The Type detection method of the Wes hardness meter originated in the United States. In the 1980s, it entered our country with the introduction of the aluminum profile production line.The principle of the Wes hardness meter has a certain shape of a hard steel pressure needle. Press the sample surface under the action of the standard spring test force, and use the pressurization to depth to determine the hardness of the material, and define the pressure depth of 0.01mm.EssenceThe Wes hardness unit is expressed as HW.
Weis hardness meter repair
1. The force of the blade is loose, and you should adjust the force blade and tighten it.2. The wear of the force blade and the fulcrum will increase the load error to varying degrees, and the blade should be trained.3. The position of the adjustment block on the load load leverage is not appropriate. You can move forward or backwards according to the situation.4. Compressed spring rust and increase the friction with the finale and the spindle band. The rusty area should be cleaned and the protective oil or replacement should be cleaned.5. Increased and unstable, there is a phenomenon of impact vibration, which should be excluded.6. The speed of adding loads is too fast or too slow, mainly because the oil viscosity of the reducer is too small or too large. The reducer should be cleaned and the oil use of the reducer should be replaced.7. The switch contact point is burned and obscured, resulting in poor contact point contact, and the contact point should be cleaned up or replaced with a new switch.8. The hardness meter does not move, but there are buzzing current sounds, and the motor is short of phase. Check whether the power supply is normal, whether the power plug is inserted, whether the cable is disconnected, whether the power switch is intact, whether the motor wiring is firmly connected, the motor coil is connected, the motor coilWhether to burn a set and whether the contact contact contact is good, etc., you should exclude it according to its situation.
Weis hardness meter correction
1. Hit.Use the maximum force to use the needle to sit on the anvil, and the pointer is pointing at this time.2. Play standard board.It is best to hit a high -value board, a low -value board, the error is within 0.5.
