商品描述

SB系列离心式砂泵主要是用来给油田钻机的循环固控系统配套，其作用是给除砂器、除泥器、混料器等提供具有定排量和压力的钻井液，以这些设备工作。

  其中ZSB10×8×14离心式砂泵主要适应于配套3000m以上的钻机，且钻井液粘度、比重都比较大的钻井工程使用；ZSB8×6×14离心式砂泵主要配套3000m以上的钻机；ZSB8×6×11离心式砂泵主要配套3000m以下的钻机，也可作为灌注泵给三缸泥浆泵供浆；ZSB6×5×11离心式砂泵般用于车装钻机或小型钻机的配套；ZSB4×3离心式砂泵与计量罐配套，通常称计量泵或补给泵；ZSB3×2离心式砂泵般作为清水泵使用。

 结构特点

离心式砂泵主要由泵壳、叶轮、泵轴、耐磨盘、密封装置、轴承座、轴承、联轴器、电机、底座等组成。该系列离心式砂泵的特点是：

1.开式叶轮，适于输送高粘度的钻井液；

2.组合密封，使用长；

3.所有型号离心泵的轴承座、轴等零部件通用，维修方便、节约成本；

4.主要零部件均为耐磨球铁，树脂砂铸造，使用长、外型美观。

工作原理：电机通过联轴器驱动砂泵的轴转动，轴带动叶轮转动，钻井液经吸入口由叶轮中部吸入，通过叶轮中的流道后，在离心力作用下，获得能量和速度，经过泵壳连续不断地从排出口输送给工作机。

 1. Usage and Application Range

ZSB series centrifugal sand pump mainly supplies to solids control circulating system of oilfield drill rig,and be used to provide drilling liquid with a certain discharge capacity and pressure to sand, desilter and mud mixer,to assure these equipments work efficiently.

The SB10×8×14 centrifugal sand pump applies to over 3000-meter-long drilling rigs，with big viscosity and specific gravity drilling fluid.The SB8×6×14 centrifugal sand pmp applies to over 3000-meter-long drilling rigs.The SB8×6×11 centrifugal sand pump applies to under 3000-meter-long drilling rigs,also can be can be used to supply mud to triplex mud pump as a filling pump.The SB6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or pocket drilling rigs.The SB4×3 centrifugal sand pump is usually used as measuring pump or replenishment pump.The SB3×2 centrifugal sand pump is usually used as clean water pump.

2. Main Structure ,Feature

Its main parts are pump shell, impellers, bearing block, pump axle, bearing, shaft coupling,wearing plate, seal apparatus, oil seal, motor and base.

The Series Centrifugal Sand Pump has these features:

(1) Open impeller,apply to transport high viscosity drilling liquid.

(2) Combination seal for a long service life.

(3) Use universal bearing houses and bearings,convenient to maintain and cut the costs.

(4) The major parts are made from antiwear nodular iron,and long service life.

The prinple is that under the motor, the impellers of the pump rotate at high speed, the dring fluid is sucked into the suction pipe. After the drilling fluid flows through the suction pipe andgets enough energy and velocity under the centrifugal force, the drilling fluid is expelled continuously out of the pump.
