In recent years, China's foundry industry has begun its transformation and entered a new stage of development. With the support of the national and local governments, China's foundry industry will enter a broader world.
It is understood that at present, thanks to the booming development of the foundry industry, the research and development of new and high technologies, and the help given by the international industry, China has established a relatively complete industrial system. China's foundry industry has played a major role in this. The industry’s most primitive and powerful driving force for sustainable development of an industry is the market, which is an issue that needs urgent consideration. The current production level and capability of the foundry industry in China have been greatly improved. The gap between casting products and the international market is gradually decreasing. Due to the high quality and low price of our country's foundry materials, it has greatly promoted the development of the foundry industry in foreign countries.
China's foundry industry and the foundry industry in developed countries have gone hand in hand, but China is still at a relatively low level in energy saving and emission reduction. The developed countries have gradually shifted some high-pollution industries to some developing countries, and have taken effective measures to alleviate the state of atmospheric pollution of those enterprises left behind in the country.
First of all, developed countries have incorporated the circular economy and solid waste laws into the basic laws of the country, and the government also supports this.
Secondly, for pollution control and emission reduction, developed countries have adopted closed systems and reasonable organization of air flow and other measures;
Finally, there are key, hierarchical, and highly efficient energy conservation and emission reductions.
Although China is a great casting country, it still has a long way to go before it becomes a strong country for casting. This depends on the fact that China's casting industry currently has a low level of technology, high energy consumption, and serious pollution emissions. If this can be improved, it can accelerate To lead a strong country in casting, so that our country has a place in the international community.
Marine Electro-hydraulic Windlass
The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.
Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.
The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
