Preparation for Test7.1 Mount the vacuum cleaner motor/fan system unit to the plenum chamber by any convenient method meeting therequirements of 7.1.1 7.1.5.1. See Fig. 1 for an example of a motor mounted to the plenum chamber.7.1.1 The motor/fan sys
35、tem inlet shall be centered with respect to the outlet opening of the plenum chamber.7.1.2 The motor/fan system inlet shall be mounted to the plenum chamber such that the inlet does not project into the plenumchamber.7.1.2.1 If necessary, mount the motor/fan system to a standoff pipe, having an insi
36、de diameter of 4 in. and suitable length toprevent the motor/fan system inlet from projecting into the plenum chamber. See Fig. 2 for an example.7.1.3 Secure the motor/fan system unit to the plenum chamber such that it does not rotate when the motor starts.7.1.4 Seal all leaks between the motor/fan
37、system inlet and the plenum chamber by any convenient means. See Fig. 3 forexample of mounting gasket and plate used to create a seal.7.1.5 For vacuum cleaner motor/fan systems requiring a part from the vacuum cleaner housing to complete the fan chamber,it is acceptable to mount the motor/fan system
38、 to this part and in turn mount the fan chambers inlet to the plenum chamber.7.1.5.1 It may be necessary to modify the vacuum cleaner housing by any convenient means to allow the fan chamber inlet tobe mounted per 7.1 7.1.4. The modifications shall not affect performance.7.2 Connect the motor/fan sy
39、stem to the power supply using a length of cable of sufficient size to maintain rated voltage at themotor/fan system electrical terminals.7.3 Set the manometers to zero and check all instruments for proper operation.FIG. 1 Motor Mounted to Plenum ChamberF2105 1737.4 Record the test station pressure

Test Procedure8.1 Operate the vacuum cleaner motor/fan system with no orifice plate inserted in the plenum chamber inlet at nameplate ratedvoltage 61 % and frequency 61 Hz for 1 h prior to the start of the first test run. For vacuum cleaner motor/fan systems with dualnamepla
42、te voltage ratings, conduct testing at the highest voltage.8.2 For each subsequent test run, allow the unit to reach its normal operating temperature by allowing the vacuum cleanermotor/fan system to operate at the open orifice for 1 to 2 min between test runs.8.3 While operating the vacuum cleaner
43、motor/fan system per 8.2, insert orifice plates sequentially into the orifice plate holderof the plenum chamber starting with the largest size orifice and following it with the next smaller orifice plate. Use the followingorifice plates: 2.0, 1.5, 1.25, 1.0 0.875, 0.75, 0.625, 0.5, 0.375, 0.25 and 0

(63.5, 57.2, 44.5, 34.9, 28.6 mm).8.4 For each orifice plate, record the suction, h, and input power, P, in that order. All readings should b
45、e taken within 10 s ofthe orifice insertion. For orifices less than 0.750 in., allow the vacuum cleaner motor/fan system to operate at the open orifice for1 to 2 min before inserting the next orifice.FIG. 2 Example of Standoff PipeFIG. 3 Mounting Plate and GasketF2105 1748.4.1 Read the suction to th
46、e nearest graduation of the manometer. Readings should be taken as soon as the manometer reachesa true peak. (When using a fluid type manometer, the liquid level may peak, drop, and peak again. The second peak is the truepeak reading. A person conducting the test for the first time shall observe at
47、least one run before recording data. See SpecificationF431 for instructions on how to minimize the overshoot (first peak) of the liquid level.)9.
