Germany Kaiser imported pneumatic diaphragm pump common technical problems
Germany Kaiser imported pneumatic diaphragm common technical problems The imported pneumatic diaphragm pump in Germany does not need water, the suction stroke is up to 7m, the lift is up to 50m, the product lift can reach 70m, the outlet pressure is ≥7kgf/cm2; the flow is spacious, the pass performance is good, and the diameter of the large particles is allowed to reach 10mm. When the mud and impurities are pumped, the pump wears little; the lift and flow can be adjusted steplessly by the valve opening (the air pressure is adjusted between 1-7kgf/cm2); the pneumatic diaphragm pump has no rotating parts and no shaft seal. The diaphragm completely separates the pumped medium from the moving parts of the pump and the working medium, and the delivered medium does not leak outward. Therefore, when pumping toxic, easy-to-use or corrosive media, it will not cause environmental pollution and harm to personal safety; it does not need electricity, it is safe and reliable to use in flammable and explosive places; it can be immersed in the medium; it is easy to use and reliable. It is only necessary to simply open and close the gas valve. Even if there is no medium running or sudden stop due to unexpected conditions, the pneumatic stainless steel diaphragm pump will not be damaged. If the load is overloaded, the pump will automatically stop and have self. Protection performance, when the load returns to normal, it has automatic start-up operation; the structure is simple and the wearing parts are few. The pneumatic stainless steel diaphragm pump has simple structure, convenient installation and maintenance, and the medium conveyed by the pump will not touch the valve, linkage Such moving parts, unlike other types of pumps, have a gradual decline in performance due to wear of rotors, pistons, gears, blades, etc.; they can transport relatively viscous liquids (viscosities below 10,000 centipoise); the pump does not need to be lubricated with oil Even if it is idling, it has no effect on the pneumatic stainless steel diaphragm pump. Explanation: The pressure of the air supply is too high, causing the diaphragm to be broken; the inlet is blocked or the valve is installed, causing the diaphragm to crack due to vacuum in the pump chamber. Explanation: Compressed air contains impurities and moisture. After a long time, impurities will accumulate in the valve chamber, which will wear the V-ring and O-ring inside, causing the pneumatic diaphragm pump to not work. Adjust the intake pressure to avoid Excessive pressure pulls the diaphragm; the added oil can lubricate the valve chamber. Explanation: During the delivery process, the slider inside will shift and need to be manually reset. The specific operation method is as follows: the gas valve cover is opened, and the two black small sliders inside are turned back and forth, one is placed on the left side, the other is placed on the right side, and the gas valve cover is installed (the valve cover screw is not required to be screwed too much) tight). Explanation: This situation may be caused by the ball valve wear and the ball valve and the ball seat are not well sealed, and the accessories need to be replaced. In addition to the cause of wear, it is necessary to check whether there is any leak in the feed pipe. If the pump is in the working process, the feed pipe will have air in, and the pump will not suck the material. Explanation: Install the pneumatic triple piece, keep the air source pressure within the normal range; keep the feed port unblocked, do not install the valve; filter the filter every time the pump is finished, especially when it is more viscous or viscous material. Explanation: The pressure of the air source is too small. In addition to the pressure of the air compressor itself, the distance of the air pipe should be shortened as much as possible. Because the air pipe is too long, the compressed air will be consumed, and the actual air pressure will not reach the rated requirement.

Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
Urinalysis test strips with single-layer membrane structure and multi-layer membrane structure.
