Problems solved by technology

During the stuffing process, the skin bag is prone to folding and twisting, and the skin bag cannot be filled to the bottom, so it is often necessary to repeatedly pull out and stuff in. The rubber skin is repeatedly squeezed and rubbed by the tank top, which is easy to produce pull marks
After inflating, the leather bag cannot be completely straightened, and the stretch marks, folded and twisted parts are prone to damage, which greatly shortens the service life of the leather bag

Embodiment 1

[0026] Embodiment 1: see figure 1, an accumulator bladder online replacement device, the replacement device includes a pumping and charging device, an accumulator assembly, a guide rod, a wrapping and a rope, the pumping and charging device is arranged on the accumulator assembly, and the guide rod is used for Guide radially through the rope; the pumping and inflating device includes a body, a handle 101, a pressure gauge 102, a hose 103, a thimble 104 and a connecting block 105, the handle is arranged above the body, and the pressure gauge 102 is arranged on one side of the body, The hose 103 is set on the other side of the main body, and the thimble 104 and the connecting block 105 are set under the main body; the rotating handle 101 drives the thimble 104 to move up and down in the axial direction, and opens or closes the bladder check valve 2 to realize air extraction or inflation to the bladder The pressure gauge 102 is a pressure gauge with a negative pressure display. W...

Embodiment 2

[0028] Example 2: see figure 1 , an online replacement method for an accumulator bladder, the replacement method comprising the following steps: 1) a step of removing the bladder; 2) a step of installing the bladder. The skin bag removal step in step 1) is as follows: 11), first unscrew the skin bag protective cap 1 and other accessories, and follow the figure 2 As shown, use the pumping device to connect with the leather bag, push the rotary handle 101 into the thimble 104 to open the one-way valve 2 in the accumulator, and release nitrogen; then remove the leather bag fixing nut 3, pressure ring 4, and distance ring 9. Press down into the skin bag 6, and fold the split ring 8 out; 12) Fold the skin bag 6 out, fold and pull it out, and use the pumping device to connect with the skin bag to ensure that there will be no residual air in the skin bag 6, especially The damage point is in the upper part of the skin bag. When the skin bag 6 is pulled out halfway, the residual air ...

Description

technical field [0001] The invention relates to an on-line replacement device for an accumulator bladder, which belongs to a method for replacing an accumulator bladder for a hydraulic system, and is especially suitable for on-line replacement of a top-mounted accumulator bladder. Background technique [0002] In the hydraulic system, as an auxiliary component, it mainly plays the role of storing energy, absorbing hydraulic shock, eliminating pulsation and recovering energy. In particular, large hydraulic systems generally use accumulators and pressure relays in combination as auxiliary energy. There are also hydraulic systems for To absorb system pulsation, an accumulator is used at the outlet of the hydraulic pump to effectively attenuate the pulsation, so that the hydraulic pump can work smoothly. For some occasions where the hydraulic valve closes rapidly and the load changes drastically, the accumulator can also be used to alleviate the hydraulic shock and protect the hy...
