Определение тепловой мощности, отводимой гидробаками насосной станции геохода

One of the directions on increase in speed of carrying out auxiliary and preparatory developments during the mining and construction of tunnels is improvement of tunneling equipment. In article the new class of tunneling cars – the geokhods is considered. Creation of the geokhods is connected with attempt to increase the speed of carrying out a driving and, eventually, to accelerate development of underground space. One of key systems of the geokhod is the pump station. At determination of parameters of a hydraulic actuator a necessary stage is determination of efficiency of a hydraulic actuator and carrying out thermal calculations. Maintenance of the thermal mode at the necessary level is based on ability of elements of pump station to take away excess thermal power. A paramount element in this process is the hydrotank. In work the thermal power which is taken away by hydrotanks of pump station of the geokhods provided that elements of pump station are placed in the geokhods case, namely – in its tail section is determined. Surface area was defined for the hydrotanks having section in the form of a segment and ring sector. Comparison of the taken-away thermal power for hydrotanks of these forms and various capacity is carried out. Advantage of hydrotanks like «segment» is established. Effective ways of increase in the taken-away thermal stream are revealed. Ways on further reduction of the geometrical sizes of hydrotanks of pump station of the geokhodes are planned.
