First, the use and characteristics of high efficiency and low noise mixed flow high temperature exhaust fan
PYHL-14A high efficiency and low noise mixed flow high temperature smoke exhausting fan can be used for smoke prevention and exhaust system in high-rise buildings and underground buildings. Has the advantages of high efficiency, low noise, wide use, normal ventilation and fire gas fire smoke, a dual-purpose machine features.
.
Two. Maintenance and storage of high efficiency and low noise mixed flow high temperature smoke exhausting fan
1 the environment should be kept clean and tidy, the surface of the fan is kept clean, the inlet and outlet of the air vent should not have sundries, and the dust and other sundries in the fan and the pipe are removed regularly.
2, it can only work under the normal condition of the fan. At the same time, we must ensure that the power supply facilities are adequate, the voltage is stable, and the operation is strictly prohibited. The power supply lines must be private lines, and the temporary lines should not be used for long time.
3 during the running of the fan, it is found that the fan has abnormal sound, the motor is seriously heated, the shell is electrified, the switch is tripped, and it can not start. In order to ensure safety, it is not allowed to be maintained during the operation of the fan, and the test operation should be carried out for about five minutes after overhaul to confirm that there is no abnormal phenomenon and reopen the machine.
4 according to the environmental conditions using irregularly to supplement or replace the bearing grease (motor bearing grease closed without changing the service life of the period), in order to ensure good lubrication fan in the operation process of the gas of not less than 1000 hours / times enclosed bearings and motor bearings, gas filling bearing with zl-3 lithium base grease 1/3, is running short of oil.
The 5 fan should be stored in a dry environment to prevent the motor from dampened. When the fan is stored in the open air, there should be defensive measures. In the storage and transportation process should prevent fan bump, so as not to damage the fan
Three, application of high efficiency and low noise mixed flow high temperature exhaust fan
High efficiency and low noise Francis high-temperature exhaust fan can be used for metallurgy, chemical industry, light industry, food, medicine and civil construction places such as ventilation or enhance heat dissipation. If the shell is removed, and can also be used free fan, but also in the exhaust pipe to the longer interval are arranged in series, in order to improve the air pressure in the pipeline.
.
Four. Characteristics of high efficiency and low noise mixed flow high temperature exhaust fan
The high efficiency and low noise mixed flow high temperature exhaust fan series fan has the characteristics of simple structure, stable and reliable, small noise and wide range of function.
