Tiger power-- Oil fume exhaust device of steam turbine

brief introduction

1、 Defects of traditional fans
The oil fume exhaust fan is a traditional horizontal structure, the seal between impeller and volute is not tight, the bottom of volute is easy to accumulate oil, and the oil leakage between impeller shaft and volute is serious. The fan is an ordinary centrifugal fan. Either the output is insufficient or the negative pressure is too large, which results in water in the oil, the turbine oil emulsification, the oil pipeline system rusts, and the regulating element fails, which seriously threatens the safe operation of the unit. As the negative pressure is too large, a large amount of turbine oil is extracted, and the oil outlet appears oil injection phenomenon, which greatly wastes the civilized production of the power plant. At the same time, due to the excessive negative pressure, a large number of shaft seal leakage steam enters the bearing box, and then goes into the main oil tank along with the return oil main pipe. In the process of reflux, water is condensed into the turbine oil, and the oil quality is emulsified, which endangers the safety production of the unit. In addition, the traditional fan only considers the installation of oil fume exhaust equipment on the main oil tank, without considering the bearing box, which makes the oil fume in the box easily accumulate and cause oil leakage of the oil baffle. Therefore, it is imperative to reform the exhaust fan.

2 Advantages of FJ series of lampblack exhaust devices
1. The whole set of equipment has good sealing performance, vertical structure, no leakage point, once and for all.
2. The output is adjustable and the P-Q curve is gentle to ensure the micro negative pressure operation of the main oil tank and bearing box.
3. The impeller and shell are made of different materials, which do not produce sparks and are durable.
4. Separate the three-level structure, completely separate the lampblack, protect the production environment and meet the requirements of civilized production.
5. The maintenance free design of the whole device can save material consumption and reduce the maintenance workload of workers.

3、 Arrangement of lampblack exhaust device
According to the actual situation, for the oil system fan, the original fan can be directly removed and installed according to our installation mode, one for standby and one for use, or two for simultaneous operation.

2. The vibration limit of fan is in accordance with JB / t8689-1998.
3. The noise limit of fan shall be in accordance with JB / t8689-1998 standard.

Note: Notes on ordering and type selection
1. For units above 100MW, one set of main oil tank and one set of bearing box are adopted. Connecting door is added in the middle of the two devices, which is conducive to the operation of the second system when one of them is under maintenance.
2. The sealing oil system of generator is equipped with explosion-proof oil fume exhaust device, one for operation and one for standby.
3. The system is a complete set of equipment, which can not be separated and refined arbitrarily, otherwise it can not achieve the desired effect.
