Description
Technical field
The invention belongs to technical field of engines, specifically, the particularly water circulation system of motoring machine frame.
Background technology
At present, after the engine assembling is rolled off the production line, all need carry out the break-in bench test, with the performance of detection of engine.When carrying out the break-in bench test, need the practical working situation of simulated engine, therefore need to connect the water circulation pipe of engine.As shown in Figure 2, existing way is that a water tower 13 is set on the next door of break-in stand, and this water tower 13 is connected with engine 1 through inlet tube and outlet tube, and the interior water inflow engine of water tower like this flows back in the water tower after taking away heat again.Because the chilled water of flow direction engine is the tap water of normal temperature, temperature is lower, and tap water gets into after the engine, causes the engine section parts to be out of shape because of quenching easily or damages, thereby influence the performance and the serviceable life of engine.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of can effectively prevent engine component impaired break-in stand water circulation system in cooling procedure.
Technical scheme of the present invention is following: a kind of motoring machine frame water circulation system; Comprise engine (1), thermostat (2), supercharge pump (3), first solenoid valve (4), first three-way connection (5), return pipe (6), second three-way connection (7), second solenoid valve (8), electric valve (9), water inflow of the engine pipe (10) and engine water outlet (11); On engine (1), be provided with engine water inlet (1a), the bolt hole that discharges water (1b) and engine water delivering orifice (1c); The outside of engine (1) is provided with thermostat (2); The liquid outlet of this thermostat (2) is connected through pipeline behind supercharge pump (3) and first solenoid valve (4); Be connected with first interface of first three-way connection (5); Second interface of first three-way connection (5) is connected with the liquid return hole of thermostat (2) through return pipe (6), and the 3rd interface of first three-way connection (5) passes through pipeline and is connected with first interface of second three-way connection (7), and second interface of second three-way connection (7) is connected through pipeline and is divided into two-way behind second solenoid valve (8); One the tunnel is connected with electric valve (9); Another road is connected with the bolt hole that discharges water (1b) of engine, and the 3rd interface of second three-way connection (7) is connected with engine water inlet (1a) through water inflow of the engine pipe (10), and said engine water delivering orifice (1c) is connected with the inlet of thermostat (2) through engine water outlet (11).
Adopt above technical scheme, when carrying out the test of motoring machine frame, the thermostat on the engine is opened; First, second solenoid valve is also opened, and the water in the thermostat flows out from liquid outlet under the effect of supercharge pump, is divided into two-way through first three-way connection; One the tunnel flows back to thermostat through return pipe, plays pressure release, to prevent that supercharge pump pressure is excessive and cause conduit failure; Another road in discharge water bolt hole and engine water inlet inflow engine, cools to engine respectively through second three-way connection; Flow back to thermostat through engine water outlet then, form the water route circulation.Thermostat is incubated processing to the water of its inside; Make the water of flow direction engine maintain the temperature at 50-60 ℃; The chilled water in the inflow engine and the temperature of engine interior are unlikely to differ greatly especially like this; Thereby prevented that effectively the engine section parts are out of shape because of quenching, avoided the engine component damage, guaranteed the performance and the serviceable life of engine.
After the engine break-in finished, with the supercharge pump and second closed electromagnetic valve, connected tracheae on the electric valve this moment; Blow through this tracheae; Make gas get into engine interior, in-engine chilled water is blown out from the engine entery and delivery port, chilled water is got back in the thermostat through the bolt hole that discharges water; Can prevent residual moisture in the engine like this, guarantee that the cooling water channel of engine interior keeps dry, clean.The engine that test finishes is pulled down from stand, reinstalled another engine and connect pipeline, can carry out next running-in test, not only convenient but also quick.
On said thermostat (2), be provided with liquid spill-way, this liquid spill-way is connected with the water inlet of water tower (13) through liquid overflow pipe (12), and the water delivering orifice of water tower (13) is connected with the interior ball-cock assembly (15) of thermostat (2) through liquid supplementation pipe (14).Liquid level in the ball-cock assembly control thermostat, when liquid level is lower than setting value, ball-cock assembly is opened, and makes water tower pass through liquid supplementation pipe moisturizing in thermostat; When if the water in the thermostat is too many, unnecessary water flows into water tower from liquid overflow pipe and stores.
Between said liquid overflow pipe (12) and engine water outlet (11), be connected with by-pass pipe (16); Be in series with the 3rd solenoid valve (17) on this by-pass pipe (16); Like this test finish blow water in, also can the 3rd solenoid valve be opened, the water that engine is blown out flows directly in the water tower.
On said thermostat (2), be provided with leakage hole, this leakage hole is connected through pipeline behind first hand valve (18), is connected with by-pass pipe (16).First hand valve is opened, can the water in the thermostat all be bled off so that with thermostat is cleaned; The water that bleeds off flows in the water tower through by-pass pipe, can prevent water resource waste.
On the liquid supplementation pipe (14) of said water tower (13), be connected to the cooling liquid supplementation pipe, this cooling liquid supplementation pipe is connected behind the 4th solenoid valve (19), is connected with the cooling fluid infusion mouth of thermostat (2).When the water temperature in the thermostat was too high, the 4th solenoid valve was opened, and in thermostat, replenished cold water, and the water temperature in the thermostat in time is reduced in the numerical range of setting.
On the liquid supplementation pipe (14) of said water tower (13), be connected to manual liquid supplementation pipe, this manual liquid supplementation pipe is connected behind second hand valve (20), is connected with the manual fluid infusion mouth of thermostat (2).Operating personnel also can open the moisturizing cooling in thermostat of second hand valve as required, and are very convenient.
On said return pipe (6), be in series with the 3rd hand valve (21).Through regulating the 3rd hand valve, can adjust water yield size, to satisfy the needs of different situations to the thermostat backwater.
Beneficial effect: the present invention forms the cooling water channel circulation system through setting up thermostat and engine; Can prevent effectively that engine component is impaired in cooling procedure; Not only guaranteed the performance and the serviceable life of engine, and the data of break-in test are had more with reference to property.
