2CY, KCB gear pump failure analysis and troubleshooting: I. Less oil or less oil Production reasons: 1, inhalation height exceeds the rated value 2, suction pipe leakage 3, the rotation direction is not 4, the suction pipe is blocked or the valve is closed 5, the safety valve stuck or injury 6, the liquid temperature is low and the viscosity increases Exclusion: 1, improve the level of inhalation 2, check the joints, the best sealing material seal 3, then pump the direction shown in the correct 4 , Check the pipeline is clogged, the valve is open 5, open the safety valve cleaning and fine sand abrasive grinding hole, the use of anastomosis 6, preheat the liquid or reduce the pressure to exclude two. Seal oil leakage Production reasons: 1, seal wear 2 , Packing seal packing wear 3, mechanical seal wear or scratches and other defects 4, mechanical seal spring failure troubleshooting: 1, replace the seal 2, adjust the packing gland tightness, replacement or replacement filler 3, replace or re-grinding 4 , Replacement 3. Noise or vibration Large production reasons: 1, suction and filter plugging 2, the suction tube into the liquid level Shallow 3, the air into the pipe 4, the exhaust pipe resistance is too large 5, the gear bearing or side plate serious wear 6, the viscosity of inhaled liquid is too large 7, the inhalation height exceeds the rated value Exclusion method: 1, to eliminate gear pump dirt on the filter 2, the suction tube growth below the surface of the liquid level 3, check the connections to seal it 4, check the discharge pipe and the valve is blocked 5, remove the cleaning and repair defects or replacement 6, heating viscosity or treatment 7, Reduce the suction height and shorten the suction pipe length
High Speed Door
High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
