Abstract
The utility model relates to a diesel engine fuel pump and water pump supporting tank which is a cast iron inblock cast part. Mounting holes used for mounting water pumps, a fuel pump, inspection hole covers and an output shaft sealing structure are distributed in a tank body, a fuel overflow valve mounting hole is further formed, a cooling water cavity is cast at the top of the tank body, and the output shaft sealing structure is composed of a sealing ring and an oil seal. A fuel fine filter is refitted on the side face of an engine body, an upper structure in the prior art is omitted to free up a space, and the cooling water cavity is directly cast on the tank body, so that external cooling water pipelines are decreased; mounting position of a fuel overflow valve is increased, and pipelines of a fuel system are decreased; by the adoption of the novel output shaft sealing structure, sealing effect is improved.
Description
Technical field
The utility model relates to a kind of diesel engine oil pump and water pump supported box, belongs to diesel engine manufacturing technology field.
Background technique
In the prior art, high-power diesel engine (for example 240/275 series) is arranged on the free-ended oil pump of body and water pump supported box is cast iron cast inblock part, bottom divides casing distribution 6 machining holes, and the sealing cover of water pump, oil pump, inspection cover, output shaft is installed respectively.Casing top is cast iron end plate, and centre arranges secondary fuel oil filter bearing, and left and right is the adjustable support of duplicate gear, sees Fig. 1.Mainly there is following problem in this scheme:
1, secondary fuel oil filter bearing has been occupied very large space.
2, the seal cap sealing effect of output shaft is undesirable.
3, need external part cooling water pipeline, make cooling water pipeline complexity.
4, lack the mounting point of oil overflow valve, the pipeline of lubricating oil system is increased.
Model utility content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of diesel engine oil pump and water pump supported box are provided.
The purpose of this utility model is achieved in that a kind of diesel engine oil pump and water pump supported box, for cast iron cast inblock part, for the mounting hole that water pump, oil pump, inspection cover, output shaft seal structure are installed, be distributed in casing, it is characterized in that being also provided with oil overflow valve mounting hole on casing, casing top is cast with cooling water chamber.
In order to realize better the object of wanting model utility, described output shaft seal structure consists of seal ring and oil sealing.
Scheme of the present utility model, is retrofitted to body side by secondary fuel oil filter, has cancelled the superstructure of prior art, and vacating space is directly cast cooling water chamber on casing, has reduced outside cooling water pipeline; Increase the mounting point of oil overflow valve, reduced the pipeline of lubricating oil system; Adopt new output shaft seal structure, improved sealing effect.
Accompanying drawing explanation
Fig. 1 is diesel engine oil pump and the water pump supported box schematic diagram of prior art.
Fig. 2 is the utility model embodiment's diesel engine oil pump and water pump supported box schematic diagram.
Fig. 3 is the structural representation of output shaft seal structure 4 in Fig. 2.
In figure, be labeled as: 1-oil pump mounting hole, 2-peep hole, 3-water pump mounting hole, 4-output shaft seal structure, 5-secondary fuel oil filter support, 6-adjustable support, 7-cooling water chamber, 8-oil overflow valve mounting hole, 9-seal ring, 10-oil sealing.
Embodiment
Referring to Fig. 2 and Fig. 3, the diesel engine oil pump of the present embodiment and water pump supported box, adopt cast iron cast inblock.On casing, except having distributed six, for installing water pump, oil pump, handhole cover and output shaft seal structure mounting hole 1,2,3,4, be also provided with the mounting hole 8 of an oil overflow valve, thereby reduced the pipeline of lubricating oil system.Secondary fuel oil filter is retrofitted to body side, thereby has cancelled the superstructure of prior art, vacating space, directly casts cooling water chamber 7 on casing, has reduced outside cooling water pipeline.Output shaft seal structure 4 consists of seal ring 9 and oil sealing 10, has improved sealing effect.
Claims (2)
1. a diesel engine oil pump and water pump supported box, for cast iron cast inblock part, for the mounting hole that water pump, oil pump, inspection cover, output shaft seal structure are installed, be distributed in casing, it is characterized in that being also provided with oil overflow valve mounting hole on casing, casing top is cast with cooling water chamber.
2. diesel engine oil pump according to claim 1 and water pump supported box, is characterized in that described output shaft seal structure consists of seal ring and oil sealing.
