Abstract
The utility model discloses a gear pump of transmitting firefighting foam. The gear pump comprises a pump body, wherein the pump body is provided with a set of driving shafts and a set of driven shafts. The driving shaft and the driven shaft are respectively provided with a gear and two gears are meshed with each other. The pump body is provided with a liquid inlet and a liquid outlet. The pump body is in a mechanical seal structure, and the pump body is provided with a bush. The pump body, the bush and the gear are made of bronze materials, and the driving shaft and the driven shaft are made of stainless steel. The gear pump aims at providing special foam-transmitting machinery which meets the international standard of GBGB6245-2006 and GB20031-2005 for the foam pump. The gear pump has the advantages of being high in working efficiency, suitable for various foam liquid without the influence of viscosity of the foam, and strong in suction capacity, allowing a short-time idle running in the pump when the foam liquid is filled, being used without interruption when the foam is filled and prolonging the time of foam fire-fighting. Meanwhile, the pump body is protected and can be in a stable and continuous working state under a high-pressure condition. The gear pump of transmitting firefighting foam can prolong service life.
Description
Technical field
The utility model relates to a kind of fire-fighting foams conveyance gear pump.
Background technique
Existing fire-fighting foams pumping unit defectiveness on sealing, the problems such as the pump housing has seepage under large pressure, sweat, unreasonable on design of gears, inefficiency, the prior art corrosion resistance is poor, when static pressure progressively reaches 4Mpa pressure, the pump case of prior art there will be distortion and seminess.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of increasing work efficiency, and the protection pump housing itself can be stablized continuous firing, the fire-fighting foams conveyance gear pump increased the service life under the High Voltage state.
Complete skill scheme of the present utility model is, a kind of fire-fighting foams conveyance gear pump, comprise a pump housing, is provided with one group of driving shaft and driven shaft in the described pump housing, be respectively arranged with a gear on described driving shaft, driven shaft, described two gears are intermeshing; A side of opening in described gear engagement on the described pump housing is provided with a liquid entering hole, is provided with a liquid outlet on the pump housing opposite side relative with liquid entering hole; The described pump housing adopts mechanical seal.
Also be provided with lining on the described pump housing, the described pump housing, lining and gear are made by bronze material.
Described driving shaft and driven shaft are stainless steel shaft.
Fire-fighting foams conveyance gear pump structurally face has the various configurations mode, and may there be great difference in two similar gear pumps of outward appearance in material, seal form and rotation in form.
Therefore the utility model has been compared following beneficial effect with present technology:
The utility model fire-fighting foams conveyance gear pump is the high-speed overload positive displacement gear pump of standard, the pump housing of gear pump, lining and pump gear are all to adopt bronze manufacture, main, driven shaft adopts the stainless steel material manufacture, corrosion resistance is strong, sealing adopts mechanical seal, good airproof performance, under the pressure of 2.2Mpa, the pump housing and parts ne-leakage, the defect such as sweat, when static pressure progressively reaches 4Mpa pressure, pump case is without distortion and seminess, this gear pump has good self-absorption function, utilize rational design of gears, increase work efficiency, the protection pump housing itself, can stablize continuous firing under the High Voltage state, no load running is greater than 10 minutes, increase the service life.

| Bearing | 4000 hours | 25 grams |
| Driving gear | 4000 hours | 100 grams |
(2) integral demounting
1.. the place that guarantees as much as possible work is clean, in order to avoid the part of gear pump inside suffers damage.
2.. change packing ring and oil sealing envelope when repairing, change when mounted all keys, elastic washer, sealing gasket etc.
3.. when dismounting sealing and oil sealing, with metal tools, do not prized, scraped.Because may scratch sealing surfaces like this, remove to tear open these things with wood or plastic tool.
4. when any one parts of dismounting,, conscientiously with reference to exploded view (Fig. 4-1), to note the contact between inner body especially, to the familiar correctness that is conducive to improve dismounting speed and assembling of structure.
5. for to prevent that moisture or foreign matter from entering from unlimited position, in dismounting, just with protecting jacket or lid, these places are built afterwards.Lapping can be with clean paper or cotton.
6.. as far as possible only dismounting needs parts needed for repair and replacement, not the inoperative parts of the more multipair repairing of dismounting.
Therefore, the utility model fire-fighting foams conveyance gear pump is the high-speed overload positive displacement gear pump of standard, the pump housing of gear pump, lining and pump gear are all to adopt bronze manufacture, main, driven shaft adopts the stainless steel material manufacture, corrosion resistance is strong, sealing adopts mechanical seal, good airproof performance, under the pressure of 2.2Mpa, the pump housing and parts ne-leakage, the defect such as sweat, when static pressure progressively reaches 4Mpa pressure, pump case is without distortion and seminess, this gear pump has good self-absorption function, utilize rational design of gears, increase work efficiency, the protection pump housing itself, can stablize continuous firing under the High Voltage state, no load running is greater than 10 minutes, increase the service life.
