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.

specially 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.
