Reference: bowl head calculation

Reference information:
For vertical turbine pumps, discharge head equals bowl
head minus lift and internal pump loss. It can be shown as:
hD = hB - hL - hP
Where hD = Discharge head. Pressure gauge reading in
PSI multiplied by 2.31 for fresh cool water.
hB = Bowl head. Actual head in feet developed by the

bowl assembly.
hL = Lift. Elevation difference in feet between the pumping
water level and the pressure gauge.
hP = Internal pump loss. Pump column loss plus
discharge head loss in feet.
Conversely, bowl head equals discharge head plus
lift and internal pump loss.
hB = hD + hL + hP
NOTES:
1. Test curves are plotted as bowl head (hB).
Allowances must be made for lift and internal
pump loss when comparing test curves to field
performances

http://bzno.com.ua/podbor-nasosa-dlya-skvazhiny Рис. 1. Печать

1 — газовая труба;

2 — фланец;

3 — деревянный диск;

4 — кровельное железо;

5 — мыло или пластик, глина жирная;

6 — муфта

По оттиску и глубине спуска печати определяют диаметр и глубину до среза, т. е. до верха оставленной в скважине трубы. Диаметр оставленной в скважине трубы необходимо сопоставить с диаметром запроектированного скважинного насоса. Диаметр деревянного диска обычно на 5—8 мм меньше обсадной трубы, в которую опускают печать.

После монтажа насоса, установки опорной плиты на фундамент и герметизации устья скважины производят обвязку устья.

Разработан герметический оголовок для скважинных насосов с погружными электродвигателями, представленный на рис. 2. Оголовки предназначены для герметизации устья скважины, в которых предусматривается установка центробежных скважинных насосов.

Пример условного обозначения герметичного оголовка с условным проходом 150 мм конструктивного исполнения 1-ОГ-150:

Герметичный оголовок (рис. 2) состоит из устьевого патрубка 1 и опорной плиты 2, соединенных между собой при помощи болтов 3, гаек 4 и прижимных шайб 5.



Рис.2. Герметизация устья скважины

Example sentence(s):
  • For vertical turbine pumps, discharge head equals bowl head minus lift and internal pump loss. It can be shown as: hD = hB - hL - hP
  • Water Horsepower = GPM x 8.33 x Head = GPM x Head 33,000 3,960 WHERE GPM = Gallons Per Minute 8.33 = Pounds of water per gallon 33,000 = Ft. Lbs. per minute in one Hp. Head = Difference in energy head in feet (field head)
