Thermal oil pump structure characteristics and application range

Hot oil pump is an ideal hot oil circulation pump or heat transfer pump, and it is an ideal supporting pump for heat exchange equipment. Magnetic drive non-leakage heat transfer oil pump is based on the original pump to improve the sealing process. Non-leakage high temperature magnetic seal is used to make the heat transfer oil pump have no leakage for a lifetime. The motor shaft and the heat transfer oil pump shaft have no contact and no friction, so the heat transfer oil pump is in operation more than normal The heat-conducting oil pump is low in noise, more stable, and has a longer service life. It eliminates the phenomenon that the heat-conducting oil pump runs, blows, drops, and leaks. The same use temperature can reach ≤400°C. .

Structural features:

The thermal oil pump adopts a self-heating heat dissipation structure, which changes the traditional water cooling structure, makes the structure simple, small in size, saves operating costs, has good performance, and is reliable in use. It is the second generation product developed on the basis of China's digestion and absorption of foreign oil pumps. Basic The structure is a single-stage single-suction cantilever type foot support structure. The pump inlet is axially inhaled, the outlet is vertically upward and the motor is mounted on the base.

The support of the hot oil pump adopts the structure of double-end ball bearing support. The front end is lubricated with lubricating oil, and the rear end is lubricated with grease. There is an oil guiding pipe in the middle to observe the sealing condition and recover the heat conducting oil at any time.

Hot oil pump sealing features:

(1) Adopt the combination of packing seal and mechanical seal. Filler seal with high temperature resistant filler has good thermal adaptability. Mechanical seal adopts high mechanical strength and good wear resistance of hard alloy material. Sealing properties at high temperatures.

(2) The use of imported polytetrafluoroethylene (abbreviated as PTFE) for lip seals has resulted in a leap in sealing performance, a 25-fold improvement in reliability over rubber seals, and excellent corrosion resistance.

(3) Magnetically driven non-leakage thermal oil pump improves the sealing process on the basis of the original pump. Non-leakage high temperature magnetic seal is used to ensure that the thermal oil pump has no leakage for a lifetime. The motor shaft and the heat transfer oil pump shaft have no contact and no friction, so the thermal oil pump is in operation. Compared with the ordinary heat-conducting oil pump, the noise is much lower, more stable, and the service life is longer, which eliminates the previous phenomenon of running, splashing, dripping, and leaking of the heat-conducting oil pump. The same use temperature can reach ≤400°C.

Application range:

Hot oil pump technology is advanced, high efficiency, long-term stable operation without leakage in the hot state, no additional cooling system, safe and reliable use, etc., has been widely used in China's heating body heating system, has entered the petroleum, chemical, Rubber, plastics, pharmaceuticals, textiles, printing and dyeing, road building, food and other industrial fields, mainly used for transporting weak corrosive high-temperature liquids without solid particles, using temperature ≤ 400 °C, is an ideal hot oil circulation pump.
