| 4. Features |
| 4. 01 | The test box is an independently sealed area, isolated from the power area at the bottom and the exhaust lighting area at the top, which can prevent the flame, high temperature gas, leakage gas, etc., from spreading to other areas; |
| 4. 02 | The test box is provided with an exhaust system. The internal exhaust outlet of the box is arranged on the top of the box and equipped with an air collecting hood; The lower left side of the interior of the box is provided with a supplement air outlet; The exhaust fan is composed of a long-axis motor and a steel wind wheel, with large air volume, fire resistance and high temperature resistance |
| 4. 03 | The test box is all composed of high temperature resistant and flame retardant parts (no plastic pipelines, wires, rubber gaskets, sealing rings, lubricating oil, oil, etc.), and the box door is sealed with high temperature resistant seals; |
| 4. 04 | The front door of the test box adopts reinforced design, which can effectively isolate the damage caused by fire and explosion during the test. The door panel adopts a double-layer design with interlayers, and the hinge and door lock adopt reinforced equipment special standard parts. The door window adopts double-layer explosion-proof design tempered glass; |
| 4. 05 | The open side of the backplane of the test chamber uses a hinge and the other side uses a magnetic adsorption movable door, which plays an effective role in blasting. When the backplane is closed, it should be sealed around it to prevent gas leakage in the test box; When there is an explosion inside the box, the high-pressure gas generated can open the pressure relief door to protect other aspects of the equipment from damage and the safety of the test personnel; |
| 4. 06 | The bottom plate of the test box adopts an integrated design, without holes and gaps, which is easy to clean. |
| 4. 07 | The top of the test box is equipped with a lamp, and the tempered glass protective cover is used to protect the outside of the lamp to prevent the flame and ejection from damaging the lamp. Standard detachable fasteners are used to connect the test box for easy disassembly and replacement; |
| 4. 08 | Extrusion testing machine has electrical safety in line with national standards, which can effectively prevent and eliminate electric shock hazards that may occur in operation and maintenance personnel. During normal operation, except for the circuit part of the equipment, the shell of the equipment and the metal parts in the test box will not be charged. In the event of an accident, such as fire, leakage, short circuit, etc., the equipment can automatically cut off the external input power, so that any part of the equipment is not charged; |
| 4. 09 | The extrusion testing machine should have an "emergency stop" button to facilitate emergency treatment in critical situations. The "emergency stop" button is used to stop all actions of the extrusion testing machine in critical cases to prevent the occurrence of hazards; After the "emergency stop" button is reset, the extrusion testing machine is in normal operation state; |
| 4. 10 | The extrusion fixture of the extrusion testing machine can be flexibly disassembled and easily replaced. Available extrusion fixture: flat extrusion disc |
| 4.11 | The extrusion testing machine shall be equipped with a universal roller for easy movement and an adjustable support foot for a fixed position; |
| 4.12 | The extrusion testing machine has the function of self-protection pressure setting, which can prevent excessive extrusion pressure during the extrusion test and damage the equipment. When the extrusion pressure reaches the set protection pressure value, the extrusion testing machine automatically stops. At this time, only the extrusion fixture can be lifted, and the extrusion test cannot be continued. |
