Description
Technical Field
The utility model relates to a turbo expander is with oil supply unit of oil pump oil leakage that turbo expander used.
Background
The turboexpander is a key single machine in the air separation equipment, provides almost all cold energy in the air separation equipment, and directly determines the energy consumption and the reliability of the air separation equipment by the performance of the turboexpander; at present, in air separation equipment, most matched turboexpanders are lubricated by oil bearings, and the turboexpanders have the advantages of convenience in operation, stability in operation, large bearing capacity and suitability for operation under various working conditions.
The oil supply device generally comprises an oil pump, an oil tank, an oil inlet filter, a one-way valve, a safety valve, an oil-water cooler, a double-barrel oil filter, an energy accumulator, an oil return observer, an oil-gas separator, an electric heater, a valve and the like; the oil pump is a key part, and the oil pump can continuously and stably run during the long-term running process of the oil supply device, does not have noise exceeding the national standard, and particularly has no obvious oil leakage phenomenon at the place where the oil pump is contacted with air; especially, the national places pay more and more attention to environmental protection and put forward higher requirements on the discharge of industrial liquid, so how to recover lubricating oil leaked from an oil pump becomes a problem to be solved urgently at present.
The oil pump of the existing oil supply device adopts a gear pump, but the gear pump has the problems of unbalanced radial force, large flow pulsation, large noise, low efficiency and serious leakage of lubricating oil during operation; the pump has the great disadvantage that mechanical sealing is adopted at the connecting part of the motor and the screw coupling, zero leakage cannot be realized, and particularly, when the coupling is poor in processing and assembling quality, the oil leakage phenomenon occurs just after the horizontal three-screw pump starts to operate, and the field environment is polluted.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art and providing a fuel feeding unit that turbo expander used oil pump does not leak oil.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an oil-tight oil supply device of an oil pump for a turbo expander comprises the oil pump and an oil tank; the oil pump is connected with the motor through a coupler; the oil pump and the coupler are both arranged in the oil tank.
Preferably, the oil pump is a vertical three-screw pump.
Preferably, a connecting plate is arranged above the joint of the coupler and the motor and connected with a panel of the oil tank, and the vertical three-screw pump and the coupler are arranged in the oil tank together; the motor is vertically arranged at the upper end of the oil tank.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the oil supply device for the oil pump for the turboexpander, which is disclosed by the utility model, has the advantages that the vertical three-screw pump and the shaft coupling are arranged in the oil tank together, so that the oil absorption effect of the vertical three-screw pump is better, the oil leakage phenomenon of the oil pump is thoroughly solved, the pollution to the environment is eliminated, the purposes of energy conservation, emission reduction and environmental protection are achieved, and the competitiveness of products is improved; meanwhile, actual inspection proves that: about 50 liters of oil can be recovered in one month, 600 liters can be recovered in one year, the value is about 3 ten thousand yuan, and the use cost is saved.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic view of an oil supply device of the present invention, in which an oil pump does not leak;
FIG. 2 is an enlarged schematic view of a vertical three-screw pump of the oil supply device of the present invention;
wherein: 1. a vertical three-screw pump; 2. a motor; 3. an oil tank; 4. a coupling; 5. a connecting plate; 6. an oil inlet; 7. an oil outlet pipe.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-2, the oil-tight oil supply device of the oil pump for the turbo expander of the present invention includes a vertical three-screw pump 1, a motor 2, an oil tank 3, an oil inlet filter, a check valve, a safety valve, an oil-water cooler, a dual-cylinder oil filter, an energy accumulator, an oil return observer, an oil-gas separator, an electric heater, a valve, etc.; the vertical three-screw pump 1 is connected with the motor 2 through a coupler 4; the vertical three-screw pump 1 and the coupler 4 are arranged in the oil tank 3, and the motor 2 is vertically arranged at the upper end of the oil tank 3, and the specific method is that a connecting plate 5 is arranged above the joint of the coupler 4 and the motor 2, the connecting plate 5 is connected with a panel of the oil tank 3, and the vertical three-screw pump 1 and the coupler 4 are arranged in the oil tank together; the vertical three-screw pump 1 is immersed in lubricating oil, so that the lubricating effect is good, the condition that the lubricating oil cannot be sucked is avoided, and the lubricating oil cannot leak because the coupling 4 is positioned in the oil tank; simultaneously the utility model discloses all adopt flange and welded connection between each part, all not have the oil leak phenomenon between all parts.
When the vertical three-screw pump is used, lubricating oil is sucked from the oil inlet 6 by the vertical three-screw pump 1 and then supplied to the turboexpander through the oil outlet pipe 7 for use, the vertical three-screw pump 1 is immersed in the lubricating oil, so that the lubricating effect is good, the condition that the lubricating oil cannot be sucked is avoided, and the coupler 4 is positioned inside the oil tank, so that the lubricating oil cannot leak even if the oil seeps from the coupler 4 and still flows into the oil tank 3.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the oil supply device for the oil pump for the turboexpander, which is disclosed by the utility model, has the advantages that the vertical three-screw pump 1 and the shaft coupling 4 are arranged in the oil tank together, so that the oil absorption effect of the vertical three-screw pump 1 is better, the oil leakage phenomenon of the oil pump is thoroughly solved, the pollution to the environment is eliminated, the purposes of energy conservation, emission reduction and environmental protection are achieved, and the competitiveness of the product is improved; meanwhile, actual inspection proves that: about 50 liters of oil can be recovered in one month, 600 liters can be recovered in one year, the value is about 3 ten thousand yuan, and the use cost is saved.
