1、 The purpose and scope of application of container bag testing machine

The products produced by our company 200 The series of microcomputer controlled flexible container bag testing machines is mainly used for the testing of container bagsLifting test, repeated lifting, used to determine the safety factor of the container bag and whether it is qualified; Check if the contents areThere are abnormal situations such as overflow, damage to the bag body and connecting parts.

satisfy 1The《GB/T 10454-2000 In the standard of "Container Bags": Periodic lifting test;Pressure testrequirement.

2The《SNT1259-2003 Inspection Regulations for Export Flexible Container Bags 6.2.1 Mentioned in itSecurity DepartmentThe experimental method for numbers.

This machine adopts high-precision load sensors to measure test force values, and uses a hydraulic servo system to transmit powerThe computer automatically controls, collects, processes, and stores test data, and the printer prints the test results. This device is suitable forSelf inspection in the production and manufacturing of container bags, supervision and inspection by container bag inspection and supervision agencies, as well as other related industriesInspection of similar products in the industry.

2、 Main technical specifications of the testing machine

3、 Important functions and features

1. Periodic lifting test, pressure test, vertical drop test, and safety factor inspection of container bags(Top lifting test), inspect the contents(Simulated object)）Is there any overflow, and are there any bags or connectionsAbnormal situations such as damage occur to determine whether the container bag is qualified.

2. Periodic lifting test for bagging(2 Double load, limited use bag 70 times, disposable bag 30 times, reverseFurther improvement）; Pressure test(4 Double load）; Automatic completion70 Secondly or 30 Secondary cycle test force test; plusConstant load time under pressure≥8h。

3. Container bag safety factor inspection: top lifting test(Maximum load/rated load, 6 Double load, pressurizationConstant load time≥5min)。

4. Automatic control, collection, processing, analysis, statistics, output of test curves and reports.

4. Multiple control methods including automatic load holding, setting, stress and strain control, cyclic control, and self programming controlFormula.

5. Intelligent control mode setting, smooth switching between control modes without impact, smooth loading and unloading.

6. Multiple protection functions: oil cylinder limit protection; Overload overflow protection for hydraulic system; Test force overload protection.

7. Automatic return at the end of the experiment, intelligent, efficient, and fast

4The structural characteristics and working principle of the testing machine (please refer to the product appearance diagram)）

This machine adopts hydraulic servo loading method, with a main engine and an oil station (hydraulic loading system)）Microcomputer Control IIIMost of the components

4.1 Host part:

The host is composed of lifting rings, hangers, hooks, fan plates, etc;

The bottom fan plate is the load-bearing bracket of the entire machine structure, connected with an adjustable pressure plate;

The middle part is a pressure cylinder, and the lower part of the cylinder is connected to a high-precision load sensor that outputs the test force value;The upper part is a fan-shaped hanger, which is hung with electroplated hooks to carry the load of container bags.

4.2 Oil station (hydraulic loading system)

This system adopts high-precision digital servo valves with force closed-loop control function, which can achieve equal load rate loading and equal stress rate loading functions, with high control accuracy and good reliability.

gas station(Hydraulic loading system)）There are high-precision digital servo valves, solenoid valves, relief valves, and oil pump electronicsUnit composition, etc. The oil pump motor group is composed of a high-pressure oil pump connected to the motor, and is the power system of the pump station; The valve group consists of digital servo valves, solenoid valves, and overflow valves, and is the control system of the pump station; They are organically connected, Installed on the fuel tank cover plate. Under the cover plate is the fuel tank, and a level gauge is installed outside the tank to observe the fuel level.

4.3 Microcomputer control part:

1. The microcomputer part is composed ofThe EHC-1000 digital electro-hydraulic measurement and control box consists of a computer and a printer.

2. EHC-1000 digital electro-hydraulic measurement and control box: equipped with a data acquisition card to achieve various data acquisition functions.

3. Computer: Implement data input, control, display, processing, and storage functions, which can be customized according to different needsTest requirements, set different test parameters. Computers can achieve automatic control, processing, and storage functions.

4. Printer: Implement data output function.

4.4 Safety factor test

1. Fill the collection bag with a full load of filling materialApply pressure to six times the load of the container bag. Maintain a very high level

The clock.

2. If the bag is not damaged, leaked, or the sling is not broken after maintaining the load, then the safety factor of the container bag is judged as 6 Twice.
