Some people maintain solid wood floors, and they are still intact in ten years. Some owners are not good at caring for solid wood floors. The use of solid wood floors for two or three years has no gloss. Among them, moisture protection is an important aspect.
Solid wood flooring is processed from the bottom to the top by a precious wood. The natural property of wood determines that solid wood flooring is easily affected by the weather. Especially on rainy days, the phenomenon of “swelling and shrinking†occurs. The deformation of solid wood flooring, lifting, and arching are inseparable from water.
First of all, when preparing the installation, you should prepare for moisture protection. Do not use splints and woods with high moisture content and install a moisture barrier.
Second, in the rainy weather, especially in the late spring and early summer, we must do a good job of moisture prevention. In the rainy days, the outside air is relatively humid. At this time, the owners should not open the windows. They should close the windows to prevent the moisture from entering the room and affect the solid wood floor. When the indoor moisture is heavy, the windows should be opened for ventilation to drive away the moisture inside the floor. When both internal and external humidity are great, you can dry the surface of the solid wood floor with a dry rag or blow it directly with an electric fan. This is also a way to get rid of moisture.
Finally, it is the usual care and maintenance. The owners are better not to use the wet mop to mop the ground, half-dry mop on it. When the wooden floor was very damp, the relief floor editor reminded everyone that avoiding the use of electric heaters to dry or sun exposure would catalyze the deformation of the floor, and the effect was counter-productive.
Attention to moisture, damage prevention is the secret of solid wood flooring maintenance, do a good job of moisture-proof, anti-damage solid wood flooring will be timeless and prolong life.
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.
