Abstract
The utility model discloses a steam turbine oil quality monitoring apparatus which comprises four signal monitors connected in parallel through an inlet and an outlet pipelines and a group of controlling valves, wherein, each monitor in the shape of a cylinder is divided into a cover and a shell. The top of the cover is transparent, and the interlayer of an oil transportation plate is arranged between the cover and the shell. Signal paper with colour codes is arranged on the oil transportation plate. The steam turbine oil quality monitoring apparatus with easy use and electric power reduction provides a scientific managing method for monitoring oil quality and providing helps for safe operation.
Description
The utility model is a steam turbine with a kind of oily surveillance device that monitors oily impure situation in the oil system by colour code.
No matter being homemade at present or the steam turbine of keeping away mouthful, whether need purify, two kinds of methods are arranged if differentiating oil, and 1, be sample examination; 2, be to infer oily time of on steam turbine, using and the time that in the past purifies consumption rule determine to purify once more when carry out.Sample examination can only do oil flash-point, kinematical viscosity and the test of antiacid degree, what degree the impurity content that suspends in the oil reached do not have definite standard; Determine oily poor accuracy with experience in addition.Because of oil does not meet loss that standard causes generally all about 10,000 yuan, change bearing loss because of oily problem causes as No. 1 machine of Shaanxi Cheng Cheng county power plant and reach and pick up 20,000 yuan.
To be that specialized designs is a kind of is connected with valve and the surveillance device that constitutes through piping by four identical monitor units of structure the purpose of this utility model, clear and significantly demonstrate oily situation by colour code.
The utility model is to realize with following technical proposal: it by four identical picture monitors of structure by pipeline and one group of stopcock and connect and constitute, wherein each monitor unit is divided into cover and housing two-part, the top of cover is a glass cover, it is by the pressure ring reinforcing that is threaded with cover, housing top is provided with the oil transportation plate, place a signal paper that has a colour code thereon, housing left and right side and bottom are respectively equipped with the oil-feed mouth of pipe, exhaust pipe mouth and oil drainage hole, and cover becomes an integral body with the housing scyewed joint.
Advantage of the present utility model: this device is installed in steam turbine with in the oil system, steam turbine oil can be through the monitor unit of channel flow in this device, because be provided with colour code paper in the monitor unit, the quantifiable form of dirty situation of oil shows, colour code is different, so showing oily degree of fouling also can show, allow administrative staff know the dirty situation of steam turbine oil that certain machine uses intuitively with the notion of range estimation mode and consumption by the photoscope on the cover, for oil is selected a treatment and purification time the most appropriate, avoid purifying unrestrained disabled person's power energy or hysteresis clean oil in advance and cause damage, and offer help for safe operation to steam turbine.
Description of drawings of the present utility model:
Fig. 1 is the utility model single unit system connection diagram.
Fig. 2 is the utility model monitor unit A-A sectional drawing.
Fig. 3 is the signal paper schematic representation that has colour code.
In conjunction with Figure of description 1-3 overall structure of the present utility model and use principle thereof are described further:
As shown in Figure 1: four monitor unit I, II, III, IV that same structure is arranged, the left side of each monitor unit is connected to segmentation oil inlet pipe 3, every segmentation oil inlet pipe is communicated with threeway plug valve 9,11,13 respectively, and each threeway plug valve all is connected on the main oil inlet pipe 15; The left side of four monitor units is connected to segmentation outlet pipe 4 respectively, and every outlet pipe is connected with straight-through cock valve 8,10,12,14 respectively, and throughway valve is connected with exhaust main pipe 17 respectively; The bottom of monitor unit I, II, III, IV is provided with oil drainage hole 7, oil drainage hole with insert oil extraction main pipe 16 again after throughway valve links to each other.The internal structure of each supervision is like this, and as shown in Figure 2: monitor unit is divided into cover and shell two large divisions, and covering 24 tops is glass cover, and this glass cover is threaded with cover 24 by pressure ring 23 and is fixed; Housing 25 tops are provided with oil transportation plate 26, place a signal paper 5 that has a colour code thereon, and cover 24 and housing 25 are one with the scyewed joint.As shown in Figure 3, the signal paper that has colour code is a kind of filter paper of white, 0,1,2,3,4,5 six numeral of regulation is arranged as the colour code number on the filter paper, and each digital tone depth difference is called colour code to them.
The working procedure of this device is like this, monitored oil when pump enters main oil pipe road 15 at first through control valve 19, modulating valve 20, oil pressure is set up at every square centimeter 3 MPa pressure, and with the flow of 1～3 liter of per minute to the monitor unit fuel feeding, through main oil pipe 15, again through threeway plug valve 13,11,9 flow into segmentation transport pipe 3, enter monitor unit oil transportation mouth 22, enter accumulator 1 from the following breach of pressure ring 23, air under the pressure of oil in accumulator 1 and the accumulator 2 is driven and is discharged from pressure ring upper air vent 4, through stopcock 8 (at this moment stopcock 8 is answered half-twist) discharge conduit 17.At this moment spy on from the monitor unit glass roof.If in the time of can only discerning 5 words on the colour code paper, oil should be judged to be 4 grades of oil, oil require purified treatment on request, start tracking at decontamination process II monitor unit, its process is at first to remove the I monitor unit, left- hand rotation stopcock 8 and 9, make pressure oil enter II monitor unit accumulator 1 through stopcock 9, equally, after air is discharged, spy on colour code in the II monitor unit by glass cover, levoversion valve 10 then, make oil flow to lubricant pipe 16, also do not continuing purification if oil reaches the use standard through oil drainage hole 7, opening III monitor unit tracking survey so looks, at first remove the II monitor unit, finish until the monitoring of IV monitor unit input like this, all processes is to need finish in 72 hours, after purify finishing, should be able to see that on the colour code paper of IV monitor unit " 1 " or " 2 " word can think qualified.Closed control valve 18,19 stops to monitor then.
