Utility Model Content

[0003] In order to solve the problem of residual oil for testing, the utility model proposes a vacuum pump oil removal tool, which includes a positioning part and an oil extraction part. The positioning part is provided with a positioning groove, and the bottom of the positioning groove is provided with a positioning oil extraction through hole; the oil extraction part includes an oil extraction pipe, an oil storage tank and an air extraction device, the inlet of the oil extraction pipe is connected to the positioning oil extraction through hole, the outlet of the oil extraction pipe is connected to the top inlet of the oil storage tank, and the air extraction device is connected to the top exhaust port of the oil storage tank. When using the vacuum pump deoiling tool of the present invention to deoil a vacuum pump to be deoiled after performance testing, the vacuum pump to be deoiled is first installed in the positioning groove, and the oil guide shaft of the vacuum pump to be deoiled is inserted into the positioning oil extraction through hole; then the vacuum device is started to extract the gas in the oil storage tank, forming a negative pressure in the oil storage tank, so that the test oil remaining in the pump chamber of the vacuum pump to be deoiled enters the oil extraction pipe with the air flow under the action of the negative pressure and is transported to the oil storage tank until the residual oil is completely extracted. It can be seen that the use of the vacuum pump deoiling tool of the present invention can extract the test oil remaining in the vacuum pump to be deoiled, solves the problem of test oil residue in the vacuum pump, and is simple and convenient to operate.

[0004] Preferably, the positioning member is provided with two positioning pins, which are arranged opposite each other on either side of the positioning slot. Thus, when the vacuum pump to be deoiled is mounted on the positioning member of the vacuum pump deoiling tooling of the present invention, the positioning pins can be used to position the vacuum pump to be deoiled, thereby preventing the vacuum pump to be deoiled from rotating after the vacuum device is activated, which would affect the deoiling efficiency and effect.

[0005] Preferably, the positioning member is provided with an offset oil extraction hole, the inlet of the offset oil extraction hole is located at the edge of the positioning groove, and the outlet of the offset oil extraction hole is located on the side of the positioning member and is connected to the oil extraction pipe through an oil extraction branch pipe. In this way, residual oil can be extracted from different positions in the pump chamber of the vacuum pump to be deoiled at the same time through the positioning oil extraction through hole and the offset oil extraction hole, effectively improving the oil removal efficiency and oil removal effect. Furthermore, the offset oil extraction hole is connected to the positioning oil extraction through hole. In this way, during the deoiling process, the air pressure balance in the offset oil extraction hole and the positioning oil extraction through hole can be used to balance the air pressure at different positions in the pump chamber of the vacuum pump to be deoiled, so that the vacuum pump deoiling tooling of the utility model can be used to extract the residual oil in the pump chamber of the vacuum pump to be deoiled.

[0006] Preferably, the positioning member includes an oil suction sensor alarm, which is installed in a sensor slot on the positioning member. When the vacuum pump to be de-oiled is installed in the positioning slot, the sensing end of the oil suction sensor alarm is inserted into the pump chamber of the vacuum pump to be de-oiled. In this way, during the de-oiling process, the oil suction sensor alarm monitors the residual oil content in the pump chamber of the vacuum pump to be de-oiled in real time. When the residual oil in the pump chamber of the vacuum pump to be de-oiled is completely extracted, the oil suction sensor alarm sounds an alarm, facilitating the operator to promptly replace the vacuum pump to be de-oiled, thereby improving de-oiling efficiency.

[0007] Preferably, the positioning member is mounted on two parallel base frames, and the oil extraction pipe is arranged between the two base frames. Thus, mounting the positioning member on two parallel base frames ensures the stability of the positioning member and allows the oil extraction pipe to be directly arranged below the positioning member, making assembly simple and convenient. It also prevents the positioning member from pressing on the oil extraction pipe and affecting the oil extraction effect.

[0008] Preferably, the air extraction device is a vacuum generator. Thus, the vacuum generator is used as the air extraction device, which is easy to select, easy to assemble and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

When using the vacuum pump deoiling tool of the present invention to deoil the vacuum pump 3 to be deoiled after the performance test, the vacuum pump 3 to be deoiled is first installed in the positioning groove 11, and the oil guide shaft 31 of the vacuum pump 3 to be deoiled is inserted into the positioning oil extraction hole 111; then the air extraction device 23 is started to extract the gas in the oil storage tank 22, forming a negative pressure in the oil storage tank 22, so that the test oil remaining in the pump chamber of the vacuum pump 3 to be deoiled enters the oil extraction pipe 21 with the air flow under the action of the negative pressure and is transported to the oil storage tank 22 until the residual oil is completely extracted. It can be seen that the vacuum pump deoiling tool of the present invention can be used to extract the test oil remaining in the vacuum pump 3 to be deoiled, thereby solving the problem of test oil residue in the vacuum pump, and the operation is simple and convenient. Preferably, two positioning pins 12 are provided on the positioning member 1, and the positioning pins 12 are arranged opposite to each other on both sides of the positioning groove 11. In this way, when the vacuum pump 3 to be deoiled is installed on the positioning member 1 in the vacuum pump deoiling tooling of the present invention, the positioning pin 12 can be used to position the vacuum pump 3 to be deoiled, so as to prevent the vacuum pump 3 to be deoiled from rotating after the vacuum device 23 is started, thereby affecting the deoiling efficiency and deoiling effect. Preferably, an offset oil extraction hole 13 is provided on the positioning member 1, the inlet of the offset oil extraction hole 13 is located at the edge of the positioning groove 11, and the outlet of the offset oil extraction hole 13 is located on the side of the positioning member 1 and is connected to the oil extraction pipe 21 through the oil extraction branch pipe 24.

Preferably, the offset oil extraction hole 13 is connected to the positioning oil extraction through hole 111. In this way, during the deoiling process, the air pressure balance in the offset oil extraction hole 13 and the positioning oil extraction through hole 111 can be used to balance the air pressure at different positions in the pump chamber of the vacuum pump 3 to be deoiled, making it easier for the vacuum pump deoiling tool of the present invention to extract the residual oil from the pump chamber of the vacuum pump 3 to be deoiled. Preferably, the positioning member 1 includes an oil suction sensor alarm 14, which is installed in the sensor groove 15 on the positioning member 1, and when the vacuum pump 3 to be deoiled is installed in the positioning groove 11, the sensing end of the oil suction sensor alarm 14 is inserted into the pump chamber of the vacuum pump 3 to be deoiled.
