Wherein, described water injection hole and described exhaust port are tapped hole.
The utility model is for verifying that the instrument of water pump seamless has following beneficial effect:
After water pump entirety has been assembled, use instrument of the present utility model can test to the sealing of water pump, check that water pump is with or without leakage point, check that there is No leakage at mechanical sealing parts or the O RunddichtringO place of water pump, if there is leakage, then leakage point is keeped in repair, avoid water pump is transported to run on-the-spot after find water pump exist leak and again by water pump from running the on-the-spot situation being transported to Overhaul site and carrying out overhauling, avoid the repeatability maintenance of water pump, reduce the risk that water pump is damaged in repeated maintenance process, decrease economic loss, improve the quality of water pump maintenance.
Accompanying drawing explanation
Fig. 1 is that the utility model is for verifying the structural representation of the instrument of water pump seamless;
Fig. 2 is that the utility model is for verifying the using state schematic diagram of the instrument of water pump seamless.
Embodiment
The technical solution of the utility model is introduced below in conjunction with accompanying drawing.
As shown in Figure 1, for verifying that the instrument of water pump seamless comprises barrel 10, plug 15 and pressuring pump 14.Barrel 10 is the cylinder-like structure of one end open, and the opening end of barrel 10 is provided with flange 11, and the end face of this flange 11 is provided with gasket seal.The sidewall of barrel 10 is provided with water injection hole 13 and exhaust port 12, and water injection hole 13 and exhaust port 12 are positioned at on the straight line of the axis being parallel of barrel 10.Pressuring pump 14 is connected with barrel 10 by water injection hole 13, and water injection hole 13 is tapped hole, is connected with barrel 10 to facilitate pressuring pump 14.Exhaust port 12 is tapped hole, and plug 15 is provided with gasket seal, to be seal-installed in exhaust port 12.Wherein, pressuring pump 14 can be manual pressuring pump or automatic pressuring pump.
As shown in Figure 2, introduce the utility model below for verifying the using method of the instrument of water pump seamless, the first step, pressuring pump 14 and barrel 10 are disconnected, plug 15 is unloaded from exhaust port 12, flange 11 is connected with the flanged surface 16 of water pump 17, so that barrel 10 is connected with water pump 17, and make water injection hole 13 and exhaust port 12 be in position the highest on the sidewall of barrel 10, wherein, gasket seal on the end face of flange 11 can make flange 11 and flanged surface 16 be tightly connected, and the flanged surface 16 of water pump 17 also can be avoided to be worn.Second step, injects water from water injection hole 13 to barrel 10, and the water injecting barrel 10 also can flow into water pump 17, and in the process to water filling in barrel 10, the gas in barrel 10 is discharged from exhaust port 12; Water is injected until the water of barrel 10 overflows from water injection hole 13 and exhaust port 12 simultaneously in barrel 10, because water injection hole 13 and exhaust port 12 are in position the highest on the sidewall of barrel 10, and water injection hole 13 and exhaust port 12 are positioned at on the straight line of the axis being parallel of barrel 10, so the water when water overflows from water injection hole 13 and exhaust port 12 simultaneously barrel 10 is substantially saturated.3rd step, plug 15 is installed in exhaust port 12, pressuring pump 14 is connected with barrel 10 by water injection hole 13, pressuring pump 14 is used slowly to suppress in barrel 10, open the Decompression valves of pressuring pump 14 in the process to be discharged by the residual air in barrel 10, repeatedly several times until the residual air in barrel 10 is all discharged, then pressurize a period of time, in pressure maintaining period, check that water pump is with or without leakage point, check that there is No leakage at mechanical sealing parts and the O RunddichtringO place of water pump, whether good to verify the sealing of water pump.Wherein, water injection hole 13 both for injecting water in barrel 10, was also suppressed in barrel 10 for pressuring pump 14, achieved a hole multiplex, simplified structure of the present utility model.
Instrument of the present utility model is also applicable to the sealing verifying various civil water pump.
