Product Description Brief Description of vacuum pump liquid
ringYH500 Diaphragm Vacuum Pump is a kind of variable volume type
vacuum pump, and is a new type with excellent functions and high
quality after improvement on the basis of learning merits and
eliminating shortcoming of similar products at home and abroad.
YH500 Diaphragm Vacuum Pump's rotating speed≥1390r/min; input
power≤550W; ultimate vacuum is 700Kpa; volume flow is 40L/min. This
pump can be widely used in experiments of vacuum filtration, rotary
evaporator, refrigeration, dryness, vacuum concentration and
molecular distillation.Working principle of YH500 diaphragm vacuum
pump:The motor shaft is sheathed with an eccentric wheel, one end
of the connecting rod is sheathed on the eccentric wheel, and the
other end is connected with the soft membrane. With the rotation of
the motor to drive the connecting rod for reciprocating motion. The
rod is driven diaphragm which fixed on the pump body to do recycle
motion, to generate elastic deformation, so that pumping chamber
volume changed periodically. In the pump body, there are an inlet
and an exhaust valve, inhale when the volume becomes large, exhaust
when the volume becomes small, thereby reach the purpose of pumping
gas.Product Features of YH500 Diaphragm Vacuum Pump:1.There is
filtering material in the gas exchange position, thereby ensuring
the cleanness of air;2.Working without medium, so no oil vapor
pollution, is the ideal equipment to obtain clean vacuum;3.New
technology and new materials are used in the production process, it
is easy to move and work smoothly, thus ensuring the ideal vacuum
degree and the higher air flow rate;4.Using non friction of the
film body movement, no heat, no friction loss. Diaphragm uses
imported rubber, corrosion resistance, long service life;5.Pressure
adjustable design, can meet a certain range of vacuum and gas flow
rate;6.The bearings use imported classic bearings, smooth running,
low noise, high efficiency.Product DisplayTechnical
