Description
Technical field
The utility model relates to a kind of engineering machinery fuel oil pre-filtrating equipment.
Background technique
Be diesel emission and the noise regulations requirement of satisfying increasingly stringent, electronic injection diesel engine is adopted in engineering machinery in a large number.Electronic injection diesel engine adopts high-pressure injection system, and jet pressure is generally: 120～160Mpa or higher, and each plunger coupled parts in high-pressure injection system and exterior part precision all very high, the injection hole on injection nozzle diameter is little, and is more responsive to the sediments in diesel oil.Impurity in diesel oil is the high speed impact oil nozzle under the effect of high pressure, be easy to cause wearing and tearing and the obstruction of oil nozzle, make it and to work, cause that the diesel engine fuel consumption amount increases, diesel engine power descends, the series of problems such as noise is larger, unstable idle, discharging increase.Need to take the necessary measures and reduce impurity in diesel oil, keep the ejecting system cleaning, make ejecting system be in for a long time good working state.And engineering mechanical device is to carry out in the working site mostly when refueling in the job location, because work under bad environment exists secondary pollution (comprising the pollution of oil tank, oil drum, oil gun, oil pipe, the environmental pollution of job site).Therefore install grade one filter additional on the own oil-fired system of machinery, but do not reach good effect, grade one filter can only filter a part of impurity, and moisture filter very little, and some moisture also can enter oil-fired system to be caused and can't work.Humidity according to environment in fuel tank is different, and the water accumulating volume of generation is also different, only can't reach the effect of filtering moisture content by the own filtration system of machinery.There is different humidity according to residing environment.After work is parked, can produce in various degree ponding and impurity in fuel tank, and the original fuel oil filter of machinery can not satisfy demand and the standard of filtering fully.
The diesel oil of China pollutes very seriously for various reasons now, and the characteristics of diesel oil itself are deposited a period of time and will be produced the pollutants such as a lot of colloids, asphalitine in addition.Although the impurity particle in NBS requirement diesel oil should be less than 10 microns, but the actual conditions due to the market diesel oil that supplies itself and construction environment, make the diesel oil pre-filtering that meets NBS change every one, two day and once can't normally use, be fit to even external imported engine also will be produced specially the diesel fuel filter that Chinese market is used now.Can normally move in order to make diesel engine, also due to filter cleaner manufacturer in order to reduce production costs, all between 40～120 microns, Here it is causes the billowing reason of all diesel engine afterbody black smokes to all filter cleaner precision in market, C China at present.That is to say, because the pollution of diesel oil itself has very seriously just caused a phenomenon---senior diesel oil pre-filtering can't normally be used, poor ignition quality fuel filter cleaner damage motor, thus the universal phenomenon that Service Life of Disel Engines is short, failure frequency is high, maintenance expenses is large, diesel consumption is large, the tail gas black smoke is large caused.The electronic fuel injection engine of machinery is very high to the quality requirements of machinery fuel oil, the oil nozzle of electronic fuel injection engine is high-tech core product, in case have moisture content and impurity to enter oil-fired system, will cause the damage in various degree of oil nozzle and oil transfer pump, keep the pure, extremely urgent of fuel oil.
Summary of the invention
For addressing the above problem, the utility model provides a kind of engineering machinery fuel oil pre-filtrating equipment, to solve the problem of discharging foreign material and moisture content, the replacement cycle of prolongation system filtering core device, reduce fuel consume, extend the working life of oil sprayer, keep the ejecting system cleaning, make ejecting system be in for a long time good working state.
For achieving the above object, the utility model adopts following technological means:
A kind of engineering machinery fuel oil pre-filtrating equipment, it is characterized in that this device mainly comprises: main fuel reservoir, oil transfer pump, oil and water seperator, primary fuel case and motor, the oil outlet that is positioned at main fuel reservoir bottom is connected to oil transfer pump by oil pipe, be connected to oil and water seperator through oil transfer pump again, oil and water seperator is connected to drop tank by oil pipe, the fuel oil in drop tank by oil pipe be delivered to motor, unnecessary fuel oil is sent main fuel reservoir back to by the overflow oil pipe.
Described oil transfer pump and oil pipe connection mouth place's assembling compression resistance are: " O " RunddichtringO of 0.1～0.3MPa prevents that oil leakage phenomenon from occuring.
Described the oil and water seperator afterbody install one after filtering impurity and the plastic tube of moisture discharging, impurity and moisture after filtration are discharged in a storage box, solved the problem of discharged waste.
Oil transfer pump is fixedly mounted on one keeps relatively far away and vibrationless position with motor, oil transfer pump is overheated to solve, the problem of shake.
Described connected pipes is fixed by a snap ring with bayonet, and an other end of snap ring is fixed on body; With snap ring, connected pipes is fixed on body, to solve the problem of oil pipe shake.
Beneficial effect:
(1), the engineering machinery electronic injection diesel engine is had relatively high expectations to diesel quality, use all restrictions if having time of diesel-oil filter element device, the diesel-oil filter element device replacement cycle as excavator is: 250 hours, because China Diesel is second-rate, may needing of having changed in advance, otherwise will cause the diesel-oil filter element device to lose efficacy, and be expected to system's filtering core device replacement cycle of machinery is extended 2～3 times after using this system.
(2), the ejecting system pressure of electronic injection diesel engine is higher, when the turbidity test of diesel oil are not high, impurity wherein is the high speed impact oil nozzle under high pressure, moisture can't burn, cause wearing and tearing or the corrosion of oil nozzle, piston, cause that the diesel engine fuel consumption amount increases, diesel engine power descends, the series of problems such as noise is larger, unstable idle, discharging increase.Be expected to the machinery fuel consumption is reduced by 5% left and right after using this system.
This device infiltrates moisture for the diesel engine that engineering machinery is used because of fluid in main fuel tank under cold machine state; and the problems that under abominable working condition, in fluid, impurity exists more; effective moisture and the impurity in filter fuel; thereby the oil nozzle of having protected motor is not subjected to the erosion of moisture and impurity; extend the working life of oil nozzle; proper extension engine maintaining maintenance period has reduced device maintenance, cost of upkeep.
