Description

Technical Field

[0001] The utility model relates to the technical field of turbine coolers for aviation environmental control systems, in particular to an integrated oil filling and draining and oil quantity control structure and a turbine cooler. Background Art

[0002] Turbine coolers are high-speed rotating products. Due to their high speeds, the lubrication of the bearings supporting the high-speed rotor is crucial. Turbine coolers that utilize ball bearings are typically lubricated with oil, so maintenance requires the addition and removal of lubricant. A poorly designed oil filling and draining mechanism can increase maintenance time and compromise the quality of the lubricant within the oil sump.

[0003] The amount of lubricating oil added will directly affect the bearing lubrication performance. If too little lubricating oil is added, the bearing may be poorly lubricated. If too much lubricating oil is added, it may cause the turbine cooler lubricating oil to leak. Utility Model Content

[0006] In the aforementioned integrated oil filling, draining and oil quantity control structure, both sides of the annular groove are sealed by two sealing rings.

[0007] In the aforementioned integrated oil filling, draining and oil quantity control structure, the oil filling nozzle can rotate around the axis of the oil filling and draining joint.

[0008] In the aforementioned integrated oil filling and draining and oil quantity control structure, after the oil filling nozzle is rotated into position, it is locked by a locking nut threadedly connected to the oil filling and draining joint.

[0009] In the aforementioned integrated oil filling, draining and oil quantity control structure, a washer is provided between the locking nut and the oil filling nozzle.

[0010] A turbine cooler includes a turbine cooler oil sump housing, the bottom of which is installed with the aforementioned integrated oil filling and draining and oil quantity control structure; the oil level control pipe extends into the inner cavity of the turbine cooler oil sump housing.

[0011] The advantages of the utility model are:

[0012] 1. It can effectively solve the problem that the lubricating oil in the oil pool cannot be completely discharged during maintenance of the turbine cooler that currently adopts an integrated oil filling and oil discharge structure;

[0013] 2. It can simplify the oil filling and draining operation steps during turbine cooler maintenance;

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0019] Example 1. An integrated oil filling and discharge and oil quantity control structure and turbine cooler, such as Figure 1 and Figure 2 As shown, it includes an oil filling and draining joint 5, in which a refueling channel 12 and an oil draining channel 10 isolated from each other are provided; the outlet of the oil draining channel 10 is located at the bottom end of the oil filling and draining joint 5, and is blocked by an oil draining plug 1 threadedly connected to the oil filling and draining joint 5, and the inlet of the oil draining channel 10 is located at the top end face of the oil filling and draining joint 5; the outlet end of the refueling channel 12 is located at the top end face of the oil filling and draining joint 5, and is connected to an oil level control pipe 6; the inlet end of the refueling channel 12 is communicated with an annular groove 11 provided on the side wall of the oil filling and draining joint 5, and a refueling nozzle 4 is also sleeved on the oil filling and draining joint 5 located at the annular groove 11, and the refueling nozzle 4 is communicated with the annular groove 11, and the refueling nozzle 4 is blocked by its refueling plug 7.

[0020] Both sides of the aforementioned annular groove 11 are sealed by two sealing rings 8 .

[0021] The aforementioned oil filling nozzle 4 can rotate around the axis of the oil filling and discharge joint 5.

[0022] After the aforementioned oil filling nozzle 4 is rotated into position, it is locked by the locking nut 2 threadedly connected to the oil filling and discharge joint 5.

[0023] A washer 3 is provided between the aforementioned locking nut 2 and the oil nozzle 4 .

[0024] A turbine cooler includes a turbine cooler oil sump housing 9, the bottom of which is installed with the aforementioned integrated oil filling and draining and oil quantity control structure; the oil level control pipe 6 extends into the inner cavity of the turbine cooler oil sump housing 9.

[0025] Specifically, the oil drain cap 1 is installed below the oil filling and drain joint 5 through threads; the oil filling nozzle 4 is pressed onto the oil filling and drain joint 5 through the locking nut 2 and washer 3 below. The oil filling and drain joint 5 is grooved in the middle, and the groove is sealed on both sides by two sealing rings 8; the oil level control tube 6 is welded and fixed to the oil filling and drain joint 5; the oil filling cap 7 is installed on the side of the oil filling and drain joint 5 through threads.

[0026] The entire structure is mounted on the turbine cooler oil sump housing 9 through threads and sealed by an O-ring.

[0027] When draining lubricating oil, remove drain plug 1, and all the lubricating oil in the oil sump will be discharged through the oil drain channel holes in the structure. When refilling lubricating oil, tighten drain plug 1, remove fill plug 7, and inject lubricating oil into the oil sump using a syringe. The syringe performs the filling and suction operations. The amount of lubricating oil is determined by the length L1 that the oil level control tube 6 extends into the oil sump; this length L1 is determined by the lubricating oil requirement during a maintenance cycle. Because the oil drain connector 5 has an annular groove in the center, the oil filling nozzle 4 can be rotated to the appropriate position when in use.

[0028] The specific structures of the oil filling and draining joint 5 and the oil filling nozzle 4 can be the same or different according to actual use requirements.

[0029] The oil drain plug cap 1 and the oil filling plug cap 7 may have the same or different structures depending on actual use.
