Abstract
(EN)
A motor pump unit and a hand-held high-pressure cleaning machine comprising the motor pump unit. The motor pump unit (20) comprises a micro motor (22) and a mini pump (21); a motor housing (29) is provided with a sealed chamber I (30) and an inner housing (52) located at an inner ring of the sealed chamber I (30), and a stator core (7) clings to the inner housing (52) to form a heat conduction channel; the motor housing (29) is provided with at least one cooling channel I (17), a water inlet I (19), and a water outlet I (23); the water inlet I (19) is connected to an external water source, and the water outlet I (23) is in communication with a pump water inlet (13); a pump housing (58) is provided with at least one cooling channel II (24), a water inlet II (25), and a water outlet II (26); and the water inlet II (25) is connected to an external water source or the water outlet I (23), and the water outlet II (26) is connected to the pump water inlet (13). The waterproofing grade of a motor and an entire machine can reach IPX7 or higher, and a machine is safer and more reliable.

L'invention concerne un groupe motopompe et une machine de nettoyage à haute pression portative comprenant l'unité de pompe à moteur. Le groupe motopompe (20) comprend un micro-moteur (22) et une pompe miniature (21). Un carter de moteur (29) est pourvu d'une chambre étanche I (30) et d'un boîtier interne (52) situé au niveau d'un anneau interne de la chambre étanche I (30), et un noyau de stator (7) s'accroche au boîtier intérieur (52) pour former un canal de conduction de chaleur. Le carter de moteur (29) est pourvu d'au moins un canal de refroidissement I (17), d'une entrée d'eau I (19) et d'une sortie d'eau I (23). L'entrée d'eau I (19) est reliée à une source d'eau externe, et la sortie d'eau I (23) est en communication avec une entrée d'eau de pompe (13). Un carter de pompe (58) est pourvu d'au moins un canal de refroidissement II (24), d'une entrée d'eau II (25) et d'une sortie d'eau II (26). L'entrée d'eau II (25) est reliée à une source d'eau externe ou à la sortie d'eau I (23), et la sortie d'eau II (26) est reliée à l'entrée d'eau de pompe (13). Le degré d'étanchéité à l'eau d'un moteur et d'une machine entière peut atteindre IPX7 ou plus, et une machine est plus sûre et plus fiable.
