P-30 Hydraulic Press for Cylinder Liners - 30 Ton Capacity

The cylinder liner machine is used to extract worn or damaged liners from diesel engine blocks and install new liners. It's essential in machine shops for repairing heavy-duty engines, such as trucks, tractors and industrial equipment. The P-30 Hydraulic Press performs this operation with 30 tons of force, ensuring the liner is removed or installed without damaging the engine block.

The P-30 press has maximum capacity of 30 tons with piston stroke of 11.8 inches (300 mm). The work table measures 19.7 x 59 inches (500 x 1500 mm), supporting diesel engine blocks of various sizes. The lateral clearance is 26.8 inches (680 mm) and maximum table-to-shaft distance is 22.4 inches (570 mm). Features 5 hp electric motor with piston speed of 30.7 IPM (780 mm/min), providing power and precision for professional workshops.

The P-30 works with small to medium diesel engine blocks, including light and medium truck engines, agricultural tractors, industrial generators and construction equipment. With a 19.7 x 59 inch (500 x 1500 mm) table and 30-ton capacity, it handles most diesel engines used in commercial and industrial applications. The 11.8-inch (300 mm) stroke allows working with liners of different heights.

Hydraulic press offers constant and controlled force of 30 tons, while manual extractors depend on human strength and leverage, limiting capacity. The P-30 has working speed of 30.7 IPM (780 mm/min), being much faster than manual methods. Hydraulic presses also reduce risk of damaging the block, as they apply uniform force, unlike manual extractors that can generate uneven stresses.

The process starts by positioning the block on the press table and aligning the extractor over the liner. The hydraulic system applies gradual and constant force through the piston, pulling the liner out of the cylinder. The P-30 controls speed at 30.7 IPM (780 mm/min), avoiding impacts that can crack the block. For installation, the process is reversed: the new liner is pressed into the cylinder with the same precision.

A well-maintained P-30 press can last decades in professional use. Basic maintenance includes regular hydraulic oil changes, filter cleaning and system seal inspection. The 5 hp electric motor is robust and needs only periodic bearing lubrication. Checking table alignment and hydraulic pressure calibration annually ensures precision and extends machine service life.
