Hydraulic breaker-model classification, working principle and precautions
Sep 24,2024
1. Classification of hydraulic breaker models
Hydraulic crushers are also known as crushers and crushers. According to different use needs, they can be divided into various models.Generally speaking, the models of hydraulic breakers include HT10, HT20, HT30, HT40, HT50, etc. Different types of breakers have different working capabilities and scope of application.When choosing a hydraulic breaker, it is necessary to choose the appropriate model according to the excavator model and working environment to improve work efficiency.
2. The working principle of hydraulic breaker
The hydraulic breaker uses a hydraulic pump as the power unit and hydraulic oil as the working material. It is a tool specially used for crushing.The hydraulic breaker converts the liquid pressure into the impact energy of mechanical equipment, and uses this energy to break hard materials such as stones and concrete.The power source of the hydraulic breaker is the pressure provided by the excavator, loader or pumping station.Hydraulic breakers are widely used in quarries, mines, national defense and security engineering construction, road construction, municipal road engineering, engineering construction and other fields.
3. Precautions for hydraulic breaker
1. Appropriate speed: The hydraulic breaker has low requirements for pressure and data flow, so the medium one-way throttle valve can work normally, but if the large one-way throttle valve works, it is not easy to increase the strike force, and it will cause the hydraulic oil temperature to rise abnormally, causing harm to the hydraulic system software.
2. Replace the sealing ring immediately: the sealing ring is a spare part.When the hydraulic system software is damaged, it should be removed and replaced immediately.Otherwise, the hydraulic system software should be removed and replaced immediately.When installing a hydraulic breaker, the pipeline should be thoroughly cleaned and the inlet and pump oil control circuit circulation system should be connected to ensure the frequency and total number of parts of unsalted butter.If grease is added under the suspension of steel drilling tools, the grease will enter the pressure chamber, and the abnormally high pressure oil will enter the hydraulic system software and damage the hydraulic pump.
3. The use of high-quality hydraulic breakers: because the design, manufacturing, testing and other stages of counterfeit and shoddy breakers are prone to problems, and the equipment failure rate is high in use.It is more likely to lead to the destruction of the excavator.
4. Hydraulic residual oil and environmental pollution: Hydraulic oil pollution is one of the main factors that cause common failures of hydraulic pumps.The environmental pollution of hydraulic oil should be determined immediately.Insufficient hydraulic oil can cause cavitation, leading to common hydraulic pump failures and contusion of the piston rod head of the hydraulic breaker.It is recommended to check the amount of oil before use every day.
Fourth, summary
This article introduces the model classification, working principle and precautions of hydraulic breaker.Hydraulic breaker is an essential tool in excavator construction. It has high efficiency and can be widely used in quarries, mines, national defense and security engineering construction, road construction, municipal road engineering, engineering construction and other fields.When using a hydraulic breaker, it is necessary to choose the appropriate model according to the working environment and excavator model, and pay attention to the details and precautions of use to ensure work efficiency and equipment safety.
