Precautions for the use of electric hoist brake circuit The electric hoist brake circuit should pay attention to two points in use: First, according to the law, when the power supply is cut off, the armature will generate a high self-inductance electric type, resulting in a large current. Through the armature, it is harmful to the equipment. Therefore, when the brake is reversed, a resistor with a suitable resistance value must be added to the armature circuit to limit the armature current in the reverse braking. Second, when the electrical phase When the speed is close to zero, the reverse power supply should be cut off quickly to avoid armature reversal.

Blasting Glass Beads,Glass beads are used for blasting and polishing purposes, for cleaning the moulds for forging, casting , glass, rubber, etc., for removing of the tensile stress and increasing and improvement of the corrosion resistance and fatigue life of the component such as aircraft engine turbine blades, haft, landing gear, springs etc., for decorative finishing of the component surfaces, etc.It is used for cleaning the turbine, blade and axle of the airplane engine.
Glass bead for jetting has the features of chemical stability, high mechanical intensity and hardness. They can be jetted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity.
-Appearance: colorless transparent sphere, rounded and smooth, no obvious bubbles or impurities
-Usage:
1. used for the metal cleaning and polishing and keep the precision
2. also used for machinery sand blasting,enhancing the surface hardness.
3 .Used for reflective road marking paint glass beads.
ADVANTAGES:
-- Clean and smooth.
-- High mechanical intensity, hardness, flexibility
-- High purity and good quality meet the international standard.
-- Stable chemistry property, not pollute the metal processed.
-- Low breakdown rate, Lower disposal & maintenance costs
