1, install the front road to confirm SENMI product performance and medium flow arrow is consistent with the movement conditions, and plug the valve cavity clean, does not allow the seals and disc with foreign bodies attached impurities, not clean before not allowed Close the disc to avoid damaging the seal. 2, the installation of pneumatic butterfly valve flange flange recommended special disc, that is HGJ54-91 socket welded steel flange. 3, pneumatic butterfly valve installed in the pipeline location, the best position for the legislation, but can not flip. 4, the use of pneumatic butterfly valve need to regulate the flow, a pneumatic actuator control. 5, the number of open and close the manual butterfly valve more, in about two months time, open the worm gear box cover, check the butter is normal, should maintain the right amount of butter. 6, check the connection parts of the required compression, that is, to ensure the packing seal, but also to ensure flexible stem rotation. 7, metal seal pneumatic butterfly valve is not suitable for installation at the end of the pipeline, such as must be installed at the end of the pipeline, the need to take the export distribution flange, to prevent the seal backlog, over. 8, the valve stem to install the use of regular inspection of the valve to check the effectiveness of the use, found that the failure to be ruled out in time. Pneumatic butterfly valve sealing surface leakage troubleshooting 1, butterfly plate, sealing surface folder debris 2, butterfly plate, sealing surface close position anastomosis 3, the outlet side equipped with flange bolts force uneven pneumatic butterfly valve leakage at both ends Troubleshooting 1 , On both sides of the gasket failure 2, the pipe flange uneven or uneven compression 3, the seal ring, the next seal failure
Poly Aluminium Chloride
Poly Aluminium Chloride is referred to as PAC. It is also commonly called basic aluminum chloride or coagulant. It is a new type of high-efficiency inorganic polymer flocculant. Its aqueous solution is a hydrolysis product between aluminum trichloride and aluminum hydroxide, with a colloidal charge, so it has a strong adsorption on suspended matter in water. To achieve the purpose of condensing suspended matter in water. The Polyaluminium Chloride produced by Jinhe are white, yellow or light yellow powder.
Polyaluminum Chloride has the functions of removing suspended matter, COD and BOD, degreasing, decoloring, removing heavy metals and residual chlorine in water, etc. It is mainly used for purification treatment of tap water and industrial wastewater. Polyaluminum chloride is currently the most widely used inorganic coagulant in water purification processes. There is no need to adjust the pH value of the source water, it has a wide range of adaptation to the pH value of the source water, which is unmatched by traditional inorganic low molecular coagulants.
Polyaluminium Chloride is used in metallurgical, electric power, tanning, medicine, printing and dyeing, papermaking, chemical and other industries` sewage treatment.It`s also used in tap Water Treatment. Its coagulation effect forms flocs (also known as alum flowers) fast, the particles are large and heavy, and the sedimentation is fast. The applicable PH value ranges from 5 to 9, and has the characteristics of low dosage, low cost, high activity, convenient operation, wide adaptability, and low corrosion.
