Cast Iron Hand Pumps

At present, most of the manual pumps adopt double plunger design, with low pressure output and high pressure output, but when the pressure pump is in high pressure output, the flow is too small and the work efficiency is low. Taking mine hand pump as an example, the specific parameters are as follows: rated pressure (high pressure) 63 MPa; rated output flow 1.5 ml / time; low pressure output pressure 5-10 MPa; low pressure theoretical flow 12 ml / time; hydraulic oil tank capacity 2 L; maximum handle force not more than 350 n, high pressure plunger diameter 10.5 mm, low pressure plunger diameter 28 mm. In the pressure range of 10-20Mpa, the handle force of manual pump is only 45-90n, which is far lower than the specified 350n, and its efficiency is less than 30% of the rated efficiency.
