Abstract

The vibration caused by the engine rotation must be within specified limits. A mechanism that is unbalanced or unstable will lead to excessive wear on ball bearings. Unbalanced condition is one of them due to a shaking force on the crankshaft which affects the wear of ball bearings as a pedestal. The problems that have been faced is the replacement of bearings after a failure caused by excessive force due to imbalance rocking rounds to get a replacement bearings before reaching failure (unreliable). The purpose of this study was to determine reliably the age of radial ball bearings in order to maintain the performance of the motor as well as the prevention of unplanned downtime nature. Prevention "malfunction" will avoid the effects on other components of diesel engines, particularly against compression disorders. Variation of residual unbalanced force large enough to cause interference with the ball bearings to reduce Mo, the rest of the unbalanced force can be siginifkan diturnkan.

Abstract

The use of the tank as well as a container or tank of liquid reserves to make use of the tank as a necessity. By using its own tank design model which is technically very possible to make the pressure in the tank is less than atmospheric pressure so that the tank will take some role pump connected in series are used for the purpose of improving high pressure. Thus the pressure in the tank is smaller than the atmospheric pressure is only generated from the process flow itself will save pump power required on the press. To prevent the air pressure in the tank exceeds the atmospheric pressure relief valve on the tank supplied air to the atmosphere. The more water into the tank, the greater the downward thrust force due to the weight of water and by the buoy to the piston in fixed position, the tank will move downward relative to the piston. The pressure in the tank due to the movement of the closed tube will follow the phenomenon of negative pressure. To get a larger volume of air or spring difleksi rate greater then the pole float should be as light as possible and frictional forces as small as possible.The goal is to produce a prototype tank that can lighten the pump working in particular on the discharge side so it can be input pump power savings. The calculations show that a high hit on the side of the press can be reduced upto 100 percent even including reducing losses on the discharge side by enlarging the capacity of the tank. Thus happen electricity savings of the power required on the discharge side of the pump to drain the water into the tank. With spring replacement inverting the inversion moment will produce a higher pressure suction force behind the rise of the spring.

Abstract

Diesel engine as the prime mover or as an auxiliary motor is still very dominant use on the ship. Diesel engines can operate with the same four-stroke cycle gasoline engine with: intake, compression, combustion and exhaust. One advantage of the diesel engine is the fuel consumption is better than gasoline engines due to lower pumping loss and high compression ratio. Conversely, there are drawbacks, such as vibration and noise during operation and large this state will increase along with the deterioration of the quality of lubricants. To detect thecondition of lubricants can be done by measuring the viscosity and total base number (TBN) .. Nevertheless, every machine has different characteristics from each other, so as to know the condition of engine lubricant is casuistry anyway. In this case, replacement of engine lubricant boat with linearity approach is on a machine that has a high reliability aimed at determining the condition of engine lubricant according to the hours of operation.
