Description
Technical field
The utility model belongs to oil-servicing facilities field, and in particular to electrically driven feed pump lubricating oil system.
Background technology
Electrically driven feed pump be fluid coupling motor-driven feed-water pump set, the pump group by fore pump, fluid coupling, motor, give
Water pump forms.Fore pump is directly driven by a motor, and feed pump is driven by motor by fluid coupling indirectly, and oil system is fluid power
Coupler feed pump important component, oil system are divided into lubricating oil and working oil two parts, and lubricating oil is for each bearing shell and liquid
Mechanical couple transmission gear provides lubricating oil, and working oil is to provide working oil for fluid coupling.
Fluid coupling electrically driven feed pump oil system is by fuel tank, main oil pump, auxiliary oil pump, overflow valve, lubricating oil cooling
Device, Working oil cooler, oil filter, oil pipe composition.Main oil pump is gear oil pump, is placed in fluid coupling babinet, feed pump
After startup, main oil pump operation is driven by transmission gear.Feed pump is before activation system fuel feeding by auxiliary oil pump.The fuel-displaced elder generation of oil pump
By overflow valve, then to oil cooler to oil filter, then it is divided into two-way, arrives lubricating oil main pipe all the way, is fore pump, motor, liquid
Each bearing shell of mechanical couple, feed pump and transmission gear provide lubricating oil, and according to lubricants capacity size, restricting orifice distributes each bearing shell
Lubricants capacity.Fluid coupling is arrived all the way, and working oil is provided for fluid coupling.After electrically driven feed pump starts, work as lubricating oil
When pressure is more than 0.3Mpa, stop auxiliary oil pump, starts auxiliary oil pump automatically when lubrication pressure is less than 0.08, work as lubricating oil
It forces down when 0.05, electrically driven feed pump tripping, lubricating oil pressure is derived from lubricating oil main-piping pressure.Pump side lubricating oil pressure is too low,
After switching strainer, pressure is without significant change.But find that lubricating oil pressure is low in the process of running, if sustainable development, pump
During operation, it may appear that the risk of oil-break tile kilning seriously affects the safe operation of electrically driven feed pump.
Utility model content
The utility model provides electrically driven feed pump lubricating oil system in order to solve the above technical problems, prevents the hair of oil-free tile kilning
It is raw, it is ensured that feed pump normal operation.
The technical solution of the utility model is：Electrically driven feed pump lubricating oil system, including fuel tank, feed pump, oil pump, auxiliary
Oil pump, lubricating oil main pipe, the feed pump both sides are respectively equipped with feed pump oil inlet pipe and feed pump oil outlet pipe, the lubrication
Oily main pipe is connect with feed pump oil inlet pipe, and the first oil mass and oil pressure monitoring apparatus are arranged on feed pump oil inlet pipe, described
First oil mass and oil pressure monitoring apparatus are connect by solenoid valve with lubricating oil bypath system.
Further, the feed pump oil outlet pipe is equipped with the second oil mass and oil pressure monitoring apparatus to scheme.
Further, first oil mass and oil pressure monitoring apparatus and the second oil mass and oil pressure monitoring apparatus pass through control to scheme
Device processed is connect with monitor and alarm successively.
The utility model has the beneficial effects that：By the first oil mass and oil pressure monitoring apparatus control lubricating oil by-pass switch with
And uninterrupted adjust, improve feed pump lubricating oil pipeline low oil pressure the problem of, pass through oil mass and oil pressure monitoring apparatus numerical value pair
The reason of than that can find oil pressure variation and variation in time, accomplishes to take precautions against in advance, prevent the generation of oil-free tile kilning, it is ensured that water supply
Pump normal operation.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific implementation mode

Specific embodiment of the present utility model is：As shown in Figure 1, electrically driven feed pump lubricating oil system, including fuel tank 1,
Feed pump 7, oil pump 2, auxiliary oil pump 3, lubricating oil main pipe, 7 both sides of the feed pump be respectively equipped with feed pump oil inlet pipe with to
Water pump oil outlet pipe, the lubricating oil main pipe are connect with feed pump oil inlet pipe, and the first oil is arranged on feed pump oil inlet pipe
Amount and oil pressure monitoring apparatus 6, first oil mass and oil pressure monitoring apparatus 6 are connected by solenoid valve 4 and lubricating oil bypath system 5
It connects.
Further, the feed pump oil outlet pipe is equipped with the second oil mass and oil pressure monitoring apparatus 8.
Further, first oil mass and oil pressure monitoring apparatus 6 and the second oil mass and oil pressure monitoring apparatus 8 pass through control
Device 9 processed is connect with monitor 10 and alarm 11 successively, oil mass and oil pressure can be monitored by monitor 10, when less than setting value
When, alarm 11 is alarmed, and reminds staff, the monitoring in real time of oil mass and oil pressure or the reason of finding low oil pressure provide according to
According to.
The preferred embodiment of the utility model is described above, it should be pointed out that the utility model not office
It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as with the common side in this field
Formula is practiced；Any technical person familiar with the field, in the case where not departing from technical solutions of the utility model ambit, foundation
