Is there any way to adjust the speed of the blower?

The operator must be familiar with this regulation before starting the machine and operate the blower in strict accordance with this regulation. 1. Check the lubricating oil level of the oil tank, which should be between the upper and lower limits of the oil dipstick. 2. Notify the substation to supply power to the machine.

3. Check the control cabinet on the machine, there should be no alarm display, if there is an alarm, find out the cause and eliminate it. 4. Select the "Manual" state. (Touch the "Manual" key with your finger).

5. Check whether the pressure relief valve is in the open position (the green light is on when the pressure relief valve is opened). Check that the diffuser should be placed at a very small opening (the diffuser is very small and the green light is on). 6. After the above check and confirm that the fan can be started, press the start button and the blower will enter the starting procedure

Pre-lubricate the auxiliary oil pump for one minute (the auxiliary oil pump is running on the green light). The blower can start running (the green light is on when the blower is running). The pressure relief valve closes slowly (the pressure relief valve opens the green light and goes off, two....

Simple! Serial capacitors can be connected (non-polar capacitors, withstand voltage 400V, a few yuan!) ),10 micro--30 micro-method, adjust according to need, can also be made into multi-gear speed regulation, the larger the capacitance, the higher the number of revolutions, note: the capacitor is not consuming electric energy!

I have modified many kitchens, the effect is very good and power saving, now the fan governor on the market can not bring such a high power of 750W! If you don't know something, you can add me voice answer.

Adjusting the speed of the fan requires the installation of a frequency converter in the circuit to control the fan motor.

Wiring method: 1. The inverter R, S and T are connected to the three-phase power supply.

2. The inverter outputs U, V, and W to connect to the fan motor.

3. COM, RST, RUN fan control signal to control start and stop.

4. The speed can also be regulated by the potentiometer of the control panel of the inverter.

A baffle can be added to the air inlet, and the opening of the moving baffle can adjust the air volume and reduce noise.

Buy a fan governor and install it and it will be solved.

The motor with high power can bring Biqin to move larger fan blades, and there is a higher speed, so the air volume will be larger; On the other hand, if the motor power is small, even if the speed is high, the air volume will be lower than that generated by the high-power motor, even if the blades are small. Power p=f·is the force, and v is the speed of the hand. f=p ·s, p is the pressure.

Therefore, the power p=p ·s·v=p q(q is the flow rate, which can also be said to be the hand and air volume, the volume of wind blown out per unit time. So, the more power, the more airflow.

For the "fan" load, there is no problem in adopting the "pressure and speed regulation" method, both theoretically and practically. We have ready-made products and mature experience in this area, as long as the governor parameters are set reasonably, there will be no stalled rotation and burning of the fan at all. For specific applications, you can contact our technical department.

At present, thyristor pressure and speed regulators are mainly used in the field of speed regulation of "fan" and "water pump" loads.

Although it is not as good as the characteristics of frequency conversion speed regulation, the equipment cost is relatively low, the structure is simple, and the failure rate is low.

Beijing Saidheng --- thyristor fan governor.

It's best to use an inverter! Start and stop of 200 motors! And it may run at low speed for 4 to 5 hours, I don't know how big each motor is, but 200 units must add up to a lot of money, how much electricity can be left every year! You should talk to the leader!

If you use frequency conversion, you need to use PLC, collect temperature data, and control the speed is easy to do!

Economical, affordable,

Hello, the very high family is happy to serve you and make the following answers for you: the steps to turn the exhaust fan into a blower are as follows: 1. First of all, remove the tuyere of the exhaust fan, and then install the tuyere of the blower on the exhaust fan; 2. Remove the rotating parts of the exhaust fan, and then install the rotating parts of the upper blower; 3. Remove the motor of the exhaust fan, and then install the motor of the blower; 4. Remove the tuyere of the exhaust fan, and then install the tuyere of the blower with hunger; 5. Remove the power supply of the exhaust fan, and then install the power supply of the blower; 6. Remove the exhaust pipe of the exhaust fan, and then install the exhaust pipe of the blower; 7. After the installation is completed, connect the power supply of the exhaust fan and the blower, and connect the power cords of the exhaust fan and the blower to the power socket; 8. Finally, turn on the power and adjust the air volume of the blower to adapt it to the required air volume.

The above is the specific steps to turn the exhaust fan into a blower, when changing the exhaust fan, it should be noted that the shell of the exhaust fan should be removed first, and then the blower should be installed step by step according to the above steps, and after the installation is completed, check whether the power connection between the exhaust fan and the blower is firm to ensure safe use.

The blower speed control is composed of a blower speed control switch circuit and a water temperature control switch circuit. Blower speed control switches include: automatic air conditioning amplifier, blower resistor, and power transistor.

The power transistor changes the blower speed by changing the current flowing to the blower motor based on the blower drive signal from the BLW terminal of the air conditioner amplifier. The power transistor has a temperature control fuse with a melting point of 114 to protect the transistor from damage due to overheating. The water temperature control switch circuit is a water temperature sensor that senses the engine coolant temperature and controls the engine preheating.

The blower speed control operation process is as follows:

1 Automatic control of blower speed.

The automatic control process of blower speed is similar to temperature control, which is to automatically control the blower speed according to the TAO value. The auto switch is located on the control panel of the heater. When this switch is switched on, the automatic air conditioner amplifier controls the blower speed according to the current intensity of the TAO.

1) Low-speed operation.

The auto switch is located on the control panel of the heater. When this switch is turned on, the microcomputer installed in the amplifier of the automatic air conditioner turns on TR1 and starts the heater relay. This causes the current to flow from the battery to the heater relay, then to the blower motor, then to the blower resistor, and then to ground.

In this way, the blower motor runs at a low speed. At the same time, the Auto (Auto) and Lo (Low Speed) indicators are on.

2) Medium-speed operation.

When the auto switch is switched on, the heater relay is activated, as in the case of low-speed control. A microcomputer (ECU) installed in an automatic air conditioner amplifier outputs the blower drive signal calculated from the TAO value to the power transistor via the BLW terminal. The current then flows from the battery to the heater relay, then to the blower motor, then to the power transistor and blower resistor before grounding.

In this way, the blower motor is run at a speed corresponding to the blower drive signal. At the same time, the Auto (Auto) indicator lights up, and the LO (Low), M1 (Medium 1), M2 (Medium 2), and Hi (High) indicators may also light up depending on the situation.

The signal from the power transistor to the VM terminal of the automatic air conditioner amplifier is a signal that reflects the actual speed of the blower. A microcomputer (ECU) uses this signal to correct the blower drive signal.

3) Extra-high speed operation.

When the Auto switch is switched on, a microcomputer (ECU) installed in the amplifier of the automatic air conditioner is allowed to turn on TRL and TR2 to drive the heater relay and blower relay. The current then flows from the battery to the heater relay, then to the blower motor, and then to the blower fan relay to ground. In this way, the blower motor is run at a very high speed.

At the same time, the Auto and HI indicators are on.
