(is a high-tech joint venture, specializing in design, research and development, production, sales, service and reliability of environmental testing equipment, the main product high and low temperature wet heat box, programmable constant temperature and humidity box, step into the environmental laboratory -, WALKING-IN, salt spray box, constant temperature and humidity machine, thermal shock machine, vibration constant temperature and humidity composite test machine, vacuum drying oven, constant temperature constant temperature host and other instruments and equipment. Experienced, and trusted by many domestic and foreign manufacturers With support, the factory set up Shanghai, the network radiates China, and customers are all over the world.
High-quality drying box---Selecting the vacuum drying box for Shanghai simple household equipment Note:
1. Vacuum box (the outer casing must be effectively grounded to ensure safe use.
2. The vacuum box should be used in an environment where the relative humidity is ≤ 85% RH, there is no corrosive gas around, no strong vibration source and strong electromagnetic field.
3, vacuum box () studio without explosion-proof, anti-corrosion treatment, etc., should not put easy, explosive, easy to produce corrosive gas items to dry.
4, the vacuum pump can not work for a long period of time, so when the vacuum reaches the requirements of dry goods, the vacuum valve should be closed first, then the vacuum pump power supply should be turned off. When the vacuum is less than the requirements of the dry goods, then the vacuum valve and the vacuum pump power supply are turned on, and the vacuum is continued. This will extend the life of the vacuum pump.
5. If the dry items are wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent the humid gas from entering the vacuum pump and causing the vacuum pump to malfunction.
6. Dry items should be light weight and small in size (small granules) after drying. Vacuum should be added to the working chamber to prevent the vacuum pump (or solenoid valve) from being inhaled by the dry matter.
7. After the vacuum box is used for many times, it will not be able to vacuum. In this case, the door seal should be replaced or the door buckle on the box should be adjusted to extend the distance. When the drying temperature of the vacuum box is higher than 200 °C, it will produce slow air leakage (except 6050, 6050B, 6051, 6053). At this time, remove the back cover of the box and loosen the heater base with an Allen key to exchange the seal. Circle or tighten the heater base to solve.
8. If the rubber plug of the bleed valve is difficult to rotate, it can be lubricated with a proper amount of grease on the inside. (such as Vaseline)
9. In addition to maintenance, the left side cover (except models 6090 and 6210) cannot be removed to avoid damage to the electrical control system.
10. The vacuum box should be kept clean at all times. Do not wipe the door glass with a reactive chemical solution and wipe it with a soft cotton cloth.
11. If the vacuum box is not used for a long time, wipe the exposed plating parts and apply neutral grease to prevent corrosion. Put on the plastic film dust cover and place it in the dry room to avoid damage to the electrical components. use.
