Abstract
The utility model discloses a double support bearing chemical flow magnetic drive pump, comprising a pump body and a support installed on two sides of a base; a pump cover is provided between the pump body and the support; the support is provided with a motor; an impeller is installed in a pump cavity; a pump shaft traverses the pump cavity; one end of the pump shaft is fixed to the impeller; a separation sleeve is installed on a central part of the pump shaft; the other end of the pump shaft is in connection with an output shaft of the motor; bearings are sleeved between the pump shaft and the pump cover as well as well between the pump shaft and the separation sleeve; ring-shaped oil grooves are provided on inner walls of the bearings. The double support bearing chemical flow magnetic drive pump has a novel design; a rotor part employs two bearings for support; the operation is smooth; a whole performance of the pump is raised and a service life is prolonged.
Description
Technical field:
The utility model relates to the pump manufacture field, relates in particular to a kind of dual-supporting bearing chemical-process magnetic drive pump.
Background technique:
Magnetic drive pump is made up of pump, magnetic driver, motor three parts.The critical component magnetic driver is made up of outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve.When magnet rotor outside the motor drives rotated, magnetic field energy penetrated air gap and namagnetic substance, drove the interior magnet rotor that links to each other with impeller and did rotation synchronously, and the non contact transmission of realization power is converted into static seal with motive sealing.Because pump shaft, interior magnet rotor be by the pump housing, separation sleeve complete closed, thereby thoroughly solve " run, drip, leak " problem, eliminated the potential safety hazard that the oil-refining chemical industry is inflammable, explosive, poisonous, hazardous medium leaks through pump seal.
The rotor part of original magnetic drive pump is only used a bearing, and the user feedback axle is easily broken, and rotor part is changed frequent.
The model utility content:
In order to remedy the deficiency of existing technology, the purpose of the utility model provides a kind of dual-supporting bearing chemical-process magnetic drive pump, has improved the support strength of magnetic drive pump rotor part effectively, and running has steadily prolonged working life.
The technological scheme of the utility model is following:
Dual-supporting bearing chemical-process magnetic drive pump comprises the pump housing and the support that are installed on the base both sides, is provided with pump cover between the pump housing and the support; Motor is installed on the support, impeller is installed in the pump chamber, have pump shaft to pass pump chamber; Pump shaft one end and described impeller are fixed; The pump shaft middle part is equipped with separation sleeve, and the pump shaft the other end is connected with the output shaft of motor, it is characterized in that: be set with bearing between described pump shaft and pump cover, pump shaft and the separation sleeve.
Described dual-supporting bearing chemical-process magnetic drive pump is characterized in that: described bearing inner wall is provided with the oil groove of annular.
The utility model has the advantages that:
The utility model structural design is novel, and the rotor part place adopts two bearing supportings, and running has steadily improved the overall performance of pump, has prolonged working life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the local enlarged diagram of the utility model.
Embodiment:
Referring to Fig. 1:
Dual-supporting bearing chemical-process magnetic drive pump comprises the pump housing 2 and support 3 that are installed on base 1 both sides, is provided with pump cover 4 between the pump housing 2 and the support 3; On the support 3 motor is installed, impeller 5 is installed in the pump chamber, have pump shaft 6 to pass pump chamber; Pump shaft 6 one ends and impeller 5 are fixing; Pump shaft 6 middle parts are equipped with separation sleeve 7, and pump shaft 6 the other ends are connected with the output shaft of motor 8, are set with bearing 9 between pump shaft 6 and pump cover 4, pump shaft 6 and the separation sleeve 7.
Bearing 9 inwalls are provided with the oil groove 10 of annular.
