Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pump casings, in particular to a hydraulic pump capable of rapidly dissipating heat. Background Art

[0002] The pump casing of a hydraulic pump is one of the main components of the pump. It is a closed space used to accommodate the moving parts and liquid inside the pump. The design and material of the pump casing have an important impact on the performance and life of the pump. In the hydraulic system, the pump casing must not only ensure the normal operation of the pump, but also take into account factors such as system efficiency, noise control, and ease of maintenance. Therefore, the design of the pump casing is a comprehensive project that needs to take into account cost-effectiveness and long-term reliability.

[0003] At present, hydraulic pumps will generate large vibrations during use. They are directly connected to some fixed objects through the pump casing, which cannot buffer the vibrations well. This not only affects the internal structure of the hydraulic pump itself and causes damage, but also reduces its service life. In addition, large vibrations may also cause the nuts and bolts used for fixing to loosen, leading to accidents. Long-term and high-intensity vibrations may cause the pump casing to rupture, affecting the normal use of the hydraulic pump.

[0004] To this end, we provide a hydraulic pump that can quickly dissipate heat to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a hydraulic pump capable of rapidly dissipating heat, and through a buffer component, the vibration generated by the hydraulic pump is buffered to solve the existing problem of large vibration.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a hydraulic pump capable of rapid heat dissipation, comprising a fixing component, including a base, and a bracket arranged inside the base, wherein the bracket is slidably connected inside the base;

[0008] A buffer component, comprising a connecting assembly disposed inside the base, a piston assembly disposed inside the connecting assembly, and a base assembly disposed at the bottom of the piston assembly;

[0009] The connecting assembly includes a receiving groove opened inside the base, a fixing cylinder arranged inside the receiving groove, an oil storage cylinder opened inside the fixing cylinder, a telescopic cylinder sleeved outside the fixing cylinder, and a connecting rod arranged inside the telescopic cylinder.

[0010] The utility model is further configured such that the piston assembly includes a limiting rod arranged at the bottom of the connecting rod, a return spring arranged outside the limiting rod, a piston body arranged on the other side of the return spring, a first channel opened on the piston body, a second channel opened on the piston body, a limiting plate arranged on the top of the piston body, a flow channel opened on the surface of the limiting plate, and a first spring sheet arranged at the bottom of the piston body.

[0011] The utility model is further configured such that the base assembly includes a resistance rod arranged at the bottom of the oil storage cylinder, a tension spring arranged outside the resistance rod, a base body arranged on the other side of the tension spring, a first through hole opened on the base body, a second through hole opened on the base body, a resistance plate arranged on the top of the base body, a flow through hole opened on the surface of the resistance plate, and a second spring sheet arranged at the bottom of the base body.

[0012] The utility model is further configured to further include a heat dissipation component, including a heat dissipation component arranged on the top of the bracket, and a water cooling component arranged inside the heat dissipation component.

[0013] The utility model is further configured such that the heat dissipation assembly includes an outer shell body arranged on the top of the bracket, a protective cover arranged on one side of the outer shell body, a negative pressure fan arranged inside the outer shell body, and a protective net arranged inside the outer shell body corresponding to the outside of the negative pressure fan.

[0014] The utility model is further configured such that the water cooling component includes an inner shell body arranged inside the outer shell body, heat-conducting fins arranged on the outer wall of the inner shell body, a spiral pipe arranged inside the inner shell body, a spiral water pipe arranged inside the spiral pipe, a connecting pipe arranged at the end of the spiral water pipe, a circulating water pump arranged at the end of the connecting pipe, a cooling water tank arranged at the water outlet end of the circulating water pump, and a guide pipe arranged at one end of the cooling water tank.

[0015] The utility model is further configured that a rotating cover is provided at the top end of the cooling water tank, and the heat conducting fins are located at the rear side of the protective net.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model uses the buffer component to squeeze the hydraulic oil inside the fixed cylinder into the oil storage cylinder. The volume of the oil storage cylinder remains unchanged, while the nitrogen filled inside is compressed and its pressure increases, which prevents the hydraulic oil from continuing to enter the oil storage cylinder, thereby preventing the piston body from continuing to fall, thereby playing a buffering role and preventing the pump housing from vibrating too much and avoiding damage to the machine.

[0018] 2. The utility model initially cools down the pump casing by the cooperation of the negative pressure fan and the heat-conducting fins. In addition, a spiral water pipe is arranged inside the inner casing to circulate the coolant to continuously cool down the pump casing. The two cooling methods cooperate with each other to rapidly reduce the temperature of the pump casing.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0030] See also Figure 1-3 , the utility model is a fixing component 100, comprising a base 101, and a bracket 102 disposed inside the base 101, wherein the bracket 102 is slidably connected inside the base 101;

[0031] The buffer component 200 includes a connecting component 201 disposed inside the base 101 , a piston component 202 disposed inside the connecting component 201 , and a base component 203 disposed at the bottom of the piston component 202 .

[0032] Specifically, the connecting assembly 201 includes a receiving groove 201a opened inside the base 101, a fixed cylinder 201b arranged inside the receiving groove 201a, an oil storage cylinder 201c opened inside the fixed cylinder 201b, a telescopic cylinder 201d sleeved on the outside of the fixed cylinder 201b, and a connecting rod 201e arranged inside the telescopic cylinder 201d.

[0033] The operation process of this embodiment is as follows: first, a proper amount of hydraulic oil is filled into the interior of the fixed cylinder 201b, and then a certain amount of nitrogen is filled into the interior of the oil storage cylinder 201c, but it is not completely filled. A portion of the hydraulic oil is filled into the interior of the oil storage cylinder 201c, and a certain amount of hydraulic oil is always maintained in the interior of the oil storage cylinder 201c, so that the fixed cylinder 201b and the oil storage cylinder 201c are connected to each other. Specific embodiment 2

[0035] See also Figure 1-3 On the basis of the specific embodiment one, the piston assembly 202 includes a limiting rod 202a arranged at the bottom of the connecting rod 201e, a return spring 202b arranged outside the limiting rod 202a, a piston body 202c arranged on the other side of the return spring 202b, a first channel 202d opened on the piston body 202c, a second channel 202e opened on the piston body 202c, a limiting plate 202f arranged on the top of the piston body 202c, a flow channel 202g opened on the surface of the limiting plate 202f, and a first spring sheet 202h arranged at the bottom of the piston body 202c.

[0036] Specifically, the base assembly 203 includes a resistance rod 203a arranged at the bottom of the oil storage cylinder 201c, a tension spring 203b arranged outside the resistance rod 203a, a base body 203c arranged on the other side of the tension spring 203b, a first through hole 203d opened on the base body 203c, a second through hole 203e opened on the base body 203c, a resistance plate 203f arranged on the top of the base body 203c, a flow through hole 203g opened on the surface of the resistance plate 203f, and a second spring sheet 203h arranged at the bottom of the base body 203c.

[0037] The operation process of this embodiment is as follows: first, the pump housing vibrates, and the piston body 202c moves downward. At this time, under the action of atmospheric pressure, the first spring leaf 202h will be deformed downward, and the limiting plate 202f will also be close to the piston body 202c, so that the first channel 202d is opened. At this time, the hydraulic oil on the upper part of the piston body 202c will enter the working cylinder, and the piston body 202c continues to move downward. The volume in the working cylinder changes, and its atmospheric pressure increases. The hydraulic oil flows out from the second through hole 203e. Under the action of atmospheric pressure, the second spring leaf 203h is deformed downward. At this time, the hydraulic oil enters the oil storage cylinder 201c, and the nitrogen inside it is compressed. When the piston body 202c is released, the nitrogen can expand rapidly and enter the oil storage cylinder 201c. The hydraulic oil will flow back, and the expansion of nitrogen will force the hydraulic oil to lift the baffle plate 203f, which is equivalent to the first through hole 203d being opened, and the hydraulic oil enters the working cylinder. Then the hydraulic oil continues to move upward, and will lift the limiting plate 202f upward and enter the space above the piston body 202c, so as to balance the pressure one by one, thereby achieving the purpose of buffering the pump casing of the hydraulic pump and reducing the vibration generated by the hydraulic pump. The second channel 202e, the limiting plate 202f, the second through hole 203e and the baffle plate 203f are used to control the fluidity of the hydraulic oil to achieve the purpose of limiting the flow of the hydraulic oil, so that the movement amplitude of the piston body 202c is greatly reduced, so that the buffering effect of the entire buffer assembly is better, and the pump casing can be better buffered to prevent the pump casing from cracking. Specific embodiment three

[0040] Specifically, the heat dissipation assembly 301 includes an outer shell 301a arranged on the top of the bracket 102, a protective cover 301b arranged on one side of the outer shell 301a, a negative pressure fan 301c arranged inside the outer shell 301a, and a protective net 301d arranged inside the outer shell 301a corresponding to the outside of the negative pressure fan 301c.

[0042] The operation process of this embodiment is as follows: first, the coolant is cooled inside the cooling water tank 302g, and then, under the action of the circulating water pump 302f, the coolant is pumped into the inside of the spiral water pipe 302c to cool the pump casing, wherein the spiral water pipe 302c is arranged in a spiral shape to ensure that the coolant can stay inside the pump casing for a long enough time to ensure the cooling effect, and then the coolant flows out from the connecting pipe 302e on the other side, passes through the circulating water pump 302f and returns to the inside of the cooling water tank 302g for recycling, and in addition, a heat-conducting fin 302b is arranged on the outside of the inner casing 302a to cool the outside of the heat-conducting fin 302b, and a negative pressure fan 301c is arranged on one side of the heat-conducting fin 302b to accelerate the air flow rate between the two heat-conducting fins 302b, so that the cooling effect is better, and the two cooling methods cooperate with each other to enable the temperature of the pump casing to be rapidly reduced, thereby ensuring the normal operation of the hydraulic pump and preventing failure due to excessive temperature.
