What's the difference between the fan of gas water heater installed in the upper part and installed in the lower part?

The above are forced suction forced exhaust, all of which use the second high voltage AC motor. Here is the powerful exhaust of the powerful drum. They generally use 24V brushless motor, which can adjust the speed synchronously and stepless according to the size of fire, so as to achieve the intensity of gas combustion. High thermal efficiency, the motor is not easy to break down at low temperature.

Variance 1:

The above are forced suction forced exhaust, all of which use the second high voltage AC motor.

Advantages: strong smoke exhaust ability, and automatic judgment of fault shutdown when the smoke pipe is blocked.

Disadvantages: only two speeds, low efficiency, high temperature near the motor, poor heat dissipation, easy to burn out the motor.

Difference 2:

Here is the powerful exhaust of the powerful drum. They generally use 24V brushless motor, which can adjust the speed synchronously and stepless according to the size of fire, so as to achieve the intensity of gas combustion. High thermal efficiency, the motor is not easy to break down at low temperature.

Disadvantages: the exhaust capacity is a little poor, and sometimes it is impossible to judge whether the smoke pipe is blocked. The fan is mainly composed of the following six parts: motor, air filter, fan body, air chamber, base (and oil tank) and oil dripping nozzle. The blower operates eccentrically by the rotor in the cylinder, and the volume between blades in the rotor slot changes to suck, compress and discharge air.

During operation, the lubricating oil is automatically sent to the oil drop nozzle by using the pressure difference of the blower and dripped into the cylinder to reduce friction and noise and prevent the gas in the cylinder from flowing backwards. This type of blower is also called vane blower.

Advantages: To be sure, the lower set of DC fans is definitely better than the upper set of AC fans. Now the exhaust capacity of the blower of the lower unit has been greatly improved, which is also the highest standard of exhaust capacity in the industry. 5 meters high, 3 bends, and the AC fan set on it can't be realized. The larger displacement can reach 7 m 4 curve type.

Extended data:

The difference between gas water heater and electric water heater;

Of course, if you can choose, you should choose electric water heater, because it is more environmentally friendly, and the design mode of gas water heater is backward. For the exhaust gas water heater, it needs indoor oxygen, and the exhaust gas is indoors. Nowadays, products are generally new but powerful dispatching water heaters.

Electric water heaters are safer, more environmentally friendly and more economical in power consumption. Because the electric water heater can preheat, it saves a lot of energy compared with ordinary heating. If you can choose an electric water heater, of course, it is because it is more environmentally friendly, and the design mode of gas water heaters has fallen behind.

For exhaust gas water heaters, indoor oxygen and waste gas are needed. Nowadays, the new but powerful dispatching water heater, electric water heater, is safer, more environmentally friendly and consumes more electricity. The preheating mode of electric water heater is more cost-effective and saves a lot of energy than general heating.
