Pump inlet protection device and lubricating system with pump inlet protection device

Abstract

The invention provides a pump inlet protection device and a lubricating system with the pump inlet protection device. The pump inlet protection device is characterized in that the pump inlet protection device comprises a box body, a box body oil inlet and a box body oil outlet are formed in the box body, the box body oil inlet is provided with a first valve, and the box body oil outlet is provided with a second valve; a heating device is arranged on the side of the first valve in the box body, and a filtering device is arranged on the side of the second valve; and the positions, corresponding to the box body oil inlet and the box body oil outlet, of the outer wall of the box body are provided with connector structures, and the connector structures are used for enabling the pump inlet protection device to be detachably connected into a pump opening of the lubricating system. According to the pump inlet protection device and the lubricating system with the pump inlet protection device, impurities in fluid can be removed, and the meshing face of a pump is protected; and proper oil temperature conditions are provided, and the starting time is shortened.

Description

technical field [0001] The invention relates to the technical field of lubricating equipment, in particular to a pump inlet protection device and a lubrication system with the pump inlet protection device. Background technique [0002] The lubrication system is widely used, especially the lubrication system plays a very important role in the lubrication of transmission equipment in various working conditions. The transmission equipment has a large and heavy workload, and it basically works in the field, docks and mines, and the environment is complex If the lubricated bearings of the equipment are not lubricated well, it will affect the progress of the entire project and the implementation rhythm of factory production. Therefore, the reliability of the lubrication system is very important. [0003] Our country is vast and abundant, and the climate and geological conditions are different, resulting in changeable working conditions. The transmission equipment as general equipm...

Problems solved by technology

[0003] Our country is vast and abundant, and the climate and geological conditions are different, resulting in changeable working conditions. The transmission equipment as general equipment is also used in various working conditions, especially the transmission equipment at low temperature, often needs to wait for a long time because of the low oil temperature. Heating the lubricating oil in the box for a long time, or the lubrication system needs to be forced to start, because the oil temperature is low, resulting in a very large resistance of the system, a very high pressure, and a flow rate that cannot meet the system requirements. With a big impact, the entire system is alarming, causing the host to fail to start, giving the impression that the equipment is malfunctioning

[0004] In addition, the lubrication system of the existing transmission system does not have a pump inlet protection device, and the mechanical wear in the transmission box produces a large amount of iron filings and impurities, which are directly transported into the cavity of the gear pump or screw pump through the pipeline , These impurities are in direct contact with the gear pair or screw pair, and it is easy to scratch the precision meshing surface, resulting in an increase in the gap and a change in the flow rate. The impact on these quantitative pumps is fatal, and even large particles will be directly stuck in the The meshing surface will cause the motor of the transmission to be overloaded and burnt, or even cause the shaft to break, and the entire pump device will be damaged and the loss will be huge.
