To realize the one-key start-stop of air compressor and cold dryer, the automatic start-stop control method and chain start-stop technology can be used in combination. The following are the specific implementation steps:
automatic start and stop of 1. air compressor
time-based control:
install a timer with accurate timing function and connect it to the control cable of the air compressor.
Set the start time and stop time of the timer, so that the air compressor starts and stops automatically according to the set time every day.
Pressure based control:
install the pressure sensor at the air inlet of the compressor and connect it to the controller.
Set the starting pressure and stop pressure values of the controller to realize the automatic shutdown of the air compressor when the air pressure is reduced to the stop pressure, and the automatic start when the air compressor is increased to the start pressure.
Automatic start and stop of 2. cold dryer
confirm whether the cold dryer has automatic start-stop function. If not, additional controller shall be installed.
According to the instructions of the control box of the cold dryer, open the control box and set the automatic start-stop function.
Set the conditions for automatic start and stop, such as temperature, humidity or load and other parameters, when these conditions are met, the cold dryer will automatically start running, and automatically stop after reaching the set target.
3. to achieve a key chain start-stop
select hard chain or soft chain mode to realize the chain start and stop of air compressor and cold dryer.
Hard interlocking requires the installation of dedicated electrical hard interlocking devices, involving additional installation and wiring work.
The soft chain is realized by the controller, which is low in cost and convenient to realize, and only needs to set the corresponding chain start-stop parameters in the controller.
4. integration system
integrate the control systems of the air compressor and the cold dryer to ensure that they can communicate with each other and receive unified control instructions.
A master control switch or button is set in the integrated system to realize one-key start-stop function.
By pressing the master control switch or button, at the same time send start or stop instructions to the air compressor and cold dryer, so as to achieve a key chain start and stop.
5. considerations
when setting automatic start-stop and interlocking start-stop, make sure that the electrical connections of all equipment are correct and follow the relevant safety regulations.
Regular maintenance and inspection of equipment to ensure the normal operation of sensors, controllers and interlocking devices.
Pay close attention to the operating status and alarm information of the equipment during use, and deal with possible failures or abnormal situations in a timely manner.
The optimum working pressure of the blow molding machine needs to be set according to the preform material, bottle design and process requirements, usually between 2.5 and 4.0 MPa (25 to 40 bar). The following are specific instructions and optimization suggestions: 1. core pressure range Standard range of conventional PET bottles: blown

Air compressor: the core power source in general industrial equipment-analysis of granklin air compressor industry adaptability air compressor (air compressor) as the basic equipment in the industrial field, because of its widely used in manufacturing, energy, medical, food and other
The pressure setting of the air compressor needs to be determined according to the specific application scenario to achieve the best effect. Generally speaking, the pressure range of the air compressor at work is relatively wide, ranging from low pressure to high pressure. In common use scenarios, the working pressure of the air compressor is usually set.
