It is advisable to observe the change of the liquid level of the cleaning box by operation. In the use of higher parameters of the cleaning pump, equipped with recirculation door, should be able to observe the back of the general front of the fluid and the main door of the discharge divssure gauge, in order to ensure that the operation can coordinate the divssure of the control system, flow. In the top of the drum to add a hydrogen pipe, generally by the self-use steam port with a diameter of 57mm steel pipe elicited. Hydrogen discharge method generally uses two kinds, one is the timing hydrogen discharge method (after the acid has a certain time interval for hydrogen discharge), the hydrogen discharge pipe is connected to the trench, the other is the continuous hydrogen discharge method. Care should be taken to consider ease of operation. The main valve and the total valve installation position of the discharge fluid when the temporary system valve is installed, the hydrogen discharge pipe is connected directly to the cleaning box (in this way, the drum is maintained after the acid is introduced to lead to the circulation of the hydrogen discharge pipe and the cleaning box). However, regardless of the use of hydrogen discharge method, in the acid discharge must be strict discharge of hydrogen valve, to divvent air entry and produce a large area of two rust, until rinsing and passivation can be discharged air or maintain continuous circulation.
泵的特点:
1、螺母能叶轮间隙,减小漏洞,提率,并使叶轮拆装方便。
2、填料室密封与下端轴承分开,轴承两端采用骨架油封和机械密封,防止泥沙轴承内部,轴承寿命。
3、过流部件采用耐磨铸铁,硬度大,强度高,使用寿命比普通材质长2-3倍。
4、叶轮背面采用了副叶片,使背面压力,减小轴向力及防止部分杂物密封腔,保护密封件少受磨损。
五、使用须知
1、本泵为单极单吸立式离心泵,可垂直或倾斜使用,使用时宜置于双浮筒上,便于在水面或泥沙上推移,浆泵按在双浮筒中间,泵壳放入泥沙中即可,不用基础装置。
2、电机需加防护罩,以防电机沾污、淋湿。
3、不使用时宜清洗、:加油,刷油漆X,收储干燥的,泵体入口应防止杂物落入,泵体宜直立,以防主轴变形。
