Problems solved by technology

[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 high-level transmission from small to large. As the highest stress-bearing parts, cranks, connecting rods, and pins become weak links that affect life. Due to the need to meet the strength requirements of large peak stress , many parts are basically made of metal materials, and the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials; these mechanical parts have many types, complex structures, high costs, and low mechanical work efficiency
In the existing public information, we have not found any similar information about the mechanically driven piston acting on the fluid load of the sandwich swing tray piston swing drive machine

Embodiment 1

[0069] The sealing structure between the stationary piston plate 7 or the swinging piston plate 9 and the groove adopts a C-shaped cross-section semi-ring sealing ring 8m, and there is also a group of half-ring sealing rings 8i made of tough material and half-rings between the convex groove of the piston. The combined sealing ring of the ring expansion ring 8j, the C-shaped cross-section semi-ring sealing ring and the combined sealing rings 8i, 8j are all arranged in the convex groove of the half ring of the piston plate 7 or 9 .

[0070] refer to Figure 28 and 29 , as a partial structure embodiment 2 of a detachable piston piece combined with a tray groove;

[0071] The detachable piston piece of oblong outline 29a is shown in the figure, and this detachable piston piece is provided with the protruding ring 39 that is larger than the cross-sectional profile of the tray groove at the joint site combined with the keyway, and the static seal of this detachable piston piece is ...

Embodiment 3

[0072] refer to Figure 30 and 31 , as the partial structure embodiment 3 of the detachable piston sheet combined with the tray groove;

[0073] In the figure, a part of the detachable piston plate with circular contour line 36b is inserted into the tray groove and fixed into a detachable combined structure, insert the joint part of the detachable piston plate on the tray groove and utilize the hole to tighten The firmware 3 is fixed; a static seal is provided between the joint surface of the detachable piston plate and the groove of the tray. The static seals of the detachable piston plate are two static seal half-rings 39b, and two static seal half-ring grooves 39a are provided with depressions along the tangent direction of the center circle of rotation on the detachable piston plate. The sealing half ring 39b is arranged in the static sealing half ring groove 39a; the fastener 3 for the hole is a screw, and the two screws are screwed on the threaded hole 36f of the detac...

Embodiment 6

[0082] The difference between this embodiment and Embodiment 5 is that on the wall of the fixed tray, the center line of rotation is taken as the origin, and the inlet fluid channel 6b is set at half of the outer angle γ, and the interface of the inlet fluid channel 6b is connected to the atmosphere or the outside world , the outer angle γ is greater than the inner angle θ, and γ>θ>γ1 / 2, now the rocking piston plate and the rocking tray are swinging together within the range of the stationary piston plate outer angle γ, and the rest are the same as in Example 5. In this embodiment, on the wall of the fixed tray, the center line of rotation is used as the origin, and the inlet fluid channel 6b is set at a position rotated 180° relative to the hole of the exhaust fluid channel 6a. The internal included angle θ of the plumb normal plane of the piston sheets is 180°. At this time, the two oscillating piston sheets and the swaying tray swing together in the range of the external inc...

Description

technical field [0001] The invention relates to a piston swing driving machine with a mechanically driven piston for pressure-feeding fluid acting on a fluid-loaded pair of swing trays. The swing range of the angular stroke of the swing piston piece is about 0 to 330°, which is suitable for driving the piston to pump the fluid. Work; the fluid that the mechanically driven piston of the driving machine sends 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 high-level transmission from small to large. As the highest stress-bearing parts, cranks, connecting rods, and pins become weak links that affect life. Due to the need to meet the strength requirements of large peak stress , Many parts are basically made of metal materials, and the anti-corrosion performance of metal materials is signifi...
