Several problems should be paid attention to in the combined use of filter sand cylinder and water pump

2023/03/28

The filter sand tank and the water pump are inseparable brothers in normal water treatment projects. They can be seen in many industries such as swimming pool engineering, circulating aquaculture engineering, flowing water aquaculture engineering, environmental protection water treatment, urban sewage treatment, drinking water treatment, etc. However, according to Boying Water Equipment's many years of sales experience, when customers configure sand filter tanks and water pumps, there will be a little problem.

We conduct some necessary analysis on these minor issues. 1. Match the power of the sand filter tank with the water pump. 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 configuration of the filter sand tank 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. The functions are the same, the only difference is the location of the sand tank head. Due to the low installation space of some customers, only the side-out type sand filter tank is suitable.

Or because the side-out filter sand tank is more convenient for manual operation. However, due to mold development and other reasons, the price of the ejector filter sand cylinder is relatively low. This makes customers generally choose to eject the sand filter cylinder.

3. The location of the water pump. In addition to 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 in the equipment room. 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 filter sand tank is not in use in winter, all the water in it should be drained through the lower drain valve.

In order to prevent the water from freezing and expanding in the cylinder body and bursting the cylinder body of the sand cylinder.
