Abstract

The invention relates to the technical field of mechanical measurement, and discloses a liquid pressure controller with a replaceable measuring range. Wherein, the controller includes a liquid pressure controller cavity, a pre-press pump, a one-way valve, a main piston pump, an intelligent pressure module, an oil cup and a drive module, and the pre-press pump is connected with the one-way valve and co-located with the main piston pump. In the cavity, the oil cup and the intelligent pressure module are connected to the cavity. The working medium in the oil cup is pressurized by the pre-pressure pump and then filled into the cavity through the one-way valve. The intelligent pressure module detects the hydraulic pressure in the cavity in real time, and the drive module When the detected hydraulic pressure reaches the initial predetermined pressure, output a signal to control the pre-pressure pump to stop pressurization and a signal to control the main piston pump to start pressurization, and the drive module outputs to control the main piston pump according to the detected hydraulic pressure and the target set pressure The speed of pressure regulation and the signal of the adjustment scale make the hydraulic pressure in the chamber reach the target set pressure. Thus, the automatic control of the liquid pressure can be realized, 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...
