high temperature vacuum pump in mould temperature machine
Recently, a customer asked what type of vacuum pump is good for the mold temperature machine. I'd like to introduce the use and advantages of the high temperature vacuum pump in the mold temperature machine industry. Generally, the heat-transfer oil at room temperature is relatively viscous. When the oil pump is in operation, the flow rate is slow and the pressure is high. When the temperature gradually rises, the heat-transfer oil becomes thinner, the flow rate is faster and the pressure drops.
What kind of vacuum pump is better for mould temperature machine?
The high temperature mold temperature machine adopts the ultra-high temperature resistant vacuum pump, the temperature control range is about 200-350 ℃, the large flow is specially designed to meet the special molding needs, and the high-performance vacuum pump is adopted to ensure the flow and pressure.
1. The high temperature vacuum pump adopts the self heating heat dissipation structure, which changes the traditional water cooling structure, making the structure simple, small size, saving operation cost, good performance and reliable use.
2. The support of high temperature vacuum pump adopts the structure of double end ball bearing. The front end is lubricated by lubricating oil, the rear end is lubricated by lubricating grease, and there is a oil pipe in the middle to observe the sealing condition and recover the heat transfer oil at any time.
3. The high-temperature vacuum pump adopts the combination of packing seal and mechanical seal. The packing seal adopts the high-temperature resistant packing, which has good thermal adaptability. The mechanical seal adopts the cemented carbide material with high mechanical strength and good wear resistance, which ensures the sealing performance under high temperature.
High temperature vacuum pump is specially used for mold temperature machine. The magnetic maximum temperature pump is 350 ° oil and 180 ° water, high temperature resistant pump, heat conduction pump, mold temperature machine pump, vertical high temperature pump and low temperature pump - 100 ° C.
High temperature vacuum pump has the following characteristics:
(1) because the transmission shaft does not need to penetrate into the pump housing, but uses the magnetic field to drive the inner rotor through the air gap and the thin-wall transmission torque of the isolation sleeve, so the leakage collecting channel of the shaft seal is fundamentally eliminated, and the complete seal is realized,
(2) high requirements are used in the design of magnetic materials and magnetic circuit,
(3) the maintenance and repair work of high temperature vacuum pump is very small,
(4) high temperature vacuum pump can only transport medium without particles,
(5) under normal and special use conditions, there is no aging demagnetization phenomenon of high temperature vacuum pump over time,
(6) high temperature vacuum pump should avoid idling to avoid burning of sliding bearing and isolation sleeve,
The above is for you to analyze the characteristics of the high temperature vacuum pump of the high temperature mold temperature machine, hoping to provide you with reference.
