Description

Booster pump with inductive and non-inductive functions

Technical Field

Background

The booster pump generally divide into the sensible booster pump among the prior art and does not feel the pressure boost originally, and the theory of operation of sensible booster pump does: the water outlet faucet is opened, the valve is pushed by natural water flow, the valve is opened to enable the magnet to move, the magnet moves to enable the magnet to be close to the steel spring pipe, the steel spring pipe is closed, a closing signal is transmitted to the water pump, and the water pump is started to normally work; when the water outlet faucet is closed, the valve returns to the original position through the force of the spring, the magnet is far away from the steel reed pipe, the steel reed pipe is disconnected, and the water pump stops working. However, the sensible booster pump also has the obvious defect that the booster pump cannot be started when the natural water flow is too small (less than 1L/min) or no natural water flow exists. The principle of the sensorless booster pump is that when the water pump is powered on and is in a standby state (working at low rotating speed and with power of 5W), when the water outlet faucet is opened, the change increment of the motor load (motor internal parameters and no sensing device is needed) is detected by control drive and exceeds set parameters, and the motor works normally at high speed; when the water outlet tap is closed. The control drive detects that the change decrement of the motor load (the internal parameter of the motor, and a sensing device is not needed) exceeds the set parameter, and the motor enters the standby state again. The defects of the non-inductive booster pump are as follows: 1. the water outlet faucet is opened at an ultra-slow speed, the load variation sensed by the driving cannot meet the set requirement, and the water outlet faucet cannot be started normally; meanwhile, the pump is always in a working state, and the loss is large.
