[Asia Pump Network News] pipeline booster pump, as its name implies, is installed in the pipeline booster pump. Because of its simple and compact structure, small size, light weight, wide range of performance, easy operation and so on, has now been widely used in daily production and life, plays an important role. However, the face dazzling array of the market, types and types of pneumatic diaphragm pumps, consumers often choose the type of pipeline booster pump painstakingly, can not start. Xiaobian current interpretation for you one by one. Pipeline booster pump selection principles and steps A list of basic data: 1, the characteristics of the media: media name, specific gravity, viscosity, corrosion, toxicity and so on. 2, the medium contained in the solid particle diameter, content how much. 3, the medium temperature: (℃) 4, the required flow General industrial pumps in the process can be ignored in the pipeline leakage, but must consider the impact of process changes on the flow. Agricultural pumps if the use of open channel water, but also must consider the leakage and evaporation. 5, pressure: suction tank pressure, drainage tank pressure, pressure difference in the piping system (head loss). 6, the piping system data (diameter, length, type and number of pipe fittings, water tank to the pressure tank geometric elevation, etc.). The device characteristics should also be made if necessary. In the design and layout of the pipeline, should pay attention to the following: A, a reasonable choice of pipe diameter, pipe diameter, the same flow, the flow velocity is small, the resistance loss is small, but the price is high, the pipe diameter is small, will lead to a sharp increase in resistance loss Large, so that the selected pump lift, with increased power costs and operating costs have increased. Therefore, it should be considered technically and economically. B, discharge pipe and its fittings should consider the maximum pressure that can bear. C, pipe layout should be arranged as straight pipe, pipe fittings to minimize and minimize the length of the pipeline, you must turn when bending the elbow bend radius should be 3 to 5 times the pipe diameter, the angle is greater than 90 ℃. D, the discharge side of the pump must be installed valves (ball valve or globe valve, etc.) and check valve. The valve is used to adjust the operating conditions of the pump. The check valve prevents the pump from reversing when the fluid is flowing backwards and prevents the pump from hitting the water hammer. (When the liquid backflow, will have a huge reverse pressure, so that the pump damage) Second, to determine the flow head of the flow to determine a, if the production process has been given the smallest, normal, maximum flow, should be considered the maximum flow. b, if the production process is only given normal flow, should consider leaving a certain margin. For ns> 100 large flow low lift pump, take 5% of flow margin, for ns c, if the basic data only to the weight flow, should be converted into volume flow Above is the basic principle of selection of the pipeline booster pump and steps, of course, specific Specific analysis of the situation, consumers should take the appropriate method of purchase according to the actual situation, so as to "Amoy" favorite pipeline booster pump.
