Abstract
The utility model discloses a magnetic pump. Magnetic pump includes pump case, separation sleeve, combined rotor, back lid and bolster, the pump case with the separation sleeve encloses to close and forms a pump chamber, combined rotor with back lid accept in in the pump chamber, combined rotor includes bearing, axle sleeve, thrust ring and main shaft, the bearing housing is located on the outer peripheral surface of main shaft, the axle sleeve cover is located on the outer peripheral surface of bearing, the thrust ring cover is located the main shaft and with a tip counterbalance of axle sleeve connects, back lid cover is located the axle sleeve and with another tip counterbalance of axle sleeve connects, the bolster is located the axle sleeve with between the lid of back. The utility model provides a magnetic pump, it is placed the bolster makes back lid with axle sleeve contact becomes indirect contact. Magnetic pump starts when producing in the twinkling of an eye axial thrust, the bolster plays the cushioning effect, has reduced the probability that the axle sleeve damaged has prolonged the life of axle sleeve.
Description
Technical field
This utility model relates to a kind of pump technical field, particularly relates to a kind of magnetic drive pump.
Background technology
Magnetic drive pump is hermetically sealed with it, No leakage, the distinguishing feature such as corrosion-resistant, it has also become the conventional equipment of the departments such as China's oil chemical industry. Along with the industry such as China's oil, chemical industry develops rapidly, the demand of magnetic drive pump product is increasing, the dependability therefore how improving product has become the problem that technical staff first has to consider.
The flow passage components of magnetic drive pump are corrosion-resistant material, wherein, determine that the critical component in magnetic drive pump service life is thrust ring, sliding bearing and axle sleeve (being commonly called as three-piece). Based on the particular/special requirement of above-mentioned use, in recent years, above-mentioned three-piece was all selected excellent performance, corrosion-resistant strong silicon carbide material to act as first-selection by each design, manufacturer.
In correlation technique, during magnetic drive pump work, owing to lift is high, producing very big moment axial thrust and then collision bonnet during startup, therefore, the axle sleeve directly contacted with bonnet is easily damaged, and causes that the service life of axle sleeve reduces, adds the maintenance cost of magnetic drive pump.
Therefore, it is necessary to provide the new magnetic drive pump of a kind of structure to solve the problems referred to above.
Utility model content
This utility model solves the technical problem that and is to provide a kind of magnetic drive pump avoided axle sleeve to be subject to moment axial thrust impact and damage.
The magnetic drive pump that this utility model provides, including pump case, separation sleeve, combined rotor, bonnet and bolster, described pump case and described separation sleeve enclose formation one pump chamber, described combined rotor and described bonnet are contained in described pump chamber, described combined rotor includes bearing, axle sleeve, thrust ring and main shaft, described bearing holder (housing, cover) is located on the external peripheral surface of described main shaft, described axle sleeve is sheathed on the external peripheral surface of described bearing, described thrust ring is sheathed on described main shaft and the one end with described axle sleeve abuts against, described bonnet is sheathed on described axle sleeve and the other end with described axle sleeve abuts against, described bolster is located between described axle sleeve and described bonnet.
Preferably, described bonnet has groove near one end of described axle sleeve, and described bolster is embedded in described groove.
Preferably, described bolster be in elastic washer, flat spring washer or spring washer any one.
Preferably, described main shaft is solid shafting.
Compared to prior art, the magnetic drive pump of offer of the present utility model, described bolster is positioned between described bonnet and described axle sleeve, makes described bonnet and the described axle sleeve way of contact become mediate contact. When the startup of described magnetic drive pump produces very big moment axial thrust, described bolster can effectively cushion this axial thrust, makes the active force suffered by described axle sleeve reduce, thus reducing the probability that described axle sleeve damages because of axial thrust, extend the service life of axle sleeve, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model magnetic drive pump.
Detailed description of the invention
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Refer to Fig. 1, for the structural representation of this utility model magnetic drive pump. Described magnetic drive pump 1 includes pump chamber 11, combined rotor 12, bonnet 13, pump case 14, separation sleeve 15 and bolster 16. Described pump chamber 11 is to be enclosed formed by described pump case 14 and described separation sleeve 15. Described combined rotor 12 and described bonnet 13 are contained in described pump chamber 11. Described bolster 16 is located between described bonnet 13 and described combined rotor 12.
Described combined rotor 12 includes bearing 121, axle sleeve 122, main shaft 123 and thrust ring 124. Described bearing 121 is sheathed on the external peripheral surface of described main shaft 123. Described axle sleeve 122 is sheathed on the external peripheral surface of described bearing 121. Described thrust ring 124 is sheathed on described main shaft 123 and the one end with described axle sleeve 122 abuts against, described bonnet 13 is sheathed on described axle sleeve 122 and the other end with described axle sleeve 122 abuts against, and described bolster 16 is located between described axle sleeve 122 and described bonnet 13.
Described bearing 121 is sliding bearing.
Described axle sleeve 122 is carborundum axle sleeve.
Described main shaft 123 is solid shafting.
Described thrust ring 124 is carborundum thrust ring. Carbofrax material is a kind of material corrosion-resistant, wear-resistant, resistant to elevated temperatures, is mainly used in precision, tightness requires on high engineering goods, such as high-pressure pump, magnetic drive pump etc. But, carbofrax material active force is frangible time big, in order to alleviate axial force during pump work, adopts described bolster 16 to alleviate its active force.
Described bonnet 13 has groove 131 near one end of described axle sleeve 122. Described bolster 16 is embedded in described groove 131, and described bolster 16 is used for cushioning the axial thrust produced between described bonnet 13 and described axle sleeve 122.
The mounting means of described bolster 16 is not limited to be embedded in the groove 131 of described bonnet 13, the mode that fastener (not shown) is set on described bonnet 13 can also be used in, described bolster 16 and described fastener clamping, make described bolster 16 be fixed on described bonnet 13.
Described bolster 16 is any one in elastic washer, flat spring washer or spring washer. The material of described bolster 16 is stainless steel 304, and it has wear-resisting, decay resistance preferably.
Compared to prior art, the magnetic drive pump of offer of the present utility model arranges described bolster by covering in the rear between described axle sleeve, the way of contact making described bonnet and described axle sleeve becomes mediate contact, when the startup of described magnetic drive pump produces very big moment axial thrust, described bolster can effectively cushion this axial thrust, the active force suffered by described axle sleeve is made to reduce, thus reducing the probability that described axle sleeve damages because of axial thrust, extend the service life of axle sleeve, reduce maintenance cost.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, all in like manner include in scope of patent protection of the present utility model.
