Product Description Electric-powered Hydraulic Tube ExpanderThis Electric powered hydraulic tube expander is a special equipment used to expansion jointing tubes and tube sheet in the manufacture of boilers, heat exchangers, condensers, high pressure heaters and other equipment. The equipment can reliably expand heat exchange tubes of various specifications and materials, and is especially suitable for the expansion of thick tube sheets and large-diameter tube heat exchangers.Working PrincipleThis equipment adopts hydraulic expansion joint method. The electric motor in the hydraulic power pack drives the hydraulic pump to pressurize the water or hydraulic oil, then the high-pressure hydraulic pressure is delivered to the expanding-handle, and finally reaches the expanding-rob. The expanding-rob is expanded under the drive of high hydraulic pressure to complete expansion-joint.FeaturesHydraulic expansion joint, there is no oil pollution at the expansion joint, and the welding after expansion is not affectedAutomatic water replenishment, automatic coolingPLC control, the outlet pressure can be set accuratelyMaximum outlet pressure up to 350MpaPressure-holding function, the pressure-holding time can be selected arbitrarily from 0.1 to 50 secondsElectrical protection device built-inExpanding-handle weight is 0.8Kg only, easy to operateIt can work continuously, one person can continuously expand and connect, and can expand 6-8 tubes per minuteCompositionThe Hydraulic tube expander is composed of hydraulic control system, pressure amplification system and hydraulic expansion-joint control system.ComponentsThe Hydraulic tube expanding machine includes three main components:Hydraulic power pack: generate and output high hydraulic pressureExpanding-handleHydraulic expanding-rod: The one-piece hydraulic expanding-rod is composed of high-strength alloy steel core rod and high-pressure resistant elastic rubber. The integrated design can withstand ultra-high pressure without using seals. It is easy to use and has high work efficiency. It uses the radial pressure generated by the high-pressure hydraulic pressure input from the hydraulic power pack to the elastic rubber body to expand tubes on the tube sheet, so that the pipe material undergoes plastic deformation, so as to realize the expansion joint between tubes and the tube sheet.Maximum outlet pressure350MpaExpanding handle weight0.8KgTube's outer diameter≥5mmHydraulic power pack dimension126x96x150cmTube sheet's thickness≥6mmHydraulic power pack weight450Kgshell of tube0.2 - 18 mmMotor power5.5KWExpansion length6 - 4600 mmTotal power6.5KWConnector of expanding-robM10X1 (mm)Hydraulic pump flow rate10L/minTube sheet holes roughness6.3μmLiquid tank100LExpansion-joint mediumwater or oilElectric power380VExpansion-joint efficiency5-8 tubes/minute Control modePLC with touch screenOperation Instructions1. Turn on "Power" button.2. Set pressure value in touch screen.3. Evacuate the air in the high-pressure hose and the expanding-rod: 4. The operation method of the expanding- rod: insert expanding-rod into tube until the expansion position, press the switch on the expanding-handle and then release it. At this time, the "boost" indicator light is on, and the machine starts to automatically control the expansion process; When the pressure reaches your preset pressure value, the boosting stops, and it automatically enters the depressurizing state. At this time, the "depressurization" indicator lights up; after the depressurization is completed, the expansion rod can be pulled out. Then expand the next tube, and so on.Workplace Real Shot
