Application of submersible electric pump in emergency drainage
Using water pumps to quickly drain water from low-lying and flood-prone areas is one of the effective measures to reduce waterlogging after the flood. In recent years, the use of submersible electric pumps to relieve sudden flood disasters in extraordinary periods is receiving special attention from all walks of life. It is understood. Japan has developed a complete set of mobile special emergency drainage submersible pumps for the main purpose of eliminating waterlogging in smaller rivers. What followed was the emergence of emergency drainage, and technical standards for emergency drainage pump equipment were also compiled.
1. Features of emergency drainage
The so-called emergency drainage refers to the emergency drainage task that comes in an emergency. Such as: flash floods are critical to the safety of mines and foundation pits, to stabilize the soil and prevent landslides and other emergency drainage when accidents occur; when typhoons and rainstorms strike, to protect low-lying flood-prone areas from waterlogging disasters and so on. Compared with general drainage tasks, the characteristics of emergency drainage are:
(1) The task is urgent Emergency drainage is always accompanied by sudden disasters, and it is often impossible to make preparations in advance. At the same time, if the emergency drainage measures are not implemented well, the consequences will be unimaginable. Therefore, “emergency drainage” is also called “emergency drainage”.
(2) The standard is high. The design standard of general drainage pumping station is designed to drain to the depth of the crop tolerant of flooding in 1 to 3 days of heavy rain per day, while emergency drainage usually requires the flooding and accumulation of water caused by excessive heavy rain to be exhausted. It may be eliminated in a short period of time, far exceeding the design standards of general drainage pumping stations
(3) When sudden disasters such as severe typhoons and rainstorms come, power outages are accompanied by violent storms, which invisibly aggravates the difficulty of rushing to discharge at night, and often requires emergency drainage to adapt to an unpowered power supply. 2. Bad working conditions with ignorant lighting conditions and wind and rain.
2. Application of submersible electric pump in emergency drainage
In order to meet the needs of emergency drainage, it is necessary to develop a complete set of equipment with the following conditions.
(1) Movable and use movable devices, so that when necessary, multiple standby water pump units can be used to centrally solve the urgent and high-standard emergency drainage tasks; or the emergency water special equipment should be kept in a centralized manner, and the emergency drainage equipment management center or emergency The drainage base can be called at any time as needed.
(2) Ease of loading and unloading The pump unit requires compact structure, easy operation, reliable work, and requires small size, light weight, simple and convenient removal and loading and unloading.
(3) Strong versatility Water pump units require strong versatility. The installation dimensions of products produced by any manufacturer are the same, and the parts and components should be interchangeable at will, so as to shorten the installation time on site and facilitate equipment matching and maintenance management.
The main features of this equipment are as follows:
(1) Flexible and fast response speed. Go where you need it, and change from passive waiting to active attack, which is convenient for coping with emergencies in flood fighting and disaster relief;
(2) Strong adaptability, no need to support any hydraulic structures, the outlet pipe is a hose, the site can be selected at will, and it can work normally in places without power;
(3) Project investment province. Because of the cancellation of complex hydraulic structures, the project cost has been greatly reduced;
(4) Easy to manage. Mobile irrigation and drainage trucks can be managed centrally, which completely changes the situation that the original irrigation and drainage equipment is placed in the wilderness and is easily damaged by man-made and natural factors, which is conducive to the improvement of the management level of small and medium-sized electromechanical irrigation and drainage equipment.
(5) High utilization rate of equipment The equipment can be used for emergency drainage and irrigation. When there is no irrigation and no drainage tasks, the lifting equipment can also be used for technical transformation of pumping stations, construction drainage of large projects, etc.
