Description

Technical Field

[0001] The utility model relates to the technical field of water pump installation, and particularly relates to an improved vertical split pump installation structure. Background Art

[0002] At present, in the existing vertical split double-suction pump, after installation, when the lower bearing, mechanical seal or other vulnerable parts are damaged, the entire rotor assembly can only be taken out of the pump body for maintenance; in addition, when the mechanical seal at the lower end of the conventional pump body is damaged and leaks water, the medium will directly overflow to the lower bearing, which has a great impact on the operation of the water pump; in addition, after long-term operation, the bearing in the bearing body lacks oil, and it is time-consuming and laborious to disassemble for adding grease. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above deficiencies and provide an improved vertical split pump installation structure, which solves the problems of difficult vertical installation of the split pump, difficult maintenance after installation, and difficult drainage of water leakage from the lower mechanical seal and oil leakage from the bearing.

[0004] To achieve the above purpose, an improved vertical split pump installation structure is designed, which includes a vertical split pump body 03. The vertical split pump body 03 is installed on a U-shaped base 01 at the bottom. The U-shaped base 01 has an inverted U-shaped structure. A back bracket 02 is fixed to the back of the vertical split pump body 03. The back bracket 02 is fixedly installed on the U-shaped base 01. A lower bearing body 05 is arranged at the lower part of the vertical split pump body 03. A water receiving tray 04 is installed at the upper end of the lower bearing body 05. A drainage hole 0402 is opened on the side of the water receiving tray 04. An oil filling hole 0401 is opened on the other side of the water receiving tray 04. A lower bearing gland 06 is installed at the lower end of the lower bearing body 05. An oil drain hole 0601 is opened on one side of the lower bearing gland 06.

[0005] Further, the longitudinal section of the back bracket 02 is triangular. The side of the back bracket 02 is fixedly connected to the vertical split pump body 03 by bolts. The bottom of the back bracket 02 is fixedly connected to the bottom plate of the U-shaped base 01 by bolts, thus ensuring the stability of the operation of the vertical split pump body to a certain extent.

[0006] Further, the longitudinal section of the back bracket 02 is a right triangle. The back surface and the vertical surface of the back bracket 02 are both fixedly installed on the U-shaped base 01, thereby further increasing its firmness.

[0007] Further, the support feet on the front and rear sides of the U-shaped base 01 are both L-shaped structures, and the support feet on the front and rear sides are both bent outward, further increasing the space and facilitating maintenance and replacement.

[0008] Further, the water receiving tray 04 is designed as a concave structure. The water receiving tray 04 is an integral structure composed of an upper bearing gland and a residual water tank. The upper bearing gland is press-fitted on the lower bearing body 05, so that it is convenient to add oil and drain oil when the bearing lacks oil.

[0009] Further, the bottom surface of the water receiving tray 04 is provided with protrusions, and is connected with the inner side of the top of the lower bearing body 05 through the protrusions. A skeleton oil seal is provided in the middle of the water receiving tray 04, and the skeleton oil seal is used to prevent dust from entering the lower bearing body 05.

[0010] Further, the top surface of the lower bearing gland 06 is provided with a second protrusion, and is connected with the inner side of the bottom of the lower bearing body 05 through the second protrusion, thus facilitating the installation and positioning during assembly.

On the premise of meeting the installation of the pump body, the space is increased as much as possible, which facilitates maintenance and replacement.

[0013] (2) The upper end of the lower bearing body of the utility model is designed with a water receiving tray. When the mechanical seal leaks, the water directly flows out through the drain hole and will not enter the bearing body. There is a special external oil filling hole for bearing oil filling and an oil drain hole for oil drainage, which facilitates maintenance and repair.

[0014] (3) There are two skeleton oil seals in the middle of the water receiving tray of the utility model, so as to effectively prevent dust from entering the lower bearing body.

[0024] The water receiving tray 04 is designed as a concave structure, the water receiving tray 04 is an integral structure composed of an upper bearing gland and a residual water tank, the upper bearing gland is pressed on the lower bearing body 05, so as to facilitate oil filling and oil leakage when the bearing is short of oil; a protrusion is arranged on the bottom surface of the water receiving tray 04, and the protrusion is in fit connection with the inner side of the top of the lower bearing body 05, a skeleton oil seal is arranged in the middle of the water receiving tray 04, and the skeleton oil seal is used to prevent dust from entering the lower bearing body 05; a second protrusion is arranged on the top surface of the lower bearing gland 06, and the second protrusion is in fit connection with the inner side of the bottom of the lower bearing body 05, thereby facilitating the installation and positioning during assembly.

[0025] When designing the open pump base in the present utility model, the height is raised and it is designed as a U-shaped base according to the U-shaped design. When designing the bottom plate of the U-shaped base, on the premise of meeting the installation of the pump body, the space is increased as much as possible. After the water pump is installed, it not only ensures the safety and reliability of the installation with the ground, but also increases the maintenance space. When maintenance is required, the on-site personnel can directly disassemble the bearing at the lower end of the water pump foundation. The upper bearing gland and the residual water tank of the lower bearing body are integrally designed as a water receiving tray. The water receiving tray is closest to the lower end mechanical seal, and the back of the water receiving tray is designed as a concave structure, and a water leakage hole is opened on the side to form a water diversion tray structure, which leads to the drainage ditch; when the lower end mechanical seal fails and leaks water, the residual water will flow to the water diversion tray and then be discharged through the water diversion pipe.

[0026] The structure of the vertical split-case pump mainly includes a back support, a U-shaped base, a water receiving tray, a bearing body, an oil filling cover plate, an oil leakage cover plate, etc.; the mechanical seal at the lower end of the vertical split-case pump is prone to water leakage. A water storage device is cast on the back of the bearing gland and a drain port is left; the lower bearing body of the vertical split-case pump is designed as a split structure, which is beneficial for refueling and oil drainage; due to the complexity of the pump body structure of the large split-case pump, a back support is designed on the back to fix its back and vertical surfaces on the base, increasing its firmness. When designing the base, it is designed as a U-shaped structure, so as to increase the height from the ground and facilitate the maintenance personnel to repair the lower bearing and mechanical seal.

[0027] In the new vertical split-case pump structure described in the present utility model, the split-case pump body is installed on the bottom U-shaped base. In order to ensure its firm fixation, a triangular back support is reinforced on the back of the pump body. The side of the back support is fixed to the split-case pump body by bolts, and the bottom is fixed to the bottom plate of the U-shaped base by bolts, thus ensuring the stability of the operation of the split-case pump body to a certain extent. The lower bearing body is designed as a split structure. There is a drain hole on the water receiving tray, and a corresponding oil filling hole, which is convenient for refueling from the oil filling hole when the bearing lacks oil; an oil drain hole is designed on the lower bearing gland. After the rotor rotates, the bearing wears, and the oil is discharged from the oil drain hole; the water receiving tray is an integral casting structure, which not only ensures the stability of the material, but also combines water collection and oil filling on one casting, reducing the material cost and meeting the use requirements.
