Different operating tank air box normal shutdown and emergency shutdown 2, cabinet wind chassis Normal stop: the unit normal shutdown operations held by the following steps. · Gradually open vent valve (or outlet bypass valve), together gradually close the exhaust valve. · Gradually shut the door to a small intake saving 20 ~ 25 °. · Press the parking button, and presence or absence of dependable shutdown process very appearance. ? When continuous supply unit after consecutive 5 ~ 10min, probably bearing temperature drops below 45 ℃. To deal with a floating ring seal unit, there is need to continuously seal pump oil until the body temperature is below 80 ℃ in a row. Centrifugal wind chassis choice points and Failure Analysis centrifugal wind chassis is initiated by the motor rotating impeller, the impeller blades to force gas rotation, acting on the gas, wind chassis manufacturers to increase energy, gas under the influence of centrifugal force, the impeller thrown around, resolved to speed scroll type casing can be converted into pressure energy, when the gas impeller exclusion, wind chassis customization, pressure impeller is lower than the inlet pipe pressure, the new gas at a pressure difference inhalation impeller, gas is continuously kept marginalized from the pump, air box, a centrifugal fan product choice points 1. wind chassis air flow control parameter selection, total pressure, efficiency, noise, and electrical power. Centrifugal and axial flow. 2. Fan the provision of the wind chassis, muffler favor. 3. When the fan selection should consider the loss of air leakage pipeline system, strategy errors, and negative real problems ventilator wind, air pressure, and as usual acceptance of wind capacity of 1.05 to 1.1, pressure is peaceful coefficient of 1.10 to 1.15 . But I do not accept too large to guard fan long run in a low efficiency area. 4. meticulous pipe network resistance characteristic feature of standing room and fan relationship. In order to secure the fan can run, fire ventilation wind chassis, should make the fans something similar at its highest efficiency point, what point fan performance curve to the right of the peak point of the total pressure (ie, the amount of wind side, and as usual located Total pressure peak 80%). Wind chassis _ _ low-noise wind chassis Sheng clean air conditioning (certified merchants) are provided by the Texas Air Conditioning Equipment Co., Ltd. Sheng-purification.
