Product Name: Precision Oven Model: QC-600B

1. Scope of application: used in plastic, hardware, spraying, single-sided, double-sided, multi-layer circuit boards,

Drying and preheating of soft boards and electronic components. 

2. Exterior structure and main parameters and unit price

Three, the main performance

1. The outer shape of the furnace adopts high temperature electrostatic spray, which has corrosion resistance, wear resistance, rust resistance,

It is not easy to age and easy to clean.

2. The inner tank is made of 1.2mm thick 201 stainless steel plate, which does not rust and makes the furnace clean and free

Dust and so on. The bottom is equipped with movable casters for easy handling of the oven.

3. Good heat insulation system: high-temperature silicic acid heat insulation rock wool is spread around the inner tank and increased around the door 

High temperature resistant sealing silica gel to achieve a good sealing effect, avoid unnecessary heat loss, and make

The temperature outside the furnace is not hot, and the heat preservation effect in the furnace is good. And the insulation layer adopts enough space and insulation

Thermal system, so that the heat does not leak out, which can speed up the warm-up time, improve work efficiency, and

It can also save power at the same time.

4. Control system: power supply 380V, equipped with a control electric box on the right side of the oven, the temperature is room temperature to 250

The temperature can be adjusted arbitrarily, the functions include PID self-tuning, automatic constant temperature, automatic timing, time-to-temperature alarm and power failure, over temperature power failure, leakage protection circuit breaker, motor overload protection and other functions, dual temperature controller control (with over The temperature upper limit thermostat prevents the main thermostat from losing control and damaging its products), using SCR electrical output to make the temperature more accurate, and the internal temperature difference is plus or minus 2 degrees. When the temperature reaches the set temperature value, the oven is at a constant temperature at this time, and the thyristor uses the temperature to control the current, thereby reducing the power of the entire oven to achieve power saving effect. Subverting the traditional zero-crossing triggering caused by the impact of large instantaneous power supply and large temperature fluctuations, etc.

The FD-301 output temperature controller can make the output voltage change steadily and linearly, the temperature control effect is more stable, and the performance is better. (The output power can be automatically adjusted according to the temperature error) to make the temperature more accurate.

5. Heating system: adopts the latest cutting-edge technology and high-tech materials, and has obtained national patents. It has the principle of heat reflection and heat conduction, which saves more than 15% of energy and has a longer service life than ordinary heating tubes. According to the internal volume of the furnace, two fan devices are equipped on the top of the furnace cavity to form a certain air pressure in the furnace to ensure that the temperature pressure reaches the entire furnace space, achieving the purpose of small temperature difference and uniform temperature, thereby ensuring the quality of the baked goods.

6. Air intake and exhaust design: equipped with air intake and exhaust valves, the air flow can be adjusted to make the temperature in the furnace more uniform. Using advanced air pressure preheating principles, the cold air is preheated and delivered to the furnace through the wind pressure boosting system, and the exhaust gas and organic matter in the furnace can be discharged in time, so as to achieve a clean, fresh and good environment in the furnace to ensure baking Quality and increase the baking speed, the technology

It can save more than 10% of power consumption.

7. Air duct design: built-in wind trough, adopting three-sided circulation (left, right, bottom) high wind

Forced horizontal (or left and right) wind mode, with wind pressure splitter plates on both sides, and wind passes through

The uniform holes of the stainless steel manifold in the furnace penetrate the entire furnace space, so that the temperature in the furnace is uniform.

Evenly distributed.

8. Powerful dual-circulation air conveying system: the heated hot air is under the action of the air conveying fan on the top of the stove.

Pass the hot air through the air ducts on both sides of the furnace and blow it into the furnace evenly from top to bottom to make the furnace

The temperature is kept uniform, and the heat is not easy to lose, so as to achieve the effect of energy saving and power saving.

Save more than 25% of electricity.

Four: structure

Instructions

One. Boot and performance operation

1. The main switch and phase sequence protection switch are installed in the electric box. After the power cord is connected, make sure that the phase sequence switch works normally when the main power switch is normally open. If the indicator light is on, it means it can work normally.

2. The control panel is equipped with power switch, heating switch, fan switch, timing switch, main temperature control, overtemperature meter, chronograph, ammeter and voltmeter.

3. The power switch is to control the operation of the entire control system.

4. The heating switch is the heating power supply that controls the heating tube. The heating tube can only work when the heating switch is on, and the heating switch can be normally opened without being closed when other growth conditions are not required.

5. The fan switch is to control the power supply of the wind motor. The fan can only work when it is on. When no other growth is required, the fan switch can be normally opened and does not need to be closed.

6. The timing switch is to control manual timing or automatic timing. When the timer switch is turned off, the timer does not start until the set temperature is reached. If it is not necessary to reach the set temperature timer, turn on the timer switch.

7. The main temperature control is to control the required temperature operation. (The specific operation is based on the operating instructions of the temperature control meter)

8. The over-temperature meter plays a role of on-line protection. When the temperature exceeds or equals to the set temperature, it will alarm and stop

Stop heating function. Therefore, the temperature set by the overtemperature meter is 10 degrees higher than the temperature set by the main temperature control.

Right, left and right will not affect normal work.

9. The timer is to set the time required for the baking process. Once the set time is reached, it will be generated

Alarm reminder function.

10. The ammeter is to observe the current generated by the equipment when it is working, and it can also be based on the size of the current

Know if the equipment is working properly.

11. The voltmeter is convenient to observe the power supply voltage.

two. Precautions for equipment use

1. Before each use, check whether the equipment is operating normally, whether the wind fan is operating normally, and whether there is

Bad reaction. If the operation is not normal, it is necessary to notify the professional repair personnel to repair and maintain.

2. Pay attention to whether there are flammable and explosive materials around the equipment when it is working.

3. Flammable and explosive items cannot be baked in the oven

4. The equipment should be checked and cleaned regularly. Maintenance requires professionals.
