Description

Evaporative cooling ventilator driven by speed regulating motor

Technical field:

The utility model relates to the technical field of evaporative cooling ventilators, in particular to an evaporative cooling ventilator driven by a speed regulating motor.

Background technique:

At present, the evaporative cooling ventilator gradually replaces the traditional mechanical refrigeration and air-conditioning equipment with its advantages of environmental protection and energy saving and cooling in large open spaces. The cooling principle is: when the water evaporates, it takes away the surrounding heat, thereby reducing the temperature of the air . Its working principle is: through the fan to draw air, negative pressure is generated inside the machine, the air passes through the cooling curtain, and at the same time, the water pump continuously pumps out the water from the chassis and enters the water distribution pipe on the cooling curtain, through the water distribution pipe and the hydrophobic curtain on the top of the cooling curtain, the water Evenly wet the contact area of the entire wet curtain, and the evaporation of water can absorb a large amount of heat in the air, so that the cool, moist and fresh air is sent out through the ventilator. Among them, the fan of the ventilator plays the role of exhausting and supplying air. At present, the fans of the ventilator are mostly driven by ordinary motors. This ordinary motor has fixed power and speed, so the ventilator does not have the ability to adjust the wind speed. function, will cause waste of resources, and cannot meet the needs of different places. The speed control currently used is frequency conversion speed control, which has high cost and complicated control installation, and cannot meet the needs of general users.

Utility model content:

The purpose of this utility model is to provide an evaporative cooling ventilator driven by a speed-regulating motor in view of the deficiencies of the existing technology, and to apply this technology to the evaporative cooling On the ventilator, the principle is to use the trigger pulse to control the conduction angle of the thyristor, and use a special process on the motor so that the motor will not cause excessive temperature rise when the motor is running at low speed. The speed gear is used to adjust the wind speed, the operation is simple, and the resources are used rationally.

In order to achieve the above object, the technical solution adopted by the utility model is: it includes a chassis, the chassis is composed of two side plates and an upper cover plate, the front and rear of the chassis are respectively provided with air nozzles and water curtains, and the air nozzles and water curtains are arranged between There is a fan, and a water collection tank is arranged at the bottom of the case, and a water pump is provided at the bottom of the water collection tank. The fan includes a wind impeller and a motor connected to the wind impeller, and the motor is a speed-regulating motor. Chopper adjustment device.

After using the speed-regulating motor, set the speed-regulating button on the control panel. By setting the speed-regulating gear, the speed of the speed-regulating motor can be controlled, and then the wind speed of the ventilator can be controlled to realize the adjustment of the air supply volume and cooling of the ventilator. control, so the utility model has the following advantages:

(1) Stepless speed regulation can be realized, the adjustment range is wide, it is convenient for users to use, and 9 gears of speed regulation can be locked on the software;

(2) The starting current is small, avoiding the impact on the factory power grid, and it is safer to use;

(3) The noise decreases with the decrease of air volume;

(4) According to the change of air temperature, the air volume can be adjusted at will, and the energy consumption will decrease with the decrease of the air volume, and the energy saving effect will be more significant;

(5) The acceleration and deceleration smooth transition control technology is adopted, which has little impact on the motor and fan blades, and the machine has a longer service life;

(6) Compared with frequency conversion speed regulation, it has the characteristics of simple structure, low cost, low failure rate and easy control.
