Said photoelectric subassembly 12 places and detects glass tube 7 stage casings; Infrared light power valve 15 of one side horizontal positioned; Become the position of 30 ° and 90 ° respectively to place a scattered infrared light receiving tube A17 and infrared light receiving tube B18 with infrared light power valve 15 axis in vertical direction, as shown in Figure 4.
Said cleaning brush 6 is provided with mounting hole 21 and horn-like water inlet 20, and said cleaning brush 6 is provided with coating, and is as shown in Figure 5.
Said controller housing 3 is provided with annulus convex surface 4, and said detection glass tube 7 places in the casing 14 with photoelectric subassembly 12, and casing 14 outsides are provided with Explosion-proof cap 11, and Explosion-proof cap 11 is connected with casing 14 through threaded flame-proof type face 13.
This device has structurally been done flame proof and the design of cleaning automatically, can be operated in the higher place of requirement of explosion proof, and oil concentration in the water is carried out automatic on-line detect, and the digital at the scene concentration that shows contained oil content in the water; Simultaneously remote data is sent to central control room, for management and control in real time provide foundation with 4-20mA standard interface mode.
The automatic cleaning of photoelectric sampler improves design, adopts pneumatic element to drive brush to-and-fro movement in detecting glass tube; The water hole of brush becomes waist shape, and it is horn-like that water inlet becomes, and makes current more unobstructed, steady, and silver plating process prevents growth activity mud on the brush.Lower-glass base one end becomes to be threaded with photoelectric subassembly, has improved the influence to accuracy of detection of appearance water and variation of ambient temperature; Photoelectric subassembly has increased the light receiving tube of 90 ° of configurations,
Can detect the turbidity of kind water, thereby improve the survey oil accuracy of instrument; Explosion-proof cap and housing adopt and are threaded, and the annular convex surface structure at threaded flame-proof type face top significantly improves the explosion insulation performance of housing.
This device is by controller housing 3, photoelectric sampler 1, and wiper mechanism 2 parts such as grade are formed.Shown in accompanying drawing 1.The sectional side view of controller housing 3 is shown in accompanying drawing 2.Its screw thread is isolated quick-fried top has an annulus convex surface 4.In the photoelectric sampler structural drawing 3,, cleaning is connected with the upper glass base 10 of photoelectric sampler 1 through blind nut 9 for providing the cylinder 5 of driving force; Clean brush 6 and be installed on the movable lug bar of cylinder 5, be placed in and detect in the glass tube 7, pump during cleaning; Photoelectric subassembly 12 combines with lower-glass base 8 through screw thread; Explosion-proof cap 11 combines with casing 14 with threaded flame-proof type face 13, and threaded top is the annulus convex surface, and the annulus convex surface has great role to the explosion insulation performance that improves instrument.Among photoelectric subassembly Fig. 4; Infrared light receiving tube A17 and another infrared light receiving tube B18; Because relative infrared light power valve 15 is residing position difference in the space, in instrument, plays a different role, and can when the appearance water turbidity is higher, accurately isolate the oil content signal thus.Temperature-sensing element (device) 16 is used to detect the variation of kind water and environment temperature among Fig. 4, for system carries out temperature compensation signal is provided.In addition, the screw thread 19 among Fig. 4 combines with the screw thread 22 of lower-glass base 8 among Fig. 7, can improve the temperature characterisitic of photoelectric sampler.The cleaning of online oil content appearance test chamber is a very important function; Maybe be but clean the existence of brush 6 in detecting glass tube 7 automatically to detecting deleterious impact, the mounting hole 21 that cleans among Fig. 5 on the brush has been got rid of this adverse effect preferably with the silver plating process of horn-like water inlet 20 structures and brush.
The principle of work of oil content monitor is in the online water: utilize infrared light when passing oil-containing water except transmitted light, also can produce the characteristic of scattering, designed a special photoelectric sampling thief.Photoelectric sampler mainly is made up of housing, glass tube, base, photoelectric tube assembly: glass tube passes the photoelectric tube assembly and vertically installs.Assembly places the glass tube stage casing, and infrared light power valve of a side horizontal positioned becomes the position of 30 ° and 90 ° respectively to place a scattered light receiving tube in vertical direction with launcher-tube line.When having oil-containing water to flow through in the glass tube, the output terminal that receives light pipe will produce the electric signal of oil concentration and water turbidity in the reflection water, and signal can directly reflect on display after amplifying, handling influences oil concentration and get rid of turbidity within the specific limits.The oil concentration data arrive central control room through the teletransmission circuit transmission simultaneously.
The use operating process is following: the oil content monitor is installed in the workplace that needs detection in the online water of flame-proof type, and the water system bypass that will monitor with T-valve and stainless-steel tube inserts photoelectric sampler.After the energized, instrument just detects automatically, and the display window of instrument shows the oil concentration value (with mg/L office) of monitored water sample automatically.The oil concentration value is with 4 simultaneously---and 20mA standard interface mode is sent to central control room to remote data.When oleaginousness surpasses limit value, warning circuit work, control signal can be controlled relevant device and start or stop.
Automatic cleaning mechanism cleans glass tube at official hour (by microprocessor control) every day, works 3 minutes at every turn.The teletransmission data are locked into " 00 " during the cleaning.
