rature of the liquid is not over 80 C. The pumps are suitable for

water supply and drainage in mines, factories and cities.

The erection height of the pump, that is the vertical distance

from the sucked liquid surface to the pump shaft should be less

than it which should be taken into consideration for users to se-

lect the pump, is calculated per the following formula:

Hsz Ha-Hv- Hs-(NPSH)r

Of which:

Hsz-- the erection height set with the pump(m)

Ha--- the head of the atmospheric pressure under the

conditions on the spot of use(m)

Hv--- the head of the vapourized pressure under the tem-

perature of the liquid being umped(m)

Hs-- the lost head of the suck-in pipeline(m)

Model MD pump consists of four parts, stator, rotor, bea-

ring and shaft seal:

1.Stator consists of inlet, middle and outlet sections and

the guide vane etc., with the take-up bolt tightly clamping

all sections to form a working room. The inlet of it stands

horizontally while the outlet vertically upward.

2.Rotor consists of the shaft, impeller, balancing disk and

muff etc., the shaft passes the power to the impeller to have

it work; the balancing disk balances the axial force; and

replaceable muff is mounted on both sides of the shaft to

protect it.

3.There are rolling and sliding bearings:

The rolling bearing consists of bearing seat, bearing and

bearing gland and uses grease for lubrication.

The sliding bearing consists of bearing body and cover,

liner, dust-proof disk, oil leveller, oil throwing ring etc., and

uses thinned oil for lubrication.

4. The shaft is sealed with stuffing and the shaft seal consi-

sts of the sealing contents, stuffing, baffle. The liquid in

the sealing work-room functions water-sealing, water-

cooling and water lubricating and the water for water-

sealing comes from the pressure water inside of the pump.

In addition, the pump is directly actuated by the prime m-

over through the elastic clutch and, viewing from the prime

mover, moves CW.
