1. Matching of filter sand cylinder and water pump power
It should be emphasized that the flow parameters of the sand filter cylinder are actually of little reference value. Because the actual filtration capacity of the filter sand tank is related to the flow rate of the water pump, the amount of sand loaded in the sand tank, and the thickness of the sand particles. And just during the working process of the sand filter cylinder, there is also a flow change from large to small. Therefore, strictly speaking, the sand filter cylinder does not have the parameter of flow rate. The greater the flow rate of the water pump in front of it, the greater its water flow; the smaller its sand loading, the greater the water flow; the coarser the sand, the greater the water flow. Under the same water flow requirements, the filter sand The configuration of the cylinder is the bigger the better, the finer the sand, the higher the precision.
2. The difference between the top outlet sand filter cylinder and the side outlet sand filter cylinder
In fact, there is no difference in their internal structure, and their functions are the same. The only difference is the position of the sand tank head. Because the installation space of some customers is relatively low, only the side-out sand filter tank is suitable, or because the side-out sand filter tank is more convenient for manual operation, it is relatively convenient to change the sand; and the ejector sand filter tank is due to mold development and other reasons. , the price is relatively low, so customers generally choose to push out the filter sand cylinder.
3. The location of the water pump
Except for self-priming pumps sold on the market, general centrifugal water pumps have no suction lift in theory. When installing, the position of the water pump should be lower than at least not higher than the water level of the treated water.
4, the flatness of the ground between the equipment
After the sand tank is filled with sand, the overall weight is very large, and at this time, the ground where the sand tank is placed must be kept at a certain level. Because the base of the filter sand cylinder is designed on a very flat ground, if the ground between the equipment is uneven after installation, it will cause deformation of the filter sand base.
5. Antifreeze in winter
When the sand filter tank is not in use in winter, all the water in it should be drained through the drain valve at the lower part, so as to prevent the water from freezing and expanding in the tank and bursting the sand tank body.
