طرق حفظ المواد عند استخدام المضخات الكيماوية


1. تحسين عملية الصيانة لـمضخة كيميائية، وتقليل الاصطدام الاحتكاكي وفقدان الدوامة بين الماء وجدار قناة التدفق ، وتلميع وتلميع الأجزاء الرئيسية التي لها تأثير أكبر على الكفاءة. يمكن رؤية اللمعان المعدني عن طريق التلميع ، ويجب ألا تتلف قناة التدفق الأصلية. اكتب سطر.

2. Reduce the leakage loss in the مضخة كيميائية, improve the processing accuracy and assembly quality of the parts, reduce the radial clearance of the throttle sleeve in front of the balance disc and the radial clearance of the front and rear seal rings of the impeller and the guide vane seal ring, and reduce the liquid in the مضخة كيميائية Pressure energy loss caused by leakage from the high-pressure side to the low-pressure side. For the impeller sealing ring, guide vane sleeve, front throttling of the balance disc and other parts, materials with higher hardness should be selected, and heat treatment to improve wear resistance should be carried out.

3. When starting the مضخة كيميائية in cold state, the مضخة كيميائية should be fully warmed according to the requirements of the regulations. If the مضخة كيميائية is not warmed enough, a large thermal temperature difference between the upper and lower sides of the مضخة كيميائية is likely to occur, causing the rotor to be bow-shaped. It is easy to start the مضخة كيميائية at this time The internal sealing gap wears large, causing internal leakage and increased volume loss of reflux. When adjusting the load, it must be stable to avoid large fluctuations in feed water pressure, maintain continuous and stable operation of the مضخة كيميائية, and reduce the axial movement of the مضخة كيميائية to avoid wear of the seal gap.

4. Under normal operating conditions, the water discharge door, drain door and مضخة كيميائية body discharge door of the water supply system, the boiler's regular sewage discharge door, and the accident discharge door should be closed tightly, and the door should be cold after touching the inspection door. If the valve is not tight, it should be dealt with in time.

5. The recirculation device for the مضخة كيميائية is used to maintain a minimum flow for the مضخة كيميائية when it is started, just put into operation, and when the boiler water supply is stopped, so as to prevent the small flow and heat generation during operation and the vaporization of the water supply and cause accidents. The recirculation door should be closed tightly during normal operation.
