Abstract
The utility model relates to a wet cylinder liner machine body of a water cooling diesel engine. A plurality of cylinder liner holes are arranged in the wall of the machine body along the longitudinal direction by sections; a depressed and opened upper water distributing water channel, one end of which is provided with a through hole communicated with the outside, is arranged on the side surface of the machine body; a closed lower water distributing channel is also arranged under the upper water distributing channel; a first communicating hole communicated with the lower water distributing channel is arranged on the lower edge of the other end of the upper water distributing channel; a plurality of second communicating holes which are communicated with the cylinder liner holes correspondingly are arranged on the inner wall of the lower water distributing channel. As a result, under the equal power of diesel engines, the heat radiating areas of engine oil coolers arranged on the upper water distributing channel can be decreased.
Description
The utility model relates to a kind of water-cooled diesel engine wet cylinder liner body.
Existing water-cooled diesel engine wet cylinder liner housing construction such as Fig. 1, shown in Figure 2, be formed with a water cooling system by the cavity of arranging some UNICOMs in this body 1, that is: segmentation longitudinally is provided with several sleeve ports 11 in the wall of body 1, the upper water distributing channel 13 of one depression is set at the side surface of body 1, end at this upper water distributing channel is provided with a perforation 19 that links with the external world, in this upper water distributing channel, be provided with simultaneously several linked holes 12 again, by in each body sleeve port 11, placing some wet cylinder liner 17, make and form several between the outer wall of each body sleeve port 11 inwall and each cylinder sleeve 17 along jacket-cooling water chambeies 15 that the body longitudinal divisions is arranged, each set linked hole 12 makes cloth water channel 13 and each jacket-cooling water chamber 15 UNICOM, just can form a water cooling system as long as cover cover plate 16 on cloth water channel 13 like this.General placement machine oil cooler 18 in upper water distributing channel, a part of by the cooling water that upper water distributing channel one end perforation 19 enters through machine oil cooler 18, and another part cooling water directly enters each jacket-cooling water chamber 15, such structure, make the part cooling water enter jacket-cooling water chamber 15 in advance, machine oil cooler does not obtain sufficient heat exchange just as ducking in drink, so when the full speed full load, the machine oil of the diesel engine of this cooling structure is imported and exported the temperature difference and is generally had only 2～3K.Make the machine oil thermal cycle of diesel engine obtain balance, generally need the machine oil cooler of bigger heat diffusion area, the volume of machine oil cooler is also just corresponding bigger.
The purpose of this utility model is to provide a kind of water-cooled diesel engine wet cylinder liner body, by UNICOM's cavity of arranging in this body, make and have better cooling effect with the water cooling system that peripheral accessory cover plate and cylinder sleeve form by this UNICOM's cavity, under same diesel engine power, the lube oil cooler for diesel engine component size is reduced, make the compact structure of diesel engine.
The purpose of this utility model realizes by following technical proposals, that is: a kind of water-cooled diesel engine wet cylinder liner body, segmentation longitudinally is provided with several sleeve ports in the wall of this body, the upper water distributing channel of the opening of a depression is set on the side surface of this body, and an end of this upper water distributing channel be provided with one with the extraneous perforation that links, be characterized in: below described upper water distributing channel, also be provided with a lower water distributing channel of remaining silent, and on the lower limb of the upper water distributing channel the other end, be provided with first linked hole that communicates with this lower water distributing channel, on this lower water distributing channel inwall, be provided with several and sleeve port second linked hole of corresponding UNICOM one by one again.
Owing to adopted above-mentioned technical solution, lower water distributing channel promptly is set, make the cooling water that enters by the perforation of upper water distributing channel one end earlier through upper water distributing channel, enter each jacket-cooling water chamber through lower water distributing channel then, formed thus water cooling system has better cooling effect, when diesel engine full speed full load, can make the import and export temperature difference of machine oil reach 10K or surpass 10K.Can make the compact structure of diesel engine like this, under same diesel engine power, the size of machine oil cooler can reduce.In addition, cooling water is heated through after the machine oil cooler, enters body jacket-cooling water chamber again, and higher water temperature can make diesel engine comparatively fast enter effective working condition.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Fig. 1 is the side view of existing water-cooled diesel engine wet cylinder liner body;
Fig. 2 is an A-A sectional drawing among Fig. 1;
Fig. 3 is the side view of the utility model water-cooled diesel engine wet cylinder liner body;
Fig. 4 is a B-B sectional drawing among Fig. 3.
As shown in Figure 3 and Figure 4, the structure of the utility model water-cooled diesel engine wet cylinder liner body is: the upper water distributing channel 13 that the opening of a depression is set on the side surface of this body 1, the shape of this upper water distributing channel can be rectangular, end at this upper water distributing channel is provided with a perforation 19 that links with the external world, segmentation longitudinally is provided with several sleeve ports 11 in the wall of this body 1, below described upper water distributing channel, also be provided with a lower water distributing channel of remaining silent 14, its shape can be similar to upper water distributing channel, and on the lower limb of the upper water distributing channel the other end, be provided with first linked hole 131 that communicates with lower water distributing channel, on these lower water distributing channel 14 inwalls, be provided with several and described sleeve port 11 second linked hole 12 of corresponding UNICOM one by one again.
The utility model body 1 is general by wet cylinder liner 17 is installed in sleeve port 11, makes the outer wall of wet cylinder liner 17 and the inwall of body sleeve port 11 form a jacket-cooling water chamber 15, and the quantity in jacket-cooling water chamber 15 is decided by the cylinder number of diesel engine.Need only the upper water distributing channel 13 loam cake upper cover plates 16 at opening like this, the cavity of UNICOM has formed the interior water cooling system of diesel engine of a sealing thus.
