recommend Pressure vessel Application in water supply and drainage engineering, Pressure vessel Price 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.

Users also have this problem again. First of all, we should know the composition of the pump station. ad locum, Pressure vessel Price 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. recommend Pressure vessel 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, 300 refers to the flow of 300m ³/h, 7 refers to the head of 7m, and 15 refers to the power of this submersible pump of 15KW.

recommend Pressure vessel 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. Pressure vessel Price 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.

recommend Pressure vessel What are the requirements for backfilling after installation? 1. Before backfilling, check that the pump station has not suffered structural damage. If yes, please contact our company as soon as possible and do not dispose of it by yourself! 2. After completing the installation and grouting of the pump station on the cement base plate and reaching the required strength, check that the structure is intact, and then backfill can be carried out. three Pressure vessel Price Backfilling must be carried out in time after installation to prevent the pump station from floating and toppling, and the FRP material cannot be pulled or squeezed by force. 4.32mm plain soil can also be backfilled with graded sand and gravel, and the particle size of gravel shall not exceed 32mm. When the distance between the pump station barrel and the edge of the foundation pit is less than 1 m but more than 0.5 m, only graded sand and gravel can be used for backfilling, and the gravel particle size shall not exceed 32 mm. When backfilling in winter and rainy days, check whether the backfill materials are stuck together. The backfilling of the foundation pit shall be carried out continuously and completed as soon as possible. During the construction, the ground water shall be prevented from flowing into the foundation pit to avoid slope collapse or damage to the foundation soil. Backfilling shall be carried out in layers. The height difference of each layer shall not exceed 50cm. It shall be compacted with a tamper or manually, and the compaction shall be more than 90%.
