Skewness, can all there are different regions to be threatened by arid every year, cause very big economic loss.Come for agricultural production
Say, water is too busy to get away.For typically can all be drawn water with the difficult area of water in order to irrigate using suction pump, to ensure to make
The normal growth of thing.
Mainly it is attached between traditional suction pump and pipeline by ring flange, but with the passage of usage time, method
Different degrees of abrasion unavoidably occurs due to reasons such as dismountings in junction between blue disk；With the expansion of wearing part
Greatly, it may finally cause occur the phenomenon of leak between the pump housing and pipeline.Some producers, can be in flange in order to avoid there is leak
Sealing ring is set between disk, but in general sealing ring be it is simple be clipped between two ring flanges, cure the symptoms, not the disease, it is final also
It is to be difficult to solve the problems, such as leak.And after leak occurs, on the one hand, the operating efficiency of suction pump can be caused to reduce；On the other hand,
Because suction pump is necessary to ensure that hydraulically full in the pump housing at work, and leak may cause the fluid loss in the pump housing, so as to
So that the pump housing is at work, inner body is damaged due to lacking the reason such as hydrodynamic lubrication and radiating.Obviously traditional suction pump
The Shortcomings in terms of pipeline connection.
The high-accuracy suction pump that the problem of existing for above-mentioned prior art designs a kind of preventing water leakage is the utility model
The purpose of research.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model is that providing a kind of the high-accuracy of preventing water leakage draws water
Pump, it can effectively solve the problem that the above-mentioned problems of the prior art.
The technical solution of the utility model is：
A kind of high-accuracy suction pump of preventing water leakage, includes base and the pump housing, and the pump body is provided with impeller, the leaf

The mouth of a river and water inlet are respectively connected with corresponding assembling pipe joint；The assembling pipe joint includes be fixed on the pump housing
One flange and the second flange being fixed in corresponding pipeline, the first flange are set in the contact surface annular with second flange
There is a groove, the cross section of the groove is arranged to skewed, and trapezoidal back-off is provided with the bosom of the groove
Groove；The second flange is provided with the mounting groove of annular in the position of respective slot, is provided with the mounting groove and is arrived for device
The rubber seal of groove, the cross section of the rubber seal are consistent with the cross section of groove.
The impeller is connected with rotating shaft, and the other end that the rotating shaft is not attached to impeller is connected to driving electricity by shaft coupling
The output shaft of machine.
The first flange locks second flange by corresponding screw bolt and nut.
The advantages of the utility model：
The utility model includes the pump housing and motor, and when in use, the water inlet and delivery port of the pump housing pass through respectively
Corresponding assembling pipe joint is connected to corresponding pipeline；Assembling pipe joint includes first flange and second flange, the first method
Groove and the rubber seal for device to groove are respectively arranged with blue and second flange；Because groove cross section is set
To be skewed, therefore rubber seal installation is easy, and the back-off groove that fit bosom is set, and can effectively ensure rubber
Glue sealing ring is clamped in groove, so as to effectively lift the sealing effectiveness between first flange and second flange, so as to prevent
Leak and the service life and operating efficiency for improving equipment.The utility model is not only simple in structure, and can strengthen pipeline
Sealing between the pump housing, so as to improve the service life of equipment and operating efficiency.
