What do I need to pay attention to in Roots fan maintenance?
Roots FansThe use of the process can not be separated from the maintenance, then the Roots fan maintenance process in those matters of attention? Roots fan editor to take you to understand.
First, air cleaning, regular cleaning: pay attention to the surrounding environmental health, no debris or no oil around the fan, keep good ventilation. In terms of air cleaning, regular cleaning of the fan inlet sponge filter, and with the internal cleaning of the fan in overhaul, has been able to meet the fan's cleaning requirements and production requirements.
Second, fan lubrication, lubricating oil to keep in the oil window in the red position, such as adding too full will overflow with the fan running heat, too little will damage the fan. Ensure the effectiveness of lubrication facilities and lubricating oil is very necessary.
Third, mechanical operation will temperature rise, Roots fan, especially in the summer to pay attention to, fan in the hot season when running at full load, easy to appear the whole machine over-temperature (export temperature exceeds 85 ℃), the failure rate increased in vain and the wind fell. It is necessary to keep the fan room well ventilated. Self-designed production of a simple water cooling device, from top to bottom flow through the fan casing surface to take away part of the heat, to achieve the purpose of cooling, to help the fan safely through the high temperature season. This cooling device is simple and easy to implement, only in the annual high-temperature season (temperatures over 30 ℃) during the opening, the time is about 3 months. If conditions allow, you can also install air conditioning to cool down.
Fourth, pay attention to observe the export temperature, pressure and ammeter display whether the standard is exceeded, whether the oil level is normal, whether the oil leakage leakage, vibration or noise is abnormal, touch the bearing housing and other parts of the temperature is normal, such as the belt slack tighten in time, such as the belt is broken, to be replaced in a timely manner.
