1. Introduction
The Normal Temperature Intelligent Swell Meter is mainly used to test the hydration and expansion characteristics of mud shale at room temperature and pressure and to evaluate the optimal anti-collapse drilling formula. It is mainly composed of host computer and data sampling system.
The instrument adopts dual channels at normal temperature and pressure, and synchronously compares measurements to reduce test errors, save time, and improve work efficiency. The shale hydration and expansion process can be obtained under different pressure conditions. Provide advanced mud testing equipment for scientific research and production. It greatly reduces the space of the instrument and can be directly connected to the computer. It is an optimal paperless recording method. It has a paper recorder that is longer than the barrel and greatly saves costs. 2. Specification and Model

Normal Temperature Intelligent Swell Meter | NP-02A |
3.Working Principle
Hang the pressed rock sample (with the rock sample cup) together on the hanger and adjust the zero point. Put the liquid cup into the experiment and lift the cup holder to make the liquid cup test solution flow into the test cup. Due to the hydration and expansion characteristics of mud shale, upward displacement is generated, so that the sensor generates a signal and transmits it to the computer, and the displacement is expanded according to time, and the real-time change curve and corresponding digital recording data are recorded.
