Aluminum alloy pneumatic diaphragm pump is a new type of conveying machinery, and it is the most novel kind of pump in China. Compressed air is used as power source, and all kinds of corrosive liquids, granular liquids, high viscosity, volatile, flammable and highly toxic liquids can be pumped away. So here is the analysis of the reason why the aluminum alloy pneumatic diaphragm pump is not out of liquid after starting, what is it?
1, the liquid proportion is too large, or the concentration is too large, the suction distance of the diaphragm pump can not reach, so in this case, the pump in the work, but can not make the liquid;
2, Aluminum Alloy pneumatic diaphragm pump in the pump valve ball and seat seal is not good, the reflux liquid immediately hit back, in this case, the pump body is a liquid, but the flow is very small, very low;
3, the inlet pipe seal is not good, in this case, the pump is normal work, but because the suction can not be liquid, so the pump can not make the liquid.
4, the air inlet pressure of the inlet is not enough. The air source pressure range of the general domestic pneumatic diaphragm pump is generally at 2-7kg, which is larger than or less than the value, and the pump can not work normally.
5, aluminum alloy pneumatic diaphragm pump in the body of the wear parts of the wear, in this case is easier to solve, change the vulnerable parts can; alcohol pump
6, the lowest level of the error is to pump the import and export of the reverse, the pump is imported, export on. The probability of such a mistake is very small, but I have encountered such a customer.
7. The air compressor is too low in the origin of air (normal pressure is 5-7 kg).
8, the pump itself has problems, such as some small workshop produced by the diaphragm pump itself in the factory does not test directly sold to the market, and buy such a diaphragm pump can only be returned to the manufacturers.
