WIDODO, HERMAWAN SETYO ( 2111 038 016 )




ABSTRAK

Mechanical seal adalah suatu sealing device alat pengeblok cairan salah satu dari dinamik seal yang berfungsi untuk menghindari mencegah kebocoran pada stuffing box pompa centrifugal. Mechanical seal tersusun dari 2 buah sealface yang saling bergesekan dimana sealface pertama melekat pada shaft pompa poros pompa yang berputar dan sealface kedua diam melekat ikut pada dinding statis casing pompa rumah pompa. Mechanical seal sangat dibutuhkan oleh pompa sentrifugal terutama pada industri besar contohnya pada industri pembangkitan PT. PJB. UP Gresik PLTU Unit 3-4 karena hanya sealing device dengan tipe mechanical seal yang cocok dan mampu menahan tekanan serta temperatur tinggi dari Boiler Feed Pump BFP PLTU Unit 3-4. Namun mechanical seal ini masih mempunyai banyak kelemahan yakni sangat mudah bocor dan mudah rusak dikarenakan mechanical seal tergantung oleh lifetime umur guna alat pendek yang hanya mampu bertahan sampai 3 tahun. Dari hasil pengamatan yang dilakukan dapat disimpulkan bahwa kondisi mechanical seal 4C di PT. PJB UP Gresik Unit 3-4 berada dalam kondisi sangat buruk dan harus segera dilakukan perbaikan. Sebab dengan pembanding mechanical seal di Boiler Feed Pump 4A yang telah dilakukan perbaikan performa dari Boiler Feed Pump 4C sangat jauh menurun. Penurunan performa dari Boiler Feed Pump dapat berasal dari berbagai hal diantaranya yakni adanya kerusakan dibagian mechanical seal sisi seal face contact face yang telah aus akibat gesekan contak langsung dengan seal face lain dimungkinkan juga dapat disebabkan oleh lifetime dari carbon sealface itu sendiri dan juga korosi dari mechanical serta hal hal lain yang dapat merusak mechanical seal.


ABSTRACT

Mechanical Seal is a sealing device tool of fluid blocked which is one of the dynamic seal that serves to prevent avoid leakage a centrifugal pump stuffing box which is composed of between 2 seal face namely seal face attached to the pump shaft rotates with silent seal face attached to the wall of the pump house static. Mechanical Seals are needed by a centrifugal pump especially in large industrial example in PT generation industry. PJB. UP Gresik Steam Power Plant Units 3-4 because the only type of mechanical seals with seals that fit and able to withstand high pressures and temperatures that services by Boiler Feed Pump BFP Power Plant Units 3-4. Mechanical seal but still have a lot of weaknesses which are very easily leak and can easily be damaged due to mechanical seals hanging by a lifetime to age tool which is short and only reaches 3 years. From the observations made it can be concluded that the condition of the mechanical seal PT 4C. PJB UP Gresik Units 3-4 are in very bad condition and need immediate repair. For the comparison of mechanical seals in Boiler Feed Pump 4A that improvements have been made the performance of Boiler Feed Pump 4C is very much decreased. The decline in the performance of Boiler Feed Pump can come from many things including the existence of the damage section side seal mechanical seal face contact face that has been worn due to friction contact directly with the other seal face can also be caused by the lifetime of carbon seal face itself and also corrosion of mechanical and things - other things that can damage the mechanical seal.
