Identifikasi Getaran Mekanis Thrust Bearing Pompa Sulzer Bingham yang Mengalami Kegagalan
نویسندگان
چکیده
Thrust bearing yang berfungsi mendukung gaya-gaya terjadi pada  pompa Sulzer Bingham Type 8 x 10 13 MSD – D 3 Stage akan mengalami kerusakan berakibat kegagalan pula komponen lain. Perubahan sifat mekanik disebabkan oleh kondisi pembebanan tidak baik, seperti terjadinya unbalanced dan poros sesumbu (missalignment) menimbulakan getaran.Metode diterapkan dalam pengujian melalui pendekatan analisis thrust 7310 BECBM. Data BECBM didapatkan frekuensi vibrasi, intensitas kebisingan dilakukan pengolahan data menggunakan vibrasi bentuk domain bantuan software MATLAB.Data pengamatan 0 1225 jam menunjukkan indikasi ditemukan 1663 jam. arah horizontal unbalanced. Spektrum terhadap vertikal ditunjukkan Gambar 7. fenomena bent shaft atau ketidaklurusan sumbu poros. Frekuensi lebih tinggi dibandingkan aksial. Komponen cage memiliki kekerasan rendah lainnya sehingga cepat kerusakan.

Frictional Characteristics of Thrust Bearing in Scroll Compressor
This paper presents frictional characteristics of thrust bearing in scroll compressor. The coefficient of friction in thrust bearing was measured by both elemental friction test and loss classification based on the performance test of actual scroll compressor, and investigated frictional characteristics focusing on the behavior of sliding portion which affects the generation of oil film by expe...
متن کاملDevelopment of Orifice-type Aerostatic Thrust Bearing for Precision Machine
Air bearings are used in precision machines and measurement equipments for recently years. Unlike conventional ball or roll bearings, there is no physical contact between the sliding surfaces and the moving surface. Therefore, the structure with air bearings can glide smoothly on the other surface to avoid generating the small particles from the friction contact and also minimize the control ef...
متن کاملA Thermal Elastohydrodynamic Lubricated Thrust Bearing Contact Model
A fully-coupled thermoelastic model for a fixed pad thrust bearing has been developed. Pressure, film thickness and three-dimensional temperature profiles were obtained by simultaneously solving the Reynolds, film thickness, energy and force balance equations using a combined finite difference and finite element method. The elastic deformation due to the pressure and the thermal distortion due ...
متن کاملNote: Radial-thrust combo metal mesh foil bearing for microturbomachinery.
This Note proposes a novel radial-thrust combo metal mesh foil bearing (MMFB). Although MMFBs have advantages such as higher stiffness and damping over conventional air foil bearings, studies related to MMFBs have been limited to radial MMFBs. The novel combo MMFB is composed of a radial top foil, thrust top foils, and a ring-shaped metal mesh damper--fabricated by compressing a copper wire mes...
متن کاملμ Control of a High Speed Spindle Thrust Magnetic Bearing
Experimental results demonstrate that μ synthesis provides an excellent tool for increasing the dynamic stiffness of thrust magnetic thrust bearings. Accurate system modeling and appropriate uncertainty descriptions are critical to obtaining such results and are described in detail. Both complex μ and mixed μ synthesis were used to design controllers. The performance of the μ controllers is com...
