Electro-hydraulic motor repair are generally used in portable equipment, or general run smoothly and can provide enough power to mix hydraulic equipment repair road making, such as fans, drills, etc., the advantage is that electricity and convenient. Drawback is the assumption that the stall (no rotor rotation but energized) due to vortex formation and can not rotate, it will cause the coil to burn. The price is relatively cheap. Hydraulic motor is generally used in low speed and high-capacity power can not get a place, such as mixer (transport concrete) can take advantage of a small hydraulic motor torque, similar to the same road mix hydraulic jack repair, a person can take advantage of a very small force support from thousands or even million no problem, so long as the ratio of the design is sufficiently high to facilitate the drive load, low-speed devices such as concrete mixing equipment, usually used in the mixing equipment. Oil temperature is too high: When the hydraulic system, to control the oil temperature, the temperature is too high, it will result in the following phenomena: ① In most cases, when the oil temperature often exceeds 60 ℃, the oil viscosity declined significantly, not only lubricating oil film is thin, increase friction, increased wear, and ring expansion, aging, failures, resulting in the hydraulic system leak. Studies show that the oil temperature is increased seal life is 10 ℃ will be halved. ② posterior mix oil temperature hydraulic repair factory, volume expansion, pressure increases, and the leakage increased with the increase of pressure, so that the leakage increases. ③ temperature rise expansion and contraction of the gap changes. General combining parts of different materials, materials with different coefficients of thermal expansion, when the temperature rise road mix hydraulic repair Which is good, with the expansion and contraction due to changes in different parts, with the gap will change, when the gap becomes larger, resulting in increased leakage Road mixing machine hydraulic repair prices, Hanzhong Road mixing machine hydraulic repair, hydraulic repair Chengtong Xi'an Xi'an Chengtong hydraulic repair Limited.
