A burette speed regulating titration device

Abstract

The invention discloses a speed-adjustable titrating device of a titrating tube, and the speed-adjustable titrating device aims to solve the defect that test fail as manual titrating operation for the titrating tube easily causes limp and numb, certain titrating speed is very difficult to guarantee by long-time tittering, and a solution easily flows down in the form of line and column. The speed-adjustable titrating device comprises two clamping arms which are hinged together, wherein C-shaped clamping heads are arranged at the front ends of the clamping arms; openings of the two clamping heads are oppositely arranged; anti-sliding pads are arranged on inner walls of the clamping heads; an upper rotary disc and a lower rotary disc are separately arranged on hinged positions of the two clamping arms; a connecting rotary shaft is arranged between the upper rotary disc and the lower rotary disc; a plurality of locking holes are uniformly distributed in the lower rotary disc; and locking rods which are in adaptive connection to the locking holes are further connected on the upper rotary disc. The speed-adjustable titrating device of the titrating tube does not need hands to hold a glass ball all the time in a titrating process, so that titrating speed also can be conveniently controlled through long-time titrating, the solution is prevented from flowing down in the form of line and column, and accuracy of the test is guaranteed.

Description

technical field [0001] The invention relates to a titration test auxiliary device, more specifically, it relates to a burette speed-regulating titration device. Background technique [0002] At present, there are many oil-filled equipment in the power system, such as transformers, current transformers, voltage transformers, bushings, etc. Insulating oil plays the role of heat dissipation, insulation, and isolation protection, and is widely used in power systems. We usually carry out oil testing on oil-filled equipment on a regular basis. The testing items include chromatography, micro water, pressure resistance, acid value and so on. The acidic substances in the oil will increase the conductivity of the oil, reduce the insulation properties of the oil, and will also promote the aging of solid insulating materials and shorten the operating life of the equipment. The acidic substances in the oil also have a corrosive effect on the metal materials such as copper, iron, and alu...

Problems solved by technology

However, the titration process is manually operated and kept at a certain titration speed for a long time. The operation is difficult, and it is easy to cause numbness. Due to the long time and high requirements for strength, people are prone to fatigue, which may cause the solution to flow down in a linear or columnar shape.
