Be arranged circumferentially outer coolant flow channel (11) between described bearing housing (3) and the pump housing, and the liquid entering hole (9), the liquid outlet (4) that are communicated with described outer coolant flow channel (11) are set on the pump housing;
Be provided with the internal spiral cooling tube (5) be communicated with outer coolant flow channel (11) in described bearing housing (3), inject in described bearing housing (3) and be in the outside lubricant oil of internal spiral cooling tube (5).
Described outer coolant flow channel (11) is following structural type: bearing housing (3) outer ring surface arranges some raised lines (111) axially arranged, described raised line (111) and pump housing inwall are formed and are sealed and matched, and each raised line (111) are arranged the through hole for cooling liquid circulation.
Described raised line (111) and bearing housing (3) both sides end face establish opening (12), opening (12) the incorgruous setting of adjacent raised line (111).
The import (7) of described internal spiral cooling tube (5) and liquid entering hole (9) are between same two adjacent raised lines (111), and the outlet (10) of described internal spiral cooling tube (5) and liquid outlet (4) are between same two adjacent raised lines (111).
Described internal spiral cooling tube (5) peripheral hardware fin (8).
The quantity of described fin (8) is 1/5 ~ 1/2 of internal spiral cooling tube (5) length, and the thickness of fin (8) is 0.8 ~ 1.2mm.
Described liquid entering hole (9), liquid outlet (4) are arranged about rotating shaft (1) axisymmetrical, and described liquid entering hole (9) is arranged on pump housing bottom, and liquid outlet (4) is arranged on pump housing top.
The utility model has the advantages that: 1) the utility model changes the single type of cooling, adopt the dual-cooled structure of outer coolant flow channel and internal spiral cooling tube, greatly strengthen the oil temperature cooling effect of pump bearing;
2) the utility model is by the outer coolant flow channel of trough of belt, by the mode of the incorgruous setting of adjacent apertures, makes the flow of cooling water longer time, improves cooling effect;
3) the utility model internal spiral cooling tube peripheral hardware fin, finned and common cooling tube is compared, and finned cooling tube adds the area of contact with lubricant oil, and cooling effect is 20 to 100 times of common cooling tube, achieves significant technique effect.
In sum, the utility model has compact, the feature that heat exchange efficiency is high, thus effectively can extend the working life of pump and bearing.
