Abstract
The utility model relates to a fuel filter manual pump with the oil absorption and purification function, which aims to solve the problem that a one-way valve is disabled due to the quality of oil, thereby finally resulting in low oil pumping efficiency and failure of the fuel filter manual pump. The fuel filter manual pump comprises a filter manual pump and a filter; the filter manual pump comprises a pump body, an oil inlet pipe and an oil outlet pipe; one-way valves are respectively arranged at the oil inlet pipe and the oil outlet pipe; and the fuel filter manual pump has an improvement that the filter is connected to the oil inlet pipe in series. The fuel filter manual pump adopts another scheme that a three-way pipeline is arranged on the oil inlet pipe; the second port of the three-way pipeline is communicated with the filter, and the third port thereof is communicated with the inlet of a main one-way valve; and the outlet of the main one-way valve is communicated with the oil outlet pipe. When the fuel filter manual pump is in operation, the filtered clean fuel oil enters the inner cavity of the manual pump and can not result in abnormal failure of the one-way valve due to impurities, thereby reducing the failure probability of the manual pump, improving the reliability of the manual pump, and prolonging the service life and the replacement period of the manual pump, and saving the replacement cost for a user.
Description
Technical field
The utility model relates to a kind of fuel filter hand pump.
Background technique
The effect of the manual oil feed pump of fuel filter is that the air in new filter cleaner of oil-fired system and the pipeline is discharged, and the fuel oil in the fuel tank filled with filter cleaner or fuel pipe by the low pressure oil circuit, no air existence in the oil circuit of oil-fired system guarantees to start normal startup of function and work when guaranteeing engine operation.
At present, on the market the manual pump of the filter cleaner that supplies be mostly fuel oil earlier through oil pipe, hand pump filler opening, in line check valve to the hand pump pump chamber, again by fuel-displaced one-way valve, hand pump oil outlet to filter cleaner.When the hand pump gland lifts by pressure spring, fuel-displaced closed check valve, in line check valve is opened, and the fuel oil in the fuel tank enters manual pump chamber by oil input channel, in line check valve; When the hand pump gland was depressed by external force, in line check valve was closed, fuel-displaced one-way valve opens, and manually the fuel oil in the pump chamber is pressed in the filter cleaner by fuel-displaced one-way valve.Repeat like this to press by the hand pump gland, the air in the new filter cleaner will be squeezed filter cleaner by fuel oil, and fuel oil arrives oil road after filter cleaner filters simultaneously.Manually when air pump inoperative and diesel engine machine proper functioning fuel oil by oil input channel, main one-way valve, filter cleaner to flowline.
From above process as can be known, the fuel oil that enters manual pump chamber during hand pump work is to filter without filter cleaner, has the more fuel oil of impurity, and manual pump work is produced following harmful effect:
One, when the larger particles in the fuel oil that filters without filter cleaner or impurity are deposited in fuel-displaced one-way valve place, will cause fuel-displaced one-way valve to be in opening-wide state.Because fuel-displaced one-way valve communicates with oil road, and must squeeze air in the filter cleaner that makes new advances with fuel oil behind the filter cleaner that more renews,, just illustrate that also the hand pump inner chamber communicates with ambient atmosphere so oil road at this moment communicates with atmosphere.Because interior external atmosphere pressure equates that this moment, hand pump can't be extracted into fuel oil in the hand pump inner chamber, thereby can't discharge the air in the new filter cleaner.
Two, when the larger particles in the fuel oil that filters without filter cleaner or impurity are deposited in the in line check valve place, will cause in line check valve to be in opening-wide state.Because in line check valve communicates with oil input channel, and must squeeze air in the filter cleaner that makes new advances with fuel oil behind the filter cleaner that more renews, so the fuel oil in the fuel tank must be extracted in the manual pump chamber, fuel oil could be pressed onto in the new filter cleaner after by pressure in line check valve being opened, thereby squeeze air in the filter cleaner with fuel oil.But because in line check valve also is in open mode, can cause fuel oil in the manual pump chamber like this in being pressed into new filter cleaner in, a part has pushed back again in the fuel tank, has so just increased the number of times of pushing hand pump, has reduced the oily efficient of pump of hand pump.
Because the working life of filter cleaner, about 1.2～1.5KM (about 3 months), the filter paper in the filter cleaner was substantially blocked up by the impurity in the fuel oil at this moment substantially, this moment, pressure difference was bigger, must more renew filter cleaner.And after each the replacing, all might be when discharging air in the new filter cleaner because the larger particles impurity that has in the fuel oil is piled up at the one-way valve place with hand pump, make one-way valve be in opening-wide state, cause the hand pump operational difficulties maybe can't work, thereby can't discharge the air in the new filter cleaner.
By the existing hand pump Quality Feedback in market is added up, because of oil quality causes the probability of one-way valve inefficacy greatly about about 3%, and for the worse light card of fuel qualities, minibus market, the hand pump one-way valve lost efficacy and the inefficacy that causes especially up to about 10%.
Summary of the invention
To lose efficacy in order solving because of oil quality causes one-way valve, and finally to cause the low and Problem of Failure of fuel filter hand pump pump oil efficient, the utility model provides a kind of fuel filter hand pump with exhaustion functional oil.
Technical solution of the present utility model is as follows:
Have the fuel filter hand pump of exhaustion functional oil, comprise manual pump of filter cleaner and filter cleaner, the manual pump of described filter cleaner comprises the pump housing, oil inlet pipe and oil outlet tube, and oil inlet pipe and oil outlet tube place are provided with one-way valve respectively;
Described filter cleaner is connected on the inflow pipeline.
Described oil inlet pipe is provided with three-way pipe, and second port of three-way pipe is being communicated with filter cleaner, and the 3rd port of three-way pipe is being communicated with the import of main one-way valve, and the outlet of main one-way valve is being communicated with oil outlet tube.
The utility model and existing fuel filter hand pump relatively have the advantage of several respects:
When 1, the utility model hand pump was worked, the clean fuel oil after the filtration entered the hand pump inner chamber, can not cause one-way valve because of the improper inefficacy that impurity causes, and had reduced the probability that hand pump lost efficacy, and had improved the reliability of hand pump.
2, the utility model hand pump has reduced the sensitivity to fuel qualities, adapts to the vehicle fuel market environment of China more.
3, the utility model hand pump can prolong the working life and the replacement cycle of hand pump, for the user saves replacement cost.
