Overview
1. Scope of application
PHF101 lubricating oil ash analyzer is a new generation of intelligent products independently developed by our company. Can be in strict accordance with the relevant provisions of the national standard GB/T508, automatic slow ash, fast ash, bonding index, volatiles and other determination. It can also be applied to a series of heating, burning, or drying processes such as fixed-point constant temperature, timed heating, and the like in other industries. The instrument has the characteristics of high measurement accuracy, high efficiency (energy saving), stable and reliable performance, convenient operation and high degree of automation. Therefore, it is widely used in coal, coking, power, metallurgy, petroleum, chemical and other industries and research departments.
2. Main functions and features
In addition to the test procedures for industrial analysis such as slow gray, fast ash, volatilization, and stickiness that are provided by conventional controllers, a powerful custom setting program (abbreviation: self-selection) has been added, and the self-selection program can be set to 50. Independent program, and each individual program can set different constant temperature and constant temperature time. Powerful, good compatibility, can meet the needs of multiple industries.
When the volatiles were tested, the temperature of 900±10°C was restored in 3 minutes. The authenticity of the recovery temperature and the accuracy of the experimental data were the most important features of the temperature control effect of the product.
The equipment adopts PID algorithm and fuzzy control technology to automatically correct the measurement temperature, automatically trigger the thyristor conduction angle by phase shift, and control the heating power.
The operation platform uses the "button" method to make the experimental operation more reliable, flexible and convenient.
The display uses a Chinese display LCD display, the display information is very rich, intuitive and clear
Highly integrated, fast data acquisition and high accuracy.
It has the function of prompt fault phenomenon and automatic judgment of the cause of the fault. With a variety of circuit protection features.
The furnace body adopts imported materials and the temperature field is even and durable.
The overall structure of the equipment adopts an integrated structure, which is beautiful and easy to maintain.
