Abstract
A cooling circulation system of a water cooling engine comprises an engine, a water pump, a water tank and pipelines which are connected between the engine and the water tank, between the water pump and the water tank and between the water pump and the engine. A cooling circulation pathway except the water tank and the outlet pipe of the water tank is provided with a vent pipe. The connection point of the vent pipe and the cooling circulation pathway is not lower than the highest point of the inner cavity of the water pump. The water pump is connected with a drainage pipe communicated with the inner cavity of the water pump. The port of the vent pipe and the drainage pipe is sealed by a plug. The pipe serving as the vent pipe or the drainage pipe can be adjusted on length and running trend according to the arrangement situation of the whole vehicle, so the end sealed by the plug can be arranged on a place which is most convenient to install and dismantle, and t the exhaust operation when the cooling fluid is filled up and the routine drainage operation are convenient and labor saving; little dismantlement processing or no processing for vehicle coverage parts is needed.
Description
Technical field
The utility model relates to motor, relates in particular to refrigeration and circulation system of water-cooled engine.
Background technique
At present, the application of water cooled engine is more and more general on Motor Vehicle, the cooling system of water cooled engine is mainly by motor, water pump, formations such as the circulation pipeline of water tank and cooling liquid, because cooling recirculation system seals, when in water tank, adding inject cooling liquid, need carry out bleeding, specific operation process is: take out the short circle water pipe on the thermostat, when slowly adding inject cooling liquid short circle water pipe on thermostat continuous outflow cooling liquid being arranged, load onto the short circle water pipe, continue to add inject cooling liquid till the filler liquid level no longer descends, cover tank lid at last.If the short circle water pipe still has bubble on the thermostat, can unscrew behind the clamping bolt deaeration of the water pump cover lower left corner fastening.Pilot engine, make motor in the idling mode smooth running.At this moment, take off thermostat short circle water pipe, the short circle water pipe should flow out cooling liquid continuously on the thermostat.
As seen, the existing bleeding of water cooled engine when adding inject cooling liquid bothers very much, particularly for case type tricycle, the motor cover piece that is covered on vehicle frame hides fully, and short circle sebific duct and the clamping bolt on the water pump cover on the dismounting thermostat are all pretty troublesome.
The model utility content
Problem to be solved in the utility model provides a kind of exhaust and all refrigeration and circulation system of water-cooled engine very easily of operation that discharge water when adding inject cooling liquid.
For solving the problems of the technologies described above, the utility model provides a kind of refrigeration and circulation system of water-cooled engine, this system include motor, water pump, water tank and be connected motor and water tank between, between water pump and the water tank and the pipeline between water pump and the motor, on the cool cycles path except that water tank and radiator drain, be connected with outlet pipe, the tie point of outlet pipe and cool cycles path is not less than the peak of water pump inner chamber, be connected with the offlet that communicates with the water pump inner chamber on water pump, the port of outlet pipe and offlet all seals with plug.
Outlet pipe and offlet can increase and decrease length and move towards layout according to the deployment scenarios of car load, make it have an end of plug sealing to settle the place that is beneficial to dismounting onboard most, add inject cooling liquid or when discharging water at ordinary times, only need to do simple dismounting and even do not do dismounting and handle, take off plug on the pipe and just can easily realize exhaust and discharge water covering.
After adopting the technical solution of the utility model, make bleeding and the operation that discharges water at ordinary times when adding inject cooling liquid very convenient, quick, laborsaving, do not need or only need that vehicle cladding member is done very little dismounting and handle.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the utility model embodiment 2 a structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 1, Fig. 2, refrigeration and circulation system of water-cooled engine described in the utility model, have water tank 1, motor 4, water pump 5 and be connected motor 4 and water tank 1 between, between water pump 5 and the water tank 1 and the pipeline between water pump 5 and the motor 4.
As shown in Figure 1 and Figure 2, water pump 5 is installed on the crankcase body of motor 4, one end of tank inlet pipe 2 links to each other with thermostat on motor 4 cylinder heads, one end of radiator drain 9 connects the water intake of water pump 5, between the cylinder body of the water outlet of water pump 5 and motor 4, be connected with water pipe 14, between thermostat on motor 4 cylinder heads and water tank 1 waterexit end, also be connected with short circle water pipe 3.
Key of the present utility model is: be connected with outlet pipe 11 on the cool cycles path except that water tank 1 and radiator drain 9, the tie point of outlet pipe 11 and cool cycles path is not less than the peak of water pump 5 inner chambers; Be connected with the offlet 10 that communicates with water pump 5 inner chambers on water pump 5, the port of outlet pipe 11 and offlet 10 all seals with plug.Outlet pipe 11 can be connected the arbitrary position that is not less than water pump inner chamber peak except that water tank 1 and radiator drain 9 on the cooling peripheral passage, therefore numerous embodiments can be arranged, and only is illustrated for two example two below.
Embodiment 1, as shown in Figure 1, on the water pump cover of water pump 5, be respectively equipped with exhaust fitting 7 and offlet joint 6, be connected with outlet pipe 11 in the exhaust fitting 7, be connected with offlet 10 on the offlet joint 6, outlet pipe 11 and offlet 10 all communicate with the inner chamber of water pump 5, and outlet pipe 11 seals with outlet pipe plug 12, offlet plug 13 respectively with the port of offlet 10.Exhaust fitting 7 is positioned at the top of water pump cover, should guarantee that promptly exhaust fitting 7 the inners are higher than the normal level of liquid in the water pump.Offlet joint 6 is positioned at the bottom of water pump cover, makes offlet joint 6 inner port be in the extreme lower position of water pump inner chamber as far as possible, when it guarantees to discharge water remaining cooling liquid is drained.At the bleeder screw of height on the water pump cover up and down between exhaust fitting 7 and offlet joint 6.
