[0019] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all 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.

[0020] At present, a large amount of oil needs to be injected into the sealed cavity of a large motor. In the prior art, the motor cavity is filled with oil manually, which wastes time and manpower and is inefficient.

[0021] Therefore, the present invention provides a vacuum pump 8 oil filling device that can automatically fill the motor cavity with oil. Figure 1 8 is a schematic diagram of the structure of a vacuum pump 8 oil injection device provided in an embodiment of the present invention. Figure 1 As shown, the device comprises:

[0022] 1. An oil tank 1, wherein the head end (head end cover) of the oil tank 1 is provided with an oil filling port 2, and the tail end (tail end cover) of the oil tank 1 is connected with an oil outlet pipeline 3; when filling with oil, the oil outlet of the oil outlet pipeline 3 is connected with the oil filling port of the oil filling pipeline of the device to be filled with oil;

[0023] The oil tank 1 is a cylindrical structure with a hollow interior. The outer shell of the oil tank 1 is made of pressure-resistant material and has sufficient pressure-bearing capacity. The head end of the oil tank 1 is provided with an oil filling port 2 for filling the oil tank 1 with oil through the oil filling port 2. When the oil tank 1 is not filled with oil or is filled with oil, the oil filling port 2 is sealed by an oil filling port sealing plug 6.

[0024] The head end (head end cover) of the oil tank 1 is also provided with an oil tank handle 7 for carrying the oil tank 1. The design of the oil tank handle 7 of the oil tank 1 enables the operator to conveniently carry and place the oil tank, especially during the oil filling process, which facilitates the adjustment and movement of the oil tank 1. The position of the oil tank handle 7 is designed at the head end of the oil tank 1, making it more convenient to lift and put down the oil tank, reducing the difficulty in operation and improving the comfort of human-computer interaction.

[0025] The tail end (tail end cover) of the oil tank 1 is connected with an oil outlet pipeline 3; when filling oil, the oil outlet of the oil outlet pipeline 3 is sealed by the oil outlet pipeline sealing port plugging cover 5; when filling oil, the oil outlet of the oil outlet pipeline 3 is connected to the oil filling port of the oil filling pipeline of the oil-filled device; wherein, the length of the oil outlet pipeline 3 is not less than 5m; the distance between the oil filling port of the oil filling pipeline and the tail end of the oil tank 1 is equal to the length of the oil outlet pipeline 3. In this way, the oil outlet pipeline 3 can be ensured to be in a naturally drooping state, which is convenient for oil discharge and will not cause the oil outlet pipeline 3 to spiral and bend.

[0026] A bracket 4 is provided at the tail end of the oil tank 1 for supporting the oil tank 1. The oil tank 1 is usually heavy, especially when it is full of oil. The setting of the bracket 4 provides stable support, prevents the oil tank 1 from tilting or being damaged due to weight problems, and ensures the stable operation of the entire device. The bracket 4 can also help the oil tank 1 maintain a correct posture during use to prevent oil spillage or loosening of pipeline connections. Specifically, a bracket 4 for supporting the oil tank 1 is provided under the tail end cover of the oil tank 1, and the bracket 4 includes a support rod and a support ring; the support ring is a circular ring structure, the support ring is placed on a horizontal operating table, and the support rod is provided between the support ring and the tail end cover; the support rod is provided in plurality, and all the support rods are arranged at equal intervals; and the tail end cover, the support rod and the support ring surround to form a truncated cone structure. By providing the bracket 4, the oil tank 1 can be at a certain height, thereby ensuring that the oil outlet pipeline 3 can droop naturally.

[0027] In an optional embodiment, the volume of the oil tank 1 is not less than 5L, ensuring that the oil filling will not be interrupted due to insufficient oil. The large-volume design reduces the frequency of oil filling and improves production efficiency.

[0028] 2. A vacuum pump 8 , which is connected to the oil tank 1 via an air charging pipeline 9 and is used to evacuate the oil tank 1 .

[0029] Specifically, the vacuum pump 8 is connected to the head end (head end cover) of the oil tank 1 through the inflation pipeline 9, and the oil outlet of the oil outlet pipeline 3 connected to the tail end of the oil tank 1 is connected to the oil filling port of the oil filling pipeline of the oil-filled device; when the vacuum pump 8 is working, the inner cavity of the oil tank 1 can be inflated and pressurized through the inflation pipeline 9, so that the pressure value in the oil tank 1 is greater than the ambient pressure value and the pressure value in the oil-filled device (such as the motor cavity), so that the oil in the oil tank 1 automatically fills the oil-filled device (such as the motor cavity) due to the pressure difference. If the vacuum pump 8 keeps working, the oil will be automatically injected into the oil-filled device. When the operator determines that the oil amount in the oil-filled device (such as the motor cavity) reaches the predetermined amount, the vacuum pump 8 is stopped (that is, the power plug 10 is disconnected), the oil filling port sealing plug 6 is opened to exhaust, and after the gas is exhausted, the connection between the oil outlet pipeline 3 and the oil filling pipeline is disconnected.

[0030] In an optional embodiment, a power plug 10 is provided on the vacuum pump 8, which is used to be plugged into a power socket to make the vacuum pump 8 work. When the power plug 10 is unplugged from the power socket, the vacuum pump 8 can stop working. The power of the vacuum pump 8 is not less than 900W, ensuring that sufficient airflow and pressure can be provided, so as to efficiently inflate and pressurize the oil tank once, meet the pressure requirements of the inner cavity of the oil tank, and achieve efficient oil injection in a short time.

[0031] The working process of the present invention is described below by a specific embodiment:

[0032] Open the oil filling port sealing plug 6 of the oil filling port 2 of the oil tank 1, fill the oil tank 1 with oil, and seal the oil filling port 2. Place the oil tank 1 bracket 4 on a relatively horizontal operating table, hold the oil tank handle 7, and place the oil tank 1 on the oil tank 1 bracket 4 so that the oil outlet pipeline 3 of the oil tank 1 is in a naturally drooping state. At this time, the position of the oil tank 1 is higher than the position of the device to be filled with oil. Remove the oil outlet pipeline sealing port plug 5 of the oil outlet pipeline 3 of the oil tank 1, and connect the oil outlet of the oil outlet pipeline 3 with the oil filling port of the oil filling pipeline of the device to be filled with oil. Plug the power plug 10 of the vacuum pump 8 into the power socket, and start the vacuum pump 8 to make it work. The vacuum pump 8 inflates and pressurizes the oil tank 1 through the inflation pipeline 9, so that the pressure value in the oil tank 1 is greater than the pressure value in the oil-filled device (that is, a pressure difference is formed between the oil tank 1 and the oil-filled device). At this time, the oil in the oil tank 1 automatically enters the oil-filled device through the oil outlet pipeline 3 and the oil filling pipeline in turn. The vacuum pump keeps working, and the oil will be automatically injected into the oil-filled device. When the operator determines that the oil amount in the oil-filled device (such as the motor cavity) meets its technical requirements, the vacuum pump 8 is stopped, and the oil filling port sealing plug 6 is opened to exhaust. After the gas is exhausted, the connection between the oil outlet pipeline 3 and the oil filling pipeline is disconnected, that is, the connection between the oil outlet pipeline 3 and the oil-filled device is disconnected, and the entire oil filling process is completed.

[0033] Beneficial effects of the present invention:

[0034] The present invention provides an oil filling device of a vacuum pump 8, which comprises: an oil tank 1, wherein the head end of the oil tank 1 is provided with an oil filling port 2, and the tail end of the oil tank 1 is connected to an oil outlet pipeline 3; when filling with oil, the oil outlet of the oil outlet pipeline 3 is connected to the oil filling port of the oil filling pipeline of the device to be filled with oil; a vacuum pump 8, wherein the vacuum pump 8 is connected to the oil tank 1 through an air filling pipeline 9, and is used to inflate and pressurize the oil tank 1, so that the pressure value in the oil tank 1 is greater than the pressure value in the device to be filled with oil, so that the oil in the oil tank 1 automatically enters the device to be filled with oil due to the pressure difference. The oil tank 1 is pressurized by the vacuum pump 8, so that the oil in the oil tank 1 is automatically injected into the device to be filled with oil due to the pressure difference, which solves the problem of manual oil filling of large motor cavities in the prior art. The device has a simple structure, reduces the complexity of operation and the possibility of human error, and can complete the oil filling task more efficiently.
