Common Hydraulic Cylinder Terms. Stroke – the travel of the cylinder, extended length (pin to pin center) minus the retracted length (pin to pin center). Retract – the length pin to pin center when cylinder is fully closed. Rod/Ram/Cylinder Shaft – the round device that moves in and out of the cylinder. The cylinder can be solid or hallow.

A position measuring system, also known as a position transducer, can use sensors to calculate the distance between two points – for example, the distance covered by the cylinder piston. The system translates the calculated distance into a signal and transmits it to a control system, for example. Position transducers are used in various ...

A: There are two common types of mounts used on log-splitters. There is a four-bolt mount and a two-bolt mount. The four-bolt mount pumps generally come in 5gpm-16 gpm sizes and have a ½" keyed shaft about 1-1/2" long. The two-bolt mount pumps come in 22gpm and 28gpm sizes and have a 5/8" keyed shaft that can differ in length.

Why is my hydraulic pump not working? It follows that if the pump can't get oil it can't produce flow. So check that the reservoir is filled to the correct level, the breather is not clogged, the suction strainer or filter (if fitted) is not clogged, the pump intake isolation valve is fully open and the pump intake line is otherwise unrestricted.
The level sensing unit has a tolerance of about one inch side-to-side and about five inches front-to-rear. Using a round bubble level, if ½ of the bubble is in the bulls-eye, that is within the tolerances. If the coach is not level within the tolerance, the sensing unit may need to be adjusted. Refer to question 93.

Hydraulic fracturing, informally referred to as "fracking," is an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures.
The hydraulic solution used depends upon the specific application as well as the size of the filter press required. An Air-Over-Oil Filter Press relies upon an air-assisted hydraulic cylinder. Air-assisted hydraulic cylinders use an air-operated intensifier pump to build hydraulic pressure for closing and clamping of the filter press.

Hydraulic control valves are used to start and stop fluid flow into hydraulic cylinders or hydraulic motors. They can be operated either manually or electronically (solenoid-operated). The number of cylinders or motors that a control valve can operate depends on the number of spools on the valve.

Washington State law requires people planning hydraulic projects in or near state waters to get a Hydraulic Project Approval (HPA) from the Washington Department of Fish and Wildlife (WDFW).This includes most marine and fresh waters. An HPA ensures that construction is done in a manner that protects fish and their aquatic habitats.
Conducted properly, hydraulic fracturing (or "fracking") has little possibility of contaminating water supplies. Properly constructed wells prevent drilling fluids, hydraulic fracturing fluids, deep saline formation waters, or oil and gas from entering aquifers. Carefully constructed and operated well sites have the ability to contain potential spills and minimize runoff into
