1、 The core technological advantages of LISICO online viscometer
The reason why LISICO online viscometer can play an important role in lubricant production is due to its excellent technical characteristics that can adapt to the complex working conditions of lubricant production.
Firstly, it has real-time and precise detection capability. This viscometer adopts advanced vibration detection principle, with sensors directly inserted into pipelines or reaction vessels in the production process, capable of capturing subtle changes in lubricating oil viscosity in real time. The measurement accuracy reaches 1.0% of the reading, and the repeatability is better than 0.5% of the reading. Whether it is the blending stage of the base oil or the viscosity changes after the addition of additives, they can be accurately sensed, providing timely and accurate data support for production process adjustments and avoiding product quality fluctuations caused by delayed detection.
Secondly, it has strong anti-interference ability. In the production process of lubricating oil, there are often interference factors such as temperature fluctuations, impurity mixing, and fluid turbulence. Traditional detection equipment is easily affected by these factors, resulting in distorted detection data. The LISICO online viscometer is designed with a special sensor structure to effectively resist interference from external factors such as temperature, pressure, and flow rate. For example, its built-in temperature sensor can real-time collect fluid temperature and perform viscosity temperature compensation to ensure accurate detection results under different temperature conditions.
Furthermore, it has stable and reliable operational performance. The device uses high-quality corrosion-resistant and high-temperature resistant materials to make the sensor probe, which can withstand high temperatures (up to 300 ℃) and high pressures (up to 34.5MPa) in the production of lubricating oil. The probe is not easy to scale or block, reducing the frequency of equipment maintenance and downtime.
2、 Application of LISICO online viscometer in various stages of lubricant production
1. Refining process of base oil
The viscosity of base oil is a key factor determining the basic performance of lubricating oil products. In the refining process of base oil, it is necessary to strictly control the viscosity index of base oil to ensure that the quality of the subsequently blended lubricating oil products meets the standards. The LISICO online viscometer can be installed on the outlet pipeline of the base oil refining tower to monitor the viscosity changes of the refined base oil in real time. When the viscosity of the base oil deviates from the set range, the control system can automatically adjust the process parameters such as temperature, pressure, and reflux ratio of the refining tower based on the feedback data from the viscosity meter, achieving precise control of the base oil viscosity. For example, when the viscosity of the base oil is high, the refining tower temperature can be appropriately increased to promote the decomposition of high viscosity components in the base oil; When the viscosity is low, reduce the temperature or adjust the reflux ratio to reduce the volatilization of light components, thereby ensuring that the viscosity of the base oil is always in the qualified range, laying a good foundation for subsequent production.
2. Lubricating oil blending process
Lubricating oil blending is a key process of mixing base oil with various additives in a certain proportion to form different types and performance lubricating oil products. The real-time control of viscosity during the blending process directly determines the quality stability of the final product. LISICO online viscometer can be directly installed in the blending kettle or on the conveying pipeline after blending, to monitor the viscosity changes of lubricating oil in real time during the blending process. In the initial stage of blending, when the base oil and additives are first mixed, there will be significant fluctuations in viscosity. The viscometer can capture this change in real time and transmit the data to the blending control system. The control system automatically adjusts the addition ratio and mixing speed of each component based on the preset product viscosity formula. For example, when blending multi-stage lubricating oil, if the real-time viscosity is lower than the target value, the system can automatically increase the amount of high viscosity base oil or thickening agent added; If the viscosity is higher than the target value, increase the proportion of low viscosity base oil to ensure that the viscosity of the lubricating oil always approaches the target value during the blending process. In addition, due to the real-time feedback of the blending effect of the online viscometer, the drawbacks of traditional blending processes that require multiple sampling, offline detection, and repeated adjustments are avoided, greatly shortening the blending cycle, improving production efficiency, and reducing raw material waste caused by improper blending.
3. Quality inspection process before product filling
Before filling lubricating oil products, it is necessary to conduct final viscosity testing to ensure that the products meet the factory standards. The traditional offline sampling inspection method has the problem of insufficient sampling representativeness, which may lead to unqualified products entering the market and affecting the reputation of the enterprise. LISICO online viscometer can be installed on the inlet pipeline of the filling line to perform real-time and comprehensive viscosity testing on each batch and bottle of lubricating oil to be filled. Once the viscosity of the lubricating oil at a certain moment does not meet the standard, the equipment will immediately issue an alarm signal and trigger the automatic shutdown device of the filling line to prevent unqualified products from entering the filling process. Through this real-time and comprehensive quality inspection method, the risk of unqualified products leaving the factory has been effectively eliminated, and the level of product quality control in the enterprise has been improved.
3、 LISICO online viscometer helps lubricant factories improve quality and efficiency
The widespread application of LISICO online viscometer in lubricant production can bring significant results to enterprises in various aspects, becoming an important help for enterprises to reduce costs, increase efficiency, and enhance competitiveness.
In terms of product quality, through real-time and precise viscosity control, the viscosity qualification rate of lubricating oil products has been significantly improved, the stability of product quality has been significantly improved, the customer complaint rate has been significantly reduced, and the brand influence of the enterprise has been further enhanced.
In terms of production efficiency, the application of this equipment has significantly shortened the production cycle and reduced downtime for maintenance. Taking the blending process as an example, traditional blending techniques require 3-5 offline inspections per batch, with each inspection taking about 30 minutes. However, with the use of LISICO online viscometer, real-time inspection and adjustment can be achieved, greatly improving production efficiency. At the same time, the stable operational performance of the equipment reduces maintenance frequency, significantly reducing downtime for maintenance each year, creating more production time and economic benefits for the enterprise.
In terms of cost control, on the one hand, precise viscosity control avoids raw material waste caused by unqualified viscosity. On the other hand, the low maintenance requirements of the equipment reduce maintenance costs.
4、 Summary
LISICO online viscometer plays an irreplaceable role in the refining, blending, and pre filling quality inspection of lubricating oil production, thanks to its real-time accuracy, strong anti-interference ability, and stable operation. It has brought significant quality improvement, efficiency enhancement, and cost reduction effects to enterprises. In addition, in addition to traditional mineral oil lubricant production, LISICO online viscometers also play an important role in the production of new lubricants such as synthetic lubricants and biodegradable lubricants. The production process of new lubricants is more complex and requires higher precision in viscosity control. The LISICO online viscometer can meet the special needs of new lubricant production, providing strong support for its research and industrialization.
