Last time, I tried Charlie's brushless DC brushless water pump. Went to pump groundwater (8 meters deep).. Pump 2 "Charlie's solar cells worked well. But I came to notice that the water gushing out had stopped the province. Not filling the pipe rhythmically And the water doesn't go as far as it should.
I came to think of the words of Krisada Charoonsri, another independent inventor. that has invented a new check valve To solve the problem of suction heads that are commercially available. which still has many disadvantages such as valve cups obstructing the water causing the water to not fill the pipe And there is still a spring to pull back again. consume motor power Waste of electricity, waste of oil, and the skull itself is still flaring, making it difficult to go down the underground pipe, having to drill for a lot of size Much more than the pipe we will use.
So I drove to Khun Krisada to Min Buri, Nong Chok to explain the working principle of the check valve called "Carburetor check valve" And ask you to try with Charlie's solar cell water pump the next day.
