A hydraulic cylinder that alternatively has fluid operating on both sides of its piston is referred to as a double-acting hydraulic power unit. For the retraction and extension of the pistons, it includes a port on either end that is stocked with hydraulic fluid. For applications requiring quick and predictable retractions or those requiring consistent accuracy, this kind of hydraulic cylinder is perfect. When pressurized hydraulic fluid is fed into the top port of a double-acting hydraulic power unit, the plunger retracts, causing the plunger to return to the starting position. This procedure can be carried out with precise control either extremely swiftly or very gradually. Pressurized fluid can enter and exit double-acting hydraulic cylinders through two ports. One port receives fluid, which moves the piston forward. The second port receives pressurized fluid, which pulls the piston back into the cylinder.
How Do You Convert a Single Acting Hydraulic Cylinder to Double Acting?
To make a single-acting hydraulic cylinder into a double-acting hydraulic power unit, an additional port can be added. However, only piston-equipped ingle-action hydraulic cylinders can be used for this. The type of hydraulic cylinder you have will have a direct impact on how simple or easy the conversion is. The hydraulic cylinder’s seal design may become problematic in some circumstances, and you could even need to have a special hydraulics part produced particularly for the conversion. Therefore, sometimes buying a double-functioning cylinder is less expensive and quicker.
How can I Know if My Hydraulic Cylinder Is Double Acting?
If your hydraulic cylinder has two ports where hydraulic hoses can be attached, that is usually a sign that it can be used with a double-acting hydraulic power unit. An additional hydraulic line connected to the second port produces the supplementary act single-acting acting cylinder is unable to produce. A double-acting cylinder’s first port is where the fittings for extending hydraulic hoses attach, while its second port is where the fittings for retracting hydraulic hoses attach.
How Much Does it Cost to Repair double-acting hydraulic power unit?
A double-acting hydraulic power unit ‘s repair cost will entirely depend on its type—single or double acting—the machine it is put in, and the extent of the damage. The first step is to troubleshoot hydraulic power unit issues because there are many different types of power units defects that might happen. However, to diagnose the issue, a hydraulics contractor must disassemble and examine the hydraulic power unit. This cannot be done over the phone or by email. A price for repairs or replacement will then be available from your hydraulics expert.
