Equipment We Work On
Turbine Generators
Your turbine generators are the heart of your operation. Imbalance or misalignment here creates cascading problems across the entire system. We perform on-site hydropower balancing and laser alignment to keep rotors running true and vibration levels safe.
Pump Systems
Pump runners and couplings demand precision. Off-balance pump runners cause excessive vibration and accelerate bearing wear. We balance runners on-site and align pump trains to reduce strain on supporting equipment.
Large Motors
Auxiliary motors drive gates, cooling systems, and other critical support equipment. We inspect, repair, and balance large motors in our shop and perform field support when needed to minimize downtime.
Couplings & Drive Systems
Misaligned couplings and drive systems create premature wear and unexpected failures. We use laser alignment technology to ensure every coupling is perfectly aligned, reducing vibration and extending component life.
Common Hydropower Problems We Solve
Excess Vibration
Excessive vibration reduces equipment lifespan and can lead to catastrophic failures. What you observe: unusual noise, heat at bearing pedestals, visible equipment movement. How we fix it: On-site vibration analysis identifies the root cause—imbalance, misalignment, or bearing wear. We then perform balancing, alignment, or recommend repairs based on real diagnostic data.
Misalignment
Turbines, pumps, and motors must run in perfect alignment to operate efficiently. Misalignment creates side loads, increases bearing stress, and generates unnecessary vibration. How we fix it: We use laser alignment technology to correct coupling and shaft alignment, often during scheduled outages when equipment is accessible.
Bearing Failures
Bearing failures typically don’t happen suddenly—they develop over time. Early detection prevents forced outages and catastrophic damage. How we fix it: Routine vibration trending and predictive maintenance catch bearing wear early, giving you time to plan repairs before failure occurs.
Unplanned Outages
Unplanned outages are expensive and disruptive. Many are preventable with proper monitoring and maintenance. How we fix it: Our preventative maintenance program uses vibration analysis and routine inspections to identify problems before they force you offline.
Field Services for Hydropower Plants
1. Balancing
Rotating equipment must be perfectly balanced to run safely and efficiently. Imbalance—whether in turbine rotors, pump runners, generator shafts, or couplings—creates vibration that damages bearings and reduces component life.
PDS Balancing brings on-site balancing expertise directly to your plant. We balance turbine rotors, generator rotors, pump runners, and couplings during your scheduled outages. Our team works within tight outage windows, using field-proven techniques and portable balancing equipment to correct imbalance while your equipment is stationary.
For large rotating equipment common in hydropower plants—turbines spinning at thousands of RPM, massive pump runners, and heavy generator shafts—precision matters. Incorrect balancing creates more problems than it solves. We bring the expertise and tools to do it right the first time, ensuring your equipment runs smoothly and reliably.
2. Vibration Analysis
Vibration tells a story. High vibration, changing vibration patterns, or abnormal frequency components all indicate underlying problems—bearing wear, misalignment, cavitation in pumps, or imbalance.
Our on-site vibration analysis service captures real operating data from your turbines, generators, pumps, and motors. We take measurements during normal operation, then analyze the data to diagnose problems and track trends over time. This isn’t guesswork—it’s condition-based decision making backed by real data.
We provide detailed reports showing vibration levels, frequency spectra, and trend analysis. We help you understand what’s normal for your equipment and what signals trouble ahead. By trending vibration over months or years, we catch developing problems early—bearing wear, alignment drift, or impending imbalance—giving you time to plan maintenance before equipment fails and forces an unplanned outage.
3. Preventative Maintenance
Reactive maintenance—fixing things after they break—is expensive and disruptive. Preventative maintenance catches problems early and keeps equipment running longer.
PDS supports your long-term reliability with routine vibration checks and periodic alignment verification. We visit your plant on a schedule that matches your equipment’s operating conditions, taking vibration measurements, checking alignments, and looking for early signs of bearing wear, shaft issues, or imbalance.
This ongoing support means you’re never surprised. You know the condition of your critical equipment and can schedule maintenance during planned outages rather than dealing with emergency calls. Early detection translates to lower maintenance costs, extended equipment life, and improved plant safety and reliability.
4. Electric Motor Repair
Support equipment motors—for gates, cooling systems, pumps, and auxiliaries—are vital to keeping your plant running. When these large motors fail, so does the equipment they drive.
We provide large motor inspection and repair in our full-service shop, plus field support when equipment must be repaired on-site. Our team inspects motor windings, bearings, shafts, and housings. We repair or rewind motors to OEM specifications and return them ready for service. When you need field support during an outage or emergency, we’re equipped to help.
Whether your motor fails in the shop or in the field, we minimize downtime and restore full operating capacity.
5. Laser Alignment
Perfect alignment reduces vibration, extends component life, and improves equipment efficiency. Misalignment in couplings, pump trains, and turbine auxiliaries creates side loads, accelerates bearing wear, and generates unnecessary stress on shafts and housings.
We perform laser alignment services during scheduled outages or after equipment changes. Using precision laser alignment technology, we align couplings and pump trains to tolerances that minimize vibration and extend equipment life. Whether you’re performing routine maintenance or commissioning new equipment, laser alignment ensures everything runs true from day one.
On-Site Support & Outage Work
We understand that hydropower plant outages are high-pressure situations. Downtime is expensive, windows are tight, and the work must be done right the first time.
Our team is experienced in outage environments. We coordinate with your plant operators, work within your outage schedule, and communicate clearly about progress, findings, and next steps. We come prepared with the right tools, equipment, and expertise, so we’re not learning on your time.
When you schedule maintenance with PDS, you get a dedicated team focused on your equipment and your timeline. For emergencies—unexpected vibration, bearing noise, or sudden equipment degradation—we offer 24/7 support across the Pacific Northwest. We respond quickly, diagnose problems accurately, and execute repairs efficiently to get you back online.
Reports and documentation are provided after every service visit, giving you a clear record of what was done, what we found, and what we recommend for future maintenance.
Predictive & Preventative Work for Long-Term Reliability
The best maintenance strategy balances prevention with responsiveness. Waiting for equipment to fail is expensive. Over-maintaining is wasteful. The answer is condition-based maintenance supported by reliable data.
Our hydropower vibration analysis and trending programs give you that data. By monitoring equipment condition over time, we help you:
- Extend equipment life through early detection of wear and degradation
- Reduce unplanned downtime by catching problems before they force outages
- Lower maintenance costs by performing work only when needed, not on a calendar
- Improve plant safety by preventing catastrophic failures
We work with your maintenance team to build a maintenance strategy tailored to your plant’s equipment, operating conditions, and reliability goals. Whether you need weekly vibration checks during critical periods or quarterly trending programs, we design support around your needs.
