Screw pump operation should pay attention to what problems

Rod pump must be in the direction of the established operation to produce a certain suction row.
Pump work, should pay attention to check the pressure, temperature and mechanical seal work. Shaft seal should allow a trace of leakage, such as leakage does not exceed 20-30 seconds / drop, then that normal. If the screw pump noise during work, which is often due to the oil temperature is too low, the viscosity of the oil is too high, the oil into the air, the coupling lost in the pump or excessive wear and other causes.

The flat sheets are processed using a dedicated high-precision fully automatic uncoiling, leveling and shearing production line to achieve high precision, low stress (six-fold precision leveling), full protection (online double-sided lamination), and traceability (online laser marking) of thin sheets )'s automated flow operation ensures high-quality full stress relief from coiled plate to flat plate and flatness of the plate before forming.


The press system using anti-compensation technology and the high-precision mold cooperate to ensure that the entire plane pressure of the pressing mold is consistent, so that the corrugation depth accuracy deviation is controlled at ±0.1-0.2mm, which is higher than the industry standard of ±0.25mm, ensuring that the plate After being assembled upside down, the corrugated contacts are in 100% complete contact, which greatly improves the plate's pressure-bearing capacity, alternating current resistance, and impact resistance.

Laser marking enables each plate to be permanently marked and retained for life, making it easy for users to trace and inquire.

Large plates adopt double-sided coating processing technology to achieve the ultimate forming accuracy of the plates. The maximum processing thinning amount is only 20% of the plate thickness, which is higher than the 23% specified by the industry standard; at the same time, the surface of the plates after forming is Scratches greatly extend the service life of the plate.

All holes in the plate are punched out at once after the overall one-time pressing, ensuring the assembly and positioning accuracy of the plate (including 4 corner holes, 2 plate positioning holes, 4 auxiliary positioning corners and peripheral pads card slot).
The only intelligent visual inspection system for plates in the industry can automatically identify all through-cracks and micro-cracks on plates, automatically detect corrugation depth deviations, and automatically detect all unqualified plates, ensuring zero defects in factory products.
