Abstract
The utility model discloses a replaceable rotor wear-resistant head structure of a rotor pump, which comprises a pump body, and further comprises a rotor body and a wear-resistant part, wherein the wear-resistant part is fixed on the rotor body and is in fit with the pump body; dovetail grooves are respectively formed on the wear-resistant part and the rotor body; and the wear-resistant part and the rotor body are bonded to form a whole through the dovetail grooves. The replaceable rotor wear-resistant head structure has the advantages that wear-prone parts adopt replaceable combined units, friction surfaces adopt composite non-metallic elastic materials, and the two materials are reliably and firmly combined by means of the dovetail grooves and bonding; with the elastic nonmetallic material on the surface of the rotor, the service life of the motor is prolonged, the fitting clearance is reduced and the pump efficiency is improved; different nonmetallic materials can be selected according to the media condition, the friction noise between the metal and nonmetallic material is lower, sparkles and heat during the operation are avoided, and the operation is safe and stable; and when the rotor is maintained or replaced, only the rotor wear-resistant part is required to be replaced without dismounting the whole rotor, so that the workload and the maintenance cost are reduced.
Description
Technical field
The utility model relates to the electromechanical equipment field, is a kind of pump specifically, more specifically is a kind of rotator type displacement pump wear-resisting head structure.
Background technique
Rotator type displacement pump operational efficiency is low, the operation life cycle is short, noise is large, maintenance workload is large, expense is high, makes troubles for operation, management, the maintenance of pump.During pump operation the running clearance of metal parts determined the efficient of pump, along with the wearing and tearing of part, the increasing in gap causes the efficient of pump significantly to descend.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides the replaceable rotor wear-resisting head of a kind of rotor pump structure, and concrete scheme is as follows:
The replaceable rotor wear-resisting head of a kind of rotor pump structure comprises the pump housing, it is characterized in that: also comprise rotor body and wearing piece, described wearing piece is fixed on the rotor body, and described wearing piece cooperates with the pump housing.
Described wearing piece, rotor body all arrange dovetail groove, and described wearing piece, rotor body are integral by dovetail groove is bonding.
Described rotor body prolongs radially and is comprised of two-part, be respectively with the fixing body portion of axle and with the fixing attrition-resistant support part of wearing piece, described body portion and attrition-resistant support partial fixing are integral.
Described wearing piece is the composite non-metal elastic material.
The utility model has the advantages that: position easy to wear is removable assembly parts, and rubbing surface adopts the composite non-metal elastic material, and the combination of bi-material is dovetail groove and bonding, in conjunction with solid and reliable.Because the rotor surface nonmetallic material have elasticity, prolonged working life, reduce matching gap, thereby improved pump efficiency.Can select different nonmetallic material according to the medium situation, metal and non-metallic friction noise are little, spark, the heat of not producing in service, and security of operation is steady.When overhauling more exchanging rotor, needn't dismounting and change fall whole rotor, only need to change the friction rotor part, reduce workload, reduce maintenance cost.
Description of drawings
Fig. 1 is the utility model structure;
Fig. 2 is the wearing piece enlarged view.
Embodiment
Specify the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises the pump housing 1, also comprises rotor body and wearing piece 4, and described wearing piece 4 is fixed on the rotor body, and described wearing piece 4 cooperates with the pump housing 1.
As shown in Figure 2, described wearing piece 4, rotor body all arrange dovetail groove 41, and described wearing piece 4, rotor body are by dovetail groove 41 bonding being integral.
Described rotor body prolongs radially and is comprised of two-part, be respectively with the fixing body portion 3 of axle 5 and with the fixing attrition-resistant support part 2 of wearing piece 4, described body portion 3 is fixed into one with attrition-resistant support part 2.
Described wearing piece 4 is the composite non-metal elastic material.
