Correct operation and maintenance of carton compression tester


Today, Shanghai Ditech Instrumentation Technology Co., Ltd. shared with you some knowledge about the carton compressive testing machine. I hope that everyone can understand and understand the carton compressive testing machine in more depth.
Shanghai Dumping Carton Compression Testing Machine is the basic instrument for compressive strength test and stacking strength test performance testing of corrugated boxes and other packaging products. It is ideal for commercial, food industry, research institutes and packaging containers supervision departments. Testing equipment has been recognized and used by more and more testing departments and agencies. The most basic maintenance precautions for carton compression testing machines are listed below:
1. The operator should thoroughly read the instruction manual and strictly observe the operation rules;
2. Maintain the working environment of the tester clean and tidy;
3. When the test machine fails, it should be checked and ruled out by professional personnel.
4. Insist on periodic verification to maintain the excellent technical status of the testing machine. The verification period is generally one year;
5. Irregularly lubricate the moving parts of the testing machine intermittently;
6. When the paper roll is used up or the writing is unclear, replace the paper roll or print ribbon.
7. The two drive screw of carton compressive tester must pay attention to maintain proper lubrication. Lubricating oil should be No. 50 mechanical oil. When refueling, the dust shields at the opening of the two columns must be disassembled, brushed with a brush, and oiled. Liquid does not flow down to degrees.
8. Carton compressive tester drive chain should be timely refueling, lubricating oil using 50 mechanical oil, when refueling, the machine can be tilted back to make the base up, with a brush and enamel brush on the bottom of the base chain, The fluid should not be too much, so that it does not flow down.

The above is some knowledge of the carton compressive testing machine shared by Shanghai Dump Instrumentation Technology Co., Ltd., and we hope that everyone can understand and understand the carton compressive testing machine in more depth.

Flow Control Valve

Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used.

Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic control valves. The hydraulic actuators respond to changes of pressure or flow and will open/close the valve. Automatic control valves do not require an external power source, meaning that the fluid pressure is enough to open and close them.

Automatic control valves include pressure reducing valves, flow control valves, back-pressure sustaining valves, altitude valves, and relief valves.
