Figure 13. The pressure decreases beser penghaslan<\/span><\/p>\n If p = 0, earning pump full Q (Q theoretical)<\/span>
\n If p> 0, the pump reduced income due to leaks and logically higher the pressure the greater the leakage.<\/span>
\n example:<\/span>
\n For a new pump, leakage 6% at p = 230 bar.<\/span>
\n Q (p = 0) = 10 l \/ min.<\/span>
\n Q (p = 230) = 9.4 l \/ min.<\/span>
\n QL = 0.6 l \/ min.<\/span>
\n So the volumetric efficiency (\u019ev) = 94%<\/span><\/p>\nFor the old pump, the leakage reaches 13% at p = 230 bar<\/span>
\n Q (p = 0) = 10 l \/ min.<\/span>
\n Q (p = 230) = 8.7 l \/ min.<\/span>
\n QL = 1.3 l \/ min.<\/span>
\n So the volumetric efficiency (\u019ev) = 87%<\/span><\/p>\n Ways of regulating \/ control in a hydraulic system arrangement of the order can be described as follows:<\/span><\/p>\n\n- Cues (Signal) input or the input element gets energy directly from generating the fluid flow (hydraulic pump) which is then forwarded to the signal processing circuit.<\/span><\/li>\n
- Cues processor or processing element that processes the input signal is logic to be forwarded to the final control element.<\/span><\/li>\n
- The control signal the end (final control element), will direct the output that is the direction of motion actuators (Working element) and this is the end result of the hydraulic system.<\/span><\/li>\n<\/ul>\n
The components of the control over the so-called valves (Valves).<\/span> According kontruksinya valves are grouped as follows:<\/span>
\n a.<\/strong><\/span> Poppet valves (Poppet Valves)<\/strong><\/span>
\n Ie when to close the valve by tapping valve (ball or Kones or disc) on the holder.<\/span> According to the type of child valves, poppet valves are classified into:<\/span>
\n – The ball valve (Ball seat valves)<\/span>
\n – Valves Kones (Cone poppet valves)<\/span>
\n – The valve disc (Disc seat valves)<\/span><\/p>\n b.<\/strong><\/span> Slide Valves (Slide valves)<\/strong><\/span>
\n – Longitudinal Slide<\/span>
\n – Slide Plate (Rotary slide valve)<\/span><\/p>\nAccording to its function valves are grouped as follows:<\/span>
\n 1).<\/span> Directional valve (Directional control valves)<\/span>
\n 2).<\/span> One-way valve (non-return valves)<\/span>
\n 3).<\/span> The pressure regulating valve (Pressure cotrol valves)<\/span>

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. …<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1406],"tags":[1513,1517,1515,1514,1522,1520,1521,1519,1516,1518],"class_list":["post-1454","post","type-post","status-publish","format-standard","hentry","category-english","tag-hydraulic-efficiency","tag-hydraulic-efficiency-definition","tag-hydraulic-efficiency-formula","tag-hydraulic-efficiency-of-a-pump","tag-hydraulic-efficiency-of-a-reaction-turbine","tag-hydraulic-efficiency-of-francis-turbine","tag-hydraulic-efficiency-of-pelton-turbine","tag-hydraulic-efficiency-of-reaction-turbine-is-the-ratio-of","tag-hydraulic-efficiency-of-turbine","tag-hydraulic-efficiency-of-turbine-definition"],"_links":{"self":[{"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/posts\/1454","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/comments?post=1454"}],"version-history":[{"count":1,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/posts\/1454\/revisions"}],"predecessor-version":[{"id":3093,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/posts\/1454\/revisions\/3093"}],"wp:attachment":[{"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/media?parent=1454"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/categories?post=1454"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.tneutron.net\/mesin\/wp-json\/wp\/v2\/tags?post=1454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
