Internal structure of Sham Tseng fire pumps of diesel engines

A) gear box: pump of special hollow shaft gearbox (H);

B) adjustment nut: adjusting the impeller axial series;

C) pump: subjected to heavy loads, and easy stuffing boxes;

D) pre lubricated plug: before starting, which injected clean water-lubricated pump bearing;

E) short tube (short Guan Yi): flange connection, short flange on the tube and the pump connection, flange with ascending pipe flange connections under;

F) impeller shaft: 2Cr13 stainless steel;

G) shell: smooth flow channel, reduce friction and improve efficiency. Material: QT450, 2Cr13, 304, 316, etc;

H) impeller: Shell design, high efficiency, wide operating range, and precision-balanced to ensure smooth operation. Material: silicon brass, QT450, 2Cr13, 304, 316, etc;

I) shell bearing: bronze bearings or wear-resistant rubber bearings. Reliability and long service life.

J) taper bushing: reliably fixed on the impeller the impeller shaft.

K) lower bearing: bronze bearings, grease filling, long trouble-free operation.

L) lower housing: filter water in the liquid evenly into the impeller with minimal losses. Material: QT450, 2Cr13, 304, 316, etc;

M) strainer/colander: filter network length should be appropriate to achieve the best and can prevent large objects from entering the pump;

N) shaft: carbon steel with high strength, chrome plated bearing position. Depending on your needs, offers stainless steel;

O) ascending pipe: ascending pipe can be installed with threaded connections can also be installed by flanged connections.
