Precautions for selecting and using oil well pumps

Purpose: To determine whether the purpose of purchasing an oil well pump is for household or commercial use. Different applications have different requirements for the power, flow rate, and durability of oil pumps.

Working principle of oil well pump

Under the drive of the pumping unit, the oil pump changes the pressure state inside the pump barrel through the reciprocating motion of the plunger, combined with the alternating opening and closing of two one-way valves (suction valve and discharge valve), to achieve the suction and discharge of liquid.

Application scenarios of hand cranked jacks

Engineering field: widely used in factories, warehouses, docks, railways, and construction projects, especially suitable for mechanical equipment installation, locomotive maintenance, and other operations.

The working principle of a diesel engine

Intake Stroke: The piston moves downward, the intake valve opens, and fresh air is drawn into the cylinder. Compression Stroke: The piston moves upward, compressing the air to a high-temperature, high-pressure state (temperatures can reach 500–700°C, with pressures up to 3–5 MPa).
