Chemical Pump is suitable for chemical, petroleum, metallurgical industry, electric power, paper making, foodstuff, pharmaceuticals and compound fabric industry etc., used for transporting all kinds of corrosive or similar to the medium of water pollution is not permitted. The over-flow parts of the pump are made of metal materials such as stainless steel or non-metallic materials such as fluorine plastic, which are resistant to acid and alkali corrosion. The shaft seal is generally mechanical seal to prevent leakage.

What should you pay attention to when detonating electric detonators?
Pay attention to the following safety precautions when using an electric detonator to detonate:
First, the use of electric detonators must be checked one by one, the electric detonators used in the same blasting network should be the same factory, the same type of products.
2. When the stray current value of the blasting operation site is greater than 30 mA, it is forbidden to use ordinary electric detonator. It should be replaced with anti-stray current detonator or use non-electric detonation method to detonate.
3. Before the main line of the blasting is connected with the detonating power source or the detonator, the total resistance value of the whole line must be determined. The error between the total resistance value and the calculated value is ±5%. If it is not met, the cause should be ascertained, and then corrected.
Fourth, the chamber blasting, the power supply of each chamber should be withdrawn before installing the blaster.
