Abstract

Dusun Ketos and Dusun Cabe is 2 (two) of 7 (seven) Dusun in Kulon Wonodadi Ngadirojo Pacitan, EastJava. The problems faced by the community, especially for Ketos Dusun and Dusun Cabe whose territory the formof hills and rocks are prone / difficulty of clean water, clean water to meet the needs of the people using water fromsprings and rainwater. In the dry season, water from springs debitnya reduced, so that less water needs in thevillage. Only water can not be drained using gravity because it is under the township residents located on the hill - ahill at an altitude of 750 m above sea level. The approach offered to solve the problem is by making a catchmentbasin, hydraulic ram and tank water divider.The effectiveness of the performance of hydraulic ram is influenced by several parameters, among others: the lengthof the inlet pipe, inlet pipe diameter, high penagkap tub of water, and heavy exhaust valve. This study aims toobserve and analyze the effect of altitude penagkap tub of water and a long inlet pipe to the pump head on thehydraulic ram. The research method through designing hydraulic ram and analyzing the catchment basin height of2.9 m, 3.2 m and 3.5 m and a length of inlet pipe 18 m, 24 m and 30 m. Tests carried out in the river, precisely inDusun and Dusun Ketos Cabe, Pacitan.Based on the research and analysis it can be concluded that by using the height of basin catchment 3.5 m and 30 mlength of pipe entry could generate more volume and maximum pressure compared with other tests and can producewater flow of up to 6.7 L / min at pump head 173 m with a vertical condition.So the higher the basin catchment (H), the greater the discharge of the hydraulic ram and the pressure generated inthe intake also getting bigger, while for long inlet pipe (L), the length of the pipe entering the greater the volumeand pressure of entering into Conductor flowing through the valve body hidram, because the water is very largeimpulse will open the waste valve and the valve closed waste arrived - arrived to make the flow greater impetus.This is because water is the greatest moment of the collision on H 3.5 m and 30 m L it affect the discharge resultsand the hydraulic ram pump head.Keywords: hydraulic ram, high penagkap tub of water, the length of the pipe entrance

Abstract

Hamlet Ketos and hamlets Cabe is 2 (two) of 7 (seven) hamlet in Wonodadi Kulon, Ngadirojo Pacitan, the problems faced by the community, especially for Hamlet Ketos and hamlets pepper the area of hills and rocks areprone / difficulty getting water net. The approach offered to solve the problem is by making a catchment basin,hydraulic ram and tank water divider.Hydraulic ram works on the principle of water hammer. When the fluid flow is stopped suddenly it changes themomentum of the fluid future will increase the pressure suddenly. Increased pressure is used to lift some of thewater to higher ground. Then designed hydraulic ram which uses the potential energy of the water as a vehicle. Indesigning the authors use the pump inlet pipe length variation of 18 meters, 24 meters and 30 meters and a diameterof the valve opening is full (0.1 meters), 0.08 meters and 0.065 meters. Tests carried out in the river, precisely inHamlet and Hamlet Ketos Cabe, Pacitan.It can be concluded at this test that by using a long inlet pipe diameter of 30 meters and full valve opening is 0.1meters and the discharge pump head has more leverage than other tests, namely the pump head 173 m and waterdischarge (output) generated amounted to 6.68 L / min. So the longer the pipe entrance (L), the higher the pressuredihasilakan, as well as thelarger the diameter of the valve opening, the greater the pressure acting on the hydraulicram, because the greater the time and speed, the momentum was also greater, so the impulse weight the exhaustvalve is closed suddenly make a greater boost the flow exceeds the static pressure inlet pipe, and it affects the pumphead on the hydraulic ramKeywords: hydraulic ram, a long inlet pipe, the diameter of the valve opening

Abstract

Viscosity of a liquid is one of the characteristics that determine the amount of fluid resistance to shearforce, the viscosity occurs mainly due to the interaction between the molecules of the fluid in the hydraulic system.This viscosity depends on temperature changes, therefore, use the proper oil viscosity especially those that do notchange much with temperature is needed once the hydraulic system in order to get a good performance. Thehydraulic system is a technology that utilizes liquid, usually oil, to perform an inline movement or rotation. Thissystem works on the principle of Pascal, ie if a liquid subjected to pressure, the pressure will propagate in alldirections with no increase or decrease its power. Hydraulic Trainner machine is a device that works usinghydraulic system applications , to move the tool cylinders using a fluid or oil of type SAE 10 , SAE 30 and so on .This thesis aims to analyze the influence of oil viscosity and oil temperature of the hydraulic system performanceand showed that oil SAE 30 turned out to have a better performance approximately 18 % of the oil SAE 30. It can beconcluded that for Trainner hydraulic machine is better to use oil SAE 10 oil than SAE 30 . Keyword : viscosity, temperature, hydraulic system, SAE 10 oil and SAE 30 oil.

Abstract

Nowadays, we find several places in towns which hit by floods, it happen because some things, for example water duct which is gagged because of a bunch of rubbish, a small duct just make the water overload, and a shallowduct because of mud sediment. Because of the problem above, there is an idea to design a process to make a simpletool named piping installation on the pump vacuum of mud. This research method is used to analyze the influence ofmud viscosity and diameter variation of mud suction pipe to the flow capacity of mud vacuum pump machine. Eachof mud viscosity diameter 1,1225 N.s/m², 1,1849 N.s/m². And diameter variable of mud pump vacuum 0,0127m,0,0191m, 0,0254m. The examiner tries to do this observation in each variable for three times. From the statementabove, it can assume that the higher value of mud viscosity the lower of pipeline capacity. In each higher viscosity(η) = 1,3003 N.s/m², in diameter of mud pump vacuum 0,0127m, Q = 0,0002886 m³/s, in diameter of mud pumpvacuum 0,0191m, Qoutout = 0,0002975 m³/s, in diameter of mud pump vacuum 0,0254m, Qout = 0,0003667 m³/s.Meanwhile, in trial diameter variation of mud suction pipe, the bigger diameter of mud suction pipe the higher ofpipeline capacity. So the higher of pipeline capacity is happen in diameter of mud suction pipe 0,0254m with Q =0,0003984 m³/s. The higher pipeline viscosity (Q) is happen in diameter of mud suction pipe 0,0254m which is(Qin) = 0,0001784 m³/s and resulting (Q) 0,0003984 m³/s. outinKeywords: Mud pump vacuum, diameter variation of mud suction pipe.
