Abstract
The utility model relates to a high-volume combination pump, comprising a pump portion and an air separator portion; wherein an oil-gas separate cavity is provided with an oil feed-back valve; the outlet of the oil feed-back valve is communicated with an inlet passage of the pump; the upper cover of the air separator is equipped with an exhaust pipe, and the exhaust pipe is provided with an exhaust float valve; the exhaust float valve includes a valve rod, a spool, a valve base and a float, the float is fixed on the lower end of the valve rod, the valve base is connected with the exhaust pipe; and when the oil feed-back valve has the fault which makes the oil in the oil-gas separate cavity full, the float of the exhaust float valve goes upwards to push the valve rod to move up, which makes the spool and the valve base sealed and blocks the exhaust pipe, in order to prevent oil from overflowing to pollute the environment. The utility model is an environment-friendly type fuel charger combination pump.
Description
Technical field
The utility model relates to a kind of pump, particularly about a kind of unipump that is used for having on the oilling machine equipment Oil-gas Separation function.The utility model is applicable to the unipump that uses on the oilling machine equipment.
Background technique
In oilling machine equipment, pump is its heart component, and oily medium is realized the oiling purpose by pumping of pump.Oil contains a large amount of gas in course of conveying simultaneously, will be with Oil-gas Separation in refueling process.So deaerator also is the essential equipment of oilling machine.In the existing oilling machine, all pump and deaerator are combined into one, constitute the Oil-gas Separation unipump.As the patent No. is 962421243 unipump, and structure comprises the combination pump housing, combination pump cover, pump, filter assemblies, air separation assembly, outlet valve assembly, float-controlled valve assembly, spill valve.At delivery side of pump and air separation assembly ingress guide plate is housed, makes the fluid that enters the air separation assembly become eddy flow, eddy flow center air enters the Oil-gas Separation chamber by the exhaust port of outlet pipe, is discharged to atmosphere by the outlet pipe on the Oil-gas Separation chamber.Because the air of discharging from the air separation assembly contains part oil, so the float-controlled valve assembly is set in the Oil-gas Separation chamber, the outlet of float-controlled valve is communicated with the inlet of pump, when the oil in the Oil-gas Separation chamber reaches some, opens float-controlled valve oil is transmitted back in the inlet passage.Its subject matter is, breaks down can not reliably beat mouthful the time at float-controlled valve, and the oil in the Oil-gas Separation chamber can not be back to the import of pump, and the outlet pipe that can amass behind the full Oil-gas Separation chamber from its upper end is discharged to atmosphere, and environment is polluted.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, provides a kind of oil that can prevent to enter the big flow combination pump of the good environmental protection of atmosphere.
The technological scheme that realizes the utility model purpose comprises pump part and air separator part, Oil-gas Separation is provided with scavenger valve in the chamber, the outlet of scavenger valve and pump inlet channel connection, be covered with outlet pipe on the air separator, mainly be that outlet pipe is provided with the exhaust float-controlled valve, described exhaust float-controlled valve comprises valve rod, spool, valve seat and float, and float is fixed on the valve rod lower end, and valve seat is connected with outlet pipe.
The utility model beneficial effect compared with prior art is to be provided with the exhaust float-controlled valve on outlet pipe, and the oil in the Oil-gas Separation chamber amasss when expiring, the float of exhaust float-controlled valve come-up, promote to move on the valve rod, make spool and valve base sealing, outlet pipe is blocked, prevent that oil is excessive to environment generation pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure enlarged view at I place among the utility model Fig. 1.
Embodiment
Big flow combination pump as shown in Figure 1, comprise pump part and air separator part, pump 1 adopts vane pump, pump 1 outlet is communicated with air separator 2 imports, guide plate 3 is equipped with in outlet and air separator 2 ingress at pump 1, makes the fluid that enters air separator 2 become eddy flow, and eddy flow center air enters Oil-gas Separation chamber 5 by the exhaust port 4 of outlet pipe, wherein air is discharged to atmosphere through the outlet pipe 6 of 5 upper ends, Oil-gas Separation chamber, and oil is deposited in the Oil-gas Separation chamber 5.Be provided with scavenger valve 7 in the Oil-gas Separation chamber 5, the outlet of scavenger valve 7 is communicated with pump 1 inlet passage, and long-pending when a certain amount of when the oil in the Oil-gas Separation chamber 5, scavenger valve 7 is opened, and oil is back to the import of pump 1.On outlet pipe 6, be provided with the exhaust float-controlled valve, described exhaust float-controlled valve comprises valve rod 8, spool 9, valve seat 10 and float 11, float 11 is fixed on valve rod 8 lower ends, and valve rod 8 is connected on the valve seat 10 by nut 13, and valve seat 10 interconnects by link 12 with outlet pipe 6.When the oil in the Oil-gas Separation chamber 5 was long-pending full, float 11 come-ups promoted valve rod 8 and make spool 9 and valve seat 10 sealings, and outlet pipe 6 cuts out, and prevented that excessive environment is produced of oily medium from polluting, and this moment, air separator 2 lost the Oil-gas Separation effect.
