First, there is a skill to drive the sewage pump to save fuel In order to save fuel, the sewage suction truck should combine the performance of the vehicle it is driving in, and stick to the economical speed, that is, no express trains or low-speed vehicles or old carts. Some drivers think that the accelerator is stepped on regardless of which gear it is traveling in, and it is thought that the higher the speed, the more fuel-efficient it is. In the process of driving, some drivers did not dare to step on the gas to drive the vehicle at too low a speed in order to save fuel. In order to save fuel, the sewer truck should adjust accelerator pedals at any time in accordance with the conditions of roads and road conditions, traffic flow, climate wind direction, and vehicle load quality at the time of driving on highways, and keep them within the economical operating speed range as much as possible. If the driving resistance increases, and the traffic is complicated, and the highest gear cannot be used, the low gear should be replaced in time and keep running in the economic range of the low gear. As a driver, it is necessary to continuously accumulate experience in production practices, flexibly use economic speed, and create excellent fuel-efficient benefits. Second, sewage suction vehicle inspection and repair There are five steps in the removal of the steering wheel from the suction truck: 1) Park the vehicle (front wheel) straight forward. 2) Disconnect the negative battery cable and wait for a while. 3) Remove the driver's airbag module from the steering wheel by removing the hexagon socket bolts on the steering wheel using the Allen wrench. 4) Disconnect the connector on the airbag. 5) Remove the steering wheel fixing bolts and use the steering wheel puller to remove the steering wheel. To install the driver side airbag spiral cable, the key step is to align the spiral cable to my middle position. The specific installation method is as follows: 1) First screw the spiral cable to the combination switch mounting bracket. 2) If the spiral cable is fixed in the original position with tape, the intermediate position alignment step will be ignored when installing the spiral cable. The steering column upper guard and steering column lower guard can be installed directly, and the steering wheel can be installed after the needle. 3) The alignment method in the middle position is: Rotate the spiral cable clockwise (or anti-clockwise) until it stops, then turn it counterclockwise (or clockwise) 2 to 2.5 turns until the middle mark aligns with the adjustment mark. Third, the sewage pump diesel fuel filter maintenance and maintenance Daily use of the diesel fuel filter of the Sewage Pump We should note that the diesel filter or the filter element must be replaced every 20,000 kilometers. If the fuel impurity content is large, the travel distance should be shortened accordingly. The arrow on the fuel filter housing indicates the flow direction of the fuel. When installing the fuel filter, no flipping is allowed. In addition to remind drivers friends: filter replacement is best for professional maintenance personnel to carry out. Fourth, sewage suction car replacement The quality of oil at any quality level will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. In order to avoid the occurrence of failure, it is necessary to change the oil regularly in combination with the conditions of use, and to make the amount of oil moderate (usually the upper limit of the oil scale is good). When the oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, it will burst the filter element or open the safety valve. Passing the bypass valve will still bring the dirt back to the lubrication area, which will promote the wear of the engine and increase the internal pollution. Keep the crankcase well ventilated Most of today's suction-supplied gasoline engines are equipped with PCV valves (case cranking forced ventilation) to promote engine air exchange, but contaminants in the helium gas “can deposit around the PCV valve, which may cause the valve to clog. If the PCV valve is clogged, Contaminated gas flows backwards into the air filter, contaminates the filter element, reduces the filtration capacity, and causes the intake mixture to become dirty, causing further contamination of the crankcase, resulting in increased fuel consumption, increased engine wear, and even damage to the engine. Maintain PCV regularly to remove contaminants around the PCV valve

Both of the above approaches are incorrect and both will increase fuel consumption.
Sludge car diesel fuel filter is generally divided into two kinds of removable and rotary, in appearance is mainly composed of an aluminum shell and a stainless steel bracket, and then mounted on the bracket with efficient filter paper, it is placed in the fuel pump and In the pipeline between the throttle inlet and the oil inlet, when the diesel enters the filter, it passes through the filter paper and collects in the filter cylinder, and then enters the fuel pump through the oil outlet, and the impurities deposited on the bottom of the casing are Moisture is released from the oil drain plug in the lower part of the housing.
