Embodiment 1

[0020] Such as figure 1 As shown, an energized protection pressure tank includes a pressure tank 10, a water pump 20 and an intelligent control module 30; the pressure tank 10 is provided with a water inlet 11 and a water outlet 12, and the water outlet of the water pump 20 and the pressure tank 10 The water inlet 11 is connected; such as figure 2 As shown, the intelligent control module 30 includes a microcontroller 31, the pressure tank 10 is provided with a first pressure sensor 16 for detecting the pressure in the tank, and the impeller cavity of the water pump 20 is provided for detecting the pressure in the impeller chamber. The second pressure sensor 22 for pressure, the first pressure sensor 16 and the second pressure sensor 22 are respectively electrically connected to the signal input end of the microcontroller 31, and the signal output end of the microcontroller 31 is driven by the power of the water pump 20 The module 21 is electrically connected; the intelligent c...

Embodiment 2

[0030] A method for controlling the pressure tank 10 to be energized and protected:

[0031] When the first pressure sensor 16 detects that the pressure in the pressure tank 10 is less than the preset minimum pressure, the microcontroller 31 sends a control signal to the power drive module 21 of the water pump 20 to start the water pump 20; when the first pressure sensor 16 detects When the pressure in the pressure tank 10 is greater than the preset maximum pressure, the microcontroller 31 sends a control signal to the power driving module 21 of the water pump 20 to stop the water pump 20 from running.

[0032] When the microcontroller 31 detects that the water pump 20 has stopped running for more than 48 hours through the second pressure sensor 22, the microcontroller 31 sends a pulse signal to the power drive module 21 of the water pump 20 to rotate the water pump 20 to a certain angle to prevent the water pump 20 from being too long. Time stands still and causes rust.

Abstract

The invention belongs to water supply equipment and specifically relates to a power-on protective pressure tank and a control method for the same. The power-on protective pressure tank comprises a pressure tank, a water pump and an intelligent control module, wherein the intelligent control module comprises a micro controller; a first pressure sensor used to detect the pressure in the tank is disposed on the pressure tank; a second pressure sensor used to detect the pressure inside an impeller chamber is disposed on the impeller chamber of the water pump; the first pressure sensor and the second pressure sensor are electrically connected to a signal input end of the micro controller respectively, and a signal output end of the micro controller is electrically connected to a power drive module of the water pump; the intelligent control module and the power drive module of the water pump are electrically connected to a power source; and the micro controller is also connected to a storage unit. According to the invention, the intelligent control module controls switching-on and switching-off of the water pump according to running parameters of the pressure tank and the water pump collected by each sensor. In this way, problems such as water pump rust, water pressure unevenness, easy burning of electric appliances and water pump idling can be avoided effectively.

Description

Technical field [0001] The invention belongs to water supply equipment, and specifically relates to an energized protection pressure tank and a control method thereof. Background technique [0002] The pressure tank is a high-pressure water supply equipment used in conjunction with a water pump. The water pump injects water into the pressure tank, and the pressure tank pressurizes the water and outputs it outwards. Nowadays, with the improvement of rural living standards, pressure tanks have gradually entered the civilian field, so the requirements for miniaturization and integration of their structures are getting higher and higher. The traditional pressure tank has the following defects: 1. When the pressure tank control system is energized, the instantaneous intervention of the current will cause a certain burden on the electronic components, and it is easy to burn the controller; 2. When the pressure tank is not used for a long time, the water pump is easy to generate Rust; ...
