Description

TECHNICAL FIELD

[0001] The utility model relates to the field of product testing and verification related equipment, in particular to a four valve six oil circuit hydraulic station with electrical control cabinet. BACKGROUND

[0002] In modern industrial production, as experimental equipment, the performance and application range of the hydraulic station are directly related to the integrity and verification efficiency of product verification. Especially for multiple oil circuits and multiple oil circuit cooperative work, higher requirements are put forward for the applicability of the hydraulic station.

[0003] Specifically, some old hydraulic stations perform poorly in implementing multiple oil circuits and oil circuit cooperative work, cannot solve the mutual cooperation problem between multiple oil circuits using simple valve group combinations, and the valve groups added to realize multiple oil circuits not only increase the cost of the hydraulic station, but also increase the volume of the hydraulic station. The lower integration undoubtedly reduces the operability and brings inconvenience to product testing and verification.

[0026] The preferred embodiments of the utility model are described in detail below in combination with the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.

[0027] In the embodiment, it is understood that the terms "upper surface", "one side" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model, and do not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] Please refer to Figure 1 As shown in the drawings, the embodiment of the application provides a four-valve six-oil-way hydraulic station with an electrical control cabinet, which comprises: an oil tank 1, a motor 2, a constant displacement gear pump 3, a liquid level meter 6, a forced air cooler 7, an oil return filter 9, an upright pressure gauge 10, an oil block one 12, a three-position four-way electromagnetic valve one 131, a three-position four-way electromagnetic valve two 132, a two-position three-way electromagnetic valve one 141, a two-position three-way electromagnetic valve two 142, a pressure reducing valve 15, an electrical cabinet 19, a universal wheel 21, and a directional wheel 22.

[0029] Please refer to Figure 2 As shown in the drawings, the electrical cabinet 19 specifically comprises: a power indicator light 191, an operation indicator light 192, an operating power knob 193, an oil pressure start button 194, an oil pressure stop button 195, a control knob 196 of the three-position four-way electromagnetic valve one, a control knob 197 of the three-position four-way electromagnetic valve two, a control knob 198 of the two-position three-way electromagnetic valve one, and a control knob 199 of the two-position three-way electromagnetic valve two.

[0030] The working principle of the hydraulic station with four valves, six oil circuits, and an electrical control cabinet provided in the above embodiment is as follows:

[0031] Please see Figure 3 As shown, motor 2 and fixed-displacement gear pump 3 start, supplying oil through check valve 8 and oil circuit block 12 to three-position four-way solenoid valve 131; the oil pressure can be observed through vertical pressure gauge 10 and adjusted through pressure reducing valve 15. Optionally, an oil supply filter 4 is also provided at the front end of motor 2. Optionally, oil is injected into oil tank 1 through oil injector 5, and the liquid level is observed through level gauge 6. Optionally, a pressure buffer 11 may be provided at the front end of vertical pressure gauge 10.

[0032] Please see Figure 5 As shown, the oil source enters through the oil inlet P. When electromagnets S1 and S2 are de-energized, oil circuits A1 and A2 are simultaneously energized. When electromagnet S1 is energized, oil circuit A2 is energized, while oil circuit A1 is de-energized. When electromagnet S2 is energized, oil circuit A1 is energized, while oil circuit A2 is de-energized. The oil pressure can be observed via the vertical pressure gauge 10 and adjusted via the pressure reducing valve 15.

[0033] Please see Figure 5 As shown, the oil source enters from the oil inlet P. When the two-position three-way solenoid valve 141 is not energized, oil circuit 5B1 is not energized. When the solenoid 3S3 is energized, oil circuit 5B1 is energized. When the system pressure exceeds the set value, the overflow valve 16 opens, allowing excess hydraulic oil to return to the oil tank 1 through the forced air cooler 7 and the return oil filter 9.

[0034] It should be understood that the three-position four-way solenoid valve 2132 and the three-position four-way solenoid valve 1131 have the same functional principle, and the two-position three-way solenoid valve 2142 and the two-position three-way solenoid valve 1141 have the same functional principle.

[0035] The operation method of the hydraulic station with four valves, six oil circuits, and an electrical control cabinet provided in the above embodiment is as follows:

[0036] First, operate the power control knob 193 on the oil tank of the electrical control cabinet to start the hydraulic station. Next, operate the hydraulic start button 194 on the control panel to start the hydraulic system. This two-step start enhances safety during operation. While observing the vertical pressure gauge 10, adjust the pressure reducing valve 15 to bring the output pressure to the required value. Figure 2When the three-position four-way electromagnetic valve one 131 is opened, the control knob 196 of the three-position four-way electromagnetic valve one is operated to the middle position, and the electromagnet one S1 and the electromagnet two S2 on both sides of the three-position four-way electromagnetic valve one 131 are not powered, and the oil path one A1 and the oil path two A2 are simultaneously supplied with oil. The control knob 196 of the three-position four-way electromagnetic valve one is rotated to the left or right position to realize the reversing input oil pressure.

[0037] It should be understood that the control knob 197 of the three-position four-way electromagnetic valve two is operated in the same way as the control knob 196 of the three-position four-way electromagnetic valve one.

[0038] Among them Figure 2 The two-position three-way electromagnetic valve one 141 is opened at the same time, and the control knob 198 of the two-position three-way electromagnetic valve one is operated, and the two-position three-way electromagnetic valve one 141 realizes oil supply and no oil supply. For example, as shown in Figure 3 , when the two-position three-way electromagnetic valve one 141 is powered to supply oil, it is output through the oil path five B1; when the two-position three-way electromagnetic valve one 141 loses power and does not supply oil, it is returned to the oil tank 1 through the oil block two 23.

[0039] It should be understood that the control knob 199 of the two-position three-way electromagnetic valve two is operated in the same way as the control knob 198 of the two-position three-way electromagnetic valve one.

[0040] In summary, the four-valve six-oil-way hydraulic station with an electrical control cabinet according to the embodiment of the application comprises: an oil tank 1 (i.e. a movable oil tank) with two universal wheels 21, four electromagnetic valves (i.e. a three-position four-way electromagnetic valve one 131, a three-position four-way electromagnetic valve two 132, a two-position three-way electromagnetic valve one 141, and a two-position three-way electromagnetic valve two 142), a forced air cooler 7, an electrical cabinet 19, a control panel (i.e. a panel comprising the above-mentioned indicator lights, knobs, and buttons), a motor 2, and a constant displacement gear pump 3. Two valves are three-position four-way electromagnetic valves, which are used to provide four oil paths and can realize reversing output; the other two valves are two-position three-way electromagnetic valves, which are used to provide one-way oil pressure output; each electromagnetic valve group is equipped with a pressure reducing valve 15 for pressure regulation and an upright pressure gauge 10.

[0041] The four-valve six-oil-way hydraulic station with an electrical control cabinet described above realizes the output state of the four-valve six-oil-way through the control panel by two three-position four-way electromagnetic valves and two two-position three-way electromagnetic valves. The two types of electromagnetic valves cooperate with each other to realize specific action requirements or time sequence requirements of different oil paths. Moreover, each electromagnetic valve group can be regulated by the pressure reducing valve 15 and the upright pressure gauge 10 to display the pressure value in real time. In addition, the system is equipped with a forced air cooler 7 to provide protection for stable operation of the hydraulic system. The above-mentioned hydraulic station is mobile, has multiple oil path outputs, can meet the application of multiple scenes, and is simple to operate, has high integration, and occupies small space.

[0042] Not limited to this, any change or replacement not thought of through creative labor should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be limited by the protection scope defined in the claims.
