Introduction Desulfurization pump process parameters 2. Pump structure 3. Material advantages 5. Bearing assembly 6. Advanced design tools For details, see the Proceedings of the International Pump Technology Summit. The function of the elevator traction system is to output and transmit power to drive the elevator. It is mainly composed of traction machine, traction wire rope, guide pulley and reverse sheave. The towing machine provides power for the operation of the elevator, which is composed of motor, towing wheel, coupling, reducer and electromagnetic brake. Both ends of the pulling wire are connected to the lift car and counterweight respectively, and the lift car is driven up and down by the friction between the wire rope and the pulling wheel. The guide wheel is used to separate the space between the lift car and the counterweight. The use of compound winding type can also increase the drag force.

Over the past 100 years, a large number of coal-fired power plants have been built to meet the demand for electricity. It is estimated that the world's sulfur emissions from thermal power plant chimneys will reach 60 million tons per year, and this number is still growing at a rate of 3% per year. These sulfur-containing waste gases pose a great environmental hazard. At present, the international community is widely aware of this hazard. And actively take measures to reduce the harm. To this end, FGD has become a core technology in environmental protection technology, and a large number of FGD devices will be built in the next 10 years. 86% of the completed FGD devices are wet desulfurization devices. There are many pump products required in these devices, which are collectively referred to as desulfurization pumps. The process parameters of desulfurization pumps in typical wet desulfurization devices are as follows. Working condition parameter Pre-wash cycle pump Spray circulation pump Mixed feed pump Slurry discharge pump Head / m 20~30 20~35 30~40 20~35 Flow rate Q/(L/s) 150~500 400~4 000 10~40 50~400 Weight concentration C w (%) 2~5 8~18 15~40 10~15 pH value 0~2 4.5~6.5 6.5~14 4.5~6.5 Chloride (ppm) 10 000~40 000 ~60 000 1 000~10 000 300~500 Fluoride (ppm) 1 000~4 000 Wear strength in in Strong in Corrosion strength Strong Strong in in
Second, the technical development status of international desulfurization pumps
The technology of international desulfurization pump products developed rapidly in the late 1990s. Some pump product manufacturers represented by WARMAN have invested a lot of money and strength in such products, which is mainly due to the rapid desulfurization market of environmental protection industry. Driven by development. WARMAN first launched the GSM series of products ... (The following details are omitted)
