Fire fighting integrated pump set 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 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.
large Fire fighting integrated pump set "Good, fast and economical" Talking about the advantages of prefabricated pump house, Fire fighting integrated pump set Manufacturer He said, "First of all, the quality of prefabricated concrete components is controllable, the deviation of appearance surface flatness is small, and the concrete strength of prefabricated products can reach C40, which is conducive to improving the instability of concrete quality of traditional cast-in-place structures; Secondly, the construction period is controllable. Prefabricated components are produced in factories, and on-site installation is mechanically hoisted, which is safe and convenient, and can greatly reduce the use of labor. The project duration can be free from the impact of natural weather and other factors; The third is energy conservation and environmental protection. The main body of the project is mostly prefabricated, and a large number of cement, sand and stone and other dust building materials do not need to enter the site. The construction has little impact on the surrounding urban environment. " The prefabricated steel structure building is a form of prefabricated building with high assembly rate, which covers the components of the system such as structure, enclosure, interior decoration and equipment pipeline. It is prefabricated in the factory, and the integrated module is transported to the construction site for assembly and connection to form a complete building. Fabricated steel structure buildings have the advantages of high standardization and high integration, which can greatly reduce the entire construction cycle.
1、 Fire fighting integrated pump set Manufacturer Location selection. large Fire fighting integrated pump set It is the core part of the water supply and fire fighting pipe network of the whole building or the whole community, the plant area. The location of the pump room should be selected not only to facilitate the laying of water supply and fire fighting pipe network, but also not to have noise impact on rooms with quiet requirements. It should also try to minimize the occupancy of valuable buildings (such as shops and parking spaces). The domestic water supply pump room and fire pump room should be built together, which can not only save land, but also facilitate maintenance management. For a residential area, the pump room is often designed in the equipment room of the underground garage, and is combined with the generator room and other electrical and air-conditioning rooms in the same fire compartment. And the pump room should be as close as possible to the middle of the large water users or the whole community, which can reduce the length of the main pipe and reduce the head loss of the pipe network. The outlet of the pump room shall be directly connected to the outdoor or the emergency exit. If the pump house is located in a civil building, it should not be adjacent to the neighbor's house or on its upper or lower floors, and the pump house should be located in a well ventilated room without freezing. The size of the pump room is determined by the layout of the living pool, fire pool and pump set.
large Fire fighting integrated pump set 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, Fire fighting integrated pump set Manufacturer It makes up for the shortcomings of the existing reinforced concrete operations, 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.
large Fire fighting integrated pump set Application in water supply and drainage engineering, Fire fighting integrated pump set Manufacturer Introduction! In recent years, the speed of economic development in China has risen straightly, and GDP is in a steady growth state, which shows that people's living standards are constantly improving. But for the utilization of water resources, people generally have the deep-rooted idea of inexhaustible, which leads to the increasing waste and pollution of water resources. However, at present, the development of urban industrial production has increased the utilization of water resources, so the supply of fresh water resources has presented a shortage problem. In addition, the urban industrial development has aggravated the sewage problem, and the urban sewage problem has gradually become the primary factor threatening the normal development of the city and affecting the urban ecology. Compared with the western developed countries, China's water pollution treatment technology is relatively backward. We must learn from the advanced means and technologies of water pollution treatment in western developed countries, and explore a water pollution treatment road with Chinese characteristics in combination with China's own water pollution treatment status. There may be many problems in the process of exploration, but we must continue to improve and gradually improve the efficiency of water pollution treatment. In many cases, the speed of sewage treatment in China lags far behind the speed of water pollution, while high energy consumption increases the economic load, coupled with the low degree of automation of water pollution equipment, resulting in excessive labor consumption, which will cause difficulties in water pollution treatment in China.
