Wide-range electric pressure debugging meter

Abstract

The invention discloses a wide-range electric pressure debugging meter. A power switch (7) is connected with an electric motor (1), the electric motor (1) is connected with an oil pump piston (2), the oil pump piston (2) is connected with an oiling port (11) and a pressure cylinder (3), the pressure cylinder (3) is connected with an electric contact voltage meter (8) and a control valve (4), the control valve (4) is connected with a reducing valve (5) and a fine adjustment valve (6), the fine adjustment valve (6) is connected with a standard meter output interface (9) and an adjusted meter output interface (10), and then the pressure debugging meter is formed. The pressure debugging meter is simple in structure, convenient to operate, time-saving, effort-saving, wide in detection range, high in calibration precision, capable of avoiding jumping phenomena during debugging of pressure meters and stable and reliable in working.

Description

technical field [0001] The invention relates to a debugger, in particular to a wide-range electric pressure debugger. Background technique [0002] At present, the pressure gauges are debugged by traditional manual pressurization. The oil pressure enters the adjusted pressure gauge and the standard calibration table, and the number is compared with the standard calibration table for debugging. However, in the actual operation process, the number often jumps. , is not easy to control. Secondly, when debugging pressure gauges with different specifications and ranges, it is necessary to replace the matching standard calibration table for debugging comparison, which is cumbersome to disassemble and assemble, inconvenient to operate, and reduces labor efficiency. Again, after debugging 40-60MPa (600kgf / cm 2 ) for a large-range pressure gauge, it is necessary to manually turn the handle to boost the pressure, which is slow, high-intensity, and low-efficiency, and the frequent ro...

Again, after debugging 40-60MPa (600kgf / cm 2 ) for a large-range pressure gauge, it is necessary to manually turn the handle to boost the pressure, which is slow, high-intensity, and low-efficiency, and the frequent rotation of the handle piston can easily damage the seal and cause oil leakage, resulting in oil stains on the work surface, which is not conducive to the working environment
