Abstract

The utility model relates to a volume-type hydraulic driving reciprocating compressor comprising air cylinders (3 and13) and a hydraulic cylinder (9). The utility model is characterized in that the two air cylinders (3 and 13) are concentrically connected with the hydraulic cylinder (9) through a connector (5); the air cylinders (3 and 13) share a piston rod (4) with the hydraulic cylinder (9); a piston (7) of the hydraulic cylinder is arranged in middle part of the piston rod (4); the pistons (2 and 12) of the air cylinders are respectively connected with two ends of the piston rod (4); a guide sleeve (11) is arranged between the connector (5) and the piston rod (4). After being used, the compressor can obviously reduce noise and vibration of the device in running process, decrease the starting pressure of the device, simplify the whole design structure of the device and improve the efficacy.

Description

Positive displacement hydraulic-drive reciprocating compressor
Technical field
The utility model relates to a kind of positive displacement hydraulic-drive reciprocating compressor.
Background technique
Disclosures in Italian patent application people Sa Nalini. not Netac has applied for patent of invention " positive displacement hydraulic-drive reciprocating compressor " in 1986 in China, and this number of patent application is: 86100929.The problem that former technology exists mainly shows:
1, there is certain impact shock in oil hydraulic cylinder in the to-and-fro motion process, produces the loosening phenomenon of noise and link.
2, the changement design is complicated, the rate of fault height, and maintenance difficulty is bigger.
3, during the cylinder pressurized gas, the compression of rodless cavity one-level; The compression of rod chamber secondary makes that air displacement is little under the same power.
Summary of the invention
The purpose of this utility model is in order to solve the deficiencies in the prior art, provide a kind of only at positive displacement hydraulic-drive reciprocating compressor and the vibration and the noise of minimizing equipment in running, reduce the wearing and tearing of breakout pressure and Sealing, the simplified structure design, the positive displacement hydraulic-drive reciprocating compressor of raising effect.
Technical solution of the present utility model is:
This positive displacement hydraulic-drive reciprocating compressor comprises cylinder and oil hydraulic cylinder, it mainly is to connect an oil hydraulic cylinder with one heart by connector between two cylinders, the shared piston rod of cylinder and oil hydraulic cylinder, hydraulic cylinder piston is loaded on the piston rod middle part, and cylinder piston is connected to the two ends of piston rod, is provided with guide sleeve between connector and piston rod.
Further technical solution of the present utility model is:
On the end cap at two cylinder two ends, be respectively equipped with intakeport, on two connectors, also be respectively equipped with intakeport.
On oil hydraulic cylinder, also connect the damping device that constitutes by one-way throttle valve and oil pipe.
Be fixed with explosion-proof sensor on the wall of oil hydraulic cylinder, direction selecting controller is connected between two explosion-proof sensors.
Said four intakepories and communicate with two cylinders respectively with the relief opening of intakeport radial symmetric setting.
Said oil hydraulic cylinder, cylinder, connector, end cap are fixed as one by the pull bar cross-under.
The technique effect that the utility model produced is:
Increased the throttling Cushioning Design at the oil hydraulic cylinder two ends, can reduce the impact of hydraulic cylinder piston oil hydraulic cylinder two ends guide sleeve.Oil hydraulic cylinder is very little at the impact shock that the to-and-fro motion process exists, and noise is also little, and link is difficult for loosening.The explosion-proof detector of oil hydraulic cylinder two ends design can extract commutation signal and realize control, can simplify the changement design, and rate of fault is low, and maintenance difficulty is less.The cylinder compression adopts rodless cavity, rod chamber to be the one-level compression simultaneously, and the one-level compression reaches the exhaust pressure requirement, improves compression horsepower.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, this compressor has two cylinders 3,13, connects 3,13 and oil hydraulic cylinders of 9, two cylinders of an oil hydraulic cylinder, 9 shared piston rods 4 again with one heart by two connectors 5 between these two cylinders 3,13.The middle part of piston rod 4 is provided with hydraulic cylinder piston 7, and the two ends of piston rod 4 respectively are provided with a cylinder piston 2,12.Between connector 5 and piston rod 4, also be provided with guide sleeve 11 with piston rod 4 sliding contacts.Be fixedly connected with end cap 14 on the termination of cylinder 3,13, end cap 14 is provided with intakeport 1a, 1d again, and these two intakeport 1a, 1d are communicated with cylinder 3,13.On oil hydraulic cylinder 9, also be provided with two damping devices that constitute by one-way throttle valve 8 and oil pipe 10, the diameter of communicate with each root oil pipe 10 two buffering hydraulic fluid ports small one and large one, generation buffer function when the fluid that is entered by oil inlet and outlet 6 is under pressure.The intakeport 1b, the 1c that are fixed on the connector 5 communicate with cylinder 3,13 respectively.Be installed with two explosion-proof sensors 15 on oil hydraulic cylinder 9 walls, direction selecting controller 16 is connected between the explosion-proof sensor 15.
On end cap 14 and connector 5 with also corresponding respectively relief opening 1e, 1f, 1g, the 1h of being provided with in the radial symmetric position of intakeport 1a, 1b, 1c, 1d.
Said end cap 14, connector 5, cylinder 3,13 and oil hydraulic cylinder 9 are fixed as a compressor integral body by pull bar 17.
Under piston rod 4 reciprocating drivings, two ends cylinder piston 2,12 is simultaneously reciprocating, makes the rod chamber of cylinder 3,13 and rodless cavity repeat air-breathing and exhaust work respectively.When hydraulic cylinder piston 7 move to oil hydraulic cylinder 9 damping devices two the buffering hydraulic fluid ports between the time, hydraulic cylinder piston 7 is moved into buffer status, when piston 7 end faces arrive explosion-proof sensor 15 centers, sensor 15 obtains signal feed back and gives direction selecting controller 16, direction selecting controller 16 will send the commutation instruction, and piston rod 4 carries out counteragent again.
