recommend Ordinary horizontal centrifugal pump Look at the trend of future architectural situation? Ordinary horizontal centrifugal pump manufactor Let's talk about it: the house is a place for people to shelter from wind and rain at the beginning, but with the development of society and the improvement of living standards, people continue to pursue a comfortable living environment. While improving the construction level, they install various heating and cooling equipment to solve the problem of heating and cooling, and install fresh air and humidity control equipment to solve the problem of indoor ventilation and humidity. At present, the comfort of the house has reached the standard of constant temperature, humidity, oxygen and cleanliness. However, the energy consumption of buildings has been increasing, accounting for 30-40% of the total energy consumption of the society, resulting in an energy crisis, and the environment is getting worse and worse, which seriously affects the sustainable development of society. How can we not only meet the requirements of living comfort today, but also fundamentally reduce energy consumption? This is a subject that has been studied all over the world.

We often hear that pump stations have many uses, and are dazzled by various articles. It seems that the more we understand them, the more difficult it is to understand them. Then we will talk about some introductions of pump stations and what they can do. First of all, the pump station looks ordinary to us. Its exterior is dark green glass fiber reinforced plastic cylinder, which seems very simple, but it is not. In fact, the internal structure of the pump station can be very complex and diverse. In the dark green shell of the integrated pump station, there are many parts and components. The core of the pump station we are talking about is the water pump. For pump stations of some sizes, there is not only one water pump, but basically all of them are from the water pump unit. As for the model selection of the pump, the previous articles have also talked about it, so I will not say much here.

recommend Ordinary horizontal centrifugal pump Application in water supply and drainage engineering, Ordinary horizontal centrifugal pump manufactor 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.

Ordinary horizontal centrifugal pump 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. recommend Ordinary horizontal 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.

recommend Ordinary horizontal centrifugal pump In the design, there is no such statement as main pump and standby pump. Our statement is that one is in use and one is standby or two is in use and one is standby. They are standby for each other and used in turn. When one is running, the other is the standby pump. Ordinary horizontal centrifugal pump manufactor The first reason for setting a standby pump is to ensure that when the pump is damaged or overhauled, there is still a pump that can work, rather than that we can't use water as long as the pump is broken or regularly overhauled. The second is to let the pump take turns to rest after working for a period of time. To prevent long-term continuous operation from affecting the normal service life of the pump.
