Abstract
The utility model discloses a compressor cylinder, which is provided with a balance section and can prolong service life of packing inside. The compressor cylinder comprises a cylinder body and a cylinder cavity disposed in the cylinder body, the cylinder cavity is provided with a working section and the balance section which are separated by a piston, a working cavity used for air intake and air exhaust is arranged on the cylinder body and communicated with the working section, and a buffer cavity arranged on the cylinder body is respectively communicated with an air outlet of the working cavity and the balance section. The buffer cavity arranged in the cylinder increases volume of the balance section and can effectively buffer airflow pulsation in a pipeline of the balance section, thereby reducing air temperature, prolonging service life of packing in the cylinder and reducing energy consumption. Further, as the shape and the size of the buffer cavity are equal to those of the working cavity, the cylinder has blank exchangeability and universality with a differential cylinder or a double-action cylinder. The utility model is particularly suitable to be popularized and applied to cylinders for gas filling stations.
Description
Technical field
The utility model relates to a kind of compresser cylinder, especially relates to a kind of compresser cylinder with balancing segment.
Background technique
At present, the form that compressor band balancing segment cylinder all adopts balancing segment directly to communicate with the cylinder working chamber air outlet by pipeline, because no surge volume in the balancing segment, piston moves back and forth in cylinder at high speed, thereby cause frequently vibration back and forth of gas in the equalizing main, pressure surge is big, temperature is high, power consumption increases, and especially compressor packing can reduce in this abominable operating conditions following working life greatly.The user if need transform down this kind band balancing segment structure cylinder as differential cylinder or double-acting cylinder structure, can only change entire cylinder and can realize when transforming product in addition.
The model utility content
Technical problem to be solved in the utility model provides a kind of interior filler of cylinder compresser cylinder in working life that improves.
The technological scheme that its technical problem that solves the utility model adopts is: compresser cylinder, the cylinder cavity that comprises cylinder body and be positioned at cylinder body, the cylinder cavity has active section and the balancing segment that is separated by piston, cylinder body is provided with and is used for air inlet and the active chamber of giving vent to anger, and active chamber communicates with active section, cylinder body is provided with buffer cavity, and buffer cavity communicates with the air outlet and the balancing segment of active chamber respectively.
Further be the shape of described buffer cavity, big or small suitable with active chamber.
Further be, the outer end of buffer cavity extends to the outer surface of cylinder body, and cylinder body is provided with and is positioned at buffer cavity outer end sealing cover.
Further be that buffer cavity is arranged on the sealing cover with the gas port that the active chamber air outlet communicates.
Further be that buffer cavity is arranged on the cylinder body with the gas port that the active chamber air outlet communicates.
The beneficial effects of the utility model are: the buffer cavity of setting has increased the volume of balancing segment, the effectively gas in the cushioning balance segment pipe, thereby can reduce gas temperature, improve in the cylinder filler working life with cut down the consumption of energy; And shape, the size of buffer cavity are made suitable with active chamber, and make cylinder of the present utility model and differential cylinder or double-acting cylinder have blank interchangeability and versatility, be particluarly suitable for gas station with promoting the use of above the cylinder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: cylinder body 1, buffer cavity 2, balancing segment 3, active chamber 4, sealing cover 5, active section 6.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, compresser cylinder of the present utility model, the cylinder cavity that comprises cylinder body 1 and be positioned at cylinder body 1, the cylinder cavity has the active section 6 and balancing segment 3 that is separated by piston, cylinder body 1 is provided with and is used for air inlet and the active chamber 4 of giving vent to anger, and active chamber 4 communicates with active section 6, and cylinder body 1 is provided with buffer cavity 2, and buffer cavity 2 communicates with the air outlet and the balancing segment 3 of active chamber 4 respectively.In Fig. 1, active chamber 4 can be from the left air inlet, right-hand giving vent to anger; Also can be from right-hand air inlet, left is given vent to anger.During cylinder operation, descent of piston, the cylinder cavity volume increases, and the air pressure of active chamber 4 suction ports is higher than the air pressure in the active section 6, and active chamber 4 suction port air valves are opened, gas is entered in the active section 6, piston stroking upward makes that the air pressure in the active section 6 raises then, makes that the gas after overcompression becomes pressurized gas, when the air pressure in the active section 6 was higher than the pressure of active chamber 4 air outlets, the air valve of active chamber 4 air outlets was opened.At this moment, be the pressure of balance active section 6, the cooled pressurized gas of compression need be passed in the balancing segment 3 with balancing segment 3.By the buffer cavity 2 that is provided with, the pressurized gas after the compression enter in the buffer cavity 2 by pipeline from the air outlet of active chamber 4, enter again in the balancing segment 3, thereby balance the pressure of active section 6 with balancing segment 3, reduce the resistance to motion of piston.And this buffer cavity 2 has increased the volume of balancing segment 3, the effectively gas in cushioning balance section 3 pipelines, thereby can reduce gas temperature, improve in the cylinder filler working life with cut down the consumption of energy.
In the above-described embodiment, buffer cavity 2 can be made structure shape arbitrarily, as long as can effectively increase the volume of balancing segment 3, in order to reach the purpose that has blank interchangeability and versatility with differential cylinder or double-acting cylinder, as mode of priority, the shape of described buffer cavity 2, big or small suitable with active chamber 4.Like this, can realize the interchangeability of buffer cavity 2 and active chamber 4.
For ease of the processing of buffer cavity 2, the outer end of buffer cavity 2 extends to the outer surface of cylinder body 1, and cylinder body 1 is provided with and is positioned at buffer cavity 2 outer end sealing covers 5.Because the outer end of buffer cavity 2 extends to the outer surface of cylinder body 1, then add and can directly on cylinder body 1, process the through hole that communicates with the cylinder cavity man-hour and get final product, be beneficial to the machining making; After processing through hole, this through hole sealing back is formed buffer cavity 2 by the sealing cover 5 that is provided with on the cylinder body 1.
And when communicating with buffer cavity 2 in active chamber 4 air outlets, the gas port of buffer cavity 2 can be arranged on the sealing cover 5 or cylinder body 1, all can the pressurized gas in the active section 6 be passed in the balancing segment 3 fine realization.In Fig. 1, buffer cavity 2 is arranged on the cylinder body 1 with the gas port that active chamber 4 air outlets communicate.
