夏季高温天租冷再生机施工，不少工程人会遇到一个棘手问题：液压泵压力表指针频繁浮动，波动幅度远超正常范围，还可能伴随设备动作卡顿、动力不足。要知道，液压系统是冷再生机的“动力心脏”，压力表浮动过大可不是小问题，处理不及时容易加剧液压元件磨损，甚至导致设备停机。今天就给大家科普冷再生机租赁的高温天实操干货——液压泵表浮动过大的原因及处理方法，帮大家快速解决问题，保障施工进度。

　　During the construction of cold regeneration machines on hot summer days, many engineers may encounter a tricky problem: the pressure gauge pointer of the hydraulic pump frequently fluctuates, with fluctuations far exceeding the normal range, and may also be accompanied by equipment movement stuttering and insufficient power. You should know that the hydraulic system is the "power heart" of the cold regeneration machine, and excessive pressure gauge fluctuation is not a small problem. If not dealt with in a timely manner, it can easily aggravate the wear of hydraulic components and even cause equipment shutdown. Today, we will share with you the practical tips for renting cold recycling machines in high-temperature weather conditions - the reasons and solutions for excessive floating of hydraulic pump gauges, to help you quickly solve problems and ensure construction progress.

　　先搞懂核心原理：冷再生机的行走、铣刨、拌合等动作都依赖液压系统驱动，液压泵作为核心部件，正常工作时压力应保持稳定。炎热天气下，外界高温会让液压油温度急剧升高，这是导致压力表浮动过大的主要诱因。高温会使液压油粘度下降、润滑性能变差，还可能让液压油发生氧化变质，产生杂质；同时高温会影响液压泵的密封性能，导致液压油泄漏，这些都会造成系统压力不稳定，反映在压力表上就是浮动过大。

　　First, understand the core principle: the walking, milling, mixing and other actions of the cold regeneration machine rely on the hydraulic system drive. The hydraulic pump, as the core component, should maintain stable pressure during normal operation. In hot weather, high external temperatures can cause a sharp increase in hydraulic oil temperature, which is the main cause of excessive pressure gauge fluctuations. High temperature can cause a decrease in viscosity and poor lubrication performance of hydraulic oil, and may also lead to oxidation and deterioration of hydraulic oil, resulting in impurities; At the same time, high temperatures can affect the sealing performance of hydraulic pumps, leading to hydraulic oil leakage, which can cause unstable system pressure, reflected in excessive fluctuations on the pressure gauge.

　　要解决这个问题，得遵循“先预防、再排查、后处理”的思路，租赁设备时提前做好准备，能大幅降低故障概率。首先是租赁前的关键准备：选租赁服务商时，必须确认设备的液压系统状态——要求服务商提前检查液压泵、液压阀、油管等核心部件，确保无磨损、无泄漏；同时核对液压油的型号和油量，必须使用符合设备要求的耐高温液压油，避免用普通液压油应对高温环境。建议优先租赁配备液压油冷却装置的冷再生机，这类设备的高温适应性更强，能有效控制液压油温度。

　　To solve this problem, we need to follow the idea of "prevention first, investigation later, and handling later". Preparing in advance when renting equipment can significantly reduce the probability of failure. Firstly, the key preparation before leasing is to confirm the hydraulic system status of the equipment when selecting a leasing service provider. The service provider is required to inspect the core components such as hydraulic pumps, hydraulic valves, and oil pipes in advance to ensure no wear or leakage; At the same time, check the model and amount of hydraulic oil, and use high-temperature resistant hydraulic oil that meets the equipment requirements to avoid using ordinary hydraulic oil to deal with high-temperature environments. It is recommended to prioritize leasing cold regeneration machines equipped with hydraulic oil cooling devices, as these devices have stronger high-temperature adaptability and can effectively control the temperature of hydraulic oil.

　　其次是施工中的预防措施。高温天施工要合理安排作业时间，避开中午11点到下午3点的极端高温时段，减少液压系统长时间高负荷运行。作业过程中，安排专人定时检查液压油温度和压力表状态，一般液压油正常温度应控制在30-60℃，若超过70℃，要立即停机降温。同时注意检查液压系统的散热装置，确保散热风扇正常运转、散热片无灰尘堵塞，必要时可以用高压水枪冲洗散热片，提升散热效率。另外，避免频繁启停设备、急加速或重载作业，减少液压系统的压力冲击。

　　Next are preventive measures during construction. During construction in hot weather, it is necessary to arrange the work time reasonably, avoid the extreme high temperature period from 11 noon to 3 pm, and reduce the long-term high load operation of the hydraulic system. During the homework process, assign a dedicated person to regularly check the temperature of the hydraulic oil and the status of the pressure gauge. Generally, the normal temperature of the hydraulic oil should be controlled between 30-60 ℃. If it exceeds 70 ℃, the machine should be stopped immediately to cool down. At the same time, pay attention to checking the cooling device of the hydraulic system to ensure the normal operation of the cooling fan and the absence of dust blockage on the cooling fins. If necessary, use a high-pressure water gun to rinse the cooling fins to improve the cooling efficiency. In addition, avoid frequent starting and stopping of equipment, rapid acceleration or heavy load operations, and reduce pressure shocks in the hydraulic system.

　　如果施工中突然出现液压泵表浮动过大，要按步骤排查处理。第一步立即停机降温，让设备怠速运转，同时打开发动机舱盖和液压系统散热罩，待液压油温度降至正常范围后再进行排查。第二步重点检查液压油：打开油箱盖观察液压油状态，若发现油液浑浊、有气泡或异味，说明液压油已变质，需立即联系租赁服务商更换符合要求的耐高温液压油，并清洗油箱和滤油器；若只是油量不足，补充同型号液压油即可。

　　If the hydraulic pump gauge suddenly fluctuates too much during construction, it should be checked and dealt with according to the steps. The first step is to immediately stop the machine and cool it down, allowing the equipment to idle. At the same time, open the engine hood and hydraulic system heat dissipation cover, and wait for the hydraulic oil temperature to drop to the normal range before troubleshooting. The second step is to focus on checking the hydraulic oil: open the oil tank cap and observe the condition of the hydraulic oil. If the oil is cloudy, has bubbles or has a strange smell, it indicates that the hydraulic oil has deteriorated. It is necessary to immediately contact the rental service provider to replace it with a high temperature resistant hydraulic oil that meets the requirements, and clean the oil tank and oil filter; If it's just a shortage of oil, just add hydraulic oil of the same model.

　　第三步检查液压系统泄漏情况：仔细查看液压泵、液压阀、油管接头等部位，若发现有液压油渗漏，要及时紧固接头或更换密封件；若油管出现老化、破损，需立即更换，避免因油液泄漏导致压力不稳定。第四步检查液压泵本身：若上述检查都正常，可能是液压泵内部磨损、间隙过大导致压力波动，这时不要自行拆解，要立即联系租赁服务商的专业维修人员上门检测维修，更换磨损部件。

　　Step 3: Check for leaks in the hydraulic system: Carefully inspect the hydraulic pump, hydraulic valve, oil pipe joints, and other parts. If hydraulic oil leakage is found, tighten the joints or replace the seals in a timely manner; If the oil pipe ages or is damaged, it should be replaced immediately to avoid unstable pressure caused by oil leakage. Step 4: Check the hydraulic pump itself: If all the above checks are normal, it may be due to internal wear and excessive clearance of the hydraulic pump causing pressure fluctuations. At this time, do not disassemble it yourself, and immediately contact the professional maintenance personnel of the rental service provider for on-site inspection and repair, and replace the worn parts.

　　这里给租赁冷再生机的朋友提个关键提醒：租赁协议中要明确高温天气下液压系统的维护责任和维修响应时限。靠谱的租赁服务商会提供定期巡检服务，高温天会主动上门检查液压系统的散热和油液状态；若设备出现故障，能保证快速上门维修，减少停工损失。另外，租赁时可以要求服务商配备应急液压配件，比如密封件、滤油器等，以便快速处理小故障。

　　Here is a key reminder for friends who rent cold recycling machines: the lease agreement should specify the maintenance responsibilities and repair response time limits for the hydraulic system under high temperature weather. A reliable rental service provider will provide regular inspection services, and on hot days, they will proactively come to inspect the cooling and oil status of the hydraulic system; If the equipment malfunctions, it can ensure quick on-site maintenance and reduce downtime losses. In addition, when renting, the service provider can be requested to provide emergency hydraulic accessories such as seals, oil filters, etc., in order to quickly handle minor malfunctions.

　　夏季高温天施工，液压系统的稳定是冷再生机正常作业的关键。总结下来，应对液压泵表浮动过大的核心就是“控制油温、保障油质、排查泄漏”。选对靠谱的租赁服务商，提前做好预防措施，遇到问题按步骤排查处理，就能有效避免故障扩大。如果有冷再生机租赁需求，建议优先选择售后完善、经验丰富的服务商，不仅能拿到性能稳定的设备，还能获得专业的高温天操作指导，让工程省心高效推进。

　　The stability of the hydraulic system is crucial for the normal operation of the cold regeneration machine during construction in hot summer days. In summary, the core of dealing with excessive fluctuations in hydraulic pump gauges is to "control oil temperature, ensure oil quality, and investigate leaks". Choosing the right reliable rental service provider, taking preventive measures in advance, and troubleshooting problems step by step can effectively prevent the expansion of faults. If there is a demand for leasing cold regeneration machines, it is recommended to prioritize service providers with comprehensive after-sales service and rich experience. They can not only obtain equipment with stable performance, but also receive professional high-temperature operation guidance, making the project worry free and efficient.
