Description

Two-stage vertical air compressor

Technical field

The utility model relates to a kind of air compressor, particularly relates to a kind of two-stage vertical air compressor.

Background technique

Air compressor is an air pressure generating means the most frequently used in the pneumatic system, and it improves air pressure through compress technique and carries pressurized air through pipeline to gas equipment.Air compressor mainly is divided into piston type air compressor, centrifugal air compressor and screw air compressor, and piston type air compressor is owing to have following advantage: 1, back pressure is stable, and pressure range is big; 2, adaptability is strong, can adapt to any flow, 3, airspeed is low, loss is little, efficient is high, 4, in the general pressure range to the structure material require lower, 5, price is lower, piston type air compressor is that industry is gone up and used maximum air compressors.Piston type air compressor be with piston as extruder member, gas directly be compressed and improve pressure.Generally form by cylinder, piston, bent axle, connecting rod and critical pieces such as suction, outlet valve.Through crankshaft & connecting rotatablely moving of providing of prime mover is converted into the to-and-fro motion of piston, makes the volume generating period property variation between the cylinder and piston, thereby accomplish the processes such as suction, compression and discharge of gas.

Yet; Piston type air compressor will produce great amount of heat in running at present; Its temperature increased with pressure and raises when air was compressed, and too high delivery temperature makes that lubricant oil and piston seal material shift to an earlier date deterioration in the active chamber, even can make and produce carbon deposit in piston ring groove, air valve and the exhaust passage; Cause seizure of piston or passage to stop up, even blast.

Summary of the invention

The purpose of the utility model is that a kind of simple in structure, easy to use, reliable and stable, low cost of manufacture, two-stage vertical air compressor that discharge temperature is lower are provided in order to address the above problem.

The utility model is realized through following technological scheme:

A kind of two-stage vertical air compressor; Comprise compression cylinder, condensed water cooler and motor; Said compression cylinder comprises low-pressure cylinder and high pressure cylinder, and said low-pressure cylinder is provided with first suction port, first air outlet, the first condensed water import and first condensation-water drain, and said high pressure cylinder is provided with second suction port, second air outlet, the second condensed water import and second condensation-water drain; Be provided with first piston in the said low-pressure cylinder; Be equipped with second piston in the said high pressure cylinder, said motor is connected with second piston with first piston respectively, and the said first condensed water import is connected with the said second condensed water import; First air outlet of said low-pressure cylinder is connected with the suction port of said condensed water cooler, and the air outlet of said condensed water cooler is connected with said second suction port.

In air compressor, adopt low-pressure cylinder and high pressure cylinder that air is carried out implements spatial scalable compression simultaneously; In exhaust pressure just as under the situation; Significantly reduced delivery temperature through increasing compression stage; When every stage pressure compared at 3-3.5, as long as two stage compression just can reach the requirement of the exhaust pressure of the required 0.7-0.8MPa of industrial pneumatic system, and exhaust can significantly reduce.The type of cooling between low-pressure cylinder and the high pressure cylinder adopts the condensed water cooler to cool off, and can absorb a large amount of heats that piston type air compressor produces in running effectively.Because the pressurized air that low-pressure cylinder is discharged through the cooling of condensed water cooler, makes the air temperature that gets into high pressure cylinder reduce, thereby reduced the delivery temperature of air compressor.Avoided the too high infringement of temperature to the air compressor internal structure.

Further improvement as the utility model is to be provided with temperature alarm in the said two-stage vertical air compressor.Through in two-stage vertical air compressor, temperature alarm being set; Can detect temperature in the compressor and delivery temperature effectively; When detected temperatures has surpassed the maximum temperature of setting; Alarm sends warning, and the risk of having used air compressor to bring when having avoided temperature too high has ensured personal security and property safety.

Further improvement as the utility model is that said motor adopts the PLC automatic controlling system.Through PLC automatic controlling system motor, when excessive discharge temperature, even unmanned in operation site, the power supply that the PLC automatic control system also can automatic cut-off motor, thus the vertical air compressor is quit work.

The beneficial effect of the utility model is:

In air compressor, adopt low-pressure cylinder and high pressure cylinder that air is carried out implements spatial scalable compression simultaneously; In exhaust pressure just as under the situation; Significantly reduced delivery temperature through increasing compression stage, because the pressurized air that low-pressure cylinder is discharged through the cooling of condensed water cooler, makes the air temperature that gets into high pressure cylinder reduce; Thereby reduced the delivery temperature of air compressor, avoided the too high infringement of temperature the air compressor internal structure.In addition, alarm is set in air compressor, when detected temperatures has surpassed the maximum temperature of setting; Alarm sends warning, and the risk of having used air compressor to bring when having avoided temperature too high adopts the PLC automatic control system that air compressor is controlled; When excessive discharge temperature, though unmanned in operation site, the power supply that the PLC automatic control system also can automatic cut-off motor; Thereby the vertical air compressor is quit work, ensured personal security and property safety.
