New electric water pump

Abstract

The invention discloses a novel electric water pump, and the novel electric water pump comprises a motor and a water pump, the motor is fixedly connected to the water pump, the motor comprises a drive part and a control part, the control part comprises a fixing shell, a chip plate is formed in the fixing shell, the chip plate is fixedly connected to the fixing shell, the chip plate is provided with an integrated chip, the integrated chip is fixedly connected to the chip plate, the drive part comprises a brushless stator and a brushless rotor, the brushless stator is sleeved out the brushless rotor. The novel electric water pump has the characteristic of compact structure, reliable and simple use, low noise, saving on energy and environment friendly, intelligent control and programming, also has the function of water out protection, overload protection, reverse connection protection and speed adjustment, the fault of the pump can be reduced, the use efficiency and reliability of the novel pump can be raised and the water pump and the motor can be effectively protected.

Description

technical field [0001] The invention relates to the electromechanical field, and more specifically, the invention relates to a novel electric water pump. Background technique [0002] At present, the water pump is a general-purpose machine for transporting liquid media, and it is the heart of liquid transport for various mechanical equipment, and it is also a large energy consumer. During the use of pumps in the prior art, there are the following problems: (1) The noise of the pump operation (2) If the water pump has insufficient pump lift or insufficient water output (about the same time), it cannot be corrected on the original basis, only the impeller or the water pump can be replaced; (3) When the water pump is in the initial stage of operation, often It is easy to make mistakes in the direction of rotation of the pump, which is a great disadvantage for pumps that do not allow reverse rotation. It is impossible to observe the reverse rotation of the pump from the outside,...

[0002] At present, the water pump is a general-purpose machine for transporting liquid media, and it is the heart of liquid transport for various mechanical equipment, and it is also a large energy consumer. During the use of pumps in the prior art, there are the following problems: (1) The noise of the pump operation (2) If the water pump has insufficient pump lift or insufficient water output (about the same time), it cannot be corrected on the original basis, only the impeller or the water pump can be replaced; (3) When the water pump is in the initial stage of operation, often It is easy to make mistakes in the direction of rotation of the pump, which is a great disadvantage for pumps that do not allow reverse rotation. It is impossible to observe the reverse rotation of the pump from the outside, causing the performance of the pump to be too low, and it is judged that the pump cannot work normally. 4) During the operation of the pump, if the operating current of the pump exceeds the rated current of the motor, the current treatment method is generally to connect a fuse to the outside of the motor to protect the motor. If the rated current is exceeded, the fuse will blow to protect the motor; or During the production process, the power of the original motor is made slightly higher than the power of the original design motor, which is very inconsistent with the current society's requirements for energy saving and emission reduction; (5) If the unattended pump is running without load , due to unmanned monitoring, the pump will always run, that is, the pump has been doing useless work and wasting electricity. At the same time, because there is no water in the pump, the rotating parts inside the pump will be dry-grinded, which will damage the parts of the pump and cause the pump to malfunction.
