Maintenance and maintenance of the oil pump of the heat transfer oil boiler diesel burner

1. The anti-rust oil in the fuel line of the heat transfer oil boiler and diesel combustion engine should also be removed before use. Connect the fuel to the fuel injection pump pipeline and continuously rotate the camshaft of the fuel injection pump until the tight seat of the delivery valve sprays clean fuel. 2. After using the vacuum oven of the thermal oil tank, be sure to clean and clean the glass window of the vacuum oven. 3. Use the vacuum pump in the correct order to prevent reverse suction. 4. Contain a lot of solvents, please take out most of the solvents and put them in the oven first, and then use the thermal oil boiler diesel burner to vacuum. 5. Wipe off the anti-rust oil on the surface. 6. Remove the anti-rust oil from the speed regulating cavity of the thermal oil boiler diesel combustion engine and the inner cavity of the fuel injection pump, and add the specified lubricating oil. 7. Water will corrode the heat transfer oil pump, so it is forbidden to use the pump to vacuum the water-containing material, and use the pump to vacuum. 8. Reasonable fuel selection. 9. The light oil burner of the heat transfer oil furnace must use an appropriate amount of fuel. 10. The oil pump used in the light oil burner of the heat transfer oil furnace must be clean and free of any impurities and moisture. Operation process pre-start inspection 1. Check whether the heating furnace and its surrounding environment are clean and free of debris, check whether the furnace body, burners, controllers, fire holes, and smoke pipes are normal; 2. Reverse the process equipment and process, and check the expansion tank Whether the oil level is higher than 1/4 to 1/2 level, and whether the thermometer and pressure gauge are normal; 3. Turn on the power supply of the thermal oil boiler diesel burner control cabinet, check whether the voltage is normal, check whether the indicator light and all display instruments are normal ; 4. Adjust the main gas pressure reducing valve and the secondary pressure reducing valve to control the pressure at 0.005mpa. Start 1. Start the heat transfer oil circulating pump (one for transportation and one for preparation, according to the pump operation rules), after starting the pump, it will circulate normally for about 0.5 hours to stabilize the pressure; 2. Press the burner start button and observe the furnace Whether the flame is burning normally. If ignition does not occur, please start the burner again after troubleshooting. Furnace operation 1. Normal shutdown (1) Gradually reduce the temperature, turn off the burner, and stop burning; (2) Wait for the temperature of the hot oil to drop below 70℃, and stop the operation of the hot oil circulation pump (refer to the pump operation procedure); (3) ) Turn off the main power and make a shift record. 2. In case of emergency shutdown, the burner should be quickly shut down and the burner should be removed along the hinge axis of the burner to form a natural ventilation state between the stove and the chimney so that the heat in the stove can be distributed to the heat transfer oil Natural cooling to prevent overheating. Matters needing attention When checking the circuit, please pay attention to check whether there is electricity leakage around the heat-conducting oil furnace and light oil burner. Sufficient oil-electric fire-fighting equipment should be equipped nearby. Do not use water as a fire extinguishing agent. Troubleshooting 1. The temperature of the outlet oil is too high. When the outlet oil temperature exceeds the outlet oil temperature by 20°C or more than 350°C, the computer will flicker over temperature, and the controlled equipment will be forcibly shut down. 2. The flue gas temperature is too high. When the flue gas temperature exceeds the set limit temperature of 300 ℃, the flue temperature is too high indicator will shut down the controlled equipment. 3. Low pressure difference When the oil pressure at the inlet and outlet of the boiler diesel burner is lower than the set pressure difference, the computer will indicate a fault and force the controlled equipment to shut down. 4. Overpressure When the oil pressure of the boiler diesel combustion engine is higher than the set high pressure point, the computer malfunctions and the controlled equipment is forcibly shut down. 5. Power prompt When the system grid voltage exceeds the normal working range (180v-260v), the screen fault prompt will not cause the equipment to interlock. Matters needing attention 1. For the oil and gas heat carrier boiler diesel burner with heat transfer oil as the heat carrier, the system should be equipped with an expansion tank, water storage tank, safety components, measuring instruments and control devices. 2. When the heat transfer oil is put into use, start the circulating oil pump at the beginning of the operation. After running for half an hour, start ignition and heating. The temperature should be raised slowly during the first use, and the temperature should be about 20℃ per hour. When the temperature rises to 180~200℃, and keep it warm for a period of time, it can be used normally. 3. Check carefully during use to prevent leakage of water, acid, alkali and low boiling point substances into the use system. The system should be equipped with a filtering device to prevent all kinds of debris from entering and to ensure the purity of the oil. 4. After half a year of use, the oil should be analyzed once. After long-term use, if poor heat transfer or other abnormal conditions are found, the oil should be analyzed, added or replaced according to the analysis results. Judgment criteria: basic carbon is not more than 1.0%, acid value is not more than 0.5mgk(OH)/g, ignition point change is not less than 20%, viscosity change is not more than 10%, one of which exceeds the standard should be replaced with new oil. 5. In order to ensure the normal service life and heat conduction effect of heat transfer oil, it is strictly prohibited to use it under over temperature. 6. The design and installation of the heating system of the heat-conducting oil furnace and light oil burner shall strictly follow the design regulations of the hot oil furnace formulated by the relevant state departments to ensure the safe operation of the system. !
