We call distribution valves either distributors or multi way valves. The importance of this component is mainly reflected in the sensitivity displayed in the operation output and combination action of excavators during daily operation and use. Here, we want to tell all machine owners that the work of distributors is not simple, just the operation of actions to give action instructions to excavators. Distribution valves can fully demonstrate efficiency and fuel consumption. Domestic sub factories can already make components that most manufacturers can match, and the price is low. Many customers who have problems with distribution valves will replace the sub factory instead of using the original factory if they cannot be repaired, and the price of the original factory is much higher than that of the sub factory. But here, it is often a problem with the performance of the distribution valve that there is an increase in fuel consumption and the action connection is not smooth, and even the action is unstable after replacing the distribution valve.
The key point here is how to detect problems and faults in the distribution valve when purchasing a second-hand excavator. Firstly, it is necessary to observe with the naked eye. The distribution valve is usually located in the center and back of the excavator equipment, and there is basically no collision at this position. Therefore, for equipment that is relatively recent, the distributor can be easily identified at first glance based on the age of the vehicle. The distribution valve involves many pipelines, and the manufacturer will mark the standard interface on the pipeline. If it is possible to clearly identify with the eyes, then this equipment is a genuine and nearly new machine. Setting aside various factors such as pipeline replacement, the possible problems with distribution valves can be roughly divided into two types: oil leakage and blockage. The first type is more common in daily work due to temperature and aging issues. Oil leakage can be easily resolved by replacing the sealing ring.
The second type of problem is more complex, and in situations where the cause cannot be distinguished in detail, major repairs are essential. The distributor, as the central control of the excavator's entire movement, operates the precision large components and carries the control system of the entire excavator system. Although it cannot be said that the brain can be equated with the central nervous system, once a problem occurs that causes the entire excavator equipment to be paralyzed or unable to work properly, the serious consequences if ignored are self-evident.
Inducing reasons for blockageMore than 90% of them are caused by daily maintenance and hydraulic oil pollution, as well as mechanical equipment aging and other problems. Carelessness and spending a lot of money to make up for it is too late. Early detection and treatment are the compulsory courses for daily use of excavators.
The recognition function of the distribution valve through visual observation is minimal. It mainly involves operating the excavator equipment to perform a series of combination and matching actions to comprehensively micro operate and perform large actions in accordance with the various performance aspects of the excavator. Each part must undergo meticulous micro operations to detect any malfunctions. In the market, aging hydraulic oil and internal structural corrosion of old equipment may cause damage to distribution valve components.
The Huacheng second-hand excavator market has its own set of testing and maintenance equipment for distribution valves, which ensures the normal construction of the equipment through complete machine maintenance. Especially in the maintenance of precision components, regular maintenance and testing should be carried out to avoid equipment malfunctions entering the market.
