Abstract
The utility model provides a crane hydraulic pump heating flushing system which is connected with a crane hydraulic system and is characterized in that: the crane hydraulic pump heating flushing system comprises a heater, an outlet valve, a filling valve, a flushing hydraulic pump and a motor. The heater is arranged at the lower part of the inside of a hydraulic tank of the crane hydraulic system; an oil inlet of the flushing hydraulic pump is connected with an oil outlet of the hydraulic tank through the filling valve; the oil outlet of the flushing hydraulic pump is connected with a flushing feed circuit of the crane hydraulic system through the outlet valve; and the flushing hydraulic pump is driven by the motor. As hot oil is used for heating and flushing a pump body to increase the temperature of the hydraulic pump, thus reducing the viscous resistance of the hydraulic pump during start and being beneficial for starting under extremely cold environment; as an external alternating current power is adopted, the power of a jar is not consumed; moreover, limitation of heating and flushing time is avoided and the effect of sufficient heating can be achieved.
Description
Technical field
The utility model relates to the technology of all hydraulic caterpillar cranes cold starting in winter.
Background technique
The large full hydraulic crawler crane is always at outdoor work, and diesel engine directly connects many oil hydraulic pumps by transfer case, adopts closed circuit may reach Shang Shitai.Under the extremely cold in the winter time environment, the hydraulic pressure oil viscosity is very big, and the viscous resistance during the oil hydraulic pump initial rotation may cause the diesel engine can't starting operation.Even with the hydraulic oil container heating, oil hydraulic pump does not rotate, deep fat can't enter the pump housing; Particularly the hydraulic oil of closed circuit fuel tank is not participated in the circulation of pumping system directly, and the deep fat of hydraulic oil container will further increase the difficulty of cold starting with just progressing into the pump housing for a long time.
The model utility content
The technical problems to be solved in the utility model is: a kind of hoist oil hydraulic pump heating rinse-system is provided, can reduces the starting resistance under the extremely cold in the winter time environment of the oil hydraulic pump of all hydraulic caterpillar cranes.
The utility model is to solve the problems of the technologies described above the technological scheme of being taked to be: a kind of hoist oil hydraulic pump heating rinse-system, be connected with crane hydraulic system, and it is characterized in that: it comprises heater, outlet valve, oiling valve, washing solution press pump and motor; Described heater is arranged on the interior bottom of hydraulic oil container of crane hydraulic system, the filler opening of washing solution press pump is connected by the oil outlet of oiling valve and hydraulic oil container, and the oil outlet of washing solution press pump is connected by the flushing feed circuit of outlet valve and crane hydraulic system; The washing solution press pump is by motor driving.
Press such scheme, described motor is connected with external AC power supply respectively with heat pump.
The beneficial effects of the utility model are: by with the deep fat heating flushing pump housing, oil hydraulic pump is heated, the viscous resistance when having reduced the oil hydraulic pump starting is easy to the starting of utmost point cold environment; Adopt external AC power supply, do not consume the electric weight of storage battery, the time length that is not added heat flush limits, and can reach the effect of abundant heating.
Description of drawings
Fig. 1 is a connection diagram of the present utility model.
Embodiment
Fig. 1 is a connection diagram of the present utility model, increases heater 2 in original crane hydraulic system, and washing solution press pump 5 is connected the flushing heating system that original paper is formed with flushing.Original crane hydraulic system comprises hydraulic oil container 1, oil hydraulic pump 7, transfer case 8, diesel engine 9, flushing feed circuit 10 and leaks drainback passage 11.
Earlier with the hydraulic oil in the heater 2 heating hydraulic oil containers 1, oiling valve of opening 3 and outlet valve 4, starting washing solution press pump 5,5 pressurizations enter flushing feed circuit 10 to the deep fat of hydraulic oil container 1 through the washing solution press pump, inject the pump housing of each oil hydraulic pump 7, the cold oil in the pump housing is got back to hydraulic oil container through leaking drainback passage.The hydraulic oil that constantly heats in the hydraulic oil container 1 circulates heating up to the temperature that reaches expection between hydraulic oil container 1 and oil hydraulic pump 7.
