Method for achieving online blending of multi-grade hydraulic oil through intelligent injection control

Abstract

The invention relates to a method for achieving online blending of multi-grade hydraulic oil through intelligent injection control. A solid agent lifting machine has a negative pressure suction function, and can suck a solid powder drug from a solid agent measuring tank to a hopper of configuring of the solid powder drug, the solid agent measuring tank has a self-weighing function, and weighs thesolid powder drug falling in a solid agent dispensing tank in real time and feeds back to a control cabinet, a first instantaneous delivery passing through a fluid flowmeter can be fed back to the control cabinet through the fluid flowmeter connected with a liquid agent discharging pump, the first instantaneous delivery passing through the fluid flowmeter can be fed back to the control cabinet through the fluid flowmeter, a second instantaneous delivery passing through a mother liquid dilution flowmeter can be fed back to the control cabinet through the mother liquid dilution flowmeter, the solid agent dispensing tank and a liquid agent dispensing tank can be correspondingly mixed and stirred through an aeration disc of a pulse wind stirrer, the type and proportion of preparation of additives needed to be added in different formula hydraulic oil are stored in the control cabinet, agent adding pumps of corresponding dispensing tanks are automatically controlled to be started, and automatic adjustment is conducted according to dispensing change of hydraulic oil blending amount.

Description

technical field [0001] The invention belongs to the technical field of hydraulic oil blending, and in particular relates to a method for realizing online blending of multiple grades of hydraulic oil through intelligent injection control. Background technique: [0002] Hydraulic oil is generally made by adding additives such as antioxidants, antirust agents, antifoaming agents, and antiwear agents to neutral base oils. There are many types of hydraulic oils according to their uses and properties. Each hydraulic oil has There are many grades, and the types and amounts of additives that need to be added to each grade are different. [0003] At present, the blending process of hydraulic oil is basically in a semi-automatic state. The additive liquid or powder is poured into the preparation tank manually, and then the diluted mother liquor is added, and the agitator is started to stir and mix evenly, and then the metering pump is added to the hydraulic oil blending pipeline. , S...

[0003] At present, the blending process of hydraulic oil is basically in a semi-automatic state. The additive liquid or powder is poured into the preparation tank manually, and then the diluted mother liquor is added, and the agitator is started to stir and mix evenly, and then the metering pump is added to the hydraulic oil blending pipeline. , the dosage of some additives is very large, so this method is labor-intensive, the preparation accuracy is not good, and the additive dosage and conversion of different brands of hydraulic oil are more difficult when blending

[0004] So far, there have been no relevant reports on the method of online blending of multiple grades of hydraulic oil through intelligent injection control
