Description
Technical Field
The invention belongs to the technical field of pumps, relates to a pump, and particularly relates to a permanent magnet direct-current variable-frequency electric pump.
Background
The common electric pump comprises a pump body with a built-in impeller and a motor for driving the impeller to work, wherein a water outlet and a water inlet are formed in the pump body, and when the pump works, water enters the pump body from the water inlet and is sprayed out from the water outlet after being accelerated by the impeller. For reducing the volume, improve the rotational speed, reduce the energy consumption, obtain great lift simultaneously, need improve the structure of electric pump, if to reach above-mentioned purpose, the common mode is to replace asynchronous machine with the permanent-magnet machine who takes the converter, the converter includes the circuit board and installs the rectifier bridge on the circuit board, the IPM module, a chip, electric capacity etc. rectifier bridge and IPM module wherein have higher heat dissipation requirement, if the converter sets up in confined, narrow and small casing, the heat that its work produced is difficult to distribute, electronic component can be damaged to the heat is too high, and then influence the use of electric pump. The existing variable-frequency electric pump is complex in structure, the size is reduced, the structure is simplified and is not favorable, the maintenance and the assembly are inconvenient, a control panel in the variable-frequency electric pump is a main control panel and an auxiliary control panel, the main control panel controls the operation of a motor, and an auxiliary control panel controls an external indicator of a pump body to display the operation condition of the pump body, so that the structure is complex.
