Abstract
The utility model discloses a pump cover for a chemical flow magnetic drive pump. The pump cover comprises a cover body, a shaft hole on the center of the cover body, and a backflow hole which is in one or several broken lines shape and is arranged on the cover body. The backflow hole comprises an inclined section and a horizontal section, and an annular sealed groove is arranged outside of the shaft hole on the cover body. The pump cover is novel in structural design. The backflow hole combines an inclined section and a horizontal section, and the backflow pressure is huge. Cooling and circulation effects are excellent, and the entire performance of the pump is improved. And, the service lifetime is prolonged.
Description
Technical field:
The utility model relates to the pump manufacture field, relates in particular to a kind of chemical-process magnetic drive pump and uses pump cover.
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 return port of the pump cover of original magnetic drive pump is a straight hole, and return pressure is less, and it is insufficient to reflux, and cooling, the circuit effect is relatively poor, and sealing effect is bad.
The model utility content:
In order to remedy the deficiency of existing technology, the purpose of the utility model provides a kind of chemical-process magnetic drive pump and uses pump cover, has improved the backflow effect effectively.
The technological scheme of the utility model is following:
The chemical-process magnetic drive pump is used pump cover, comprises lid, and the lid center is provided with axis hole, it is characterized in that: described lid is provided with the return port of one or several broken line shape, and return port is made up of tilting section and horizontal segment.
Described chemical-process magnetic drive pump is used pump cover, it is characterized in that: the outside that is positioned at axis hole on the described lid is provided with the seal groove of annular.
Described chemical-process magnetic drive pump is used pump cover, it is characterized in that: keeping to the side on the described lid has several mounting holes along annular spread.
The utility model has the advantages that:
The utility model structural design is novel, and return port is tilting section and horizontal segment combination, and return pressure is big, cools off, circuit is effective, improved the overall performance of pump, prolonged working life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
The chemical-process magnetic drive pump is used pump cover with pump cover, comprises lid 1, and lid 1 center is provided with axis hole 2, and lid 1 is provided with the return port of one or several broken line shape, and return port is made up of tilting section 3 and horizontal segment 4.
The outside that is positioned at axis hole 2 on the lid 1 is provided with the seal groove 5 of annular.
Keeping to the side on the lid 1 has several mounting holes 6 along annular spread.
