Booster pump and water suction pump time staggered control system for water purifier

Abstract

The invention discloses a booster pump and water suction pump time staggered control system for a water purifier. The booster pump and water suction pump time staggered control system includes a mainpower supply, a booster pump and a submersible pump, the booster pump and the submersible pump are opened in a time staggered mode through a time staggering controller, the booster pump is connected with the main power supply through a first relay, and the first relay is used for controlling the disconnection and connection of the booster pump and the main power supply and connected with the timestaggering controller; and the submersible pump is connected with the first relay through a second relay, and the second relay is used for controlling the disconnection and connection of the submersible pump and the main power supply and connected with the time staggering controller. By means of the booster pump and water suction pump time staggered control system, the fact that the booster pump and the submersible pump cannot work simultaneously is ensured, the simultaneous operation of the booster pump and the submersible pump is eliminated, the switching power supply of the water purifier is prevented from overloading, the low-current switching power supply can be configured for the water purifier, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a time-staggered control system for a booster pump and a water pump of the water purifier. Background technique [0002] In the prior art, a reverse osmosis water purifier with a built-in pure water tank generally adopts a submersible pump to pump water, and the submersible pump has the characteristics of large flow rate and long service life. However, water purifiers using submersible pumps generally have the following deficiencies: [0003] The full-load working current of the submersible pump reaches 0.7-1.0 amps, and the current of the booster pump in the water purification system reaches 0.5-2 amps. The current of the booster pump and the submersible pump form the two main currents of the water purifier. When the booster pump and the submersible pump work at full load at the same time, the current of the whole water purifier increases by 0.7-1.0 amps, and the corresponding sw...

Problems solved by technology

[0003] The full-load working current of the submersible pump reaches 0.7-1.0 amps, and the current of the booster pump in the water purification system reaches 0.5-2 amps. The current of the booster pump and the submersible pump form the two main currents of the water purifier. When the booster pump and the submersible pump work at full load at the same time, the current of the whole water purifier increases by 0.7-1.0 amps, and the corresponding switch power supply load configuration needs to increase by 1.0 amps or more, so that the cost of the switch power supply and the whole machine of the water purifier will be corresponding increase, reducing the production efficiency of the enterprise
