Water tower constant pressure water supplying system and method with alternately working water pumps

Abstract

The invention discloses a water tower constant pressure water supplying system and method with alternately working water pumps. The system comprises a water storage tank arranged on the water tower, awater level detecting module is arranged in the water storage box, the water storage box is even number of water pumps which can independently operate, and the water pumps and the water level detecting module are connected with a controller. According to the system, the working time of each water pump is recorded by the controller, the working time of the water pump is accumulated, the water pumpwith short accumulated operating time is operated by the controller in the first place, so that the difference between the operation times of the water pumps is not large, the constant working time and intensity of each water pump are reduced, the constant operation time of each water pump is controlled to be half an hour or less, the normal stopping time is hour an hour or above, so that the constant operation intensity of the water pumps is well reduced to help to prolong the actual service life of the water pumps.

Description

technical field [0001] The invention relates to the technical field of water tower constant pressure water supply, in particular to a water tower constant pressure water supply system and method in which multiple water pumps work alternately. Background technique [0002] Water towers are used to store water in general residential areas, and some are an important part of the production process of water plants. They are towering structures used for water storage and distribution, and are used to maintain and adjust the water volume and water pressure in the water supply network. The development of the country and the demand for water have put forward higher requirements for water supply. It is necessary to meet the timely, sufficient pressure, and water supply with a certain water storage capacity. The water level of the water tower is high, resulting in high pressure, and the water tower has a certain water storage capacity. Even if there is an emergency water stop or pipeli...

Problems solved by technology

[0005] Although this kind of constant pressure water supply device is a constant pressure water supply device, the residential water is provided by the water supply tower. When the water consumption is relatively large, the water level in the water supply tower will drop, which will be detected by the liquid level sensor. Ascent, the openings of the inlet pipe and the outlet pipe are designed to be relatively wide and relatively large, so that the supply tower can quickly replenish the water in the water supply tower, maintain the water level, ensure the water pressure, and make the water pressure constant and stable, but cannot reduce the water supply. The continuous running time of the water pump for the water supply of the water tower, the continuous operation of the water pump for a long time will lead to high work intensity, easy mechanical fatigue, and cause failure. This kind of water supply device is not designed to increase the water supply during the peak period of water consumption, so it cannot guarantee the water storage capacity of the water tower, so it cannot guarantee constant pressure water supply, which may lead to low water supply pressure or even water shortage
