QYB50-60L pneumatic oil pump
QYB40-120L pneumatic oil pump is a large strain and huge displacement oil pump that converts air force into hydraulic energy. It is managed by pneumatic elements and is mostly used in programs that use hydraulic oil as the medium. When the electrical pump fails, the energy is lower off or the power is not authorized, the oil pump can be started out, and the hydraulic system can be quickly loaded with oil. It is an auxiliary pump on the BOP manage device.

three. Construction and functioning principle
QYB40-120L pneumatic oil pump is largely composed of the adhering to areas:
Pump head, valve main connecting rod, trachea assembly, valve main, valve main sleeve, pump head seat, valve core 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, and many others.
Compressed air enters the higher cavity of the cylinder from the air inlet of the pump head by way of the valve core sleeve, the reduced air inlet on the valve core, the two air inlets at the reduced conclude of the pump head, and the air inlet of the pump head seat, pushing the piston down. At the identical time, the air in the lower chamber of the cylinder enters the exhaust chamber of the pump head by means 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 metal ball B1 moves up, and the steel ball B2 closes the oil suction port. The force oil enters the higher cavity of the plunger cylinder (component) and is pressed out by means of the oil discharge port of the physique. When the piston moves down to the piston rod nut and contacts the spool rod retainer ring, the piston continues to move down. The piston drives the spool down by a pitch via the spool rod and the spool connecting rod. At this time, the upper component of the spool moves downwards. The air port is closed, and the higher air inlet is related with the upper air inlet cavity of the pump head to realize the reversal.
at this time. Compressed air passes by way of the valve core sleeve from the air inlet of the pump head. The higher air inlet on the valve main, the air pipe and the air inlet of the foundation enter the decrease cavity of the cylinder, pushing the piston upward, and the air in the higher cavity of the cylinder passes by way of the pump head seat. , The exhaust cavity of the pump head is discharged from the exhaust hole. At the exact same time, the piston drives the plunger rod assembly upward by means of the piston rod assembly. At this time, the metal ball B2 moves upward, and the hydraulic oil enters the reduced cavity of the cylinder from the oil suction port, and the metal ball B1 is closed. The strain oil in the upper cavity of the plunger cylinder assembly is pressed out from the oil discharge port of the human body. When the piston moves up to the spring, it touches the base stop area of the inner hole of the piston rod assembly and proceeds to shift up. At this time, the piston drives the valve core to go up a pitch by way of the valve core rod and the valve main connecting rod. At this time, the decrease part of the valve main The air inlet is in interaction with the reduced air inlet cavity of the pump head, and compressed air enters the higher cavity of the cylinder to recognize the direction alter. In this way, the path of the air movement into the cylinder is reciprocated, and the piston and the piston rod assembly repeatedly reciprocate up and down. At the exact same time, the plunger rod assembly is also pushed to reciprocate up and down to comprehend the oil suction and discharge method of the pump.
one. Characteristics and recommendations
The doing work qualities of the pneumatic oil pump are: intermittent oil suction, continuous oil discharge, stable begin, and load begin.
The location ratio of the cylinder of the pneumatic oil pump to the annular finish experience of the cylinder cavity is fifty:one. For that reason, the theoretical ratio of the consumption force to the discharge stress is 1:fifty. When the air supply pressure is .53~.8Mpa (75~115psi), the theoretical highest output oil pressure can reach 26.5~40Mpa (3850~5800psi).
The oil discharge and air use of the pneumatic oil pump are both unstable, but alter with the load pressure. When the load strain is reduced, the pump strokes boost, and the oil discharge and air usage enhance when the load stress is high, the pump strokes lower, and the oil discharge and air consumption lessen.
