Description

Technical Field

[0001] The utility model relates to the technical field of fuel tanks, and particularly relates to a pressurized fuel tank. Background Art

[0002] In a hydraulic system, as a key component for storing and supplying oil fluid, the performance of the fuel tank directly affects the operation efficiency and stability of the entire system. With the continuous development of industrial technology, the requirements for the performance of hydraulic systems are also increasing day by day. Especially under high pressure, large flow rate and complex working conditions, the pressurization ability of the fuel tank has become one of the important indicators for measuring its performance. Traditional pressurized fuel tanks mainly include three types: gas pressurized type, self-increasing pressurized type and spring pressurized type;

[0003] The spring pressurized fuel tank cleverly uses the elastic potential energy of the spring as the pressurization power source, and promotes the flow of oil fluid through the compression and release of the spring to achieve the pressurization effect. This method has the advantages of reliable pressurization and little influence by temperature, so it has been widely used in many fields. However, the spring pressurized fuel tank also has certain defects. Since the displacement of the spring is difficult to directly monitor, the fuel tank cannot send out an alarm signal in time when the liquid level is low, increasing the risk of system damage due to insufficient oil fluid.

[0004] Therefore, a pressurized fuel tank is needed to overcome the occurrence of the above problems. Content of the Utility Model

[0005] In order to solve the above problems, the embodiment of the utility model provides a pressurized fuel tank, achieving the purpose of solving the problems proposed in the background art.

[0006] The embodiment of the utility model specifically adopts the following technical solution to achieve the above purpose: a pressurized fuel tank, including a fuel tank main body, a piston is slidably arranged inside the fuel tank main body, one end of the fuel tank main body is fixedly connected with a fuel tank end cover, and a first spring abutting against one side of the piston is arranged inside the fuel tank end cover; one end of the piston is fixedly connected with a support rod, and a travel switch cooperating with the support rod is arranged inside the fuel tank end cover; the support rod is composed of a high liquid level part and a low liquid level part with different diameters.

[0007] As a further improvement of the above technical solution:

[0008] A display component for displaying the liquid level inside the fuel tank main body is threadedly connected inside the fuel tank end cover.

[0009] The display component includes a plug threadedly connected to one end of the fuel tank end cover, and a display rod elastically slidably arranged inside the plug through a second spring; the display rod abuts against one end of the support rod.

[0010] The fuel tank end cover is fixedly connected to one end of the fuel tank body by bolts.

[0011] A support ring is provided on the side wall of the piston.

[0012] A plug is fixedly connected to the fuel tank end cover.

[0013] The beneficial effects of the embodiments of the present utility model are as follows:

[0014] During actual use, when the fuel tank body is filled with oil, the piston is in the rightmost position under the push of the hydraulic pressure. At this time, when the elastic piece abuts against the high liquid level part, the travel switch is in a power-off state. As the oil in the fuel tank body decreases, the support rod moves to the left. When the elastic piece abuts against the low liquid level part, the travel switch is powered on, thereby sending out a low liquid level alarm signal; that is, the low liquid level monitoring inside the fuel tank body is realized through the cooperation of the travel switch and the support rod.

[0023] The support rod 5 is composed of a high liquid level part 51 and a low liquid level part 52 with different diameters; a spring piece is arranged on the travel switch 6 and abuts against the support rod 5. When the spring piece abuts against the high liquid level part 51, the travel switch 6 is in a power-off state. When the spring piece abuts against the low liquid level part 52, the travel switch 6 is powered on, thereby sending out a low liquid level alarm signal;

[0024] During actual use, when the fuel tank main body 1 is filled with oil, the piston 2 is in the Figure 2 rightmost position, at this time, when the spring piece abuts against the high liquid level part 51, the travel switch 6 is in a power-off state. As the oil in the fuel tank main body 1 decreases, the support rod 5 moves to the left. When the spring piece abuts against the low liquid level part 52, the travel switch 6 is powered on, thereby sending out a low liquid level alarm signal; that is, the low liquid level in the fuel tank main body 1 is monitored through the cooperation of the travel switch 6 and the support rod 5.
