Description

Technical Field

[0001] This utility model relates to a screw-driven onboard oil pump separation technology specifically for onboard environments, and to a screw-driven onboard oil pump core and housing separator, which is a disassembly tool for pump cores and housings that are difficult to separate from onboard fuel systems and hydraulic systems. Background Technology

[0002] Aviation fuel pumps play a crucial role in aircraft fuel systems, primarily functioning to pressurize fuel in fuel tanks and deliver it to the aircraft engines. However, due to limitations imposed by laboratory space layout and production assembly coordination, traditional disassembly methods lack convenient tooling and safe disassembly space. When analyzing and troubleshooting fuel and hydraulic system failures, problems often arise such as the difficulty in disassembling fuel pumps and the significant manpower and time costs associated with separating the pump core and housing.

[0003] Traditional disassembly methods have certain drawbacks and safety hazards, specifically:

[0004] (1) The on-board testing environment lacks dedicated equipment. During disassembly, the methods and tools used by operators are inconsistent, making it difficult to ensure effective protective measures. Disassembly can lead to a series of problems, such as difficulties in loading and unloading, large space occupation, and damage to finished products caused by forced disassembly, which seriously affect the on-board testing environment, the safety of finished products, and the safety of personnel.

[0005] (2) Traditional disassembly methods often rely on manual labor, which is highly unstable. During the disassembly process, problems such as leakage of aviation fuel and hydraulic oil are common. Because aviation fuel is volatile and flammable, it can even cause a fire when its concentration in the air reaches a certain level, resulting in a major accident and making it difficult to ensure the safety of the onboard environment and production.

[0025] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , 2 As shown in Figures 1 and 3, this utility model provides a screw-driven onboard oil pump core and housing separator, including a separator housing 1, a pump core disassembly and assembly module 2, a screw drive device 3, a drive handle 4, and an isolation device 5.

[0027] The threaded drive device 3 is connected to the upper surface 7 of the pump core disassembly and assembly module. The pump core disassembly and assembly module 2 is provided with a pump core disassembly and assembly module contact groove 6, which is used to connect the pump core and the pump core and pump shell separator together when separating the pump core and pump shell.

[0028] The threaded drive unit 3 and the pump core disassembly module 2 are installed in the separator housing 1. A drive handle 4 is installed on the rear plate of the separator housing 1. The threaded drive unit 3 is moved up and down by the drive handle 4 to provide power to the pump core disassembly module 2. The separator housing 1 is fixed to the pump housing by a fixing device to reduce vibration when the pump core and pump housing are separated and to ensure that the oil does not spill out.

[0029] The separator housing 1 is cylindrical in shape, with an isolation space formed by insulating rubber on the bottom surface. A drive handle 4 is installed on the top surface of the housing. The drive handle 4 is connected to a threaded drive device 3 inside the housing. A pump core disassembly module 2 is fixed to the base of the threaded drive device 3. The vertical adjustment is achieved by rotating the drive handle 4 to control the rotation of the threaded drive device 3. During disassembly and assembly, the pump core disassembly module 2 is connected to the pump core, and the pump core is disassembled by rotating the threaded drive device 3.

[0030] The isolation device 5 is connected to the separator housing base and matches the shape of the fuel pump housing on the machine. The pump core disassembly module 2 is fixed to the bottom of the threaded drive device 3 and matches the shape of the fuel pump core on the machine.

[0031] The separator housing 1, pump core disassembly module 2, drive handle 4, and threaded drive device 3 are made of stainless steel.

[0032] The material of the isolation device 5 is rubber.

[0033] The threaded drive device 3 is connected to the drive handle 4 at its end. When disassembling the pump core, the drive handle 4 rotates the threaded drive device 3 to provide power for disassembling the pump core. The pump core disassembly / assembly mold 2, after being connected to the threaded drive device 3, is located inside the separator housing 1. An isolation device 5 is installed at the bottom of the separator housing 1 to isolate fuel leaked during pump core separation. A fixing groove 8 is designed at the bottom of the separator housing 1 to fix the pump core / mass separator to the pump core during pump core / mass separation, ensuring the stability of the equipment.

[0034] Now combined Figure 1 The specific implementation of this patent is described below.

[0035] When separating the pump core and pump housing on the machine, connect the contact groove 6 of the pump core disassembly module inside the separator to the pump core handle. Align the fixing groove 8 at the bottom of the separator housing with the U-shaped groove on the pump housing, and fix the separator to the pump housing with screws. Check the isolation device 5 to ensure sealing. Rotate the drive handle 4 to provide an upward force to the threaded drive device 3. This will cause the pump core to separate from the pump housing. After separating the pump core, wipe the isolation device 5 dry. Remove the on-machine oil pump separator 1 from the pump housing.
