Problems solved by technology

[0012] This creates a risk of the water being lost or leaked into the dielectric coolant, which compromises the dielectric properties of the coolant even in the presence of very small amounts of water, with subsequent loss of operation of the electric motor. impossibility

Embodiment Construction

[0035] The figures show an electric motor 1 comprising a body 11 hermetically closed by two covers 12 and 13 and exhibiting axial cooling fins 110 .

[0036] The stator 2 of the motor is fixed to said body 11; the rotor 3 is in turn splined to a shaft 31, the ends of which are supported by bearings 312 and 313 which are held by covers 12 and 13 respectively.

[0037] The cover 12 has a sealing ring 122 of the output seat of the shaft 31 and likewise the cover 13 has a sealing ring 133 in the output seat of the shaft 31 and between the covers 12 and 13 There are two front heads 134 and 135 .

[0038] The end of said shaft 31 protruding from said cover 13 has at its axial groove portion a splined fan 15 enclosed in a casing 16 fixed to said main body 11, and the casing 16 wraps a part of the cooling fan 110.

[0039] The end of the shaft 31 protruding from the cover 12 has an inclined plate 161 splined to a hydraulic pump 160 contained in a compartment 162 firmly constrained t...

Abstract

An electrical water cleaner includes an electric motor and a hydraulic pump activated thereby, a sealed external cylindrical casing containing the motor, a shaft of which is associated to a rotor and exits the casing through the two circular bottom walls thereof in a presence of seal rings, and bears at an end thereof means for activating the pump, and at an opposite end thereof an air-cooling fan, the fan being contained in a substantially cylindrical external casing which at least in part develops parallel to the cylindrical wall of the casing, a cylindrical stator of which is fixed internally of the casing, in which the casing is sealed and contains a quantity of dielectric cooling liquid able to convey heat generated by the electric motor into the cylindrical wall of the casing, from which the heat is removed by the air generated by the cooling fan.

Description

technical field [0001] The invention relates to the field of water purifiers, which are machines comprising an electric motor and a pump forming a single unit of small dimensions, capable of producing water contained between 5 and 11 liters per minute contained between 70 and 150 bar flow. Background technique [0002] In known machines, cooling of electric motors of this type is usually done with air. [0003] The motors that are often used have an absorbed power of about from 1.8KW to 3KW and are of the type exhibiting a stator and a rotor contained in a main body. [0004] The body is impinged by a cooling air flow generated by a fan splined to one end of the motor's rotating shaft and is typically provided with external cooling fins. [0005] Prolonged use of the water purifier, especially in hot climates, causes an undesired increase in the temperature of the rotor and stator, which negatively affects the performance of the electric motor. [0006] Special technical ...
