Coke is one of the coal chemical product, mainly used in the steel industry and partly used in non-ferrous metal smelting, chemical, machinery, chemical fiber and other industries. Such usage determines that the operation of the coke industry is bound to be affected and constrained by the macro economy.
Since the 21st Century, China's coke production capacity has developed rapidly, but its utilization rate is low. Especially since 2005, the total amount of coke consumption shows a trend of rapid decline. In addition, the coke industry is still facing issues of low concentration.
To this end, China will continue to implement the policy of resolving excess capacity of coal for the needs of reform. The pressure on coking enterprises to reduce production capacity will be even greater. The conditions of coking enterprises are still very severe, and the future may not be promising.
Facing the conditions of reform and reduce production capacity, the coking enterprises have taken measures to decrease cost and increase efficiency from various aspects such as management structure, budget expenditure, industrial structure and cost control. Improving product quality and reducing cost have become the key measures taken by the coking enterprises.
The circulating ammonia system of coking enterprises plays an important role in the whole production process. The circulating ammonia water is mainly used to cool the gas coming out of the coke oven, which is an indispensable process before the purification of the waste gas. Ammonia water has a pungent smell. Once it leaks, it will affect production. In severe cases, it may even lead to suspend production. In addition, ammonia water is corrosive, so the sealing and corrosion resistance of the pump is very important. Besides, the working conditions of high pressure ammonia water require high pressure of the pump outlet, which is also a test for the sealing performance of the pump.
TheDF(P) chemical self-balancing multistage pump made by Changsha Zoomlian Pump has a good performance in fields of sealing and corrosion resistance, and the lift can reach up to 1600 meters, far exceeding the similar products. The self balancing multistage pump made by Zoomlian Pump based on the advanced hydraulic model, which the symmetrical impellers in the rotor parts can be balanced during operation. Therefore, the balancing plate which is easy to wear and fail will be no longer needed. The self balancing multistage pump solves the structural defects of the conventional multistage pump, which not only improves the efficiency, but also greatly reduces the maintenance cost of the pump.
Under the condition of supply side reform, cost reduction and efficiency increase will become essential measures for upgrading the coking enterprises. Zoomlian Pump helps coking coal to upgrade successfully depend on high quality product.
