Description

Technical Field

[0001] This utility model relates to the field of automation control, and in particular to a constant pressure energy-saving hydraulic station with automatic flow regulation. Background Technology

[0002] A hydraulic power unit is a power source device that converts mechanical energy into hydraulic energy. It achieves efficient energy conversion and control through fluid transmission and is an indispensable power core in modern mechanical systems.

[0003] Currently, existing hydraulic power units often use PLC signals to control the cylinder to stop at any position, adjust the output pressure with a pressure regulating valve, adjust the speed with a throttle valve, and detect and feed back the outlet digital pressure to the PLC signal, which can achieve precise pressure regulation, flow control and operation.

[0004] While existing pressure detection and PLC signal control can accurately regulate pressure and flow, the viscosity of hydraulic oil decreases exponentially as the oil temperature rises. When the oil temperature exceeds 60°C, the pressure fluctuation range of the relief valve increases from ±0.5 bar to ±1.2 bar, directly leading to increased flow control error. Therefore, a constant pressure energy-saving hydraulic station with automatic flow regulation is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a constant pressure energy-saving hydraulic station with automatic flow regulation, which aims to improve the problem in the prior art that when the temperature is too high, the hydraulic oil viscosity decreases, resulting in a large flow control error.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a constant pressure energy-saving hydraulic station with automatic flow regulation, comprising a hydraulic station body, a temperature control mechanism disposed on the outside of the hydraulic station body, the temperature control mechanism comprising a mounting shell, the inner side of the mounting shell being fixedly connected to the outer wall of the hydraulic station body, a fan being fixedly connected to the inner wall of the mounting shell, a cooling pipe being fixedly connected to the outer wall of the hydraulic station body, a water pump being fixedly connected to the inner wall of the mounting shell, a temperature control component disposed inside the mounting shell, the temperature control component comprising a pneumatic pipe, the outer wall of the pneumatic pipe being fixedly connected to the inner wall of the mounting shell, a sliding plate being piston-connected to the inner wall of the pneumatic pipe, a control block being fixedly connected to the top of the sliding plate, and a mounting block being fixedly connected to the inner wall of the mounting shell located to the upper right of the pneumatic pipe.

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

[0008] The mounting block is internally provided with a starting component, which includes a mounting groove. The mounting groove is located at the left end of the mounting block. A slider is slidably connected to the inner wall of the mounting groove. A push block is fixedly connected to the left end of the slider, and a pressing strip is fixedly connected to the right end of the slider. The inner wall of the mounting groove and the right end of the slider are elastically connected by a spring.

[0009] As a further description of the above technical solution:

[0010] A heat-conducting strip is fixedly connected to the inner wall of the pneumatic pipe, and the end of the heat-conducting strip away from the pneumatic pipe is fixedly connected to the outer wall of the hydraulic station body.

[0011] As a further description of the above technical solution:

[0012] The cooling pipe is composed of multiple concave tubular structures arranged in a linear array in the vertical direction.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the mounting housing is provided with ventilation slots that communicate with the outside, and the ventilation slots are located on the left and right sides of the mounting housing.

[0015] As a further description of the above technical solution:

[0016] The water pump is fixedly connected to both ends of the cooling pipe.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up air pressure pipes, sliding plates, control blocks, mounting blocks, heat-conducting strips, sliders, pushing blocks, pressing strips, etc., it is ensured that when the hydraulic station body is raised, heat can be transferred to the air pressure pipes through the heat-conducting strips and start the fan. When the temperature is higher, the fan and water pump are started at the same time, so that the water body is driven by the water pump to circulate and move at different positions outside the hydraulic station body, and is cooled by the action of the fan, so as to ensure that the hydraulic oil temperature is suitable and will not affect the flow control effect.

[0023] 2. In this utility model, by setting the relative positions of the fan and the cooling pipe, it is ensured that the cooling pipe can enter the cooling area cooled by the fan after circulating for a shorter path, thereby ensuring that the coolant in the cooling pipe can absorb and release heat multiple times during the circulation process, thus achieving a better cooling effect on the hydraulic station and its internal hydraulic oil.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a constant pressure energy-saving hydraulic station with automatic flow regulation, comprising a hydraulic station body 1, an external temperature control mechanism 2 for cooling the hydraulic station body 1, and a mounting shell 21. The mounting shell 21 is concave in shape, and its inner wall has ventilation slots 27 communicating with the outside for heat dissipation. The ventilation slots 27 are located on the left and right sides of the mounting shell 21. The inner side of the mounting shell 21 is fixedly connected to the outer wall of the hydraulic station body 1, and a fan 22 is fixedly connected to the inner wall of the mounting shell 21. 2 is located at the rear end of the hydraulic station body 1. A cooling pipe 23 is fixedly connected to the outer wall of the hydraulic station body 1, and the inner side of the cooling pipe 23 is tightly fitted to the outer wall of the hydraulic station body 1. By fitting tightly, the temperature in the oil tank of the hydraulic station body 1 can be better transferred to the cooling pipe 23, thereby ensuring its cooling effect. The cooling pipe 23 is composed of multiple concave tubular objects arranged in a linear array in the vertical direction. A water pump 24 is fixedly connected to the inner wall of the mounting shell 21. The water pump 24 is fixedly connected to both ends of the cooling pipe 23. The cooling pipe 23 and the water pump 24 together form a closed end-connected pipeline.

[0033] Reference Figure 2 - Figure 4 The mounting housing 21 houses a temperature control component 25, which includes a pressure pipe 251. The outer wall of the pressure pipe 251 is fixedly connected to the inner wall of the mounting housing 21. The pressure pipe 251 is made of glass, ensuring it is not easily deformed by temperature. A heat-conducting strip 255 is connected through and fixedly to the inner wall of the pressure pipe 251. The pressure pipe 251 contains a gas that expands easily when heated. The heat-conducting strip 255 is made of copper, ensuring it has... With good thermal conductivity, the end of the heat-conducting strip 255 away from the air pressure pipe 251 is fixedly connected to the outer wall of the hydraulic station body 1. The inner wall of the air pressure pipe 251 is piston-connected to a sliding plate 252. The outer wall of the sliding plate 252 is in contact with the inner wall of the air pressure pipe 251, and the sliding plate 252 can move up and down while maintaining contact with the inner wall of the air pressure pipe 251. The top of the sliding plate 252 is fixedly connected to a control block 253, which is rectangular in shape. The mounting shell 21 is located on the inner wall of the upper right side of the air pressure pipe 251 and is fixedly connected to a mounting block 254.

[0034] Reference Figure 3 - Figure 5The mounting block 254 contains a starting component 26, which includes a mounting slot 261 located at the left end of the mounting block 254. Two sets of starting components 26 are arranged in a vertical linear array. A switch for a water pump 24 is located on the inner wall of the mounting slot 261 of the upper starting component 26. Pressing the switch activates the water pump 24. A switch for a fan 22 is located on the inner wall of the mounting slot 261 of the lower starting component 26. Pressing the switch activates the fan 22. When the fan 22 is started, a slider 262 is slidably connected to the inner wall of the mounting slot 261. The slider 262 slides left and right. A push block 263 is fixedly connected to the left end of the slider 262, and a pressing strip 264 is fixedly connected to the right end of the slider 262. The lower left corner of the pressing strip 264 is provided with an inclined chamfer. The inner wall of the mounting slot 261 and the right end of the slider 262 are elastically connected by a spring 265. One end of the spring 265 is fixedly connected to the inner wall of the mounting slot 261, and the other end of the spring 265 is fixedly connected to the right end of the slider 262.

[0035] Working principle: When the hydraulic station body 1 is in use, its temperature is high, and the temperature is transferred to the interior of the air pressure pipe 251 through the heat conduction strip 255. Since the air pressure pipe 251 and the hydraulic station body 1 are in the same environment, and the working workpiece is set above the hydraulic station body 1, the temperature of the hydraulic station body 1 is often higher than the ambient temperature of the air pressure pipe 251. Therefore, the influence of the environment on the higher temperature of the air pressure pipe 251 can be ignored.

[0036] When the gas inside the air pressure pipe 251 expands due to the heat transferred from the heat conduction strip 255, the slide plate 252 moves upward under the action of air pressure, and pushes the mounting block 254 upward during the movement.

[0037] When the mounting block 254 moves to contact the inclined surface of the lower push block 263, it applies an upward force to the push block 263 through its inclined surface. Since the push block 263 cannot move up and down, but can only move left and right, the push block 263 moves to the right after being subjected to the force, and drives the slider 262 and the pressing bar 264 to move to the right together, thereby pressing the switch of the fan 22.

[0038] If the control block 253 presses only the bottom push block 263 at this time, only the fan 22 will be in the start state, so the fan 22 will dissipate heat from the hydraulic station body 1 by means of airflow.

[0039] If the control block 253 continues to move upward and pushes the upper push block 263, then not only the switch of the fan 22 will be squeezed, but the switch of the water pump 24 will also be squeezed.

[0040] When the water pump 24 is turned on, the water circulates in the cooling pipe 23 under the action of the water pump 24's suction and discharge. Since the fan 22 is located behind the hydraulic station body 1, the water is cooled by the air force of the fan 22 when it flows to the rear end of the hydraulic station body 1. Since the cooling pipe 23 is at different heights and the water flows in opposite directions in the two connected sections, the water in one section has just been cooled, while the water in the other section is about to move to the cooling area. Therefore, the cooling pipe 23 with better cooling effect and the cooling pipe 23 with poorer cooling effect alternately contact the outer wall of the hydraulic station body 1, thus ensuring a better overall cooling effect.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
