Manual pipe bender hydraulic parts manual hydraulic pipe bender SWG-4D factory production speed of a hand pump and set the overload relief agencies and the oil filter, manual hydraulic pipe bender with a reasonable structure, light weight, small size, long service life, ideal for construction, chemical, plumbing, oil, coal and other departments manual bending tools SWG-4D manual hydraulic pipe bender SWG-4D manual hydraulic bending machine main technical parameters Model SWG-2A maximum working pressure 44Mpa maximum working stroke 250 mm bending angle is Π / 2 ≤ a <Π radius of curvature of 4D hydraulic oil grade N15 tubing OD Series 21.3 × 2.75 26.7 × 2.75 33.5 × 3.25 42 × 3.25 48 × 3.5 60 × 3.5 Machine weight 60kg Overall size 76 × 38 × 23cm to use l Tighten the switch to manual hydraulic pipe bender, wheel bearings, and dies with the curved workpiece contact area coated with grease. 2, according to the bend pipe size, select the bending mode, mounted on top of the piston rod, the size of the two supporting wheel slot facing the bending mode, pay particular attention to supporting round should be placed on the side of the wing surface corresponding size hole, "maximum specification outermost hole and so on. avoid the location of the two support wheels asymmetry, causing damage to the mold and parts. workpiece will be put away on the upper wing cover make curved molded to the first fast pump workpiece pieces, and then the slow pump workpiece pressure to the desired angle, bend after open off the working piston will automatically reset, and open on the wing, remove the workpiece., Note: 1, the use of manual hydraulic pipe bender before the first check the oil in the fuel tank of the adequacy of such deficiencies should fill work before switching - scheduled to be shut; pressure not hit on the fuel drain plug loosen, so that the fuel tank ventilation. 3, the elbow the outside diameter of the material must fit with the groove of the bending mode, otherwise the workpiece will produce clashing phenomenon or to split up the mold. 4, welded pipe welds in the bend is the outside or being inside of the bending process two support wheels rotating workpiece slide in the groove of the bearing wheels, such as the single-sided fixed should stop operating manual hydraulic pipe bender peacetime for equipment cleaning and maintenance work, refueling To clean - scheduled to go through the more than 80 mesh strainer filter, oil filter device 6, manual hydraulic pipe bender No. 15 machine oil should be cleaned regularly. wearing parts for user-friendly maintenance manual hydraulic pipe bender wearing seals placed in the spare parts bag the oil valve. possible failures and Remedy: Fault Cause Remedy 1, piston rod stretched out after a certain length of shaking the handle rod stretched it out a shrink. refueling Songane drain plug not loosen the oil drain plug the pump mouth is not sealed the oil valve Ball Park, the entire oil garbage, you should replace it with clean oil, replace the steel ball. 2, large, small pump piston rod at the oil leaking seals damaged spare parts bag seals put on 3 Tighten the pressure ring Remove the stopper is too loose screws and switch the switch at the oil leakage switch lap 4, the top peak of the staff out of weakness, not work. switch Ball seal no bad switch top the top firmly Ball or falling steel ball exchange Ball screw tight switch, such as non-steel ball, should be added to the steel ball ejector top oil spill piston rod top ring damage replace the 14 × 2.4 O-ring (not included), large, small pump to fill lateral loads such as: bend over the workpiece with garbage or insufficient oil Unscrew 12 serial parts, and fill up with gasoline to clean mesh. 7, the the mold mounting holes split mold items out the filter inside the filter on location not put then bend is to check the wheel position of the two supporting symmetric, support wheel and the workpiece fit oiled, put a positive second bent position. 8, picked up the pump, also known to take the pump back to pump out the oil valve steel Lang head knocking the ball can not be normal reset action rod (15) extends, so there is pressure on the piston pump, the handle on the seat (14) several times to reset the valve ball Contact: Jiangjing Li phone: 15653732939 Tel 0537 -2998821 Fax :0537-2228358 QQ: 1970907860
