我部有几台氨压缩机,它的能量调节完全采用手动操作。为了在原有设备的基础上,实现空调制冷系统的自动控制,我们对6Aw10型氨压缩机的能量调节装置进行了改进,使它既能手动,也能自动。经过长期运行性能良好,工作稳定.一、能量调节原理1.自动控制如图1所示,能量调节阀手柄扳到氨压缩机一组位置(即图1A 位置),油路分配器的手柄扳到自动位置(即图1油路分配器缺口位置)。当氨压缩机投入运行后,曲轴箱里的冷冻机油经油泵加压,一部分油经能量调节阀 A 管道流经油路分配器的一个缺口,再从它分别流向三个三通电磁阀和油压继电器,当三通电磁阀都打开时,冷冻机油又经油路分
My department has several ammonia compressor, its energy regulation completely manual operation. In order to realize the automatic control of the air conditioning and refrigeration system on the basis of the original equipment, we improved the energy conditioner of the 6Aw10 ammonia compressor to make it both manual and automatic. After long-term performance and good performance, stable work. First, the principle of energy regulation 1. Automatic control shown in Figure 1, the energy regulator valve handle to a group of ammonia compressor position (Figure 1A position), the oil distributor handle pull To the automatic position (ie, Figure 1, the oil distributor gap position). When the ammonia compressor is put into operation, the freezer oil in the crankcase is pressurized by the oil pump. A part of the oil flows through a pipe of the energy regulating valve A through a gap of the oil distributor and flows from it to three three-way solenoid valves and oil Pressure relay, when the three-way solenoid valve are open, the oil again by the oil refrigeration points
