DBY electric diaphragm pump unknown bitterness behind success

DBY electric diaphragm pump success unknown poignant DBY electric diaphragm pump adopts the cycloidal reducer drive, drive the double diaphragm pump through the crank slider mechanism on reciprocating motion, make changes alternately working volume so as to achieve the liquid suction. At the same time, in recent years due to the diaphragm material and craft made breakthrough progress, is greatly prolong the service life of the diaphragm, thus replacing part of the centrifugal pump, screw pump has been more and more widely applied in petrochemical, ceramics, metallurgy and other industries. DBY electric diaphragm water pump is suitable for low pressure, outlet pressure or less 3 KGF/cm2. DBY electric diaphragm pump product features: 1. Without irrigation water diversion, self-priming ability top 5 meters; 2. Through outstanding performance, under 10 mm in diameter of particle, mud, etc all can effortlessly through; 3. Because the diaphragm is medium and transmission mechanical parts separately, so the media would never leak outward. No shaft seal and pump itself, greatly extend the service life. DBY electric diaphragm pump diaphragm material with according to the nature of the medium choice, can meet the needs of different users; 4. DBY electric diaphragm pump pump body medium flows through the part, according to the requirements of users, can be divided into cast iron, aluminum, stainless steel, rubber lining, lining fluorine material, such as motor is divided into ordinary type, explosion-proof type and speed. DBY electric diaphragm pump with quality and reliable service life is long, the noise, little vibration, corrosion resistance, fine workmanship and so on six big advantages, DBY electric diaphragm pump is the one of the most innovative pump. DBY electric diaphragm pump material is complete, the diaphragm, ball, ball seat using the strong corrosion resistant resilient F46 ( FEP FEP or F46, is a copolymer of tetrafluoroethylene and hexafluoropropylene) Material, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light. DBY electric diaphragm pump power is given by the motor, the motor through reducer drive the fortress of the diaphragm pump body on each column or reciprocating motion. DBY electric diaphragm pump up and down at about two in the pump chamber is equipped with four single ball valve, diaphragm piece about the movement of pump cavity volume change regularly. Forced four single ball valve open and close alternately, which will generate fluid liquid suction and discharge. DBY electric diaphragm pump unique principle and structure of the simple won the general customers consistent high praise main advantages can be summarized as follows: through performance is good, DBY electric diaphragm pump instead of centrifugal pump, slurry pump and impurity pump good through the larger particles impurities, mud, etc. ; Smooth operation, safe and reliable, low noise; Can run no-load, needs no introduction water imbibition, etc. DBY electric diaphragm pump is the one of the most innovative water pump. For all kinds of corrosive liquid, with particles, high viscosity, volatile, flammable, explosive, poisonous liquid, ceramic glaze thick liquid, fruit purees, glue, oil tankers under-bin liquids such as oil recovery, temporary inverted cans can be smoked light. DBY electric diaphragm pump performance parameters and MARIOWPUMPS similar WLLDENPUMPS in Germany, the United States. DBY electric diaphragm pump pump flow components material, stainless steel, aluminum alloy, cast iron, DBY electric diaphragm pump according to different liquid eyes using butyl rubber, fluorine rubber, neoprene, and four kinds of ptfe. DBY electric diaphragm pump adopts, YB Y motor as power source, 3 to 5 m, suction lift 30 m, flow rate of 0. 5-20m3 / h。 DBY electric diaphragm pump way of role only when choosing pneumatic actuators, DBY electric diaphragm pump action through the positive and negative effect and positive effect of the valve actuator portfolio formation. There are four that are positive (combination Gas closed type) , positive and negative, Gas type) And anyway, Gas type) And reflect ( Gas closed type) , through the combination of four DBY electric diaphragm pump action have both on and off. For the choice of the ways of diaphragm pump function, mainly from three aspects: a) Process safety; b) The characteristics of medium; c) Ensure product quality and economic loss is minimal. DBY electric diaphragm pump flow characteristic refers to the relative flow and displacement (medium flow through the valve The valve relative opening degree) The relationship between the ideal flow characteristic mainly has the percentage (such as straight line, Logarithmic) , parabolic and quick opening, etc. 4. Common ideal flow characteristic only percentage (such as straight line, Logarithmic) , quick opening three kinds. Parabolic flow characteristic between straight line and equal percentage, the percentage of properties such as generally available to replace, and quick opening feature is mainly used for two control and program control, therefore DBY electric diaphragm pump characteristic is, in fact, the choice of straight lines and equal percentage flow characteristic of choice. DBY electric diaphragm pump flow characteristic of choice by theoretical calculation, but the method and equation are very complicated. Today use experience more standard, DBY electric diaphragm pump concrete from the aspects to consider: (1) from the regulating quality of the regulating system of the analysis and choice; (2) from the process piping is considered; (3) from the change of the load analysis. Choose good DBY electric diaphragm pump flow characteristic, can according to the traffic characteristics determine the shape and structure of the valve core, but for like a diaphragm valve, butterfly valve, etc. , due to the structural characteristics of DBY electric diaphragm pump, impossible to change the surface shape of valve core to achieve the required flow characteristic, at this time, but by changing the feedback of the valve positioner CAM contour.
