The Source of Power for the Pool Water Cycle - Pool Pump

  • source:poolking;
  • Time:12/06/2018

The pool pump head is directly related to other factors such as the height of the water supply and the resistance of the pipeline. In general, the head of the circulating water pump should not be less than the geometric height of the water supply, the resistance of the equipment and piping of the circulation system, and the sum of the outflow heads multiplied by the safety factor of 1.05~1.10 as the pump head. In addition to considering the resistance of the pipeline to water, it is also necessary to consider the loss of a portion of the head due to the amount of interception of the filtration equipment after the water treatment system has been in operation for a period of time. For comprehensive consideration, it is advisable to select the circulating water pump at a multiple of 1.05~1.10.The pump head is directly related to other factors such as the height of the water supply and the resistance of the pipeline. In general, the head of the circulating water pump should not be less than the geometric height of the water supply, the resistance of the equipment and piping of the circulation system, and the sum of the outflow heads multiplied by the safety factor of 1.05~1.10 as the pump head. In addition to considering the resistance of the pipeline to water, it is also necessary to consider the loss of a portion of the head due to the amount of interception of the filtration equipment after the water treatment system has been in operation for a period of time.

Calculation method of circulating flow:

 

1). In China:

qc = (Vp·ap)/Tp

Explanation:

qc -- Circulating flow of swimming pool (m3/h)

Vp -- Swimming pool water volume (m3)

ap -- The water volume additional factor of the pipe and equipment of the swimming pool is generally 1.05~1.10.

 

2) In UK:

Circulating flow(m3/h) = Instant swimming pool load × 1.7

 

PS:The coefficient 1.7 has no theoretical basis, but it has proven to be effective in practice. However, for some swimming pools, such as diving pools and swimming pools with a water depth of more than 2.0 meters, this formula cannot be used .

 

3)In Germany:

qc = XF

Explanation:

qc -- Circulating flow of swimming pool (m3/h)

F -- Swimming pool water surface area (m2)

X -- Load factor

TYPE

Load factor (X)

USAGE

Indoor pool

0.4

Competition pool without shallow water

 

0.5

Multi-purpose swimming pool with one third of shallow water

 

0.6

Multi-purpose swimming pool with Most of shallow water

 

0.7

Public pool,school pool,training pool

Outdoor pool

0.2

 

PS: The shallow water area is an area where the swimming pool depth is 1.25 m or less for those who cannot swim.
