Fangyuan Shipbuilding has made breakthroughs in ship water supply and energy saving technology
An energy-saving automatic speed regulation water supply device belongs to the technical field of ship water supply equipment. At present, the ship water supply generally adopts a pressure water tank type or a gravity water tank type, that is, water is pumped from a water source into a pressure water tank or a gravity water tank to supply water to the pipe network. The pressure water tank has defects such as insufficient water consumption, low water supply quality, and even oil mist of the organic cabin. The gravity water tank must be placed at a high level in the ship, the installation location is limited, and the maintenance management is not convenient for management. Since passenger ships and passenger rolling ships only supply water to the crew when they are moored, the water consumption is small, and there are many passengers during operation, the number of passengers changes greatly, the water consumption is large, and the water use cycle is irregular. There are water consumption peaks and low water use conditions. In addition to the different passenger groups, the quality of water is high, and the pressure water tank or gravity water supply cannot meet the water requirements of large changes.
The utility model can automatically adjust the water supply quantity of the water pump according to the demand of water consumption, and the water pump directly extracts the supply from the fresh water tank, without passing through the pressure cabinet, and there is no secondary pollution of the oil and gas in the engine room. Through frequency conversion control, the frequency and speed of the motor can be automatically adjusted according to the amount of power consumption, and the running power of the motor can be reduced. The structure is compact and the operation is convenient, and the water supply device can selectively use one, two or three full use. Good selectivity and flexible use.
1ton -10ton Endless Round Sling
Polyester round sling is a versatile, convenient, and cost-effective way to lift a variety of cargo.
Manufactured in the CHINA from a continuous loop of polyester yarn, round slings are covered with a durable polyester fabric that is color-coded by capacity. The flexible, pliable design of a round sling allows it to adjust to the contours and hug a load better than other types of lifting slings. The round sling polyester fabric has less stretch than a nylon lifting sling, which prevents the sling from locking up on the load when used in a choker hitch. Because polyester round slings are manufactured using a continuous strand of polyester fiber, it creates exceptional strength. Both eye & eye and endless round slings can be used in vertical, choker, or basket hitches, so they're ideal for a wide variety of applications.
