Shaanxi Chemical Industry’s Gasification Plant Successfully Replaced the Water Pump for Dust Suppression Systems Author/Source: Shaanxi Chemical Industry Date: April 25, 2022 Clicks: 5 From April 18th to 19th, the transportation team at Shaanxi Chemical Industry’s Gasification Plant managed to complete the task of replacing the water pump used in the dust suppression systems behind the silos within two days; the dust that had been floating in the air for days finally settled down. The water pump for the dust suppression unit located behind the silo belt is an environmental protection device that primarily uses water misting to prevent coal dust from flying and dispersing. The dust suppression main pump that has been replaced this time has been in use for 11 years; thanks to thorough regular maintenance, it has never required major repairs since it was put into operation. Since March this year, the water pumps have started to experience issues such as insufficient pressure, low flow rate, and poor water atomization, which has affected the dust suppression efficiency and posed a risk to the company’s environmental standards. Therefore, the gasification plant promptly initiated the repair and replacement of the water pumps. The branch factory arranged for relevant technical personnel to get in touch with the manufacturer; both parties conducted a thorough and detailed inspection of the water pump. Based on the results of this inspection, an assessment was made of the pump’s operating condition, and ultimately, they agreed with the manufacturer’s recommendation to replace the pump. At the beginning of the work replacement project, the pandemic situation suddenly became severe, and due to relevant regulations, the manufacturers were not allowed to enter the company to carry out the work. After assessing the technical capabilities of the workshop and the company, the branch factory decided to have the water pumps delivered via logistics, with our team carrying out the installation work. For complex piping sections, video is used during construction, with remote technical support provided by the manufacturer. Thanks to the thorough planning and effective coordination among the team members, the replacement of the water pump was completed in just one day, on the 18th; pressure testing was carried out on the 19th, and everything was a complete success.
