The normal pressure range of gearbox is 1.08 ~ 1.47mpa, and the pressure is lower than 1.08mpa. It is considered that the variable speed oil pressure is too low, which will lead to insufficient driving force of 4-5 square automatic feeding mixer, weak whole machine and no gear start.
减压阀的功效是经由进程压力调理弹簧将较高的输入压力调理到划定的输入压力，并确保输入压力的均衡。一旦减压阀的压力调理弹簧破坏，变速箱将不能保障一般的输入压力。
The function of the pressure reducing valve is to adjust the higher input pressure to the specified output pressure through the pressure regulating spring and ensure the balance of the output pressure. Once the pressure regulating spring of the pressure reducing valve is damaged, the transmission will not guarantee the normal output pressure.
其次，压力调理器不恰当调剂
Secondly, the pressure regulator is not properly adjusted
压力调理阀经由进程压力调理阀芯节制变速器的输入压力。若是输入压力太小，变速箱油压将太低。
The pressure regulating valve controls the output pressure of the transmission through the pressure regulating valve core. If the output pressure is too low, the transmission oil pressure will be too low.
三是管道油封严峻漏油。
Third, the oil seal of the pipeline leaks seriously.
查抄变速箱油盘到变速箱泵吸入管路是不是泄露。若是发明漏油，请补缀或改换新线路。
Check the transmission oil pan to transmission pump suction line for leakage. If oil leakage is found, repair or replace the line.
若何利用4至5方主动上料打金鱼 散热器
How to use the radiator of 4-5 square automatic feeding mixer truck
1.备用散热器的有用环境应对峙透风枯燥。
1. The effective environment of the standby radiator shall be ventilated and dry.
2.硬化处置后，倡议利用软水和硬水，以防止散热器外部梗塞和水垢的发生。
2. After softening treatment, it is recommended to use soft water and hard water to avoid blockage and scale in the radiator.
3.在夏季，为了防止结冰引发的焦点结冰，若是4至5方主动上料打金鱼 永劫候停放或直接遏制，应利用水箱盖和排水开关排挤一切水。
3. In winter, in order to prevent core icing caused by icing, if the 4-5-party automatic loading mixer stops for a long time or stops indirectly, all water shall be discharged by using the water tank cover and drainage switch.
4.水位计应每3个月洗濯一次或按照现实环境洗濯，应掏出部件并用温水和无侵蚀性洗濯剂洗濯。
4. The water level gauge shall be cleaned every 3 months or according to the actual situation. The parts shall be taken out and cleaned with warm water and non corrosive cleaning agent.
5.当散热器完整排空偏重新注满时，起首应将策念头缸体的排水开关扭开，当有水流出时，再将其封闭以防止起泡。
5. When the radiator is completely drained and refilled, first turn on the drain switch of the engine block, and then close it when water flows out to avoid foaming.
6.在平常利用中应随时查抄水位，冷却后遏制水。加水时，渐渐翻开水箱盖，操纵职员的身材应尽能够阔别供水口，以防止高压蒸汽油喷出而致使灼伤。
6. The water level shall be checked at any time during daily use, and the water shall be stopped after cooling. When adding water, slowly open the water tank cover, and the operator's body should be as far away from the water supply port as possible to prevent burns caused by the ejection of high-pressure steam gasoline.
7.散热器不应与任何酸，碱或其余侵蚀性物资打仗。
7. The radiator shall not contact with any acid, alkali or other corrosive substances.
8.在利用防冻液时，为防止散热器的侵蚀，请务必利用惯例厂家出产的持久防锈防冻液，并合适国度规范。
8. When using antifreeze, in order to avoid the corrosion of radiator, please be sure to use the long-term anti rust antifreeze produced by conventional manufacturers and comply with national standards.
9.按照现实环境，用户应完整洁净散热器一至三个月。洁净时，沿反向进气口侧用净水冲刷。
9. According to the actual situation, the user should thoroughly clean the radiator for one to three months. When cleaning, flush with clean water along the reverse air inlet side.
10.在装置散热器时，请勿破坏散热片（切片）和保险杠散热片，以确保散热和密封。
10. When installing the radiator, do not damage the heat sink (slice) and bumper heat sink to ensure heat dissipation and sealing.
