Acid pump selection has always been one of the most troublesome chemical practitioners, a little careless, ranging from damage to equipment, heavy cause accidents and even lead to disaster. So we all know how to acid pump selection? This is a very tricky thing, which needs to be transported according to what acid to determine the type selection, the following is the acid pump selection method introduced. Acid pump selection method 1, hydrochloric acid hydrochloric acid used in the highest concentration of 38%, so the hydrochloric acid pump is basically as long as the overcurrent parts made of plastic on the line, but if from the life, cost and other aspects to consider, Can choose FSB fluorine alloy centrifugal pump or CQB-F magnetic pump, the price of these two pumps, the performance is satisfactory. 2, Sulfuric acid sulfuric acid pump is divided into dilute sulfuric acid pump and concentrated sulfuric acid pump, the former a larger choice, dilute sulfuric acid pump can choose engineering plastic pump, ceramic pump, or F46 pump, F26 pump, the latter (concentrated sulfuric acid pump ) Only Fluoroplastics (F46) pumps can be selected because concentrated sulfuric acid corrodes common engineering plastics while fluoroplastic does not corrode. Also note that the high density of concentrated sulfuric acid, pump power when the pump should pay attention to the allocation of large, simple algorithm for the "shaft power" * 1.84 is the shaft power delivery concentrated sulfuric acid. 3, hydrofluoric acid hydrofluoric acid is very corrosive, it is recommended to use fluorine plastic magnetic pump, (and must be the series of ceramic pump parts replaced by hydrofluoric acid) 4, nitric acid pump also recommended the use of nitric acid Fluorine plastic magnetic pump, and rubber seals to be replaced by PTFE material. 5, acetic acid It is one of the most corrosive substances in organic acids, ordinary steel in all concentrations and temperatures of acetic acid will be severely corrosive, stainless steel is an excellent anti-acetic acid material, 316 stainless steel containing molybdenum can also be suitable for high temperature and Dilute acetic acid steam. For high temperature and high concentration of acetic acid or other corrosive media and other harsh requirements, the choice of high-alloy stainless steel or fluorine plastic magnetic pump. Such as CQB magnetic pump, CQ316L stainless steel magnetic pump 6, brine (seawater) Ordinary steel in sodium chloride solution and seawater, salt water corrosion rate is not too high, the general shall be used paint protection; all kinds of stainless steel also have a low uniform corrosion rate, But may cause localized corrosion due to chloride ions, usually 316 stainless steel is better, but its higher price, it is recommended to use fluorine plastic centrifugal pump, such as IHF chemical centrifugal pump. 7, Sealed seal form: Magnetic pump is a static seal, so you can not consider the sealing, and centrifugal pumps generally use external bellows mechanical seal, the corrosion resistance and wear resistance are better, such as the delivery of the media containing particles, then Hard to hard mechanical seals can be used.

Pneumatic Toilet Tank
Pneumatic Toilet Tank is a high-tech toilet equipment that uses pneumatic technology to control flushing. Compared with traditional mechanical hidden water tanks, it has higher flexibility and reliability.
The pneumatic toilet cistern is mainly composed of a water tank, an air gauge, a cylinder, a water valve and buttons. When the button is pressed, the air gauge will automatically release the compressed air into the cylinder, push the water valve to open and release the water into the toilet basin. When the air in the barometer is completely released, the water valve will automatically close, stopping the inflow of water.
The advantages of the pneumatic toilet tanks include: the amount of flushing water can be adjusted freely, the flushing effect is better, the service life is long, it is easy to clean, and it is more water-saving. It can control the amount of flushing water by adjusting the air gauge, so as to adapt to different toilet basins and flushing requirements. In addition, the pneumatic hidden water tank does not require any buttons or handles to be touched by hand, which also makes it more hygienic.
