1. The discharge pipe of the heat conduction oil pump and its pipe joints should consider the maximum pressure that can be withheld.
2. The pipe layout of the heat conduction oil pump should be arranged as a straight pipe as much as possible, try to reduce the accessories in the pipeline and minimize the length of the pipeline, when it must be turned, the bending radius of the elbow should be 3 5 times the diameter of the pipe, and the angle should be greater than 90 as much as possible.
3. The discharge side of the heat conduction oil pump must be equipped with valves (relief valves) and check valves. The valve is used to adjust the working point of the pump, and the check valve prevents the oil pump from reversing when the liquid is flowing backwards. (When the liquid flows backwards, a huge reverse pressure is created, which damages the pump).
4. Reasonable selection of pipe diameter, large pipe diameter, under the same flow rate, small liquid flow speed, small resistance loss, but high, small diameter of heat transfer oil pump pipeline, will lead to a sharp increase in resistance loss, so that the pressure of the selected heat transfer oil pump increases, the power of the belt increases, and the cost and operating expenses are increased. Therefore, it should be considered from a comprehensive technical and economic point of view.

Summary. The heat transfer oil circulation of the heat transfer oil heater is realized by the hydraulic oil pump. It can be seen that the heat transfer oil heater is very important for the circulation of heat transfer oil!
The internal working pressure has a great relationship with the size of the oil pump in and out of the oil caliber, if the oil pump inlet and outlet of the oil diameter is larger, then the pressure of the heat transfer oil will be greater, and the oil speed of the heat transfer oil will be faster, so as to ensure that the heat transfer oil heater can have a good temperature control effect.
Hello, the working pressure of the heat transfer oil pump can be adjusted!
The main factors that determine the working pressure of the heat transfer oil heater depend on the pressure of the circulating heat oil pump and the diameter of the inlet and outlet oil ports. The heat conduction oil heater should have a large flow rate and a fast flow rate, so the effect of temperature control is better!

(1) Jog the motor, try to see if the motor steering is correct.
2) Start the motor, when the heat conduction oil pump is running normally, open the outlet pressure gauge and the inlet vacuum pump to see that it shows the appropriate pressure, gradually open the gate valve, and check the load of the motor at the same time.
3) If you find that the heat transfer oil pump has abnormal sound, you should stop immediately to check the cause.
4) During the operation of the heat conduction oil pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the maximum temperature shall not exceed 80C.
5) Try to control the flow and head of the heat transfer oil pump within the range indicated on the sign, so as to ensure that the heat transfer oil pump runs at the highest efficiency point, so as to obtain the maximum energy saving effect.
6) Regularly check the wear and tear of the bearing and seal of the heat transfer oil pump, and replace it in time after the wear is large.
7) When the heat conduction oil pump is used in the cold winter season, after stopping, the oil drain plug at the lower part of the pump body needs to be unscrewed to clean the medium. Prevent the heat transfer oil from freezing and cracking the pump due to moisture.
8) If the heat conduction oil pump has been out of use for a long time, it is necessary to disassemble all the pumps, wipe off the water, and coat the rotating parts and joints with grease to properly protect them.
9) When the heat conduction oil pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.
10) The lubricating oil of the heat conduction oil pump shall be replaced after 100 hours within the first month of work, and the oil shall be changed once every 500 hours thereafter.
11) Always check whether the support points of the inlet and outlet pipelines of the heat transfer oil pump are loose to prevent the heat transfer oil pump from bearing external force due to insufficient support.

The selection of heat conduction oil pump should be considered from five aspects according to the process flow, water supply and drainage requirements, namely liquid transportation volume, device head, liquid properties, pipeline layout and operation conditions.
Calculation of effective cavitation allowance and type of suitable pump: chemical properties, mainly referring to the chemical corrosivity and toxicity of liquid medium, are an important basis for the selection of heat transfer oil pump materials and the type of shaft seal. Liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties include temperature c density d, viscosity u, diameter of solid particles in the medium and gas content, etc., which involves the head of the system.
The head required by the device system is another important performance data for pump selection, and the head should be selected after amplifying the margin of 5%-10%.
There are many contents of the operating conditions, such as the operation of the liquid t saturated vapor force p, the suction side pressure ps (absolute), the discharge side vessel pressure pz, the altitude, the ambient temperature whether the operation is interstitial or continuous, and whether the position of the heat transfer oil pump is fixed or removable.
Some data such as the highest liquid level on the discharge side and pipe specifications and their length, materials, pipe fitting specifications, quantity, etc., in order to calculate the comb head and check the NPSH. The pipeline layout conditions of the device system refer to the liquid feeding height, the liquid delivery distance, the liquid delivery direction, the lowest liquid level on the suction side, and the selection of the pump, based on the maximum flow rate, taking into account the normal flow rate, and when there is no maximum flow rate, the times of the normal flow rate can usually be taken as the maximum flow rate. Flow rate is one of the most important performance data for selecting heat transfer oil pumps, which is directly related to the production capacity and conveying capacity of the whole device. For example, in the process design of the design institute, the normal, minimum and maximum flow rates of the pump can be calculated.
The support of the heat conduction oil pump adopts the structural form of double-ended ball bearing support, the front end is lubricated with lubricating oil, the rear end is lubricated with grease, and there is an oil guide pipe in the middle to observe the sealing situation and the best heat conduction oil at any time. Eddie machine heat conduction oil pump adopts self-heating heat dissipation structure, changes the traditional water cooling structure, makes the structure simple, small size, saves operating costs, good performance, reliable use, is the second generation of products developed on the basis of China's digestion and absorption of foreign oil pumps, the basic structure form is a single-stage single-suction cantilever foot support structure, the inlet of the pump is axial suction, the outlet is centered vertically upward, and the motor is installed on the base.

1. Shutdown: cut off the power supply. Drain the liquid in the heat transfer oil pump, clean it and rotate the impeller 180 degrees regularly to prevent shaft deformation until the oil pump is completely cooled.
2. The heat conduction oil pump must use the appropriate fuel number. Generally, No. 0 diesel is used in summer, and -No. 10 light diesel is used in winter.
3. The fuel used by the heat transfer oil pump must be clean and must not contain any impurities and moisture. 4. It is normal to have a small amount of leakage at the beginning of the operation of the heat conduction oil pump, and the leakage will be reduced or stopped after a certain period of time when the sealing surface is closed. Because the heat conduction oil pump shaft is provided with a packing box at the front end, the sealing performance is more reliable, and a mechanical seal device is arranged in the bearing seat at the same time, so a large amount of leakage is not possible, and a small amount of leakage can be discharged and received through the leakage nozzle.
5. The heat transmitted by the conveying medium to the pump cover and bearing of the heat conduction oil pump is dissipated by the surface of the pump cover and the bearing seat, so that the temperature of the bearing seat is adapted to the temperature of the shaft sealing performance. Therefore, when selecting the installation position of the heat transfer oil pump, the heat of the pump cover and bearing seat should be easily diffused, and there will be no heat storage phenomenon.
6. Two ball bearings are arranged in the bearing seat, a ball bearing on the pump impeller side of the heat conduction oil pump is lubricated with the heat conduction oil conveyed, and a ball bearing on the coupling side is lubricated with high temperature grease: after 3000 hours of operation, each ball bearing must be removed and cleaned with diesel oil, check whether the contact surface is damaged, and if there is damage, a new bearing must be replaced. When installing the ball bearing on the impeller side, the side with the dust cap should be installed towards the impeller, and the heat conduction oil should be injected to lubricate the machine before starting.
The ball bearing on the coupling side is lubricated with compound calcium-based high-temperature grease, and when the bearing is reinstalled, the side with the dust cap should also be installed towards the impeller side, and the grease should be filled during installation. After 48 hours of bearing operation, a grease gun is used to fill the pressure injection cup on the bearing cover with refill.
7. Do not use the gate valve on the input pipe to adjust the flow rate to avoid cavitation.
8. The heat conduction oil pump should not be less than 30% of the design flow rate for continuous operation, if it must be operated under this condition, it should be installed at the outlet bypass pipe, and the flow rate reaches the above minimum value.
9. Always check the looseness of the anchor bolts, whether the temperature of the pump casing of the heat conduction oil pump is consistent with the inlet temperature, the fluctuation of the outlet pressure gauge and the vibration of the pump.
10. Pay attention to whether there is any noise in the operation of the heat conduction oil pump, and deal with it in time if the conduction state is found.
