The thread is changed from the original turning to the rolling method to improve the machining accuracy and strength of the bolt working surface. In addition, the liquid ammonia pump packing is divided into main filler and auxiliary filler before and after the improvement of the pressure cap bolt, and the water is sealed between the main and auxiliary fillers. The original clean water is discharged to the trench directly after being used once. This leads to the loss of a large amount of ammonia, which is also extremely detrimental to environmentally friendly production. In order to change the status quo, on the one hand, the improvement of the main filler was strengthened, and the carbon fiber PTFE woven filler was selected through repeated tests on the main filler material. In the assembly, the graphite is blown in front of the main filler, and a steel shell guide sleeve of one material is added, and a pressure transmission ring with only glass fiber is added between the fillers to improve the force distribution of the filler. In the use of the filler, the sealed water should be sampled and analyzed regularly, and the packing should be arranged in time. If the washing or ammonia is encountered, the pump body is strictly prohibited from frosting, and the hardening and brittleness of the filler after freezing will be affected to affect its service life. After improvement, the main filler has achieved satisfactory results, and the longest service life is as high as possible. At the same time as the main filler is improved, a new sealed water recovery device is added, and a storage tank and a circulating pump are added to recycle the ammonia pump sealing water. After thickening, the second-stage evaporation surface condensate ammonia water tank is sent. Into the production system for recycling. After the expansion of the investment, the current expansion of the trench will receive good environmental and economic benefits, and lay a solid foundation for zero production of urea production.
