Wal-Mart Wheel Excavator has the following advantages:
1, through the Department of hydraulic oil flow rate and resistance for careful analysis and calculation, and heat loss and dynamic matching to adapt to, even in the 40 ° ambient temperature, the excavator can still maintain a good working condition. Will not happen high temperature phenomenon.
2, Wal-Mart wheeled excavator pilot oil pipeline to install oil valve, and energy storage device to ensure the stability of the pilot oil pressure, so that the operation more stable. And can be in the state of flameout to release the pressure inside the working device clean and extend the service life of the hydraulic system.
3, the cab all the use of silicone oil shock absorber, the effective transmission of the engine to avoid the vibration, the operation more comfortable.
4, rotary motor for the advanced Seiko original Korean imports. Smooth operation.
5, the pilot handle for the Korean original import, excellent performance
Second, Wal-Mart wheeled excavators and other brands than the more obvious configuration and price advantage.
1, the whole vehicle structural parts are all made of 16 manganese steel. Volvo wheel excavator body plate thickness than other manufacturers are 3-5 mm, boom, stick, bucket, all thickened steel, increased in the same model, the structure is more robust, the use of more rest assured.
2, all bushings are for post-processing, sleeve with the gap maintained at 0.1 mm accuracy. Inset sets, shafts, have been quenched and tempered, James treatment, high wear resistance, within the set of butter groove depth is greater than 3 mm, shaft rotation in the casing can be a long time to form the oil film, the service life of 5 Year or more. The price of the sleeve is more than 10 times the normal sleeve.
3, Volvo wheeled excavator cylinder with buffer import Parker seal cylinder, due to the internal pressure with automatic oil drain buffer valve, when the cylinder pressure for a long time before and after the oil line will be connected to protect the cylinder seal, and The same principle of imported cylinder, so the cylinder will be pressure relief phenomenon, and domestic oil tank for the expansion of the oil seal, the greater the pressure the better sealing, but such a seal will soon damage the cylinder seal, and the action blunt, the vehicle will occur Severe shaking, the hydraulic system will cause a very bad influence.
1, the main pump used in Japan Shimadzu 23cc high-quality gear pump. Life of up to 5 years.
2, multi-channel valve for the state-owned Yangtze River Hydraulic Factory products, stable and reliable quality. Can be imported with Parker multi-valve.
3, the engine is Zhejiang Xinchai A498BZG turbocharged engine, power output up to 48 kilowatts, to ensure that the Contact: Zhang Yong Tel: 18863700188 13853709217
