High pressure fan failure

IPC summary: avoid high pressure fan mainly pay attention to the following several points of failure
A) first two aspects protection high pressure fan needs:
1. pressure: pressure will cause the wind shell high temperature fan no traffic for a long time, causing aging fan bearing. For the pressure, often using a pressure-release valve, it is a unloader valve, when the use of high pressure air pressure exceeds the pressure-release valve set pressure, pressure release valve will automatically open and release excess pressure, which protection the high-pressured air blower.
2. dust: high pressure fan working environment too much dust will stick to the fan impeller and bearing high pressure fan causing blockage causing fan not spinning. For dust, often using a filter. It is used depending on the scene, often use different filter filter precision, different filters have different maintenance and longevity, you needed to ask when ordering.
B) followed by high pressure fan failure is caused by selection of bearings
1. bearing lubrication of bad quality. The purpose of lubrication, friction is generated so that part is not in direct contact and friction between solid and liquid. If the quantity of lubricant inadequate or poor quality, will make some direct frictional heating, or heat cannot pass oil away, temperature and high pressure air bearings.
2. bearing Assembly of bad quality. Inner sleeve and shaft tight enough, coat and bearing clearance is too large or too small.
3. felt too tight and heat sealing, compressing the air.
4. high pressure fan bearing vibration is too large to sustain the impact load, seriously affect the stability of oil film.
5. high pressure fan bearing insufficient cooling water or interrupt, affecting heat brings out, displacing the bearing temperature rises.
6. high pressure air bearings are of bad quality. Bearing scraper grind of bad quality, oddiyana, poor contact or how-to; rolling bearing rolling decent were cracked, chipped, flaking, and would undermine the uniformity and stability of oil film, surface heating in the bearings.
C) high pressure fan failure is caused by ambient temperature
1. in some environment temperature high of occasions, high pressure wind machine needs for special of protection: like in sealed environment in the using Shi, to note ventilation thermal; Dang environment temperature (intake temperature comparison high Shi), more to note ventilation thermal, or select allows into wind temperature high of high pressure wind machine (like has a paragraph wind Parker high pressure wind machine, allows into wind temperature can up 80 degrees);
2. high pressure fan in some ambient temperature too high for special occasions, long-term high temperature high pressure fan bearings for high temperature bearing lubricant rapid volatilization, causes bearing jammed, resulting in high pressure fan does not turn.
Overheating I produced the wind park high pressure fan from Sweden and Japan original imported high temperature resistance of SKF and NSK bearings (heat resistant up to 150 degrees), allowing high pressure fan can operate in the ambient temperature is too high. Motor standard in full accordance with Taiwan TECO standard and high quality.
