Abstract

The invention discloses an elastic constant-pressure liquid supply device. A fixed support is a rectangular rigid frame; a guide rail respectively consists of two parallel channel-shaped steel girders the notches of which are opposite, is fixed in the middle of the fixed bracket and vertical to the left lateral surface and the right lateral surface of the fixed bracket; a plunger type cylinder isa cylindrical hollow cylinder with a bottom; a plunger is a rod piece with a rectangular front half and cylindrical rear half; the plunger is directly arranged in the plunger type cylinder; and a fixed support seat of the plunger type cylinder is a circular lantern ring, respectively sleeved on the outer walls of the front end and the rear end of the plunger type cylinder and connected with the outer wall of the plunger type cylinder. A connecting rod supporting seat and a guide rod supporting seat are fixed on the left side wall of the fixed bracket along a horizontal line; the left end of the connecting rod is articulated with the connecting rod supporting seat through a connecting rod fixed rotating shaft; a limiting shaft brush is clamped between two rectangular rods of a connecting rod and sleeved on the connecting rod fixed rotating shaft; and the right end of the connecting rod is articulated with the plunger through a connecting shaft. The invention has reasonable and simple structure and convenient operation, realizes constant-pressure liquid supply and can be used for soil seepage tests and earth pillar leaching tests.

Description

technical field

[0001] The invention relates to the technical field of experimental measuring instruments, in particular to an elastic constant pressure liquid supply device, which provides a constant pressure supply device with stable pressure and long-term operation without power supply for scientific experiments such as soil seepage test and soil column leaching test. liquid device. Background technique

[0002] Hydraulic experiment is a kind of basic physical mechanics experiment, and it is one of the main research methods of hydraulics and seepage mechanics research, and a complete set of constant pressure liquid supply device is the necessary equipment for hydraulic experiments.

[0003] At present, the commonly used liquid supply devices are generally float type and self-overflow liquid supply devices, which are relatively popular liquid supply devices, and their functions are relatively single, which cannot meet the test accuracy requirements in the fields of scienti...
