Description

High-efficiency energy-saving water-absorbing water supply device

Technical Field

The invention relates to the field of water supply of underground swirl wells, water absorption pools and the like in steel, chemical engineering, oil refining, urban tap water and the like, in particular to a high-efficiency energy-saving water absorption and supply device.

Background

In water supply, water use and water return systems for production in industries such as steel, chemical engineering, oil refining, urban tap water and the like, underground cyclone wells are used for treating turbid circulating water or urban tap water companies supply clean water through underground water tanks. Particularly, a swirling well is used in the steel industry to treat turbid circulating water, the swirling well is located more than 10 meters underground, a used sealless self-priming pump is 2 meters away from the liquid level at the upper part of the swirling well, clean water is filled in a pump cavity when the pump is started, air in a water suction pipeline is extracted by the clean water in the pump cavity in a self-circulation mode after the pump is started, and then a water pump outlet valve is opened to supply water, so that the situation that the environment is influenced by water flowing out from a pump shaft gap in the pump cavity and a motor bearing is damaged by water inflow is avoided, therefore, an auxiliary impeller is arranged on the pump shaft in the pump cavity to suppress water flowing out from the pump shaft gap, more electric energy is consumed, the mechanical efficiency of the water pump is only about 50-55%, the clean water is refilled due to the fact that vacuum is broken when the pump is stopped every time, the starting time is long, the workload of workers is large, the water pump is unreliable in operation, and the like.

In recent years, in order to solve the problem of low efficiency of a non-sealing self-priming pump, a part of energy-saving companies install vacuum pumps on an inlet pipeline and a pump cavity of a water pump, when the energy-saving self-priming pump is started, air in the water suction pipeline and the pump cavity is pumped out by the vacuum pumps, a vacuum water suction state is established, then the water pump is started to work, the efficiency of the water pump reaches 85% -90%, and a good energy-saving effect is achieved. However, the unfavorable conditions that the time for pumping vacuum is long due to the fact that the pipeline or the valve of the water pump is not closed tightly or the time is delayed due to the fact that the reason is found again due to the fact that the vacuum pumping is failed exist, and therefore the safe, efficient and energy-saving water absorption and supply device is needed to solve the problems.
