Pipeline centrifugal pump classification and product use: Reasonable selection of pumps and pump units should also take into account technical indicators so that they are in line with economic principles and safe to use. Specifically include the following: 1) Pumps with high efficiency, low noise, and energy saving water should be selected, and outdated products are strictly prohibited. 2) According to the design flow, there are many reasons for the need for a lift pump to generate the pump. Among them, it is recognized that due to the output of the wear pump, the flow characteristic curve may be increased according to the head of the pump. Because this can make the water pump down, make the water pump work more stable and reliable, but also to keep the pump work point in the range of effective operation, in order to produce energy-saving and not easily damaged results. 3) When there is no adjustment of water supply pipe network facilities, it is advisable to use the best grouping operation water supply. The largest pump group should not be lower than a village in the water supply design process. 4) Select the water tank, water tower lift pump should be minimized pump set, should be used in use, when the single pump can meet the demand, it should use more than one set of parallel, if you must use more than a pair of parallel operation or pump size, model If there are too many quantities and more than two models, the pump lift range will be closed. 5) The design flow of the variable frequency speed control pump (group) should ensure the satisfaction of the second largest design flow of drinking water systems. There must be a reliable power supply (dual power supply or dual circuit power supply). The personnel at the pump operating point should be in the efficient working area of ​​the pump characteristic curve (Q-H curve) and cannot be selected in the Q-H curve, the most unfavorable expansion The design of the work should be in the effective part of the right end of the characteristic curve of the pump. The maximum water pump output, the low head, and the requirement to meet this requirement are also the intersection points of the inefficient pump characteristic curve area and the pipe characteristic curve. It is possible to control the working range of the pump as much as possible within the valid period and the water supply of the pump between the appropriate speed range. The equipment should have the water level automatic control function. 6) The pump motor voltage should be the same, and the power system should be the same as the national grid power system. Improve pump efficiency Pump energy saving and consumption reduction should be continuously explored, constantly citing new technologies and finding a more reasonable and economical energy-saving measure. In the process of the pump, under the action of the pump flow rate of the water flow and the viscosity of the surface of the pump impeller, the consumed energy pump is mainly used for surface frictional resistance metering and eddy current resistance of the water. If the surface of the pump or impeller is smooth, the surface is called a hydraulic smooth surface, the surface resistance is small, and the energy consumption is small. Product use 1. Pipeline centrifugal pump , pipeline centrifugal pump is used when transporting liquids. It is suitable for use in construction equipments, residential gardens, and water heaters for cold water heaters. The temperature is less than or equal to 80 degrees Celsius. 2, (high temperature) hot water circulation pump widely used. 3, horizontal pump to transport petroleum products, such as gasoline, diesel, kerosene and so on.
