Abstract

The invention provides an automatic high pressure proportional adjusting device and adjusting method, and belongs to the technical field of static pressure measurement calibration. The automatic high pressure proportional adjusting device comprises pressure producing equipment (1), a pressurization proportional adjusting part, an oil reservoir (6), a pressure relief proportional adjusting part, an oil discharging container (12) and a pressure sensor (14). Compared with a traditional single-piston variable-volume adjusting mode, the automatic high pressure proportional adjusting device has the advantage that the control speed can be significantly improved.

Description

technical field [0001] The invention relates to a high-pressure automatic proportional adjustment device and an adjustment method, which belong to the technical field of static pressure measurement calibration. Background technique [0002] At present, the common liquid high-pressure standard device is the piston pressure gauge, which is based on Pascal's principle and the principle of static balance. It needs to load standard weights when generating and adjusting the pressure, and it is difficult to realize automatic calibration. During multi-point calibration, the calibration efficiency is low. Although there are already automatic piston pressure gauges with automatic pressurization and automatic weight addition in foreign countries that can realize automatic calibration, these piston pressure gauges are large in size, complex in structure, and expensive, so they are not suitable for on-site calibration. [0003] The oil medium pressure controller is the product of the co...
