Abstract
This utility model relates to a kind of 600MW unit low oil pressure test device, it includes low oil pressure switch, Pressure gauge, isolating valve and relief valve, one end of isolating valve connects low oil pressure switch, the other end of isolating valve connects oil feed line, being provided with Pressure gauge and relief valve between isolating valve and low oil pressure switch, the lower section of relief valve arranges fuel tank.Operations staff can by pressure switch action time, Pressure gauge numerical value records accurately, and small investment effect is big, has established solid foundation for the little machine of unit safe and stable operation from now on.
Description
Technical field
This utility model relates to a kind of low oil pressure test device, particularly relates to a kind of 600MW unit low oil pressure test device.
Background technology
600MW supercritical unit, the low oil pressure test of equipment is currently and is carried out test pressure switch by thermal technology personnel
Short circuit, inspection pressure switch whether action, can emergency bearing oil pump normally join and open, although it is standby to utilize this test method to check
Can oil pump normally join and open, but can not monitor the concrete numerical value of pressure switch action.And 600MW unit reserve oil pump can not
Connection opens in time, it is possible to cause the tripping operation of little machine to cause unit RB load shedding event.
Utility model content
This utility model is for above-mentioned problems of the prior art, it is provided that a kind of 600MW unit low oil pressure test
Device, the problem solving the concrete numerical value that can not monitor pressure switch action in prior art.
The technical solution of the utility model is as follows:
Including low oil pressure switch, Pressure gauge, isolating valve and relief valve, one end of isolating valve connects low oil pressure switch, isolation
The other end of valve connects oil feed line, is provided with Pressure gauge and relief valve, the lower section of relief valve between isolating valve and low oil pressure switch
Fuel tank is set.
It is provided with high-pressure ball valve between described isolating valve and Pressure gauge.
Described fuel tank passes sequentially through return filter, oil return stop valve, check valve connect with oil feed line.
The utility model has the advantages of as follows:
Operations staff can by pressure switch action time, Pressure gauge numerical value records accurately, and small investment effect is big, for
The little machine of unit safe and stable operation from now on has established solid foundation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, isolating valve, 2, relief valve, 3, high-pressure ball valve, 4, return filter, 5, oil return stop valve, 6, check valve,
7, oil feed line, 8, fuel tank, K, low oil pressure switch, P, Pressure gauge.
Detailed description of the invention
Embodiment
As it is shown in figure 1, include low oil pressure switch K, Pressure gauge P, isolating valve 1 and relief valve 2, one end of isolating valve 1 connects
Low oil pressure switch K, the other end of isolating valve 1 connects oil feed line 7, is provided with Pressure gauge P between isolating valve 1 and low oil pressure switch K
With relief valve 2, being provided with high-pressure ball valve 3 between isolating valve 1 and Pressure gauge P, high-pressure ball valve regulates for pressure；Relief valve 2 times
Side arranges fuel tank 8, and fuel tank 8 passes sequentially through return filter 4, oil return stop valve 5, check valve 6 connect with oil feed line 7.
Being first shut off isolating valve, the most slowly open gate gurgle valve, when oil pressure is down to action numerical value, test pressure is just switching
Often action, emergency bearing oil pump joins in time and opens, operations staff can by pressure switch action time, Pressure gauge numerical value is recorded accurately
Come.The oil that fuel tank reclaims, sends oil feed line back to by return filter, oil return stop valve, check valve, recycles.
The above is specific embodiment of the utility model and the know-why used, any based on this utility model
Equivalent transformation on the basis of technical scheme, within belonging to protection domain of the present utility model.
