Description
The present invention relates to a kind of positive displacement reciprocating compressor and pump, especially a kind of gear change positive displacement reciprocating compressor and pump.
Present known positive displacement reciprocating compressor generally is working medium with gas; The positive displacement reciprocating pump generally is working medium with liquid; They are all by bent axle (handle) linkage mechanism, rotatablely moving of internal-combustion engine, motor become the to-and-fro motion of compressor and pump cylinder inner carrier, make gas or liquid in cylinder body, finish processes such as inspiration, compression, discharge, by advance, the suction and the discharge of valve gate control gas or liquid, and adopting filler to stop gas or leaked liquid, the piston ring on the piston stops gas or the mutual leakage of liquid in the volume of cylinder of two ends.The advantage of this compressor and pump is the pressure height, pressure range is wide, applicability is strong; But that its shortcoming is a discharge capacity is little, flow velocity is low; Bent axle (handle) linkage mechanism complex structure, easily damaged parts is many; The component that the inertial force of crankshaft rotating and connecting rod rotation produce is difficult to balance, and the energy of autophage is big; Pressure, flow produce pulsating nature, in the long-range course of conveying, endanger bigger; So that influence the raising of its efficient, reduce the Economy of working life and use.
The present invention provides a kind of gear change positive displacement reciprocating compressor and pump for the shortcoming that overcomes above-mentioned technology existence.
The object of the present invention is achieved like this: use my patent of invention; The to-and-fro motion and the gear interchange mechanism that rotatablely moves, the patent No.: ZL96117438.2 (being called for short gear change mechanism down) replaces bent axle (handle) linkage mechanism; Cylinder diameter can be selected to design owing to be not subjected to the restriction of crank throw and length of connecting rod by the best fit of volume, pressure, flow, power; Piston need not the shirt rim, can shorten, to increase the cylinder internal volume; The cylinder cap at cylinder body two ends all designs into, the valve door, and reciprocal twice inspiration and discharge working medium is multiplied single chamber volume efficient; Use opposed balance, two single cylinders are formed a unit, or symmetrical balance, four single cylinders are formed a unit, with balance reciprocal inertia force square, improve piston middle pressure (kgf/cm
2) and speed (m/s), a unit, one is back and forth, can make volume and flow (m
3/ min) improve 2～4 times; Cylinder diameter and piston external diameter adopt ceramic and other composite material, make it become unlubricated oil contact, eliminate the hidden danger that is mixed with lubricant oil in the gas; Can increase volume and flow on demand together, can form multistage supercharging, to satisfy the needs of various high pressure operating modes with a plurality of unit permutation and combination.Gear change mechanism can add deceleration, speedup, deceleration and increase the function that square or speedup subtract square, enlarges the scope that power is selected.
The technology of the present invention has following advantage compared with prior art:
1, replaces connecting rod with gear change mechanism, rotatablely moving of power engine become the to-and-fro motion of piston, save self-energy consumption more than 15%; Mechanism is simple, and volume-diminished reduces raw materials consumption more than 30%, and easily damaged parts reduces, and prolong working life, and manufacture cost reduces more than 40%.
2, because cylinder diameter is not subjected to the restriction of crank radius and length of connecting rod, can select design according to conditions such as volume, pressure, discharge capacity and power, improve volume and efficient; Piston need not the shirt rim, can shorten, to improve volume and efficient.
3, single chamber volume efficient is significantly improved.The cylinder cap at cylinder body two ends all designs the valve of inspiration and discharge, and one back and forth, and twice inspiration and discharge working medium significantly improve single chamber volume efficient.
4, make the unit volume improve 2-4 doubly, two opposed combinations of cylinder body, the combination of four cylinder body symmetries can balance reciprocal inertia force and moment of inertia, a unit, one is back and forth, can make volume flow (m
3/ min) improve 2-4 doubly; Fundamentally solve the problem that positive displacement reciprocating compressor and pump displacement are little, flow velocity is low.
5, can unit be made up according to the operating mode needs, multicomputer can be combined, to increase volume flow; Can form the step supercharging, to satisfy the needs of various high pressure operating modes.
6, the positive displacement reciprocating compressor and the pump of gear change, its to-and-fro motion is uniform motion, has fundamentally solved the pulsating nature problem that compressor and pump are discharged gas and liquid.And the gas that has also fundamentally solved compressor causes the Analysis of Pipe Vibrations problem.
7, the pulsating nature of pump instantaneous flow especially, cause the pulsation of liquid communication in suction and the discharge conduit and produce acceleration and inertial force, in preceding half suction stroke, increase the suction resistance of pump, discharge in the stroke at preceding half, increase the discharge resistance of pump, when the pipeline of discharging elongated, when system does not have enough big back pressure, the inertial force of pulsation may cause and sucks and expulsion valve is opened simultaneously, cause liquid directly to rush at the over-current phenomenon avoidance of discharge tube, make pump can not be applicable to the occasion that requires stability of flow by suction pipe; The positive displacement reciprocating pump of gear change mechanism driving has fundamentally solved the stability problem of flow.
8, adopt composite material, solve the oil-free lubrication problem of inboard wall of cylinder block, make not contain lubricant oil in the gas, avoid causing hidden danger such as oil gas blast.
9, the present invention is widely used, in departments such as petrochemical industry, chemical fertilizer industry, oil gas conveying, refrigerating industry, mine mechanism, dynamic power machine, engineering constructions, every script adopts the place of positive displacement reciprocating compressor and pump all can adopt, and uses the present invention to bring huge economic benefit and social benefit for them.
