Product description

Function: The MP-Series of hydraulic pressure intensifiers are reciprocating, and will automatically increase a supplied pressure to a higher end pressure. Fig. 1 in the attached brochure shows the basic principle of the intensifiers, consisting of a piston arrangement and a Piston Control Valve, PCV. The position of the pistons will at the end of every stroke prompt a signal S to the PCV, which makes this change position, ensuring the pistons are moving in the opposite direction. This cycle will continue until the end pressure has been reached. At this point the system stop, and will now only move to maintain the end pressure. The Cycle: When a hydraulic fluid is supplied to the P-connection of the intensifier and the T-connection is connected to tank, the oil will be directed through the check valves CV1 and CV2 to the high pressure connection HP. If the internal pilot operated check valve POV is incorporated the oil will go straight to the HP connection. In this situation all the flow supplied goes to the high pressure side ensuring a fast filling of the system. Once pump pressure has been reached, the intensifier pistons will deliver the flow to the high pressure side, and continue to do so until the required end pressure has been reached. The pistons then stop, and will only move to make up for a pressure loss due to leakage or consumption. A general flow curve showing how the intensifier works is shown in Fig.2 in the brochure. For evacuating the high pressure side the internal POV is used. This valve is opened by directing the supplied pressure to the T-port and connecting the P-port to tank. This makes the POV open, and the oil from the high pressure side can flow directly back to tank.
