QYB40-165L pneumatic oil pump
1 Overview
QYB40-120L pneumatic oil pump is a substantial stress and massive displacement oil pump that converts air force into hydraulic electrical power. It is managed by pneumatic factors and is mainly used in techniques that use hydraulic oil as the medium. When the electric pump fails, the electricity is reduce off or the energy is not authorized, the oil pump can be began, and the hydraulic method can be quickly stuffed with oil. It is an auxiliary pump on the BOP manage gadget.

three. Structure and functioning principle
QYB40-120L pneumatic oil pump is mostly composed of the adhering to parts:
Pump head, valve main connecting rod, trachea assembly, valve core, valve core sleeve, pump head seat, valve main rod, piston rod nut, piston, piston rod assembly, cylinder, valve core rod retaining ring, spring, foundation, column Plug rod assembly, physique, plunger rod sealing assembly, plunger cylinder sealing assembly, plunger cylinder assembly, steel balls B1, B2, polyurethane sealing ring B3, etc.
Compressed air enters the higher cavity of the cylinder from the air inlet of the pump head through the valve main sleeve, the reduce air inlet on the valve core, the two air inlets at the lower stop of the pump head, and the air inlet of the pump head seat, pushing the piston down. At the same time, the air in the lower chamber of the cylinder enters the exhaust chamber of the pump head by way of the air consumption gap and air pipe assembly of the foundation and is discharged from the exhaust port. The piston drives the plunger rod assembly down via the piston rod assembly. At this time, the steel ball B1 moves up, and the metal ball B2 closes the oil suction port. The stress oil enters the higher cavity of the plunger cylinder (ingredient) and is pressed out by means of the oil discharge port of the human body. When the piston moves down to the piston rod nut and contacts the spool rod retainer ring, the piston proceeds to shift down. The piston drives the spool down by a pitch by means of the spool rod and the spool connecting rod. At this time, the higher part of the spool moves downwards. The air port is shut, and the upper air inlet is linked with the higher air inlet cavity of the pump head to realize the reversal.
at this time. Compressed air passes through the valve core sleeve from the air inlet of the pump head. The higher air inlet on the valve core, the air pipe and the air inlet of the base enter the lower cavity of the cylinder, pushing the piston upward, and the air in the upper cavity of the cylinder passes via the pump head seat. , The exhaust cavity of the pump head is discharged from the exhaust gap. At the very same time, the piston drives the plunger rod assembly upward via the piston rod assembly. At this time, the steel ball B2 moves upward, and the hydraulic oil enters the lower cavity of the cylinder from the oil suction port, and the metal ball B1 is closed. The stress oil in the higher cavity of the plunger cylinder assembly is pressed out from the oil discharge port of the physique. When the piston moves up to the spring, it touches the base end area of the internal hole of the piston rod assembly and continues to shift up. At this time, the piston drives the valve main to shift up a pitch by means of the valve core rod and the valve main connecting rod. At this time, the reduced portion of the valve main The air inlet is in interaction with the decrease air inlet cavity of the pump head, and compressed air enters the higher cavity of the cylinder to understand the course adjust. In this way, the course of the air stream into the cylinder is reciprocated, and the piston and the piston rod assembly continually reciprocate up and down. At the same time, the plunger rod assembly is also driven to reciprocate up and down to recognize the oil suction and discharge method of the pump.
1. Functions and directions
The doing work qualities of the pneumatic oil pump are: intermittent oil suction, steady oil discharge, stable commence, and load start off.
The spot ratio of the cylinder of the pneumatic oil pump to the annular end encounter of the cylinder cavity is fifty:one. Consequently, the theoretical ratio of the ingestion stress to the discharge strain is one:fifty. When the air source strain is .fifty three~.8Mpa (seventy five~115psi), the theoretical optimum output oil stress can get to 26.five~40Mpa (3850~5800psi).
The oil discharge and air use of the pneumatic oil pump are each unstable, but alter with the load pressure. When the load pressure is reduced, the pump strokes improve, and the oil discharge and air use boost when the load pressure is large, the pump strokes lower, and the oil discharge and air consumption reduce.
