We specialize in both the production of hydraulic power units and the manufacturing of specialized test benches.
The offered solutions are designed in cooperation with the Client, according to their requirements, and tailored to the needs of the investment.
The designed test bench enables pressure and leak testing of pipelines.
The test bench consists of: a test chamber, an oil hydraulic system, a water system, a pneumatic system, and an electrical control system.
The task of the oil system is to open and close the test chamber cover using hydraulic cylinders and to supply oil under appropriate pressure to the multiplier chambers. The pressure at the multiplier is regulated by means of a proportional valve.
The pressure on the oil pumps is limited by UZPD6 and UZPS6 type relief valves.
The water system is used to supply the test connections with water at the required pressure. The pump unit pre-fills the multiplier and the tested element, after which the pressure is increased using the multiplier. Pneumatically actuated two-way valves allow for supplying the appropriate connections in the test chamber and engaging the measuring systems.
The tested elements are connected to quick-release couplings on the water manifolds.
Water is also used to fill the test chamber tank, in which leak tests of components are carried out using compressed air.
A movable platform is mounted inside the tank, on which the tested assemblies are placed in order to submerge them in water.
The movable platform is raised and lowered by means of an electrically driven screw jack.
The water in the test bench is subject to filtration and UV lamp sterilization.
The pneumatic system is designed to supply the test connections with air at the appropriate pressure and to maintain the control pressure required for pneumatically operated valves.
The compressed air manifold is submerged in water together with the tested component.
The oil and water tanks are equipped with electrical minimum liquid level switches, which protect the pumps against dry running.
