How to find out the error of the electronic tensile testing machine and what problems with the equipment are abnormal?
The electronic tensile testing machine is suitable for plastic films, composite materials, flexible packaging materials, plastic hoses, adhesives, adhesive tapes, self-adhesives, protective films, release paper, combination covers, metal foils, diaphragms, backing materials, Performance testing of stretching, peeling, deformation, tearing, heat sealing, bonding, puncture force, opening force, low-speed unwinding force, and pulling force of non-woven fabrics, rubber, paper fibers and other products. So, how to pay attention to the error of the electronic tensile testing machine and what problems are abnormal with the equipment? Let's take a look!
How to pay attention to the error of the electronic tensile testing machine and what problems are abnormal in the equipment?
1. How to pay attention to the error of the electronic tensile testing machine
1. The lifting part of the jaw position of the electronic tensile testing machine should be kept clean and lubricated at all times.
2. The iron filings in the jaws and the card plate are cleaned regularly to prevent the occurrence of asynchronous transmission.
3. It is recommended that customers replace the hydraulic oil in time according to the frequency of use to prevent damage to the jaw seat, because the aging of the hydraulic oil will cause impurities to increase.
4. The oil pressure sensor of the electronic tensile test needs to pay attention to the need to raise the upper jaw seat by about 10mm before clamping the sample, which is easy to block the oil circuit.
5. The aging of the seal ring will cause oil leakage at the seal, which can affect the weight of the machine on the force value.
6. The partial asynchrony of the chain or worm gear drive causes the upper and lower jaws to be poorly neutralized, and the seals should be replaced.
7. The levelness of the main unit of the electronic tensile testing machine has a large deviation, and the machine is subject to frequent vibration. The friction between the moving parts will increase, and it will also introduce errors into the equipment, causing the specimen to break outside the marking line.
2. What problems are there with the electronic tensile testing machine is not normal?
1. The color of the paint of the electronic tensile testing machine is not beautiful and generous, the color tone is not soft, the color registration is not coordinated, the boundaries of different colors are not clear, and they contaminate each other.
2. The paint and putty of the electronic tensile testing machine do not have enough strength, can not resist oil and corrosion, and have peeling off.
3. The unfinished surfaces of all parts and accessories of the electronic tensile testing machine are not primed. The rust, sand, oil and other contaminants are not carefully removed before the primer is painted. The painted surface is incomplete, not smooth, uneven and inconsistent in tone, with spots, wrinkles, air bubbles and build-up.
4. There are spots on the surface of electroplated parts, uneven coating, and peeling phenomenon.
5. The surface shade of the blackened parts is uneven, with spots, rust and other phenomena.
6. The various signs on the electronic productivity testing machine are not clear. Signage is not fixed in obvious position. The fixed position of the sign is incorrect, uneven, not firm, and skewed.
7. There are bumps, depressions, roughness and other damages that are not specified in the appearance of the electronic tensile testing machine.
8. The edge of the joint surface of the main parts of the electronic tensile testing machine has obvious dislocation.
The above is how to pay attention to the error of the electronic tensile testing machine and what problems with the equipment are abnormal. I hope it can help you!
