Disclosed is a constant flow pump, including a constant flow pump case. A motor support base is fixedly mounted at a top of the constant flow pump case, A drive motor is fixedly mounted at a top of the motor support base. An output end of the drive motor penetrates through the motor support base. A coupling is arranged in the motor support base. A linkage rod is driven by an adjusting hand wheel to enable a connecting plate to move internally. A limiting bump is separated from a slot. A butting seat can be extracted. A rotating shaft and an eccentric cam are detached rapidly. During mounting, the butting seat with a new component is inserted, the limiting bump is in contact with the slot, the adjusting hand wheel is loosened, and a limiting spring enables the bump to be clamped into the slot to accomplish clamping.
A constant flow pump, comprising a constant flow pump case (1), wherein a motor support base (2) is fixedly mounted at a top of the constant flow pump case (1), a drive motor (3) is fixedly mounted at a top of the motor support base (2), an output end of the drive motor (3) penetrates through the motor support base (2), a coupling (4) is arranged in the motor support base (2), a cam shaft mechanism (5) is movably mounted in the constant flow pump case (1), a top of the cam shaft mechanism (5) is fixedly connected to a bottom output end of the drive motor (3) through the coupling (4), a piston mechanism (6) is movably mounted on an outer side of the cam shaft mechanism (5), the piston mechanism (6) coats the outer side of the cam shaft mechanism (5), the piston mechanism (6) is in transmission connection to the cam shaft mechanism (5), one end of the piston mechanism (6) penetrates through the constant flow pump case (1), and a liquid inlet and outlet mechanism (7) is fixedly mounted on a side of the constant flow pump case (1) away from the side penetrated by the piston mechanism (6).
