The advantage of the oil pump in supporting the frequency conversion motor is that it can effectively control the flow rate of the oil pump and the circulation velocity of the heat conduction oil pump, and protect the normal and stable work of the oil pump. After the oil pump is installed, the motor power supply and frequency conversion interface should be connected with 380V power supply, so as to effectively save electricity. When the power supply voltage is unstable, the voltage can be adjusted by the frequency converter of the oil pump inverter motor to ensure the normal operation of the oil pump. According to the actual working condition temperature demand, the flow rate of the heat conduction oil pump can be adjusted by adjusting the frequency converter of the motor of the heat conduction oil pump, so as to achieve the purpose of controlling the flow rate of the heat conduction oil pump. However, the adjustment revolution of the oil pump generally cannot be lower than 1450r/min. If the adjustment revolution of the oil pump is too low, the oil pump will not absorb the medium.
Prevention and treatment of seal leakage of high temperature oil pump:
1, the gland installation is not accurate, plugging the leakage hole on the front cover and back cover.
2. The outer diameter of the sealing ring is too loose with the aperture of the sealing seat.
3, the direction of the pump body is reversed, so that the oil pressure port is connected to the unloading ditch, and the pressure is formed to flush out the sealing ring.
4, the oil quality is not clean, return oil is not smooth.
5. The tubing thread is not tight. As an important part of high temperature oil pump, the seal of high temperature oil pump plays the role of fixed spindle and sealing medium. If leakage occurs, first check whether the selection and installation of the seal is accurate, and then check whether the working condition is running smoothly
Heat pump using the heat radiating structure, changed the conventional water cooling structure, so as to achieve simple structure, small volume, saving operation capability and good function, use and reliable, is our country on the basis of digesting and absorbing foreign oil pump of the second generation product, the basic structure for the single stage single suction cantilever feet support structure, the entrance of the pump is axial suction, exports for the central vertical, loading with motor On the base.
