DBY3 Electric diaphragm pump DBY3-15 Aluminium alloy

一、DBY3 Electric diaphragm pump Overview：
   DBY3 electric diaphragm pump,we use cycloidal pin gear speed reducer to drive.The crankshaft crank-mechanism drive double diaphragms to do reciprocating motion.To make the working volume change alternately then the liquid will continue to be inhaled and discharged.The diaphragm material reached a relative breakthrough recent years due to the improvement of materials.at the same time the service life of diaphragm is greatly extended.So it used more and more widely in petrochemical、ceramic and metallurgy and many other fields to replace part of centrifugal pump、screw pump.
   二DBY3 Electric diaphragm pump Features：
   1.Do not need to irrigate water.It can work with electricity.self suction can reach over 3m.
2.Transport more viscous liquid (viscosity below 10000cp)
3.The electric diaphragm pump have no self shaft seal,which can extend the service life greatly.
4.Good passage capacity,the maximum particle is 8mm.Less damage occur to the pump when pump mud and other impurities.
5.Simple structure,less vulnerability parts,easy installation and maintenance.The transmission medium will not contact with connecting rod and bearing,It won’t make the performance go down because of the wearing of rotor and pistons like other kinds of products.
6.working temperature:5~65℃,Medium temperature`-20℃~150℃
7.The diaphragm is separated by the transmission medium and transmission machinery,so the medium will not leak and not affect the environment.According to different mediums,the diaphragms have different materials such as neoprene,fluorine rubber,nitrile rubber,PTFE to satisfy all different customers.
8.The parts where medium passed,according to customers’ different working environments we can use different materials such as cast steel,SS,aluminium alloy,lining fluoride.And the motor also can use common type and explosion-proof type with different powers.
三、DBY3 Electric diaphragm pump Working Principle：
There are two flexible diaphragms in the symmetrical working chamber of the pump, the connection rod combines two diaphragms, the cam equipped in the middle of the square groove of the connecting rod drives the connection rod do Reciprocation.
The motor shaft is connect with an eccentric shaft which front is composed with camshaft and bearing,. The connection rod will do Reciprocation while the motor works.
When the connection rod shaft moves forward left direction, the left chamber in a compressed state, the liquid is squeezed out of the chamber, meanwhile the right chamber in an expanded state, the external liquid is sucked into the chamber; the connection rod moves forward right direction, the right cavity in a compressed state, the liquid is compressed out, and left the chamber in an expanded state, the external liquid is sucked into the cavity, thus achieving a motor driven diaphragm back and forth to work, we will continue outward transport medium.
