Sewage suction truck has compact structure, reasonable design, stable performance. Hydraulic lift dump function is used for easily dumping all kinds of dirt cleanly; The rear tank door can be started by hydraulic pressure,which is convenient to clean sediment and
coagulation in tank body.Also it can repair and maintain inside of the tank; hydraulic PTO enhances system stability.
For maintenance of sewage suction truck in winter,pay attention to fluid replacement and maintenance of the engine!
Replacement of various oil:
(1) Use a low pour point and good mobility fuel.Viscosity of fuel oil increases at low temperature with poor fluidity and bad atomization of fuel combustion process tends to deteriorate to cause the engine start capacity and power decreased. So in the case of conditions, you should choose a lower pour point oil. The general principle is that the
choice of fuel pour point lower than the ambient temperature of about 5 ℃.
(2) Replace engine oil. Select smaller viscosity engine oil. At low temperatures, the viscosity of the engine oil increases as the temperature drops, fluidity, and therefore should be replaced by smaller viscosity oil to compensate or eliminate such adverse effects.
(3) Replace the variety of winter oil and grease. In winter, to deal with transmissions, reducers, steering gear switch to winter oil, wheel bearing grease replaced with low drop point.
Maintenance of the engine cooling system
(1) Check working conditions of thermostat to ensure that the thermostat works well to prevent the engine water temperature is too low or too high. The engine is often running at a low temperature, it will lead to increased mechanical wear.
(2) Remove scale in water jacket. The engine water jacket cleaning, remove the internal scale to prevent the excessive accumulation of scale, affecting the engine cooling make machine temperature is too high, such as scale from clogging the drain switch, turn on the water does not lead to a net.
(3) Fill antifreeze. The temperature is too low it and conditions permit, you can use antifreeze in the cooling system of sewage suction truck before using thoroughly cleaned, and should choose a good quality, low corrosive antifreeze, antifreeze quality time to avoid corrosion and mechanical phenomena occur.
