Principiul de lucru al pompei hidraulice a excavatorului

Excavatoarele sunt un tip comun de utilaje și echipamente de construcții utilizate pe scară largă în excavarea pământului, transportul, încărcarea și alte operațiuni de inginerie. Pompa hidraulică este una dintre componentele de bază ale excavatorului, responsabilă pentru furnizarea de energie hidraulică stabilă. Așadar, cum funcționează pompa hidraulică a excavatorului? Acum să înțelegem în detaliu principiul de funcționare al pompei hidraulice pentru excavator.

Pompa hidraulică a excavatorului este formată în principal din corpul pompei hidraulice, arborele de transmisie, cuplajul și sistemul de control al pompei. Principiul său de funcționare este de a converti energia mecanică în energie hidraulică și de a o transmite altor actuatori hidraulici prin intermediul sistemului hidraulic pentru a realiza acțiunea excavatorului.

pompă hidraulică pentru excavator

The hydraulic pump body is the core component of the excavator hydraulic pump, usually using a gear pump or a plunger pump.There are a pair of gears or plungers that mesh with each other inside the hydraulic pump body, forming a certain volume inside the pump body. When the transmission shaft of the hydraulic pump rotates, the gear or plunger rotates accordingly, thereby changing the volume of the pump chamber. When the volume of the pump chamber increases, the pressure inside the pump decreases, and hydraulic oil enters the pump chamber through the suction port; When the volume of the pump chamber decreases, the pressure inside the pump increases, and hydraulic oil flows out of the pump chamber through the pressure port. Through this working principle, the hydraulic pump can continuously suck in and discharge hydraulic oil, forming stable hydraulic energy.

The hydraulic pump needs to be linked with other systems during operation, which requires the action of the transmission shaft and coupling. The transmission shaft transfers the power of the engine to the hydraulic pump, causing it to rotate; The coupling connects the hydraulic pump to the transmission shaft to ensure their synchronous operation. The control system of the hydraulic pump is responsible for controlling the start, stop, and working pressure parameters of the hydraulic pump. When the excavator needs to work, the control system will send a signal to the hydraulic pump to start and provide the corresponding working pressure. When the excavator does not need to work, the control system will stop the operation of the hydraulic pump to save energy. In general, the working principle of excavator hydraulic pump is to convert mechanical energy into hydraulic energy through the hydraulic pump body, and transmit it to other hydraulic actuators through the hydraulic system to achieve the action of the excavator. The operation of hydraulic pumps requires the coordination of the transmission shaft and coupling, and the control system controls its start, stop, and working pressure parameters. The working principle of the excavator hydraulic pump is simple, but it is the key to the normal operation of the excavator. Only by ensuring the normal operation of the hydraulic pump can the efficiency and performance of the excavator be improved. Therefore, in the operation and maintenance process of excavators, it is necessary to have a clear understanding of the working principle of hydraulic pumps and carry out timely maintenance and upkeep to ensure the normal operation of excavators.
