Application Case of Chemical Mixing Equipment of Liaoning Huajin Chemical Group Co., Ltd.

Liaoning Huajin Chemical Group was developed on the basis of Liaohe Fertilizer Plant.Liaohe Fertilizer Factory was one of the first 13 large-scale fertilizer factories introduced in China in the 1970s.Since it was put into operation in 1976, it has established the largest self-financing in Liaoning Province, while focusing on factory production and enterprise upgrading.Project—Panjin Ethylene Project.Established compound fertilizer factory, plastic product factory, thermal power plant and other projects, and the enterprise group was established at the end of 1994; in the late 1990s, implemented the capital operation strategy, and initiated the establishment of Liaotong Chemical Industry Co., Ltd. with all the operating assets of Liaohe Fertilizer Factory as its equity Co., Ltd. and completed the stock listing, acquired Jinxi Natural Gas Chemical Plant, established a million-ton-level chemical fertilizer holding listed subsidiary, completed the overall acquisition of Panjin Ethylene, realized 'debt-to-equity swap', and expanded the production and operation of polyolefins. Become the largest chemical company in the province.

It is mainly based on chemical fertilizers and synthetic resins, and is a large state-owned chemical enterprise operating across regions.

The company is headquartered in Panjin City, Liaoning Province, and has three production bases in Panjin City, Liaoning Province, Huludao City, Liaoning Province and Aksu, Xinjiang.It owns Liaoning Huajin Tongda Chemical Co., Ltd. ('Liaotong Chemical' for short, code 000059), its subsidiaries Panjin Ethylene Co., Ltd., Panjin Shuangxing Engineering Plastics Co., Ltd., and Panjin Liaohe Futeng Thermal Engineering Co., Ltd.Power Co., Ltd., Panjin South Chemical Liaohe Catalyst Co., Ltd., Huajin Plastic Products Co., Ltd. have more than ten subsidiaries and branches.They rank among the top 500 Chinese companies and one of the top 100 Sinopec companies.

The company has total assets of nearly 10 billion yuan and 10,332 employees.

Both cylindrical gear reducer and bevel gear reducer are bevel gear reducers.Among them, the cylindrical gear reducer is the most widely used of all basic speed machines.The transmission power range can be from very small to 4000kW, and the peripheral speed can also be from very low (v≤8m/s) to 60~70m/s.The position of the input shaft and output shaft of the bevel gear reducer is configured at 90°, so it is suitable for the case where the input shaft and output shaft are perpendicular to each other.

1. The main features of the gear reducer are high efficiency, durability and easy maintenance.According to the number of stages of the reducer, it can be divided into single-stage, two-stage, three-stage or even multi-stage.According to the mutual configuration of axes in space, it can be divided into vertical and horizontal.According to the characteristics of its motion diagram, it can be divided into expansion type, coaxial type and split type.

In order to avoid too large Dimensions of the reducer, usually when the transmission ratio is lower than 8, a single-stage gear basic speed machine should be used.When it is greater than 8, it is better to choose two-stage (i=8~40) and two-stage or more (i>40) gear reducers.

(2) Worm gear reducers are mainly used in occasions where the transmission ratio is large (i> 10).It has the advantages of compact transmission structure, small Dimensions, and stable operation, but its efficiency is low, so single-stage worm reducers are used more.Two-stage worm reducers are rarely used.The transmission ratio range of a single-stage worm reducer is generally i = 10~-70.

(3) The biggest feature of planetary gear reducer is high transmission efficiency, wide range of transmission ratio, transmission power from 10W to 50000kW, and its volume and weight are much smaller than ordinary gear reducer and worm reducer.However, its structure is more complex, and the requirements for manufacturing precision are also higher.
