Abstract
The utility model relates to a lubricating oil-deficiency stopping device for electric air compressors, which floating body floating on the oil surface of lubricating oil in a small lubricating oil tank, a push rod, an upper electrode, an electrode frame, a lower electrode, an upper electrode conducting wire, and a lower electrode conducting wire. The utility model provides electric air compressors with a device which can automatically stop the electric air compressors when oil levels of lubricating oil in crank cases of the electric air compressors reach danger limit and avoids losses that crank shaft connecting rods are seized, connecting rods are broken off, and crank cases, cylinder sleeves and pistons are damaged, because lubricating oil in crank cases of electric air compressors is deficient. The utility model is particularly suitable for being used as a stopping device because of the deficiency of lubricating oil in crank cases for electric air compressors.
Description
The utility model relates to the mechanical ﹠ electrical technology field, the device that particularly a kind of lubricant level in the electric compressor crankcase can autostop during to danger limit.
Existing electric compressor is when the lubricant level in the crankcase during to danger limit, can not autostop, and can cause crankshaft-link rod to kill, connecting rod is fractureed, and crankcase, cylinder sleeve, piston are broken, and this can cause very big loss to the user.
Task of the present utility model is when the lubricant level in the crankcase during to danger limit at existing electric compressor; defective that can not autostop; the device of energy autostop when a kind of lubricant level in the electric compressor crankcase is provided to danger limit; avoid crankshaft-link rod to be killed; connecting rod is fractureed, and crankcase, cylinder sleeve, piston are broken.
Task of the present utility model is finished as follows: electric compressor lubricant oil oil starvation arresting gear is made up of buoyancy aid, push rod, little lubricating oil tank, transom, arc-spark stand, upper electrode lead, bottom electrode lead, containment vessel.Wherein, little lubricating oil tank is located at the bottom of crankcase, is provided with the through hole that communicates with little lubricating oil tank at crankcase bottom; Upper end at little lubricating oil tank is provided with jogger hole; On crankcase, be provided with transom, export department at transom is provided with oil baffle and dust board, to prevent that lubricant oil from entering in the crankcase with air-flow outflow and extraneous dust, air in the crankcase is communicated with ambient atmosphere, the pasta of the gas shock lubricant oil when avoiding air compressor when work piston up-down makes lubricant oil be in steady situation; Buoyancy aid floats on the pasta of lubricant oil of little lubricating oil tank, the lower end and the buoyancy aid of push rod are fixed, push rod passes jogger hole, the upper end of push rod is provided with lower insulation plate and bottom electrode, arc-spark stand is fixed on the crankcase, on arc-spark stand, be provided with upper insulation plate and upper electrode, upper electrode lead one is connected to upper electrode, the upper electrode lead the other end is connected on the end of the switching circuit of controlling motor, bottom electrode lead one is connected to bottom electrode, and the bottom electrode lead the other end is connected on the other end of the switching circuit of controlling motor.During use, when the oil level of the lubricant oil in the crankcase is in the top of minimum oil level line (under the oil mass normal state), the position of buoyancy aid that then is arranged in little lubricating oil tank is higher, at this moment the bottom electrode above the push rod on the buoyancy aid contacts with upper electrode, make the switching circuit conducting of control motor, electric motor normal working.When the lubricant oil in the crankcase consumes gradually along with the work of electric compressor, the buoyancy aid that then is arranged in little lubricating oil tank is also along with decline, when the oil level of the lubricant oil in the crankcase is in the below of minimum oil level line (when oil mass is in the danger limit state), bottom electrode and upper electrode above the push rod on the ball float are separated, cut off the switching circuit path of control motor, electric compressor is quit work, reach and avoid crankshaft-link rod to be killed, connecting rod is fractureed, the loss that crankcase, cylinder sleeve, piston are broken.
When the utility model provides a kind of lubricant level in the electric compressor crankcase to danger limit for electric compressor; the device of energy autostop; avoid being killed because of the lubricant oil oil starvation in the electric compressor crankcase causes crankshaft-link rod; connecting rod is fractureed, the loss that crankcase, cylinder sleeve, piston are broken.The utility model is particularly suitable as the crankcase lubricating oil oil starvation arresting gear of electric compressor.
