渣浆泵配件是渣浆泵组成局部中不可短少的一局部
 
渣浆泵配件中最重要的为四大过流件,分别是叶轮、前护板、后护板、护套
 
除此之外,轴封、传动局部也都是极端重要的。
 
一、渣浆泵配件----叶轮:
叶轮的作用是将原动机的机械能直接传给液体,以进步液体的静压能和动压能
 
材质采用耐磨耐腐蚀的高铬合金(A05、A07、A33、A49),也有橡胶叶轮
 
渣浆泵叶轮按机械构造分主要有以下方式:闭式、半闭式、开式
 
按其吸液方式可分为单吸式和双吸式
 
二、渣浆泵配件----护套:
护套由于外形酷似蜗牛,又称之为蜗壳
 
材质能够是高铬金属合金材质(A05、A07、A33、A49)和橡胶两种
 
渣浆泵护套依照构造分为两种:
 
单壳泵护套普通直接暴露在外,无其他泵壳维护,护套自身有预留紧固安装,例如:立式渣浆泵、液下渣浆泵、砂砾泵等
 
双壳泵护套普通外部有泵壳维护,其固定主要靠外泵壳压力,例如:ZGB型渣浆泵、ZJ型渣浆泵、分数泵等
 
三、渣浆泵配件----护板:
护板主要作用是与护套配合构成半闭合式流道
 
使渣浆在此空间内运转
 
护板分前护板和后护板
 
渣浆泵前护板与进水管道衔接
 
泵轴穿过后护板与叶轮衔接
 
四、渣浆泵配件----轴封:
渣浆泵轴封是避免泵轴与壳体处走漏而设置的密封安装。
 
轴封型式有:填料密封、副叶轮密封、机械密封三种
 
填料密封具有良好的耐热、耐腐蚀性、弹性大
 
副叶轮密封性能牢靠、价钱廉价、维修便当、适用于保送含有颗粒物较多的介质
 
机械密封走漏量少、工作牢靠、寿命长、应用普遍
 
五、渣浆泵配件----传动局部
渣浆泵的传动局部主要是由轴承和轴承箱组成
 
轴承光滑可采用干油或稀油光滑
 
普通渣浆泵在保送的物质温渡过高或是渣浆泵范围较大的状况下,通常采用稀油光滑。

Slurry pump accessories are an indispensable part of slurry pump components
Among the slurry pump accessories, the four most important overflow parts are impeller, front guard plate, rear guard plate and sheath
In addition, shaft seals and transmission parts are also extremely important.
1、 Slurry pump accessories - impeller:
The function of the impeller is to transfer the mechanical energy of the prime mover directly to the liquid, so as to improve the static pressure energy and dynamic pressure energy of the liquid
The material is made of wear-resistant and corrosion-resistant high chromium alloy (A05, A07, A33, A49) and rubber impeller
According to the mechanical structure, the impeller of the slurry pump mainly has the following forms: closed, semi closed and open
It can be divided into single suction type and double suction type according to its liquid absorption mode
2、 Slurry pump accessories - sheath:
The sheath is also called spiral case because its shape resembles a snail
The materials can be high chromium metal alloy (A05, A07, A33, A49) and rubber
The slurry pump sheath is divided into two types according to the structure:
The single casing pump sheath is generally exposed directly without other pump casing protection. The sheath itself has reserved fastening devices, such as vertical slurry pump, submerged slurry pump, gravel pump, etc
The outer sheath of double casing pump is generally protected by the pump casing, and its fixation mainly depends on the pressure of the outer pump casing, such as ZGB slurry pump, ZJ slurry pump, fractional pump, etc
3、 Slurry pump accessories - guard plate:
The main function of the guard plate is to cooperate with the sheath to form a semi closed flow channel
Make the slag slurry run in this space
The guard plate is divided into front guard plate and rear guard plate
Connection between front guard plate of slurry pump and water inlet pipe
The pump shaft is connected with the impeller through the rear guard plate
4、 Slurry pump accessories - shaft seal:
The slurry pump shaft seal is a sealing device set to prevent leakage between the pump shaft and the housing.
There are three types of shaft seals: packing seal, auxiliary impeller seal and mechanical seal
The packing seal has good heat resistance, corrosion resistance and large elasticity
The auxiliary impeller has reliable sealing performance, low price and convenient maintenance, and is suitable for conveying media containing more particles
Mechanical seal has less leakage, reliable operation, long service life and wide application
5、 Slurry pump accessories - transmission part
The transmission part of slurry pump is mainly composed of bearing and bearing box
The bearing can be lubricated with dry oil or thin oil
In general, thin oil lubrication is usually used when the temperature of the material conveyed by the slurry pump is too high or the slurry pump is large.
