Swimming pool pump design requirements and usage
First, the pump use skills:
When the swimming pool pump has too much head lift, it will affect the filtration accuracy, cause human injury, overload overheating, burn out the motor, vaporize cavitation, damage the pump and piping system. It is necessary for the newly designed swimming pool and spa to consider various factors and carry out the head calculation according to the actual project. It cannot be taken for granted. For the already running system, check the pump front vacuum gauge readings and the post-pump pressure gauge to determine the actual working system head. For the major problems, do the following:
· Replace the pump and select a pump that is similar to the actual working lift and flow.
· Cut and reduce the outer diameter of the impeller to reduce the rated lift of the pump so that it is close to the actual working head of the pump
· Before the pump starts, close the valve on the water outlet pipe (the valve is located in front of the pump and tank), start the motor, thicken the bracket swimming pool wholesale, and gradually open the valve after the pump runs smoothly. By controlling the opening of the outlet valve, the pump flow is reduced, thereby reducing pump load and heat generation.
Second, the circulating water pump in the standard use precautions:
The choice of swimming pool circulating water pump should meet the following requirements:
(1) The rated flow of the pump should not be less than the calculated circulating water flow of the pool water purification treatment system to ensure the required flow rate of the pool water cycle;
(2) The lift of the pump shall not be less than the calculated value of the geometric height of the water supply, the resistance of the circulating purification treatment system equipment and the piping system, and the required outflow head of the pool inlet multiplied by 1.10;
(3) The pump should be a special frequency conversion speed regulating pump for swimming pool with high efficiency, energy-saving, corrosion resistance, and low noise;
(4) The circulating water pump of the pressure filter should not be less than 2 sets, and the standby pump should be set up and can be alternately operated with the working pump;
(5) The backwashing water pump of the quartz sand filter should be designed in parallel with the working model of the pool water circulating pump working pump and the standby pump, and adjust the circulating water pump working condition according to the flow and head check required for the backwashing of a single filter.
