Points for Attention in the Use of Microwave Drying Equipment

1. The operators of microwave drying equipment must have professional training, and the operators must have certain basic knowledge of electrotechnics.

2. Before the microwave drying equipment is running, it is necessary to check whether the microwave cavity has foreign body or metal material, and clean it up immediately if necessary. On the other hand, the components of microwave drying equipment should be inspected before start-up to avoid electric shock and leakage accidents.

p>3. In the production process of microwave drying equipment, it is necessary to check whether the equipment is broken at any time. Because long time no-load equipment will cause great damage to the equipment. On the other hand, we must pay attention to avoid the relevant personnel directly open the furnace door to check, in order to avoid microwave leakage.

Microwave drying equipment operation process:

1.Preparations

1) Check whether the power supply of the equipment is normal and the equipment must be grounded well;

2) Observe whether the door is closed;

3) Place all the control switches on the control panel in the state of “ close”

4) Prepare materials or false loads;

4) Close the air switch of the total power supply;

5) Turn on the control surface of the speed regulating motor. The panel display adjustment is set at zero state;

2. General control method: turn on

1) After switching on the emergency stop switch, the control system circuit is energized and the door indicator lights are on; turn on the monitoring switch, the thermometer shows room temperature; and the heating box lights are on.

2) Standby light of microwave switch is on.

Basic control: The general starting sequence is: heat-discharge & mdash; & rarr; & humidity-discharge & mdash; & rarr; & Fan & mdash; & rarr; & Drive & mdash; & rarr; & microwave N, starting to add materials after turning on transmission (before turning on microwave), microwave switch standby lights on and off, other switch lights on and off. Microwave N microwave N is composed of 21 knob switches, i.e. microwave 1-microwave 21 is manually adjusted. Customers can change the microwave output power at any time according to the actual production process. The anode ammeter on the working state control panel shows the working condition of the magnetron. The working condition of the magnetron in a heating box is controlled by two control knobs and monitored by a single meter. The current of a magnetron working normally is about 0.28-0.3A. The main function of

temperature display is to provide reference data for customers when making materials and processes. After the drive is set to start the drive, the switch of the governor will show 0. There are keys or knobs on the governor to adjust or adjust the size. With the increase of the number, the speed of the motor will be accelerated and vice versa, it will be slowed down. Attention: In order to avoid operator's negligence and safety, the door, transmission, heat exhaust, humidity exhaust and fan of the control system interlock microwave, that is, before opening the microwave switch, the door must be closed, transmission, heat exhaust, humidity exhaust and fan must be switched on effectively; some customers sometimes need microwave to open when the transmission stops, only the main circuit of the transmission is needed. The purpose can be achieved by switching off the circuit breaker.

2, shutdown

1) The general start-up sequence is: microwave N stop & rarr; turn off & drain humidity & rarr; turn off & drain heat & rarr; turn off drive & rarr; turn off heat sink fan & rarr after 10 to 15 minutes; shut down urgently;

2) turn off the total power supply.

3. When temporary shutdown is needed in abnormal circumstances, please do the following operations:

1), press the emergency shutdown switch

2, turn off the microwave switch and stop the microwave output (under normal circumstances).
