PTR训练教材液压油箱勤务 编号：08-B737-06A/P TYPE: B737CLA. General(1) If the complete loss of hydraulic fluid has occured, accomplish Hydraulic Fluid Replacement procedure.(2) If the hydraulic reservoir was filled after the replacement of a component or after fluid loss, accomplish Bleed the Hydraulic System procedure.(3) The equipment that is necessary to fill the hydraulic fluid is on the forward bulkhead of the right wheel well. The equipment includes a hand pump, a pressure fill connection, a filter for the hydraulic fluid, and a selector valve.(4) There is a fluid quantity indicator on the system A and B reservoirs. The system B reservoir is filled through the standby reservoir. When the fluid quantity indicator for system B shows full, the system B reservoir and the standby reservoir are full.(5) The fluid chilling at high altitude and the large ambient temperature changes between departure and arrival locations can result in a decrease in fluid levels. These cold soak effects will not have an impact on the operation of the systems but it can shrink the fluid sufficiently to indicate a need for servicing, even if you serviced the reservoirs at a warm location before the previous flight. Under such circumstances, if you service the airplane high at the cold location before the airplane is sent back to the warm location, it is possible that you will cause an overfill of the reservoir and fluid can overflow from the drain line.(6) If the ambient temperature on the ground is 20 F or lower at an arrival location and a fluid level is below REFILL, service the reservoir to just above REFILL to avoid the overflow of fluid at the next warmer location.B. Hydraulic Reservoir Servicing ProcedureStep-1 Remove hydraulic power (WARNING-1).Step-2 Make sure the flaps and the leading edge devices are up.Step-3 Before you fill the system B reservoir, make sure the brake accumulator has a minimum of 2800 psi of pressure in it (with the hydraulic pumps off).Step-4 If you use the hand pump, put the end of the suction hose in the hydraulic fluid container.(WARNING-2,-3)Step-5 If you use a service cart, connect the hose from the service cart to the pressure fill connection.Step-6 Turn the selector valve to the reservoir to be filled.(WARNING-4,-5,-6)Step-7 Add hydraulic fluid until the indicator on the reservoir shows FULL.Step-8 Put the selector valve in the CLOSED position.Step-9 Put the handle and the filler hose for the hand pump in their usual positions, or disconnect the pressure cart.Step-10 Look at the gages, for the hydraulic fluid quantity, Make sure the gages show the hydraulic fluid quantity is above refill.C. Directions:WARNING-1: It is not necessary to remove the air pressure from the hydraulic reservoirs before you fill them.WARNING-2: All currently qualified BMS 3-11, Type IV hydraulic fluids are interchangeable and intermixable in any proportion.WARNING-3: DO NOT SUPPLY HYDRAULIC FLUID AT MORE THAN 75 PSI TO THE PRESSURE FILL CONNECTION. A PRESSURE OF MORE THAN 75 PSI CAN CAUSE DAMAGE TO THE HYDRAULIC SYSTEM.WARNING-4: PORT A fills reservoir A, and PORT B fills the standby reservoir and reservoir B.WARNING-5: DO NOT GET HYDRAULIC FLUID ON YOU. HYDRAULIC FLUID, BMS 3-11 CAN CAUSE INJURY TO PERSONS. IF YOU GET THE HYDRAULIC FLUID ON YOUR SKIN, FLUSH YOUR SKIN WITH WATER. IF YOU GET THE HYDRAULIC FLUID IN YOUR EYES, FLUSH YOUR EYES WITH WATER AND GET MEDICAL AID. IF YOU EAT OR DRINK THE HYDRAULIC FLUID, GET MEDICAL AID.WARNING-6: USE CLEAN HYDRAULIC FLUID AND CLEAN EQUIPMENT WHEN YOU FILL THE THE HYDRAULIC RESERVOIRS. DIRT CAN CAUSE DAMAGE TO THE HYDRAULIC SYSTEM.-END OF TASK-A/P TYPE: B737NGA. General(1) The equipment that is necessary to fill the hydraulic fluid is on the forward bulkhead of the right wheel well. The equipment includes a reservoir manual fill pump, a pressure fill connection, a reservoir fill filter module for the hydraulic fluid, and a reservoir fill selector valve.(2) There is a fluid quantity indicator on the system A and B reservoirs. The standby reservoir is filled through the B system reservoir. When the fluid quantity indicator for system B shows full, the system B reservoir and the standby reservoir are full.(3) The fluid chilling at high altitude and the large ambient temperature changes between departure and arrival locations can result in a decrease in fluid levels. These cold soak effects will not have an impact on the operation of the systems but it can shrink the fluid sufficiently to indicate a need for servicing, even if you serviced the reservoirs at a warm location before the previous flight. Under such circumstances, if you service the airplane high at the cold location before the airplane is sent back to the warm location, it is possible that you will cause an overfill of the reservoir and fluid can overflow from the drain line.(4) If the ambient temperature on the ground is 208 F (-68C) or lower at an arrival location and a fluid level is below REFILL, service the reservoir to just above REFILL to avoid the overflow of fluid at the next warmer location.B. Hydraulic Reservoir ServicingStep-1 Make sure the flaps and the leading edge are up.Step-2 Remove power from hydraulic systems A, B and the standby systems(WARNING-8):Step-3 Before you fill the system B reservoir, make sure the brake accumulator has a minimum of 2800 psig (19305 kPa) of pressure in it (with the hydraulic pumps off).Step-4 If you use the hand pump, put the end of the suction hose in the 5 gallon (19 liters) hydraulic fluid resistant container, STD-1110 (WARNING-9).Step-5 If you use a servicing cart, COM-1537 connect the hose from servicing cart, COM-1537 the to the pressure fill connection.Step-6 Turn the reservoir fill selector valve to the reservoir to be filled (WARNING-10,-11,-12,-13).Step-7 Fill the hydraulic reservoir until the quantity indicator on the side of the reservoir shows that the fluid level is nearer F (full) than RFL (refill) and is approximately two-thirds of the indication sweep between RFL and F (WARNING-14, -15, -16).Step-8 Put the reservoir fill selector valve in the CLOSED position.Step-9 Put the handle and the suction hose for the hand pump in their usual positions, or disconnect the servicing cart, COM-1537.Step-10 Look at the gages. Make sure the gages show the hydraulic fluid quantity are above refill (greater than 76%).C. Dirctions:WARNING-8: It is not necessary to release pressure from the hydraulic reservoirs before you fill them.WARNING-9: DO NOT SUPPLY HYDRAULIC FLUID AT MORE THAN 75 PSIG (517 KPA) TO THE PRESSURE FILL CONNECTION. A PRESSURE OF MORE THAN 75 PSIG (517 KPA) CAN CAUSE DAMAGE TO THE HYDRAULIC SYSTEM.WARNING-10: PORT A fills reservoir A, and PORT B fills the standby reservoir and reservoir B. WARNING-11: PUT THE CORRECT QUANTITY OF FLUID IN THE HYDRAULIC RESERVOIR. IF THERE IS TOO MUCH FLUID, IT GOES INTO THE PNEUMATIC DUCTS AND THE AIR CONDITIONING PACKS. THIS CAUSES SMOKE AND FUMES THAT GO INTO THE FLIGHT COMPARTMENT AND PASSENGER COMPARTMENT. HYDRAULIC FLUID CONTAMINATION OF THE PNEUMATIC SYSTEM CAN ALSO CAUSE DAMAGE TO TITANIUM DUCTS. SMOKE AND FUMES FROM HYDRAULIC FLUID CAN CAUSE INJURIES TO PERSONNEL.WARNING-12: DO NOT GET HYDRAULIC FLUID ON YOU. HYDRAULIC FLUID, BMS 3-11 CAN CAUSE INJURY TO PERSONS. IF YOU GET THE HYDRAULIC FLUID ON YOUR SKIN, FLUSH YOUR SKIN WITH WATER. IF YOU GET THE HYDRAULIC FLUID IN YOUR EYES, FLUSH YOUR EYES WITH WATER AND GET MEDICAL AID. IF YOU EAT OR DRINK THE HYDRAULIC FLUID, GET MEDICAL AID.WARNING-13: USE CLEAN HYDRAULIC FLUID AND CLEA
