Problems solved by technology

The force used by the crankshaft gradually decreases from the maximum (0°~180°). Due to the uneven speed and force distance, the mechanical efficiency is reduced, so it is generally only suitable for gas compression.

Abstract

The invention relates to a rolling lever type piston pump, which comprises a support (12), a cylinder block (8), pistons (10), a valve seat (11), a roller seat (6), a plurality of levers (4), a link rod (9), a contact roller (1), a pressure roller (2) and an idler (3). The cylinder block (8) is fixedly mounted on the support (12); in the cylinder block (8), a plurality of piston cavities are provided, in each of piston cavity, a piston (10) is provided; the valve seat (11) is fixedly mounted in the inner hole of the cylinder block (8); the roller seat (6) is fixedly looped on the outer edge of the cylinder block (8); in the middle of the edge of the roller seat (6) and along the periphery, a plurality of lever-installing slots are arranged in equi-spaced way; the levers (4) are arranged in the lever-installing slots; the levers (4) are hinged with the link rod (9), which is hinged with the pistons (10); the contact roller (1) is looped on the periphery of the roller seat (6); the pressure roller (2) and the idler (3) are axially arranged on the inner ring of the contact roller (1), wherein, the middle of the pressure roller (2) contacts with the levers (4) and the outer edge of the roller seat (6), the left and the right edge of the pressure roller (2) contact with the outer edge of the roller seat (6). The invention enables the piston to move evenly, and is applicable for the compression of gas and liquid.

Description

Technical field: [0001] The invention relates to a piston pump. Mainly used for air and liquid compression. Background technique: [0002] Pumps used for air and liquid compression require high pressure, low noise, continuous operation, long service life, large flow and high efficiency. The general piston pump completes the reciprocating motion of the piston through the crankshaft connecting rod mechanism (air compressor). When the crankshaft rotates from 0° to 90°, the speed of the piston moves from the minimum to the maximum, so the speed of the piston is uneven. The force used by the crankshaft gradually decreases from the maximum (0°~180°). Due to the uneven speed and force distance, the mechanical efficiency is reduced, so it is generally only suitable for gas compression. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages and provide a rolling lever piston pump which can make the moving speed of ...
