Description

Technical Field

[0001] This utility model relates to the field of assembly technology for water pump castings, and more specifically, it relates to a water pump casting that is easy to assemble. Background Technology

[0002] The assembly of water pump castings mainly includes impeller assembly, pump casing assembly, and sealing device assembly. After the pump casing is assembled, a sealing test is required. This test involves filling the inside of the water pump casting with liquid, applying a certain static pressure, and observing whether there is any leakage.

[0003] Currently, the testing process mainly involves sealing the inlet and outlet openings of the water pump casting, connecting a water injection device, and slowly injecting water into the casting until the entire internal space is filled. This part of the operation is mainly done through flange connections. Operators need to install sealing plates at the inlet and outlet and tighten the bolts before testing can be carried out, which greatly reduces the efficiency of the testing. On the other hand, manual tightening of bolts cannot guarantee that the tightness of each bolt is consistent. If one side is not tightened, it may lead to water leakage, which also reduces the efficiency of the testing.

[0004] Therefore, a water pump casting that is easy to assemble is proposed to solve the problems of impeller assembly and pump casing sealing test assembly. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water pump casting that is easy to assemble, saves assembly time, improves testing efficiency, and improves work efficiency.

The water supply assembly includes an impeller with a connecting mechanism at its top and a fixing bolt at its bottom.

[0008] The present invention is further configured such that the chassis, the inlet connection plate, and the outlet connection plate are connected by pipes, and the multiple sets of quick-connect plates are adapted to provide snap-fit ​​connections for external pipes.

[0009] By adopting the technical scheme, when the water pump is tested, the internal sealing test needs to be performed, that is, the water pump casting is filled with liquid, then a certain static pressure is applied, and whether the casting leaks is observed. The basis is Pascal's law, that is, the pressure applied on the liquid is uniformly transmitted to each part of the casting. At this time, the water inlet connecting disc and the water outlet connecting disc of the water pump casting need to be externally connected with the water pipe or the plugging block, and the quick connecting piece is matched with the buckle on the externally connected water pipe or the plugging block, so that the test can be quickly assembled, time is saved, and the detection efficiency is improved.

[0012] The utility model further sets up: the connecting rod diameter is identical with the diameter of impeller inner wall, the solid wheel block outer wall diameter is greater than connecting rod setting.

[0013] The utility model further sets up: the connecting rod is close to the side of impeller and is equipped with fixed groove, and the fixed groove is shape adaptation with fixed bolt.

[0014] By adopting the technical scheme, the connecting rod is inserted into the inside of the impeller, the spline is arranged on the connecting rod, and the groove is arranged on the inner wall of the impeller, so that the slipping between the connecting rod and the impeller can be avoided, the depth of the connecting rod inserted into the impeller is limited by the solid wheel block, the impeller is prevented from sliding on the connecting rod and affecting the water supply efficiency of the water pump. The fixed groove provides the mounting environment for the fixed bolt, and the width of the end of the fixed bolt away from the screw thread is greater than the setting of the inner wall of the impeller, so that the position of the impeller is further limited, and the impeller is prevented from sliding downward. When the operator assembles, only needs to insert the solid wheel block into the impeller by aligning the position of the spline and the key groove with the end of the solid wheel block downward, and then the fixed bolt is tightened by using a wrench, so that the assembly is completed. The impeller is assembled by using the water supply assembly, so that the assembly is simple, fast and efficient, and the working efficiency is improved.

[0015] In summary, the present application has at least one of the following beneficial technical effects:
