The invention discloses a plunger type adding pump which solves the problems that in order to meet different filling amounts, a plurality of sets of proportional adjusting rods and lining glands need to be prepared for replacement, operation is inconvenient, and cost is high. The adding pump comprises a shell, a plunger driving mechanism, a filling amount adjusting mechanism and two plunger mechanisms. The plunger driving mechanism comprises a crankshaft and a driving wheel; one end of the crankshaft is used for receiving external power, and a driving wheel is mounted at the other end of the crankshaft and located on a moving path of a piston rod in the plunger mechanism; the filling quantity adjusting mechanism comprises an adjusting part, a rotating shaft and a reducing cam; one end of the rotating shaft is located in the shell, a variable-diameter cam is fixedly installed at the end, the variable-diameter cam is also located on the moving path of a piston rod in the plunger mechanism, and a gap is formed between the variable-diameter cam and the driving wheel; the other end of the rotating shaft is located outside the shell and used for being matched with the adjusting part.
Description
technical field [0001] The invention belongs to the technical field of additive filling, and in particular relates to a plunger type adding pump. Background technique [0002] The additive filling device is composed of a high-precision scraper flowmeter and an additive pump. It uses the scraper flowmeter as the power source to drive the additive pump. When the liquid is transported through the flowmeter, the flowmeter drives the additive pump to work at the same time. The additive is added to the liquid output pipeline according to the set ratio, and then added to the container after being fully mixed, which realizes the online uniform mixing and filling of the additive. [0003] Chinese patent, publication number: CN103527439A, discloses "a filling device", the filling device includes a scraper flowmeter and a plunger-type adding pump directly connected to the scraper flowmeter; the plunger-type adding pump includes a housing The body is a plunger driving mechanism, and tw...
