Description
Technical field
The present invention relates to a kind of oil flushing equipment.Particularly relate to and a kind ofly being installed under the fuel tank by Oil pump electrical machinery, save the oil flushing time, improve the compact efficient modularization oil flushing equipment of oil flushing efficient.
Background technology
There is following present situation in domestic general oil flushing equipment at present:
1, the design of present domestic oil flushing equipment all adopts Oil pump electrical machinery base and oil tank base support in same absolute altitude level.Oil pump suction inlet height is higher than the fuel tank bottom, for guaranteeing not exhaust of oil pump, generally requires the fuel tank minimum level to exceed pumping hole 75mm or 1.5 times of calibers simultaneously, gets big value among both.Such design is feasible for the work station of workshop, but for oil flushing equipment, has following defective:
(1) owing to usually add the flushing liquor (crude oil) of fuel tank, generally about NAS9 level/10 grade, and the flushing required precision: servo-drive system is in NAS5 level to 7 grade, the NAS6 of proportioning valve system level to 8 grade, and conventional system is at 7 grades to 9 grades.Fluid below the fuel tank minimum liquid level in other words need be flushed to the NAS5 level to the NAS8 level from NAS9 level or NAS10 level in this case, like this fluid flushing under the fuel tank minimum liquid level has been increased washing time.
(2) because the pumping hole liquid level is higher than the fuel tank bottom, so after fluid was got back to fuel tank, the impurity that is blended in the fluid can partly be deposited on the fuel tank bottom.When oil flushing system pressure or flowed fluctuation, also have impurity and enter circulation again.When this just caused oil flushing having occurred, first day sometimes passed examination checked underproof situation in second day.
2, simultaneously owing to reasons such as the caliber of hydraulic system, duct lengths, need different flushing flow rate, need 1000L/min to 3000L/min, must produce the different flow oil flushing equipment for this reason; Because scouring stage need often be transported to different building sites, because the appearance and size of scouring stage is bigger, cause on-the-spot scouring stage and the transportation difficulty of arranging simultaneously.
3, before flushing, should adopt clean compressed air operation to purge according to oil flushing technology.Purging all is to adopt at the scene by root to be undertaken at present, and needing relatively wastes time and energy by root dismounting pipe joint.
4, the connection of oil flushing adopts temporary pipeline to connect, and the specification requirement that temporary pipeline is installed is identical with formal pipeline, need pickling after, argon arc welding is welded, and waste material and man-hour.
5, present scouring stage all adopts single-stage to filter or double-filtration, and filtration time is long.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of current global mechanism that can realize flushing oil, saving oil flushing time, raising oil flushing efficient, the compact efficient modularization oil flushing equipment of being convenient to on-the-spot layout and transporting.
The technical solution adopted in the present invention is: a kind of compact efficient modularization oil flushing equipment, comprise: fuel tank, the oil-out of described fuel tank is successively by first ball valve by pipeline connection, rubber is taken over, the first side ball valve, by motor-driven helical-gear pump, second ball valve, first filter, second filter, the second side ball valve and the 3rd ball valve are to the oil-out of this oil flushing equipment, the oil return opening of described fuel tank is successively by the low pressure return filter by pipeline connection, the 3rd side ball valve and the 4th ball valve are to the oil return opening of this oil flushing equipment, the oil-feed oral-lateral of described the 3rd ball valve and the fuel-displaced oral-lateral of low pressure return filter also pass through pipeline connection, and this connecting pipeline is provided with the 5th ball valve, also be provided with two overhead type return filters that are communicated with oil-in in the described fuel tank, described motor and helical-gear pump all be arranged on the fuel tank outside below.
The bottom surface of described fuel tank is higher than the inlet port height of oil pump.
The bottom surface of described fuel tank is provided with for the fuel tank parallel interface that is connected in parallel with other oil flushing equipment.
The described first side ball valve refuels as fuel tank and uses valve, connects oil-resisting rubber hose at the first side ball valve place and is communicated with in the oil drum.
The described second side ball valve is as purging valve.
Compact efficient modularization oil flushing equipment of the present invention has the following advantages:
1, because diminishing of fuel tank can provide the space of more crossing to arrange filter, so scouring stage filters the progression height, flushing speed is fast.
2, satisfying under the oil pump normal operation situation consumption minimum of flushing oil, the current global mechanism of realization flushing oil.
3, can modular combination, realize the modularization production of rinse-system, can freely form the rinse-system that single pump is any flow of radix by each scouring stage, be convenient to take full advantage of resource, be convenient to the setting of scouring stage working position.
4, reduce the scouring stage volume, in light weight, be convenient to on-the-spot the layout and transportation
5 reduce measure materials in the oil flushing process, save the oil flushing time, improve oil flushing efficient.
