Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to an intelligently adjustable hydraulic proportional pump. Background Technology

[0002] Currently, proportional pumps on the market are divided into two types according to their transmission principle: pneumatic proportional pumps and hydraulic proportional pumps. Hydraulic proportional pumps are mainly imported equipment, with relatively few domestically produced products.

[0003] Hydraulic proportional pumps work by precisely delivering two-component substances at a fixed ratio (usually 1:1), ensuring stable flow rates before mixing and instantaneous film formation after mixing. They mainly consist of a pump body, piston or plunger, valves, seals, and a drive unit. Material ratios are typically 1:1 (from 0% to 100%) or 1:2, 1:3, or other fixed ratios. However, different component ratios are required for different media spraying in chemical production, and currently, there are no adjustable proportional pumps available on the market.

[0009] To facilitate the recycling of hydraulic oil, the first hydraulic cylinder preferably has a first oil inlet and a first oil return port fixedly installed on its outer side.

[0010] To facilitate the recycling of hydraulic oil, the intelligently adjustable hydraulic proportional pump of this invention preferably has a second oil inlet and a second oil return port fixedly installed on the outer side of the second hydraulic cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the proportions of different components can be adjusted by controlling the corresponding first and second hydraulic cylinders through the first and second servo proportional valves. By designing an adjustable proportional pump, the spraying ratio can be adjusted in a timely manner without replacing the lower cylinder of the pump. The pump ratio can be adjusted in real time from 1:1 to 10:1 and more. One device can perform spraying work on different media, saving costs. Attached Figure Description
