罐体两侧中部设有走台，平时用于搁置吸粪胶管。罐体内部装有防荡板，用以减少车辆行驶所引起的液体的剧烈晃荡冲击对罐体及其车架连接部位损坏。前封头设有视粪管，便于监视装载量，防止超载。后封头底部设有自流阀，平时密封着，清洗罐体时，可打开球阀让污水自流排出。
罐体以刚性连接方式，安装在车架上，两者中间设有缓冲垫，可减轻车辆的振动对罐体的损害。2、真空泵
吸粪车真空泵是吸粪车上的关键元件，主要和取力器，三通四位阀等配合作业实现抽真空和向罐体内加压作业。
目前吸粪车上常用的都是单级旋转油封真空泵，具有安装方便，抽真空度高，效率高等特点。
真空泵主要由泵体，转子及其组建，泵壳，旋片，滑环，轴承盖及密封装置组成，转子为易损件，为了方便拆卸修理，转子回旋中心偏离于泵体中心。
其工作原理是偏心转子在取力器带动下工作，把罐体吸入压缩室，当压力超过排气口规定值后，压缩室自动开启，把压缩空气排出，这样罐体内部空气就被抽出，反复循环，罐体内部就形成真空。
为了保证真空泵正常工作和避免污染，在生产吸粪车的时候还安装了油气分离器和水气分离器来过滤压缩气体中的水汽和油气。3、取力器
吸粪车取力器的运转，是靠发动机动力通过取力器，传动轴来转动，取力器安装于变速器左或右侧部，操作柄上部位于驾驶室中间板。
这种取力器由输入齿轮、输入轴、中间齿轮、中间轴、输出轴、输出齿轮、拔叉轴、拔叉等及操作柄构成。
输入齿轮与变速器输出齿轮是常啮合副。起动真空泵前，将变速器输出齿轮是常啮副。起动真空泵前，起变速器挂入空档，然后启动发动机，分离离合器，打开取力器开关，此时拔叉轴前移，拔叉带动输出齿轮在输出轴上，滑移而与中间齿轮啮合，输出轴靠花键与输出齿轮传给输入齿轮，中间齿轮传递给输..
4、四通阀
真空泵只能逆时针旋转（面对车头），要从容罐内吸入空气，或者向罐内排出空气，就需要利用四通阀。
四通阀分别与罐体、真空泵、回油箱大气相通。四通阀内设有隔板。改变真空泵的吸气方向，当四通阀将罐体与真空泵相连时，粪车即进行排卸作业。
5、水气分离器
水气分离器位于容罐前顶部，后通容罐。它的内部设有输气管其管两侧开矩形孔，供空气出入容罐。在抽吸作业时，容罐内空气从矩形孔出来，体积突然扩大，流速降低，使水分子和空气分离，可减少其对润滑油和机件的危害。
pvc树脂螺旋软管由于质地柔软、颜色透亮、韧性好、有弹力，性同牛筋，因此也被俗称为牛筋管，顾名思议也就是该软管如同牛筋那样有韧性、有弹性、很好的耐磨性而且有透明度。该产品使用温度在-25℃—65℃，由于其生产材料采用的为耐腐蚀、耐老化、耐单层磨损的透明材料，不含任何其它填充料。该产品的承载仅以本身的强度支撑。其主要特点为：（1）质量轻，pvc骨架部分（筋料）、软料部分全透明，农业、工业使用时管内介质一目了然；（2）pvc牛筋管优越的耐低温性是其它任何一种管材无法比拟的；（3）耐候性俱佳，不受春夏秋冬任何季节的影响；（4）弯曲半径小，弯曲自如（4寸管弯曲半径40cm）；（5）耐负压力好，
产品英文详情介绍
the central body is provided on both sides of the walkway, usually for resting fecal suction hose. anti-swing plate fitted inside the tank for reducing severe sloshing impact caused by the vehicle running on liquid and the tank frame connection portion is damaged. provided depending on the dung front head tube, to facilitate loading of the monitor, to prevent overloading. after the bottom has a gravity valve head, usually sealed, cleaning the tank, gravity to open the ball valve allows the discharge of sewage. rigid connection body, mounted on the frame, both provided with an intermediate cushion, vibration of the vehicle can reduce damage to the can body. 2, vacuum pump suction truck suction truck is a key element in the main and take off, four-way valve, etc. to achieve operations with evacuation and pressurization tank body to work. currently suction truck commonly used on rotary seals are single-stage pump, with easy installation, high vacuum pump, and high efficiency. mainly by the pump vacuum, and the formation of the rotor, the pump housing, rotary vane, slip ring, and a sealing device consisting of a bearing cap, rotor wearing parts, easy disassembly for repair, the pump rotor center is offset from the center of the swirl. its working principle is eccentric rotor operating in pto drive, the tank into the compression chamber, when the pressure exceeds a predetermined value of the exhaust port, the compression chamber automatically open, the compressed air is discharged, so that air is drawn inside the tank, repeated cycle, a vacuum is formed inside the tank. in order to ensure normal operation of the vacuum pump and avoid contamination, while also producing suction truck mounted oil separator and a moisture separator to filter the compressed water vapor and hydrocarbon gases. 3, operation of the power take suction truck pto is powered by the engine through a power take off shaft to rotate, mounted on the transmission power take left or right side portion, the upper portion of the handle is located in the cab of the intermediate plate. such power take an input gear, an input shaft, an intermediate gear, intermediate shaft, an output shaft, an output gear fork shaft, the handle and the fork like configuration. the input gear with the transmission output is constantly meshed gear pairs. before starting the vacuum pump, the transmission output is constantly meshed gear pairs. before starting the vacuum pump, the transmission from shifting to neutral, and then start the engine, the disconnect clutch, the power take open switch, then forward fork shaft, an output gear fork drive output shaft, slipping engagement with the intermediate gear, the output shaft by a spline transmitted to the input gear and the output gear, the intermediate gear is transmitted to the input ..4, only the four-way valve vacuum pump is rotated counterclockwise (the front face), the intake air to calm the tank, or discharge air into the tank , it requires the use of four-way valve. way valve and the tank, respectively, the vacuum pump, back to the tank atmosphere. four-way valve equipped with a separator. changing the direction of the suction of the vacuum pump, when the four-way valve connecting the tank to the pump, i.e. for discharge unloading truck. 5, moisture separator moisture separator located at the top front holding tank, through the tank capacity. its internal tube opening is provided on both sides thereof pipeline rectangular hole for receiving the air out of the tank. when the suction operation, the air from the receiving tank rectangular hole out sudden expansion volume, the flow rate decreases, the water molecules and air separation, which can reduce damage to the parts and lubricants.
