1. Main purpose of WAL series insulator horizontal tensile testing machine

1. WAL series insulator horizontal tensile testing machine is mainly used for the tensile test of insulators. It can also be used for lifting belts, chains and ropes as special equipment for tensile testing of products one by one. Extensive load, destruction and other tests require flexible and convenient operation, slow and stable loading, and strong body carrying capacity.

2. Adopting the frame structure of the whole steel plate welded frame, single rod double acting servo cylinder exerts test force, cylindrical pin inserts the sample, load cell measuring force, the tensile space can be adjusted according to the length of sample specification, computer The screen controls and displays the test force and test curve, and automatically processes the test data according to the requirements of the test method.　　

2. Performance characteristics of WAL series insulator horizontal tensile testing machine　
1. Host:

1) The machine body adopts a steel plate welded finishing frame structure, and the main structure of the system is composed of front and rear chuck seats, cylinders and front beams;

2) The rear chuck seat adopts manual push mode to adjust the test space in stages;

3) The appearance of the main machine is designed on the basis of meeting the technical requirements of the horizontal test equipment. The shape is simple and bright, the proportion is coordinated, and the color matching is reasonable, so that the stability, safety and aesthetics of the test equipment are perfectly unified.

2. Oil source system (pump station):

1) The overall modular design of the servo-hydraulic pressure boosting system adopts domestic well-known brand motors, and is controlled by high-pressure gear pumps and servo valves;

2) Fuel tank: fully enclosed standard fuel tank, equipped with oil temperature gauge, level gauge, precision high pressure filter, air filter, etc., and equipped with oil temperature, liquid level, oil resistance protection and indicating devices;

3) Insulator horizontal tensile testing machine has automatic shutdown or alarm functions such as temperature over limit, oil filter blockage, and low liquid level;

4) Piping system: The hydraulic pipelines of the main cylinder loader and the chuck actuator are connected by high-pressure hoses.

3. Control system:

1) The dual-channel control board all adopts digital circuits with the same structure, which improves the interchangeability of each channel;

2) The computer screen completes the integrated data control display and test curve display functions;

3) The data storage function is complete, which can perform historical data reproduction and graphic display;
