Description
Technical field
The utility model belongs to field of mechanical technique, a kind of concrete pump hydraulic pressure cooling unit of saying so more specifically.
Background technique
For the hydraulic pressure cooling system that guarantees concrete pump can proper functioning; Will the hydraulic oil of hydraulic system be cooled off; Be controlled in the rational oil temperature scope, the hydraulic pressure cooling system of existing technology adopts two kinds of radiating modes usually, and the one, main system oil return heat radiation; The 2nd, the heat radiation of main pump draining, the two all comes system is dispelled the heat through radiator; When taking main system oil return heat radiation, pass through radiator, can reach radiating effect because of most of oil return, but because the hydraulic shock of main system oil return is bigger, the easy explosion of air cooler; When adopting the heat radiation of main pump draining, though radiator is not worked the mischief, its flow is little; The fluid of heat radiation is few; Do not reach the requirement of hydraulic system cooling heat dissipation, so that the hydraulic system temperature causes the too early damage of hydraulic system element seriously above normal serviceability temperature.
Summary of the invention
In order to address the above problem; The utility model provides a kind of concrete pump hydraulic pressure cooling unit, and described concrete pump hydraulic pressure cooling unit is made up of power motor, main pump oil circuit, leakage passage, tooth blowback oil circuit, blower fan, program controller, temperature detect switch (TDS), main oil pump, gear pump, vane pump, fuel feeding road, radiator, hydraulic oil container, it is characterized in that the front end of power motor is provided with main oil pump; The front end of main oil pump is provided with gear pump; The front end of gear pump is provided with vane pump, and the fuel feeding road connects main oil pump, gear pump and vane pump respectively, and the lower end of fuel feeding road, leakage passage and tooth blowback oil circuit all is provided with radiator; The oil return of main oil pump is directly got back to hydraulic oil container through the main pump oil circuit; The draining of main oil pump housing is got back to hydraulic oil container through leakage passage, tooth blowback oil circuit connection gear pump and vane pump, and the top of radiator is provided with blower fan; Blower fan connects program controller, and program controller connects temperature detect switch (TDS).
The beneficial effect of the utility model is: concrete pump hydraulic pressure cooling unit cools off the oil return in each hydraulic circuit respectively the hydraulic system element is worked under rational temperature; Can not raise and cause the power loss in the system, and prolong the working life of hydraulic element and hydraulic oil in the hydraulic system because of temperature.
