Pump Car Maintenance Tips You Need to Know!
The high outdoor temperature in summer is a great test for pump trucks
and pump workers. Here’s the summer maintenance guide for pump trucks.
Engine
The long-term high-temperature working condition easily damages the
engine cylinder gasket seal. In order to better control the engine temperature
of the pump truck, you need to pay attention to the following points:
1. Antifreeze must be used for the engine. The antifreeze must be
within the validity period and the amount of antifreeze must be sufficient;
2. Use regular diesel to prevent the engine temperature from being too
high due to inferior diesel;
3. Check whether the engine belt is worn abnormally, clean the engine
housing, remove oil and dust, and ensure that the engine heat dissipation is
normal.
Piston Coolant
There should be sufficient piston coolant in the washing room of the
pumping unit. During summer construction, the following two points must be
achieved for piston coolant:
1. Piston coolant must be changed frequently. When the piston coolant temperature
exceeds 40 ℃, it should be completely replaced even if it is clean to ensure
that it can cool and contract well;
2. In high temperature environment, the piston coolant should be the
water added with lubricant, which not only ensures the cooling effect, but also
will not cause waste and pollution due to frequent replacement of coolant.
Hydraulic Oil
The high temperature in summer will reduce the viscosity of hydraulic
oil, resulting in poor lubrication effect. At the same time, the components of the
hydraulic system are prone to wear under high temperature, so the working
temperature of the hydraulic oil should be strictly controlled:
1. In the air temperature of about 35 ℃, 46# anti-wear hydraulic oil
shall be selected;
2. Replace the hydraulic oil regularly to ensure the quality and
cleanness;
3. check whether the working condition of the hydraulic oil radiator is
normal. If necessary, spray clean water on the radiator slowly (high-pressure
water gun is strictly prohibited) to assist in cooling.
Lubricating Grease
The viscosity of lithium grease will also decrease under high
temperature environment, so the following two aspects should be paid special
attention:
1. When the temperature exceeds 30 ℃, the 0# lithium base
grease must be used. The unused lithium grease can be well preserved and
reserved for use in autumn and winter;
2. Check whether the lubricating grease distributor has good sealing
effect to prevent the loss of lubricating grease.
Personnel Protection
Pump workers and other front-line workers should take heatstroke
prevention measures:
1. Take protective measures when going out, wear sun visors and cool
clothes;
2. Eat more vegetables and fruits, drink an appropriate amount of salt
water;
3. Always take heatstroke prevention drugs with you. In case of
heatstroke and other emergencies, go to a cool place in time.
