Crude oil prices continue to decline
The continuous decline in international crude oil prices led to a drop in the price of domestic chemical products. With the traditional sales season of the chemical industry in the past, the chemical industry is entering a deep adjustment period. According to monitoring, in the October 2013 commodity price fluctuations list, the chemical sector saw a significant increase or decrease, with the overall showing a downward trend.
According to statistics, in the 68 representative products of the chemical sector monitored by the Business Club in October, there were 42 kinds of goods that increased month-on-month, and there were 9 kinds of goods that increased by more than 5%, accounting for 8.2% of the monitored goods in the sector; There were 62 kinds of commodities with a month-on-month decrease, and 7 kinds of products with a decrease of more than 5%, which accounted for 6.4% of the monitored commodities; the top three products were crude benzene (-9.82%) and PTFE. Dispersion resin (-9.16%), styrene (-8.31%).
In October, the number of rising chemical varieties in the chemical sector was 12 fewer than in September, and the number of falling varieties was 15 more than in September. Business community chemical industry analyst Zhang Ming said that due to the negative accumulation in the market since mid-October, the international crude oil continued to decline, organic chemical product cost support is insufficient, under the oppression of downstream users and distributors were forced to lower the offer level by level, therefore, In the top spot of the gains list, rare organic products were found. **, toluene, and xylene were removed from the rising camp. Even if the number of rising propylene camps, phenol, propane, acrylic acid, and other products rose, they were extremely weak.
"The lack of organic product cost support, the traditional sales season in the chemical industry has passed, in November the domestic chemical market will enter the depth of the consolidation phase." Zhang Ming believes that the lack of domestic domestic demand release will become the chemical industry will face an important issue in the future. In October, the sharp drop in the price of calcium carbide was mainly hampered by the negative purchases of downstream polyvinyl chloride (PVC) companies. At the same time, the sluggish international market cannot boost domestic market conditions.
Liang Bin, an analyst at CSC Chemical Industry, believes that the continued decline in chemical product prices indicates that the current market demand is weak, and the market is worried about the uncertainty of future demand. As the market entered the off-season, demand fell back to expectations. Lack of demand, the role of cost-end price is particularly important, while crude oil is affected by weak demand and increased inventory, and the future price trend of chemicals is still not optimistic.
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.
