mining Scraper Winch has been widely used in construction materials, chemical industry, etc., especially for lifting bulk materials. The hoisting winch has lower requirements for the type, characteristics and lump of the material; it can improve powdery, granular and lump materials; it can improve the abrasive; and it can raise high temperature materials with a temperature of <250 degrees.
mining Scraper Winch has a large conveying capacity. The lifting capacity can reach 15-800 cubic meters / hour. Low energy consumption. This hoist adopts feeding, gravity induction unloading, and uses densely arranged large-capacity hoppers for transportation. The chain speed is low, the lifting amount is large, and there is almost no return. Therefore, the driving force is small, and the theoretical calculation value of the axial force is 25% -45% of the chain hoist.
lasting. This type of hoist uses inflow feed, which rarely squeezes and collides between materials, and does not disperse during feeding, lifting and unloading, thereby preventing abrasive wear. The conveyor chain uses a chain of high-strength wear-resistant chains to extend the service life of the chain and bucket. The actual use shows that the service life of the conveyor chain exceeds 5 years. This hoist chain has a low speed and stable operation, and a high-strength wear-resistant chain with a plate chain can achieve a higher lifting height.
The advantages of mining winches are mainly reflected in several aspects, affecting their frequency of use and industry.
1 Reduce maintenance and repair costs.
The winch control system with frequency conversion control as the core makes the control performance and protection performance of the winch more perfect.
Compared with the original old electronic control system, the failure rate of the equipment has been reduced by more than 80%, the maintenance rate of the equipment has been reduced by 50%, and the maintenance cost has been reduced by more than 65%, which has greater safety benefits.
2 Mining winches have significant energy saving effects.
The control circuit of mining winch adopts frequency conversion speed regulation system, which has better energy saving effect than the original series resistance speed regulation electronic control system.
The frequency conversion speed regulation system uses vector control technology as the core, which eliminates the input of the original winch string starting resistor, reduces the resistance and voltage drop loss, and saves the power loss of the equipment.
