| Abstract: | Main reasons of short service life of the piston in reciprocating pump operated in the mine at present are pointed out. Operation regime, configurational peculiarities, and the materials used of the piston are investigated analytically. Four types of damages of the piston-thorn-leakage, nibbling, mechanical fatigue, and thermal fatigue are advanced. A new piston with improved construction, material, and operation regime is successfully developed which can increase service life of the piston from about 20 hours upto 180 hours. |
