Description
技术领域 technical field
本实用新型涉及一种真空泵系统，具体涉及一种节能真空泵系统。 The utility model relates to a vacuum pump system, in particular to an energy-saving vacuum pump system.
背景技术 Background technique
传统的真空泵系统，在对真空箱进行抽真空后，会断开真空泵和真空箱的连接。真空泵在断开与真空箱的连接后会继续工作，此时由于真空泵的吸气端没有空气进入，真空泵的吸气端与真空泵的排气端之间的压力差很大，导致真空泵在高功率下工作，功耗很大。 In a conventional vacuum pump system, the connection between the vacuum pump and the vacuum box will be disconnected after the vacuum box is evacuated. The vacuum pump will continue to work after it is disconnected from the vacuum box. At this time, because there is no air entering the suction end of the vacuum pump, the pressure difference between the suction end of the vacuum pump and the exhaust end of the vacuum pump is very large, resulting in the vacuum pump operating at high power. Under the work, the power consumption is very large.

如图1所示，节能真空泵系统，它包括真空泵1、控制阀一2、控制阀二3、真空箱4和管路5，控制阀一2的进气端通过管路5与真空箱4连接，控制阀一2的出气端通过管路5与真空泵1的吸气端连接，控制阀二3的进气端通过管路5与真空泵1的排气端连接，控制阀二3的出气端通过管路5与真空泵1的吸气端连接；它还包括单向止回阀6，单向止回阀6的进气端通过管路5同时与真空泵1的排气端和控制阀二3的进气端连接；它还包括三个气压传感器7和控制器8，真空箱4内部、真空泵1的吸气端和真空泵1的排气端分别设置有气压传感器7，气压传感器7、控制阀一2和控制阀二3分别通过导线与控制器8连接。单向止回阀6的出气端通过管路5与消音器9连接。 As shown in Figure 1, the energy-saving vacuum pump system includes a vacuum pump 1, a control valve 2, a control valve 3, a vacuum box 4 and a pipeline 5, and the intake end of the control valve 12 is connected to the vacuum box 4 through the pipeline 5 , the outlet end of control valve one 2 is connected to the suction end of vacuum pump 1 through pipeline 5, the inlet end of control valve two 3 is connected to the exhaust end of vacuum pump 1 through pipeline 5, and the outlet end of control valve two 3 is passed through The pipeline 5 is connected to the suction end of the vacuum pump 1; it also includes a one-way check valve 6, and the intake end of the one-way check valve 6 is connected to the exhaust end of the vacuum pump 1 and the control valve 2 and 3 through the pipeline 5 at the same time. It also includes three air pressure sensors 7 and a controller 8. The inside of the vacuum box 4, the suction end of the vacuum pump 1 and the exhaust end of the vacuum pump 1 are respectively provided with an air pressure sensor 7, an air pressure sensor 7, and a control valve. 2 and the control valve two 3 are respectively connected with the controller 8 through wires. The gas outlet end of the one-way check valve 6 is connected with the muffler 9 through the pipeline 5 .
本实用新型的工作原理如下： The working principle of the utility model is as follows:
在真空泵1正常运转时，控制阀一2打开，控制阀二3闭合。当真空箱4内的真空度达到要求时，位于真空箱4内的气压传感器将气压信号传递至控制器8，控制器8收到信号后闭合控制阀一2，打开控制阀二3。此时真空泵1的吸气端和排气端连通，使吸气端和排气端的气压相近，真空泵1此时的功耗较低。单向止回阀6防止气体进入真空泵1的排气端使真空泵1的排气端压力回升。由于在真空泵1两端循环的气体部分会通过单向止回阀6排出，此时真空泵1两端的气压差变大，位于真空泵1吸气端和排气端的气压传感器7将检测到的气压信号传递至控制器8，控制器8闭合控制阀二3，在真空泵1两端气压平衡后，打开控制阀二3，使真空泵1始终工作在两端气压平衡的环境下，有效降低了真空泵1在空载时的功耗。 When the vacuum pump 1 is in normal operation, the control valve 1 2 is opened, and the control valve 2 3 is closed. When the vacuum degree in the vacuum box 4 reaches the requirement, the air pressure sensor located in the vacuum box 4 transmits the air pressure signal to the controller 8, and the controller 8 closes the control valve one 2 and opens the control valve two 3 after receiving the signal. At this time, the suction end of the vacuum pump 1 is connected to the exhaust end, so that the air pressures of the suction end and the exhaust end are similar, and the power consumption of the vacuum pump 1 is low at this time. The one-way check valve 6 prevents gas from entering the exhaust end of the vacuum pump 1 so that the pressure of the exhaust end of the vacuum pump 1 rises. Since the gas circulating at both ends of the vacuum pump 1 will be discharged through the one-way check valve 6, the pressure difference between the two ends of the vacuum pump 1 will become larger at this time, and the pressure sensor 7 at the suction end and exhaust end of the vacuum pump 1 will detect the air pressure signal Transfer to the controller 8, the controller 8 closes the control valve 2 3, and opens the control valve 2 3 after the air pressure at both ends of the vacuum pump 1 is balanced, so that the vacuum pump 1 always works in an environment where the air pressure at both ends is balanced, effectively reducing the pressure of the vacuum pump 1. Power consumption at no load.
