Description

Brushless speed governing magnetic water pump
Technical field
The present invention relates to a kind of brushless speed governing magnetic water pump, particularly relate to a kind of cooling for New energy automobile motor and warm The brushless speed governing magnetic water pump of wind system.
Background technology
The motor cooling of current domestic new-energy automobile and the warm air system of passenger vehicle all propose demand to electric water pump, at present New-energy automobile producer to fit into saliva pump, include brush motor drive, brushless electric machine drive, mechanical seal straight Connect transmission, magnetic drives.Wherein with the water pump longest-lived of brushless magnetic drives, run the most reliable, conventional water can be avoided The later leakage problem of pump operation time length, but price is the most expensive.And the domestic main engine plants of passenger vehicle warm air system are to install state The mechanical seal brush motor water pump produced is main, its low price but the life-span short, fault rate is high, virtually adds and safeguards into This.
Along with the popularization of new-energy automobile, the demand of brushless magnetic water pump, by increasing, subtracts to comply with national energy-saving The policy of row, the present invention proposes a kind of brushless magnetic water pump, and adds speed-regulating function, thus more energy efficient, and the water pump life-span also will Longer.
Summary of the invention
The present invention provides a kind of for New energy automobile motor cooling and the brushless speed governing magnetic water pump of warm air system.This water Pump includes magnetic, brshless DC motor, fan, driving plate in impeller, pump case, separation sleeve, magnetic shaft coupling outer magnetic, magnetic shaft coupling With external speed governing box.
The technical solution used in the present invention is as follows: pump case uses scroll casing type inner chamber according to fluid mechanics principle, at utmost Upper reduction water resistance, magnetic shaft coupling is divided into magnetic in the outer magnetic of magnetic shaft coupling and magnetic shaft coupling, and it links coupling pump as power Head can reach the static seal of non-water sealed structure, and DC brushless motor uses pulse modulation technology to realize the soft start of water pump and stepless Speed governing, by the improvement to phase changer so that the service life of commutation structure and rotor is longer, and the internal circuit driving plate is permissible Intelligent decision motor rotor position, abandons the position sensor of tradition use, and reserved communication module, provides for Based Intelligent Control Interface, separately possesses intelligent alarm and defencive function, and fan is centrifugal fan, plate can be driven to dispel the heat motor, speed governing box root According to cooling or the actual condition of warm air system, the setting of water pump rated speed can be realized.
The brushless speed governing magnetic water pump of the present invention also added many defencive functions, such as overload protection, anhydrous autostop Protection and anti-reverse protection.
Described overload protection shows as water pump operation electric current and exceedes maximum safe current value 15A of setting, produces stream After situation, water pump is the most out of service, attempts restarting after waiting 15s.
Described anhydrous automatic shutdown protection shows as pump monitoring to after pipeline hydropenia, and water pump stops after dallying 30 minutes Machine, has blinking red lamp.
Described anti-reverse protection shows as reverse power connection and does not works, and bright orange lamp is pointed out.
For common brushless magnetic water pump, the present invention uses magnetic drives structure, when water pump can be avoided long Between run and the problem of leakage occur, additionally with add arrangements for speed regulation and protection device, thus water pump is more energy-conservation, service life Also it is greatly improved.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the reality of the present invention Execute example together for explaining the present invention, be not intended that limitation of the present invention.
Fig. 1 is the structure sectional view of brushless magnetic water pump.
