Abstract
The invention relates to a full-load reliability testing device for a plunger pump. The full-load reliability testing device is formed by a rack, a steering mechanism, a pulley force decreasing mechanism, a balancing weight, a pressure sensor and a human-computer interface. The plunger pump is used as a detected component and mounted on the rack through a second end cover. A steering cylinder is mounted on the rack through a first end cover. The steering cylinder and the plunger pump are connected through a hydraulic steel pipe, so that a closed hydraulic loop is formed between the plunger pump and the steering cylinder. Hydraulic oil is pushed by the plunger pump downwards, the direction of outputting output force of a piston rod is made to be perpendicular to a work table board all the time through the steering cylinder, and the output force is decreased after passing through the pulley force decreasing mechanism. At the tail end of the pulley force decreasing mechanism, large pressure can be obtained on the hydraulic loop only through extremely small pulling force and serves as the load of the plunger pump. The full-load reliability testing device has the beneficial effects that the large load can be provided by the device, the pressure of the hydraulic loop can be adjusted, the maximum output pressure can be 30 Mpa, and the full-load reliability of plunger pumps of different types can be detected.
