Abstract
The utility model provides a transformer oil vacuum filters system, includes vacuum pump, real empty can, the top is provided with the shower head in the real empty can, the shower head communicates with each other with the external world through the gear pump, the vacuum pump buffer tank and real empty can UNICOM pass through, the buffer tank on be provided with inlet tube and outlet pipe, the outlet pipe is located the inlet tube top, there is the cooling water coil pipe in the UNICOM between inlet tube and the outlet pipe, the buffer tank on still be provided with intake pipe and outlet duct, the intake pipe is located outlet duct top position, intake pipe and real empty can UNICOM, buffer tank circular arc die bed portion still is provided with the oil discharge outlet. The utility model discloses an increase the cooling water coil pipe in the buffer tank, have very strong cooling action to oil gas, make the oil gas cooling subside to the deposit obviously reduces by the inspiratory oil gas volume of vacuum pump in the buffer tank, thereby reaches the purpose of protection vacuum pump.
Description
Technical field
The utility model relates to electric power electric oil-filled equipment house transformer oil filtration technology, relates in particular to a kind of transformer oil vacuum filtering system.
Background technique
Transformer oil is under the effect of heat, electric field, and oil contacts the various oxide of oxidized generation and alcohol, aldehyde, acid etc. gradually with oxygen, finally forms insoluble colloid, greasy filth Precipitation.These acidic materials reduce the insulating property of transformer, and therefore transformer oil must filtration treatment.
Vacuum pump is the indispensable important composition parts of transformer oil vacuum filtering system, and it can ensure that fluid is not secondary polluted, and guarantees that system works under being in a pole lowpressure state simultaneously.But in real operation, the oil gas in vacuum tank is often taken directly in vacuum pump, causes vacuum pump to damage.
In transformer oil vacuum filtering system, in order between vacuum pumping system and vacuum tank, avoid oil gas to be taken directly vacuum pumping system, be generally all provided with several knock out drums, reach the effect of buffering oil removing.
But the type of cooling of the knock out drum in current vacuum filtering system is air-cooled or naturally cools, and cooling effect is not good.Oil gas can be taken directly vacuum pumping system, enters vacuum pump.Due to very low (the < 12mm of transformer oil viscosity
2/ s), after entering the lubrication system of vacuum pump, vacuum pump lubricating oil viscosity can be made obviously to reduce, do not have lubrication effect, cause vacuum pump to damage.
Summary of the invention
The purpose of this utility model is to design a kind of buffer tank device having very strong cooling action; make it have good oil gas cooling effect, make the oil gas condensation of extraction, and be deposited in knock out drum; the oil and gas content that obvious minimizing is sucked by extract system, reaches the object of protection vacuum pump.
Technical problem to be solved in the utility model realizes by the following technical solutions: a kind of transformer oil vacuum filtering system, comprise vacuum pump, vacuum tank, in described vacuum tank, top is provided with spraying head, described spraying head is communicated with the external world by gear pump, described vacuum pump is by knock out drum and vacuum tank UNICOM, described knock out drum is provided with intake pipe and outlet pipe, described outlet pipe is positioned at above intake pipe, cooling water coil is linked with between described intake pipe and outlet pipe, described described knock out drum is also provided with suction tude and steam outlet pipe, described suction tude is positioned at steam outlet pipe top position, described suction tude and vacuum tank UNICOM, also fuel outlet is provided with bottom described knock out drum circular arc type.
The utility model, by increasing cooling water coil in knock out drum, has very strong cooling action to oil gas, makes oil gas cooling-sedimentation, and be deposited in knock out drum, obviously reduce the oil and gas content sucked by vacuum pump, thus reaches the object of protection vacuum pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of knock out drum in the utility model.
In figure 1, vacuum pump 2, knock out drum 3, gear pump 4, spraying head 5, vacuum tank 6, packing layer 7, suction tude 8, intake pipe 9, fuel outlet 10, steam outlet pipe, 11 cooling water coils 12, outlet pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
A kind of transformer oil vacuum filtering system, comprise vacuum pump 1, vacuum tank 5, in described vacuum tank 5, top is provided with spraying head 4, described spraying head 4 is communicated with the external world by gear pump 3, it is characterized in that: described vacuum pump 1 is by knock out drum 2 and vacuum tank 5 UNICOM, described knock out drum 2 is provided with intake pipe 8 and outlet pipe 12, described outlet pipe 12 is positioned at above intake pipe 8, cooling water coil 11 is linked with between described intake pipe 8 and outlet pipe 12, described described knock out drum 2 is also provided with suction tude 7 and steam outlet pipe 10, described suction tude 7 is positioned at steam outlet pipe 10 top position, described suction tude 7 and vacuum tank 5 UNICOM, fuel outlet 9 is also provided with bottom described knock out drum 2 circular arc type.
Described vacuum tank 5 neutral position is provided with packing layer 6.
Above-described embodiment of the present utility model; it is only the citing clearly illustrating that the utility model does; but be not used for limiting protection domain of the present utility model; all equivalent technological schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by every claim.
