Viscometer adalah alat untuk mengukur besar viskositas suatu cairan. Ada beberapa komponen terkait viscometer antara lain : A. Ball Viscometer atau Falling sphere viscometer. Besar viskositas kenematik adalah kecepatan bola jatuh setinggi h dibagi dengan berat jenis cairan yang sedang diukur. (lihat gambar 1) Gambar 1. Falling sphere viscometer Gambar 2. Capilary viscometer B. Viscosity margins. Maksud dari viscosity margins ...

From the name can be known the value of accuracy of this tool is in units of microns = 0.01 mm. So when compared with a ruler sliding micrometer accuracy memilliki doubled compared with a sliding crossbar 0,02mm accuracy, and thoroughness memilliki tenfold compared with accuracy of 0.1 mm sliding crossbar. So for the measurement of precision parts required using ...

On Hydraulic modules will discuss a variety of fixed displacement pumps. a. Pump gears (External Gear Pump) External gear pump consists of main parts:  – pump house  – A pair of outer gears mesh precision in the pump housing  – first mover (prime mover) which is coupled to the shaft axis gear driver. Of rotation of a ...

Yang dimaksud dengan efisiensi ialah perbandingan antara output dan input dan dinyatakan dalam persen ( % ). Terjadinya perbedaan antara output dan input dikarenakan adanya kerugian-kerugian diantaranya terjadinya kebocoran di dalam pompa sehingga akan mengurangi volume output. Secara keseluruhan, kebocran dapat terjadi pada pompa hidrolik, katup-katup, aktuator dan pada setiap konektor. Sehingga dalam hal ini perbandingan antara volume cairan hidrolik ...

When working around a hydraulic circuit, the safety of yourself and others is the first consideration. The recommendations suggested in this section are common precautions that are always observed when working on a hydraulic system. 1. Always lower the hydraulic work unit to the ground before leaving the vehicle. 2. Park the engine vehicle on flat ground and use the ...

What is meant by efficiency is the ratio between output and input and is expressed in percent (%). The difference between output and input due to the losses include leaks in the pump so that it will reduce the volume of output. Overall, kebocran can occur in hydraulic pumps, valves, actuators, and on each connector. So in this case the ...
