Protection mechanism beneficial to stable operation of pressure pump

The protection mechanism facilitating stable operation of the pressure pump comprises an installation base, the pressure pump is fixedly installed on the installation base, half cover bodies capable of being synchronously adjusted to be opened and closed are arranged at the positions, corresponding to the two sides of the pressure pump, of the installation base, and the half cover bodies are matched with each other to form an outer protection cover used for wrapping the pressure pump. The two half cover bodies are arranged on the outer side of the pressure pump, the two half cover bodies are spliced to form the outer protective cover and wrap the pressure pump, the outer protective cover can effectively protect the pressure pump, dust and other impurities are prevented from being attached to the surface of the pump body to cause corrosion and aging, the outer protective cover can play a sound receiving role, and therefore noise is reduced, and the service life of the pressure pump is prolonged.
