Description

TECHNICAL FIELD

[0001] The utility model relates to centrifugal water pump technical field more specifically, it relates to a water pump convenient to maintain. BACKGROUND

[0002] Centrifugal water pump mainly relies on the centrifugal force produced by impeller rotation to work. When the impeller rotates at high speed in the pump shell, the liquid at the center of the impeller is thrown to the edge of the impeller under the action of centrifugal force to realize water supply, but the existing water pump will produce corrosion after long time use, and it is difficult to maintain.

[0003] At present, the maintenance of water pump adopts manual repair mode, however, the water pump equipment usually has the problems of running, leaking and dripping. It is worth noting that the occurrence position of such running, leaking and dripping phenomenon is mostly concentrated in the connection between the motor and the pump body. Once the corrosion develops to a certain extent, the adhesion phenomenon will occur at the connection between the motor and the pump body. Such adhesion is not a simple surface adhesion, which will greatly hinder the smooth relative movement between the motor and the pump body, and further affect the normal operation of the whole water pump equipment, which greatly affects the efficiency of repair and increases the work difficulty and work time of maintenance personnel, which is not conducive to the efficient operation of the factory.

[0004] Therefore, the utility model provides a water pump convenient to maintain, which solves the problem of corrosion and adhesion of the motor and the pump body caused by running, leaking and dripping. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a water pump convenient to maintain, which solves the problem of corrosion and adhesion of the motor and the pump body caused by running, leaking and dripping.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A water pump convenient to maintain, comprising a motor assembly, a shell assembly and an impeller assembly, the motor assembly is suitable for providing driving; the motor assembly comprises a motor shell, a plurality of motor pry blocks are arranged around the bottom end of the motor shell; the shell assembly is arranged at the bottom end of the motor assembly, and the shell assembly is suitable for providing water flow guidance; a plurality of shell pry blocks are arranged around the side of the water pump shell close to the motor shell, and a knife slot is formed in the side of the shell pry block close to the motor pry block; the impeller assembly is arranged inside the shell assembly, and the impeller assembly is suitable for providing flow ability for water.

[0008] The utility model is further provided as follows: a plurality of motor pry blocks and shell pry blocks are shape-adapted, and the knife slot is suitable for inserting a tool to separate the motor assembly and the shell assembly.

[0009] By adopting the above technical scheme, after long-term use, the water pump will have problems such as leakage, which will cause rust on the water pump shell. Usually, the rust occurs between the motor and the pump body, and the rust will cause the two parts to be adhered. This adhesion makes it difficult for workers to separate the two parts. At this time, tools such as a screwdriver, a crowbar, etc. can be used by inserting the tool into the slot and prying up to loosen the two parts. The motor and the pump body can be quickly disassembled and separated, and the maintenance efficiency is improved.

[0010] The utility model further sets up: the impeller assembly includes motor output rod, motor output rod top is provided with water pump impeller, water pump impeller top is provided with screw slot.

[0011] The utility model further sets up: the screw slot is set up as screw thread shape structure, and the screw thread direction of the screw slot is opposite to the rotating direction of the water pump impeller.

[0012] The utility model further sets up: the screw slot top is provided with fixed screw, and the fixed screw is matched with the shape of the screw slot.

[0013] The utility model further sets up: the motor output rod is provided with a limiting block on the side close to the water pump impeller, the limiting block is set as a cylindrical structure, and the diameter of the limiting block is greater than that of the motor output rod.

[0014] By adopting the above technical scheme, the water pump needs to be maintained by disassembling the impeller and the sealing element. The impeller is usually separated by a puller. The puller is relatively complex to use, which is not conducive to quick maintenance and repair. Therefore, the motor output rod is connected with the motor output end, the water pump impeller is inserted into the top end of the motor output rod, and the spline exists between the water pump impeller and the motor output rod. The driving force of the motor can be better transmitted to the water pump impeller, so that the water pump impeller can rotate more stably. The fixed screw and the limiting block cooperate to completely fix the position of the water pump impeller, prevent it from moving up and down, and cause damage to the water pump impeller. The screw slot with the screw thread direction opposite to the rotating direction of the water pump impeller can provide a force in the opposite direction when the water pump impeller rotates, so that the fixed screw can press the water pump impeller more tightly to prevent it from loosening. The installation and disassembly speed of the water pump impeller is improved, and the possibility of damage to the water pump impeller is reduced.

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

[0016] 1、Water pump after long-term use, will produce run, leakage problem, this will produce rust on the water pump shell, usually these rust will occur between the motor and the pump body, the rust produced will make the two parts adhere, the adhesion will make it difficult for workers to separate the two parts, at this time, can be used by using tools, for example, a screwdriver, crowbar, etc., by inserting the tool into the slot, up and down pry the two parts loose, can be faster disassembly and separation of the motor and the pump body, improve the maintenance efficiency.

[0017] 2、Water pump maintenance needs to be removed impeller and sealing, impeller usually uses a puller to achieve separation, puller is more complex, is not conducive to quick maintenance and repair, therefore, through the motor output rod and motor output end connection, water pump impeller plug-in at the top of the motor output rod, water pump impeller and motor output rod between the spline, can better transmit the driving force of the motor to the water pump impeller, so that the water pump impeller can rotate more stably, fixed screw and limit block can completely fix the position of the water pump impeller, prevent its up and down movement, cause the water pump impeller damage, the screw groove with the opposite direction of the water pump impeller rotation direction, when the water pump impeller rotation can provide the force in the opposite direction, so that the fixed screw on the water pump impeller is more tight, prevent its loose. Improve the installation and disassembly speed of the water pump impeller, and reduce the possibility of the water pump impeller being knocked. BRIEF DESCRIPTION OF DRAWINGS
