Abstract
The utility model relates to an oil lens for an air compressor with an oil starvation protector, which comprises a shell of the oil lens, a liquid level sensor and an adjusting screw of the liquid level sensor. The liquid level sensor is used for detecting the height of the liquid level in the oil lens, outputting a signal, and realizing the alarm and the power-off protection of the air compressor by an external circuit. The oil lens is provided with an oil hole and an air pressure balancing hole, and engine oil can be automatically injected into a crank case when the liquid level sensor outputs a control signal, so that the liquid level of the engine oil can be kept within a stated range at any time. The oil lens for the air compressor with the oil starvation protector can be directly arranged at the position of the oil lens of the existing air compressor, and any structures of the existing air compressor can not be changed, so that the oil lens has the advantages that the structure is simple, small and light, the installation and the change are convenient, and the cost is low; therefore, the oil lens is extremely convenient to be popularized in the industry.
Description
Technical field
The utility model relates to a kind of used for air compressor oil mirror with the oil starvation protective gear, belongs to air compressor oil starvation protection equipment technical field.
Background technique
(be called for short: be a kind of engineering machinery commonly used air compressor), its working principle is by pistons reciprocating to air compressor, produces certain air pressure.Because piston need be reciprocating during working state, lubricates so need lubricant oil in the cylinder block.Existing air compressor crank box outer wall all is equipped with an oily mirror, oil mirror one end is connected with crankcase with sealing gasket by screw, the oil mirror the other end has a glassy peep hole, is used to allow the user observe what of cylinder interior lubricating oil, and whether decision adds lubricant oil.But actual air compressor all be placed on outdoor, noise is big, surrounding environment is poor, can not the personal management, the user usually forgets and observes what of lubricant oil in the cylinder body under the working state, causes oil starvation and burns out the air compressor piston/cylinder and draw faults such as bad, that bent axle is locked, hundred yuan at least of its maintenance expensess, thousand yuan at most, not only influence is used, and also operating irregularity can occur.The using light electric transducer detects the patent of the oil level of fuel tank internal in the industry, but air compressor inside (particularly piston type air compressor) high temperature, mist of oil splashes, and the sensor light photosensitive elements is very fast to be covered by greasy dirt, and it is undesirable to detect effect.
Summary of the invention
The purpose of this utility model is overcoming the shortcoming of prior art; invent a kind of used for air compressor oil mirror with the oil starvation protective gear; it is directly installed on the oily mirror position of existing air compressor; the oil level that detects oily mirror inside by liquid level sensor changes, passes through oil hole, air equalizer opening and control circuit acting in conjunction, and air compressor is protected.
Structure of the present utility model is: an end outer wall of the used for air compressor oil mirror of band oil starvation protective gear has to connect uses screw thread (or flange); be used for linking with the air compressor crank box outer wall; the other end termination of used for air compressor oil mirror has a peep hole; the Glass optical lenses (9) that is used to observe is housed on the peep hole; it is characterized in that on shell (4) peripheral wall of used for air compressor oil mirror, having a hole; a liquid level sensor (6) is housed in the hole, and liquid level sensor (6) is connected with control circuit by cable (7).
Shell peripheral wall upper position at used for air compressor oil mirror has an air equalizer opening (8), also has a tank filler sleeve (10) at the shell peripheral wall lower position of used for air compressor oil mirror.
Tank filler sleeve (10)) connects with miniature oil pump (11) through oil outlet tube (12), miniature oil pump (11) is by pipeline and leakproof fuel cell (15) UNICOM, barometric pipe (13) is arranged at leakproof fuel cell (15) top, barometric pipe (13) connects with air equalizer opening (8), and a fuel tank cap (14) is arranged at leakproof fuel cell (15) top.
Air equalizer opening (8) and tank filler sleeve (10) can be respectively with bolt seal.
The oil mirror is installed in air compressor crank box outer wall (comprising position, oily mirror hole).
Liquid level sensor (6) is that except that photocurrent sensor other can detect the sensor or the switch of liquid level change.
Working principle is: the utility model only will have the oily mirror size lengthening of air compressor now, open a hole in oily mirror outer circumferential walls, and adorn a liquid level sensor (6), measure the liquid level change of oily mirror inside by liquid level sensor (6), obtained crankcase inner engine oil liquid level height data indirectly,, manually or automatically controlled adding machine oil quantity and opportunity by the switching element of control circuit, guarantee that the air compressor inner engine oil at any time all at the height of setting, prevents the air compressor oil starvation.
The used for air compressor oil mirror of the utility model band oil starvation protective gear has simple in structure; small volume and less weight; be convenient to install and change, cost is low, can be directly installed on the oily mirror position of existing air compressor; need not to change existing air compressor any structure; the air compressor petrol starvation takes place in the time of can effectively preventing to use, and reduces or avoids accident to take place, can automatic oiling; very being convenient to industry and promoting, is a kind of product with extensive market prospects.
