Abstract
A kind of magnetic drive pump pump cover, including pump cover body, the pump cover body are connected with impeller, and for connecting separation sleeve and axle sleeve；Counter balance pocket is formed between pump cover body and impeller.The circulation port for being used for taking away the heat produced in pump, the top wire hole for fixed hub and the screwed hole for installing separation sleeve are provided with pump cover body.The utility model has the advantages that axial force balance effect is good, technique is simple, rational in infrastructure.
Description
Technical field
The utility model is related to a kind of pump, more particularly to a kind of magnetic drive pump pump cover.
Background technology
At present, the light-duty magnetic drive pump of CQ series occupies larger market ratio, and the serial magnetic drive pump disadvantage is maintaining
Cycle is short, and most maintenance works are to change the consumable accessory inside magnetic drive pump.Due to the serial magnetic drive pump price city
Field is relatively low, does not take effective axial force balance mechanism generally, and axial force imbalance causes the master that magnetic drive pump inner part weares and teares
Reason is wanted, other damage of components in magnetic drive pump are also resulted in, magnetic drive pump inner part is frequently changed, to the production using client
Efficiency is affected greatly.
Tradition light-duty magnetic drive pump pump cover effect is single, only for separating pump housing chamber and separation sleeve inner chamber.
Utility model content
The purpose of this utility model, exactly in order to solve the above problems, there is provided a kind of magnetic drive pump pump cover.
In order to achieve the above object, the utility model employs following technical scheme：A kind of magnetic drive pump pump cover, including pump cover
Body, the pump cover body is connected with impeller, and for connecting separation sleeve and axle sleeve；Formed between the pump cover body and impeller flat
Weigh chamber.
The pump cover body is provided with the circulation port for being used for taking away the heat produced in pump.
The pump cover body is provided with the top wire hole for fixed hub.
The pump cover body is provided with the screwed hole for being used for installing separation sleeve.
The utility model has the following advantages that and feature as a result of above technical scheme：
1st, axial force balance effect is good：Pump cover and impeller, which coordinate, constitutes counter balance pocket, is the allusion quotation of magnetic force impeller of pump floating equilibrium
Type is designed, and can greatly prolong the consumable accessory life-span in pump with the axial force of active balance magnetic drive pump.
2nd, technique is simple, easily manufactured, low cost：The pump cover is that traditional pump cover and bearing block are integrated, and magnetic force
Pump shaft sleeve can be directly installed on the endoporus of pump cover by jackscrew, axle sleeve is interference fitted with bearing holder (housing, cover) without cumbersome technique,
Manufacturing process is lifted, and simple in construction, saves cost.
3rd, it is rational in infrastructure：Pump cover is provided with circulation port, can effectively take away the heat produced during pump operation, the isolation of magnetic drive pump
Set can be arranged on pump cover, effectively save the useful space in magnetic drive pump.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
Referring to Fig. 1, magnetic drive pump pump cover of the present utility model, including pump cover body 1, the pump cover body 1 is connected with impeller 2,
And for connecting separation sleeve and axle sleeve；Counter balance pocket 3 is formed between pump cover body and impeller.
Pump cover body of the present utility model is provided with the circulation port 11 for being used for taking away the heat produced in pump, for fixing axle
The top wire hole 12 of set and the screwed hole 13 for installing separation sleeve.
The utility model magnetic drive pump pump cover can install the endoporus of magnetic force pump shaft sleeve by design, set fixed magnetic force pump shaft
The top wire hole 12 of set fixes axle sleeve, changes tradition by toasting the method that magnetic force pump shaft sleeve is installed in interference, makes manufacturing process
It is simplified, installs also simpler, machining concentricity is also easier to ensure.
The utility model also utilizes each section fluid pressure of magnetic drive pump pump housing volute chamber, devises circulation port 11, can be with
Effectively take away the heat produced during magnetic force pump operation.
Pump cover is also encircled into counter balance pocket 3 with impeller, during magnetic force pump operation, impeller and the physical dimension energy of pump cover particular design
The axial force of magnetic drive pump is enough automatically adjusted, the internal rotor of magnetic drive pump keeps floating equilibrium, makes the abrasion condition of magnetic drive pump inner part
Substantially improved.
Screwed hole 13 is devised on pump cover, for installing the separation sleeve of magnetic drive pump, magnetic force pump seal series of security is improved,
Space in pump is saved simultaneously.
