高粘度齿轮泵并不能产生压力,它只是输出流量。压力低或无压力,说明高粘度齿轮泵没有吸入液体或泄漏严重。
High viscosity gear pump does not generate pressure, it is only the output flow. Pressure is low or no pressure, high viscosity gear wheel pump don't inhale the liquid or leakage is serious.
普通齿轮泵具有结构简单、成本低、对油液污染不敏感等特点,但具有流量脉动大、径向力不平衡、噪声高等缺点。
The common gear pump has such merits as simple structure, low cost, insensitive oil pollution, etc. but it has such demerits as high flow pulsation, unbalanced radial force, strong noise, etc.
