1. When the lifting is finished or stopped, the drum of the hoist can be reliably braked and stopped normally;
2. Control the running speed of the lifting container, ie the working brake, during the deceleration phase and when placing heavy objects;
3. When an emergency occurs in the hoist, the hoist can be automatically and quickly erected to protect the lifting system, that is, the safety brake;
4. The double drum hoist can lock the swimming roller when replacing the lifting level, replacing the wire rope or adjusting the rope.
Manual Coal Steam Boiler Features
1.The boiler has big drum and have big enough space for water. Compared with the SZL series, the DZL boiler is more adaptable to poor water quality. Moreover , when the boiler scaled, it is convenient for maintenance.
2. Adopting convex tube plate, prevent tube plate cracking and simplify the structure of canceling the tension bar.
3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.
4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in the threaded pipe, avoid the accumulation of dust in the tube.
5. The boiler has sufficient output, fast speed heating and high thermal efficiency.
