Abstract
The invention discloses a liquid piston compressor, which comprises a cylinder, pressure transmission liquid, a pump, a check valve, a buoyancy check valve, a selector valve, a lever and a transmission mechanism; the liquid piston compressor adopts the pump to drive the liquid to rise or drop in the cylinder, so that the conventional piston movement is replaced for realizing the suction and the exhaust of the cylinder; as the friction between the liquid piston and the cylinder wall is much smaller than the friction of a solid piston against the cylinder wall, the efficiency is improved and the service life is prolonged; besides, the liquid piston and the cylinder can be fabricated to be a parallel structure with a plurality of tiny pipes, so that the problem in the conventional cylinder that heat dissipation is difficult to carry out due to high cylinder diameter is solved; and the production cost is lower.
Description
Affiliated technical field
The present invention relates to a kind of positive displacement compressor, belong to the Compressor Technology field.
Background technique
Positive displacement compressor generally adopts piston type at present, and this piston compressor makes it efficient and reduces owing to the friction of piston and cylinder wall, and the life-span is shorter, and is difficult to heat radiation when cylinder bore is big.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of liquid piston compressor, this liquid piston compressor utilizes pump to drive the liquid traditional piston of replacement that rises or descend in cylinder and moves to realize the air-breathing and exhaust of cylinder, because the frictional ratio solid piston of liquid piston and cylinder wall and the friction of cylinder wall are much smaller, efficient and life-span have so just been improved, liquid piston and cylinder can be made many tubule parallel-connection structures in addition, solved the difficult problem that traditional cylinder bore is difficult to dispel the heat when big, and apparatus cost is lower.
Structure of the present invention comprises cylinder, accommodating pressure-transmitting liquid, pump, one-way valve, buoyancy safety check, selector valve, lever and driving mechanism.Described cylinder places the lever two ends respectively, lever links to each other with selector valve by driving mechanism such as gear etc., and accommodating pressure-transmitting liquid such as water, wet goods are housed in the cylinder, and cylinder head is communicated with suction port by one-way valve, be communicated with relief opening by the buoyancy safety check, cylinder bottom is communicated with pump by selector valve.
The invention has the beneficial effects as follows, adopt liquid piston to solve the friction and wear of piston and cylinder wall, so just improved efficient and life-span, liquid piston and cylinder can be made many tubule parallel-connection structures, solved the difficult problem that traditional cylinder bore is difficult to dispel the heat when big, and apparatus cost is lower.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is another kind of example structure schematic representation of the present invention.
1. relief openings among the figure, 2. suction port, 3. buoyancy safety check, 4. breather check valve, 5. cylinder, 6. lever, 7. positioning hole, 8. positioning bead, 9. positioning hole, 10. driving mechanism, 11 pumps, 12 selector valves, 13 cylinders, 14 breather check valves, 15 buoyancy safety check.
Embodiment
In Fig. 1, cylinder (5) and cylinder (13) place lever (6) two ends respectively, lever (6) can many parallel configuration to increase the stability of a system, lever (6) links to each other with selector valve (12) by driving mechanism (10), positioning bead (8) is arranged on the lever (6), and the hole corresponding with positioning bead (8) is respectively positioning hole (7) and positioning hole (9).Cylinder is equipped with accommodating pressure-transmitting liquid in (5), and cylinder (5) top is communicated with suction port (2) by breather check valve (4), is communicated with relief opening (1) by buoyancy safety check (3), and cylinder (5) bottom is communicated with pump (11) by selector valve (12).Cylinder is equipped with accommodating pressure-transmitting liquid in (13), and cylinder (13) top is communicated with suction port (2) by breather check valve (14), is communicated with relief opening (1) by buoyancy safety check (15), and cylinder (13) bottom is communicated with pump (11) by selector valve (12).
Buoyancy safety check (3) and buoyancy safety check (15) are floatable hollow or lightweight stoppers in accommodating pressure-transmitting liquid, because the accommodating pressure-transmitting liquid liquid level is difficult to control accurately, when the release liquid level rises to the cylinder top, have small amount of liquid and overflow cylinder, at this moment the buoyancy safety check floats, and is back to cylinder with the liquid that guarantees to overflow when inspiratory cycle begins.
During work, startup pump (11) is extracted into cylinder (13) lining with the accommodating pressure-transmitting liquid of cylinder (5) lining, at this moment the breather check valve (4) at cylinder (5) top is opened, buoyancy safety check (3) cuts out, carry out air-breathing, the buoyancy safety check (15) at cylinder (13) top is opened, and breather check valve (14) is closed, and carries out exhaust.By the time cylinder (5) is filled gas, cylinder (13) is when having arranged gas, cylinder (13) weight of topping up fully makes positioning bead (8) disengaging positioning hole (7) slide to positioning hole (9), the rotation of lever (6) drives selector valve (12) by driving mechanism (10) and commutates, at this moment pump (11) is extracted into cylinder (5) lining with the accommodating pressure-transmitting liquid of cylinder (13) lining, the breather check valve (14) at cylinder (13) top is opened, buoyancy safety check (15) cuts out, carry out air-breathing, the buoyancy safety check (3) at cylinder (5) top is opened, breather check valve (4) is closed, and carries out exhaust.Cylinder (5) and cylinder (13) hocket air-breathing and exhaust like this, make relief opening (1) continuous exhaust pneumatic wallop, and suction port (2) air inlet continuously forms continuous compression work.
Fig. 2 is another kind of embodiment, and its difference is that cylinder (5) and cylinder (13) constitute by many tubules, and this structure has increased the heat exchange area of cylinder with the external world, thereby can dispel the heat better.
