The United States vigorously (Darley) the use of pump maintenance Power company's pumps, such as HM500, PSP1000, KSP1000, PSE1000, KSE1000 is a high speed single-stage centrifugal pump, pump and gear box. Which HM500, PSP1000, KSP1000 for power take-off drive, PSE1000, KSE1000 as the engine drive. 1, Lubricating pump The oil in the gear box should be added to the oil line position shown on the tank plug. Check the fuel level every 25 hours (or every 6 months) and change the oil every 50 hours (or every 12 months). Gearbox using 80W / 90 gear oil. Note: Do not add fuel too full! Add oil every other year. 2, packing seal pump can only use the company's molding stuff, number PA926. When adjusting the packing, avoid voids and compact the packing. When it is necessary to fill the empty stuffing box, remove the packing bolts and gland nuts, insert the long spherical packing into the packing guide, and then install the gland nuts and packing bolts. Use a wrench to tighten the packing bolt and press the packing into the stuffing box. Do not use power tools. Rotate the shaft of the pump by hand and continue to fill the packing until there is resistance to rotation, indicating that the stuffing box is full. Continue tightening the packing bolts with a wrench until a small amount of packing comes out of the gap between the pump shaft and stuffing box. At this point the pump can start working, after the water diversion, the pump outlet pressure rose to 0.4Mpa, work under pressure for 10 minutes, tighten the packing with a wrench until the cold water flows between the pump shaft and stuffing box, the amount of leakage in general 5-60 drops per minute. Before working at high pressure, the pump must ensure that cold water runs out of the pump shaft and stuffing box during operation at 0.4 Mpa pressure. So that the pump under normal conditions of high pressure operation for 10 minutes, this time should be sufficient water from the pump shaft and stuffing box outflow between the pump shaft to avoid overheating, not to pump the packing is tight, should The outlet pressure down to 0.4Mpa, and re-tighten the packing bolts. When the packing is filled, always check the dripping frequency of the water drop when the pump is running. If necessary, adjust it to get a constant dropping frequency. 3, Matters needing attention â‘´, unless it is necessary to divert water immediately, otherwise do not let the pump run in the case of no water. ⑵, after the pump water, the engine should be gradually accelerated, do not suddenly increase the throttle. When the engine downtime should be gradually slow down. ⑶, pay attention to the engine temperature, overheating signal should take appropriate measures. â‘·, the most common pump suction is the suction tube leakage failure. ⑸, the pump should be completed immediately after each drain drain valve to open the water, especially in the cold season. Do not forget to close the drain valve after draining the remaining water, otherwise it will lead to the next water diversion failure. ⑹ Do not allow the pump to operate for long periods of time with the water outlet completely closed. ⑺, pump gearbox oil should be added to the oil line shown in the oil position. â‘» Inspect the fuel every 25 hours (or every 6 months) and change the oil every 50 hours (or every 12 months). ⑼, so that all the suction valve and drain valve flexible and easy, easy to operate. ⑽, pump finished salt water, it should immediately wash the pump with water to avoid rust. ⑾, pump water from the ponds, rivers, lakes and other water, to ensure clean water and separate with other debris. â‘¿, the cold season pump and other fire-fighting equipment should be placed in a warm place.ä¸. Less frequently used fire pumps should be regularly inspected and operated to ensure emergency handling. â’, the end of the suction pipe should be installed filter, so as not to inhale foreign body. â’‚, the free end of the suction pipe must be submerged in water to a suitable depth to prevent air from entering the pipe. Especially when the flow rate of the pump is large, it must be immersed in the necessary depth. When the immersion depth is small, the air enters the pipe and forms a small vortex on the surface of the water. When the pump is working at maximum flow, the recommended minimum immersion depth is 4 times the pipe diameter. When it is not possible to have a suitable immersion depth, place a baffle at the end of the suction pipe to prevent air from entering. â’ƒ, suction pipe end not too close to the bottom of the water, or it is easy to be blocked, the general should be 0.3m distance. â’„, excessive suction pipe on the negative pump, in addition to increasing the friction loss and reduce the flow, but also have cavitation.
