Abstract

The invention relates to the technical field of mechanical metering, and discloses a liquid pressure controller with a replaceable measuring range. The liquid pressure controller comprises a liquid pressure controller cavity body, a pre-pressing pump, a one-way valve, a main piston pump, an intelligent pressure module, an oil cup and a driving module, the pre-pressing pump is connected with the one-way valve, the pre-pressing pump and the main piston pump are jointly arranged in the cavity body, the oil cup and the intelligent pressure module are connected with the cavity body, a working medium in the oil cup is pressurized by the pre-pressing pump and then is filled into the cavity body through the one-way valve, the intelligent pressure module detects hydraulic pressure in the cavity body in real time, the driving module outputs a signal for controlling the pre-pressing pump to stop pressurizing and a signal for controlling the main piston pump to start pressurizing under the condition that the detected hydraulic pressure reaches initial preset pressure, and the driving module outputs a signal for controlling the pressure regulating speed and the regulating scale of the main piston pump according to the detected hydraulic pressure and the target set pressure, so that the hydraulic pressure in the cavity body reaches the target set pressure. Therefore, automatic control over the liquid pressure can be achieved, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement, in particular to a liquid pressure controller with a replaceable measuring range. Background technique [0002] The existing main hydraulic controllers all have built-in hydraulic sensor modules, which cannot be disassembled, and their pressure control range is fixed and cannot be changed. Depending on the range of hydraulic control in the work, multiple hydraulic controllers may be required, which seriously affects work efficiency and increases the investment in equipment purchase funds, causing great inconvenience in work. Moreover, the control of the hydraulic pressure requires corresponding operators to control according to the measurement results of the hydraulic sensor module, and the workload is heavy and the efficiency is low. Contents of the invention [0003] The invention provides a liquid pressure controller with a replaceable measuring range, which can solve the tec...
