一、开机前的准备

I. Preparations before startup
1、皮带(联轴器)校正:如www.878365.com是采用皮带传动,则皮带的松紧度应为10~20毫米之间,如www.878365.com是联轴器传动,装置好后应手盘动电机及主机并查看联轴器转动时的均衡度。www.878365.com联轴器根本都采用弹性联轴器,均衡度偏向不大时可疏忽。
1. Belt (coupling) correction: If the air compressor is driven by belt, the belt tightness should be between 10 and 20 mm. If the air compressor is driven by coupling, the balance of the coupling should be checked by hand-disc motor and main engine after installation. Air compressor couplings are basically elastic couplings, which can be neglected when the balance deviation is not large.
2、主机转向校正:如在www.878365.com颐养过程中撤除过主电源,电源接回后应留意电机的正反转,电机的转向应依据主机的转向,东莞www.878365.com主机的正确转向请查看标示在主机上的转向图标.
2. Main engine steering correction: If the main power supply has been removed in the process of air compressor maintenance, attention should be paid to the positive and negative rotation of the motor after the power supply is returned. The motor steering should be based on the direction of the main engine. For the correct steering of the main engine of Dongguan air compressor, please check the steering icon marked on the main engine.
校正办法:交流三相电中的恣意两条电源线即可。
Correction method: Two arbitrary power lines in three-phase AC power supply can be used.
二、机组内压校正
II. Internal Pressure Correction of Units
机组内压应在0.2~0.45Mpa之间。
The internal pressure of the unit should be between 0.2 and 0.45 Mpa.
校正办法:该压力值应在机组卸载运转时停止,值的大小在最小压力阀的调理螺母上调理,为了便当读取所调定的值,应在最小压力阀之前取压力检测点并装置压力表(局部微电脑控制器有内压参数显现功用,如没有该功用的应在最小压力阀之前装设压力表)。Correction method: The pressure value should stop when the unit is unloading and running. The value should be adjusted on the adjusting nut of the minimum pressure valve. In order to read the adjusted value conveniently, the pressure detection point should be taken before the minimum pressure valve and the pressure gauge should be installed. (Local micro-computer controller has the function of showing internal pressure parameters, if not, the pressure gauge should be installed before the minimum pressure valve.

三、加载、卸载、比例值校正
3. Loading, unloading and scale correction
设置该三种参数时,应首先肯定卸载值,卸载值应依据www.878365.com的额定压力和用气端所需的压力分离肯定,肯定好卸载值后,再设定加载值,两者的压差应为0.1~0.2Mpa之间,设置好www.878365.com的卸载和加载值后,最后设定比例值,比例值应设在卸载值与加载值中间,举例阐明:如某工厂需求www.878365.com的供气压力0.8Mpa,并且供气请求相对稳定,则应如下设置三种参数:卸载压力设定0.8Mpa,加载压力设定0.65Mpa,比例控制压力设0.73~0.75Mpa之间。
When setting these three parameters, the unloading value should be affirmed firstly. The unloading value should be separated and affirmed according to the rated pressure of the air compressor and the pressure required by the gas terminal. After the unloading value is affirmed, the loading value should be set again. The pressure difference between the two should be between 0.1 and 0.2 Mpa. After setting the unloading and loading value of the air compressor, the final setting of the proportional value should be between the unloading value and the loading value. An example is given to illustrate the ratio value. Ming: If a factory needs air compressor supply pressure of 0.8Mpa, and the supply request is relatively stable, three parameters should be set as follows: unloading pressure of 0.8Mpa, loading pressure of 0.65Mpa and proportional control pressure of 0.73-0.75Mpa.
校正办法:在微电脑控制器中设置该参数(如www.878365.com的控制采用按扭控制的,则加载与卸载参数应从压力开关调理,比例值应在减荷阀上的比例阀的调理螺母处调理该值)。
Calibration method: Set this parameter in the micro-computer controller (if the control of air compressor is controlled by press-twist, the loading and unloading parameters should be adjusted from the pressure switch, and the proportional value should be adjusted at the regulating nut of the proportional valve on the relief valve).
四、高温维护值效正
IV. Correction of High Temperature Maintenance Value
螺杆式www.878365.com正常工作时,其温度应在65~98℃之间。温渡过高维护的自动停机温度不得超越105℃。
When the screw air compressor works normally, its temperature should be between 65 ~98 C. Temperature over high maintenance automatic shutdown temperature should not exceed 105 C.
