has purchased hydraulic valves from for 6 years, and has cooperated with in several non-standard hydraulic cartridge valves. Some time ago, some customers complained that their logistics transmission equipment was not easy to operate. After the after-sales inspection, it was found that the hydraulic cartridge relief valve on the rotary device failed to buffer and the pressure regulation was not smooth. The original manufacturer said that this hydraulic cartridge relief valve was benchmarked to the standard parts of HydraForce, and he was unable to optimize. contacted me and asked me how to make the hydraulic cartridge relief valve easy to adjust pressure and have buffering function. According to the hydraulic schematic diagram and the original hydraulic cartridge relief valve drawing provided, engineer found that the requirements can be met as long as the original structure is improved. After 35 days, sent 20 samples of hydraulic cartridge relief valves. Last week, Clinton sent a PO for 200 hydraulic cartridge relief valves. He said that when hydraulic cartridge relief valve was installed, the customer no longer complained. It not only provided convenient pressure regulation and effective buffering, but also improved the stability of the equipment. They planned to replace the whole batch of equipment with hydraulic cartridge relief valves. hydraulic cartridge relief valve, the spool, buffer piston and pressure regulating valve housing cooperate to achieve buffer overflow effect, and the overall performance is reliable and stable, mainly from 3 unique structures: 1. The valve housing is provided with a first oil port, and the valve seat is provided with a second oil port. The valve spool can move axially, and the front end cooperates with the rear port of the valve seat to control the on-off between the second oil port and the first oil port. The channel port in the front end of the valve spool is provided with a plug, and the plug is axially provided with a damping hole. The front end face of the valve spool is equipped with a filter screen, and the front pressure surface of the valve spool is larger than the rear pressure surface. 2. The inner cavity of the front end of the pressure regulating screw nut has a buffer piston, and the rear end has a guide part. The radial bulge in the middle forms a convex ring part. The axial opening in the front end matches with the rear end of the valve spool. The oil supply in the middle of the convex ring part is with the connecting channel outside the rear end. 3. The pressure regulating screw is hollow at the rear end of the valve spool to form an inner cavity, which can move axially and change the axial force of the spring. The inner cavity wall of the front end of the pressure regulating screw is matched with the front end face of the convex ring to limit the buffer piston to move forward.
Tris, or tris(hydroxymethyl)aminomethane, has been widely used as a pH buffer in biological media for about 35 years. The near-ideal properties of this biological buffer are the reason for its popularity. Tris does not absorb water, is easily soluble in water, and has high purity. It does not precipitate calcium salts, is stable in solution for several months at room temperature, and does not seem to inhibit many enzyme systems. However, due to the chemical and physical properties of Tris buffer, improper use may lead to erroneous pH measurement of the electrode system. The influence of pH in TRIS buffer on electrode Biochemists use TRIS buffers to control the pH within the physiological range (approximately 7 to 8 pH), because phosphate can cause adverse reactions with biological substances in the test sample. However, when pH measurements are to be made on these solutions, another type of "adverse side reaction" must be recognized, involving the pH electrode system. The influence of chemical and physical properties of Tris buffer on pH Tris, which is commonly used for physiological measurement (pH 7 to 7.5), does not have a large buffer capacity. Therefore, caution should be exercised when using tris buffer to control sample pH. The rather large temperature coefficient of tris (-0.028pH/ C) is also worth considering. For example, if the meter is calibrated with tris buffer and the tris temperature is 20 C, using a pH value of 25 C will cause errors. Therefore, temperature pH dependence must be used when using tris for standardization. When using tris to control the pH of the sample, the degree of control will depend on the sample temperature. If the sample temperature changes by 2 C, the pH control changes by about 0.06 pH units. The required pH control will determine the maximum allowable temperature fluctuations. Advantages of Tris buffer Because the Tris base is highly alkaline, this buffer system can be used to prepare buffers with a wide range of pH values from acidic to alkaline; It has little interference to the biochemical process, and does not precipitate with calcium, magnesium ions and heavy metal ions. Disadvantages of Tris buffer The pH value of the buffer is greatly affected by the concentration of the solution. The buffer is diluted ten times, and the pH change is greater than 0.1; the Tris buffer should be prepared from high-purity tris and HCl using distilled or deionized water without CO2. The temperature effect is large, and the temperature change has a great influence on the pH value of the buffer, so it must be prepared at the use temperature, and the Tris-HCl buffer prepared at room temperature cannot be used at 0 C to 4 C; It is easy to absorb CO2 in the air, so the prepared buffer should be tightly sealed; This buffer has a certain interference effect on some pH electrodes, so use an electrode compatible with Tris solution.

In biological experiments, there is a very important pH stabilizing reagent, which is the biological buffer caps. In the experiment, we usually choose the appropriate weak acid and its conjugated base to get the appropriate pH value. In a large number of experiments, it has been proved that most biological reactions occur under neutral conditions. Generally, the pH value is between 6-8, and the effective buffer range of buffer is between 6-8. Therefore, the acid-base form of buffer should not chelate with some metal ions. Caps, also known as 3-cyclohexylaminopropanesulfonic acid, is a kind of biological buffer, which can be used for enzyme chemistry and HPLC separation of basic drugs. The appearance is white crystal or powder, caps can be dissolved in water, pH buffer range is 8.9-10.3, pKa value is 9.6, molecular weight is 243.28, CAS number is 1135-40-6 below 25 â??. Desheng bio has been developing and producing biological buffer for many years, and has rich experience. Caps is the core product, which is highly praised in the field of biochemical diagnostic reagents and the market of new paint products. Desheng has been established for decades. The company's products are sold to more than 100 countries around the world. The product quality is good and the price is more favorable. If you are interested, you can call us.

Copper(ii) acetate is odorless and efflorescent. It is soluble in alcohol and slightly soluble in ether and glycerol. Copper acetate has many applications, including as a fungicide, insecticide as well as applications in electrolysis and electroplating. Copper(ii) acetate, also referred to as cupric acetate, is the chemical compound with the formula cu(oac)2 where oac, is acetate (ch3co, 2). The hydrated derivative, which contains one molecule of water for each cu atom, is available commercially. Anhydrous cu(oac)2 is a dark green crystalline solid, whereas cu2(oac)4(h2o)2 is more bluish-green. Since ancient times, copper acetates of some form have been used as fungicides and green pigments. Today, copper acetates are used as reagents for the synthesis of various inorganic and organic compounds.Copper acetate, like all copper compounds, emits a blue-green glow in a flame
