Description

Technical Field

[0001] The utility model relates to the field of acid value testers, in particular to a fully automatic tester for the acid value of insulating oil. Background Art

[0002] Insulating oil is a synthetic liquid insulating material, referred to as synthetic oil. The acid value automatic tester is used to determine the acid value of transformer oil and turbine oil.

[0003] Before testing, the fully automatic acid value tester needs to place two glass bottles of test liquid in the storage bin of the instrument, and then insert the suction tube into the bottle. The liquid in the bottle is extracted by the pump body arranged inside the instrument, and then dripped into the test tube filled with insulating oil to measure the acid value. However, when the instrument is not in use, the bottle containing the test liquid is usually taken out of the storage bin for sealed storage. Therefore, the suction tube is usually directly connected to the bottle cap and placed randomly in the storage bin. Since the test liquid needs to be extracted, the suction tube is generally slender. Therefore, when it is placed randomly, it will be squeezed against the inner wall of the storage bin due to accidental collision, causing the suction tube to bend and deform, affecting the subsequent use of the suction tube.
