Abstract

A tray piston type rocking fluid pressure-feeder driven by a crank connecting rod mechanism comprises a support housing (5), a plurality of tray piston type rocking execution devices (2), a fluid inlet and outlet passage system, a cooling system, and a driving force generation system. The fluid inlet and outlet passage system comprises a fluid passage (6, 6a, 6b), a pipe orifice and a valve. The fluid passage (6, 6a, 6b) is in communication with a working chamber (4c). The cooling system is a mechanism for forced cooling and / or natural heat dissipation of components of the fluid pressure-feeder. The support housing (5) is provided with n (n≥1) tray piston type rocking execution devices (2), rotating centerlines of rocking trays (36) of the n tray piston type rocking execution devices (2) are distributed on the same circumferential diameter around the rotating center of a driving crankshaft (10), and the rotating centerlines of the rocking trays (36) are perpendicular to a plane of a support wallboard (34). A system for mechanically driving pistons to act on a fluid load comprises a prime motor and a crank rocker mechanism. The reciprocating rocking range of an angular travel of rocking piston plates (40) is approximately 0 to 150 degrees, and the fluid pressure-feeder is applied to driving the pistons to pressure-feed a fluid for pumping work; and the pressure-fed fluid is gas or liquid.

Description

technical field [0001] The invention relates to a pallet-piston oscillating pressure-feeding fluid machine driven by a crank-connecting rod mechanism. The reciprocating swing range of the oscillating piston piece angular stroke is about 0-150°, which is suitable for driving the piston to pressure-feed fluid for pumping work; the pressure-feeding fluid The fluid that the motor drives the piston to press is gas or liquid. Background technique [0002] There are centrifugal pumps, plunger pumps and piston compressors in the existing disclosed pressure-feeding fluid machines. The stress intensity occurring in the dynamic process presents a higher-level peak-to-valley value change from small to large. As the highest stress-bearing parts, the connecting rod and the pin on the piston become the weak link that affects the life. In addition, due to the need to meet the large The strength requirements of the peak stress, many parts are basically made of metal materials, and the anti-...
