Description

Technical Field

[0001] The invention relates to the technical field of fuel oil quality detection, in particular to a quality detection device for aviation fuel oil. Background Art

[0002] The main reasons for testing aviation fuel for mechanical impurities include ensuring product quality and ensuring equipment safety. Mechanical impurities (such as metal particles, sand, etc.) can cause serious damage to equipment and engines. These impurities may clog filters and injectors, causing abnormal fuel supply, and in severe cases even interrupting fuel supply, affecting the normal operation of the aircraft. In addition, mechanical impurities can also increase the wear of friction surfaces, affect the lubrication effect, and further threaten the safety of the aircraft.

[0003] However, when filtering mechanical impurities in fuel oil through a measuring instrument, the operator generally pours the oil to be tested into a funnel through a measuring cup. When a large amount of oil is poured at one time, since it takes a certain amount of time to filter the oil, excess fuel oil may flow onto the measuring instrument and adhere to the equipment, which is not conducive to subsequent cleaning and is likely to affect the test results of the fuel oil. In addition, after the oil in the funnel is filtered, the operator needs to add oil to the measuring cup and add the oil to the funnel again. The manual repeated addition work steps are cumbersome and inefficient, which is not conducive to improving the detection speed of different types of fuel oils. Summary of the invention

The temperature control plate is snap-fitted onto the impurity measuring instrument body. The temperature control plate is fixedly connected to a connecting rod. The connecting rod is fixedly installed with a fixed block. A card slot is provided in the impurity measuring instrument body.

A vacuum pump exhaust pipe is fixedly installed on the impurity measuring instrument body, and the vacuum pump exhaust pipe is connected to the bent pipe. A rubber plug is snap-fitted on the top of the suction bottle, and a funnel is snap-fitted on the rubber plug. The funnel is connected to the interior of the suction bottle, the funnel is snap-fitted to the temperature control plate, and the oil filling pipe is connected to the interior of the funnel.

[0010] Specifically, the main structure includes a baffle and a measuring cup. The baffle and the control screen are fixed on the impurity measuring instrument body. The measuring cup is placed on the impurity measuring instrument body. The impurity measuring instrument body is rotatably connected to a box door. Two sets of mounting blocks are fixedly installed on the impurity measuring instrument body, and a clamping plate is slidably connected to the mounting blocks.

[0011] The beneficial effects of the present invention are:

[0012] (1) The quality inspection device for aviation fuel oil described in the present invention installs a heating mechanism inside the impurity measuring instrument body, and then snaps the filter mechanism into the heating mechanism, so that the fuel oil placed in the filter mechanism can be heated and controlled at a temperature, that is, the operator first snaps two temperature control boards into two slots provided at the top of the impurity measuring instrument body. Since the temperature control boards are arranged in an inclined structure, when the operator puts the funnel into the temperature control board, the funnel can be brought into contact with the inner wall of the temperature control board, and then the temperature control board can be used to control the temperature and heat the fuel oil detected in the funnel in the subsequent experimental process. ; Then, the rubber stopper is put on the side wall of the funnel from the bottom end, and then the rubber stopper is snap-connected with the suction bottle placed on the heating plate. When the rubber stopper contacts the bottle mouth of the suction bottle, the interior of the suction bottle can be sealed; a bent pipe is installed on the suction bottle, and a vacuum pump is provided inside the impurity measuring instrument body. The vacuum pump exhaust pipe is installed on the side wall of the impurity measuring instrument body and is connected with the interior of the vacuum pump. The end of the vacuum pump exhaust pipe facing away from the impurity measuring instrument body is put on the end of the bent pipe, so that the vacuum pump exhaust pipe can be connected with the interior of the suction bottle through the bent pipe, thereby facilitating the installation of the detection tool before detection.

[0013] (2) The quality inspection device for aviation fuel oil described in the present invention can position the feeding mechanism by placing it on the supporting mechanism, and then store the lubricating oil by placing it in the feeding mechanism, that is, two sets of fixing rods are fixed to the top of the impurity measuring instrument body, and the tops of several fixing rods are fixedly connected to the supporting ring. The cylinder is inserted into the mounting groove provided in the supporting ring, and the cylinder can be supported when the bottom end of the cylinder contacts the inner wall of the supporting ring; after the fuel oil to be used for inspection is placed in the cylinder, the cylinder cover can be rotated to seal the top of the cylinder to prevent dust or other impurities from easily entering the fuel oil when the top of the cylinder is in an open state, and it is also convenient to store the fuel oil through the cylinder.

[0014] (3) The quality inspection device for aviation fuel oil described in the present invention can set the experimental parameters through the main body mechanism. During the inspection, the feeding mechanism is rotated to add the lubricating oil to the filtering mechanism, which reduces the operator's work steps of repeatedly pouring oil and prevents the situation where too much oil is poured at one time, causing the oil to flow onto the measuring instrument and become difficult to clean. That is: according to the fuel oil to be tested, the switch of the impurity measuring instrument body is turned on, and its test parameters or sample numbers can be set through the control screen; during the inspection, the filter paper with constant weight can be put into the funnel first. After the fuel oil is stored in the cylinder, the oil at the bottom of the cylinder can be discharged into the interior of the funnel through the oil filling pipe. When the oil filling pipe does not discharge the oil and the amount of oil in the funnel decreases, the operator can rotate the rotating block by hand. The rotating block is fixedly connected to the screw rod. When the rotating block drives the screw rod to rotate, the screw rod can be rotated along the inner wall of the cylinder cover. The screw rod and the cylinder cover are threadedly connected, and a sealing block is installed at the bottom end of the screw rod. When the screw rod drives the sealing block to move in the direction close to the cylinder cover, the sealing block can be separated from the gasket. The gasket is located near the cylinder. When the inner wall of the oil discharge port and the sealing block collide with the gasket, the sealing effect of the oil discharge port can be improved; the amount of oil that can be stored in the space from the oil discharge port to the bottom of the cylinder is less than the amount of oil that can be stored in the funnel, so that when there is no gap between the sealing block and the gasket, the oil can be discharged into the funnel through the oil filling pipe for suction filtration, and it also prevents too much oil from being poured into the funnel at one time, causing the oil to flow onto the measuring instrument; when the sealing block moves upward, the oil discharge port transports the fuel oil to the oil filling pipe, and when the oil flows into the funnel, it is temperature-controlled and heated by the temperature control plate; The oil is filtered through filter paper to remove mechanical impurities contained in it. Turn on the vacuum pump and perform vacuum filtration through the vacuum pump exhaust pipe. After the filtration, the filter paper is cleaned with solvent oil. Then turn off the vacuum pump, dry the filter paper to constant weight and weigh it. Enter the mass of the filter paper with mechanical impurities on the control screen. Perform a blank test and enter the mass according to the same steps. The measuring instrument can calculate and save the results. After the test, stop heating the funnel and clean the used detection tools. The cleaned small-volume tools can be stored in the pallet. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the filtering mechanism 2 includes a heating plate 201 and a suction bottle 202. The heating plate 201 is fixedly installed on the impurity measuring instrument body 1. The suction bottle 202 is installed on the heating plate 201. The suction bottle 202 is fixedly installed with a bent pipe 205. The impurity measuring instrument body 1 is fixedly installed with a vacuum pump suction pipe 206. The vacuum pump suction pipe 206 is connected to the bent pipe 205. The top of the suction bottle 202 is clamped with a rubber plug 204. The rubber plug 204 is clamped with a drain plug. The funnel 203 is connected to the interior of the suction filter bottle 202, the funnel 203 is connected to the temperature control plate 301, the oil filling pipe 505 is connected to the interior of the funnel 203, the heating mechanism 3 is installed inside the impurity measuring instrument body 1, and then the filter mechanism 2 is snapped into the heating mechanism 3, the fuel oil placed in the filter mechanism 2 can be temperature-controlled and heated, that is: the operator first snaps the two temperature control plates 301 into the two slots 304 provided at the top of the impurity measuring instrument body 1, because The temperature control plate 301 is arranged in an inclined structure. When the operator puts the funnel 203 into the temperature control plate 301, the funnel 203 can be in contact with the inner wall of the temperature control plate 301, and then the fuel oil detected in the funnel 203 can be heated by the temperature control plate 301 in the subsequent experimental process; then the rubber plug 204 is sleeved on the side wall of the funnel 203 from the bottom end, and then the rubber plug 204 is engaged with the suction bottle 202 placed on the heating plate 201, and the rubber plug 204 is pressed against the bottle mouth of the suction bottle 202. When touched, the interior of the suction bottle 202 can be sealed; a bent pipe 205 is installed on the suction bottle 202, and a vacuum pump is provided inside the impurity measuring instrument body 1. The vacuum pump exhaust pipe 206 is installed on the side wall of the impurity measuring instrument body 1 and is connected with the interior of the vacuum pump. The end of the vacuum pump exhaust pipe 206 facing away from the impurity measuring instrument body 1 is sleeved on the end of the bent pipe 205, so that the vacuum pump exhaust pipe 206 can be connected with the interior of the suction bottle 202 through the bent pipe 205, thereby facilitating the installation of the detection tool before detection.

[0033] Specifically, Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the main mechanism 6 includes a baffle 601 and a measuring cup 602, the baffle 601 and the control screen 603 are fixed on the impurity measuring instrument body 1, the measuring cup 602 is placed on the impurity measuring instrument body 1, the impurity measuring instrument body 1 is rotatably connected with a box door 604, the impurity measuring instrument body 1 is fixedly installed with two groups of mounting blocks 606, and the mounting blocks 606 are slidably connected with a clamping plate 605. The parameters of the experiment can be set through the main mechanism 6. During the detection, the feeding mechanism 5 is rotated to add the lubricating oil to the filtering mechanism 2, which reduces the operator's work steps of repeatedly pouring oil and prevents the oil from flowing onto the measuring instrument and being difficult to clean due to pouring too much oil at one time, that is: testing according to needs Fuel oil, turn on the switch of the impurity analyzer body 1, and set its test parameters or sample numbers through the control screen 603; during testing, the filter paper with constant weight can be put into the funnel 203 first. After the fuel oil is stored in the cylinder 504, the oil at the bottom of the cylinder 504 can be discharged into the interior of the funnel 203 through the oil filling pipe 505. When the oil filling pipe 505 does not discharge oil and the amount of oil in the funnel 203 decreases, the operator can rotate the rotating block 501 by hand. The rotating block 501 is fixedly connected to the screw rod 502. When the rotating block 501 drives the screw rod 502 to rotate, the screw rod 502 can be rotated along the inner wall of the cylinder cover 503.

The amount of oil that can be stored in the space from the oil discharge port 508 to the bottom of the cylinder 504 is less than the amount of oil that can be stored in the funnel 203. In this way, when there is no gap between the sealing block 506 and the gasket 507, the oil can be discharged into the funnel 203 through the oil filling pipe 505 for suction filtration. At the same time, it also prevents the oil poured into the funnel 203 at one time from flowing onto the measuring instrument due to too much oil. 6 When moving upward, the oil discharge port 508 delivers the fuel oil to the oil filling pipe 505. When the oil flows into the funnel 203, it is temperature-controlled and heated by the temperature control plate 301; the oil is filtered through the filter paper to remove mechanical impurities contained therein, and the vacuum pump is turned on to perform vacuum filtration through the vacuum pump exhaust pipe 206. After the filtration, the filter paper is cleaned with solvent oil, and then the vacuum pump is turned off. The filter paper is dried to a constant weight and weighed, and the mass of the filter paper with mechanical impurities is entered on the control screen 603. A blank test is then performed and the mass is entered according to the same steps. The measuring instrument can calculate and save the results. After the test, the heating of the funnel 203 is stopped and the used detection tools are cleaned; the small-volume tools after cleaning can be stored in the card board 605.

[0034] When the present invention is used, first, the operator inserts the two temperature control plates 301 into the two card slots 304 provided at the top of the impurity measuring instrument body 1. Since the temperature control plates 301 are arranged in an inclined structure, when the operator inserts the funnel 203 into the temperature control plates 301, the funnel 203 can be brought into contact with the inner wall of the temperature control plates 301, and then in the subsequent experimental process, the fuel oil detected in the funnel 203 can be temperature-controlled and heated by the temperature control plates 301; then, the rubber plug 204 is sleeved on the side wall of the funnel 203 from the bottom end thereof, and then the rubber plug 204 is brought into contact with the suction filter placed on the heating plate 201. The bottles 202 are snap-fitted and connected, and when the rubber plug 204 contacts the bottle mouth of the suction bottle 202, the interior of the suction bottle 202 can be sealed; a curved pipe 205 is installed on the suction bottle 202, and a vacuum pump is provided inside the impurity measuring instrument body 1, and a vacuum pump exhaust pipe 206 is installed on the side wall of the impurity measuring instrument body 1 and communicated with the interior of the vacuum pump. The end of the vacuum pump exhaust pipe 206 facing away from the impurity measuring instrument body 1 is sleeved on the end of the curved pipe 205, so that the vacuum pump exhaust pipe 206 can be communicated with the interior of the suction bottle 202 through the curved pipe 205, thereby facilitating the installation of the detection tool before detection;

[0035] Two groups of fixing rods 401 are fixed on the top of the impurity measuring instrument body 1, and the tops of several fixing rods 401 are fixedly connected to the supporting ring 402. The cylinder 504 is clamped into the mounting groove 7 provided in the supporting ring 402. When the bottom end of the cylinder 504 contacts the inner wall of the supporting ring 402, the cylinder 504 can be supported; after the fuel oil to be used for testing is placed inside the cylinder 504, the cylinder cover 503 is rotated to seal the top of the cylinder 504, so as to prevent dust or other impurities from easily entering the fuel oil when the top of the cylinder 504 is in an open state, and at the same time, it is convenient to store the fuel oil through the cylinder 504;

[0036] According to the fuel oil to be tested, turn on the switch of the impurity analyzer body 1, and set its test parameters or sample numbers through the control screen 603; during the test, the filter paper with constant weight can be put into the funnel 203 first. After the fuel oil is stored in the cylinder 504, the oil at the bottom of the cylinder 504 can be discharged into the interior of the funnel 203 through the oil filling pipe 505. When the oil filling pipe 505 does not discharge oil and the amount of oil in the funnel 203 decreases, the operator can rotate the rotating block 501 by hand. The rotating block 501 is fixedly connected to the screw rod 502. When the rotating block 5 01 When the screw rod 502 is driven to rotate, the screw rod 502 can rotate along the inner wall of the cylinder cover 503. The screw rod 502 and the cylinder cover 503 are threadedly connected, and a sealing block 506 is installed at the bottom end of the screw rod 502. When the screw rod 502 drives the sealing block 506 to move toward the cylinder cover 503, the sealing block 506 can be separated from the gasket 507. The gasket 507 is located on the inner wall of the cylinder 504 near the oil discharge port 508. When the sealing block 506 and the gasket 507 collide with each other, the sealing effect of the oil discharge port 508 can be improved; the oil discharge port 508 to The amount of oil that can be stored in this part of the space at the bottom of the cylinder 504 is less than the amount of oil that can be stored in the funnel 203. In this way, when there is no gap between the sealing block 506 and the gasket 507, the oil can be discharged into the funnel 203 through the oil filling pipe 505 for suction filtration. At the same time, it also prevents too much oil from being poured into the funnel 203 at one time, causing the oil to flow onto the measuring instrument. When the sealing block 506 moves upward, the oil discharge port 508 transports the fuel oil to the oil filling pipe 505. When the oil flows into the funnel 203, it is temperature-controlled and heated by the temperature control plate 301. The oil is filtered by the filter paper. Filter the mechanical impurities contained inside, turn on the vacuum pump, and perform vacuum filtration through the vacuum pump exhaust pipe 206. After the filtration, clean the filter paper with solvent oil, then turn off the vacuum pump, dry the filter paper to constant weight and weigh it, and enter the mass of the filter paper with mechanical impurities on the control screen 603. Then perform a blank test and enter the mass according to the same steps. The measuring instrument can calculate and save the results. After the test, stop heating the funnel 203 and clean the used detection tools; the small volume tools after cleaning can be stored in the card board 605.
