Water-free operation cooling device and method for booster pump

Abstract

The invention discloses a water-free operation cooling device for a booster pump. The water-free operation cooling device comprises a water tank (5); the water tank (5) is connected with the upper end of a first hose (4) and the upper end of a third hose (6); the lower end of the first hose (4) is connected with the water inlet end of a water outlet valve (3); the water outlet end of the water outlet valve (3) is communicated with the water inlet end of a booster pump (2); the lower end of the third hose (6) is communicated with the water outlet end of a diaphragm pump (7); the water inlet end of the diaphragm pump (7) is communicated with the water outlet end of a water injection valve (8); the water inlet end of the water injection valve (8) is communicated with one end of a second hose (9); and the other end of the second hose (9) is communicated with the water outlet end of the booster pump (2). The invention further discloses a water-free operation cooling method for the booster pump. According to the water-free operation cooling device and method for the booster pump, the requirement for the spatial position is flexible; the occupied space is small; and the operation problem in a water-source-free state can be solved.

Description

technical field [0001] The invention relates to a water-free operation cooling device and method of a booster pump, belonging to the technical field of booster pump cooling and lubrication. Background technique [0002] The booster pump is strictly forbidden to run idling in the absence of water. Under normal working conditions, connect the water source, start the engine, and the booster pump will run without additional cooling and lubrication systems. When the booster pump engine is not used for a long time, routine start-up maintenance is required. When the engine starts, the booster pump works at the same time. At this time, the booster pump is not connected to the water source, and the booster pump is idling in an anhydrous state, which will generate a lot of heat and cause heat and wear of the mechanical seal. [0003] In the prior art, a clutch can be installed between the engine and the booster pump. When the engine needs to be started and maintained, the booster pum...

AI Technical Summary

Problems solved by technology

But due to the limited space between the arranged booster pump and the engine, it may not be possible to place the clutch

In addition, the installation of the clutch will cause an increase in cost

If the clutch is not installed, when starting and maintaining the engine, start and maintain the engine quickly, the booster pump has no water source connection, and the booster pump system has no cooling and lubrication. Although the startup time is short, excessive heat and wear will not be generated, but In the process of maintaining and running the engine, there is some damage to the booster pump, and the running and maintenance time is short
