How pressure control valve works

Published on April 28, 2017

The hydraulic system is incomplete without pressure control valve. This makes them an essential part of every hydraulic device. There are a number of functions which are performed by this device. The upper pressure is not only maintained but these devices also ensure that a particular pressure is maintained in a certain part of device or circuit to which it is associated. The two main types are open and closed valves. Both are used in various industrial applications. An example of the closed valve is unloading and that of the open valve is a relief. The concept of this appliance is not simple and thermodynamics are applied while these are manufactured. Basic of the device are as follows: read more

The most common gantry cranes feature two supports. One of the pillars can be rigidly connected to the axle (rigid or spatial support), and the other one is hinged (flexible or flat feet). In gantry crane with a span (distance between the crane rails) of less than 25 m both bearings are hard. Track each of the pillars of heavy crane (lifting capacity of 1,000 tons or more) may consist of two or more rails (undercarriage in this case have the spatial equalizer suspension). In some cases the rails are placed at different levels of support at different heights. The semi-crane design implies the bridge resting on one side of runway, and the other one – on the support legs. Trucks are moving the bridge crane. The mechanism of the trolley as lifting mechanism can be mounted on a trolley (autonomous trolley) or on a metal bridge structure. Lifting mechanism is oftentimes mounted on the metal, and a truck equipped with a movement mechanism. Gantry crane has a metal structure: mechanisms of lifting cargo, the trolley and crane movement. Grab cranes are equipped with a special gripper and winch mechanism in the presence of lifting mechanism circuit grapple. If there is a need for orientation of cargo, the carriage is provided with a rotatable part as steel truck cranes. read more

In the modern field of metalworking, mechanical method of working with steel alloys is constantly evolving.

However, technological progress contributes to the emergence of new, high-tech materials that can hardly be subjected to mechanical stress. Therefore, many productions began to switch to a completely new, high-tech treatment. Ultrasonic machining is a decent example of a modern technology that can not only solve complicated manufacturing tasks, but also be cost-effective.
