Quick Detail

Work Principle

The hydraulic oil is driven by the reciprocating movement of the plunger, and the hydraulic oil drives the diaphragm to reciprocate to realize the inhalation and discharge of the medium.


 

Feature

◆Diaphragm-limit valve-compensation valve-built-in safety valve mutual linkage automation oil refill and built-in safety protection technology are utilized. The precision of the limit valve can reach ±0.002mm, the surface hardness is up to 60-70HRC, the roughness is up to 0.4μm, and the limit valve can be reused for 80 million times within the temperature range of -80 DEG C to 160 DEG C.

◆PTFE polymer composite diaphragm is utilized, and the diaphragm is subjected to multidirectional roll-in and surface quenching, the homogenization degree reaches 99.92%, which reduces the cold flow phenomenon during operation and improves the compressive strength

◆Built-in safety valve and oil filling valve, automatic exhaust and oil refill, superior and reliable performance

◆The inlet and the outlet utilize high precision one-way valve set, which effectively guarantees the metering accuracy and liquidity

◆Integrated “Oxder” worm gear pair variable speed transmission mechanism with low noise and high efficiency;

◆The patented integrated sleeve adjustable eccentric transmission mechanism is utilized, the structure is simple and reliable, and the travel can be continuously adjusted from 0% to 100%. The metering accuracy is ±0.5%.

◆Oil immersion lubrication, which guarantees long-term and reliable operation of the transmission mechanism;

◆Double-diaphragm or multi-diaphragm may be used when dangerous media, such as toxic medium, flammable and explosive medium and corrosive medium, are transported.

◆Diaphragm rupture alarm device, which prevents the media from contacting the hydraulic oil when the diaphragm breaks;

◆Various flow adjustment type: manual, electrical, pneumatic, and frequency conversion adjustment;

◆Equipped with electrical stroke adjustment mechanism, which can realize remote automatic control;

◆Two or more heads can be connected in parallel, maximum 12 heads; multi pump heads can be used for conveying the same kind of medium to reduce pulse; the multi pump heads also can be used as a proportional pump for conveying multi media.

◆Wide application range, applicable for conveying various media.
