Description

Compressor open system

Technical Field

The utility model belongs to the technical field of compressors, and particularly relates to an open system of a compressor.

Background

The gas circuit schematic diagram of the existing compressor open system is shown in fig. 3, wherein a one-way valve is arranged in the two-position four-way valve, the one-way valve has the function of preventing high-pressure gas from flowing back to the two-stage pump when the compressor is not in operation, and because the electromagnetic valve is arranged at the rear end of the gas storage tank and each gas utilization unit, the electromagnetic valve is in a closed state when the electromagnetic valve is not in operation, and therefore the high-pressure gas cannot flow from the gas storage tank and the gas utilization units to the two-stage pump.

The functional principle of the existing compressor open system is as follows:

a. the compressor charges the gas using unit 2 and the gas storage tank 13:

The humid gas in the external environment is compressed through the air inlet/outlet 17 by the two-stage pump 3, the compressed high-pressure gas is filtered by the dryer 4, and then the moisture in the high-pressure gas is inflated to the air utilization unit 2 and the air storage tank 13 through the one-way valve in the two-position four-way valve 18, as shown by the arrow in fig. 7.

B. the gas unit and the gas storage tank are used for exhausting to the atmosphere:

For example: the air unit is used for exhausting to the atmosphere: firstly, the electromagnetic valve 6 and the electromagnetic valve 8 are opened, dry high-pressure gas in the gas unit passes through the electromagnetic valve 8, and a part of dry high-pressure gas acts on the upper end of the two-position four-way valve 18 through the electromagnetic valve 6 to overcome spring force so as to open the two-position four-way valve 18; a portion of the dried high pressure gas will pass through the open two-position four-way valve 18 and reversely pass through the dryer 4 while the dried high pressure gas absorbs moisture in the dryer 4, and then flow through the open two-position four-way valve 18 to the air inlet/outlet 17 to be discharged to the atmosphere, and when the gas pressure in the gas using unit is 1.5±0.75bar, the pressure through the electromagnetic valve 6 is insufficient to open the two-position four-way valve 18, and the air discharge is stopped as shown in fig. 8.

C. the air storage tank rapidly charges the air utilization unit:

The high-pressure gas in the gas storage tank 13 passes through the electromagnetic valve 7 and directly enters the secondary cavity in the two-stage pump 3 (the primary compression process is omitted, the inflation efficiency is improved), and the compressed high-pressure gas passes through the dryer 4 and then passes through the two-position four-way valve 18 to be rapidly inflated to the gas utilization unit, as shown in fig. 9.

Because one-way valve exists in the two-position four-way valve, the one-way valve is required to be jacked to charge the air using unit and the air storage tank, and the process of jacking the one-way valve consumes high-pressure air energy; and the two-position four-way valve has the advantages of more parts and higher part precision requirement, and increases the part cost.

Through the above analysis, the problems and defects existing in the prior art are as follows: the existing compressor open system adopts a two-position four-way valve, the one-way valve is required to be jacked up to charge air to the air utilization unit and the air storage tank, and the high-pressure air energy is consumed in the process of jacking up the one-way valve; and the two-position four-way valve has the advantages of more parts and higher part precision requirement, and increases the part cost.

In one embodiment, two ends of the plurality of gas utilization units are respectively communicated with a gas storage tank and a pressure sensor, and the gas storage tank is communicated with the bipolar pump through a second electromagnetic valve.

By combining all the technical schemes, the utility model has the advantages and positive effects that: the number of parts, the precision of the parts and the cost of the parts in the two-position two-way valve are greatly reduced relative to those of the two-position four-way valve, and the two-position four-way valve in the existing compressor open system is replaced by the two-position two-way valve, so that the performance is obviously improved on the premise of ensuring that the original functions are not changed, the material cost is reduced, and the manufacturing precision is lower.

The utility model can set the forms of the air inlet and the air outlet according to the requirements on noise: if no noise is required, the air inlet and the air outlet can be combined together and separated; if required, the noise mainly occurs in the process of exhausting the air from the air utilization unit to the atmosphere in a separated mode, if the noise is adopted, a silencer needs to be added at the air inlet/outlet when the noise is combined, when the compressor charges the air utilization unit, the silencer is added, the resistance increasing process in the air suction process exists, the air suction flow is influenced, and when the noise is added at the air outlet in a separated mode, the performance is not influenced. The functions of the compressor for inflating the air utilization unit and the air storage tank, exhausting air from the air utilization unit and the air storage tank to the atmosphere, quickly inflating the air utilization unit from the air storage tank and the like can be realized.

The outer end of the exhaust port 15 is provided with a muffler.

An electromagnetic valve is arranged between each gas utilization unit 2 and the output pipeline. The two ends of the plurality of air utilization units 2 are respectively communicated with an air storage tank 13 and a pressure sensor 14, and the air storage tank 13 is communicated with the bipolar pump 3 through a second electromagnetic valve 7.
