3/6/2019 · Water jet cutting requires a high pressure, which can be up to 6200 bar, which results in an outlet speed of 1000 m/s. The water jet cutting process is carried out by means of a high-pressure water jet alone or by the addition of an abrasive medium. There is only a small amount of heating.
DETAILED DESCRIPTION OF THE INVENTION. The mobile concrete pump shown in FIG. 1a to c comprises a chassis 10, a four-arm articulated mast 14disposed on a substructure 12affixed to the chassis, serving as the carrier for a feed line, as well as two front support booms 16′, 16″ and two rear support booms 18′, 18″.

Position Feedback for Motor Control Using Magnetic Sensors
The Concrete Pump was particularly important in revolutionising the construction of large high rise buildings. Previously cranes had been employed to lift large buckets (or skips) full of concrete up to where it was needed. A crane could lift one bucket at a time, normally holding around 2 cubic yards of concrete.
BP 3763 GB 11 Better efficiency due to fewer hydraulic components In purely hydraulic control systems, there are valves, throttles, regulators, etc. that control all the functions. With EPS, all this is taken on by a computer. Few hydraulic components are required, i
21/3/2017 · A closed loop pump draws most of its flow directly from the return flow of its actuator(s). Unfortunately, the pros, cons, and implications of each are not quite as easy to summarize and understand. In order to avoid the pain and consequences of choosing the wrong type of circuit for your application, it is wise to think about the big picture design intentions and analyze the merits of each
Concrete pumps for sale nz can meet the long-distance pumping requirements of high quality concrete. It has wide application in new rural construction, bridge construction, high speed rail, tunnel, air port and wharf, etc, and can realize on-site loading, mixing and pumping, which greatly reduce the complex procedure, quicken the process of concrete pouring and shorten the project period.
This application note is dedicated to sensors for position feedback in motor control. Feedback for brushless direct current (BLDC) motors with block commutation by using Ha ll switches as well as high resolution encoder feedback
Openings 60 may be slotted to allow adjustment of actuator assembly 44 such that, when actuator arm 78 is in the first position shown in, for example, FIGS. 4, 5 and 6, edge 78 a of actuator arm 78 is in alignment with formed edge area 40 a of control arm 40.
1/3/2015 · Abstract. This paper presents a new hand controller interface that addresses practical challenges to implementing coordinated position control (CPC) for an excavator arm. The new interface uses a hybrid control scheme with closed-loop CPC of the excavator arm and open-loop flow control of the swing. CPC is achieved using a joystick that is
