Renewal of НШ-К round gear type hydraulic pumps with the use of combined method

Cite item

Full Text


Basic theoretical background of obtaining the prolonged life of round gear hydraulic pumps during the repair is given. Physical-mechanical properties of coatings formed with the use of combined method are investigated. A mathematical model of relationship between the gaps in conjunctions with internal leakage in a hydraulic unit is obtained. The possibility of round pump repair with the use of combined method is confirmed.
