Construction guidelines for electrolytic ion grounding:
Step 1. The hole diameter is 0.15m - 0.20m and the depth is at least 3m;
Step 2. Installation Place the grounding electrode in the hole;
Step 3. Connection Connect the copper cable connected to the grounding electrode with other grounding electrodes and use Hotwell welding.
Step 4. Lay the backfill and place it in clean water and backfill in sequence, stir, and then put the electrolytic salt into the container and mix it with paste back into a paste and pour it into the gap around the grounding electrode;
Step 5. Backfill and fill in the fine soil first, layer by layer compaction.
The construction of electrolytic ion earthing pole is simple. The traditional earthing requires a large area of ​​work, and the construction cost, road cost, and road breaking cost are relatively large. Field construction increases the land occupation fee or the compensation for economic crops. When the product does not have outdoor construction conditions, the product can be installed in the interior of the lowest floor of the building. The unipolar area is only 0.1m2, which is especially suitable for building density. Used within the city. The project has low additional cost, long service life and free maintenance for 50 years.
Electrolytic ion grounding electrode application range and application method Electrolytic ion grounding electrode is widely used in grounding of communication, power, petrochemical, finance, network, electronics and other important places due to its good anti-corrosion performance, excellent conductivity and unique design process. The project is especially suitable for grounding projects with poor soil conditions, limited construction conditions, and high technical standards.
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.
