When at present the main motor shaft watt lubricating utensil of each boiler of power plant gas fan, induced draught fan, primary air fan repeatedly occurs in the gear pump switching tests, the stand by pump of the startup fault of not buying oil, and appear at simultaneously on the gear pump of new replacing.Each maintainer disintegrate gear pump and system pipeline, do not find to leak in gear pump motor counter-rotating, the check valve and the pipe wrong of coming in and going out etc. unusual, this defective was once occuring again and again, the safety in production situation of serious threat unit.
Oil system: oil system mainly is to utilize gear pump that power is provided, and by pipeline, check valve, throttle valve, safety valve, filter screen, pressure regulator valve pressure, the flow of lubricant oil is adjusted to suitable parameter, to satisfy the needs of bearing lubrication, system's adjusting.
Gear pump: a pair of pitch wheel and pumping cylinder separate suction chamber and discharge side.When gear rotated, the suction chamber side gear teeth mutually between cog volume of disengagement place increased gradually, pressure decreased, and liquid enters between cog under differential pressure action.Along with the rotation of gear, the liquid of between cog is taken to discharge side one by one.At this moment the between cog volume of discharge side side wheel tooth engagement place dwindles gradually, and liquid is discharged.Gear pump is applicable to carry and does not contain solid particle, non-corrosiveness, lubricating liquid that range of viscosities is larger.
The prior art shortcoming:
Gear pump is installed in (being that the gear pump body does not contact with oil) on the fuel tank free surface, the possibility of the shaft seal of gear pump, the oriented gear pump internal leakage of exhaust port air, after outside framework oil seal wearing and tearing to a certain degree, shaft sealing leakage becomes possibility, and gear pump the fault that gear pump is not bought oil will occur behind air amount.
The model utility content
The technical problems to be solved in the utility model provides a kind of blower fan oil system and installs the air-discharging device additional.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of blower fan oil system to install the air-discharging device additional, comprise filter screen, adjustable threeway, safety net, fuel tank, gear pump and one-way valve, it is characterized in that, also comprise emptier, described emptier one end connection teeth wheel delivery side of pump, the other end connects the one-way valve entrance; Described filter screen connects adjustable threeway, and described adjustable threeway connects one-way valve and safety net, and described safety net connects fuel tank, and described gear pump is installed on the fuel tank free surface.
Wherein, described emptier comprises emptying door and transparent hose, and described transparent hose is located at emptying behind the door end, and is inserted into below the fuel tank free surface.
Wherein, described transparent hose is inserted into the following 10-20mm of free surface.
Wherein, described emptying door adopts the needle type valve that can adjust flow.
Wherein, described emptying door is hold-open door.
The beneficial effect of technique scheme of the present utility model is as follows:
1, the emptier that installs additional in the such scheme is installed in the middle of gear pump outlet and the one-way valve entrance, has played preferably exhaust effect; The emptying door that installs additional simultaneously is the needle type valve valve that can adjust flow (pressure), can be easily the charge oil pressure of system be adjusted in the suitable scope; In addition, emptying door is hold-open door, after adjusting for the first time handwheel is taken down, and can prevent operation and maintainer's misoperation.
2, take in the such scheme to install a bypass emptier additional in the gear pump outlet, guarantee that the air in the gear pump initial start stage gear pump can be discharged smoothly, avoided stand by pump the phenomenon of not buying oil to occur, fundamentally improved the reliability and safety of equipment.
3, reasonable in design in the such scheme, the pipeline of oil system does not change, and is simple and reliable, invest little, successful; Greatly saved simultaneously the cost of repair time and purchase spare part; In addition, oil system has improved the reliability of equipment greatly as the main auxiliary equipment of fan operation, for the unit long-term operation provides guarantee.
