T- Turbocharger / T- Vtr 4 Series Turbo Rotor Assembly For Marine Propulsion Engines

T- / T- VTR series marine turbocharger features:

T- VTR 4 series turbocharger rotor assembly / rotor complete belongs to one part of the T-/T-VTR 4 series exhaust gas turbocharger. The T-/T-VTR series marine turbocharger is created for two-stroke, low-speed and four-stroke, medium-speed heavy-duty diesel engines. The engine power output is from 700 kW to 18,500 kW per turbocharger. T-VTR series turbocharger has been widely applied to marine propulsion engines (esp. at part load), stationary power plants and units burning heavy oil and in continuous operation. The advantages are as following:

• Optimum engine perforce in part-load operation
• The optimum match with all types and designs of engines due to the modular concept adoption
• Connectors on the compressor side allow water cleaning during operation
• External bearing
• Integrated lubrication system
• The rotor shaft can be removed without distling the gas ifolds, or pulling of the compressor wheels
• Low friction losses of the external antifriction bearings
• The T-VTR 4 series is capable of high pressure-charging, the pressure ratio from 3.7 even to 4.2.

Brief introduction of The turbocharger rotor assembly / rotor complete:

The turbocharger rotor assembly / rotor complete consists of compressor impeller, blade shaf/turbine shaft/rotor shaft and partition wall complete.
The compressor impeller is of aluminium alloy or the more expensive titanium. ufactured from a single casting it is located on the rotor shaft by splines. Aluminium impellers have a limited life, due to creep, which is dictated by the final air temperature. Often the temperature of air leaving the impeller can be as high as 200°C. The life of the impeller under these circumstances may be limited to about 70000 hours. To extend the life, air temperatures must be reduced. One way of achieving this is to draw the air from outside where the ambient air temperature is below that of the engine room. Efficient filtration and separation to remove water droplets is essential and the impeller will have to be coated to prevent corrosion accelerated by the possible presence of salt water.

The turbocharger rotor shaft is equipped with components such as a compressor and a turbine impeller, and has a complicated structure and a large weight.

Marine Turbo factory, founded in 1999, is a professional ufacturer for marine turbocharger replacement spare parts and components.

The Marine Turbo workshop, occupying more than 18,000 square meters, is located in Yangtze river delta region which is close to the international metropolis, Shanghai China. The company owns more than 100 units of ufacturing equipment and testing instruments, such as CAD, precision casting production line, four axis and five axis machining center, three coordinate measuring instrument, CNC lathe milling machine, metal cutting equipment with nondestructive flaw detection, etc.

With the advanced mechanical processing technology, Marine Turbo is fully in accordance with the strictly production process control method of military products to age the production line in the workshop in order to ufacture the high quality of turbocharger replacement parts. In the mean time, Marine Turbo factory introduce and absorb the latest technology at home and abroad that the factory independently develops the various types of turbocharger components and which are applied for engineering machinery and marine auxiliary machinery, such as the turbine blades, turbine shaft, compressor impeller, diffuser, oil pump, nozzle, etc.

The Company has also supplied nearly hundred kinds of engine parts for US client's yatchs production, and several creative technologies have been recorded in our domestic marine ufacturing industry.

In order to provide the reliable products, the company has passed the ISO9000 Quality agement System certificate in 2001, and also some of the products are certificated by CCS (China Classification Society Certification) and RINA Certificate.

Satisfying customers with supreme quality and reliable services for marine turbocharger replacement parts is the aim across the whole Marine Turbo company.

Marine Turbo Keep a Large Inventory for Quick Delivery

Marine Turbo has more than hundres of types of replacement parts for customers to choose quickly. Among them, 90% of the product models Marine Turbo has the inventory, can meet the turbocharger overhauling, maintenance and repair needs for various brands with a quick response and reasonable price.

According to the feedback and sales situation of customers seasonally and yearly, our company analyzes and make the turbocharger replacement parts’ production plan, in order that our company can keep the inventory for common spare parts all the time, while as for some non-common parts, we will keep the long-term inventory of semi-finished products.

The purpose to build our large inventory is to save time for customers’ waiting for repairing spare parts as much as possible, so that to help customers resume operations as soon as possible, and ultimately improve the effectiveness of competition.

We recommend that customers can make the plans to establish a small stock for your own to minimize the time lost as much as possible.

Marine Turbo look for the professional local distributor for turbocharger replacement parts around each country of the world.

Marine Turbo products has sold to all over the world. From the feedback from various places, we have been highly recognized for the quality of our products and delivery time. However, in order to better serve the local market, we are looking for professional turbochargers aftermarket parts distributors in different countries of the world, so as to establish a local inventory chain through cooperation and assessment for a certain period of time.
The aim to build local chain is to enable end users to shorten the waiting time for the turbocharger spare parts as much as possible, then to save costs and improve the market competition effectiveness for end users.
