Profile

Fecal suction truck is a cleaning and professional vehicle which is mainly applied in digestion tank, side bilge, sewer and other environment. Adding to sprinkler and garbage truck, it is called as three major environmental sanitation trucks.

Function declaration: configuration of vacuous fecal suction truck, parts of professional power take off, transmission shaft, vacuous fecal suction pump, moisture separator, oil-gas separator, multiple-directional control valve, suspender, manure tank, releasing valve of manure, suction gun of manure, branch water tank, vacuum pressure panel, net pipe system and others.

The fecal suction truck is mainly used to suck the fecal, sewage, waste mud and the liquid contained with small floating debris, which has the advantages of high-efficiency of suction, self-suction, self releasing and directly irrigation. Fecal suction truck is used to small, medium and large cities and towns environmental sanitation, municipal administration, agriculture, chemical engineering, mining enterprises, residential estate. The vacuum pump can realize self suction and self releasing.

Principal of fecal suction truck carburetor

If you want make the truck keep working, the engine should apply fuel and aspirate continuously. At the same time, the gas and aspirate should be mixed correctly. After the mixed fuel is fired up, the waste gas can be ejected successfully. Thus, the fuel oil need be stored in the fuel tank, which is transmitted in engine by means of oil pump and pipe. In order to prevent the fuel oil from polluting, it is filtrated by filter. Before the external air which contains fine sand enter the engine, it should be filtrated by filter. What you need to compound the clean air and fuel oil is carburetor of fecal suction truck. It is essential.

Technical specification

Working principal of vacuum pump

Before use the Fecal suction truck , we should learn the working principal of vacuum pump firstly . The important part of working principle is the source and stability of motivation. The vacuum should extract the air in the sealed tank during the it is in suction. It makes it negative pressure, which makes use of barometric pressure suck the sewage into the tank by suction gun. When it is discharging the sewage, the vacuum push the outer barometric pressure into the tank, which can make use of air pressure out of the tank.(the continuous working time of vacuum pump can not exceed 30 minutes).

Stream sequence of vacuum pump airflow.

Airflow sequence of vacuum: when it is in suction, the vacuum pump suck the contained humidity into moisture separator. In where the water is divided, the water will flow back toward the tank. In the meanwhile, the air will enter the vacuum pump inlet from the four-valve. In the pump, after the lubricating oil and air is mixed, then, it is extracted by vent. Especially, the mixture will be originally separated by the coarse strainer. After it, the separated oil will flow back oil pump. The mixed air will another separated by oil-gas separator,then, the four-way valve will inject the atmosphere. The manual operated four-way valve can change the direction of airflow, which can realize suction and extraction freely.

Inspection after operation

After the fecal suction truck vacuum pump has finished work, make an inspection work for fecal suction truck according to the working strength of each time to insure the service life and work efficiency in second time.

Inspection of unusual noise

The distinguish between circular cone initiative bearing of reducer and differential reducer.

Reducer bearing generally produces raspy buzz and quack. The sound beat is stable along with the speed changing of the truck.

The front bearing has a bigger noise of the circular cone initiative bearing when the truck is in slide. The rear bearing have a bigger noise then the car is in running.

Noise of differential bearing. It is usually an unchanging cacophony, but its beat is much more assuasive than the noise of the reducer's cone active gear bearing.

How to clean fecal suction truck

1. Firstly, pay attention to the frequency of car wash. Don’t wash them too often, because it is easy to damage the car paint.

2. Washing the car with clean water ,otherwise the sand in the sewage will rub the varnished paint.

3. Using clean specialized car washing towel. The normal towel friction is stronger, it is easy to cause the damage of the paint on the car.

4. Wash the car in a cool, cool place.

5. Paying attention to the waterproof work of some parts of the fecal suction truck when washing the car, such as, horn, headlights, etc, avoiding  the horn failure or the light fogging.

6. Do not wash the car immediately after driving in the summer, otherwise it will cause damage to the engine, you should wait until the temperature of the car is reduced.
