Abstract

The utility model relates to a monitor for flowing lubricating oil. The utility model is characterized in that a long shaft passes through a casing and an electric control box; a baffle plate, a cam and a pointer are fixedly installed on the utility model; a contact control signal circuit of a microswitch is extruded by the cam, and the contact control signal circuit can be reset by a pressing spring. The visual monitoring of a lubricating system is realized by a signal lamp and the pointer, and the cam can be regulated to control the alarm occasion according to the condition of flow demand. When the utility model is used, the timely and reliable monitoring is realized, the safe operation of the lubricating system of a large-sized machine can be guaranteed, and the accident is avoided. The utility model is particularly suitable for the lubricating monitoring of mine, metallurgy, power generation and other large-sized machines.

Description

The flow of lubricant monitoring unit

The utility model belongs to a kind of equipment lubrication flow system flow monitoring unit.

In the lubrication system of heavy duty equipment, particularly the monitoring alarm of main equipment lubrication systems such as metallurgy, mine, petrochemical industry to the maintenance management of equipment, guarantees that the normal operation of safety has crucial status.At present, China mainly uses YXQ type oil stream advertiser, and permanent magnet baffle plate and dry type tongue spring tube contact are arranged in the housing of advertiser, and permanent magnet easily makes the dry type tongue spring tube magnetization, and making original normally opened contact become normally-closed contact can not work.Especially the metal powder that is mingled with in the fluid is adsorbed on the permanent magnet, blocks baffle plate and can not rotate, and can not in time report to the police when oil starvation or oil-break in the system, seriously jeopardizes the safe operation of equipment.

The purpose of this utility model is to provide a kind of oil mass monitoring reliable, and signal is directly perceived, the flow of lubricant monitoring unit timely of reporting to the police.

Described flow of lubricant monitoring unit, comprise housing, major axis, baffle plate, electric control box, sensitive switch, pointer composition, it is characterized in that major axis connects housing and electric control box, fixing above by dress baffle plate, cam and pointer, contact control signal circuit on the cam extruding sensitive switch can be resetted by stage clip.Described cam is fan-shaped, by the corner that can limit baffle plate and pointer after the holding position fine setting.

The utility model has been cancelled permanent magnet and dry type tongue spring tube structure, has increased the pointer Direct box.The lubricant oil of certain pressure the time backs down baffle plate by inlet, and baffle plate, pointer and cam change an angle synchronously with major axis, cam extruding contact, and sensitive switch work, greensignal light is bright, and display system safety is normal.When oil pressure reduced, stage clip made the revolution of resetting property of major axis, and baffle openings diminishes, and cam loosens the contact, and sensitive switch makes the bright and warning circuit conducting warning of red eye.Monitoring accurately and timely, by oily condition in the intuitively reflection system of pointer, signaling lamp also directly shows oily condition, the more important thing is and to adjust cam position as required, to satisfy the alert if of different operating system, the control of realization secondary meter is fit to the monitoring of emphasis main equipment lubrication system, avoids the generation of major accident.

Fig. 1 the utility model sectional structure chart.Fig. 2 is Fig. 1 left view.Fig. 3 is that Fig. 1 plan view removes the loam cake situation.Fig. 4 is Fig. 1 plan view.

Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.

Please read Fig. 1, housing 10 half is cut protecgulum 14 positions open, and oil flows from import 12, interior import 11, baffle plate 16 to outlet 17.Baffle plate 16 is fixed on the major axis 15, is in the vertical position of import in opening.Major axis enters Direct box 4 through sealing gasket 18, bearing 19.Use nut compressing by dress stage clip 9, cam 8, pointer 3 successively on the major axis.Wherein, stage clip can make the major axis revolution drive interior import on the shutter, and contact 7, the sensitive switch 6 of cam extruding sensitive switch connect signaling lamp 21 (the left green right side is red) by lead 5 and in time report to the police.Seal ring 20 is used screw-driving with loam cake 1, and loam cake 1 has pointer scale dish 22.

Claims

1, a kind of flow of lubricant monitoring unit, comprise housing, major axis, baffle plate, electric control box, sensitive switch, pointer composition, it is characterized in that major axis connects housing and electric control box, fixing above by dress baffle plate, cam and pointer, contact control signal circuit on the cam extruding sensitive switch can be resetted by stage clip.

2,, it is characterized in that cam is fan-shaped, by the corner that can limit baffle plate and pointer after the holding position fine setting according to the described oily flow monitoring device of claim 1.
