When we buy a hydraulic tamping device, we often don't know what to pay attention to. If we have problems after blind purchase, it will be very troublesome to deal with. Now we invited the technicians of Qingzhou Qingyi Machinery Co., Ltd. to tell us about the election. Things to be aware of when purchasing hydraulic tamping devices.
The hydraulic tamper consists of a hydraulic motor, an eccentric mechanism and a jaw. The hydraulic tamper is driven by a hydraulic motor to drive the eccentric mechanism. The vibration generated by the rotation acts on the material through the jaws to make it dense. The hydraulic tamper has the characteristics of light weight, convenience, flexibility and good compaction effect. Mainly used for compaction of slopes, dams and building foundations. Mainly used for excavators, it can adapt to 5-32 tons of excavators.
Precautions when purchasing hydraulic tamper:
1. Pay attention to whether the motor is produced abroad, which is related to the use effect and life of the motor.
2. The area of the seesaw is not as large as possible. If the motor is too large, it is easy to increase the failure rate. If it is small, it is easy to barely leak the motor. Therefore, do not let the manufacturer change the area of the seesaw at random when purchasing.
3. Whether the main bearing is made in China, it is easy to generate centrifugal force in China, which causes the ball to break and slide.
4. Assembly and machining accuracy. An eccentric wheel is mounted on the vibration tamping main unit. The rotation of the eccentric wheel should ensure that the concentricity is not more than 0.001 mm, otherwise it will be easy to get stuck and not work.
5. The oil seal should be imported from the original. During operation, the rotation of the eccentric wheel tends to cause the coolant temperature to rise. Poor quality oil seals are prone to premature aging and oil leakage.
6. Does the main engine have a regulating valve (commonly known as the relief valve), the key function of this valve is to protect the motor, overload protection, and the customer feels that the power is too large or too small, and can be arbitrarily transferred.
The above is about the matters needing attention when purchasing hydraulic tamping equipment. The hydraulic tamping machine produced by Qingzhou Qinglan Machinery Co., Ltd. has high quality and excellent price, and is sold to many provinces, municipalities and autonomous regions. Welcome customers who need to call to discuss cooperation. .
