DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 , the utility model provides an embodiment: a pneumatic fuel pump skid installation structure, including a skid base 1;

[0023] A limit plate 10 is installed at the bottom end of the skid base 1 on the side opposite to the oil pump 4, and the cross section of the limit plate 10 is an inverted right-angled trapezoid, and the inclined surface of the limit plate 10 abuts against the outer edge of the base 9;

[0024] Specifically, such as Figure 1 、 Figure 2 As shown, the structure of the limiting plate 10 is used to limit the installation position of the front end of the base 9 during use, and the special structure of the limiting plate 10 is used to intercept the top of the base 9 to synchronously limit the top of the base 9, thereby preventing the base 9 and the skid base 1 from vibrating upward and downward;

[0025] Filters 2 are installed on both sides of the skid base 1, and the oil inlet ends of the two filters 2 are connected to the first three-way pipe 3. Bases 9 are installed on both sides of the skid base 1;

[0026] A chamfered edge 15 is formed at the bottom end of the base 9 on the side away from the limit plate 10, and a handle 16 is installed on the top end of the base 9 on the side opposite to the chamfered edge 15. Balls 14 are evenly embedded on the side of the bottom end of the skid base 1 away from the limit plate 10, and the balls 14 are evenly spaced laterally and parallel to the chamfered edge 15.

[0027] The bottom end of the base 9 is evenly provided with grooves 17, and the top of the grooves 17 is installed with magnetic blocks 18, and the bottom end of the magnetic blocks 18 is installed with buffer pads 23, and the bottom end of the buffer pads 23 is against the bottom end of the inside of the skid base 1;

[0028] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, when in use, the magnetism of the magnetic block 18 is utilized to cause it to produce adsorption to the skid base 1, thereby enhancing the connection strength between the base 9 and the skid base 1. At the same time, the ball 14 is utilized to push the base 9 when it moves outward, thereby reducing the difficulty of disassembly between the base 9 and the skid base 1.

[0029] The two bases 9 are respectively located on the two outer sides of the filter 2, and an oil pump 4 is installed on one side of the top of the base 9 near the filter 2. A driving motor 5 is installed on the other side of the top of the base 9, and the output end of the driving motor 5 is connected to the rotating shaft end of the oil pump 4 through a coupling 6. The oil outlet end of the filter 2 is connected to the oil inlet end of the oil pump 4 through an oil suction pipe 22. The oil outlet end of the oil pump 4 is installed with an oil outlet pipe 7, and the opposite ends of the two oil outlet pipes 7 are connected with a second three-way pipe 8. The oil outlet pipe 7, the second three-way pipe 8 and the coupling 6 form a rectangular surrounding structure. The outside of the oil outlet pipe 7 is installed with a supporting sleeve rod 21, and the bottom end of the supporting sleeve rod 21 is connected to the bottom end of the inside of the skid base 1. Connecting plates 12 are installed on both sides of the base 9 near the drive motor 5, and positioning bolts 13 are passed through the inside of the connecting plate 12. At the same time, the bottom end of the positioning bolt 13 extends to the inside of the skid base 1, and side fixing components 11 are provided on both sides of the base 9 near the oil pump 4;

[0030] The side fixing assembly 11 includes an L-shaped side guide plate 1101 mounted on the bottom end of the skid base 1. The L-shaped side guide plate 1101 is located outside the base 9. A connecting groove 1102 is formed at the top end of the L-shaped side guide plate 1101. A connecting block 1103 is mounted on the top end of the base 9 near the outer edge of the connecting groove 1102. The position of the connecting block 1103 corresponds to the upper and lower sides of the connecting groove 1102.

[0031] A hollow silicone pad 19 is installed on the top of the connecting block 1103 , and the interior of the hollow silicone pad 19 is filled with a non-Newtonian fluid 20 . The top of the hollow silicone pad 19 abuts against the inner wall of the connecting groove 1102 .

[0032] The cross-section of the connecting block 1103 and the connecting groove 1102 is a wave-shaped structure. Two L-shaped side guide plates 1101 are provided, and the distance between the two L-shaped side guide plates 1101 is adapted to the width of the base 9.

[0033] Specifically, such as Figure 1 、 Figure 2and Figure 3 As shown, during use, the fluidity of the non-Newtonian fluid 20 is utilized to improve the tightness of the connection between the connecting block 1103 and the connecting groove 1102, and the non-deformability of the non-Newtonian fluid 20 under sudden force is utilized to enhance the connection stability between the oil pump 4, the drive motor 5 and the skid base 1, thereby reducing the shaking of the oil pump 4 and the drive motor 5.

[0034] Working principle: When the utility model is in use, the drive motor 5 is first started to start the oil pump 4 and generate negative pressure suction on the oil extraction pipe 22, and the fuel is transported to the two filters 2 through the first three-way pipe 3. The oil pump 4 is used to transfer the filtered fuel to the oil extraction pipe 22, and then the oil outlet pipe 7 and the second three-way pipe 8 are used to continuously transfer the fuel to the rear-end equipment. By using the cooperation of the first three-way pipe 3 and the second three-way pipe 8, when the filter 2 or the oil pump 4 on one side is damaged, the same structure on the other side can be used to ensure the normal operation of the fuel.

[0035] Secondly, when the base 9 needs to be disassembled, the positioning bolts 13 on both sides can be removed, and the base 9 can be slowly pulled backward using the handle 16 to make the base 9 move backward along the L-shaped side guide plate 1101, so that the connecting block 1103 is separated from the connecting groove 1102. As the base 9 continues to move backward, the chamfered edge 15 contacts the ball 14, and under the action of the ball 14, the rear end of the base 9 is lifted upward, thereby facilitating the separation of the bottom end of the base 9 from the bottom end inside the skid base 1, thereby realizing the disassembly of the base 9;

[0036] Finally, the fluidity of the non-Newtonian fluid 20 in the silicone hollow pad 19 is utilized to make the connecting block 1103 fully contact with the connecting groove 1102. At the same time, when the oil pump 4 and the drive motor 5 are running, the characteristics of the non-Newtonian fluid 20 are utilized to make the non-Newtonian fluid 20 less likely to deform under sudden stress, thereby enhancing the contact tightness between the connecting block 1103 and the connecting groove 1102, thereby enhancing the connection strength between the base 9 and the L-shaped side guide plate 1101, and thereby increasing the overall connection weight of the oil pump 4 and the drive motor 5, thereby reducing the vibration amplitude of the oil pump 4 and the drive motor 5 and reducing its shaking.
