Abstract
A loading test method of a lawn mower includes the following steps: step one, a motor of a lawn mower is installed on a dynamometer machine so as to measure rotation speed of the motor under different loading conditions when a speed controller of the motor is located at a normal working gear and draw a speed regulation characteristic curve of the motor; step two, the motor is taken down from the dynamometer machine, the motor is installed on the lawn mower according to a normal ex-factory state of the lawn mower, and other corresponding elements of the lawn mower are regulated to the ex-factory state; and step three, the lawn mower is arranged in a pool with water until the rotation speed of the motor reaches the working state set by the lawn mower, and the working state is obtained according to the speed regulation characteristic curve drawn in the step one until required durability tests are completed. Compared with the prior art, the loading test method of the lawn mower cannot be limited by seasons and weather, simultaneously can be operated indoor, greatly lowers labor intensity of test staff, and simultaneously can greatly reduce test cost.
Description
Technical field
The present invention relates to a kind of hay mower load test method.
Background technology
Hay mower (abbreviation lawn machine) supporting engine and relevant gearing are mainly examined in the long duration test of hay mower, the method of the actual test of mowing of usual employing, but because place limits during actual tests, be difficult to find enough large lawn for test; Also be subject to seasonal restrictions the lawn not having availability test in the winter time, mow to test due to reality needs to carry out in outdoor simultaneously, and this test often needs to carry out in the season of heat, and the condition of work of testing crew is severe, and labour intensity is large.
Summary of the invention
Fundamental purpose of the present invention is the shortcoming overcoming prior art, provides a kind of not by the hay mower load test method that season, weather condition affect.
The present invention adopts following technical scheme:
A kind of hay mower load test method, comprises the steps:
Step one, is arranged on dynamometer machine by the engine of lawn machine, measures the rotating speed of engine when its speed regulator is in normal operation range in different loads situation, draws out the speed regulation characteristic of engine;
Step 2, takes off engine from dynamometer machine, and state when normally dispatching from the factory by lawn machine, is arranged on engine on lawn machine, and factory state is adjusted in other corresponding preparation of lawn machine;
Step 3, the pond that a water level can regulate is set, lawn machine is placed in pond, regulate water level, make water level lower than the cutter of lawn machine, pilot engine, then engine governor is set to operation range, slow adjustment water level, water level is risen to and tool contact, now water will become the load of lawn machine under the disturbance of lawn machine cutter, engine speed is monitored while water level raising, continue water level raising, until engine speed reaches the lawn machine duty of setting, this duty obtains according to the speed regulation characteristic drawn out in step one, until complete required endurancing.
Rotating speed when engine is in peak torque is also measured out in described step one, and test at maximum engine torque rotating speed point in described step 3: regulate water level, rotating speed corresponding when making engine be in peak torque, lawn machine is remained on stable operation under this peak torque state, until complete required endurancing.
In described step 3, the size in pond is advisable can put into lawn machine.
From the above-mentioned description of this invention, compared with prior art, a kind of hay mower load test method of the present invention by the restriction of season, weather, also can not carried out in indoor simultaneously, greatly reduce the labour intensity of testing crew, greatly can reduce experimentation cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the trystate structural representation of specific embodiment of the invention when lawn machine being placed in pond, and number in the figure representative is as follows: pond 1, water 2, cutter 3, lawn machine 4;
Fig. 2 is the speed governing curve schematic diagram of the specific embodiment of the invention, and in figure, horizontal ordinate is engine speed, and left ordinate is moment of torsion, and right ordinate is power.
Embodiment
Describe the present invention below by way of embodiment.
See figures.1.and.2, a kind of hay mower load test method of the present invention, comprises the steps:
Step one, is arranged on dynamometer machine by the engine of lawn machine, measures the rotating speed of engine when its speed regulator is in normal operation range in different loads situation, draws out the speed regulation characteristic of engine; Also measure out rotating speed when engine is in peak torque simultaneously
Step 2, takes off engine from dynamometer machine, state when normally dispatching from the factory by lawn machine, is arranged on by engine on lawn machine 4, and factory state is adjusted in other corresponding preparation of lawn machine 4;
Step 3, the pond 1 that a water level can regulate is set, the size in pond 1 is advisable can put into lawn machine 4, lawn machine 4 is placed in pond 1, the water level of water 2 in balancing tank 1, make water level lower than the cutter 3 of lawn machine 4, pilot engine, then engine governor is set to operation range, slow adjustment water level, water level is risen to contact with cutter 3, now water will become the load of lawn machine 4 under the disturbance of lawn machine cutter 3, engine speed is monitored while water level raising, continue water level raising, until engine speed reaches lawn machine 4 duty of setting, this duty obtains according to the speed regulation characteristic drawn out in step one, until complete required endurancing, and test at maximum engine torque rotating speed point: regulate water level, rotating speed corresponding when making engine be in peak torque, lawn machine is remained on stable operation under this peak torque state, until complete required endurancing.
Above are only a specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
Claims (3)
