Diesel engine fire pump market review and prospect
In order to improve the response ability of diesel engine fire pump to fire signal, it is suggested to inspect it once a week. Considering the water hammer effect and the characteristics of the diesel engine itself, we should start the diesel engine at a low speed during inspection, and then slowly accelerate it to the speed required by the fire protection — 1500R/min-3000R /min. When the water temperature and oil temperature reach 60℃, it can be gradually slowed down, but it still needs to run at idle speed for 2 ~ 3min before stopping, so as to avoid the supercharger bearing bite to death due to supercharger overheating when stopping suddenly.Gasoline Portable fire pump
After parking, be sure to adjust the speed to 1500R /min- 3000R /min, in case of fire need. Because the inspection process of diesel engine fire pump is relatively complex, so if there is no special requirements of customers, we generally do not consider automatic inspection in the design process, we suggest users to use manual inspection. Diesel engine fire pump to ensure the reliability of the whole control system, perfect daily management is inseparable. Although diesel engine fire pump has a high degree of automation function, but the artificial damage factors make it lose the function of things often happen. The components are damaged or lost, the parameters of time relays and chargers are incorrectly modified, etc., users have reported. Therefore, the key of the pump room should be managed by a special person, and the equipment parts should be regularly checked whether they are lost or damaged by other factors, and the parameters of each component are scientific and reasonable.Gasoline Portable fire pump
Diesel engine fire pump check whether the bolts loose phenomenon, such as loose should be tightened immediately, check the diesel engine pump set in and out of the water valve, as well as the total water valve, automatic pressure relief valve is in the specified state, check whether the packing is normal, generally allow 1-15 drops per minute. Before starting, close the needle valve of the pressure gauge to prevent damage of the pressure gauge. Put the control button on the control panel into automatic gear, pay attention to the changes of the data on the control panel, if there is any abnormality, stop immediately. Diesel engine fire pump in structure is much more complicated than conventional pump, therefore, before the start of preparation is more complicated, for diesel engine fire pump start correctly in order to ensure the normal work of the fire pump, should first check the diesel engine fire pump control on the voltmeter shows whether is 24 v, if less than 24 v, should be timely find out the reasons, troubleshooting. Check whether the parts of the diesel engine are normal, whether the accessories are reliably connected, and eliminate abnormal phenomena.Gasoline Portable fire pump
Diesel engine fire pump inside the oil pan and fuel injection pump and governor of the oil level of oil meets the prescribed position, if it is found that the oil is insufficient, should add the same model of engine oil, fire pump whether there is enough water in the tank, if the open cycle cooling system, you should turn on the water, with the hand pump on the fuel oil transfer pump, fuel injection pressure to the fuel oil system, Unscrew the fuel injection pump at the same time on the vent screw, remove the air in the fuel oil system, when here no more gas out, tighten the screws, then continue to pump oil until the oil return pipe, after tightening the hand pump, in turn, loosen the high pressure on each cylinder injector tubing connector nut, the governor handle in the diesel engine running, turn the diesel engine, discharge the air in the high pressure oil pipe, For new engines or unused diesel engines that have been parked for more than 5 days, turn the crankshaft for 3 ~ 5 revolutions before starting. Diesel engine fire pump has preheating starting device, and need preheating starting (temperature below 5℃), should also check whether the preheating plug is normal, in order to ensure the correct start of diesel engine fire pump, should be ready before the start of the above 8 points to open the diesel engine fire pump.
