Reciprocating compressor stepless gas amount regulating system used for explosive gas area

应用于爆炸性气体区域的往复压缩机无级气量调节系统

Abstract

本发明公开了一种往复式压缩机排气量无级调节系统。系统组成包括防爆液压油站、液压分配器、伺服电机、伺服电机减速箱、卸荷器、防爆控制箱、传感器和曲轴编码器等组成。加装此系统使大型往复压缩机排气量能无级连续调节,同时使压缩机耗电量随排气量减少而减少。在压缩机运行过程中,分配器始终严格保持1/2转速与往复压缩机同步旋转,从油站输出的高压液压油经液压分配器作用后生成一周期性压力脉冲波。此压力脉冲波的周期时长同压缩机旋转周期相同,每个周期的起点在往复式压缩机压缩行程之前,且压力作用时间压力脉冲宽度是可调的。此调节系统采用了防爆设计,能够在爆炸性气体区域(防爆等级:EExd II CT4)使用的往复式压缩机上应用。
The invention discloses a displacement stepless regulation system of a reciprocating compressor. The system comprises an explosion-proof hydraulic oil station, a hydraulic distributor, a servo motor, a reduction gearbox of the servo motor, an unloader, an explosion-proof control box, a sensor, a crankshaft encoder, etc. With the system added, the air displacement of the large reciprocating compressor can be regulated steplessly and continuously. At the same time, the electricity consumption of the compressor is reduced with the reduction of the air displacement. In the operation process of the compressor, the distributor always maintains one half of speed strictly and rotates synchronously with the reciprocating compressor. A periodic pressure pulse wave generates from high pressure hydraulic oil output from the oil station after the effect of the hydraulic distributor. The cycle length of the pressure pulse wave is the same with the rotary period of the compressor. The starting point of every period is before the compressing stroke of the reciprocating compressor and the pressure effect time and the pressure pulse width can be regulated. With the explosion-proof design adopted, the regulation system can be applied to the reciprocating compressor that is used in an explosive gas area (explosion-proof class: EExd II CT4).
