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 plunger pump with stable output. The fluid inlets of the first oil cylinder and the second oil cylinder are connected, and the fluid outlets of the first oil cylinder and the second oil cylinder are connected; the first and second motors respectively drive the second The plungers of the first and second oil cylinders move up and down. When the first motor drives the first plunger to move upward to suck the fluid into the first oil cylinder, the second motor drives the second plunger to move downward to push the sucked fluid out of the second oil cylinder; the first plunger of the first oil cylinder and the first oil cylinder The second plunger of the second oil cylinder reciprocates alternately to realize the delivery of fluid. And the running speed at which the first motor drives the first plunger is greater than or lower than the running speed at which the second motor drives the second plunger. The device can not only realize the constant flow delivery of the fluid, but also can further realize the stable and continuous delivery of the fluid with high viscosity and poor fluidity.

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 ...
