Abstract
The utility model relates to a measuring meter for micro-flow oil, which is composed of a casing, an impeller box, an impeller, a magnetic coupling, a counter, a gear wheel box, an upper shell, a screw plug, a sealing ring, etc. The utility model is characterized in that the impeller forms a manufacturing method of chipless machining and a thin metal sheet structure. The utility model is used for measuring light oil quantity, and the impeller in light weight of the thin metal sheet structure ensures that the measuring meter measures oil quantity precisely when the lower limit of flowrate is 0.21/h.
Description
The utility model relates to a kind of micrometeor oil measurement instrument, belongs to the flow measurement technology field.
In the existing existing technology, adopting rotary wing flow table impeller all is to adopt the plastics pressing structure.Although plastics are in light weight, but intensity is low, limited by manufacture craft, impeller can not be done very thinly again (promptly can not be lighter), so that using of many now light fuel kitchen range and miniature gasoline engine is oily when low discharge, even when commonly used flow, all can not drive the wheel rotation of gauging table, so existing rotary wind type oil measurement table can not be used for measuring the oil mass of using of these kitchen range and miniature gasoline engine, thereby influence the reasonable fee of fuel oil company.
The purpose of this utility model is to improve impeller material, adopt metal sheet, alleviate impeller weight to greatest extent, and the long-term intensity of using of assurance, 1/10 of the not enough plastic impeller of impeller weight, thereby making oil measurement table lower limit measure flow is 0.2l/h, to the measuring requirement of fuel oil, good practicability is arranged when satisfying the gentle cylinder capacity of family expenses fuel oil kitchen range and be the small gasoline engine low-speed running about 50ml.
The utility model is made up of shell (1), impeller box (2), impeller (3), magnetic shaft coupling (4), counter (5), gearcase (6), upper casing (7), plug (8), O-ring seal parts such as (9).Referring to accompanying drawing.
The oil measurement table is installed on the pipeline, when flow of liquid is crossed the oil measurement table, its impeller (3) is rotated, and by magnetic shaft coupling (4) this rotation is passed to counter (5) in the gearcase (6) by the magnetic force in magnetic field again.Because the revolution of impeller is directly proportional with the flow of the liquid that flows through, therefore, the revolution of impeller is calculated through counter middle gear system, can on dial, demonstrate the total amount (1) that flows through liquid by pointer or character wheel.
The impeller of present embodiment adopts high strength, corrosion-resistant, metal sheet structure, makes through chipless working.
Claims (1)
1. micrometeor oil measurement table, form by shell (1), impeller box (2), impeller (3), magnetic shaft coupling (4), gearcase (5), counter (6), upper casing (7), plug (8), O-ring seal parts such as (9), it is characterized in that impeller (3) uses the metal sheet structure, make through chipless working.
