Product DescriptionProduct DescriptionWhat's the plunger cylinder?A plunger cylinder is a hydraulic actuator that uses hydraulic oil pressure to drive a plunger in linear reciprocating motion, outputting force or displacement. Its core structure includes a cylinder barrel, plunger, guide sleeve and sealing devices. The plunger, typically a solid cylindrical rod, doesn't directly contact the cylinder barrel's inner wall but maintains stability via the guide sleeve. During operation, pressure oil enters the chamber on one side of the plunger in the cylinder, pushing it to extend. The plunger's return usually relies on external forces (e.g., gravity, spring force or reaction from other loads), making it mostly unidirectional. Compared to piston cylinders, its cylinder barrel inner wall needs no precision machining, lowering manufacturing costs. With good plunger rigidity, it suits large axial forces and is used in long-stroke, heavy-load scenarios like metallurgical equipment, mining machinery and presses.ComparisonPlunger CylinderPiston CylinderBasic AttributePlunger - cylinder non - contact, unidirectional, external - force returnPiston - cylinder contact, bidirectional, oil - controlled returnPerformanceHigh - pressure (over 30MPa), large thrust, for long - stroke/heavy loadPressure 16 - 25MPa, moderate thrust, for regular load/fast responseStructureSimple cylinder, high - precision plunger, guide - sleeve sealedPrecision cylinder, piston with seals, complex sealingCostLow cylinder cost, extra for plunger finishingCost varies with materials/precision; high - end needs raise costScenariosMetallurgy, mines, long - stroke pressesServe industrial fields, split by load/needs, support hydraulicsMaintenanceCheck guide sleeve, plunger, return partsReplace seals, monitor wear for sealing/stabilitySpecificationPlunger Cylinder Manufacturing:1. Forging & Precision Machining: High-strength steel forged, CNC - machined to tight tolerances (ensures heavy-load resistance). 2. Surface Treatment: Chrome plating/polishing for low friction, long wear life (suits harsh environments like marine/mining). 3. Sealing & Testing: Custom seals matched to pressure/temperature; 100% pressure tested (guarantees no leakage, reliable operation).
