Embodiment Construction

[0032] Such as figure 1 , The low water level detector and the high water level detector are placed in the upper pool, each of them is provided with a hollow tube, the lower end openings are respectively set at the low and high water level lines, and the upper ends are respectively equipped with pneumatic switches K1 and K2. In the circuit, the pneumatic switches K1 and K2 are connected to the automatic control circuit to make the water pump reciprocate between the states of pumping water and stopping pumping:

[0033] 1) The water pump stops, and the water level is between the low and high water lines;

[0034] 2) As the water is supplied to the user, the water level continues to drop below the low water level line, the pneumatic switch K1 is touched, and the water pump starts to pump water;

[0035] 3) The water level immediately rises above the low water level, and the pneumatic switch K1 is reversely touched;

[0036] 4) The water pump continues to pump water. Once the w...

Abstract

The invention discloses a water level detector which is durable, low in cost and good in performance and has no pollution to the water. The water level detector comprises a hollow tube; the lower end of the hollow tube is open and the upper end is provided with a pneumatic switch which is triggered when the water level reaches the opening. The invention further discloses a water pump automatic control system which controls the water pump to start or stop pumping through the water level detector, a water pump automatic control system which adopts the water level detector and is suitable for high stairs houses, and a water pump control circuit which is connected to the water level detector.

Description

technical field [0001] The invention relates to a water level detector, a water pump automatic control system for controlling the water pump to start / stop pumping water, a water pump automatic control system suitable for high-rise housing, and a water pump control circuit with parallel manual and automatic control circuits. Background technique [0002] In order to solve the problem of insufficient tap water pressure in high-rise housing, an upper pool can be set on the roof of the building. The tap water provided by the water plant is pumped (from the lower pool) to the upper pool to form a strong water pressure at a high place to supply high-level users. A water level detector is built in the upper pool, and the start switch of the water pump is controlled by the water level detector. In order to ensure that the upper pool has water supply at any time, when the water level is detected to be lower than the preset low water level, the start switch is turned on, and the wate...
