The inner cavity of the pump body is additionally provided with the overflow runner, and the overflow runner is provided with the overflow valve, so that the flow speed and the flow of the oil is remitted and controlled by the overflow valve to protect the electric pump rotor when the oil flow which passes through the pump body is overlarge, and the work of the electric pump can be safer and more reliable; and the inlet end at the inner cavity of the pump body is additionally provided with the filter screen, so that the impurity mixed in the oil can be effectively filtered out, and the quality of the oil which flows from the inlet can be guaranteed.
Description
Technical field
The utility model relates to the pump field, relates in particular to a kind of motor-drive pump.
Background technique
Motor-drive pump is the equipment of the convenient oil transportation metering of a kind of engineering machinery, at present existing portable motor-drive pump, its structure mainly comprises the pump housing, the inner chamber of the pump housing offers import and outlet, be provided with the motor-drive pump rotor between import and the outlet, the motor-drive pump rotor is provided with rotor blade, and oil enters from import, the motor-drive pump rotor blade of flowing through flows out from outlet at last.Because existing motor-drive pump less than the inner chamber at the motor-drive pump pump housing corresponding modulating valve is set or relief valve waits the flow velocity of controlling or regulate oil, so be located at the interior motor-drive pump rotor of the pump housing when the flow of oil is excessive, rotor blade is stuck easily, thereby the motor-drive pump rotor also is damaged.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of simple in structure, be convenient to keep in repair and the motor-drive pump of safety and reliability.
For achieving the above object, the utility model provides a kind of motor-drive pump, comprise the pump housing, pump housing inner chamber is provided with import and outlet, is provided with sprue between the import of pump housing inner chamber and the outlet, the motor-drive pump rotor is housed on the sprue, the motor-drive pump rotor is provided with rotor blade, and described pump housing inner chamber is provided with filter screen, and described filter screen is positioned at the entrance point of pump housing inner chamber runner, also be provided with the overflow runner on the pump housing inner chamber, on the described overflow runner relief valve be housed.
The beneficial effects of the utility model are: owing to set up the overflow runner at pump housing inner chamber; on the overflow runner, relief valve is housed; so when the oil mass of the pump housing of flowing through is excessive; can alleviate and control the flow velocity and the flow of oil by relief valve; the motor-drive pump rotor is played a protective role, make motor-drive pump work safer reliable, the entrance point at pump housing inner chamber has additional filter screen in addition; can filter out the impurity that is mixed in the oil effectively, guarantee to flow into the quality of oil from import.
The utility model can further be set to described relief valve and comprise relief valve valve seat, spring, the spring door, one end of relief valve valve seat is fastened on the pump housing inner chamber, is arranged with the spring door on the other end of relief valve valve seat, and spring is located between relief valve valve seat and the spring door.
The utility model also can further be set to offer respectively on the described pump housing upper and lower service ports, is equipped with the screw plug nut on the described upper and lower service ports.
Adopt said structure, when the impurity when motor-drive pump needs repairing or in the filter screen was too much, the screw plug nut on the upper and lower service ports of outwarding winding just can be cleared up or be keeped in repair effectively, and was convenient and swift.
The utility model also can further be set to be provided with seal ring between the described screw plug nut and the pump housing.
