I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation equipment. Exhaust fan troubleshooting 1, because the oil in exhaust fan failure caused by water's sake. Oil with too much water, fumes contain water vapor, when water vapor condenses encounters cooler to water pipe, condensate in the exhaust fan outlet duct fume separator poor drainage situation back to fans via its outlet pipe shell, and then enter the motor from the fan casing, causing the coil insulation decreases causing motor burned out. 2, because the transformation of fan selection is too large. In order to reduce negative bearing box, turn down the fan outlet throttle 20% open, ensure that the main fuel tank negative pressure of -150 ~ -250Pa. Thus, the exhaust fan pressure -, plus export the throttle opening is too small, resulting in water, oil difficult to drain away from the case, long-term retention in the fan casing, resulting in motor burned out after entering the motor. 3, because the motor seal problems because of trouble caused by the exhaust fan. Motor seal problems, leading to moisture into the motor causes the motor to burn out from the fan housing. Cause when the fan outlet throttle opening is adjusted to 20% of the fan casing pressure - to promote water easier access to the motor, the motor burned exacerbated frequency Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling curtain, chiller suppliers.

I believe Jinxiang Yun plant cooling ventilation plant must be your best choice for cooling ventilation equipment centrifugal fan output may drop the following reasons: 1: motor failure such as a short circuit in stator winding partial speed dropped .2: impeller may have polluted It was paid with the load increase the impact of its speed .3: impeller unbalance (at the same time there will be abnormal vibration) 4: Are there obstacles inlet substances into the air inlet valve off as small or dirty air inlet filter clogged and other reasons. Nanchang Jin Xiangyun plant cooling ventilation equipment is a professional sales suction fan, cooling water curtain, chiller suppliers.

I believe Jinxiang Yun plant cooling ventilation plant cooling equipment must be your best choice for ventilation exhaust fan fire suction device which specific classification 1, bee wheeled suction device: the exhaust fan fire wheeled suction device is a bee new types of harmful gas purifying device, suitable for low concentration, the amount of wind conditions, with relatively light quality, volume is relatively small, the operation is very simple and other advantages. 2, fluid bed adsorber: fluidized bed adsorber adsorbent multilayer fluid bed adsorber wet curtain fan, purified by means of a gas flow rate greater wet curtain fan pictures, it was fluid suspension state status. The main advantage of fluidized bed adsorber is contacted with an adsorbent gas is better suited for continuous control of gas emissions and greater pollution. 3, fixed bed adsorption apparatus: fixed bed adsorption device is mounted on the exhaust fan fire mostly fixed adsorption layer adsorption layer penetrate to replace the adsorbent. If the concentration of harmful gases is relatively low, but volatility is not, do not consider adsorbent regeneration wet curtain fan cooling, to ensure the safety case to dispose of the adsorbent and adsorbate. Fire exhaust fan suction device specific classification is mainly these, I believe we have some understanding, and we must be reasonable use of it, the only way to get full use of its performance.
