Description
Technical field
The utility model is related to a kind of pump cover structure for pressure test, belongs to pump cover pressure testing field.
Background technology
Pressure testing to pump housing flow passage part, is inspection casting quality, checks the important step of casting defect.Traditional handicraft is to pump
Pressure testing, after needing all to machine pump cover, the pump housing, by pump cover and pump housing assembling completing pressure testing.However, pump cover and pump
Body is typically respective batch machining, if after individually processing pump cover, it is necessary to ability assembling pressure testing after waiting the pump housing also to machine,
Cause the test product for failing to assemble to be detained in a large number, increased inventory cost.In addition, carrying out pressure testing survey after pump cover and pump housing assembling
Examination, if a certain test part is unqualified, in addition it is also necessary to dismantles pump cover and the pump housing, easily makes qualified parts that spiral shell can occur
Line dropout etc. is damaged, and increases the labour intensity of workman.
Utility model content
The purpose of this utility model is to need the together pressure testing of the pump housing, pump cover, meeting to the pressure testing of pump to solve traditional handicraft
Cause the test product for failing to assemble to be detained in a large number, and easily make qualified parts that spiral shell can occur when dismantling rejected part
Line dropout etc. is damaged.
The purpose of this utility model is achieved through the following technical solutions：
A kind of pump cover structure for pressure test of the present utility model, including pressure testing mold, pump cover pressure ring, machine capping plate, pressure gauge, pipe
Line；
Pressure testing mold is that one end is with the end columnar structured, cannelure at the internal diameter of pressure testing mold and pump cover lower end outer
External diameter matches, and the depth of inner cavity of pressure testing mold is more than the external diameter of cannelure at the outer of pump cover lower end；
Pump cover pressure ring is the annular slab matched with the external diameter of pump cover lower end annular boss；
Machine capping plate is to seal the plectane that matches of shape in the through hole of position with pump cover upper terminal, be provided with machine capping plate water injection hole and
Pressure test hole；
Machine capping plate loads in the through hole of pump cover upper terminal envelope position, and is bolted, the water injection hole on machine capping plate
Pressurized water is connected by pipeline, the pressure test hole connection pressure gauge on machine capping plate, and machine capping plate seals position with pump cover machine
Through hole is sealed by sealing ring；The inner chamber of pressure testing mold is inserted in the lower end of pump cover, and pump cover is by the cannelure at its lower end outer
With the axial direction screens of pressure testing mold, make to leave feed liquor cavity between pump cover outer lower surface and the interior bottom of pressure testing mold, and outside pump cover
Sealed by sealing ring between edge and pressure testing mold inwall；Pump cover pressure ring covers the upper end in pump cover outer, pump cover pressure ring and pressure testing
By screw-driving between the outer of mold, pump cover pressure ring and pressure testing mold is made to step up pump cover.
During pressure testing, the pressure gauge on machine capping plate is unloaded, the water injection hole on plate is covered by pipeline slave and is noted into pump cover
Water, when there is the continual spilling of water in the pressure test hole that machine is covered on plate, is again loaded into pressure gauge, and continues into pump cover
Water filling, until manometric reading reaches test pressure value, checks that pump cover has ne-leakage, visible deformation and abnormal noise etc..
Beneficial effect
Pump cover structure for pressure test of the present utility model, simple structure are easy to operate, test structure reliability, it is achieved that to pump cover
Independent pressure testing, reducing wait the pump housing to machine after machining because of pump cover and be detained time of production scene.
Description of the drawings
Structural representations of the Fig. 1 for the utility model pump cover structure for pressure test；
Wherein：1- pressure testing molds, 2- pump cover pressure rings, 3- machines capping plate, 4- pressure gauges, 5- pipelines.
Specific embodiment
With reference to the accompanying drawings and examples content of the present utility model is further described.
