Shizuishan villa swimming pool filter sand tank swimming pool self-priming centrifugal pump swimming pool water disinfection equipment

Shizuishan villa swimming pool filter sand tank swimming pool self-priming centrifugal pump swimming pool water disinfection equipment heat exchange plate and sealing pad are the same, the four flow channel holes on the plate are the same size, the same medium in the two flow channels on one side The entrance and exit of the holes, as shown in the figure, cannot form a diagonal flow pattern. During assembly, the adjacent heat exchange plates are turned d so that the herringbone direction is opposite. After assembly, the cross-sectional flow areas of the two flow channels are the same. The characteristic of type B is that it uses two different heat exchange plates and rubber pads (commonly known as plate pads and B plate and B pads). There are two large flow channel holes in the diagonal direction of the plate, and two small flow channel holes in the diagonal direction. The same medium enters and exits through the diagonal flow channel holes, but cannot enter and exit the same side flow channel holes, as shown in the figure. The corrugated cross-section shapes of the two plates are also different. During assembly, the two plates are stacked alternately. After assembly, because the corrugated cross-sections of the two plates are opposite to each other, the corrugated inner cavity of the plate corresponding to the large flow hole forms a large flow. The corrugated inner cavity of the plate corresponding to the small flow channel hole forms a small flow channel cross section. This is the origin of the B-type unequal flow channel cross section. The ratio of the two cross-sectional areas is roughly:. When the flow rates of the two media are different and Roughly: This type of heat exchanger can be selected when it is difficult to assemble into a dual process. It is suitable for centralized heating in residential areas. Generally, the flow of hot water in the primary network is small and the flow of heating and water supply for users in the secondary network is large.
This type of heat exchanger can be selected when the flow rates of the two media are different and roughly: and it is not easy to assemble into a double process. It is suitable for centralized heating in residential areas. Generally, the flow of hot water in the primary network is small and the flow of heating and water supply for users in the secondary network is large. The characteristic of this type is that the shape of the heat exchange plate is symmetrical in the center and there are two sets of sealing pads, which can enable the plate heat exchanger to achieve unilateral flow or diagonal flow. R-type plate heat exchangers are divided into BR., BR., BR., BR., BR., BR., BR., BR., BR., BR., BR., BR., BR., BR from small to large. ., BR.R., BR. type plate heat exchangers are divided into B., B., B., B., B., B., B., B. from small to large. BR type plate heat exchangers are divided into BR., BR., BR., BR., BR., BR., BR., BR., BR. from small to large. BR. refers to the effective heat exchange area of a single heat exchange plate. square meters, other models have the same meaning. Select a certain model and use different numbers of heat exchange plates to assemble a heat exchanger with the required heat exchange area.
