motor with solid shaft;

b) Adjustment nut: adjust the axial string of the impeller;

c) Pump base: bear heavy load, and easy to install stuffing box;

d) Pre-lubricating wire plug: Before starting, pour clean water through it to lubricate the internal bearings of the pump;

e) Upper short pipe (short pipe B): flange connection method, the upper flange of the short pipe is connected to the pump base, and the lower flange is connected to the riser flange;

f) Impeller shaft: 2Cr13 stainless steel;

g) Middle shell: smooth flow channel, reducing friction resistance and improving efficiency. Material: QT450, 2Cr13, 304, 316, etc .;

h) Impeller: Designed in cooperation with the middle shell, the working range is wide, and precise calibration is performed to ensure stable operation. Material: silicon brass, QT450, 2Cr13, 304, 316, etc .;

i) Middle shell bearing: copper bearing or wear-resistant rubber bearing. Reliable work and long life.

j) Taper sleeve: Fix the impeller on the impeller shaft reliably.

k) Lower shell bearing: copper bearing, grease filled, long-term trouble-free operation.

l) Lower shell: Direct the liquid in the water filter to the impeller with a relatively small loss. Material: QT450, 2Cr13, 304, 316, etc .;

m) Water filter: The length of the water filter should be appropriate, and it can prevent large particles from entering the pump;

n) Transmission shaft: high-strength carbon steel, the surface of the bearing position is chrome-plated. Available in stainless steel as required;

o) Lift pipe: The lift pipe can be installed by screw connection or flange connection.
