Description
Technical field
The utility model relates to a kind of Mini gear pump of resistance to grinding.
Background technique
Conventional tooth wheel pump comprises protecgulum, bonnet, ceramic pump shaft, plastic sleeve, gear, rotor and magnetic cover, and because ceramic pump shaft easily fractures, plastic sleeve is not wear-resisting, all greatly affects the working life of gear pump.If particularly by conventional tooth wheel pump for delivery of the liquid that has particle, be easy to cause the end face Fast Wearing of the protecgulum adjacent with gear, bonnet, cause shortening the working life of gear pump.
Model utility content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of simple in structure, Mini gear pump of resistance to grinding of increasing the service life.
The utility model adopts following technological scheme: a kind of Mini gear pump of resistance to grinding, comprise protecgulum (1), bonnet (2), wolfram steel axle (3), gear (5), rotor (8) and magnetic cover (9), protecgulum is fixedly connected with by dowel (6), rotor is connected with gear (5) by wolfram steel axle (3), gear (5) is positioned at engagement chamber (12), rotor is built in magnetic cover (9), it is characterized in that: the end face that protecgulum (1) is adjacent with gear (5) is inlaid with wolfram steel layer (4), the end face that bonnet (2) is adjacent with gear (5) is inlaid with wolfram steel layer (4).
Wolfram steel axle (3) outside of the utility model Mini gear pump of resistance to grinding is provided with Ceramic shaft sleeve.Between magnetic cover and bonnet, by seal ring (11) sealing, between magnetic cover and sealed picture, by gland (7), compress.
Compare with conventional tooth wheel pump, the utlity model has simple in structure, resistance to grinding, and can not produce the feature of corrosion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic cross-section of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, illustrate mode of execution of the present utility model.
As shown in Figure 1 and Figure 2, a kind of Mini gear pump of resistance to grinding, comprise protecgulum 1, bonnet 2, wolfram steel axle 3, gear 5, rotor 8 and magnetic cover 9, protecgulum 1 is fixedly connected with by dowel 6 with bonnet 2, rotor is connected with gear 5 by wolfram steel axle 3, and gear 5 is positioned at engagement chamber 12, and rotor 8 is built in magnetic cover 9, the end face that protecgulum 1 is adjacent with gear 5 is inlaid with wolfram steel layer 4, and the end face that bonnet 2 is adjacent with gear 5 is inlaid with wolfram steel layer 4.
Magnetic cover 9 is fixedly connected with by fastening screw 13 with bonnet 2.Protecgulum 1, bonnet 2 are provided with seal ring 14 with engagement 12 contacting points, chamber respectively.Between magnetic cover 9 and bonnet 2, be provided with the seal ring 11 that is O type, magnetic cover 9 and seal ring 11 also has gland 7 for compressing being connected between magnetic cover and bonnet.Wolfram steel axle 3 outsides are provided with Ceramic shaft sleeve 10, and stupalith comprises: zirconium oxide, aluminium oxide, silicon nitride etc., Ceramic shaft sleeve 10 can protect wolfram steel axle can not be worn.Due to the high hardness of wolfram steel material, and self have certain toughness, wolfram steel axle does not easily fracture in the time of can not looking like pottery as pump shaft.Protecgulum 1, bonnet 2 are stainless steel casing.
The wolfram steel layer that protecgulum, bonnet are inlayed at its end face can not wear away both ends of the surface, and stainless steel casing is corrosion never, can greatly widen application industry of the present utility model and scope.Therefore, the utlity model has simple in structure, resistance to grinding, and can not produce the feature of corrosion.
Claims (4)
1. the Mini gear pump of resistance to grinding, comprise protecgulum (1), bonnet (2), wolfram steel axle (3), gear (5), rotor (8) and magnetic cover (9), protecgulum (1) is fixedly connected with by dowel (6), rotor is connected with gear (5) by wolfram steel axle (3), gear (5) is positioned at engagement chamber (12), rotor is built in magnetic cover (9), it is characterized in that: the end face that protecgulum (1) is adjacent with gear (5) is inlaid with wolfram steel layer (4), the end face that bonnet (2) is adjacent with gear (5) is inlaid with wolfram steel layer (4).
