Abstract
The invention relates to the technical field of engineering machinery and particularly relates to a pump pressure test drainage pipe tooling. The tooling is characterized in that a drainage pipe and an inflation rubber pipe are arranged, and the drainage pipe is formed by a large-inner-diameter drainage pipe body, a small-inner-diameter drainage pipe body and a transition pipe body. The large opening end of the transition pipe body is communicated with the large-inner-diameter drainage pipe body, the small opening end is communicated with the small-inner-diameter drainage pipe body, and axes of the large-inner-diameter drainage pipe body, the small-inner-diameter drainage pipe body and the transition pipe body coincide. The side wall of the transition tube body is in cross communication with the inflation rubber pipe, and an air outlet of the inflation rubber pipe is corresponding to the large opening end of the transition pipe body. Due to the structure, the tooling has the advantages of being simple in structure, capable of performing pressure test conveniently, time saving and labor saving, capable of improving the labor efficiency and the like.
Description
Technical field
The present invention relates to technical field of engineering machinery, specifically a kind of pump housing pressure testing waste pipe frock.
Background technique
SLTX desulfuration recycle pump is one of Te Beng division department major product, its pump housing material is two phase stainless steel MS11 or high abrasion cast iron Cr30A, heat treatment hardness is generally HRC58-62, during pump housing pressure testing for this desulfuration recycle pump product, dewatering orifice is not designed during design, need when pressure testing to carry out pressure testing test in the sidewall boring of the pump housing, because its material is special, hardness is high, hole very difficult, therefore after pressure testing completes, in the pump housing, there is a large amount of ponding, these ponding got rid of then more difficult.
Leave the problem of ponding discharge difficulty after completing, adopt bernoulli equation principle, design pressure testing draining frock, can be time saving and energy saving be drained by pump housing internal water accumulation, saves man power and material, raises labour efficiency.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, pressure testing convenient, time saving and energy saving, the pump housing pressure testing waste pipe frock of raising labour efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pump housing pressure testing waste pipe frock, it is characterized in that being provided with waste pipe and inflation sebific duct, described waste pipe is by large diameter waste pipe, little internal diameter waste pipe and transition tube composition, transition tube big opening end is connected with large diameter waste pipe, osculum end is connected with little internal diameter waste pipe, and large diameter waste pipe, the axis of transition tube and little internal diameter waste pipe matches, transition tube sidewall intersects with inflation sebific duct and is communicated with, the big opening end of the corresponding transition tube in air outlet of described inflation sebific duct, when pressure testing, pump housing internal water accumulation connected by little internal diameter waste pipe, blowoff basin connected by large diameter waste pipe, inflation sebific duct external compressed air, according to Bernoulli's equation principle, when connecting pressurized air, one high velocity air can be formed at jointing, air-flow is larger, local pressure is less, ponding residual in the pump housing is by the effect of atmospheric pressure, under the effect of inflating air-flow in sebific duct, can automatically along little interior next on waste pipe, flow in blowoff basin through transition tube and large diameter waste pipe, ponding remaining in the pump housing is discharged very soon.
Inflation sebific duct of the present invention and the little interior angle through waste pipe are 20 °-50 °, act on smoothly to reach draining.
The present invention, owing to adopting said structure, has that structure is simple, pressure testing convenient, time saving and energy saving a, advantage such as to raise labour efficiency.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference character: large diameter waste pipe 1, little internal diameter waste pipe 2, transition tube 3, inflation sebific duct 4.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of pump housing pressure testing waste pipe frock, it is characterized in that being provided with waste pipe and inflation sebific duct 4, described waste pipe is by large diameter waste pipe 1, little internal diameter waste pipe 2 and transition tube 3 form, transition tube 3 big opening end is connected with large diameter waste pipe 1, osculum end is connected with little internal diameter waste pipe 2, and large diameter waste pipe 1, the axis of transition tube 3 and little internal diameter waste pipe 2 matches, transition tube 3 sidewall intersects with inflation sebific duct 4 and is communicated with, the big opening end of the corresponding transition tube 3 in air outlet of described inflation sebific duct 4, when pressure testing, pump housing internal water accumulation connected by little internal diameter waste pipe 2, blowoff basin connected by large diameter waste pipe 1, inflation sebific duct 4 external compressed air, according to Bernoulli's equation principle, when connecting pressurized air, one high velocity air can be formed at jointing, air-flow is larger, local pressure is less, ponding residual in the pump housing is by the effect of atmospheric pressure, under the effect of inflating air-flow in sebific duct 4, can automatically along little interior next on waste pipe 2, flow in blowoff basin through transition tube 3 and large diameter waste pipe 1, ponding remaining in the pump housing is discharged very soon.
Inflation sebific duct of the present invention and the little interior angle through waste pipe are 20 °-50 °, act on smoothly to reach draining.
Embodiment 1: a kind of pump housing pressure testing waste pipe frock, it is provided with waste pipe and inflation sebific duct, described waste pipe is by large diameter waste pipe, little internal diameter waste pipe and transition tube composition, transition tube big opening end is connected with large diameter waste pipe, osculum end is connected with little internal diameter waste pipe, and large diameter waste pipe, the axis of transition tube and little internal diameter waste pipe matches, transition tube sidewall intersects with inflation sebific duct and is communicated with, the big opening end of the corresponding transition tube in air outlet of described inflation sebific duct, described inflation sebific duct and the little interior angle through waste pipe are preferably 30 °, when pressure testing, pump housing internal water accumulation connected by little internal diameter waste pipe, blowoff basin connected by large diameter waste pipe, inflation sebific duct external compressed air, according to Bernoulli's equation principle, when connecting pressurized air, one high velocity air can be formed at jointing, air-flow is larger, local pressure is less, ponding residual in the pump housing is by the effect of atmospheric pressure, under the effect of inflating air-flow in sebific duct, can automatically along little interior next on waste pipe, flow in blowoff basin through transition tube and large diameter waste pipe, ponding remaining in the pump housing is discharged very soon.
The present invention, owing to adopting said structure, has that structure is simple, pressure testing convenient, time saving and energy saving a, advantage such as to raise labour efficiency.
