Tandem hydraulic protectors type TGKT21MA6L2DE EI

Hydroshields of monoblock modular design (hereinafter referred to as "hydroshields"), designed for: <ul> <li>- protection of submersible oil-filled electric motors of series (H, B) of PEDs from penetration of formation liquid into their internal cavity;</li> <li>equalisation of pressure in the internal cavity of the motor with the pressure of formation fluid in the well;</li> <li>gas removal from the internal cavity of the engine into the annulus space through valves installed in the hydraulic protectors;</li> <li>compensation of oil leakage and thermal changes of oil volume in them during engine operation and shutdown;</li> <li>absorbing the axial load from the pump shaft when the pump is operated without axial support.</li> </ul>Depending on the cross-sectional dimension, hydraulic guards are manufactured in dimensions: 2A, 3, 4, 5, 5A, 6, 8. The dimension conditionally determines the minimum diameter of the operating column: 89.0 mm, 100.0 mm, 120.0 mm, 121.7 mm, 130 mm, 148.3 mm, 205.7 mm respectively. Type of climatic execution and category of placement B5 according to GOST 15150-69 at the upper values...
