Ordinary vertical centrifugal pump Manufacturer 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. large Ordinary vertical centrifugal pump 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.
large Ordinary vertical centrifugal pump There were few original cast-in-place operations on the site, and the health did not disturb the residents. From then on, we bid farewell to the "gray and hazy" construction site. In addition, the reuse rate of steel formwork and other materials has been improved, and the waste, loss and energy saving can be reduced by more than half. It can be seen that, Ordinary vertical centrifugal pump Manufacturer It makes up for the shortcomings of the existing reinforced concrete operation, and the quality of the houses is also very good, which is acceptable to the public. Think about the future when prefabricated housing becomes the main construction industry in China, there will be no more dust flying around the construction site and no more construction waste everywhere. At present, the environment in our country is getting worse and worse. It can be seen that the energy-saving pump room is not only good, but also very promising.
1. To ensure the safety of the pump room, the pump room must be locked. 2、 Ordinary vertical centrifugal pump Manufacturer 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 large Ordinary vertical centrifugal pump 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;
Ordinary vertical centrifugal pump Manufacturer The integrated prefabricated pump station is a comprehensive urban drainage and water supply device that provides potential energy and pressure energy for water. It is composed of cylinders, pipelines, electromechanical equipment, electrical control and other ancillary facilities, and is scientifically matched, reasonably designed and assembled. Its drainage performance, safety performance and operation reliability directly determine the safety of urban drainage and water supply. large Ordinary vertical centrifugal pump The demander's requirements for its performance are also getting higher and higher, so detection is the way to obtain the demander's approval.
