Fans have a good condition

Look after the operation and speed performance is energized to rotate toggle switch back and forth a few times, check whether the failure or tight fitting, in this process, the fan mechanical transmission parts should not have abnormal noise. industrial electric fans in high, medium and low speed, the motor and blades should be smooth, low vibration, low noise. oscillating stand fan shook his head, shut down should be agile, non-stop, arrest and jitter, the speed difference of each block should be obvious, air angle bigger the better. When the fan stops, the shaft axial clearance is not more than 0.5 cm, the gap is too big, it will cause axial movement and there is a crash during the operation.

After watching for leaks fan powered hand touch if there is a strong hemp inductance, with test pencil test, test pencil will light emitting display, can determine the shell leakage, can not choose.

How to choose a fan

See activity part of the performance fans fan head stoop, Yang each angle flexible operation, locking securely, adjusted to the maximum depression or shake his head to the final position, grille shall collide with electric fan heaters pillars. When the fan is running, stability is better, not dumping, shaking his head angle of not less than 60-80 degrees.

Look at the merits of start-up performance starting performance is an important indicator of quality fans. Inspection, should be adjusted in a slow gear, and start fan at 85% of rated voltage power supply, which uses 220 volts regulator will be reduced to 187 volts, electricity phoenix fan should start from a standstill, and the normal operation, a fan from the start to the normal operation of shorter the time required to start the electric stand fan motor, the better the performance

How to buy a fan

Each industrial electric fans watching random file random file includes instructions, product certification, electrical wiring diagrams and packing slips, purchase inventory in accordance with the packing list, check the quantity and quality components.
Look grille and fan there is an obvious distortion in the assembled fans cast nets, a fan with a pen pointing to the highest point, slowly moving blades, a few other points that corresponds to the distance from the blade tip shall be very close, and then turn the blades, to observe the rotation is light and flexible, and can be stopped at any position.
Look control mechanism is flexible control mechanism includes speed control switch, timer knobs, toggle switch, light switch, etc. These control mechanism should be flexible operation, heater with fans reliable contact. To speed block, two block at the same time are not allowed to turn on or does not go a block by the phenomenon. Press the stop button, each speed gear should be normal reset button

so people will feel cool

When the floor standing fans work (assuming no heat transfer with the outside room) not only did not reduce the indoor temperature, it will rise. To analyze the cause of temperature rise: When fans work, due to the current through the fan coil wire is resistance, it will inevitably produce an exothermic heat outside, the temperature will rise naturally. But why people will feel cool it? Because the body's surface have a lot of sweat, When fans work together, indoor air can flow together, so we can promote the rapid evaporation of sweat, combined with evaporative need to absorb a lot of heat, heater with fans so people will feel cool.

Fans of the main components

The main component is a electric stand fan of: AC motor. Its working principle is: energized coil in a magnetic field by the force of the rotation. Electrical energy into mechanical energy, and because the coil resistance, and therefore there is an inevitable part of the electrical energy to be converted into heat. In addition, DC motors, brushless DC motors and other small power small floor standing fan motor applications are increasingly being used in

according to user requirements

stainless steel housing, compact structure, attractive appearance; anti-corrosion, anti-shock, resistant to moisture;low operating costs, the choice of the company's intelligent control system, electrical heater using a computer instead of the human brain, behavioral energy saving, to achieve the desired energy savings in the context of the same heating effect.directly to the electrical energy into heat energy, gas room heaters not only saving valuable non-renewable resources, while fundamentally solve the plumbing system to run, run, drip, leak and other issues.also cover the surface electrostatic spraying various colors desired by the user;power ranges from 600W ~ 2000W, dimensions can be customized according to user requirements
