Operation and maintenance of a compression hot air dryer?
The compressed heat dryer uses internationally popular industrial colors to meet various human needs. It is energy-efficient during use, saving more than 25% energy compared to similar products under standard operating conditions. It also uses physical principles to freeze the moisture in the compressed air below the dew point. Below is an introduction to the operation and maintenance of the compressed heat dryer?

It also uses physical principles to freeze the moisture in the compressed air to below the dew point. Let's introduce the operation and maintenance of the compressed heat dryer?
There is also a lot of basic information that needs to be understood when using a compressed heat dryer. First, we need to understand its main function. In fact, this equipment uses refrigerant and compressed air for heat exchange, reducing the temperature of the upstream compressed air to 2~10 ℃ range dew point temperature, during use, it can effectively remove water vapor, oil mist and particulate matter from the air. And its operation mode is manual and automatic operation. According to the needs, determine continuous operation or intermittent operation. Before use, the compressed heat dryer must be checked. For example, all valves in its pipe network system are in normal standby state. Of course, its cooling water valve is open, and the water pressure should be 0.15~0.4MPa between (refer to the supplier's technical manual), and the water temperature is 31 ℃ or below. In addition, when using it, we also need to understand that the refrigerant high-pressure gauge and refrigerant low-pressure gauge on the instrument panel of the compressed heat dryer have indications and are basically equal. Check whether the power voltage, phase, and frequency meet the regulations, and the voltage must not exceed the rated value 10%。
The startup and operation of the compressed heat dryer are also issues that need attention. When starting, you can press the button first, and the AC contactor will delay 3 minutes before starting, and the refrigerant compressor will start to operate. Then it is recommended to observe the instrument panel, the refrigerant high-pressure gauge should slowly rise to 1.4MPa approximately, and the refrigerant low-pressure gauge should slowly decrease to 0.4MPa approximately; at this time, the machine has entered normal operation. In addition, when the compressed heat dryer is running 3~5 minutes later, you can slowly open the inlet air valve, then open the outlet air valve according to the load increase rate until full load. The operator can also check whether the inlet and outlet air pressure gauges are normal. At the same time, it is also necessary to check whether the automatic drainer drainage is normal. It is also recommended to regularly check the dryer operating conditions and record the inlet and outlet air pressure, refrigerant high and low pressure, etc. After the compressed heat dryer is manually put into operation normally, it can be switched to "remote" and "automatic" operation according to the electrical instrument design system, and controlled by the central control system during operation.
