recommend Mobile machine room 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. Mobile machine room 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 Mobile machine room 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 Mobile machine room 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%.

Mobile machine room Price This paper introduces the advantages of the assembled steel structure building: 1. Standardization: standardization is the basis of modular construction. The standardization of module geometric size, connection mode, module combination form, internal parts, equipment and facilities is the basic guarantee to realize rapid and high-quality construction. 2. Modularization: all functional spaces are composed of modules with a high degree of standardization, which fully reflects the speed advantages brought by standardization and integration and meets the needs of emergency medical facilities construction. 3. Industrialization: the construction will be completed in a short time, and the designer will make full use of the existing module product size. While processing the floor on site, modules are produced synchronously in the factory. The factory environment and indoor construction conditions will ensure that its quality is easier to control and improve, defects are reduced, product reliability is improved, and production efficiency is high. 4. Assembling: the construction period on site is very short. In addition to wet operations such as floor leveling and foundation treatment, other parts of the site, such as equipment pipeline installation, door and window installation, indoor facilities installation, etc., are completely dry construction. Different types of work cross each other. Compared with traditional construction methods, it saves time, recommend Mobile machine room Construction and decoration waste will also be reduced by about 70%.

recommend Mobile machine room How to choose? Mobile machine room Price 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.

recommend Mobile machine room Application in water supply and drainage engineering, Mobile machine room 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.

1、 Mobile machine room Price Location selection. recommend Mobile machine room 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.
