Description

Technical Field

[0001] The utility model relates to a circulating hydraulic station oil tank, in particular to a circulating hydraulic station oil tank with an oil return confirmation mechanism suitable for full-automatic equipment. Background Art

[0002] Fully automatic bearing vibration measurement equipment requires lubrication of its dynamic and static pressure spindles. These high-precision spindles require pressurized lubricant to operate. Fully automatic bearing vibration measurement equipment operates automatically and unattended most of the time.

[0003] The gear pump in the hydraulic station's oil tank has a limited lifespan and requires regular maintenance. However, existing hydraulic station oil tanks generally require the entire lid to be opened for repair, making operation inconvenient. Furthermore, existing hydraulic station oil tank oil circuit systems generally lack an oil return confirmation mechanism. When the hydraulic station oil tank malfunctions, such as an oil pump failure, oil circuit blockage, insufficient oil in the tank, or insufficient oil pressure, the spindle can rotate without lubricating oil, causing spindle wear. Some existing hydraulic station oil tanks are also equipped with an oil return confirmation mechanism, but these mechanisms present problems such as complexity, lack of stability, and high cost. Utility Model Content

The design of the oil float enables the output of the oil return status signal and the feasibility of the oil return confirmation function.

[0007] Preferably, the three-way connector is also connected to an eighth pipeline, the eighth pipeline is connected to the second pipeline through a cover plate, the second pipeline is connected to a pressure gauge, and the pressure gauge is connected to a pressure relay.

[0008] Preferably, a liquid level gauge is installed on the side of the oil tank body.

DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0015] like Figure 1 、 2As shown, a circulating hydraulic station oil tank has a structure including an oil tank body 1, a cover plate 2 is provided on the top of the oil tank body 1, a mounting plate 4 is installed at the notch on the cover plate 2, a motor 6 and a gear pump 22 are installed on the top and bottom of the mounting plate 4, one end of the sixth pipe 16 extends into the oil tank body 1, and the other end is connected to the first pipe 5 above the mounting plate 4, the first pipe 5 is connected to the three-way connector 18 in the oil tank body 1 below the cover plate 2, the three-way connector 18 is connected to the seventh pipe 17, the seventh pipe 17 is connected to the filter 3 on the cover plate 2, the filter 3 is connected to the fifth pipe 15, the fifth pipe 15 is connected to the dynamic and static pressure spindle oil supply end through the third pipe 12, the three-way connector 18 is also connected to the overflow valve 20 through the ninth pipe 21, a raised portion is provided on the cover plate 2, two ends of the pipe 13 are respectively connected to the dynamic and static pressure spindle oil return end and the raised portion of the cover plate 2, and an oil float 14 is also installed on the raised portion of the cover plate 2.

[0016] As an auxiliary structure, the three-way connector 18 is also connected to the eighth pipe 19, the eighth pipe 19 is connected to the second pipe 10 through the cover plate 2, the second pipe 10 is connected to the pressure gauge 7, the pressure gauge 7 is connected to the pressure relay 8, a liquid level gauge 11 is installed on the side of the fuel tank body 1, and a refueling port 9 is provided on the cover plate 2.

[0017] When the hydraulic station tank is used for oil supply, the oil float 14 can preferably be connected to a signal receiving device such as a touch screen or industrial computer. During operation, the device is started, and the gear pump 22 begins to work to output pressure oil. The pressure oil flows through the sixth pipeline 16 and the first pipeline 5 to the three-way connector 18. The pressure oil flows through the three-way connector 18 to three locations: one is to the pressure gauge 7 and pressure relay 8 through the eighth pipeline 19, so that they can display the pressure value and output the pressure signal; the other is to the dynamic and static pressure spindles through the seventh pipeline 17, through the filter 3, and then through the fifth pipeline 15 and the third pipeline 12; and the other is to the relief valve 20 through the ninth pipe 21. Rotating the handle of the relief valve 20 can adjust the output oil pressure of the third pipeline 12. The return oil of the dynamic and static pressure spindles flows back into the oil tank body 1 through the fourth pipe 13. At this time, the float ball of the oil float 14 floats up, and a normal oil return signal (i.e., a signal of sufficient oil return) can be output to the receiving device. On the contrary, if the float ball of the oil float 14 does not float up, an abnormal oil return signal (i.e., a signal of insufficient oil return) is output to the receiving device, and corresponding processing can be carried out in time.

[0018] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
