Replacement and Refurbishment Services

Replacement and Refurbishment Services

CHPE applies this same attention to detail for customers needing replacement components for existing systems.  Within the constraints of existing powerhouses, turbines, nozzles, and generators, CHPE engineers will design and retrofit the new components to deliver the highest possible efficiency.

Three-dimensional models are created from CAD drawings, laying the groundwork for patterns and castings. Runner castings are tightly controlled, following rigid specifications for alloys, chills, core assemblies, and other requirements. Before the runner is released for final machining and balancing, it undergoes non-destructive testing and heat treating.

CHPE has provided a number of customers with as-kind and upgraded replacement runners and turbine components that have outperformed the original equipment.  Our engineering team can design and retrofit an improved performance runner within the constraints of an existing powerhouse and ancillary equipment.  CHPE adopts a system solution for its upgrades: where required, parts are digitized, 3-D models are created, patterns and castings developed, and related parts upgraded to provide a proper system solution that will allow the plant owner to maximize the performance of the unit.

Our goal at CHPE is to build replacement components that deliver more power and last longer than your originals.

Maintenance & Repair

Maintenance & Repair

Even the best turbine systems experience performance degradation over time. Efficiency drops as waterborne silt wears away runner and nozzle surfaces, as bearings and seals age, and when changes are made to the penstock or other components.

CHPE has the experience necessary for a complete inspection of your current turbine system.  We begin with close examination of the runner and nozzle system, including non-destructive testing (NDT) of your runner using a liquid dye penetrant to detect surface degradation and more serious cracks.

The rest of your turbine system is carefully checked for wear and proper operation.  Bearings and shaft seals are inspected for wear and leakage.  The Hydraulic Power Unit (HPU) is tested, along with all actuators and linkages.  Historical operating data are evaluated to spot changes and trends in system output.

When the turbine inspection is complete, CHPE will provide a comprehensive report of your system condition, including photos of key components and hydraulic surfaces.  If appropriate, we will include specific recommendations for improving system output.

Especially on older systems, turbine refurbishment or a retrofit of select components often results in a substantial increase in production.  CHPE provides complete replacement and repair services to optimize your system performance.

CHPE has established and perfected the fast reaction system. In this system, the vice president is in charge of the system, the user’s services department operates the system, and all the departments and factories work as base. All these members cooperate with each other and work for 24 hours services for domestic user and 72 hours (exclude the time for visa) services for foreign user. In receiving any information or order, give response, dispose or dispatch serve staff in 24 hours for domestic user and in 72 hours (exclude the time for visa) for foreign user.

 In order to provide “better service and good quality product” to the customer, we have performed following practice:

 (1)     Collect the excellence degree of the service staff by receiving the comments of users and referring to the User Satisfaction Investigation Sheet. According to the comment result, make correction and take precaution measures to keep the goal and policy of company.

 (2)     Hold the user’s meeting; make the supply party and demand party communicate face to face, collect opinion and create study opportunity for the relevant staffs in design department, technology department, inspection department and the manufacturing department. All these could make the relationship between the supplier and the buyer more harmonious.

 (3)       Inform our new and old customers about our exploration on new products and improvement on old product improvement every year enable them to take full advantage of equipments and get biggest economic benefits.

Operation Training

Operation Training

Since the generating equipment technology is complex and difficult to master, in order to let customer grasp the technology better and bring the equipment into full play as soon as possible to get best economic benefits, the company has established a training system of user. It is held once a year to train the senior management staff, senior technology staff, and maintenance monitor and operation workers of power station. The main contents of training include specialized introductions of the generating equipments, description of manufacturing technology and disposition of typical failures with an emphasis on the design, technology, maintenance and disposition of failures of our products. By mutual communication on the spot or giving assistance by illustrating the concrete products, the trainees can grasp the product of our company as soon as possible and we have received favorable comment from our users.
