Description
Technical field
The utility model relates to a kind of pump, particularly a kind of Heat-transfer Oil Pump.
Background technique
Existing oil pump comprises motor, is connected to the pump housing by linkage section and motor, and be provided with the impeller be arranged on pump shaft in the pump housing, pump shaft connects with motor output shaft.The oil pump heat-conducting effect of this structure is poor, and when particularly conveying has the medium of certain heat, temperature rise produces bearing and miscellaneous part and has a strong impact on, and reduces working life.
Summary of the invention
The purpose of this utility model is to provide a kind ofly operationally has great heat radiation effect, elongate member life-span, the Heat-transfer Oil Pump of increasing work efficiency, and overcomes the deficiencies in the prior art.
Heat-transfer Oil Pump of the present utility model, the pump housing comprise motor, being connected by linkage section with motor, the pump cover matched with the pump housing, have the impeller be arranged on pump shaft termination at the inner chamber of the pump housing, pump shaft connects with the output shaft of motor; There is center hole one end that described pump shaft connects with the output shaft of motor, and the output shaft of motor directly inserts in described center hole, is connected between described center hole and the axle shaft of motor by key; In the middle part of described linkage section, side is Openworks shape, is coated with case outside linkage section, and case is arranged with open-work; Pump shaft is equipped with fan blade near motor one end; Rolling bearing is provided with between the endoporus of one end that described linkage section connects with motor and pump shaft; Sliding bearing is provided with between described pump cover endoporus and pump shaft, pump shaft is set with seal casinghousing, radiating fin is provided with outside seal casinghousing, seal casinghousing one end is fixedly connected with described pump cover, the other end inserts sealing cover endoporus, between sealing cover and seal casinghousing, be provided with seal ring, sealing cover is sleeved on outside pump shaft, and sealing cover is fixed in the middle part of described linkage section and also and between linkage section is provided with seal ring; At sealing cover endoporus, place is installed with fixed ring, and pump shaft is installed with rotating ring, forms the mechanical seal structure to sliding bearing.
Described pump cover is positioned at inner side and is provided with thermal baffle.
Heat-transfer Oil Pump of the present utility model, operationally, fan blade is rotated with pump shaft, adopt forced air cooling and heat radiating fin structure, reduce the transition region sectional area in high-temperature zone and normal temperature interval, by air-cooled further minimizing heat conduction, and be the thermal baffle that the back side installs additional inside pump cover, reduce heat radiation, thus the thermal distortion realizing pump is less.
Motor shaft connects with pump shaft plug-in type, safe and reliable, and stability is higher, shortens the axial distance of pump further.
The support of pump adopts front slide bearing, rear rolling bearing structural type.Front end adopts high temperature resistant sliding bearing, medium self-lubrication; Rear end adopts grease lubrication.Improve the working life of bearing.
It is mechanical seal structure between two bearings, by the medium lubrication after cooling between sealing friction pair, do not need to adopt expensive high-temperature bellow sealing to meet the demands, and be Floating connection between seal casinghousing and sealing cover, and adopt O type circle to seal, overcome the seal leakage problem because thermal distortion causes.
This pump has structure simple, easy accessibility, and external form is compact attractive in appearance, and floor space is little, and operating cost is cheap, and stable performance uses the advantages such as reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 1 is motor, 2 is linkage section, and one end of linkage section 2 is fixedly connected with by the front end flange of bolt with motor 1.The other end of the section of connecing 2 is fixedly connected with the pump housing 9, pump cover 13.In the inner chamber that the pump housing 9 and pump cover 13 form, there is the impeller 10 be arranged on pump shaft 4 termination and go out spacing by nut 12 axle, being provided with choma 11 in the center of the pump housing 9.
Pump shaft 4 connects with the output shaft of motor 1, and its Placement is that one end that pump shaft 4 connects with the output shaft of motor 1 has center hole, and the output shaft of motor 1 directly inserts in center hole, is provided with connecting key between the axle shaft of center hole and motor 1.
In the middle part of linkage section 2, side is Openworks shape, i.e. connected by equally distributed connection rib between two end flange of linkage section 2.Outside linkage section 2, be coated with case 7, case 7 is arranged with open-work.Fan blade 5 is equipped with in one end near motor 1 on pump shaft 4.
Rolling bearing 3 is provided with between the endoporus of one end that linkage section 2 connects with motor 1 and pump shaft 4.
Be provided with sliding bearing 15 between pump cover 13 endoporus and pump shaft 4, pump shaft 4 is set with seal casinghousing 16, outside seal casinghousing 16, be provided with radiating fin.Seal casinghousing 16 one end and pump cover 13 are fixedly connected with by screw and are provided with sealing gasket, and the other end inserts sealing cover 8 endoporus, between sealing cover 8 and seal casinghousing 16, be provided with seal ring.Sealing cover 8 is sleeved on outside pump shaft 4, and sealing cover 8 is fixed in the middle part of linkage section 2 and also and between linkage section 2 is provided with seal ring.At sealing cover 8 endoporus, place is installed with fixed ring 18, and pump shaft 4 is installed with rotating ring 17, forms the mechanical seal structure to sliding bearing (15).When pump shaft 4 rotates, rotating ring 17 rotates thereupon, and fixed ring 18 is relative with sealing cover 8 fixing.Rotating ring 17 seals with the end face Relative friction of fixed ring 18.Pump cover 13 is positioned at inner side i.e. rear side and is fixedly connected with thermal baffle 14 by screw.
