我们是以麦草作原料,用亚铵法造纸的小厂。在蒸煮工序,要用泵将液体亚硫酸铵溶液和氨水从地下贮池注入蒸球。由于亚铵溶液和氨水腐蚀性较强,泵的底阀经常损坏泄漏,同时蒸球又是间断性生产,提液泵就要定期开停。因为底阀漏液,每次启动时要人工加引水,操作不便,耽误时间,同时还造成药液浓度不稳定,影响 We are wheat straw as raw materials, the use of ammonium method papermaking small plant. In the cooking process, the liquid ammonium sulphite solution and ammonia water are injected into the steamer from the underground storage tank. Due to the strong corrosivity of ammonium salt solution and ammonia, the leakage of the pump’s bottom valve is often ruptured, and the steamer is intermittent. Because the leakage of the bottom valve, each time you start to manually add water, inconvenient to operate, delay time, but also caused the concentration of liquid chemical instability, the impact
