It is designed to handle many difficult applications including fluids difficult to seal and applications requiring zero emissions. Every day in over 1, installations, Goulds process pumps prove why they are the industry standard for performance. A heavy duty bearing frame and shaft, extra thick wall sections and easily manjal wear parts add up to many years of service even under the severest operating conditions. In addition, the CV can handle liquids entrained with air or gas. Overview Literature Drawings Selection Tools.

Engineering for Life At Sea Jastram Engineering is built on the understanding of how critical steering is to the operation of any vessel. Products — Wagner Engineering Ltd. Under emergency manual hydraulic steering the numbers of turns depends on the size of the actuators.
All moving parts are encased in a greased filled, heavy ductile iron jastarn and are protected from corrosion and mechanical damage. Alignment with shims and preparation of flat mounting beds are not necessary.
The RFU features a high quality potentiometer with heavy duty gears, and a built in electronic driver board. With electric drive systems ranging from the low-cost 3-step control for onshore manoeuvring to the frequency-controlled drive for offshore dynamic positioning Jastram offer transverse thrusters for a wide variety of vessel types.
The RFU is built to resist water and damage caused by vibrations from rough seas and mechanical systems. Jastram Jog Levers operate either completely on as long as the switch is activated or completely off when it is released.
Powerunits are available to meet specific design challenges or requirements of the vessel owner, naval architects or shipyard. All electronic circuitry necessary to develop rudder feedback signal and rudder angle signal is contained within the RFU When the traditional steering wheel is turned the EW produces an analog rudder command signal.
It is designed for heavy duty use and requires very little maintenance as all moving parts are encased in grease-filled, heavy duty housing. We design and manufacture marine steering systems to the highest quality standards. These are stand alone systems comprised of three main components: The RFU features a high quality, long life potentiometer with heavy duty gears.
Reliable gears, worldwide service, direct contact to our service department and detailed archived data for each delivered system are well accepted by the maritime industry and international shipping companies.
In the event of a power failure the digital helm seamlessly transfers to manual hydraulic steering. DW shaft dimensions are: The rudder will then follow-up to the position commanded by the movement of the wheel. Only two torque struts arm are required to connect the T-ram to the vessels hull structure. We design and built according to all major marine classification rules and requirements. The X80 Indicators come in 3 sizes to fit all bridge applications.
This set-up would be used in lieu of a Hydraulic Power unit set-up. In essence, they start and stop the electric motor which drives the hydraulic pump powering the steering gear. Rudder Feedback Unit We provide dependable engineered marine steering solutions jastrab. Steel Model Cylinders S series. Galvanic cathodic protection CP is calculated and installed to protect the system for up to 5 years. Matching of ram capacity to rudder torque provides effective steering at the least cost.
When the steering lever is moved to the desired rudder angle, the rudder will follow-up to the position requested b the lever.
The EW provides full follow-up electric wheel control. Jastram B Model Actuators are double-acting equal displacement cylinders which are directly connected to a tiller. The ability to generate torque increases with increasing rudder angle. To improve performance the propeller design is continuously modified according to the latest developments. T Ram Rapson Slide Actuators. Transverse Thrusters The stainless steel ring in the propeller tip region protects the tunnel against cavitation damage.
They provide a proven, trouble free system for all types of commercial vessels. For those vessels where space is a large concern. Our line of products ranges from simple manual iastran for small vessels, to digitally-controlled and integrated systems for large ships. With worldwide representation and an in house ability to communicate in twenty-one languages, customers can be assured that any question will be answered quickly.
The wheel is not supplied with the digital wheel. Besides electric motor brakes, hydraulic, pneumatic and electrically driven disk brakes are available for new builds and retrofits.
Digital Wheels are unique input devices which provide full follow-up digital electric control.

Vudolar These are stand alone systems comprised of three main components: Only two torque struts arm are required to connect the T-ram to the vessels hull structure. They provide a proven, trouble free system for all types of commercial vessels. Up to five indicators can be used with a mixture of forward and jsatran scale meters. Steel Model Cylinders S series. The T-ram assembly mounts directly on the rudderstock and self-aligns, supporting its own weight. The EW provides full follow-up electric wheel control.

When I submitted proposals to publishers for the first edition of this book, they posed two questions to me: Oversampling Delta-Sigma Data Converters: This is for two reasons: Most computer systems are built using a handful of such abstractions.
