Abstract
The utility model discloses a waterway monitoring water tank of a bed frame of an engine test machine, which comprises an air release valve, a water tank, a magnetic-suspension liquid level sensor, a water inlet connector, a sensor mounting seat and an air release valve mounting seat. When the waterway monitoring water tank of the bed frame of the engine test machine is used in test of the engine, the engine is prohibited to run in the case that air in the waterway is not exhausted completely according to technological requirements. The waterway monitoring water tank of the bed frame of the engine test machine has small volume, simple operation and low cost, and is beneficial to operation and maintenance of users.
Description
Technical field
The utility model relates to a kind of engine test-run a machine stand water route monitoring water tank, particularly monitoring engine water route emptying air whether.
Background technology
When engine carried out performance adjustment, deaeration was answered in the engine water route, otherwise can engine running take place the time because of lack of water causes the water pump dry grinding, finally cause the water pump seal water leakage fault.
At present whether the water circuit system of engine test-run a machine stand does not detect the monitoring means of emptying air, easily causing careless omission to cause water pump to damage.
CN200820093776.2 discloses a kind of engine rig test ICS intercooler system, the temperature control system that comprises heat exchanger and control heat exchanger, heat exchanger is the middle cool-heat-exchanger with air intake opening and gas outlet, also be provided with the recirculated cooling water case in the heat exchanger outside, have the water inlet and the water delivering orifice of input chilled water on the described water tank.This ICS intercooler system does not have to consider that when next engine of test water circuit system may take place enters air and the problem of initiating failure.
Summary of the invention
At the deficiencies in the prior art, the monitoring water tank in stand water route when the utility model provides the engine test-run a machine, when monitoring engine does not have emptying water route air when carrying out performance adjustment, then cut off the engine start control loop, lack of water causes the fault that the water pump dry grinding finally causes water pump seal to leak when avoiding engine running.
The utility model engine test-run a machine stand water route monitoring water tank comprises air release, water tank, the floating sensor of liquid level magnetic, water supply connector, sensor mount pad and air release mount pad, air release is installed in water tank upper by the air release mount pad, water supply connector is installed in the water tank bottom, and the floating sensor of liquid level magnetic is installed in tank top by the sensor mount pad.
The utility model engine test-run a machine stand water route monitoring water tank, used the magnetic float liquid level sensor, permanent-magnet steel is housed in the magnetic float, magnetic float fluctuates with the variation of liquid level, causes magnetic pole to connect when magnetic float rises to the sensor position of magnetic pole and has been equivalent to connect a contact switch of often opening.The auxiliary reclay series connection of this normally opened contact switch control is arranged in the engine start control loop.
The utility model engine test-run a machine stand water route monitoring water tank, for easy to use and monitoring have been adopted in water tank bottom water inlet top venting, water tank is anhydrous or water is not full situation in the time of can preventing to operate next engine again, plays the phenomenon of certain strick precaution waterless operation operation engine.
Because adopt technique scheme, the utility model has produced following beneficial effect:
This practical engine test-run a machine stand water route monitoring water tank, simple to operate, realized that engine does not have emptying water route air then to cut off the engine start control loop when carrying out performance adjustment, lack of water causes the water pump dry grinding finally to cause the water pump seal water leakage fault when avoiding engine running.

Embodiment
Monitoring water tank in the utility model engine test-run a machine stand water route directly monitors the emptying air whether when engine water route system, and then control auxiliary reclay to action, realization engine start loop forms to open circuit when the lack of water of water route and does not allow to operate engine running.
Below in conjunction with accompanying drawing, a kind of embodiment of the utility model is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.
As depicted in figs. 1 and 2, be respectively the utility model engine test-run a machine stand water route monitoring cisten mechanism figure and control principle figure, comprise magnetic supernatant liquid level sensor, air release 1, water tank 5 and auxiliary reclay K2 etc.2 series connection of liquid level sensor terminals insert the auxiliary reclay control loop.
During the engine test-run a machine, stand water route monitoring water tank will link up warm braw valve or vent connection on water tank bottom water supply connector 6 and the engine outfall sewer with sebific duct when using, and makes the engine water route communicate with water tank; Open engine test-run a machine stand water route monitoring water tank air release handle 8 during the front-seat water route of engine running air, air by water tank air release emptying engine water route system, there is air in system as the engine water route, then liquid level sensor float 4 can't float → liquid level sensor K1 (normally opened contact switch) then can't closure → auxiliary reclay K2 can't adhesive → auxiliary reclay K2 normally opened contact can't be closed → press in the engine start control loop starting button K3 then engine can't start.
As engine water route system emptying air → then then closure → auxiliary reclay K2 adhesive of liquid level sensor float 4 come-up → liquid level sensor K1 (normally opened contact switch) → auxiliary reclay K2 normally opened contact closure → press starting button K3 in engine start control loop engine start then.
The auxiliary reclay K2 that passes through of the utility model engine test-run a machine stand water route monitoring water tank controls the engine start loop, is convenient to check and safeguard; When water tank can fine strick precaution be operated next engine by adopting the air release venting of water inlet top, bottom, the employee arrange engine water route air and has just piloted engine and cause the water pump seal lack of water to dry grind to cause water leakage fault.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
