The same heat conduction oil pump, in the hands of different operators, its use efficiency and service life are different. We can often effectively improve the use efficiency of the equipment and extend the service life of the equipment through some measures. Today, we will introduce how to make your heat conduction oil pump more and longer. 1. When the pump starts, when there is no pressure formation at the outlet, the speed can not be increased blindly to prevent premature damage to the shaft or bearing.
2. Because the pump body operates at high temperature, hinge supports should be set on the piping during cold installation to prevent the piping displacement after heating up.
3. The coupling must be heated up after the pump body to avoid additional torque during operation.
4. The temperature of the heat medium jacket of the pump body can be slightly lower than that of the heat medium temperature of the front and rear clamp sleeves. Because the melt viscosity is a decreasing function relationship with the shear rate, the extrusion of the gear and the shear of the bearing will make the melt temperature rise 3 ~ 5℃ after the pump, and the reduction of the heat medium temperature can prevent the melt degradation. The data show that by reducing the temperature of the bearing area, the bearing capacity of the bearing can be greatly increased. There is no need to replace the large-capacity pump, and the output capacity of the gear pump can be increased by 50% just by increasing the speed.
In addition, it is also very helpful to pay close attention to the working state of the equipment and do a good job in the corresponding inspection to improve the efficiency of the heat conduction oil pump. The inspection work includes: 1. Check the use of the heat conduction oil pump and the temperature of the heat conduction oil in the high groove. It is strictly prohibited to exceed 70℃, so as to prevent coking and leakage.
2. Check whether the value of the pressure gauge, thermometer and flowmeter of the furnace is in normal value, so as to determine the running state of the boiler.
3. The furnace of the coal-fired heating furnace should not have the phenomenon of fire and air absorption. Furnace high temperature heat conduction gear oil pump steel structure state and masonry and furnace door should be intact, always keep the furnace tightness.
4. Circuit inspection of the body of the heat conduction oil pump and the furnace, grate and its auxiliary equipment, to find the problems in time, and to take corresponding measures.
5. Check the operation of all equipment, and there should be no noise in transmission. The lubricating oil of the coal machine hoist on the speed regulating box of the coal grate should be sufficient before the deceleration of the slag machine and the induced draft fan should be filled with lubricating oil, and the cooling water of the induced draft fan should be connected.
