The oil pumping unit crankshaft is used as the transmission structure for different oil pumps, circulating pumps, reflux pumps, column bottom pumps and other pump types.

Material
Crankshafts are one of the most crucial components to the oil pumping unit, where the appearance directly influences the pump's service life. It is vital to choose the right material for a crankshaft, as the crankshaft must be able to handle a heavy load and changing torque.

For this crankshaft, we generally choose to use alloy steel as the production material, for the following reasons.
a. Alloy steel has better tensile strength, yield strength and ductility than nodular cast iron and quality carbon.
b. Alloy steel also has an outstanding strength and impact resistance. Compared to quality carbon steel, it has a better physical, chemical and mechanical performance.

Features
1. We have a professional CNC crankshaft grinder and CNC cylindrical grinder, with the eccentric distance featuring an accuracy of 0.01mm and the cylinder accurate to 0.005mm.

2. Our crankshafts are known for their rigidity, strength and impact resistance.

3. Crankshaft materials include alloy, and a roughness of Ra0.02 after polishing, giving it an excellent wear resistance and lubricity.

4. Nazhen owns and operates numerous professional detection equipment sets, including a trilinear coordinates measuring instrument, contour graph and rough meter in order to carry out strict detection processes for the degree of parallelism of the crankshaft, torsion resistance of the crankshaft and coaxiality of the two crank throw. This ensures all crankshafts rotate smoothly and with no noise, vibrations or shaking, thus ensuring a long service life for the compressor.

NAZHEN specialize in designing and manufacturing high quality crankshafts, is a recognized precision crankshaft manufacturer and oil pumping unit crankshaft supplier. There are crankshafts like alloy steel crankshaft, carbon steel crankshaft, forged crankshaft, cast iron crankshaft for choose. As we use complete manufacturing and testing equipment, we are committed to providing high quality precision crankshafts and solutions, the oil pump crankshafts can be made based on customer required materials and drawings to meet client demands.
