التجميع الحامل: تتبنى مجموعة الحامل لمضخة الحصى الرملية بنية أسطواني ، وهو مناسب لضبط الفجوة بين المكره وجسم المضخة ، ويمكن إزالته ككل أثناء الصيانة. المحامل مشحبة الشحوم.

الأداء العام لمضخة الحصى الرملية: تتكون مادة الأجزاء الزائدة من الحديد الزهر العالي المقاومة للبلى. تحتوي المضخة على قناة تدفق واسعة ، وأداء التجويف الجيد ، وكفاءة عالية ومقاومة التآكل. يتم استخدام سرعات ومتغيرات مختلفة للسماح للمضخة بالعمل في ظل ظروف التصميم. لديها عمر خدمة طويلة وكفاءة تشغيل عالية ، ويمكن أن تلبي العديد من أنواع الشروط القاسية

1. ظاهرة التجويف للمضخة:


عندما يكون السائل في درجة حرارة معينة ويتم تقليل الضغط إلى ضغط التبخير عند درجة الحرارة هذه ، سينتج السائل فقاعات. وتسمى هذه الظاهرة لتوليد الفقاعات التجويف. عندما تتولد الفقاعات أثناء تدفق التجويف إلى مكان الضغط العالي ، ينخفض ​​حجمها حتى ينفجر. وتسمى هذه الظاهرة من الفقاعات التي تختفي في سائل بسبب ارتفاع الضغط انهيار التجويف.


عندما تكون المضخة قيد التشغيل ، إذا تم تقليل الضغط المطلق للسائل الذي تم ضخه إلى ضغط تبخير السائل في درجة الحرارة الحالية في المنطقة المحلية للجزء من خلال الجزء (عادة ما يكون في مكان ما وراء مدخل شفرة المكره) لسبب ما ، سيكون السائل هنا. عندما يمر السائل الذي يحتوي على عدد كبير من الفقاعات عبر منطقة الضغط العالي في المكره ، فإن السائل ذو الضغط العالي حول الفقاعات سيؤدي إلى تقلص الفقاعات بشكل حاد وينفجر. في حين أن الفقاعات تتكثف وينفجر ، فإن الجزيئات السائلة تملأ الفراغات بسرعة عالية ، وفي هذه اللحظة يتم توليد تأثير مطرقة ماء قوي ، ويصيب سطح المعدن بتردد ثنائي عالي ، ويمكن أن يصل إجهاد التأثير إلى مئات إلى الآلاف من الضغط في الغلاف الجوي في الحالات الشديدة.


إن عملية توليد فقاعات الهواء وانفجار فقاعات الهواء في مضخة المياه لتلف جزء التدفق هي عملية التجويف في مضخة المياه. بعد حدوث تجويف المضخة ، بالإضافة إلى إتلاف الأجزاء التي تصب التدفق ، فإنه سيولد أيضًا الاهتزاز والضوضاء ، ويتسبب في انخفاض الأداء الأصلي للمضخة. في الحالات الشديدة ، سيتم مقاطعة السائل في المضخة ولا يمكنه العمل بشكل طبيعي.



ثانياً ، العلاقة الأساسية بين تجويف المضخة


يتم تحديد شروط تجويف المضخة بواسطة المضخة نفسها وجهاز الشفط. لذلك ، لدراسة ظروف التجويف ، ينبغي النظر في كل من المضخة نفسها وجهاز الشفط. العلاقة الأساسية للمضخة هي: NPSHC≤NPSHR≤ [NPSH] ≤NPSHA


NPSHA = NPSH (NPSHC) －－－－－－－－ - تبدأ المضخة التجويف


npsha ＞ npshr （npshc） －－－－－－ المضخة لا تحتوي على تجويف


في الصيغة ، NPSHA - يطلق على NPSH من الجهاز أيضًا NPSH الفعال ، كلما زاد عدد NPSH ، كلما زاد احتمال تآكله ؛


NPSHR ———-PUMP NPSH ، المعروف أيضًا باسم NPSH الضروري أو انخفاض ضغط مدخل المضخة ، كلما كان أداءً أفضل في الأداء المضاد للمقاومة ؛


NPSHC ———— NPSH الحرجة ، والتي تشير إلى NPSH المقابلة لقيمة معينة من انخفاض أداء المضخة ؛


[NPSH] －－－－ يتم استخدام NPSH المسموح به لتحديد ظروف تشغيل المضخة ، عادة [NPSH] = (1.1 ～ 1.5) NPSHC.


3. تدابير لمنع التجويف:


من أجل منع التجويف ، يجب زيادة NPSHA لصنع NPSHA>NPSHR. التدابير لمنع التجويف على النحو التالي:


1. تقليل ارتفاع الشفط الهندسي الزئبق (أو زيادة ارتفاع التدفق الخلفي الهندسي) ؛


2. لتقليل فقدان الشفط HC ، حاول زيادة قطر الأنبوب ، وتقليل طول الأنبوب والمرفقين والملحقات ؛


3. منع العمل تحت تدفق كبير لفترة طويلة ؛


4. تحت نفس السرعة ومعدل التدفق ، يتم اعتماد مضخة الشفط المزدوج ، والمضخة ليست عرضة للتجويف بسبب انخفاض معدل تدفق المدخل ؛


5. عندما يحدث التجويف في المضخة ، يجب تقليل التدفق قدر الإمكان لتقليل الطاقة والسرعة ؛


6. حالة تجمع شفط المضخة لها تأثير مهم على تجويف المضخة ؛


7. بالنسبة للمضخات التي تعمل في ظل ظروف قاسية ، من أجل تجنب تلف التجويف ، يمكن استخدام المواد المقاومة للتجويف.
