For proper using of hydrostatic pressure test unit, hot bath and end caps below considerations will make very long life-time of parts used inside the machine. For the valued customers note below brands used as internal parts with high quality.
1- Main pump: Bertollini Italy
2- Pressure sensors: WIKA Germany
3- Solenoid valves: ODE Italy
4- High pressure accumulators membrane: Italian brand
5- Temperature controller for Hot bath: Autonics Korea
6- Electric parts: Schneider Electric
Beside above mentioned high quality parts that are used, for long-life of the machine below predictive maintenance and maintenance procedure need to be considered by the operators.
Preventive Maintenance
- Water supply need to be filtered with low hardness value
- Samples need to be cleaned before putting them inside hot bath
- Sensors need to be checked every month to have accurate pressure value in all stations (with calibrated pressure read device)
- Temperature sensors need to be checked and internally calibrated every 6 month (with calibrated temperature readout)
- Water filters of hot bath and pressure unit need to be checked every month to be sure water is coming to pump properly
- Electric power coming to the computer need to be stabilized power source (preferably UPS is used)
- Automatic refill sensor and valve of hot bath need to be checked periodically to be sure about functioning
- Greasing the end caps o-rings will cause very less damage to them during assembly
- Every 3 months, water inside the hot bath need to be replaced in case of dirt come into that from outside when putting samples inside it
- check the oil level of main pump and add oil in case of need
Maintenance Operation
| Description | Frequency |
| Check if water main line is connected | Daily |
| Check if compressed air line is connected | Daily |
| Check if water inside bath is clean and if needed replace it | Weekly |
| Check the main compressed line pressure in the regulator | Daily – Before Startup |
| Check and replace the water filters of purifying system | When needed (If there is not any water comping out of the water purifying unit) – Yearly |
| Check if there is not any leakage from piping and fittings | Daily before and during the test |
| Check before power off of the machine , Need to click on “Quit” key on software | Daily |
| Check if you set proper value in “Inpercent” parameter for automatic stop of the line in case of sample burst. There is 2-step diagnose system for the machine to understand burst and leakage of the sample during testing. This will protect damage to the pump. | Daily |
| Check the user manual of the main pump Bertollini piston pumps | As required |
| Check if circulation pump of hot bath is working | Daily |
| Check if water level switch of the bath is working properly . Before startup of heating system of the bath be sure bath is full of water | Daily |
| Check if pneumatic door of bath working properly, this is important for safety. Before test start be sure to close the door | Daily |
| Check if overflow line of bath is working properly and not blocked | Weekly |
| Check if you have proper earthing connection to the body of the machine. This is very important especially in case of failures of heating resistance elements | Monthly |
| Check if supplied compressed air is dry. Wet compressed air will damage pump, digital pressure regulator… | Weekly and in machine startup |
