Users also have this problem again. First of all, we should know the composition of the pump station. ad locum, Fire fighting integrated pump set manufactor The pump set is divided into three parts. Main body of pump unit, external control equipment and internal equipment. First, we should select the wall thickness of the pump unit cylinder according to the actual demand. The factors to be considered here include: geology, temperature, working environment of pump unit, altitude, etc. Therefore, the selection of pump unit cylinder wall thickness should be summarized and considered. The wall thickness directly affects the firmness of the pump set. Of course, the selection of internal equipment is also important. During this period, the selection of submersible sewage pump is important. Here, the selection of flow head of submersible sewage pump is important. supply Fire fighting integrated pump set The flow head of submersible sewage pump shall be selected according to the actual situation. There are many types of submersible sewage pumps. For example, 200 in front of 200WQ300-7-15 refers to the diameter, WQ refers to the pump type, and 300 refers to the flow of 300m ³/ h. 7 refers to the lift of 7m, and 15 refers to the power of this submersible pump of 15KW.
Fire fighting integrated pump set manufactor The design principle is: (1) The overall layout should be reasonable, especially for the pump stations that combine irrigation and drainage or self drainage, self diversion and water lifting, as well as the pump stations that combine gates and stations, the layout should be as compact as possible, making full use of buildings for regulation. (2) The selection of pump type shall strive to make the design head of the pump station consistent with the rated head of the pump, and meet the requirements of irrigation and drainage flow. The pump type with advanced technology shall be selected as far as possible to ensure high efficiency of the pump station device and low operation cost. At the same time, the selected pump type should be relatively mature, with certain operation practice, and the test pump type should be avoided as far as possible. (3) The selection of pump type shall fully consider the use and working nature of the integrated pump station. For irrigation and make-up water pump stations with long annual working hours, pumps with wide range, high efficiency and good cavitation performance shall be selected. For those pumping stations focusing on drainage, the pump type with reliable working performance and simple structure shall be selected. (4) The project layout shall adopt positive water inflow as far as possible to ensure that the water inflow condition of each unit is good and the flow pattern is uniform. supply Fire fighting integrated pump set When lateral water inflow has to be adopted in the project layout, the distance between the lateral water inlet and the pump shall be extended as far as possible in the design, and certain diversion measures shall be taken. (5) The design of the outlet pool should try to avoid sharp bends that cause water impact and backwater. The pressure water tank shall be designed to avoid the increase of energy loss due to the mutual impact of water flow in each outlet pipe. (6) The construction materials available locally shall be used as far as possible. The design shall ensure simple and convenient construction and less project investment.
supply Fire fighting integrated pump set How to choose? Fire fighting integrated pump set manufactor The main equipment in the pump station selected according to the input and output are: various controllable valves, pump sets, grid systems, water level gauges, flow meters, etc. According to the requirements of the system and the different control methods adopted, as well as the nature, parameters and characteristics of the input and output signals, the appropriate PLC system can be flexibly selected. Select according to the storage capacity Calculate the actual capacity demand of the storage according to the number of nodes required for programming. The PLC control system used in the current pump station is selected according to the communication requirements, which is generally divided into equipment unit layer, pump station layer, dispatching layer, etc. Layers directly need to transmit various parameter information, so we should select the appropriate PLC equipment according to the field needs, such as network, expansion, off the shelf bus connection, investment and our own equipment.
1. To ensure the safety of the pump room, the pump room must be locked. 2、 Fire fighting integrated pump set manufactor Safety Operation Regulations, Hygiene and Safety Management System for Secondary Water Supply, Patrol Inspection Specifications, Water Quality Inspection Record System must be posted inside. 3 supply Fire fighting integrated pump set The following record files must be available inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must have a pressurized area mark, and the corresponding control system should also have a pressurized area mark: low area, middle area, high area, etc, Mark the product model, qualified number, ex factory date, etc. 6. Water pump identification: the number of pumps must be painted on each pump; For example: 1 # pump, 2 # pump, 3 # pump, 4 # pump, 5 # pump, words. 7. "Normally open" signboard of inlet and outlet valves; 8. The pipe shall be marked with water flow direction arrow; 9. The prefabricated energy-saving pump room needs a drainage system 10. The energy-saving pump room can realize on-site control and remote monitoring;
