DZF-6500 vacuum drying oven is a box-type drying equipment for drying materials under negative pressure. It uses a vacuum pump to pump air and dehumidify to form a vacuum state in the working room, reduce the boiling point of water, and speed up the drying speed. It is used for powder drying, material annealing treatment, semiconductor processing, new energy battery test, aerospace component packaging test, electronics. Degassing, dehydration, hardening and drying in the production process of the product.
High temperatur vacuum oven Grouped equipment:
2XZ-15B rotary vane vacuum pump:
2XZ-15B direct-coupled rotary vane vacuum pump is suitable for pumping air and other general gases. The forced oil inlet device of the oil pump is adopted, and the advantage of continuous operation is still available when the air inlet pressure is ≤1.33×103. It can be used alone, and can also be used for booster pumps, diffusion pumps, backing pumps for molecular pumps, maintenance pumps, and pre-pumps for titanium pumps. It is widely used in vacuum metallurgy, vacuum coating, high temperatur vacuum oven, freeze drying, and vacuum dehydration. Gas, vacuum packaging, vacuum adsorption, vacuum forming, food packaging, printing, sputtering, vacuum casting, photovoltaics, aviation technology, chemical industry, electronics, refrigerators, air-conditioning assembly line characteristics and laboratories and other vacuum operations and supporting use. The 2XZ-15B rotary vane vacuum pump is equipped with a gas ballast valve. The gas ballast valve is specially designed to have the function of aerating both the high temperature gas in the fuel tank and the room temperature gas outside the fuel tank, which greatly improves the ability to remove water vapor. The function of gas ballast is to fill a certain amount of gas into the exhaust chamber to reduce the steam partial pressure in the exhaust pressure. When it is lower than the saturated steam pressure at the pump temperature, it can be discharged out of the pump with the air charged, so as to avoid condensation. In the pump oil, it has the function of prolonging the service life of the pump oil and preventing the pump oil from mixing with water. When the gas ballast valve is opened, it still maintains a high ultimate vacuum, and its index reaches and exceeds the index of similar foreign products.
High temperatur vacuum oven features:
- The closed tightness of the box can be adjusted, and the integrally formed silicone door seal ensures high vacuum in the box.
- Compared with ordinary drying relying on air circulation, powdery samples will not be blown or moved by flowing air
- The shortest heating time, compared with the traditional drying oven, the heating time is reduced by more than 50%.
- When the electric heater is used in the vacuum drying oven, wet items will be conductive, so care should be taken to avoid leakage during use. Therefore, the general oven must be grounded to ensure safety.
- Compared with the high temperatur vacuum ovenrelying on air circulation, the powder sample in the DZF-6500 vacuum drying oven will not be blown or moved by the flowing air;
- The heating in the high temperatur vacuum ovenadopts layer spacing heating. Since the heating method adopted in the vacuum drying oven is radiation heating, layer spacing heating can make the heat radiation of each layer of material more uniform, thereby improving the temperature uniformity in the oven.
DZF-6500 vacuum drying oven over-temperature protection system:
- The thermostat stops heating, and there is no heating signal output.
- The AC contactor of the heating system circuit will trip, stopping the power supply to the heating tube.
- It has a single set of temperature monitoring sensor (independent temperature limit protector) to monitor the temperature of the oven working room, and when it reaches the warning value, it will forcibly shut down the heating system.
