华东风机位于山东省济南市章丘区，于2002年专业制作罗茨风机，至今已有16年的制作经验。产品主要有：HDSR系列三叶罗茨风机，HDR系列二叶罗茨风机、HDLH系列、HG系列高转速一体机等，几百种型号可以选择。山东华东风机有限公司的诚信、实力和产品质量获得业界的认可。欢迎各界朋友莅临参观、指导和业务洽谈。

特点：启动快，耗功少，运转维护费用低，抽速大，效率高，对被抽气体中所含的少量水蒸汽和灰尘不敏感，有较大抽气速率，能迅速排除突然放出的气体。这个压力范围恰好处于油封式机械真空泵与扩散泵之间。因此，它常被串联在扩散泵与油封式机械真空泵之间，用来提高中间压力范围的抽气量。这时它又称为机械增压泵。

用途：该机型广泛用于真空包装，真空冶金中的冶炼、脱气、轧制，以及化工、食品、医药工业中的真空蒸馏、真空浓缩和真空干燥等方面。

产品标准附件：机头，电机，进、出口小声器（包含机架或底座），传动装置皮带皮带轮，皮带轮防护罩，弹性接头，单向阀，泄压阀，压力表，地脚螺栓，润滑油。

售后服务：产品三包服务一年，终身售后维修，保用十年。您身边的风机专家，华东罗茨风机！

Debugging of the trilobate blower?

1. The fan to allow total pressure starting or step-down starting, but should pay attention to, the total pressure when starting current is about 5 ~ 7 times of the rated current, step-down starting from is directly proportional to the current square, when power grid capacity is insufficient, step-down starting should be adopted. (when power is greater than 11KW, it is advisable to start with reduced pressure.)?

2. When the fan is in the test car, the product manual should be carefully read to check whether the wiring bbbbbb is in line with the wiring diagram; It is necessary to check whether the working voltage of the supply fan power supply meets the requirements, whether the power supply is missing phase or phase, and whether the capacity of the distributor component meets the requirements.?

3. The number of test vehicles is not less than two, one person controls the power supply, one observes the operation of the fan, and finds the abnormal phenomenon to stop for inspection immediabbby; First check whether the rotation direction is correct; After the fan starts to operate, check whether the running current is in balance and whether the current exceeds the rated current. If there is no normal phenomenon, check the machine. After five minutes of operation, check the fan for abnormal phenomenon and confirm that no abnormal phenomenon is turned on.?

4. When testing the two-speed fan, start at low speed and check whether the rotation direction is correct. When starting high speed, it must wait for the fan to be still before starting, so as to prevent rotation of high speed and cause the switch trip and motor damage.

5. When the fan reaches normal speed, it should check whether the bbbbb current of the fan is normal, and the running current of the fan should not exceed its rated current. If the running current exceeds its rated current, it should check whether the voltage of the supply fan is normal.

6. The motor power required by the rotz fans refers to the high power required for centifugal fan and wind cabinet under certain working conditions. If the inlet is fully opened, the motor can be damaged. Fan test when it is best to inlet or outlet pipe of the valve is closed, gradually open the valve after operation, to achieve the required conditions, and pay attention to whether the working current of fan more than rated current.?
