Description
PURPOSE:
- pressure source for hydraulic testing of pressure vessels;
- test stand control panel;
- independent source of pressure.
OPTIONS:
- PKTBA - PGS - PS - the unit is equipped with a clamp pressure proportional control system. The use of a programmable logic controller makes it possible to test valves in a safe mode, excluding axial compression exerted on the body during testing.
- PKTBA - PGS - M - mobile version of the installation allows you to test on site using plugs.
- PKTBA - PGS - A - the installation allows you to test valves in a semi - automatic mode. Optionally, it can be equipped with a clamping pressure proportional control system.
FUNCTIONS:
- Creation of liquid pressure up to 160 MPa.
- Smooth (stepless) pressure control:
- hydrotesting 1.0.. .160 MPa;
- pneumatic tests 0.05.. . .1 MPa (0.5.. . .20 MPa or 1.. .40 MPa).
- Smooth clamping control of the test bench hydraulic cylinder.
- Automatic maintenance of the set pressure.
- Measurement of leaks in the gate of the tested product by drop and bubble methods.
- Control over the testing process using panel pressure gauges with a measurement error of 1.0% (0.6% - at the request of the customer) and pressure sensors with a measurement error of 0.25% .
- The design of PKTBA - PGS provides fittings for the installation of control pressure gauges with the required error.
ADVANTAGES:
- Pneumatically controlled locking elements are used in the control circuit. This frees the operator from having to open and close numerous valves and makes the station control process simple and reliable.
- The stations have a separate filling line to reduce test preparation time.
- For ease of operation, the control of the hydraulic cylinder of the test bench clamp can be carried out both from the control panel and with the help of an external pedal.
- The scheme of external connections is made using quick disconnect connections with a guaranteed service life of 10,000 cycles. This significantly reduces the time required to perform preparatory and final operations.
- A fine water filter is installed at the water inlet, which prolongs the service life of the station.
- Possibility of completing PKTBA - PGS - PS with a system for filling the tested products with water.
- High accuracy of test pressure measurement using built - in pressure sensors with an error of 0.25% (PKTBA - PGS - PS).
EQUIPMENT:
- pressure generating unit with stand control panel:
- 1 or 2 pneumohydraulic multipliers
(depending on the model);
- control, regulation and management equipment.
- oil hydrostation;
- device for measuring air and water leaks;
- air preparation unit;
- coarse and fine water filters;
- foot control for the process of clamping the product during testing;
- set of high pressure hoses with quick couplings;
- ZIP kit.
