Introduction

Aircraft Engine Bleed Air System Test Equipment (P/N: PAC30P300P4T-S)  is applied to Boeing series (737-600/700 / 800/900)  Aircraft Engine Bleed Air System  Components Health Checking (based on components AMM manual). It is  a powerful and troubleshooting tool for checking  components in the wings and  off the wings.Configuring different adapter can also apply to other models.

Test Content:

1)Check air-entraining regulator control pressure  (Pc)
2) Check air-entraining regulator over-pressure switch working in the appropriate pressure range
3) Check  pressure regulator shut-off valve to open in the minimum supply pressure (Ps)
4) Check  precooler control valve to close in the minimum supply pressure (Ps)
5) Check  precooler control valve to provide a suitable control pressure (Pc)
6) Check precooler control valve to adjust in accordance with the control pressure (Pc) changes   in  control pressure changing.
7) Check High-pressure regulator to control pressure (Pc)
8) Check High-pressure valve to work properly
9) Check High-pressure regulator reflux checking protection to work properly
10) Check sensing tube without leakage

Alt Part Number:

SPL-4350(P/N:C36001-44)   ENGINE BLEED AIR SYSTEM TEST SET
SPL-922(P/N:3792195-1)     ENGINE BLEED AIR SYSTEM TEST SET

Main Parameters??

Nitrogen pressure reducer : (input)1500PSI??2000PSI  (output)0??400 PSI
Ps port output pressure range??0-150 PSI
High-pressure gas hose: For high-pressure gas, good bending performance, length: 4m; internal diameter: 6mm ;ID Working pressure: 500 PSI

 

Support Requirements:

Using this equipment, users need to independently provide the following auxiliary equipment:
High-pressure nitrogen bottles: V>10 L, pressure range:1500-2000 PSI,    output port??G5/8?¨M??
Size:   L:660 mm X W:500 mm X H:340 mm
Weight??18 Kg

Advantages:

1, all measuring instruments and operating switches are installed in a panel.it has very convenient man-machine interface,the clarity of test operations and it is reflecting the test process. The innovative and unique design of the operation panel is greatly conducive to test operations personnel operating accurately in accordance with the provisions of the correct operation. it need not  to  the instrument assembly and other auxiliary processes when using.

2, the modular interface adapter and the adapter connection convenient and flexible with the aircraft bleed air system, reducing the assembly and disassembly of the aircraft side, the use of more convenient and reliable. Configure different interface adapter and the adapter function of the equipment for a variety of models, expansion powerful.

3, the test interface adapters and test hoses connected to quick release mode, so that the test connection reliable and convenient, greatly reducing the intensity of work and saving time and greatly improved work efficiency.

4 gauge measurements using high-precision digital pressure gauge, with intuitive display, large range, high precision performance characteristics. Without having to switch in the test range to avoid the use of over-voltage caused by damage to the instrument, reduce the amount of work pressure.

5, the pressure output of the device using two-way independent adjustment mode, as opposed to the BOEING recommended equipment, with better accuracy and the ability to regulate, has multiple redundant to adjust the pressure output capability.

6, have to meet the testing requirements of the differential pressure gauge, manual testing methods, which fully meet the AMM. BOEING recommended equipment used, the basic non-configure the instrument, can not fully meet the requirements of health checks.

7, the complete package of equipment, accessories, compact and solid, safety equipment boxes and aviation integration rod with a pulley. Use customers only need to provide the nitrogen bottles, convenient transportation to bring great convenience for the operator.

8, on the basis of full compliance with the requirements in accordance with the AMM manual, combined with the airlines row so the experience and statistical analysis of data, the use and operation of the device PAC30P300P4T-S has a simple, reliable, efficient
