PLC intelligent controlled water supply equipment with mute energy storage

Abstract

The invention provides a PLC intelligent controlled water supply equipment with mute energy storage. According to the equipment, the mode that a conventional water supply product with variable frequency and constant pressure has to be in continuous operation for 24 hours is changed, and energy storage equipment-an energy storage tank is introduced into a water supply system, so that disturbing noise in nighttime of water supply, reactive power loss of water supply and impact damage of water hammers are greatly eliminated, and the service life of the water supply equipment is prolonged. Supplementary gas of the energy storage tank is supplied by a mute oil-free gas compressor, so that the water supply efficiency of the system is improved. A submersible electric pump is sealed in a mute cover, so that the noise transmitted from the submersible electric pump to air is isolated; operation of the submersible electric pump can be stopped in quiet nights when residents sleep without using water, and when the output of water supply of the system is small, the submersible electric pump can have a long time to rest and stop, while water of the system is supplied by only the energy storage tank. The noise of the water supply equipment is greatly reduced, and the performance of energy saving, consumption reducing, environmental protecting and noise reducing of secondary water supply equipment is improved.

Description

technical field [0001] The invention relates to tap water pressurized water supply equipment, in particular to a PLC intelligently controlled silent energy storage water supply equipment. Background technique [0002] At present, most of the secondary water supply products in China are controlled by frequency conversion and constant pressure - the water pump needs to work continuously, which not only wastes energy but also consumes a lot of supporting equipment. The service life of the whole set of equipment in this water supply mode is usually not more than six years, and the maintenance burden of the equipment is also very heavy-the failure of burning motors and frequency converters occurs frequently. In the frequency conversion constant pressure secondary water supply system, the water hammer problem is also difficult to eliminate. The higher the water supply floor, the more serious the water hammer phenomenon. The leakage of underground pipe network caused by water ham...
