This heavy-duty accumulator piston cup and diaphragma set is specially engineered for e.g. DNB110 and OKB7200 hydraulic rock breakers; widely matched on medium- and large-size excavator crushing equipment. It serves as the core energy-storage sealing component to isolate the nitrogen gas chamber from the hydraulic oil circuit, comprising an integrated piston cup, a thickened diaphragm, and auxiliary sealing gaskets for full accumulator overhaul.
Made of imported high-performance HNBR + modified PPDI composite rubber, the product features outstanding fatigue resistance, high pressure resistance and anti-aging performance. It thoroughly solves common faults such as nitrogen leakage, impact force attenuation, breaker weak striking and frequent oil mixing, effectively extending the service life of breakers under long-term mining, demolition and heavy crushing operations.

Plene dimensie-matc kun la originala Etc. DNB110 e OKB7200 interrompitoroj, konsistanta kun OEM part-numeroj DNB110-DIA, OKB7200-MEM e 3089721001. Neniu modifo necesas por rekta instalo, perfekte konvenas al la interna kavaj strukturo de la akumulatoro.
La centra pistono-kupo e la diafragmo uzas importitan HNBR + PPDI vulkanizitan komponan materialon, kun ultra-alta cikla fatig-rezisto. Ĝi rezistas hidraŭlikan oleon korozion, alta temperaturo malnoviĝon e oftan alt-frekvencan etendiĝon, stabile funkciante en severaj laboraj medioj de -35°C ĝis 135°C.
Ĉiuj partoj sukcese trapasas streĉan 130 MPa alt-preman fatig-ŝok-teston. Ĝi efike blokas nitrogenan forkuradon e oleo-gaso miksiĝon, konservas stabilan akumulatoran energiostokan efikecon, garantias konstantan interrompitoran frapforton e evitas potencmalpliigon dum daŭra rompado.
Integrat omnes accessorios ad sigillationem et ad conservationem energiae, qui sunt necessarii pro manutentione accumulatoris. Unum set complectitur omnes partes ad substitutionem plenam, minuit emptiones secundarias et breviat tempus inoperationis apparatus et impensas manutentionis.
Omnis set membranarum pistonicarum subicitur testibus aeris hermeticitatis, fessurae altae frequentiae et senectutis thermalis antequam ad mittendum, plene satisfaciens standardibus productionis OEM, et praebens stabilem longamque operationem sub oneribus magnis constructionis.
Idoneus pro frangibutoribus hydraulicis, ut DNB110, OKB7200, quae montantur in variis machinis constructionis graviorum:
