Problems solved by technology
This method has the following two deficiencies: ①The two water pumps are switched completely by human manipulation. During construction, the operator usually forgets to switch regularly, but waits until the main water pump is found to be broken, and then switches to the standby water pump
Therefore, the sprinkler motor cannot be effectively protected.
② The driving power of the sprinkler motor is frequently loaded and unloaded on the motor in the form of switching values, and this frequency is usually a few seconds between start and stop. The sprinkler motor is also easily damaged if it runs under this working condition for a long time

Embodiment Construction
[0043] Such as figure 1 As shown, the implementation steps of the sprinkling control method of construction machinery in the embodiment of the present invention are as follows:
[0044] 1) Set up at least two water pumps;
[0045] 2) Set the sprinkling amount and the pump switching time used to control the working time of each pump;
[0046] 3) Select at least two normal water pumps;
[0047] 4) During construction, the selected water pumps will be started in turn according to the water sprinkling amount and the switching time of the water pumps to carry out watering operations.
[0048] Among them, during the sprinkling operation in step 4), the currently activated water pump is detected in real time. If the currently activated water pump fails, the water pump is first marked as faulty and an alarm signal is output, and then judged according to the number of remaining normal water pumps. If the number of remaining normal water pumps is more than two, return to step 3); if ...

The invention discloses a sprinkling control method and a device for engineering machinery. The method comprises the following steps: setting at least two water pumps; setting the sprinkling amount and the water pump switching time for controlling the work time of each water pump; selecting at least two normal water pumps; and starting the selected water pumps in turn according to the sprinkling amount and the water pump switching time so as to carry out the sprinkling operation. The device comprises a control unit (1), a sprinkling amount adjuster (2) which is used for controlling the sprinkling amount, a water pump unit (3), a parameter storage module (4) which is used for storing the water pump switching time and a water pump detection unit (5) which is used for detecting the work state of the current water pump. The sprinkling control method and the device for engineering machinery have the advantages of being high in automation degree, simple for operation, long in service of motors of the water pumps, convenient for debugging and low in cost and realizing the synchronous walking of engineering machinery.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a water sprinkling control method and device for construction machinery with a water sprinkling function. Background technique [0002] When construction machinery such as road rollers are rolling asphalt materials for paving, the steel wheels are likely to adhere to the asphalt materials, which will damage the flatness of the compaction, and even stop the construction of the road roller when the stickiness is severe. The current general solution is to sprinkle water on the surface of the steel wheel to form a thin water film on the surface of the steel wheel, which can effectively prevent the asphalt material from adhering to the surface of the steel wheel. However, when sprinkling water, if the water is too much, the temperature of the asphalt will drop too fast, which will affect the quality of paving construction; A hard mark is formed, which also affects the quality of...
