用强制办法控制阀的行程,可以提高活塞式压缩机的速度,降低阀的损失,提高阀的可靠性和寿命。以液压传动作为阀的控制系统为最有前途。压缩机的工作特性不允许盲目模仿强制配气系统,例如发动机的配气系统。在苏联根据ГOCT6492-64生产了沸点由+10到-30℃、冷凝点在+50℃以下的一级氟冷剂压缩机和沸点由+5到-30℃、冷凝点在+40℃以下的氨气压缩机。因此,当压缩机工作状况改变时,阀的开启时间也应该改变。这种情况在活塞式压缩机的强制气体分配系统结构中已做了考虑〔2〕。在各种型式的强制传动装置中,液压传动
With the mandatory approach to control the valve stroke, you can increase the speed of the piston compressor to reduce the valve loss and improve valve reliability and life. The hydraulic transmission as the valve control system for the most promising. Compressor operating characteristics do not allow blind imitation of forced air distribution systems, such as engine air distribution systems. According to ГOCT6492-64 in the USSR a primary refrigerant compressor with a boiling point from +10 to -30 ° C and a condensation point below +50 ° C and a primary refrigerant compressor with a boiling point from +5 to -30 ° C and a condensation point below +40 ° C Ammonia compressor. Therefore, when the compressor operating conditions change, the valve opening time should be changed. This situation has been considered in the compulsory gas distribution system structure of the piston compressor [2]. In all types of forced transmission, hydraulic transmission
