Deep well submersible pump used for water drainage in emergency
One of the effective measures to reduce water logging and stagnant water in low lying places after severe flood is to drain that water quickly with the help of water pumps. In recent years, using submersible electric water pump to deal with sudden flood disaster in special periods is catching attention from people from all relevant walks of life. It is known that Japan has made research to develop a complete set of special mobile submersible drainage pumping unit for emergency in smaller scale rivers and streams to eliminate water logging. They also compiled emergency water drainage pumping equipment technical standards. Besides, in 1995, Shenyang city in Liaoning province in China started to make research about mobile drainage and irrigation vehicle equipped with deep well submersible pump, and played an important role in fighting against flooding disaster from the river of Liao in the same year.
1. Emergency water drainage features
Deep well submersible pump can be used in emergency for water pumps. Emergency water drainage refers to a sudden task of water drainage in special times for rescue. For example, water drainage for emergency in cases of flash flood, risky mines; or for foundation pit safety, stabilizing the soil base, and preventing landslide; or for protecting low lying places from water logging, etc. Compared with common tasks of water drainage, water drainage in emergency has the following features:
1) Hurry and urgent
Emergency water drainage often comes along with sudden disastrous weather. It is usually impossible for people to make preparation ahead. Meanwhile, if we cannot take effective measures to drain water in emergency, the consequences will be beyond our imagination. Therefore, water drainage in emergency is also called water drainage for rescue.
2) High standard
Generally, flood drainage pumping stations are designed according to the standard that rainwater accumulated in one day should be drained to the level tolerable for crops in 1~3 days. But emergency water drainage often requires that water logging and stagnant water caused by extra big rainstorms should be drained as quickly as possible
