| Boiler feed pump failure | GC boiler feed pump reasons | Boiler feed pump troubleshooting |
| 1, the pump does not absorb water, pressure gauge and vacuum gauge pointer violently beating. | Injected into the water pump is not enough, plumbing or instrumentation leaks. | Continue to pump water, tighten the plug leak. |
| 2, the pump does not absorb water, the vacuum gauge indicates a high degree of vacuum. | At the end of the valve is not open, or has been blocked, suction pipe resistance is too high, water absorption height is too high. | Correct or change the end of the valve condition, change the suction pipe, reduce the water absorption height. |
| 3, pressure gauge pressure, however, the pump is still not water. | Outlet pipe resistance is too large, the motor rotation direction is not correct, the impeller is blocked, the pump revolution is not enough. | Check or shorten the direction of rotation of the water pipe and motor, cleaning the impeller to increase the pump speed. |
| 4, the flow below the design requirements | Pump or pipe blockage, seal ring wear too large, insufficient number of revolutions. | Clean the pump and piping, replace the seal ring and increase the pump speed. |
| 5, the pump consumes too much power. | Gland packing is too tight, stuffing box fever impeller wear, pump water supply increased. | Relax packing gland, change impeller, increase pump resistance to reduce flow. |
| 6, abnormal sound inside the pump, the pump is not on the water. | Flow is too large, suction pipe resistance is too large, there is air at the suction into the suction liquid temperature is too high. | Increase the outlet pipe resistance to reduce flow, check the pump and water pipes, valve at the end, plug the leak, reduce the suction height. |
| 7, pump vibration. | Pump and motor displacement, or bearing bending. | Proofing pump and motor shaft centerline, replace the pump shaft. |
| 8, the bearing temperature is too high. | Without timely refueling, pumps and motors are not in the same centerline, bearing rust. | Refuel, proofing pump and motor centerline, check cleaning bearings |
Shoe polish is a kind of product used to polish, repair leather shoes or boots, and strengthen their waterproof power, which can extend the life of shoes. Shoe polish is usually wax or paste. The utility model relates to a preparation for wiping the surface of leather shoes to make them clean and bright. It can be divided into liquid, emulsion, semi-solid and solid. The main component is wax.
Shoe polish is a substance used to shine and protect leather shoes. It can come in various forms such as paste, cream, or liquid and is typically made from a combination of wax, oil, and pigment. The polish is applied to the shoe using a brush or cloth and buffed to a shine. It helps to protect the leather from water damage, scuffs, and scratches, and can also restore the color of faded or worn-out shoes.
After applying shoe polish to the leather upper, the solvent evaporates, leaving a thin wax film, which can achieve the goals of waterproof, insect proof, shiny, protective leather, and enhancing aesthetics.
