Double-source combined water supply device

Abstract

The invention discloses a double-source combined water supply device. The double-source combined water supply device is composed of a water supply unit A and a water supply unit B and supplies water to users in a combined mode through the water supply unit A and the water supply unit B. The water supply unit A and the water supply unit B respectively comprises a water supply pump unit with frequency converter control, a control unit of the water supply pump unit, a water tank, an electric valve, a detecting instrument and a pressure water source pipe, wherein the water tank and the pressure water source pipe are mounted in parallel; the water tank serves as the water reservoir for the pressure water source pipe, the outlet of the water tank is provided with the electric valve, and the water tank is connected with the pressure water source pipe through the electric valve; the pressure water source pipe, which is disposed in front of the part where the electric valve and the pressure water source pipe are connected, is provided with the detecting instrument. The double-source combined water supply device has the advantage that the water supply unit A and the water supply unit B supply water to the users in the combined mode and can be automatically switched to each other, so that water supply security can be greatly enhanced. The double-source combined water supply device is particularly applicable to a system with two or more pressure water source pipelines supplying water simultaneously.

Description

technical field [0001] The invention relates to the technical field of pressurized water supply, in particular to a combined water supply device with dual water sources. Background technique [0002] At present, the water supply equipment in the prior art mostly uses a single set of pumps or water tanks for water supply, and the reliability of the water supply is relatively poor, and it is easy to cause water interruption due to equipment failure, which affects the normal water supply. Contents of the invention [0003] The object of the present invention is to provide a double water source joint water supply device with good water supply safety and high reliability. [0004] The technical solution adopted by the present invention to solve the technical problem is: the dual water source joint water supply device is composed of a water supply unit A and a water supply unit B, and the water supply unit A and the water supply unit B jointly supply water to the user, and the w...
