NTRODUCTION
The creation of water transmission machines and
the lightness of the workflow have created
problematic situations in the history of mankind.
A water transmission machine called a sink and
Noria, which is propelled by human or animal
power, was used in Egypt thousands of years ago
BC. The water-bearing Carpenter, using his
chimneys to mechanically move the fluid
movement, was used in irrigation of crops in
ancient times in Central Asia, India, China and
Egypt, reaching the present day 4 .
In the XVII century, L.Euler founded the theory of
shovel pumps and used this theory to establish
a.A.Sablukov created a sample of the centrifugal
pump in its current structure. With the invention
of electric motors in the 19th century, porcelain
pumps began to be replaced by centrifugal and
axial pumps, which were much more compact,

lightweight and inexpensive in comparison to
them.
In Uzbekistan, at the beginning of the 20th
century, there were pumping units powered by
small oil engines. T. in the 1930s.A.Under the
leadership of Kolpakova, work was carried out in
our republic to design, build and Research simple
pumping
devices
powered
by
tractor
engines 10 .
The first electrification immovable pumping
stations are “Bayavut” in Mirzachul, built in 1959,
and “Torakurgan pumping station " in Fergana
Valley.
Today, the “Syrdarya Sokh irrigation systems
Basin Directorate, Fergana Pumping Station
Energy Directorate”
is operating in Fergana
Valley.
Mainly centrifugal pumps are operating in
pumping stations due to the current situation.
A practical visit to the “Faiziabad” pumping
station was organized. Centrifugal pumps
through asynchronous and synchronous electric
motors with a power of 6 kV with a power of 5
630 and 5 800 kW are working in a parallel state.
The main task of pumping units is to supply water
to agricultural irrigation systems.
The building of the pumping station was
completed in the middle of the XIX century. In the
building of the pumping station there are 10
pumping units, all pumping units are centrifugal
NAOS. The pumping units are equipped with 5
synchronous electric motors with a power of
630kw and 5 asynchronous electric motors with
a power of 800 kW. The pumping unit throws 500
liters/sec of water from the lower byef to the
upper byef.

the current repair, it is carried out after stopping
the aggregate and drying the water, partially
disassembling the details. Overhaul. Based on the
data of preventive monitoring of pumping units
and control of energy characteristic, a capital
repair plan is drawn up and approved by higher
organizations.

Another of the main characteristic features of
increasing the efficiency of pumping units is the
correct Organization of the use of the pumping
station. In order to ensure the effective use of
pumping stations, administrative
–
managerial,
direct management and repair work should be
organized.
C
ONCLUSION
In conclusion, it should be noted that the scope of
the above work directly depends on the
professional management strategy of working
personnel working at the pumping station and the
knowledge of specialist personnel. Alternatively,
it will be mimkin to achieve an extension of the
process of operation of pumping units by timely
implementation of seasonal and annual capital
repair processes of pumping units at pumping
stations.
