Four Steps to Routine Pump Pressure System Inspection
Crown Pump Pressure Systems are built to provide years of trouble-free service with little to no maintenance. A schedule for routine pump pressure inspections will ensure that these work horses of the industry provide the most accurate readings with minimum downtime. It is recommended, that maintenance personnel establish and follow a regular inspection cycle based on use of system, environment, and overall equipment. Following the steps below will help to keep your Crown pump pressure system accurately measuring drilling fluids.
Step One: Complete System Check
- Check the entire system Gauge (CG602 or CG603 Series) , Hydraulic Hose (CH113) , Gauge Protector (CD106) for any bent, damaged, worn or loose parts.
- Replace any worn parts as needed following maintenance guidelines.
- Gauges should be repaired by fully trained technicians. Contact Crown for gauge repairs.
Step Two: Protecting the Gauge Protector
- Check the gauge protector housing for any cracks, cuts, or dents.
- Determine if wear is causing hydraulic fluid leaks. Repair or replace as needed.
- Inspect the small holes inside the housing. These holes should be free of debris so that clean fluid can reach the gauge.
- Inside the gauge housing is a lip where the diaphragm cup sits. Lip must be free of debris to keep the cup from being damaged.
- Diaphragm cup should be free of cuts, nicks, or tears or pressure will be lost. Replace as needed.
Step Three: Inspecting the Hydraulic Hose
- Inspect the entire hose for cuts, cracks, and kinks. If kinks can be straightened, then do so. If any fraying, cuts, or cracks occurs, hose should be replaced.
- Check all hose connections to make sure they are tight.
Step Four: Gauging the Gauge’s Appearance
- Check the gauge glass for cracks, chips or pits. Clear fluid is used to lessen vibrations and increase gauge sensitivity. Loss of fluid can result when gauge glass is compromised.
- Inspect gauge housing for any leaks at connection points.
- Determine is gauge pointer is connected properly. If pointer is loose or detached, the gauge will need to be serviced.
- Gauges should be serviced by a fully trained gauge technician. Contact Crown for gauge repairs.
Proper service and repair is important to the safe, reliable operation of all Crown Oilfield Instrumentation equipment. The four steps to routine pump pressure inspection described above are recommended by Crown Oilfield Instrumentation as regular inspection procedures to ensure long pump pressure system life. It is importance to note that regular inspections are necessary; however, they will not prevent all loses of pressure, especially where service methods used do not comply with recommended methods in operating manual. Warnings against the use of specific service methods that can damage the equipment or render is unsafe are stated in the manuals. It is also important to understand these warnings are not exclusive. Crown Oilfield Instrumentation could not possible know, evaluate and advise the service people of all conceivable ways in which service might be done or of the possible hazardous consequences of each way. Accordingly anyone who uses service procedures, or tools, which are not recommended by Crown Oilfield Instrumentation, must first satisfy himself thoroughly that neither his safety nor equipment safety will be jeopardized by the method selected.
