It organizes fundamentals (basic mechanical parts and fluid direction indicators), then covers rotary energy converters such as hydraulic pumps and motors, energy storage elements like accumulators, and flow-direction control devices including check valves, hydraulic locks, and shut-off valves. It further lists actuator configurations, flow-rate control components, working-fluid storage and maintenance symbols (tanks, filters, coolers), and sensor/measurement symbols (pressure, temperature, level, flow, tachometer, torque).",{"@graph":14,"@context":71},[15,34,54],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/hydraulic-symbols-1basic-symbols/669055/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":48,"encodingFormat":47,"isAccessibleForFree":49,"interactionStatistic":50},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/hydraulic-symbols-1basic-symbols/669055.png","ImageObject",300,407,{"name":42,"@type":43},"jay","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-11-01",true,{"@type":51,"interactionType":52,"userInteractionCount":22},"InteractionCounter",{"@type":53},"ViewAction",{"@type":55,"mainEntity":56},"FAQPage",[57,63,67],{"name":58,"@type":59,"acceptedAnswer":60},"What do the basic hydraulic symbols represent in this reference?","Question",{"text":61,"@type":62},"They represent mechanical components, hydraulic fluid line types, flow direction, and motion characteristics such as linear or rotational movement, plus adjustability features.","Answer",{"name":64,"@type":59,"acceptedAnswer":65},"Which sections cover pumps, motors, and energy storage?",{"text":66,"@type":62},"Section 2 covers rotary energy converters including hydraulic pumps and hydraulic motors, while Section 3 focuses on energy storage using hydraulic accumulators.",{"name":68,"@type":59,"acceptedAnswer":69},"What kinds of hydraulic control and sensing symbols are included?",{"text":70,"@type":62},"Section 4 lists flow direction control symbols like check valves and hydraulic locks.
