The study of methods for combined processing of deep holes

platforms, cranes, manipulators, concrete pumps, loaders, compressors, dump trucks. In principle, hydraulic cylinders are similar to pneumatic cylinders, however, the driving force in the hydraulic cylinder is a liquid, such as water or oil. Wear resistance is the main requirement for the inner surface of the hydraulic cylinder.

Pump Types Guide - Find the right pump for the job

Pump is typically a diaphragm style, though older designs are plunger type. Diaphragm is driven by solenoid, mechanical actuation, or hydraulic actuation. Pump includes inlet and outlet check valves. Normally contains stroke length adjustment to vary flow rate, and some pumps can also control flow rate with speed control.

Design & Fabrication of Concrete Slab Lifting Device

In essence, slab jacking attempts to lift a sunken concrete slab by pumping a grout through the concrete, effectively pushing it up from below. The process is also commonly referred to as "mud jacking" and "pressure grouting" as well. Accounts of raising large concrete slabs through the use of hydraulic pressure date back to the early 1900s.

What Is a Hydraulic System? | Definition, Design, and

Mechanical power is converted into hydraulic energy using the flow and pressure of a hydraulic pump. Hydraulic pumps operate by creating a vacuum at a pump inlet, forcing liquid from a reservoir into an inlet line, and to the pump. Mechanical action sends the liquid to the pump outlet, and as it does, forces it into the hydraulic system.

What are Hydraulic Accumulators? How do They Work

Jul 27, 2009 · The hydraulic pump pumps the fluid into the accumulator, which is nothing but a sealed container. The volume of the container is fixed and cannot be changed. But the quantity of hydraulic fluid being pumped inside the container is increasing continuously. So the pressure of the hydraulic fluid inside the container starts to increase.
