One 9-meter vacuum tank, two 9-meter cooling tanks;


③一个两爪皮带式牵引机;

One 2-claw rubber belt haul-off unit;


④一台高速无屑切割机,一台飞刀切割机两种切割机共同使用(飞刀切割机主要用于16,20,25,32小口径管材的切割,行星切割机主要用于40-110管材的切割)。

One high speed dust free cutter and one flying-knife cutter for the 110 pipe production line,the two cutters could work together(The flying-knife cutter is mainly used for cutting small pipes, like 16,20,25,32mm,the planetary cutter is mainly used for cutting 40-110mm pipes).



主机部分

Extruder


①主机部分主要有电柜、电机、减速机、螺杆、机架、加热圈等组成;

The main parts of extruder: electrical cabinet,motor,gearbox,screw and barrel, machine frame and heaters;


②电柜电气元器件:

Electrical components:

主机变频器用的是KEB变频器;

First, we use KEB inverter;

主电机空开使用的是LG空开;

LG air switch for main motor;

色标共挤机使用的是博士力士乐变频器;

Bosch Rexroth inverter for color strip co-extruder;

整个设备还装有电表,对设备的能耗进行监控,可以知道我们整条线使用一天的产量、使用多少度电;

The line is also equipped with electric meter to monitor the energy consumption , so we can know the output of the whole line , the consumption of electricity for one day;


加热控制部分:

Heating control parts:

PLC集成控制系统使用的是西门子品牌;

We use Siemens PLC;

中间继电器用的是欧姆龙;

OMRON intermediate relay;

低压断路器空开用的是施耐德;

Schneider low voltage breaker and air switch;

加热控制器使用的固态继电器是美国快达;

Crydom solid state relay from USA from heating control device;


③操作电脑屏使用的是西门子触摸屏;

SIEMENS touch screen;


④减速箱使用的是福克减速箱,在开机之前务必要加注220号中负荷齿轮油,减速箱冷凝器的主要作用是给减速箱里面的油脂冷却;

FALK gearbox. We must add 220 medium load gear oil before starting,the main function of condenser is to cool the grease inside the gearbox; 


⑤水流分流器有一个进水口和一个出水口,作用分别是给减速箱和螺杆水套冷却、供水

There is a water shunt below with one inlet and one outlet. It is for cooling gearbox and water bush of screw;


⑥螺杆水套一区的温度不能太高,在开机之前,必须要把水路都打开,温度过高将影响螺杆的吃料、影响产量;

The temperature of water bush must not be very high, so the waterways must be open before starting extruder. If the temperature is too high, it will effect material feeding and output;


⑦我们用的是永磁同步伺服电机,综合能耗要比交流电机和直流电机小、噪音小、稳定;

We use permanent magnet synchronous servo motor which has a better performance of power consumption than AC motor and DC motor;


⑧我们的加热圈用的是保温棉加热圈,保温效果要比普通加热圈更好,对螺杆的塑化、节能都有优势;

This is insulated cotton heater which has a better insulation effect than ordinary heater.It has advantages ofplasticizing and energy saving ;


⑨整体的螺杆使用的是合金螺杆,高产量耐磨稳定、塑化好。

The screw is alloy screw which has advantages of high output, wear resistant, stability and good plasticization.



真空箱

Vacuum tank


①真空箱是九米的真空箱,使用的是两段真空箱,第一段是三米,第二段是六米;

The vacuum tank is 9 meter long with two sections. First section is 3 meters and second section is 6 meters;


②真空泵的控制都采用变频控制,噪音会比没有变频器的噪音要减少

Vacuum pumps are controlled by inverter. It’s noise is much lower;


③真空箱的管路都装有两路过滤器,可以分开使用,如果客户的水质不是特别好,需要定期地清理,可以切换着使用

There are two filters installed in the water pipeline on vacuum tank. The two filter could be used alternatively. If water quality is not good, it needs to clean filters regularly;


④真空排水电磁阀自动排水和球阀手动排水,在开机过程中,手动排水不需要打开,只需要把自动排水打开。真空箱总共有两进两出的进水和排水,分别为上端的进水口和下端的出水口,上端手动进水,一般不需要打开,电磁阀会自动控制进水,有液位和温度两种去控制它的水温和水位;

There are solenoid valve automatic drainage and ball valve manual drainage. In production , manual drainage does not need to open, only need to open automatic drainage. There are two water inlet and two water outlet.The manual water inlet is on the upper side and doesn’t need  to open. Usually the automatic water inlet is controlled by solenoid valve. Water temperature and water level could be monitored by temperature sensor and water level sensor;


⑤我们真空电柜的元器件:力士乐变频器、施耐德、欧姆龙、正泰等一些元器件。

Let’s have a look at our electrical components. There are Rexroth inverter, Schneider,OMRON and CHNT brand elements.


⑥真空箱主要的作用是给管材定型、冷却,我们的9米真空箱要比常规的6米真空箱定型效果和冷却效果更好。

Vacuum tank is used for shaping and cooling pipes. The shaping and cooling effect of 9 meter vacuum tank is much better than that of 6 meter vacuum tank.



喷淋箱

Cooling tank


喷淋箱主要的作用是给管材冷却,喷淋效果比老式的喷淋箱更好;我们装有一组过滤器,可以对里面的喷头、管路进行过滤,防止杂质进入喷淋管中,对喷淋头进行堵塞;箱体的下方分别是一个进水口和一个出水口。

The main function of the cooling tank is to cool the pipe. The spray effect will be better than the old type cooling tank. There is a set of filters which can filter the inside nozzle, pipeline to prevent impurities from getting into the nozzle and pipe. There is one inlet and one outlet, respectively under the box.



牵引机

Haul off unit


我们的两爪牵引机是皮带式牵引机,线速度是按照每分钟35米设计的,电机使用的是台达伺服电机,使用伺服电机对皮带的同步速度更精准,使管材的壁厚偏差误差更小,每根管子的误差能够精准的控制

This is our two claw rubber belt haul off unit. The designed speed is 35m/min. We use Delta servo motor which can ensure precise belt synchronization, so that the pipe wall thickness deviation error is smaller andthe error of each pipe can be accurately controlled;



切割机

Cutter


①切割机采用的是同步带和牵引同步去切割,切割机和牵引机同步切出来的管材端面平整没有白边

This is the planetary cutter which adopts synchronous belt to cut, which could match haul off unit. It canensure neat and flat cutting edge of pipe;


②切割机在每次换规格时,都要去调刀片的刻度,刻度在刀架的右侧内部,每次开机都要调到相应管材外径所对应的刻度;

When change different size, it needs to adjust the scale of blade. Scale is on right side. It needs to adjust to the corresponding scale when produce different size pipe.


③切割机使用的是西门子触摸屏,调压阀是对行星切割机的进刀去调节,主要调节进刀气压,下面的是飞刀电路控制按钮部分;

The touch screen is Siemens brand. Adjusting pressure valve to adjust blade feeding. The below parts are control buttons of circuit of flying knife cutter;


④我们的飞刀切割机使用的是伺服三千瓦电机,每次换规格时,要更换切割机的夹具;
