It can be used as a power source for aircraft, ships, etc. The nozzle in the gas engine is prone to clogging after being used for a period of time, which reduces the flow rate of the gas engine nozzle. At this time, it is necessary to use a gas engine nozzle flow test device to detect the flow rate of the gas engine nozzle to ensure that the gas engine nozzle can be used normally.

[0025] As a further implementation scheme of the above technical scheme: the interiors of the two sliders 11 are threadedly connected to the side surfaces of the bidirectional threaded rod 7, two limiting holes are provided inside the two sliders 11, and two limiting rods 16 are fixed inside the fixing seat 6. The sides of the two limiting rods 16 are respectively fitted with the insides of the four limiting holes, and the limiting rods 16 facilitate improving the stability of the slider 11 when moving.

[0026] As a further implementation scheme of the above technical scheme: one side of the two pressure plates 13 is provided with an anti-skid pad 17, and one side of the two anti-skid pads 17 is fixedly connected to one side of the two pressure plates 13 respectively, so that the anti-skid pad 17 can improve the limiting effect of the pressure plate 13 on the combustion engine body.

[0028] In specific implementation, when the engine body needs to be weighed, if the engine body is small in size, the engine body is directly placed on the first support plate 5 and the second support plate 12, and the engine body is weighed by the weighing device body 4. The weight indication of the engine body is observed through the display screen 14, the engine body is turned on to work and the timing is started. After working for a period of time, the engine body is turned off and the timing is stopped. The weight of the engine body at this time is measured again by the weighing device body 4. The difference between the two engine body weights is divided by the fuel density to measure the nozzle flow rate. When the engine body size is large, the fuel flow rate is measured again. When the width is large, the engine body is placed on the top of the two placement plates 15, and the forward and reverse motor 9 is started. The forward and reverse motor 9 rotates to drive the second gear 10 to rotate, thereby driving the first gear 8 to rotate, thereby driving the bidirectional threaded rod 7 to rotate, thereby driving the two sliders 11 to move away from each other, thereby driving the two pressure plates 13 to move away from each other, so that the distance between the two pressure plates 13 is greater than the width of the engine body. At this time, the hydraulic cylinder 2 is started to rise, thereby driving the fixed plate 3, the weighing equipment body 4, the first support plate 5 and the second support plate 12 to move up, so that the first support The plate 5 and the second support plate 12 are in contact with the lower part of the engine body. At this time, the forward and reverse motor 9 is started to reverse, thereby driving the second gear 10 to reverse, thereby driving the first gear 8 to reverse, thereby driving the two-way threaded rod 7 to reverse, thereby driving the two sliders 11 to approach each other, thereby driving the two pressure plates 13 to approach each other, so that the sides of the two pressure plates 13 are in contact with the engine body, and the engine body is limited by the pressure plate 13. The anti-skid pad 17 improves the limiting effect of the pressure plate 13 on the engine body. At this time, the hydraulic cylinder 2 drives the fixed plate 3, the weighing equipment body 4, The first support plate 5 and the second support plate 12 are moved upward, so that the bottom end of the fuel engine body is separated from the placement plate 15, and the fuel engine body can be weighed, so that the device can easily expand the overall width of the first support plate 5 and the second support plate 12, so that the weighing equipment body 4 can stably support the larger fuel engine body, and at the same time, the two pressure plates 13 can be used to clamp the fuel engine body, thereby further improving the stability of the fuel engine body when it is placed, making it difficult for the fuel engine body to slide on the weighing equipment body 4, thereby improving the safety and accuracy of the device when detecting the nozzle flow.

[0029] As a further implementation of the above technical solution: a sealing frame 18 is provided on one side of the placement table 1 , and one side of the sealing frame 18 is fixedly connected to one side of the placement table 1 , so that the sealing frame 18 is convenient for protecting the display screen 14 .

[0030] As a further implementation scheme of the above technical scheme: a sealing groove is provided inside the sealing frame 18 , and a connecting frame 19 is provided inside the sealing groove. The connecting frame 19 is convenient for improving the sealing performance of the connection between the glass plate 20 and the sealing frame 18 .

[0031] As a further implementation scheme of the above technical scheme: a connection groove is provided inside the connection frame 19 , and a glass plate 20 is fixed inside the connection groove. The glass plate 20 is convenient for protecting the display screen 14 .

[0032] As a further implementation of the above technical solution: a handle 21 is provided on one side of the connecting frame 19 , and one side of the handle 21 is fixedly connected to one side of the connecting frame 19 , so that the handle 21 facilitates the movement of the glass plate 20 .

[0033] During specific implementation: when the engine body is weighed by the weighing device body 4, it is necessary to observe the weighing indication through the display screen 14 in order to calculate the engine nozzle flow rate. The engine body is prone to dripping fuel in the process of moving to the top of the device. When too much fuel falls on the surface of the display screen 14, it is easy to make the display screen 14 blurred, affecting the viewing of the weighing indication, and it is easy to penetrate into the inside of the display screen 14, causing damage to the internal circuit board of the display screen 14, reducing the service life of the display screen 14, thereby reducing the detection efficiency of the engine nozzle flow rate of the device. When fuel drips, the sealing frame 18 and the glass plate 20 are used to protect the display screen 14 to prevent fuel from falling on the display screen 14. The connecting frame 19 is made of rubber, which is convenient for improving the sealing connection between the sealing frame 18 and the glass plate 20. The glass plate 20 is easy to clean and the clarity of the display screen 14 is not affected. The device can protect the display screen 14 from the adhesion of fuel to the surface of the display screen 14, thereby preventing the surface of the display screen 14 from being blurred or the internal circuit board of the display screen 14 from being damaged. The clarity and service life of the display screen 14 are improved, thereby improving the detection efficiency of the device for the nozzle flow of the combustion engine.
