Description
Technical field
The utility model relates to mechanical tensimeter, particularly relates to a kind of oil-filled pressure gauge that is applied to photoelectric type water pump controller.
Background technology
For photoelectric type water pump controller, conventionally its pressure detection is partly to adopt on pressure dial plate, to pacify 2 electronic type grooved optoelectronic switches, tensimeter is arranged on pipeline, when the pressure gauge crown changes by the effective coverage of optoelectronic switch Infrared correlation according to pipeline pressure, Infrared can be sent a level signal and process to single-chip microcomputer after being blocked by barrier, thereby has completed pressure detection; And for electronic type grooved photoelectricity, its work has response time restriction, if barrier is by the excessive velocities in its groove internal induction region, it can not send the level signal of variation, and require the sensed barrier area can not be too small, otherwise can not send the level signal of variation, also just can not complete the detection of pressure; For damping oil, there is the effects such as good buffering, damping in addition.The tensimeter that is applied in the market photoelectric type water pump controller all adopts common tensimeter, and major defect has: the one, and pressure gauge crown portion is tiny, completely the Infrared in shading light electric switch groove; Er Shi machine mandrel place does not add damping oil, make to rotate through soon because pipeline pressure changes the too fast tensimeter indicator that causes, faster than the response time of electronic type grooved optoelectronic switch, finally cause not detecting corresponding pressure signal, be subject in addition that the water hammer effect of water system affects, the tensimeter life-span is low etc.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, and a kind of high life is provided, simple in structure, and pressure is controlled convenient and is beneficial to automatic control, and induction light electric switch is sensitive, has the oil-filled pressure gauge of the photoelectric type water pump controller of buffering effect.
The technical scheme of the oil-filled pressure gauge of the utility model photoelectric type water pump controller is: it is characterized in that: comprise plastic meter shell and be arranged on the tensimeter assembly in plastic meter shell, described tensimeter assembly comprises copper sleeve, on copper sleeve, be equipped with dial plate, bourdon tube, gear drive and machine mandrel, described machine mandrel front end sets firmly the vertical indicator that is used to indicate pressure of Yi Yugai machine mandrel, a damping gear overlaps on rear end in described machine mandrel, damping gear is placed in lubricating cup, in lubricating cup, there is damping oil, on lubricating cup, be equipped with protective cover, together with covering with protective cover, lubricating cup rivets tightly on fixed support, fixed support connects dial plate, gear drive, bourdon tube and copper sleeve.
The utility model discloses a kind of oil-filled pressure gauge of photoelectric type water pump controller, by setting pressure table assembly in plastic meter shell, tensimeter assembly comprises and on copper sleeve, is equipped with dial plate, bourdon tube, gear drive and machine mandrel, a damping gear overlaps on rear end in described machine mandrel, damping gear is placed in lubricating cup, and damping oil is equipped with in lubricating cup the inside, has protective cover to cover and rivet tightly together on fixed support above lubricating cup, whole tensimeter utilizes screw to be arranged on pipeline, and its advantage has:
One, simple in structure, coordinate with electronic type grooved optoelectronic switch, pressure is controlled convenient, is beneficial to robotization and controls;
Two, compare with standard machinery tensimeter, induction light electric switch is sensitiveer, has buffering, cushioning effect, has reduced greatly because water system water hammer effect is to manometric damage, high life etc.
The oil-filled pressure gauge of photoelectric type water pump controller of the present utility model, weld mutually with gear drive one end of described bourdon tube, and the other end of bourdon tube welds mutually with copper sleeve, firm welding, assembling is reliable.Described copper sleeve afterbody place mounting O-shaped rings, has had O type circle, and good airproof performance when copper sleeve and water pipe assembling is water-tight.
Accompanying drawing explanation
Fig. 1 is the oil-filled pressure gauge structural representation of the utility model photoelectric type water pump controller;
Fig. 2 is that the oil-filled pressure gauge master of the utility model photoelectric type water pump controller looks schematic diagram.
Embodiment
The utility model relates to a kind of oil-filled pressure gauge of photoelectric type water pump controller, as Fig. 1, shown in Fig. 2, comprise plastic meter shell 1 and be arranged on the tensimeter assembly in plastic meter shell, described tensimeter assembly comprises copper sleeve 13, on copper sleeve 13, be equipped with dial plate 5, bourdon tube 2, gear drive 4 and machine mandrel 6, described machine mandrel 6 front ends set firmly the vertical indicator that is used to indicate pressure 3 of Yi Yugai machine mandrel, a damping gear 8 overlaps on 6 rear ends in described machine mandrel, damping gear 8 is placed in lubricating cup 7, in lubricating cup, there is damping oil 9, on lubricating cup 9, be equipped with protective cover 10, together with covering with protective cover 10, lubricating cup 9 rivets tightly on fixed support 11, fixed support 11 connects dial plate 5, gear drive 4, bourdon tube 2 and copper sleeve 13.The tensimeter of this programme is screwed on pipeline, when pipeline has hydraulic pressure, current enter bourdon tube 2 by copper sleeve 13, and it is opened, the gear drive 4 that drives bourdon tube 2 afterbodys to connect, also just further driven the machine mandrel 6 being connected with gear drive 4 other ends to rotate, thereby the indicator 3 that Shi Yu machine mandrel 6 connects rotates, and by the graduation indication force value on dial plate 5, machine mandrel rotates and also drives the damping gear 8 of lubricating cup 9 the insides to rotate in addition, damping gear 8 is arranged in lubricating cup 9, lubricating cup the inside has been full of damping oil 9, damping oil has buffering, the effect of damping, machine mandrel is rotated and become steady, slowly.And while being applied on photoelectric type water pump controller, electronic type grooved optoelectronic switch is positioned on manometric dial plate 5, and indicator 3 can freely pass through the Infrared correlation effective coverage of optoelectronic switch, in addition for electronic type optoelectronic switch, its work has response time restriction, require the speed of barrier by Infrared correlation effective coverage can not can not be too small faster than the area of its response time and barrier sensitive surface, must disposablely all block Infrared otherwise can not detected pressures signal, cause controlling and lost efficacy, and use this tensimeter can effectively solve the problem of above existence.Its advantage has: one, simple in structure, coordinate with electronic type grooved optoelectronic switch, and pressure is controlled convenient, is beneficial to robotization and controls.Two, compare with standard machinery tensimeter, induction light electric switch is sensitiveer, has buffering, cushioning effect, has reduced greatly because water system water hammer effect is to manometric damage, high life etc.
