Abstract
The utility model discloses a mine hoisting machine constant temperature hydraulic station, belongs to hydraulic stations, and aims at providing a hydraulic station which can automatically adjust and control the temperature of pressure oil. The mine hoisting machine constant temperature hydraulic station comprises an oil tank, and a motor, an overflow valve, a pressure meter, a high pressure filter, an energy accumulator and a pile-up valve group which are fixed on the oil tank, an oil pump which is arranged in the oil tank and connected with the motor, a filter which is connected with the oil pump, and a temperature senor (8) which is fixed on the oil tank (12) and is electrically connected with the PLC, wherein an electric heater (11) which is electrically connected with the PLC is arranged in the oil tank (12), and a cooling system (1) which is electrically connected with the PLC is communicated with the oil tank (12) through an oil inlet pipe (13) and an oil return pipe (14). The mine hoisting machine constant temperature hydraulic station can control the working oil temperature to be kept in the preset range, guarantees normal work of braking systems, and improves the safety reliability of mine lifting machines.
Description
Technical field: the utility model relates to a kind of hydraulic station, relates in particular to a kind of constant temperature hydraulic station.
Background technique: well-known, in the heavy mechanical equipment hydraulic system temperature of pressure oil whether normally will be directly connected to entire equipment can safe operation; The rising of pressure oil temperature can make the viscosity of fluid descend, and not only can cause the flow velocity of pressure oil to change, but also understand the wearing and tearing of acceleration equipment, thereby influence the normal operation of equipment.Hydraulic station is the key equipment of mine hoist braking system, yet the hydraulic station of traditional mine hoist does not generally have the thermostatically control function, and the temperature fluctuation of pressure oil is bigger, and therefore the braking system of mine hoist exists bigger potential safety hazard at present.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aim to provide a kind of can to the pressure oil temperature automatically adjust control mine hoist constant temperature hydraulic station.
To achieve these goals, the utility model is by the following technical solutions: it comprises by fuel tank, be fixed on motor, relief valve, pressure gauge, high pressure filter, accumulator and integrated valve group on the fuel tank, be arranged on oil pump that is connected with motor in the fuel tank and the filter that is connected with this oil pump; Be provided with the electric heater that is electrically connected with PLC in the fuel tank, be fixed on the temperature transducer that is electrically connected with described PLC on the fuel tank; The cooling system that is electrically connected with PLC is communicated with fuel tank by oil inlet pipe, return tube.
Fuel tank is provided with level meter; The bottom of fuel tank is provided with anti-oilhole.
Compared with the prior art, the utility model is owing to adopted technique scheme, cooling system, temperature transducer and electric heater on the basis at conventional hydraulic station, have been increased by PLC control, therefore can the Control work oil temperature maintain predetermined scope all the time, thereby guaranteed that braking system can work safely normally, improved the safety reliability of mine hoist.
