Double-cylinder alternate operation manual pump

The utility model discloses a double-cylinder alternate operation manual pump, and relates to the technical field of pressure test detection equipment. The plunger pump comprises a pump body, a fluidchannel, a plunger set, a connecting rod set and a fluid control valve set, a high-pressure cylinder and a low-pressure cylinder of the pump body are communicated in a non-series-connection mode through the fluid channel, so that the connecting rod set is allowed to drive the plunger set to alternately operate, the water injection pressure rising speed is increased, the pressing resistance is reduced, and the whole manual operation process is more time-saving and labor-saving. 本实用新型公开了一种双缸交替运作手动泵，涉及试压检测设备技术领域。本实用新型包括泵体、流体通道、柱塞组、连杆组以及流体控制阀组，其中，泵体的高压缸和低压缸通过流体通道非串联的连通，以允许连杆组带动柱塞组交替运作，加快注水升压的速度并降低打压阻力，使整个手动操作过程更省时省力。
