The expansion tank provided by the utility model is a novel cooling system expansion tank specially used for engine testing, and by using the expansion tank, bubbles generated due to high temperature in an engine cooling circulating system can be effectively reduced, and a stable box internal pressure is established in a water tank body.
Description
Technical field
The utility model relates to engine art, particularly a kind of special-purpose cooling system swelling water tank of Engine Block Test that carries out.
Background technique
Swelling water tank is as the indispensable part of Engine Block Test cooling system; Play an important role to storing engine coolant and keeping whole engine-cooling system cooling liquid liquid level; Because the bubble that localized hyperthermia produces is able to eliminate through reflux condensation mode, swelling water tank produces contribution to the pressure of keeping whole cooling system to motor simultaneously in the high-load operation process.
Current in the Engine Block Test process because the design of swelling water tank is unreasonable and improper to the water treatment of water tank string, it is not smooth to show that the water tank internal air pressure loses heart, steam bubble rolls in water tank, influences to a certain extent engine cooling Fault Diagnosis and processing.
The model utility content
The utility model, can effectively reduce in the engine cooling and circulating system because high temperature generation bubble is set up a stable case internal pressure in water tank through the special-purpose cooling system swelling water tank of Engine Block Test in order to overcome defective in the above-mentioned existing technology.
The utility model provides a kind of engine-cooling system swelling water tank, and it is a tubular structure, and the cooling water filler is positioned at the swelling water tank bottom, and the swelling water tank top is provided with the spiral reflux condensing tube that can effectively improve the cooling area.
Wherein, the swelling water tank top also is provided with steam gas bleeder valve and the pressure gauge that is used for perception valve pocket pressure.This gas bleeder valve can be according to pressure demand manual tune steam popping pressure, when the water tank internal pressure meets or exceeds setup pressure value, to such an extent as to can reduce the water tank internal pressure by releasing pressure automatically.
Wherein, establish hard-wired Turbogrid plates in the swelling water tank, Turbogrid plates are positioned at 2/3 of swelling water tank highly to be located, and being uniformly distributed with diameter on the Turbogrid plates is that 10mm is with interior through hole; Number of openings can be four.
Wherein, the length of spiral reflux condensing tube is about 10cm.
Wherein, the top of Turbogrid plates is equipped with high-order liquid level sensor, and the Turbogrid plates below is equipped with the low level liquid level sensor.
Compared with prior art, the utlity model has following beneficial effect:
1, the reflux condensing tube at the top changes spiral reflow pipe into by existing straight-through type reflow pipe; Can effectively strengthen the cooling area that high-temperature steam is back to this place; Make high-temperature steam obtain effective condensation at this place, more steaminess is become again liquid form and is back to swelling water tank by gaseous state;
2, through an automatic gas bleeder valve being installed, the automatic removal of partial high pressure that produces in the swelling water tank top design;
3,2/3 eminence of swelling water tank installs Turbogrid plates additional; Be evenly equipped with through hole on the Turbogrid plates; The mode that can effectively prevent the big flow of cooling system cyclic high-temperature water moves back to swelling water tank rapidly, to such an extent as to it is stifled to form gas, influences high-temperature steam and refluxes through reflux condensing tube; Also can effectively cushion and replenish cooling water pressure from the bottom up fast, make the external world can keep metastable case internal pressure when giving the swelling water tank moisturizing.
Description of drawings
Fig. 1 is the utility model engine-cooling system swelling water tank structural representation;
Fig. 2 is the plan view of Turbogrid plates with holes in the utility model swelling water tank.
In conjunction with the accompanying drawing following reference character of mark above that:
The 1-tank box, 11-cooling water filler, the spiral reflux condensing tube of 2-, the automatic gas bleeder valve of 3-, 4-pressure gauge, the high-order liquid level sensor of 5-, 6-Turbogrid plates with holes, 61-through hole, 7-low level liquid level sensor.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
As shown in Figure 1, the engine-cooling system swelling water tank of the utility model comprises tank box 1, and casing 1 is a cylinder-like structure.Casing 1 top is provided with automatic gas bleeder valve 3, pressure gauge 4, and the cracking pressure according to the automatic gas bleeder valve of reading can regulate of pressure gauge 4 satisfies the requirement of research cooling recirculation system build-up pressure.Casing 1 top also is provided with spiral reflux condensing tube 2, and spiral reflux condensing tube 2 is the tubular structure of spring-like shape, and length is about 10cm, with respect to straighttube-type reflux condensing tube of the prior art, can reach better condensing reflux effect.Place, 2/3 high position is fixed with Turbogrid plates 6 with holes in the casing 1; Be uniformly distributed with in the Turbogrid plates 6 and be furnished with 4 through holes about 10mm (three through holes are positioned at three dot locations of equilateral triangle; Another is located at the center portion of equilateral triangle, referring to Fig. 2), aforementioned four 10mm through holes are distributed on the Turbogrid plates 6; Can effectively slow down the recoil of big flow pressure water, set up steady pressure.The top of Turbogrid plates 6 with holes is provided with high-order liquid level sensor 5; The below of Turbogrid plates 6 with holes is provided with low level liquid level sensor 7; Can monitor cooling recirculation system internal liquid demand constantly; When lack of water in the swelling water tank and liquid level arrived low liquid level, system prompt carried out moisturizing (from bottom to top carry out moisturizing from cooling water filler 11 this moment) to water tank, and system stops moisturizing when moisturizing reaches high water level.
The engine-cooling system swelling water tank of the utility model is through installing an automatic gas bleeder valve in the swelling water tank top design; The automatic removal of partial high pressure that produces; Reflux condensing tube at the top changes spiral reflow pipe into by existing straight-through type reflow pipe simultaneously; Can effectively strengthen the cooling area that high-temperature steam is back to this place, make high-temperature steam obtain effective condensation at this place, more steaminess is become again liquid form and is back to swelling water tank by gaseous state; 2/3 eminence of swelling water tank installs Turbogrid plates additional; Be evenly equipped with the through hole of four 10mm on the Turbogrid plates; The mode that can effectively prevent the big flow of cooling system cyclic high-temperature water moves back to swelling water tank rapidly, to such an extent as to it is stifled to form gas, influences high-temperature steam and refluxes through reflux condensing tube; Also can effectively cushion and replenish cooling water pressure from the bottom up fast, make the external world can keep metastable case internal pressure when giving the swelling water tank moisturizing.
The engine-cooling system swelling water tank of the utility model is reasonable in design, can effectively reduce in the engine cooling and circulating system because high temperature generation bubble is set up a stable case internal pressure in water tank; Help engine-cooling system, thermally equilibrated research, reduce the influence of external fault motor.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
