Abstract

The invention relates to a vacuum-pumping oil injecting device. The vacuum-pumping oil injecting device comprises a first valve, a second valve, a third valve, a handheld pipe fitting and a vacuum meter, wherein an oil inlet and a vacuum pump connecting port are respectively arranged in the two ends of the handheld pipe fitting; an oil pressure buffer connecting port and the vacuum meter are arranged in the middle position of the handheld pipe fitting; the oil pressure buffer connecting port is arranged at one end, which is close to the oil inlet, of the handheld pipe fitting; the vacuum meter is arranged at one end, which is close to the vacuum pump connecting port, of the handheld pipe fitting; the first valve is arranged between the oil inlet and the oil pressure buffer connecting port; the second valve is arranged between the oil pressure buffer connecting port and the vacuum meter; and the third valve is arranged between the vacuum meter and the vacuum pump connecting port. The device is small and convenient to carry and has the advantages that oil can be rapidly injected into an oil pressure buffer during opening; and if the needed vacuum degree is not achieved before the oil injection, the vacuum degree among sections can be detected through the vacuum meter before the oil injection and which section is poor in air tightness is rapidly found to solve the problem.

Description

technical field [0001] The invention relates to a vacuum oiling device, in particular to a vacuum oiling device used for an oil pressure buffer. Background technique [0002] At present, most of the spring mechanisms for the opening operation of circuit breakers and switches use oil pressure buffers to achieve opening, such as figure 1 As shown, the oil pressure buffer is 13, and the oil filling in the oil pressure buffer is directly injected through the syringe. Due to the complex structure of the oil pressure buffer, there is a large amount of air inside, and the oil pressure buffer will be damaged due to the existence of air during oil filling. Increased internal pressure is not conducive to oil injection, so the amount of oil injected is sometimes too small, which will cause too small buffer when opening the brake and cause damage to the circuit breaker pull rod of the combined electrical appliance. In order to be able to inject enough oil every time the brake is opened ...
