Motors may be used as retarders but
not as hydraulic brakes. When a motor
is used as a retarder, adequate
pressure must be provided at the inlet
port to prevent cavitation. Systems
requiring positive holding capabilities
(braking) must be provided with
externally operated mechanical holding
devices.
The maximum pressure obtainable in
a system using a motor as a retarder
(pumping) is dependent upon speed.
At speeds below 1000 r/min, maximum
obtainable pressure is proportionally
diminished relative to speed as speed
approaches stall.
這些馬達,壓力至 138 bar (2000
psi),轉速至 2800 r/min,扭矩有 2.0,2.8
或 4.0 Nm/6.9 bar (18,25 或 35 lb.in./100
psi ),法蘭或腳架安裝,油口位置可選。
對于 M2U 和 M2-200 馬達,通常轉速能
夠到 50 至 100 r/min,取決于馬達的規
格和所驅動負載的特性。對于 25M-50M
馬達,較轉速一般是 100 r/min,允許
更一些的轉速,取決于要求的扭矩和所驅動負載的
Consult your Vickers representative
before using motors as retarders, or if
braking is required.特性。
M2-200 Standard Models
Back pressure must not exceed: 75% of
supply pressure at 1800 r/min; 80% at
1200; 85% at 600. (Supply and back
pressures are actual operating
pressures at the ports of the motor.) In
circuits where back pressure exists, a
relief valve is required in both the inlet
and outlet ports.
M2U 馬達僅一個方向工作,在訂貨時必須
規定旋轉方向。M2-200 馬達通過使馬達油
口的流量反向,就能簡單地實現反向旋轉。
較轉速能夠在 50 和 100 r/min 之間變
化,取決于馬達的規格和驅動負載的特性。

馬達失速扭矩范圍是對于給定的跨越馬達
壓差下,在 1200 r/min 工作扭矩的 65%
