PKTBA-PGS

Pneumohydraulic pumping station

Pneumohydraulic pumping station

PNEUMOHYDRAULIC PUMPING STATION

PURPOSE:

• Pressure source for hydraulic tests of pressure vessels.
• Control panel of the test bench.
• Independent pressure source.

FUNCTIONS:

1. Liquid pressure up to 1600 bar (23200 psi).
2. Continuous (stepless) pressure control for:
• hydraulic tests 10...1600 bar
(145...23200 psi);
• pneumatic tests 0,5...10 bar
(7...145 psi) (5...200 bar (72,5...2900 psi) - by customer's order).
3. Smooth control of the test-bench hydraulic-cylinder clamp.
4. Automatic maintenance of the set pressure.
5. Valve gate leakage measurement by the drop and bubble methods (see B).
6. Control of the test process by the pressure-gage panel with the measurement error of 1.0 %. (0.6% as requested by customer).
7. The PKTBA-PGS is equipped with nipples to connect the test gages with the required accuracy (see А).

COMPLETE SET:

• pressure source unit with the bench control panel:
- 1 or 2 pneumohydraulic boosters (according to model);
- monitoring, adjustment, and control equipment;
• air preparation unit (С);
• preliminary and fine water filters (D);
• pedal for the valve-clipping control during the test (Е);
• air and water leakage control unit (В);
• a set of high-pressure quick-connect hoses;
• a set of spare parts, tools, and accessories.

EQUIPMENT ADVANTAGES:

• The PKTBA-PGS control circuit uses pneumatically controlled gate elements. This releases the operator from opening and closing numerous needle valves and makes the unit control process simple and reliable.
• The equipment has separate filling line to reduce the test preparation time.
• For convenience, control of the hydraulic cylinder of the test bench clamp can be performed from both the PKTBA-PGS control panel and remote pedal (see E).
• The PKTBA-PGS external connection diagram uses quick-connect joints with warranted operation life of 10,000 cycles, which significantly reduces the time required to complete preparation and final operations.
• The compressed-air supply line has the air-preparation unit and ensures class 0 air supply even when the pneumatic network contains polluted air (see C).
• To extend the unit operation time, the PKTBA-PGS water input is equipped with a fine water filter (see D).
