Problems needing attention in the operation of garden humidification pump


The garden humidification pump is also used to better contribute to the garden maintenance. If there is any problem in use, it should be checked in time to avoid the expansion of the problem and affect the safe use of the pump.

The water pump in operation needs to be shut down for inspection. Check whether various instruments work normally, such as ammeter, voltmeter, vacuum gauge and pressure gauge. These values can help us find out the problem more quickly. If the reading is too large or too small, we can find out the cause in time and then solve it.

During the operation of the water pump, the tightness of the packing is appropriate. If the gland is too tight, it will not play the role of water sealing, lubrication and cooling. If the packing is too loose, the water seepage will increase, causing a large amount of water leakage. The air enters the water pump and affects its use. This is also a concern in the work.

In addition, it is also necessary to pay attention to the bearing temperature of the garden humidification pump, which is generally controlled at 30-40 ° C and will not exceed 60-70 ° C. if the bearing temperature is too high, it indicates that the lubrication is invalid, and the lubricating oil can be added again.
