Inspection Equipments For Fuze 447

INSPECTION OF FUZE FFV 447 for 84MM HE:

1) Spin test of CWM (1300-3500 RPM):

PROGRAMMABLE SPINNING EQUIPMENT FOR CLOCKWORK:

General description:

This programmable spinning equipment is specially developed to spin Clockwork mechanism. The Operator has to load CWM in the adaptor manually & press the Test Start switch. The Adaptor will start rotating to attain the speed of 3500 RPM. While attaining speed of 3500 RPM the arming RPM will be recorded on display. A sophisticated suitable PLC and VFD combination is used to achieve desired results.

Technical Specifications:

Operating Voltage : 240 V AC + / - 10%, 50 Hz.

Speed control : by variable frequency drive.

Speed Indication : 0 – 4000 RPM.

Direction : Anticlockwise.

Spinning weight : Less than 100 gm.

Accuracy of speed : + / - 2 % of FS.

Indication & control : By lamps and switches.

test time : 1 min. approx.

Dimensions : 800 (W) X 1300 (H) X 1000 (D) mm max. Floor mounting type.

2) Arming delay time test of DSD (0.100 to 0.200 Sec.) at 5000 RPM:

PROFGRAMMABLE DELAY TIME TESTING EQUIPMENT FOR DSD:

General description:

This spinning equipment is specially developed to test Delay time at controlled RPM. The Operator has to load DSD in the adaptor manually & press the Test Start switch. The Adaptor will start rotating to attain the speed of 5000 RPM. After attaining speed of 5000 RPM, a Pin inside will be retracted automatically to allow the rotor to rotate. The millisecond counter will be started to record Delay time till arming / completion of the rotor movement. A sophisticated suitable PLC and VFD combination is used to achieve desired results.

Technical Specifications:

Operating Voltage : 240 V AC + / - 10%, 50 Hz.

Speed control : by variable frequency drive.

Speed Indication : 0 – 5000 RPM.

Direction : Anticlockwise.

Spinning weight : Less than 100 gm.

Accuracy of speed : + / - 2 % of FS.

Indication & control : By lamps and switches.

Maximum test time : 1 min. approx.

Dimensions : 800 (W) X 1300 (H) X 1000 (D) mm max. Floor mounting type.

Millisecond Indication : 0 – 999 milli seconds.

3) Function of centrifugal acceleration test (1400 & 4000 ‘g’):

PROGRAMMABLE CENTRIFUGAL ACCELERATION TEST EQUIPMENT FOR DSD:

General description:

This centrifuge equipment will be specially developed to test arming for two different Centrifugal Accelerations. The operator has to load DSD in the adaptor manually & press the Test Start-1 switch. The turn table will start rotating to attain the 1400 ‘g’ (first presetted speed). This speed will be maintained to check the product for this first presetted ‘g’ value for non-arming. After visual inspection, the test can be further continued by pressing Test Start-2 to attain the second 4000 ‘g’ (second presetted speed). Again this speed will be maintained to check product for this second presetted ‘g’ value for arming. A rotary turntable driven by electrical motor & sophisticated variable frequency drive is used for this equipment. The total test is controlled by dedicated instruments. The four units of DSD can be installed at a time being a rotary turn table. A sophisticated suitable VFD is used to achieve desired results.

Technical Specifications:

Operating Voltage : 415 V AC + / - 10%, 50 Hz, 3 phase 4 wire with earth.

Speed control : by variable frequency drive.

Speed Indication & range : 0 – 5000 RPM .

Direction : Anticlockwise.

Spinning weight : Less than 100 gm.

Accuracy of speed : + / - 2 %.

Indication & control : By lamps and switches.

Maximum test time : 2 min approx.

G range : 1400 & 4000 ‘g’.

Dimensions : 800 (W) X 1300 (H) X 1000 (D) mm max. Floor mounting type.
