No matter how good a person's body is, no matter how good his brain is, but his heart is not good, he still has no energy to work. The hydraulic pump is like the heart of the mucking loader. Which is the best mucking loader? The export manufacturer of the muck loader tells that it plays a decisive role in the hydraulic system.
At present, the main gear oil pumps and variable column pumps used in the muck loaders. Gear oil pumps do not require high cleanliness of hydraulic oil, the price is relatively affordable, and the service life is about one or two years. Mainly used on tire slag loaders. The Zhuzhai pump has a high degree of cleanliness of the hydraulic oil, with little oil supply when there is no load, and automatic variable when the load is large. Mainly used in crawler muck loader.
Double gear pump
The hydraulic system should change the hydraulic oil regularly. It is often said that the reverse rotation of the motor is actually the left-hand rotation of the oil pump, because right-hand rotation pumps are currently used. The pressure rating of the oil pump of the mud loader is the hydraulic pressure pumped by the oil pump, such as 20 MPa or 200 kg force. When the pressure of the distributor safety valve is adjusted too high, the oil pump may leak or be damaged after working for a long time after the oil pump pressure is exceeded. Therefore, the pressure of the safety valve is adjusted to within the pressure of the oil pump.
Safety valve
The mud loader believes that some customers report that the vehicle cylinder is slow and boring. This is actually related to the displacement. For example, for a pump with a displacement of 32, the oil pump pumps 32ml of hydraulic oil when the motor rotates once. The more hydraulic oil is pumped per unit time and supplied to the cylinder, the cylinder speed will become faster. Sometimes the fuel tank filter is dirty, causing insufficient fuel supply. At this time, the adjustment of the safety valve is still so fast, which is the problem of fuel supply.
Single gear pump
If the oil pump takes a long time, it will leak internally, and the gear wear displacement will become smaller. At this time, it will be exciting to change to a new pump truck. Reluctant to change the hydraulic oil pump will break down quickly.
