Embodiment Construction

[0023] The present invention will be further explained below in conjunction with the drawings and embodiments.

[0024] A kind of centrifuge hydraulic differential speed intelligent control method, which includes the following steps: as attached figure 1 As shown in the first step, in the PLC touch screen all-in-one machine, the pressure signal in the form of 4-20mA is input to the PLC through analog-to-digital conversion, and then the actual pressure is obtained after software tuning;

[0025] The second step is to pass the function CV=tan(α)(P-P1)+CV1, Calculated

[0026] Proportional valve control volume, where:

[0027] CV-Proportional valve control quantity,

[0028] α-Control the sensitivity of the valve,

[0029] P-actual pressure,

[0030] P1-Differential adjustment starting pressure,

[0031] CV1- The proportional valve control value corresponding to P1.

[0032] Function as attached figure 1 Shown:

[0033] among them,

[0034] n 0 Basic speed P1-differential adjustment starting pr...

Abstract

An intelligent control method for the hydraulic differential speed of a centrifuge, which utilizes a PLC touch screen integrated machine combined with a software control function, and utilizes a functional relationship to realize automatic adjustment and control of the hydraulic differential speed of the centrifuge, thereby enhancing the stability of the hydraulic differential speed control of the centrifuge.

Description

Technical field [0001] The invention relates to the technical field of centrifuge hydraulic torque control, in particular to a centrifuge hydraulic differential intelligent control method, which improves the stability of the centrifuge hydraulic differential control. Background technique [0002] The decanter centrifuge is a device that uses the principle of centrifugal separation to separate suspended solids from liquid. The centrifuge has a cylinder that rotates at high speed around its axis, called a drum, which is usually driven by a motor. After the suspension is added to the drum, it is quickly driven to rotate at the same speed as the drum, and the components are separated under the action of centrifugal force and discharged separately. With the continuous development of the chemical, pharmaceutical, and food industries, various materials emerge in an endless stream, and the precision requirements for separation and filtration equipment are getting higher and higher. When...
