Abstract
The utility model discloses a vacuum oil injection machine with an automatic oil level control function. The vacuum oil injection machine comprises an oil tank. An oil inlet pipe, a gear pump, an oil output pipe, a precision filter and a vacuum pump are sequentially arranged on the top of the oil tank, the oil inlet pipe, the gear pump, the oil outlet pipe and the vacuum pump are respectively communicated with the oil tank, and an oil injection switching device is arranged between the oil inlet pipe and the gear pump. The vacuum oil injection machine is characterized in that the oil tank is erected on a vehicle frame, rollers are arranged at the bottom of the vehicle frame, and a liquid level sensor is arranged on a pipeline of the oil inlet pipe and is connected with an electromagnetic valve of a switch of the oil inlet pipe. The vacuum oil injection machine has the advantages that when oil in the oil injection machine reaches a sensing position of the liquid level sensor, the electromagnetic valve, which is connected with the liquid level sensor, of the switch of the oil inlet pipe is switched off under the control of the liquid level sensor, and accordingly the purpose of automatically controlling oil levels can be achieved.
Description
Technical field
The utility model relates to a kind of vacuum oil-injecting machine, relates in particular to a kind of vacuum oil-injecting machine of automatic control oil level.
Background technology
In the use procedure of high-tension current inductor or voltage transformer, along with the variation in service time increase and season, the oil level of the insulation oil product in it has decline, needs regularly to its oiling out of doors.For this small amount of oiling, if adopt existing common oiling equipment from the pouring orifice oiling meeting of current transformer or voltage transformer bottom, oil to be contacted with air, easily produce bubble, make the air content in oil, water content increases, thereby the class of insulation of oil product is declined, go back and easily cause insulation fault when bubble enters between mutual inductor coil; And if carry out oiling from the open top of outdoor high-voltage instrument transformer, often need to have a power failure, when operation, must remove top cover, very trouble, and due to operation aloft, without secure support, has certain risk.
Therefore, developed at present vacuum oil-injecting machine to address the above problem, vacuum oil-injecting machine to vacuumizing in equipment, is now closed oil circuit by vacuum pump, then passes through oil pump smoothly to its oiling.Now vacuum line is closed in and vacuumizes the bubble that simultaneously can eliminate while oiling, and after oiling puts in place, then the gas vacuumizing in gas and the equipment coil of guaranteeing in equipment oil taken out, and has ensured the insulating properties of insulating oil.
But oiling machine needs artificial supervision in the process of oiling, loses time so very much and manpower and materials.
Summary of the invention
The utility model provides a kind of vacuum oil-injecting machine of automatic control oil level, and object is to solve prior art problem, provides a kind of safe and efficient, can automatically control the vacuum oil-injecting machine of oiling oil level.
The utility model deal with problems adopt technical scheme be:
A kind of vacuum oil-injecting machine of automatic control oil level, there is oil tank, the top of oil tank is provided with oil inlet pipe, gear pump, flowline, accurate filter and vacuum pump successively, described oil inlet pipe, gear pump, flowline, vacuum pump are communicated with oil tank respectively, between described oil inlet pipe and gear pump, be provided with oiling conversion equipment, it is characterized in that: described tank rack is located on vehicle frame, the bottom of vehicle frame is provided with roller, on the pipeline of oil inlet pipe, be provided with level sensor, level sensor is connected with the electromagnetically operated valve of the switch of oil inlet pipe.
The beneficial effects of the utility model: because the utility model is provided with level sensor, in the time that the fluid in oiling machine reaches the position of level sensor induction, the closed electromagnetic valve of the switch of the oil inlet pipe that level sensor control is attached thereto, realizes the object of automatically controlling oil level.

In figure: 1, oil tank; 2, oil inlet pipe; 3, gear pump; 4, flowline; 5, accurate filter; 6, vacuum pump; 7, vehicle frame; 8, roller; 9, level sensor.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of vacuum oil-injecting machine of automatic control oil level as shown in Figure 1, there is oil tank 1, the top of oil tank 1 is provided with oil inlet pipe 2 successively, gear pump 3, flowline 4, accurate filter 5 and vacuum pump 6, described oil inlet pipe 2, gear pump 3, flowline 4, vacuum pump 6 is communicated with oil tank 1 respectively, between described oil inlet pipe 2 and gear pump 3, be provided with oiling conversion equipment, described oil tank 1 is erected on vehicle frame 7, the bottom of vehicle frame 7 is provided with roller 8, on the pipeline of oil inlet pipe 2, be provided with level sensor 9, level sensor 9 is connected with the electromagnetically operated valve of the switch of oil inlet pipe 2, in the time that the fluid in oiling machine reaches the position that level sensor 9 responds to, level sensor 9 is controlled the closed electromagnetic valve of the switch of the oil inlet pipe 2 being attached thereto, realize the object of automatically controlling oil level.
The vacuum oil-injecting machine of the present embodiment is mainly used in to oil-filled transformer, and current transformer injects insulating oil, also can be for oiling operations such as 110-550KV transformer, conduit, loaded switchs.
The feature of the present embodiment: first with vacuum pump, the metal expander top above instrument transformer is extracted into after high vacuum, insulating oil can arrive the required normal oil level of equipment by oil pipe bottom automatic oiling or by oil pump oiling.Its advantage be residual gas in oil-filled equipment particularly the gas between coil first dividend take out, equipment refuels, makeup oil convenience, safety, oil are not polluted, and the original insulation property of energy guarantee equipment are that vast power test overhauls the instrument that department welcomes.
In the process of oiling, first by oil-in 2 and gear pump 3 to the interior oiling of oil tank 1 in the time that the fluid in oil tank 1 reaches the position that level sensor 9 responds to, level sensor 9 is controlled the closed electromagnetic valve of the switch of the oil inlet pipe 2 being attached thereto, after filling oil, move near the equipment that needs oiling filling oily oil tank 1, by flowline 4 and the equipment connection that needs oiling, and by vacuum pump 6, air is extracted out, make equipment in high vacuum state, then open the oiling device that flowline 4 is provided with, start to needing oiling in the equipment of oiling, when the oil level in the equipment that needs oiling reaches behind normal position, the equipment that needs oiling is vacuumized, object is that the bubble in equipment is taken out, make equipment cavity zone in vacuum state.
For making any technical staff in this area realize or to use the utility model, above disclosed embodiment is described.To those skilled in the art; The various alter modes of these embodiment are all apparent, and General Principle defined herein also can be applicable to other embodiment on the basis that does not depart from spirit of the present disclosure and protection range.Therefore, the embodiment that the disclosure is not limited to provide herein, but consistent with the widest scope of the disclosed principle of the application and novel features.
