vertical pipeline chemical pump is used for conveying clean water and other liquids with similar physical and chemical properties to clean water. The hot and cold water circulation pressurization and equipment matching in the bathroom, etc., are common procedures for the selection of pipeline pumps. details as follows:
1. Identify the current water supply situation on site
If it is industrial water supply, it does not matter the municipal water supply; if it is a residential building water supply, it is very important to first determine your on-site municipal water supply, because we need to know whether you are suitable for direct supply or water storage in a pool and then water supply again. On-site conditions that need to be known: the size of the municipal water supply pipe, the current water pressure value (the floor height that the water can press), whether the municipal water supply is stable, etc.
2. Determine the larger flow rate Q required by the vertical pipeline chemical pump
The flow rate is the larger unit volume that needs to be conveyed per hour, generally ton/hour or liter/minute. When determining the flow, budget according to the larger possible flow, otherwise there may be insufficient flow. For industrial production pressurization, the flow value must be provided by the user, because there is no standard industrial flow calculation formula; ordinary experienced people with domestic water use can roughly estimate the maximum water consumption per hour. If they do not have any industry experience, The best way for you to calculate the flow is to let us assist in the calculation, but we need to understand several important parameters to determine the water equivalent: such as the number of households, the number of hotel rooms, the amount of toilets, the amount of squat toilets, the number of baths, etc. After determining the corresponding amount of water consumption, the larger rated flow we need can be calculated according to the flow calculation formula Q={[amount of water consumption of corresponding nature × water equivalent of corresponding nature] ÷ total water consumption time} × hourly variation coefficient.
3. Determine the higher head or higher pressure required by the vertical pipeline chemical pump
First of all, a concept is clarified, that is, the pump head and the pressure generated by the pump can be converted to each other according to the fixed feed rate. 1Pa=10kgf/cm? (often said 10kg pressure) = 10kg force/cm? (often said 10kg pressure) = 100 meters of lift. How much pressure is needed can be directly selected according to the corresponding head to generate the corresponding pressure.
If the flow is enough, it is useless if the head or pressure is not enough. For industrial water, the user must propose the required pressure value, because no professional company can cover the industrial water pressure of the whole industry; while the water supply for residential buildings is different, it can be calculated according to the existing conditions provided by the user, we need Know the total height of the floor, the floor height that the current municipal water can reach, the total length of the pipe network and the number of right-angle elbows, etc. After determining these conditions, we can accurately calculate the head. The general formula for calculating the head of a pipeline pump is H = total number of floors × height of a single floor + loss of 5 meters per 100 meters of horizontal pipes + loss of 1 meter per right angle elbow. . For example, if you calculate the total lift of 100 meters according to this formula, and the current water can reach a height of 20 meters, then you only need to choose a lift of 80 meters for direct water supply.
Fourth, determine the type of vertical pipeline chemical pump selection
In some occasions, horizontal pumps may be better. For example, in general industrial production, more horizontal single-stage pumps are used. Horizontal pumps are generally small in height, large in flow, and relatively low in lift;
At present, the water supply in the construction field is basically replaced by stainless steel vertical pumps, mainly due to the influence of parameters such as efficiency, sanitation and head.
If you need small flow and low head, choose horizontal single-stage or multi-stage stainless steel products.
Vertical multi-stage centrifugal pumps are preferred for high-lift series products.
Vertical single-stage pipeline centrifugal pump with large flow and low lift.
Of course, the determination of the type of pump requires a certain amount of experience.
