Description

Technical Field

[0001] This utility model belongs to the field of aviation fuel filter material technology, and in particular relates to a device for testing the oil-water separation efficiency of aviation fuel filter material. Background Technology

[0002] The aviation fuel filter media oil-water separation efficiency testing device is a key piece of equipment specifically designed to evaluate the performance of aviation fuel filter media. It can simulate the filter media's ability to separate free water and emulsified water from fuel under real-world operating conditions. The core components of this device include a fuel-water mixing system, a main testing circuit, a filter media testing unit, a detection module, and a data acquisition system. The fuel-water mixing system ensures uniform mixing of fuel and water through a precision proportioning pump and an ultrasonic emulsifier. However, it still has the following drawbacks in practical use:

[0003] When the aviation fuel filter material oil-water separation efficiency testing device is in operation, the testing device is directly used to support the filter material installation. However, during the operation, a lot of installation equipment and instruments are left on the workbench. During the operation, the oil stains from the test will cause pollution to the equipment. When there are many pieces of equipment, there will be many cleaning dead corners, and cleaning the testing device is not convenient.

[0004] Secondly, the testing device for the oil-water separation efficiency of aviation fuel filter materials requires the emulsion ratio to be tested in advance by other equipment. During operation, if the emulsion is added to the fuel tank of the testing device, it is easy to cause the oil in the emulsion to separate, affecting the uniformity of the emulsion and having a significant impact on the measurement accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a testing device for the oil-water separation efficiency of aviation fuel filter materials. By setting up a support platform, storage tank, constant pressure oil pump and receiving chamber, it solves the problems of inconvenient cleaning of the test platform after testing and the inability to guarantee the uniformity of the test emulsion.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a device for testing the oil-water separation efficiency of aviation fuel filter media, comprising a support platform, a storage tank, a constant pressure oil pump, and a receiving chamber. The constant pressure oil pump is located below the support platform, and the storage tank is fixedly attached to the bottom of the constant pressure oil pump. Feeding pipes are symmetrically connected to the front top of the storage tank, and connectors are fixedly connected to the top ends of both feeding pipes. Electrically controlled valves are fixed to the periphery of the feeding pipes. Receiving chambers are symmetrically located below the support platform on one side of the storage tank, and conveying pipes are fixedly connected to the top ends of both receiving chambers. During operation, the support platform supports a filter made of the filter media to be tested. The aviation fuel to be tested is stored in the storage tank. The constant pressure oil pump delivers the emulsified aviation fuel stored in the storage tank to the filter made of the filter media to be tested. The receiving chamber receives the filtered water and fuel.

[0008] Furthermore, support legs are fixed at the four corners of the bottom of the support platform, and connecting legs are fixed at the four corners of the bottom of the storage box. The support legs ensure that the support platform stably supports the test equipment, and the connecting legs independently fix the storage box to avoid vibration interference.

[0009] Furthermore, the output end of the constant pressure oil pump is fixedly connected to an oil drain pipe. Both the oil drain pipe and the delivery pipe pass through the top of the support platform. The top ends of both the oil drain pipe and the delivery pipe are fixedly connected to a second connector. The oil drain pipe delivers the emulsion to the filter input end, and the delivery pipe connects to the filter output end. The separated liquid flows into the corresponding receiving chamber, and the second connector achieves a quick sealing connection.

[0010] Furthermore, the input end of the constant pressure oil pump is fixedly connected to an oil extraction pipe, which is fixed to the top of the storage tank and extends into the drain pipe. The constant pressure oil pump draws emulsion from the bottom of the storage tank through the oil extraction pipe to maintain stable pressure.

[0011] Furthermore, a high-speed motor is fixed at the center of the bottom of the storage tank. The output shaft of the high-speed motor passes through the bottom of the storage tank and a stirring head is fixed on the output shaft. The high-speed motor drives the stirring head to rotate, forcibly mixing fuel oil and water to form a stable emulsion.

[0012] Furthermore, each of the receiving compartments is fixedly connected to a drain pipe on its lower periphery. Each drain pipe is located away from the storage tank and is positioned at a low position in the receiving compartment to facilitate the emptying of liquid. The transparent compartment and scale are used for direct reading.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient table cleaning after testing in aviation fuel filter material oil-water separation efficiency testing devices by setting up a support platform, a constant pressure oil pump, and a receiving chamber. Connecting the second connector on the drain pipe to the input end of the filter composed of aviation filter material, and connecting the second connector on the delivery pipe to the two output ends of the filter composed of aviation filter material, allows the mixture of aviation fuel and deionized water output by the constant pressure oil pump to be transported to the filter composed of aviation filter material through the drain pipe during operation. After filtration, the mixture is transported to the two receiving chambers through the two delivery pipes. This eliminates unnecessary instruments on the table of the aviation fuel filter material oil-water separation efficiency testing device, greatly improving the ease of table cleaning after testing.

[0015] This invention solves the problem of the aviation fuel filter material oil-water separation efficiency testing device being unable to guarantee the uniformity of the test emulsion by setting up a support platform, storage tank, constant pressure oil pump, and receiving chamber. After the filter composed of aviation filter material is set up on the top of the support platform, firstly, two electrically controlled valves are opened, and deionized water and aviation fuel are transported to the storage tank through the feeding pipe in a set ratio. After completion, the two electrically controlled valves are closed, and the high-speed motor is started. The high-speed motor drives the stirring head to rotate at high speed, and after the deionized water and fuel are mixed and emulsified uniformly at high speed, the constant pressure oil pump is started, and the oil is transported to the oil discharge pipe through the oil suction pipe, and then to the second connector through the oil discharge pipe, and then to the test filter through the second connector. This ensures that the test emulsion is freshly manufactured during operation, guaranteeing the uniformity of the test. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model relates to a device for testing the oil-water separation efficiency of aviation fuel filter media. It includes a support platform 1, a storage tank 2, a constant-pressure oil pump 3, and a receiving chamber 4. The constant-pressure oil pump 3 is located below the support platform 1, drawing oil from the storage tank 2 into the testing device. The support platform 1 supports the testing device. The storage tank 2 is fixed to the bottom of the constant-pressure oil pump 3, storing aviation fuel for testing. A feed pipe 201 is symmetrically fixed to the front of the top of the storage tank 2, used to transport aviation fuel and deionized fuel. Water is fed into storage tank 2. The top ends of the two feeding pipes 201 are fixedly connected to connectors 203. The feeding pipes 201 are connected to the installed equipment and are connected to the equipment for conveying aviation fuel and deionized water through connectors 203. An electric control valve 202 is fixed on the periphery of the feeding pipe 201. The feeding pipe 201 controls the flow of the feed through the electric control valve 202. A receiving chamber 4 is symmetrically arranged below the support platform 1 on one side of storage tank 2. The top ends of the two receiving chambers 4 are fixedly connected to conveying pipes 402. The two receiving chambers 4 receive the separated water and fuel respectively.

[0026] Specifically, support legs 101 are fixed at the four corners of the bottom of the support platform 1, and connecting legs 206 are fixed at the four corners of the bottom of the storage box 2. When the support platform 1 is working, it is supported on the ground by the support legs 101, and the storage box 2 is supported on the ground by the connecting legs 206.

[0027] Furthermore, the output end of the constant pressure oil pump 3 is fixedly connected to an oil drain pipe 302. Both the oil drain pipe 302 and the delivery pipe 402 pass through the top of the support platform 1. The top ends of the oil drain pipe 302 and the delivery pipe 402 are fixedly connected to a connector 303. The oil drain pipe 302 at the output end of the constant pressure oil pump 3 delivers fuel to the filter composed of the filter material to be tested. The connector 303 on the oil drain pipe 302 connects the oil drain pipe 302 to the input end of the filter composed of aviation filter material, delivering the aviation fuel mixed with water and emulsified into the filter composed of aviation filter material. The connector 303 on the delivery pipe 402 is connected to the two output ends of the filter composed of aviation filter material, so that water and fuel are output separately during operation.

[0028] The operation process of this embodiment is as follows: During operation, the second connector 303 on the oil drain pipe 302 is first connected to the input end of the filter composed of aviation filter material, and the second connector 303 on the conveying pipe 402 is connected to the two output ends of the filter composed of aviation filter material respectively. This allows the mixture of aviation fuel and deionized water output by the constant pressure oil pump 3 to be conveyed to the filter composed of aviation filter material through the oil drain pipe 302 during operation, and after filtration, it is conveyed to the two receiving chambers 4 through the two conveying pipes 402 respectively. Specific Implementation Example 2

[0029] Please see Figure 1-5 Based on the first specific embodiment, the input end of the constant pressure oil pump 3 is fixedly connected to the oil extraction pipe 301. The oil extraction pipe 301 is fixed to the top of the storage tank 2 and extends into the oil discharge pipe 302. When the constant pressure oil pump 3 is working, the oil mixed with deionized water in the storage tank 2 is extracted through the oil extraction pipe 301.

[0030] Specifically, a high-speed motor 204 is fixed at the center of the bottom of the storage tank 2. The output shaft of the high-speed motor 204 passes through the bottom of the storage tank 2 and a stirring head 205 is fixed on the output shaft. The high-speed motor 204 at the bottom of the storage tank 2 drives the stirring head 205 to rotate inside the storage tank 2. Through the rotation of the stirring head 205, aviation fuel and deionized water are driven to rotate at high speed and emulsify and mix.

[0031] Furthermore, each receiving chamber 4 is fixedly connected to a drain pipe 401 on its lower periphery. The receiving chamber 4 is transparent and has scales printed on its surface. Each drain pipe 401 is located away from the storage tank 2. The end of the drain pipe 401 on the receiving chamber 4 that is away from the receiving chamber 4 is connected to the equipment that discharges water or fuel oil.

[0032] The operation process of this embodiment is as follows: During operation, after the filter composed of aviation filter material is set on the top of the support platform 1, firstly, open the two electronically controlled valves 202, and then deliver deionized water and aviation fuel to the storage tank 2 through the feed pipe 201 in a set ratio. After completion, close the two electronically controlled valves 202, start the high-speed motor 204, and drive the stirring head 205 to rotate at high speed. After the deionized water and fuel are mixed and emulsified evenly at high speed, start the constant pressure oil pump 3, and deliver the oil to the oil discharge pipe 302 through the oil suction pipe 301, and then through the oil discharge pipe 302. 02 is delivered to connector 2 303, and then to the test filter. After filtration in the filter, the filtered oil and water are delivered to two delivery pipes 402 and then to two receiving chambers 4. After the liquid output stabilizes, the constant pressure oil pump 3 is turned off first, and then the liquid level in the two receiving chambers 4 is read. The constant pressure oil pump 3 is then started and turned off after the set time. The liquid level in the two receiving chambers 4 is recorded, and the difference in liquid level before and after is determined. This allows us to know the filtration efficiency of the filter material within a given time. The oil drain pipe 302 and the two delivery pipes 402 are all flexible hoses.
