Problems solved by technology

Since the plunger generates suction when it rises, and generates thrust when it is pressed down, the delivery of liquid will stop during the movement, and constant flow delivery cannot be realized.

Abstract

The invention discloses a double-cylinder type plunger pump with stable output. The fluid inlet of a first oil cylinder communicates with the fluid inlet of a second oil cylinder, and the fluid outletof the first oil cylinder communicates with the fluid outlet of the second oil cylinder; a first motor and a second motor correspondingly drive a plunger of the first oil cylinder and a plunger of the second oil cylinder to move up and down respectively; when the first motor drives the first plunger to move upwards, fluid is sucked into the first oil cylinder, at the same time, the second motor drives the second plunger to move downwards, and the sucked fluid is pushed out of the second oil cylinder; the first plunger of the first oil cylinder interacts with the second plunger of the second oil cylinder in a reciprocating mode to achieve fluid conveying; and the operation speed of the first plunger driven by the first motor is greater than or smaller than the operation speed of the secondplunger driven by the second motor. According to the plunger pump, constant-current conveying of the fluid can be achieved, and the fluid with the large viscosity and the poor fluidity can be furtherstably and continuously conveyed.

Description

technical field [0001] The invention relates to a fluid delivery device, in particular to a device for realizing constant flow delivery for fluids with high viscosity and poor fluidity. Background technique [0002] At present, pneumatic double-diaphragm pumps, gear pumps, peristaltic pumps and single-cylinder plunger pumps are mostly used in fluid delivery devices. In operation, the pneumatic double-diaphragm pump uses compressed air as power to push the plunger of the pump body to move back and forth quickly, thereby generating negative pressure to transmit liquid. Since the movement mode of the pneumatic double-diaphragm pump is fast and uniform, pulses are generated, and constant flow delivery cannot be achieved. And use compressed air as power, the tractive force that forms is less, can't absorb the defective of comparatively viscous liquid. The gear pump adopts two gears whose teeth are constantly engaged to generate negative pressure, thereby generating the ability ...
