Low noise, high pressure variable displacement piston pumps PH series

Transcription

1 1-1 Low noise, high pressure variable displacement piston pumps PH series The PH Series is a low-noise variable displacement piston pump with rated pressure of 28 MPa. This series was developed based on the low-noise P**V seris which has won high reputation from various customers. The PH Series also feature lower noise levels, and more compact size. Superior controllability: in addition to pressure compensator control, load sensing control, and electric direct control, torque limiter control is also offered.

Specifications Model Code PH8 PH1 PH13 Maximum PH17 17 Working MPa Rated 28 Intermittent 3 Rated 21 Intermittent 22.5 Maximum Minimum Weight Speed Speed kg min -1 min Intermittent refers to intermittent pressure which operable time is limited to 1 of operating cycle (max. 6 seconds). Consult Tokyo Keiki for working pressure above rated pressure. Rated pressure of electric direct control EDHS is 21 MPa. This pressure is limited by safety valve setting. Weight is for CH type (pressure compensator control). Consult Tokyo Keiki for specifications of pumps using water glycol fluids.

2 Pump control method (PH series) Pump Control Method Name compensator control Code CH Characteristics Curve Setting pressure Description When pump delivery pressure approaches the compensator setting, pump delivery is automatically reduced to the minimum flow necessary to maintain the pressure. setting can be adjusted manually. Function Symbol (detailed) A 1-2 Remote pressure compensator control CGH Setting pressure of pressure compensator control can be set from a separate location with a remote control valve. compensator safety relief valve integrated. setting can be adjusted manually. Remote control Setting pressure Vent port Load sensing control CVH Remote control Setting pressure Pump delivery automatically controlled to maintain constant differential pressure across flow control valve located downstream of pump. Energy-saving type pump control which supplies minimum flow and pressure necessary to drive load (actuator). compensator safety relief valve integrated. setting can be adjusted manually. Remote pressure compensator control possible with externally installed remote control valve. A vent port should be connected to the hydraulic circuit. Torque limiter (low torque/high torque) TL/TH Remote control Setting pressure Pump delivery automatically controlled to match load capacity of the electric motor. Flow setting can be manually adjusted. compensator safety relief valve integrated. setting can be adjusted manually. Remote pressure compensator control possible with externally installed remote control valve. Electric direct control EDHS In flow control mode, pump delivery is controlled by flow control signal and as pump delivery pressure approaches the pressure setting signal, mode automatically switches to pressure control. Special controller necessary. compensator safety relief valve integrated. setting can be adjusted manually. Maximum displacement adjustment function D Maximum displacement adjustment with adjustment screw on pump. adjustment symbol
