With a reasonable power to buy farm machinery

Power matching the power machine mainly refers to power and speed to meet the needs of mechanical support . Power is to describe how much mechanical work done per unit of time , expressed by kw ; speed is the rotational speed of the power machine shaft , commonly r / min expressed .knapsack power sprayer  The size selection is based on the power machine power production machinery needs identified . If the power machine rated power selected too large, will increase investment costs , big horse cart wasting energy ; rated power if the power machine choose small, appeared with fixed or overloaded , damaged power machine , shortened life expectancy and even damage the power machine . Therefore, according to the actual needs of production machinery and working methods , through scientific calculations, in order to select the appropriate power machine power . For the province , generally small-scale farmers to choose the power machine , the selection according to the following criteria : If agricultural production machinery and the motor is a direct drive , the selected motor power should be dragged mechanical power of 1.0 to 1.1 times ; if agriculture machinery and motor is the result of belt drive , the selected motor power should be dragged mechanical power of 1.05 to 1.30 times ; engine supporting agricultural machinery should be equal to the power required 1.3 to 1.5 times. Optional powered farm machinery required speed as much as possible with the speed of the same or close , because it can be installed directly used agricultural machinery , because speed is inconsistent, in order to meet the requirements , you must refit the transmission equipment, fruit tree sprayers increase the number of charges .

If there are some agricultural households power equipment in advance , it should give full play to the role of existing power machine , in the purchase of new agricultural machinery , we should try to consider power machine capable of matching the original , except for special needs , in general, do not each machine is individually furnished one kind of power machine , so that it costs too much, management is not easy .
