The chemical industry is full of corrosive and hazardous chemicals. Although these media play a key role in the relevant industries, they pose a serious challenge to pump equipment. The more corrosive the process fluid is, the greater the wear on mechanical parts, which in turn leads to more frequent maintenance, higher cost of ownership, and even potential safety hazards. Therefore, pump manufacturers must fully understand the specific characteristics of the fluids they handle to ensure that the right materials are selected for the pump.

First, it should be clear what kind of fluid is being handled

This question seems simple, but it is often overlooked in actual applications. Different fluids have very different corrosive properties (for example, the materials required to transport water are far less demanding than those required to transport hydrochloric acid).

 

Second, it is necessary to confirm whether the fluid contains solid particles

As these particles will increase the corrosion rate.

 

Third, consider the concentration of the fluid

This parameter has a significant impact on corrosiveness. Using hydrochloric acid as an example, 100% hydrochloric acid is less corrosive than 36% hydrochloric acid due to the higher reaction rate at the lower concentration.

 

The fourth and final critical factor is fluid temperature

Temperature changes can significantly alter the reaction rates in the fluid, accelerating the corrosion process. Knowing these characteristics and accurately communicating them to the manufacturer helps users obtain a canned motor pump that is suitable for their specific conditions while avoiding unnecessary material investments. Table 1 lists three examples that cover the potential range of corrosivity.

	Minimally corrosive	Corrosive	Highly corrosive
Fluid	Water	Anhydrous hydrochloric acid	Hydrochloric acid
Temperature	Normal temperature (75°F)	Normal: -14°F, Operating: 100°F	200°F
Concentration	100%	100%	36%
Solid particles	Contains	Contains	Contains

Table 1: Examples of potential corrosive ranges

 

Once the above parameters are determined, the end user can provide the information to the pump manufacturer, who can then make key material selections. The selection of wet-end components is particularly critical. The so-called "wet-end" refers to those parts that are in direct contact with the process fluid. Some wet-end components corrode at a higher rate than others, which is related to the fluid flow rate they are subjected to (for example, the impeller, as the component that transmits rotational energy to the fluid, usually has a higher flow rate than parts such as bearings or rotors). Therefore, the selection of wet-end materials is the most complex and needs to be adjusted according to the actual corrosiveness of the process fluid.

Another important decision that the pump manufacturer needs to make is the selection of "tank" material. The tank is the main pressure boundary component that contains the process fluid and must be strong enough to withstand the operating pressure while allowing the electromagnetic field to be transmitted from the stator to the rotor. The electromagnetic field is generated by the stator and drives the rotor to rotate, which is the basis for the operation of all induction motors. Therefore, nickel-chromium-molybdenum alloy (also known as C-276 alloy) has become the first choice for tank material due to its excellent strength and corrosion resistance. Although this material is critical, since most canned motor pumps are made of this material, the material selection is relatively uniform and less restrictive.

Now that we have identified the fluid information that the end user needs to provide and why it is necessary, we can analyze specific real-life application cases with the help of the three fluid situations in Table 1.

The first example is water without solid particles at room temperature (75°F)

This fluid is extremely non-corrosive and has a wide range of wet-end materials to choose from. The most common material for canned motor pumps is 304 stainless steel, which is an economical and durable metal material. Some manufacturers even recommend the use of plastic materials such as nitrile rubber or polypropylene. As mentioned earlier, the tank body is generally made of C-276 alloy, which is also the standard configuration of most canned motor pumps.

 

The second example is 100% anhydrous hydrochloric acid, which has a wide operating temperature range (-18°F~68°F)

Although hydrochloric acid itself is highly corrosive, its overall corrosiveness is relatively low due to its extremely high concentration and low temperature. Therefore, the selection of 316 stainless steel can effectively deal with the corrosion risk under this condition.

The most corrosive liquid mentioned in Table 1 is hydrochloric acid at a concentration of 37% at 200°F. This condition combines the two factors of high temperature and low concentration that aggravate corrosion, posing a great challenge to the material. For most alloys, high-temperature hydrochloric acid will not only accelerate the corrosion of the metal, but also further induce secondary corrosion of the metal by water.

Under such extreme conditions, it is difficult to find a standard metal material that can meet the corrosion protection requirements. Therefore, manufacturers often choose special materials such as armor with excellent corrosion resistance. In addition, in order to protect the motor components, a clean water flushing circulation system is also used to prevent damage to the C-276 tank and bearing materials. Although such applications require higher material costs, they are necessary investments to ensure the long-term stable operation and safety of the pump.

Material selection may seem complicated, but it is actually a key step in maximizing pump performance. For the end user, although the task seems simple, it is crucial. A deep understanding of your application requirements and full communication with the pump manufacturer are the first steps to a successful selection. If this step is not performed properly, resulting in distorted information about fluid properties, the design basis of the entire pump will be biased. As a pump manufacturer, it is necessary not only to fully understand the user's actual application environment, but also to clearly understand the interaction between these conditions and the existing materials. The key is to ensure that the selected materials can handle the most severe operating conditions while taking into account the economical design.

Can a vision counter be used for multiple purposes?

Can a vision counting machine count multiple materials? The answer is yes.

There are two meanings of one machine for multiple uses. One is that for materials of similar size in the same industry, they can be counted. The other is that for materials of similar size in different industries, they can also be counted by using the same model.

1.Different materials in the same industry
Take the hardware industry as an example. Different types of screws or other hardware can use the same equipment. Perhaps for enterprises with a dozen or more materials, only one counting device can be used to count all materials. Moreover, our vision counting equipment also has a learning-free function. You can directly pour the materials on the counting machine hopper and our counter will count them immediately, which greatly improves the efficiency of the operation. It reduces the difficulty of operating the machine, which is especially convenient for companies that need to frequently switch materials.

2.Materials in different industries can use the same equipment
Usually the same industry does not use materials from other industries for counting. But for the counting equipment manufacturers, this kind of universal equipment is very important. Such as the bottle cap, zipper, and screws of the corresponding size. Such a multi-purpose machine can not only meet more industries, easy to scale production, for the reduction of production cost is also very helpful.

Vision counting machine helps you solve the problem of expensive labor

With the increasing of labor costs, many enterprises began to find ways to save labor costs.

The customer said that they have 8-10 people in the counting and packaging process, and the packaging quality is also unstable. Therefore, they want to seek professional automatic vision counting machine that can reduce some labor for other links and improve packaging quality. Finally, after detailed demand docking, a customized vision counting machine was built based on the customer's packaging requirements, speed requirements and product characteristics.

The customer uses manual material collection and is equipped with a foot switch for discharging materials. If there are 30 pieces/package, the counting machine can reach 25 packages/minute.

If the speed requirement is fast and the budget is sufficient, an automatic packaging machine can be equipped with a signal docking with the counting machine to achieve full automation of counting and packaging.

We can do some calculations and see how the vision counting packaging machine can help you solve the problem of expensive labor.

Before customer use counting machine: according to the 8 people, packaging 2 people, the average one person can complete 2.5 packages a minute, then 8 people can complete 20 packages a minute. In 8 hours a day, 9600 packets a day.

After using our automatic vision counting packaging machine, according to the counting and packaging speed of 25 packages/minute, 2 people are required, one to load the finished product and the other to pack the finished product. To complete 9600 packages, it only takes 6.4 hours. The manual labor saves 6 people. If the salary is 60,000 RMB per year, the counting and packaging process can save 360,000 costs per year.

In addition, there are some hidden benefits:
1. If there is a shortage of quantity in manual packaging, it may cause customer complaints, affect the corporate image, and may lead to a reduction in order volume.
2. Since the vision counting machine will not be short of quantity, it can ensure packaging quality and customer satisfaction, and the corporate image is improved.
