The newly revised access conditions will be implemented from October 1, 2012, and the original access conditions will be abolished at the same time. Compared with the “Fiber Fiber Industry Access Conditions” issued in 2007, the revised “Entry Conditions” have comprehensively improved the thresholds for enterprise layout, process equipment, energy consumption, environmental protection, etc., and increased product quality. Access requirements.

In terms of process and equipment, the “Entry Conditions” clearly stipulates that the new alkali-free glass fiber kiln roving drawing production line (monofilament diameter >9 microns) should be 50,000 tons/year or more, and the new fine yarn drawing production line (single) The diameter of the single kiln should be 30,000 tons/year and above. It is strictly forbidden to build and expand the medium-alkali glass fiber kiln wire drawing production line.

New high-performance or special glass fiber production line, its production scale kiln method single kiln should reach 20,000 tons / year and above, the platinum-iridium method should reach 2000 tons / year and above and the product monofilament diameter ≤ 7 microns. The new glass fiber kiln method wire drawing production line should adopt advanced technology and equipment such as pure oxygen combustion, electric fluxing, logistics automation, exhaust gas waste heat utilization, and simultaneously build environmental protection and safe production supporting facilities.

In terms of energy consumption, the “Entry Conditions” require that the unit energy consumption roving of the newly built or rebuilt fiberglass kiln wire drawing production line is ≤0.55 tons of standard coal/ton yarn, and the single yarn diameter of 4 to 9 microns is ≤0.75 ton of standard coal. / ton of yarn.

The new integrated high-performance or special glass fiber-based platinum-ruthenium wire drawing production line has a comprehensive energy consumption of ≤0.37 tons of standard coal/tonne yarn. The glass kiln must adopt advanced kiln melting process and heat preservation technology. The unitless energy consumption of the alkali-free glass kiln unit is ≤0.4 tons of standard coal/ton ball. The comprehensive energy consumption of the medium alkali glass kiln unit is ≤0.3 tons of standard coal/ton ball.

Lifting And Traction Winch

According to different methods of use, winches can be divided into four types: manual winches, electric winches, pneumatic winches, and hydraulic winches. At present, the largest marine hydraulic winch is 350T, and the weight of the equipment reaches 150T.
According to the reel form, it is divided into single reel and double reel.
According to the reel distribution, there are parallel double reels and front and rear double reels.
The main technical indicators of hydraulic winches include rated load, supporting load, rope speed, rope capacity, etc.
A winch is a light and small lifting device (see hoisting machinery) that uses a reel to wind a wire rope or chain to lift or tow heavy objects, also known as a hoist. The winch can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding volume and convenient displacement. The winch is also known as the hoist. The product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient transfer. It is widely used in construction, water conservancy projects, forestry, mines, docks, etc. for material lifting or flat towing, and can also be used as modern electronic control Supporting equipment for automatic operation line.
According to the power, the winch is divided into three categories: manual, electric and hydraulic.
The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet wheel and pawl), which can keep the heavy object in the required position. The manual winch used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used in places where the lifting capacity is small, the facilities are poor, or where there is no power supply.
Electric winches are widely used in places with heavy work and large traction requirements. The electric motor of the single-drum electric winch (pictured) drives the drum through the reducer, and a brake is installed between the electric motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotation, there are also double-drum and multi-drum winches. Generally, a winch with a rated load lower than 10T can be designed as an electric winch.
The hydraulic winch is mainly a winch with a larger rated load. Generally, the winch from 10T to 5000T is designed as a hydraulic winch. The winch can be divided into:
Marine winches: Marine winches can be divided into drag winches, mooring winches, anchor winches, traction winches, etc.
Engineering winch: Mainly used in engineering, with functions such as hoisting and hoisting as the main function.
Mine winches: divided into hoisting winches, dispatching winches, shaft sinking winches, column return winches, rake mine winches, column return winches, etc.
Cable winch: mainly used when laying cables.
