Friends who have been engaged in the use of mixer trucks for many years must know that when a concrete mixer truck is working, the hydraulic system heats up very quickly and the temperature is very high, which is very harmful to the vehicle. So what measures should we take to decompress the car when encountering such a situation? Let me tell you today
When the pump truck works for half an hour, use a tap water pipe to pour water onto the hydraulic oil radiator, and the hot air turns into steam instantly. After the car cooled down and restarted, it was found that the heat source was in the main pump. After disassembling the main pump, it was found that this pump uses a left-hand pump oil distribution plate and this pump is a right-hand pump.
The reason for the heating is that the plunger is caused by installing the left-hand oil distribution plate on the right-hand pump. The high-pressure oil at the oil drain end has nowhere to drain.
The main pump heating of concrete mixer trucks can be caused by several factors. These include:
Overloading: When the mixer truck is overloaded with concrete, it puts excessive strain on the main pump, leading to overheating.
Continuous operation: If the concrete mixer truck is used for extended periods without breaks, the main pump can overheat due to constant use and lack of cooling.
Insufficient lubrication: Inadequate lubrication of the main pump's moving parts can cause increased friction, resulting in heat buildup.
High ambient temperature: Operating the concrete mixer truck in hot weather conditions can cause the main pump to heat up more quickly.
To address the main pump heating issue in concrete mixer trucks, the following solutions can be implemented:
Proper load management: Ensuring that the truck is not overloaded with concrete can help reduce strain on the main pump, preventing overheating.
Regular breaks: Providing sufficient rest periods for the concrete mixer truck during operation allows the main pump to cool down and reduces the risk of overheating.
Adequate lubrication: Regular maintenance and proper lubrication of the main pump's moving parts can minimize friction, preventing excessive heat generation.
Cooling mechanisms: Installing additional cooling mechanisms, such as fans or water cooling systems, can help dissipate heat and regulate the main pump's temperature.
Operating within temperature limits: Monitoring ambient temperature and avoiding operation in extremely hot conditions can prevent excessive heating of the main pump.
It is essential to address main pump heating promptly, as prolonged overheating can cause damage to the pump and other components of the concrete mixer truck, leading to costly repairs and downtime.
