30-ton Microcomputer Servo Computer-Controlled Fully Automatic Cement Flexural and Compression Integrated Testing Machine

       I. Purpose of the 30-ton Microcomputer Servo Computer-controlled Fully Automatic Cement Flexural and Compression Integrated Machine

      This machine is manufactured in accordance with the test requirements of JC/T960-2022 "Automatic Pressure Testing Machine for Cement Mortar Strength". It adopts microcomputer control, featuring constant test force, constant stress, and a dual-station test space with force maintenance. The computer realizes functions such as on-screen display of test data and curves, disk storage, and database management. Connecting a printer allows output of test data reports. The product is characterized by high precision, high reliability, and convenient operation.

III. Installation of the 30-ton Microcomputer Servo Computer-controlled Fully Automatic Cement Flexural and Compression Integrated Machine

        During installation, ensure the testing machine is level (levelness ≤0.2/1000). Use a 0.1/1000 frame level to measure the plane of the lower platen. If the horizontal or vertical level exceeds the specification, correct it by adding shims under the base plate, then tighten the anchor bolts.

      Then connect the power cable. The machine's electrical system should have a grounding safety protection device. The power voltage fluctuation should not exceed ±10% of the rated value.

IV. Maintenance and Care of the 30-ton Microcomputer Servo Computer-controlled Fully Automatic Cement Flexural and Compression Integrated Machine

1. The testing machine should be installed in a clean, dry environment with uniform temperature, free from vibrations and corrosive gases.

2. Keep the testing machine clean. Frequently oil parts without protective coatings to prevent rust.

3. Change the oil every six months to a year. When changing oil, thoroughly clean the oil tank and filter. To clean the oil tank, pour kerosene into the tank, then drain it. Repeat this several times until clean, and wipe the tank bottom with a towel. Then add clean hydraulic oil. If the hydraulic oil is found to be severely contaminated and unusable during normal use, replace it immediately. Otherwise, it may accelerate wear of hydraulic components and even affect the accuracy of force values.

Hydraulic oil specifications, recommended based on ambient temperature:

(1) When ambient temperature is 10-20°C, use GB-443-84N46# (equivalent to 30# mechanical oil).

(2) When ambient temperature is 20-30°C, use GB-443-84N86# (equivalent to 40# mechanical oil).

4. When not in use, cover the machine with a plastic cover.
