Diaphragm metering pump increased with liquid pulse frequency to promote continuous to join

diaphragm metering pump increased with liquid pulse frequency to promote continuous adding diaphragm metering pump is mainly reciprocating metering pump, the pump cylinder number can be divided into a variety of types such as single cylinder, double cylinder, three cylinders. This pump can be widely used in petroleum, chemical, textile, food, papermaking, atomic energy technology, power plants, such as plastics, pharmaceuticals, water plants, environmental protection industry, science and technology department. Diaphragm metering pump used to pressure or precise quantitative atmospheric pressure container and the pipeline conveying liquid containing no solid particles. Diaphragm metering pump flow turns on ( Or machine) From 0 Within the scope of 100% stepless adjustment. （ According to the characteristics of metering pump, minimum travel is generally not less than 10% of the total trip) Single cylinder pump is suitable for the occasion of a single liquid; Duplex pump can be used for proportional pump, and also can be used in parallel; Triplex pump can be used as a proportion of three water pump, can also be three cylinder in parallel, in order to achieve a larger displacement, increase the pulse frequency of the liquid, prompting liquid continuous smooth joining; Six cylinder pump of triplex pump double effect. This type of diaphragm metering pump can supply temperature - 30℃— 80 ℃, the viscosity of 0. 3 - 1000 was a/s corrosive or non corrosive liquid not containing solid particles, medium. A, diaphragm metering pump installation requirements: 1. Diaphragm metering pump spare concrete foundation shall be installed in a special platform, or iron casting land bolt fixed after correction. Concrete foundation shall be higher than the ground 50? More than 100 mm. 2. Diaphragm metering pump suction and discharge pipe diameter should not be less than import and export of pipe diameter, inlet line should be shortened as far as possible. Such as suction pipe passing too long or elbow, should undertake NPSHa business accounting, in order to meet the necessary requirements of net positive suction head. 3. Connecting line should be measuring instrument, such as pressure gauge ( The user should bring along their own) 。 4. End of the suction pipe shall be fitted with filters ( The user should bring along their own) 。 5. Diaphragm metering water pump discharge line shall be provided with a safety relief valve or valve ( The user should bring along their own) 。 If you want to reduce the outlet pressure pulsation, can set the pressure on the road near the pump discharge pipe. 6. Electric control equipment should be installed in the pump as far as possible according to the using situation of work, electrical control equipment should be installed with the medium of the corresponding control switch protection device, in order to ensure safety. 7. Combination of multigang pump ( Piston or diaphragm type) , for the same with the specification, pipe according to the grades of flow pressure, begins with a motor for the fundamental point, pressure from high to low in sequence arrangement; Diaphragm metering pump for seat is the combination of different specifications, different has according to from large to small installation, the user simply piping connections. Second, the diaphragm metering pump: 1, the direct contact with the media parts adopt stainless steel and all four fluorine material. Flow to adapt to the general particles, non-toxic tasteless. 2, diaphragm metering pump, double pump head structure, economical and practical, cover an area of an area small, superior performance. All three, vulnerable parts through specialized processing, quality assurance. 4, internal configuration performance excellence regulator assembly, prolong the service life of pump, and reduce the noise. 5, quantitative output, diaphragm metering pump in the pump can be adjusted when running or stopped traffic, high precision of plus or minus one percent. A series of 6, spit out pressure at up to 500 kg. 7, applicable to transfer temperature - 30? 120 ℃, the viscosity of 0. 3800 was/s medium.
