Vansan Pumps is the first geothermal down hole pump manufacturer in Turkey. Vansan
geothermal pumps are successfully used up to 150º C geothermal fluid temperatures
since 1984. In many district heating systems and green house heating systems..

 

Main problem of down hole Pumps is elongation differences between column pipes and
column shafts during start up, which should be taken care of during construction. In all
wells there is a big water temperature difference between well bottom and well top.
Before the pump is started position of impellers in pump bowls is indicated in (figure 1).
When the pump is started column shaft elongates under the down thrust forces (figure
2). When hot geothermal fluid rises up and reaches the pump after a short time.
Because of area of column pipe per unit mass is much greater than the column shaft,
column pipe elongates more than shaft in a short time results, the pull up of impellers
in bowls (figure 3). After the column shaft heats up and shaft and pipe temperatures are
equal, impeller resumes its original position in bowls (figure 4).

Geothermal Discharge Head Assembly

Discharge head must be rigid enough to carry the weight of the complete pump and
motor and axial thrust. Bottom flange must seal the column pipe to allow pressurization
of column to prevent the boiling of geothermal fluid in the well and should not transmit
the heat from the fluid to the motor. Also carry the axial thrust bearing system and
column pipe stretching systems. Discharge piping should not transmit any torque to the
discharge head.

Inhibitor piping and water level measuring system

There are two small pipes running
alongside the column pipe in the well. One is for inhibitor injection and the other for
dynamic water level measurement. Injection piping must be long enough to prevent
calcification approximately 50 m. lower than phase separation level. Dynamic water
level measurement system is also used for annulus pressurizing. Both piping may be
combined by installing a header system at the well head

Pump Assembly

Pump assembly consists of suction case, intermediate bowls and
impellers and discharge head. Pumps are designed to deliver
the required capacity at the required head. Beyond of this basic requirement
another important requirement is to minimize the life cy
geothermal pump. To achieve this important requirement pump must
be designed and selected to work efficiently over the whole range of
frequency controlled operating conditions.
