  1. 1. Introduction: A pump is a device used to move liquids. A pump moves liquids from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system ‫الضغط‬ ‫منطقة‬ ‫الى‬ ‫المنخفض‬ ‫الضغط‬ ‫منطقة‬ ‫من‬ ‫السائل‬ ‫تحريك‬ ‫فى‬ ‫تستخدم‬ ‫مضخة‬ ‫عن‬ ‫عبارة‬ ‫هى‬‫المر‬‫تفع‬ .‫وتتغلب‬‫فى‬ ‫الحركة‬ ‫طاقة‬ ‫زيادة‬ ‫طريق‬ ‫عن‬ ‫الضغط‬ ‫فرق‬ ‫على‬‫النظام‬.

  4. 4. 1)- Roto-dynamic pumps (centrifugal pumps) 1.1)-Working Mechanism of a Centrifugal Pump. A centrifugal pump is one of the simplest pieces of equipment in any process Plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. ‫االساسى‬ ‫المحرك‬ ‫من‬ ‫الناتجة‬ ‫الطاقة‬ ‫بتحويل‬ ‫تقوم‬(a electric motor or turbine)‫حركية‬ ‫طاقة‬ ‫الى‬ (kinetic energy)‫السائل‬ ‫بضغط‬ ‫تقوم‬ ‫ضغط‬ ‫طاقة‬ ‫الى‬ ‫تتحول‬ ‫وبالتالى‬ ‫السرعة‬ ‫زيادة‬ ‫طريق‬ ‫عن‬.

  7. 7. 1.2.1)-Rotating Components in Pump 1)-Impeller. The impeller of the centrifugal pump converts the mechanical rotation to the velocity of the liquid. The impeller acts as the spinning wheel in the pump. ‫للسائل‬ ‫سرعة‬ ‫زيادة‬ ‫الى‬ ‫االساسى‬ ‫المحرك‬ ‫من‬ ‫الناتجة‬ ‫الميكانيكية‬ ‫الحركة‬ ‫تحويل‬ ‫على‬ ‫يعمل‬ They are often classified in many ways Based on mechanical construction. There are three types of construction seen in an impeller. These are based on the presence or absence of the impeller covers and shrouds. 1. Closed 2. Semi-open 3. open

  14. 14. 2)Pump casing Casings are generally of two types: volute and circular. The impellers are fitted inside the casings A volute: is a curved funnel increasing in area to the discharge port as shown. As the area of the cross-section increases, the volute reduces the speed of the liquid and increases the pressure of the liquid. ‫وعاء‬ ‫عن‬ ‫عبارة‬ ‫هو‬(‫لل‬ ‫مبيت‬ ‫مساراو‬impeller)‫ويزيد‬ ‫السرعة‬ ‫لتقل‬ ‫الطلمبة‬ ‫طرد‬ ‫عند‬ ‫مساحته‬ ‫يزيد‬‫الضغ‬‫ط‬ (‫التصميم‬ ‫ذلك‬ ‫من‬ ‫الغرض‬) Pump Casing

  16. 16. 3)-Wearing rings The impeller is a rotating component and it is housed within the pump casing. To prevent frictional contact, a gap between these two parts is essential ‫الطلمبه‬ ‫فى‬ ‫الثابت‬ ‫والجزء‬ ‫المتحرك‬ ‫الجزء‬ ‫بين‬ ‫يوضع‬(impeller and casing)‫جدا‬ ‫بسيط‬ ‫خلوص‬ ‫وجود‬ ‫من‬ ‫البد‬ ‫بين‬(impeller and casing)‫الطلمب‬ ‫كفاءه‬ ‫تقل‬ ‫الخلوص‬ ‫هذا‬ ‫زيادة‬ ‫وعند‬ ‫لهما‬ ‫وتاكل‬ ‫احتكاك‬ ‫يحدث‬ ‫ال‬ ‫حتى‬‫ة‬ ‫على‬ ‫والمحافظه‬ ‫الخلوص‬ ‫تلك‬ ‫على‬ ‫المحافظه‬ ‫يجب‬ ‫ولذلك‬(impeller and casing)‫مواد‬ ‫من‬ ‫مصنوعتن‬ ‫النهما‬ ‫يوضع‬ ‫لذلك‬ ‫خاصة‬wear ring Wear ring different type Location of wear ring
  17. 17. 4)-Shaft The pump rotor assembly consists of the shaft, impeller, sleeves, seals (rotating Element), bearings or bearing surfaces, and coupling halves. The shaft, however, is the Key element of the rotor. The basic purpose of a centrifugal pump shaft is to transmit the torque. ‫االساسى‬ ‫المحرك‬ ‫من‬ ‫العزم‬ ‫بنقل‬ ‫يقوم‬ ‫انه‬ ‫حيث‬ ‫للطلمبة‬ ‫االساسى‬ ‫المحرك‬ ‫هو‬ ‫العمود‬ ‫يعتبر‬(motor. ) Shaft
  18. 18. 5) Stuffing boxes. The stuffing box is a chamber or a housing that serves to seal the shaft where it passes Through the pump casing. and we can used Packing ring or Mechanical seal depending on application. ‫العمود‬ ‫بين‬ ‫حجرة‬ ‫عن‬ ‫عبارة‬ ‫هو‬casing‫منع‬ ‫على‬ ‫تساعد‬‫تسريب‬‫السائل‬ Stuffing box Bearing house
  19. 19. 6)-Bearing support This is based on the location of the bearings supporting the rotor. If the rotor is supported in the form of a cantilever ,it is called as an Overhung type of pump. When the impellers on the rotor are supported with bearings on either side, the pump is called as an in-between bearings pump. ‫وجود‬ ‫حسب‬ ‫على‬ ‫التصنيف‬ ‫تلك‬ ‫يعتمد‬bearing‫ال‬ ‫لوجود‬ ‫بالنسبة‬rotor Overhung In between bearing pump Bearing Bearing

  28. 28. Rotary pump (Gear Pump) Gear pumps belong to a positive displacement rotary group, and are made by enclosing two or more gears in a close-fitting housing. A driver turns a shaft connected to one of the gears, causing it to rotate This gear drives the other gear through the meshing of the teeth of the two gears. ‫السائ‬ ‫ويمرو‬ ‫للتروس‬ ‫تعشيق‬ ‫يحدث‬ ‫تحريكة‬ ‫وعند‬ ‫االساسى‬ ‫باامحرك‬ ‫متصل‬ ‫احداهما‬ ‫تروس‬ ‫من‬ ‫تتكون‬‫بين‬ ‫ل‬ ‫و‬ ‫الترس‬ ‫أسنان‬casing
