<p>The invention relates to a portable installation for cleaning and lubricating the pipes provided with cut-off plates, particularly the ones with difficult access thereto, meant for hydroelectric power stations. According to the invention, the installation comprises a positive displacement pump (P) with pneumatic driving, said pump being coupled to a compressor ( C) which supplies a pressure of 4...10 bar, controlled by some direction valves (S1, S2 and S3) and visualized by a pressure gauge (M) of 0...400 bar, the pump (P) being connected through a hose (F) to a fast coupling (CR) located at the aimed at lubricating point, the pumped liquid used for the cleaning operation, such as a hydraulic oil H9/1 being stored in a first tank (R1) connected to the pump (P), and from a second tank (R2) also connected to the pump (P) there being extracted mineral fat LiC2, introduced into the circuit for the lubricating operation</p> |
