How to Prolong the Lifespan of Vibration Motor

1. Make sure the wiring and insulation work of vibration motor is well done in order to prevent the lack of phase and short circuit .
2. Anchor bolt reinforcement work should be done frequently, take necessary prevention measures, such as using a double nut fastening to ensure vibration motor base and the floor contact well.
3. Attach great importance to the cover sealing of vibration motor, the dust inside the protection cover should be cleaned up frequently.

4. Strengthen the daily maintenance of vibration motor, remove the dust on the motor surface frequently, and reduce the impact on the vibrating motor due to the poor heat dissipation in order to make it work in a good condition.
5. Please pay attention to the symmetry when adjusting the vibration block, the gravity connection centerline of vibration block on both sides should be parallel to axis.
6. Check whether there is crack on motor appearance, all fastening screws and parts are complete and the fixed situation of the motor are in good condition or not.
7. Check whether the ventilation and bearing lubrication condition of vibration motor is normal or not.
8. Pull out the motor axis and check if rotor can rotate freely and whether there is noise during rotation.
9. Check whether the grounding device is reliable or not. 

Modified of UHMWPE

We can improve the process ability and heat resistance of UHMWPE through mixing it with other resin and adding auxiliaries. With higher performance of UHMWPE, we can produceconveyor rollers, belt conveyor in higher technology and quality. 

1, Modified of liquidity

(1) Mixing UHMWPE with LCP can improve the liquidity and can use the single screw extrusion machining. The more additive amount of LCP, the better of liquidity of mixture. 

(2) Mixing UHMWPE with PE can ensure the good process ability of mixture as the additive volume of PE is below 30%. Besides, it keeps the excellent performance of UHMWPE.

(3) Mixing UHMWPE with PE-WAX, Erythromycin stearate less than 10% and so on.

(4) Add 3-5% layered CADD into UHMWPE, and the melt index can reach 0.2-0.4g/10min.

(5) Add 1% pyrogenic silica into UHMWPE, and the mixture can be nucleating agent of PE to improve the liquidity.

2, Modified of abrasive resistance: Adding the ultrafine molybdenum disulfide, graphite, carbon black, ultrafine glass bead, carbon fiber and PTFE treated by coupling can reduce the friction coefficient and improve abrasive resistance. However, it will improve the friction coefficient to add rubber or PU into UHMWPE.

3, Modified of heat resistance: after treated by plasma crosslinking, the operating temperature of UHMWPE can reach 200℃. And filling inorganic filler treated by coupling in UHMWPE, such as glass fiber, carbon fiber, glass beads, wollastonite, calcium carbonate, talc, mica, graphite, diatomite, copper powder, etc. HDT will improved obviously.

4, Modified of heat conduction: the heat conduction of UHMWPE can be improved by adding copper powder, aluminum powder, lead powder and other metal powder. 

5, Modified of mechanics: the strength, hardness and stiffness of UHMWPE can be improved by adding glass fiber, carbon fiber, superfine glass beads, calcium carbonate, kaolin, talc, mica, needle-like wollastonite, 3 oxidation 2 aluminium and silicon dioxide.
