Description

Technical Field

[0001] The utility model relates to the technical field of pumps, in particular to an enhanced detachable pump cover structure. Background Art

[0002] As a centrifugal pump, the single-stage double-suction pump has a larger flow rate and better suction performance than the single-suction pump, and a higher head than the mixed-flow pump. The long-term use of the pump often requires the use of a detachable pump cover structure to facilitate users to perform quick maintenance.

[0003] Existing technologies include a utility model with a publication number of CN207018254U, which discloses a double-shell single-stage double-suction pump, including a pump body, a pump shaft, an impeller, a left pump cover, a right pump cover, a shaft sleeve, a left flow piece, a right flow piece, an inlet liner and an outlet liner; the inlet liner, the left flow piece, the right flow piece and the outlet liner constitute an inner shell, and the left pump cover, the pump body and the right pump cover constitute an outer shell; the pump shaft is supported by a single-side bearing, the outlet liner and the left flow piece are detachably connected to the left pump cover, and the right flow piece and the mechanical seal component are detachably connected to the right pump cover. However, for the single-layer shell structure usually used for single-stage double-suction pumps, it is necessary to improve the overall material performance, which is relatively costly, or to replace the flow components regularly, which increases the cost of disassembling, maintaining and replacing the flow components. In addition, single-stage double-suction pumps usually use two-end supports, corresponding to API type BB1 ​​axial split or BB2 radial split. However, the two-end support structure means that there are two sealing points for dynamic seals, and the mechanical seal auxiliary system is relatively complex and has low reliability.

[0004] At present, when most pump cover structures are used, the user installs the equipment where water needs to be pumped, then connects the water pipe to the water inlet pipe, places the other end of the water pipe in the water, then connects the fan blade to the motor, and starts the equipment to pump water. However, when the equipment is in use, the cover plate is generally firmly connected with bolts. The use of bolts requires tools to operate. Frequent use of bolts can easily cause thread slippage, causing the cover plate to detach from the surface of the outer casing. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an enhanced detachable pump cover structure, including a shell and a connecting device, the side of the shell is fixedly connected to a water outlet pipe, the surface of the shell is provided with a cover plate, the surface of the cover plate is fixedly connected to a water inlet pipe, the inside of the shell is provided with fan blades, the connecting device is provided on the side of the shell, the connecting device includes a first connecting block and a second connecting block, the first connecting block is fixedly connected to the side of the shell, the second connecting block is fixedly connected to the side of the cover plate, and the surface of the shell is fixedly connected to a limiting rod.

[0007] Preferably, the limiting rod is clamped with the inner wall of the cover plate, and a protrusion is fixedly connected to the surface of the first connecting block. By setting the limiting rod, the cover plate can be limited, which reduces the difficulty of the cover plate to be tightly combined with the surface of the shell when the device is installing the cover plate.

[0012] Preferably, a spring is fixedly connected to the side of the slider, and one end of the spring away from the slider is fixedly connected to the inner wall of the slide groove. The spring is provided to facilitate applying elastic force to the slider.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when using the device, the user installs the device at the place where water needs to be pumped, then connects the water pipe with the water inlet pipe, places the other end of the water pipe in the water, then connects the fan blades with the motor, and starts the device to pump water. When the device needs to be used, the user combines the cover plate with the surface of the shell, then the limit rod is combined with the inner wall of the cover plate to limit the position, rotates the rotating plate to drive the rotating rod to engage with the surface of the block, then rotates the rotating plate to be parallel to the surface of the first connecting block, then the rotating rod moves the block downward, and then the second connecting block drives the cover plate to be tightly combined with the surface of the shell. By setting the connecting device, the cover plate is effectively connected to the surface of the shell, which plays a role in stabilizing the cover plate, reducing the use of the device. The cover plate is generally firmly connected with bolts, and the use of bolts requires tools to operate.

[0015] 2. In the utility model, by setting a limiting device, when the device needs to be used, the user pulls the handle, and the handle moves to drive the slider to move. When the slider moves, it drives the limiting rod to move away from the inner wall of the limiting groove. The movement of the slider drives the spring to displace and deform to generate elastic force. When the limiting rod is separated from the limiting groove, the rotating plate loses its restraint. By setting a limiting device, the rotating plate is effectively restricted, which plays a role in restricting the rotating plate, reduces the situation where the rotating plate is easily affected by external force and rotates due to long-term use of the device when the device is in use, and improves the practicality of the device.
