Abstract
The utility model discloses a running-in test device for an engine. The running-in test device for the engine is provided for overcoming the deficiency that the current transportation department has no special engine running-in device to carry out no-load running-in on repaired engines, and cannot reach the condition requirements of the actual operation. A power generator is installed on a bottom rack capable of installing the engine. A power output shaft of the engine can be connected with a main shaft of the power generator. A variable resistor is connected to a power supply line of the power generator. Since the engine can be connected with the power generator, the engine drives the power generator to generate power when the engine is operated, and the variable resistor connected to the power supply line of the power generator consumes the electricity, so that the engine is operated under loading. The artificial changing of the rotating speed of the engine and the resistance of the variable resistor can simulate the actual operation condition running-in of the engine, and realizes the loaded operation running-in of the repaired engine. The above device has a simple structure, can carry out combined installation by using the current equipment, is low in investment and fast in effect, and is convenient for popularization and application.
Description
Technical field
The utility model belongs to the repairing auxiliary equipment, and is specifically a kind of to carrying out the device of bringing onto load break-in after the engine reparation.
Background technology
The transport of port and pier is very busy, and large-scale lifting and the haulage vehicle utilization factor used in the transport are quite high.In order to guarantee normally carrying out of transport, very important to the daily maintenance of lifting and transportation equipment, particularly more to extraordinarily take good care of the engine of equipment.The engine of lifting and haulage vehicle will place under repair and maintain after operation a period of time, also will carry out break-in to the simulation of engine actual operating mode after the reparation and process, and could prolong its serviceable life.
Because the special-purpose break-in equipment price of engine is expensive, and transportation department is not the maintenance depot of specialty, if be equipped with the specialized equipment of above-mentioned costliness, its utilization factor is relatively low to cause waste.Present transportation department does not dispose above-mentioned specialized equipment mostly, therefore can only carry out the no-load running break-in to the engine after repairing.But the no-load running break-in can not embody the actual operating mode of engine, also just can't reach real engine break-in requirement.If can reduce its serviceable life and break-in is bad.Therefore, how not having in the situation of special-purpose running-in device, the engine after repairing is carried out the bringing onto load break-in, is the problem that needs at present solution.
Summary of the invention
Technical problem to be solved in the utility model is, overcome existing transportation department and mostly do not have special-purpose engine running-in device, to the unloaded break-in of the engine after repairing, do not reach the shortcoming that its actual operating mode requirement reduces serviceable life, a kind of running-in testing apparatus of engine is provided.
The problems referred to above that exist in order to solve prior art, the utility model is to adopt following technical proposals to realize: on the underframe that engine can be installed generator is installed, the power output shaft of engine can be connected with the main shaft of generator, is connected with variohm in the supply line of generator.
The utility model also has following technical characterictic:
Described variohm is by a plurality of parallel connections, the single resistor of gauge tap forms separately;
On described underframe, be supported with the guidance panel that to control and to show described engine and generator operation data;
On described underframe, be supported with the air exhaust muffler device that can be connected with described waste pipe mouth.
In the time need to carrying out the bringing onto load break-in to the engine after repairing, first engine is fixed on the described underframe, again the main shaft of described generator and the output shaft of engine are linked together, variohm is connected on the feed circuit of generator.The starting engine running drives the generator generating, and the electricity that generator sends is supplied with resistor and carried out energy consumption.With the method for the resistance sizes of the rotating speed of control engine and variohm, come the simulated engine actual operating mode to carry out the bringing onto load break-in.
Advantage of the present utility model and good effect are, because the power output shaft of engine can be connected with the main shaft of generator, be connected with variohm on the feed circuit of generator, when engine running, drive the generator generating, the variohm that is connected on the feed circuit of generator consumes electric energy, make the running of engine bringing onto load, change artificially the resistance sizes of rotating speed and the variohm of engine, get final product the actual operating mode of simulated engine, reach the break-in requirement to engine, do not having in the situation of special-purpose running-in device, can realize greatly to prolong the serviceable life of engine to the engine bringing onto load break-in after repairing.
Above-mentioned running-in machine is simple in structure, can utilize existing equipment to make up installation, comes the simulated engine actual operating mode to carry out the bringing onto load break-in, small investment, instant effect, but in the large scale application of amateur maintenance depot.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, on the underframe 2 that can fixedly mount engine 1 generator 7 is installed, the power output shaft of the main shaft of generator 7 and engine 1 links together with ring flange 5.Starting engine 1 running can drive generator 7 generatings, and variohm 8 is connected in the supply line of generator 7.Change the rotating speed of engine 1 and the resistance sizes of regulating variohm 8, get final product the actual operating mode of simulated engine 1, engine is carried out bringing onto load running break-in.
Described variohm 8 is comprised of the single resistor of a plurality of parallel connections, because resistor is to consume electric energy, the on-off of single resistor can be controlled separately with switch, turns off or opens single resistor, can change the load of engine 1.
On described underframe 2, be supported with guidance panel 6 with support 6.1, button and the multiple test instrumentation of 7 operations of operation engine 1 and generator are installed, the relevant test data in the time of can directly reading engine 1 with generator 7 operation from the guidance panel 6 on the guidance panel 6.Like this, not only can control the engine 1 after repairing is carried out bringing onto load running break-in, but also the engine 1 in using can be installed on the underframe 2, come for example power of test engine 1 whether to descend, descend what etc. multiple performance, whether need to keep in repair with definite engine 1, and definite level of repair, reliable basis provided for formulating repair schedule.
For to engine 1 bringing onto load break-in or test the time, reduce the noise pollution of 1 pair of environment of engine, on described underframe 2, be supported with the sound suppressor 4 that can be connected with the exhaust pipe mouth 3 of described engine 1 with pole 9.
