Description

Fluid change system

The present invention relates to fluid conversion field, relate in particular to self-changing's fluid change system of using by oneself for the amateur, this system is used for removing from vehicle and machine then and there including, but not limited to waste fluid materials such as various types of motor-oils, hydraulic oil, transmission oil, lubricating grease, various freezing mixtures with the improved procedure handle, and to vehicle and the new fluid of machine supply.Wherein, collect this kind waste materials and supply new material, all need not cleaning this system after using this system, and waste fluid can not lose, and conversion is all finished in safe but also efficient mode not only each.

The motor of vehicle and machine and the lubrication system in the motor, requiring its oiling agent is lubricant oil, and oil purifier, periodic replacement.

Under the situation of automobile, be lubricated oily conversion, by tradition and be still at present a big basin or funnel are placed automobile oil groove below, taking away oil drain plug makes oil depend on gravity to discharge, old oil purifier is taken off from cylinder block, load onto new oil purifier, again oil drain plug is loaded onto, and inject new oil to motor.The waste oil that is collected must be with reprocessing.

Be listed in a kind of harmful waste that must handle now owing to highly recognize the harm of motor-oil to environment, this oil plant, the processing of motor waste oil has been become routine, few people do not note this part thing.Another problem that is not suggested as yet is residual this problem of old oil purifier that waste oil is arranged.These old oil purifiers are often arbitrarily thrown away in the open air by the people.

Part is owing to these problems, and in recent years, special-purpose quick oil plant conversion facility is popularized.These facilities of lubricant oil supply are fast promised and fast and easily service generally are provided, and occupy waste oil and old oil purifier.These facilities are collected the motor waste oil with bucket or groove usually, and waste oil is then transported or taken away by oil delivery truck.These commercial facilitys carry out the expense that the oil plant conversion is received, and surpass used new oil plant and new oil purifier cost 3 to 6 times usually, even more.

Would rather oneself render a service for vehicle or supply not rise special-purpose equipment to carry out the people of oil plant conversion receipts than high cost for many, how not only safety but also treat and dispose waste oil legally and useless oil purifier still is an individual problem greatly.Under the situation of old oil purifier,, and often can not accepted by the people along with the motor waste oil with the old oil purifier of crossing even this oil purifier has drained also still residual considerable waste oil.Hobby person's formula end user that uses by oneself becomes jar to become bottle ground to buy a new oil plant often, old oil plant is emitted in the oil extraction dish, and collected waste oil is reinjected in the new Carburetor, or adorn with other containers and to collect waste oil.The end user also is faced with such problem: how to handle collect Residual oil in waste oil, old oil purifier and the oil-collecting disk.In addition, accept waste oil and the oil purifier that gives up because other people are unwilling, many people just can not suitably dispose waste oil, be stained with oily container and oil purifier, so all can endanger environment.In fact, the new oil plant of institute's sale of electricity motivation, quantity is above being collected about 69% of waste oil.Although some oil has been burnt in vehicle, the final home to return to of many this waste oils is unlawfully abandoned in the strong wind and is blown off to open-air, throws the lake with on the ground waste, or exists in the container for a long time dullly.

For many machines, vehicle and aircraft, cooling fluid, hydraulic fluid and lubricant oil or the like must regular replenishment and/or replacings.In many cases, their fluid conversion is not only difficult but also dirty and messy.Under the personal aircraft situation, the oil plant conversion process is often not only consuming time but also dirty and messy.Under the situation of mining machinery and equipment, mining environment often stirs up a cloud of dust, thereby must frequent change oil plant and lubricating grease, and when new oil plant of machine supply and lubricating grease, is difficult to not sneak into dust.
