Abstract
The utility model relates to a novel mining vertical pump motor housing. The pressure gauge and the matching device thereof are arranged on the motor shell of the mining vertical pump, the pressure gauge can be disassembled during transportation, carrying and maintenance, the pressure gauge can be quickly installed during use, and the pressure gauge is protected and convenient to replace.
Description
Technical Field
The utility model relates to a mining vertical pump, it is the sand pump that contains solid abrasive particle in the transportable liquid, it is amphibious formula sand pump that can use on land and under water.
Background
The prior art comprises three inventions: the device comprises a mining vertical pump ZL200410078876.4, a mining vertical pump ZL200410078879.8 and a mining vertical pump ZL 200410078880.0.
The utility model discloses a mining vertical pump upgrading technology, neotype mining vertical pump motor housing.
Disclosure of Invention
The mining vertical pump is a sand pump, and requires a user to install a pressure gauge on a water outlet pipe, and the installation, debugging, use and maintenance are carried out, so that the operating state of the water pump is judged according to the pressure value during fault judgment, and the fault reason is found.
1. After the positive and negative rotation is judged, namely the gate valve is closed, the pump is opened in the positive rotation mode and the negative rotation mode, and the positive rotation mode is judged if the pressure gauge value is large.
2. The pressure gauge value is checked after the water pump normally operates, the pipeline loss (the pipeline loss of the sand-containing slurry can only be obtained through actual measurement) can be calculated by subtracting the drainage height difference from the value, the surplus of the pump head of the water pump can be judged, whether the water pump is reasonable in model selection or not can be judged, whether the water pump is used near the optimal efficiency point or not can be judged, and a basis is provided for energy-saving drainage.
3. During the operation of the water pump, the pressure value suddenly rises, which indicates that the water outlet pipe is blocked and needs to take corresponding measures.
4. When the water pump runs, the pressure value suddenly drops, which indicates that the water suction port or the water suction filter screen is blocked and needs to be cleaned in time.
5. During the operation of the water pump, the pressure value suddenly drops and swings greatly, which indicates that the water pump sucks air, and the water level is checked or the water suction pipe is checked.
6. After the valve is operated for a period of time, the pressure value (closing dead point pressure) after the gate valve is closed is greatly reduced, which indicates that the water pump is worn out of limit and a wearing part needs to be replaced.
Therefore, the sand pump is different from a clean water pump and a sewage pump, the pressure gauge is very important for the use of the mining vertical pump, but almost all users do not install the pressure gauge, no pressure gauge facility is arranged on a drainage system, and when silt is contained in water, the pressure gauge installed by the users is easy to damage and is difficult to replace.
The utility model aims at: the utility model provides a mining found pump sets up manometer and supporting device on mining found pump's motor housing, but detachable manometer during transportation, transport, maintenance, but quick installation manometer during the use, manometer protection facilities in addition, and it is convenient to change.
The utility model adopts the technical proposal that: the mining vertical pump comprises a pump body, a pump shaft, an impeller and a motor, wherein a motor shell is a double-layer shell, a drainage channel of the mining vertical pump is arranged in the middle of the motor shell, and the motor shell comprises a motor upper end cover, a motor shell and a motor lower end cover. And a screw hole for mounting a pressure gauge device is formed in the motor shell. And during transportation, transportation and maintenance, the screw hole is provided with a plug. The installation is debugged, is used and is maintained, can pull down the plug during failure diagnosis, installs the manometer device, and the manometer device includes manometer, table valve, outer silk, and outer silk mountable is on the screw of motor housing. And (4) closing the gauge valve to protect the pressure gauge at ordinary times, opening the gauge valve when reading the data of the pressure gauge, and closing the gauge valve after reading. The pressure gauge can be replaced when the gauge valve is closed.
Drawings
Fig. 1 is a longitudinal section schematic view of the mining vertical pump motor shell of the embodiment of the invention.
Detailed Description
The mining vertical pump of the present invention will be further described with reference to the accompanying drawings.
Fig. 1 is an embodiment of the utility model discloses a mining vertical pump motor casing.
In fig. 1, the mining vertical pump comprises a pump body 5, a pump shaft 3, an impeller 6 and a motor, wherein a motor shell is a double-layer shell, a drainage channel of the mining vertical pump is arranged in the middle of the motor shell, and the motor shell comprises a motor upper end cover 1, a motor shell 2 and a motor lower end cover 3. The motor shell is provided with a screw hole 10 for installing a pressure gauge device. When transporting, transporting and maintaining, the screw hole is provided with a plug 11. Installation and debugging, use and maintenance, can install the manometer device during failure diagnosis, and the manometer device includes manometer 7, table valve 8, outer silk 9, and outer silk 9 mountable is on motor housing's screw 10. At ordinary times, the gauge valve 8 is closed to protect the pressure gauge 7, the gauge valve 8 is opened when pressure gauge data is read, and the gauge valve 8 is closed after reading. The pressure gauge 7 can also be replaced when the gauge valve 8 is closed.
