水泥自上料搅拌车系统气压力不足是因为什么?
What is the reason for the insufficient air pressure of the cement self loading mixer system?
1、如果说水泥自上料搅拌车液压泵有油液输出的情况发生,我们可以及时查看它的工作是不是正常。如果不正常,有可能是压力油路中的某个设备配件其他原因被卡住,处于回油的地方,导致压力油路和溢流回路短路的情况发生,也或许是管接头有松动的情况发生,当我们处在油路中的某些设备漏油严重,或液压缸、液压马达的密封被损坏。排除的办法就是直接拆开有关设备来清洗,看看对应的设备是不是损坏了,该更换就换,该检查就查看一下。
1. If there is oil output from the hydraulic pump of cement loading mixer truck, we can check whether it works normally in time. If it is not normal, it may be that one of the equipment accessories in the pressure oil circuit is stuck for other reasons and is in the place of oil return, resulting in the short circuit of the pressure oil circuit and overflow circuit. It may also be that the pipe joint is loose. When some equipment in the oil circuit leaks seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged. The way to eliminate the problem is to directly disassemble the relevant equipment for cleaning to see if the corresponding equipment is damaged. Replace it when it's time to replace it and check it when it's time to check.
2、看水泥自上料搅拌车液压泵是不是能输出液压油呢。如果说是新的液压泵,没有液压油,可能是泵体有缺陷,让吸油腔和压油腔有相通的情况发生,失去压油能力,应及时找海田重工更换。若不是新的液压泵,无液压油输出,则可能是泵的转向不对,零件磨损严重或损坏,及时更换。
2. See if the hydraulic pump of cement self loading mixer can output hydraulic oil. If it is a new hydraulic pump without hydraulic oil, it may be that the pump body is defective, so that the oil suction chamber and oil pressure chamber are connected. If the oil pressure capacity is lost, it should be replaced by Haitian heavy industry in time. If it is not a new hydraulic pump and there is no hydraulic oil output, the steering of the pump may be wrong, and the parts may be seriously worn or damaged. Replace them in time.
3、水泥自上料搅拌车的液压系统能建立正常压力,一些管路或者液压缸中间是没有压力的,可能就是因为管路、小孔或节流阀、换向阀这些部位堵住了。所以要仔细查看检查压力有没有油液通过,找出原因,然后来排除。
3. The hydraulic system of the cement self loading mixer can establish normal pressure. There is no pressure in some pipelines or hydraulic cylinders. It may be because the pipelines, small holes, throttle valves and directional valves are blocked. Therefore, check carefully to see if there is oil passing through the pressure, find out the cause, and then eliminate it.
4、若水泥自上料搅拌车的液压泵输出流量随压力升高而显着减小,且压力达不到规定值,则是由于液压泵磨损后间隙变大所致。排除方法是测定液压泵的容积效率,就可以确定这个泵是不是能继续使用的,对磨损严重的产品,一定进行修配或更换。
4. If the output flow of the hydraulic pump of the cement loading mixer decreases significantly with the increase of pressure, and the pressure cannot reach the specified value, it is due to the larger clearance after the hydraulic pump is worn. The elimination method is to measure the volumetric efficiency of the hydraulic pump, so as to determine whether the pump can continue to be used. The severely worn products must be repaired or replaced.
