1. The difference between internal reflow/reflow/intelligent type
Answer: There is a reflux device on the top of the reflux type. After reaching a certain pressure, the pressure can be relieved by means of reflux without suffocating the tube. The internal return does not have this function.
The intelligent pump has a pressure switch on the top. When the handle of the sprayer is closed, the pump will stop working. It has the function of turning off the gun and saving electricity and energy.
2. No water? Has the water in the pump been used by someone else?
A: Make sure to remove the two caps first, and each water pump will be tested to see if it is qualified before delivery, and the water pump will be better preserved.
3. How to connect the diaphragm pump?
Answer: The same color wires are connected together, the pump is not divided into positive and negative poles, just connect to the 12V power supply. Power requirements: generally 5a adapter, battery 8ah can be.
4. How much V is the water pump is it a self-priming pump?
Answer: Our water pump uses DC 12V electricity (12V battery or 12V adapter can be used) is a self-priming pump that puts the water in the water inlet pipe and the water pump directly absorbs water.
5. The difference between the internal return water pump and the external return water pump intelligent water pump?
Answer: The so-called backflow is that during the working process of the pump, the inside of the pump is decompressed, which will not damage the pump and the pipe. The difference between the internal return and the external return is that there is a screw on the top of the external return pump head to adjust the return pressure, which can adjust the return pressure, intelligent The pump is to close the pump outlet, the pump will stop working, and then the water will work automatically when the water is turned on. There is a pressure switch inside (the water pressure cannot be adjusted).
6. The pressure of the pump. Suction. Head.
Answer; the pressure of the pump is 4--6 kg, the suction height is 1 meter, and the lift is 5--8 meters.
