Abstract
The utility model relates to an air-cooling type high temperature resistant oil pump which is provided with a pump body, a pump seat, a mechanical seal, a bearing seat and a coupler which is connected with a motor. The utility model is characterized in that a fan is arranged on a pump shaft; a mechanical seal seat is connected with an oil inlet pipe and an oil outlet pipe, which are communicated with a cooling oil tank; an annular groove is arranged on the pump seat. The fan is rotated following the pump shaft, and the wind energy is generated to forcedly cool. Lubricating oil in the cooling oil tank can naturally circulate for cooling, and the annular groove can reduce the heat conduction to the motor. Therefore, when the utility model transports heat transfer oil for a long time, the motor is not heated, and the heat transfer oil of 350 DEG C can be transported.
Description
The utility model relates to a kind of pump, particularly relates to a kind of air-cooled high temperature resistant oil pump.
Existing high temperature resistant oil pump all adopts water-cooled, need add into, drainage equipment complex structure, price height.
The purpose of this utility model is to provide a kind of air-cooled high temperature resistant oil pump, and is simple in structure, can solve pump effectively and carry the athermic problem of conduction oil motor for a long time.
The purpose of this utility model is achieved in that the coupling 1 that is connected with motor is housed on the pump shaft 33, bearing 5 is installed on the axle 33 with bearing support 7, bearing (ball) cover 3 is installed at the two ends of bearing support 7, the mechanical seal of being made up of stationary ring 13, rotating ring 18, seal ring 14, throw-out collar 17 and spring 16 is contained on the axle 33, mechanical sealing base 12 1 ends are connected with pump seat 29, one end is equipped with end cap 11, pump seat 29 is contained on the axle 33 with axle sleeve 22, fix with the pump housing 26, and fix by connecting plate 20 and base 8.Impeller 23 is installed on the axle 33, and by rectification nut 25 it is tightened.The pump housing 26 is connected with pump seat 29.On the axle 33 fan 9 is installed, is fixedly connected with fan housing 10 on the bearing support 7.
The utility model technological scheme preferably is: on the basis of aforementioned schemes, on the mechanical sealing base mouth, be installed into oil pipe 31 and oil outlet tube 15, oil inlet pipe 31 and oil outlet tube 15 are communicated with the cooling fuel tank.
Best-of-breed technology scheme of the present utility model is: on the basis of aforementioned two technological schemes, pump seat 29 is provided with circular groove 30.
The utility model is owing to be equipped with fan on pump shaft, fan is in the back of mechanical sealing base, and fan rotates with pump shaft, and the wind of generation is forced cooling, and heat is passed on the motor less, makes pump carry for a long time that motor does not generate heat in the process of conduction oil.Again since on mechanical sealing base, be equipped with cool off that fuel tank is communicated with into and out of oil pipe, be full of lubricant oil in the cooling fuel tank, but the lubricant oil natural circulation cool off, also make a large amount of heats of conduction oil generation be difficult for drive motor.Pump seat is provided with a circular groove simultaneously, also makes heat be difficult for being transmitted on the motor, has solved pump and has carried the athermic problem of conduction oil motor for a long time.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional view according to the air-cooled high temperature resistant oil pump that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the air-cooled high temperature resistant oil pump that the utility model proposes.
