Water pump troubleshooting tips

The pump does not turn at start-up. Cause: The packing is too tight or the impeller and the pump body are jammed by debris; the pump shaft, bearing and leakage ring are rusted; the pump shaft is severely bent. Remedy: Relax the packing and unclog the sink: disassemble the pump to remove debris or rust; correct the bent shaft or renew the pump shaft. After the start of the pump does not produce water? Reason: pump air or water pipe product gas; bottom valve is not closed, irrigation is not filled, vacuum pump packing is seriously leaking; gate valve or flap door is not strict. Remedy: Remove debris, replace the damaged rubber pad, change the direction of the valve; compact or replace the new packing, close the valve or shoot the door; increase the amount of irrigation, until the bleeder plug does not take the air; replacement Cracked pipe water; reduce the head and push the pump nozzle into the water for 0.5 meters. Insufficient flow rate Reason: The actual lift of the pump exceeds the allowable lift; the speed is not matched or the belt slips and the speed is low; the installation angle of the axial pump blade is too small; the suction range is too high; the bottom valve, the pipeline and the impeller are partly blocked or the impeller is defective; Outlet pipe leakage is serious. Remedy: Reduce the head, restore the rated speed, remove the belt dirt and adjust the tightness of the belt; adjust the blade angle, reduce the pump installation position; tighten the gland, seal the leakage of the pump, press packing or replace the packing; remove the plug, Replace the impeller; replace the leak ring and block the leak. The flow rate is greatly reduced. Reason: The filter or bell mouth is gradually blocked by debris; the dynamic water level is lowered, and the depth of water in the inlet pipe is insufficient. Remedy: Remove debris, increase the depth of the bottom valve into the water. During the operation, the water outlet is interrupted. Causes: There is debris in the pipeline or the water inlet; the packing is worn, loose, and the water seal tube is blocked; the impeller is damaged or loosened; Remedy: Remove obstructions, replace the packing, clear the groove of the water pipe, install the water seal ring correctly, tighten or replace the impeller, lower the installation position of the water pump, or wait until the water level rises. Power consumption is too high? Reason: excessive speed; pump shaft bent; debris around the blade; head too high. Remedy: Adjust the appropriate speed; correct the pump shaft; remove debris; try to reduce the head.

Alternating Pressure

Alternating pressure devices typically utilize multiple bladders to facilitate routine patient turning. These devices may also assist the nursing staff to move the patient to change bedding and move the patient out of bed.

Low Air Loss

Low air loss devices are typically powered with blowers that run continuously. Air is allowed to escape through the device in specific areas designed to provide further comfort and treatment of the patient. The blower maintains constant air pressure and inflation of the device.

Static Overlay Mattresses

Static overlay mattresses are filled with a specific volume of air once prior to use. These devices are often used for the prevention and treatment of pressure ulcers (bed sores).
