Why do you need to clean the pump truck in time?
Anyone who has driven a concrete pump truck knows that the working environment of a concrete pump truck is either in heavy construction or on the highway.Dust is flying everywhere,so a concrete pump truck full of dirt is normal.Many workers believe that not washing the truck is not important as long as the parts and fixtures inside the concrete pump truck are protected.Is it really?
First,the cleanliness of the concrete pump truck does not directly affect the operation of the concrete pump truck,but indirectly affects the life of the equipment in the truck.
Every concrete pump truck has a gearbox,which is a device with heat dissipation function.Under normal circumstances,the air pressure in the gearbox will increase with the production of water vapor,and the valve on the gearbox will be opened to discharge the gas,just like the safety valve of a pressure cooker.Imagine that if the valve on the gearbox is blocked by unclean foreign objects such as gravel,mud,etc.,the water vapor in the gearbox cannot be discharged,which seriously affects the working state of the gearbox,and the lubrication performance and transmission power will decline.The sheet also slips.The inability of the steam to escape will also lead to accelerated dilution of the oil in the transmission,which will further cause valve blockage,leading to a vicious cycle.The gearbox is a very important part in the car body.Once it fails,the concrete pump truck cannot even run normally.
Second,construction machinery such as concrete pump trucks and transfer pumps are equipped with hydraulic oil radiators to cool down the oil temperature in the engine and ensure that the main engine can work normally.
Under normal circumstances,concrete pump trucks will have hydraulic oil cooling fans.If it is not cleaned on time,the attached dirt will affect the heat dissipation of the fan and cause the hydraulic oil to heat up.High temperatures can deteriorate hydraulic fluid and damage seals and hoses.In severe cases,leakage will occur,reducing the viscosity of the hydraulic oil,weakening the lubricating ability,and damaging the seal.Third,when dust and debris are covered in the hydraulic oil tank,the waterproof valve of the injection port will also be damaged.
When dust and debris are covered in the hydraulic oil tank,the water inlet valve will also be damaged,and the pressure gauge,oil pipe,walking platform and other equipment of the oil return filter element will be covered by debris,and the numerical scale will not be visible,which will also affect subsequent maintenance..If it is not cleaned in time,dust and debris will be brought into the oil tank when refueling and replacing the oil pipe,causing the filter element such as the pressure oil and the oil return to be blocked,affecting the oil supply of the oil pump,and the long-term insufficient oil volume will damage the oil pump.As a construction machinery vehicle,the concrete pump truck will generate high temperature and high pressure during the transportation and pumping process,which requires equipment such as gearboxes and hydraulic oil tanks to dissipate heat.If the concrete pump truck is not cleaned in time,the dust on these equipment will affect its heat dissipation,and it will affect the service life of various components in the truck over a long period of time.Therefore,it is necessary to clean it.
