Titanium fan 9-38

Summary
Y9-38- Y8-39 single suction boiler fan, although the old model, but the life of the fan is considerable. The utility model is mainly suitable for the 2t/h~230t/h and the steam passage system of the steam boiler. The basic model of the fan is "9-35", the model of the induced draft fan is Y9-35:
9 - Fan said at the highest efficiency (ETA max) when the total pressure coefficient by 10 after the integer.
35 - Fan said at the highest efficiency (max) than the integer number.
Y indicating fan.
Single suction fan to add a model of "11" or "12", where the first digit of the single suction on behalf of the figure, the number of second for the design order number.
The basic machine number is No6D, 8 D, 10 D, 12 D, 13.5 D, 15.5 D, 18 D, 20 D and 13.5F, 15.5 F, 18 F, 20 F, a total of 21.5 F, two kinds of transmission. If the machine number and transmission mode can not meet your requirements, we have the ability to design and manufacture non-standard products to meet your production needs.
From the direction of the motor to face the impeller, clockwise rotation, said the right whirlwind machine, to "right" means, on the contrary, said the left whirlwind machine to "left".
Structure
The utility model is mainly composed of an impeller, a casing, an air inlet, a transmission group and an adjusting door.
The impeller is composed of a front curved blade, a conical wheel cover and a flat rear plate, which are riveted on the shaft plate, and the maximum speed of the impeller can reach 80m/s.
The shell is welded by steel plate into the volute, made the whole structure of No6~No12 fan, No13.5 type the above casing is arranged on the top of 1/4 casing can be opened, so that the loading and unloading of impeller.
Drive spindle is made of high-quality steel, single suction fan adopts rolling bearing, the bearing box is equipped with a thermometer and oil level indicator to indicate the amount of gas and bearing temperature.
The door is made of ordinary steel plate, which is used to adjust the air volume and control the motor load.
Fan installation
1, before installation should be based on the concrete foundation dimensions of design and manufacture of wind turbine and motor, manufacture and installation of necessary spare parts and tools, such as anchor bolts, safety cover etc..
2, the Ministry should carefully check before installation, cleaning, cleaning, and cleaning with kerosene bearings and bearing box, add lubricating oil, if damaged, should be repaired.
3, the first installed on the basis of the casing, pay attention to the weight of the pipeline and heat expansion and load should not be added to the chassis.
4, remove the removable parts of the chassis, and then the impeller and the transmission part is installed on the basis, in accordance with the requirements of the gap size, and maintain the level of the shaft.
5, in the fan inlet, if not connected to the pipeline, should be equipped with barbed wire, the wire by the user.
6, installation of the motor, the motor shaft and the fan shaft concentric shaft nonconcentricity 0.05~0.1 mm.
7, coupling should be added safety cover, safety cover by the user according to the actual situation of the design and manufacture.
Fan operation
1, before the start of the machine, should do the following preparations:
The closed air inlet damper, outlet damper slightly open.
We check the machine parts clearance, the rotating part does not allow Guaceng, all parts should be fixed tightly.
Check whether the installation of reliable coupling.
Check the electrical lines and instrument is correct.
Check the impeller rotation direction is consistent with the label.
2, motor starting equipment, users should be based on the actual situation, decide whether or not to use.
3, in the operation of the fan system, pay close attention to have the same sound, different earthquakes, odor and other abnormal phenomena, such as should be excluded.
4, to be transported to the normal speed, gradually open air damper, and the air damper, until it meets the specified load so far.
5, the machine running after 1~2 hours, check the bearings and other parts of the car, and then run 6~8 hours, if the situation is normal, can be delivered to the acceptance.
6, the bearing temperature should not exceed 40 degrees
7, parking should be carried out in the following order:
The closed air inlet damper, outlet damper slightly open.
The closed motor in accordance with the procedures.
8, under the circumstances, must immediately stop check.
Has the intense noise
The bearing temperature rises sharply.
The body vibration or impact.
Fan maintenance
The fan and the system to stop the operation.
The fan should be kept by hand and used by others.
Regularly remove dust, dirt and other impurities inside the fan, and prevent rust.
Maintenance of the wind turbine must be carried out in stopping power.
The wind machine maintenance, commissioning and prohibit children related to personnel and the disabled the presence of onlookers.
The fan test station, in the fan direction within ten meters to import and export.
Before and after the wind machine maintenance shall be counted tools and other products, to prevent the left in the fan and the internal pipeline.
Main faults and causes of fan
1, bearing box vibration
The fan shaft and the motor shaft coupling, loaded askew;
Casing and impeller or air inlet and impeller friction;
The stiffness of the foundation is not strong enough;
The impellerrivet loose or impeller deformation;
The impeller shaft and the shaft with loose plate hole;
The casing and the bearing box and a bracket, bearing and bearing box cover connecting bolt looseness;
Inlet and outlet pipe installation, bad fan, resonance;
The rotor imbalance;
To fan blade wear.
2, bearing temperature rise too high
Bearing box vibration;
Poor quality of lubricant
