Vacuum system. It is a complete vacuum system consisting of vacuum pump, PLC program control system, gas storage tank, vacuum pipeline, vacuum valve and offshore filtration assembly. At present, the system is widely used in electronic semiconductor industry, photoelectric backlight module, mechanical processing and other industries.

                      The vacuum system has already included pumping speed control, intake filtration, main operation data display, operation protection and remote control interface.。Simply connect the power and pipe to the site, which can form a complete vacuum system.The control system of the vacuum system is composed of advanced PLC control system adopt programming, and the touch screen is human-machine interface,Realize full automatic control of vacuum system, workpiece walking, magnetic control target, process setting and execution, alarm protection system, etc.

                      After the vacuum system started，Full automatic control can be achieved in full operationAt work, the vacuum in the vacuum system (that is, the average distribution of the vacuum) is constantly fluctuating within its allowable range.The fluctuation range can be adjusted according to the user's request。The vacuum system of screw vacuum pump, roots vacuum pump, rotary vane vacuum pump and water ring vacuum pump can be achieved.            

    The process technology
When the first vacuum pump fails to set the required vacuum after starting, the second vacuum pumps start to achieve the set vacuum value.After reaching the required setting value, the first vacuum pump stops and then the second vacuum pump stops cycle work.Our vacuum system can automatically control the system in the case of unmanned operation, and the vacuum system can be closed automatically during power failure. At the same time the control box can protect the vacuum pump motor overload and short circuit.

                                                 Working principle

Starting system, the main vacuum pump unit starts to work until the vacuum level in the vacuum tank reaches the upper limit set, the vacuum pump stops running automatically, and the vacuum in the central vacuum system is maintained automatically by the vacuum check valve on the pipe. If the vacuum degree of the vacuum tank drops and is lower than the set lower limit, the standby vacuum pump set will start automatically. The vacuum degree of the vacuum system can maintain a stable vacuum source and meet the requirements of production.
