Abstract

The invention relates to a pressure testing device for a sheath, and belongs to the field of fluid machinery. The device includes a bottom plate, a side plate, a top plate, a split-half inner ring, aside-plate clamping ring, a booster pump and a pressure boosting pipe. The top plate and the bottom plate are disposed at upper and lower end ports of the sheath. The top and bottom plates are clampedtightly and sealed through studs. The side plate is mounted outside a lateral outlet of the sheath. The rear end of a port connection stage of the lateral outlet of the sheath is sleeved with the split-half inner ring and the side-plate clamping ring. The side-plate clamping ring and the side plate are fastened through screws and nuts. The device achieves tests on actual pressure of a separated sheath component, and can effectively control blank quality of the sheath. Complete machine assembling before pressure testing is not needed, thus increasing the pressure testing efficiency and reducing component retention time.

Description

technical field [0001] The invention relates to a sheath pressure testing device, which belongs to the field of fluid machinery. Background technique [0002] The pressure test of the main flow parts of the heavy-duty slurry pump is an important process to check the quality of the casting, the defect of the blank, and the pressure of the casting. If the traditional process needs to carry out the pressure test, the sheath, the front guard plate, the rear guard plate, the front pump casing and the rear pump casing must be assembled before proceeding. For the sheath connected to all parts in the heavy-duty slurry pump, if the pressure test fails, all parts need to be removed and the sheath replaced to increase the test work intensity; and because each part is processed in batches, the processed sheath needs to be The pressure test can only be done after all other parts are processed, and the waiting time for the pressure test is prolonged, so that a large number of parts are s...
