1. The residual oil sucked into the oil pump is reduced, and the engine oil residue adhered to the filter collector will increase with the increase of service time, resulting in a small cross-section of the oil removal channel, and the oil sucked into the automobile by the oil pump is reduced, resulting in a reduction in the oil pressure of the lubrication system, or even no working pressure.

2、装裁机机油滤芯应用过久后，被过虑出的机诫残渣集存有过滤芯上。伴随着10吨轮式挖掘机厂家使用时间增加，过滤芯表面总面积存的机械设备杂品质加大，阻塞润滑油流动性通道，导致润滑部位机油压力减少。

2. After the oil filter element of the cutting machine has been used for a long time, the filtered machine residues will be stored on the filter element. With the increase of the service time of the 10 ton wheel excavator manufacturers, the mechanical equipment impurities in the total surface area of the filter element increase, blocking the lubricating oil liquidity channel, resulting in the reduction of the oil pressure at the lubricating parts.

3、装裁机油泵可以造成的压力的基础原理是汽车机油在主油道内流动性有摩擦阻力，假如润滑系的主油道有泄漏，限压阀控制精度工作压力过低或关掉不紧，发动机曲轴或发动机凸轮轴颈等处因损坏相互配合空隙过大，都是会导致润滑系统软件的泄漏量加大，系统内的机油压力会伴随着泄漏量加大而相对应减少。

3. The basic principle of the pressure that can be caused by installing and cutting the oil pump is that the automobile oil has friction resistance in the main oil passage. If there is leakage in the main oil passage of the lubrication system, the control accuracy of the pressure limiting valve is too low or the pressure is not closed tightly, and the engine crankshaft or engine camshaft journal are damaged and have too large mutual coordination gap, the leakage of the lubrication system software will increase, The oil pressure in the system will decrease correspondingly with the increase of leakage.

4、装载机限压阀调节不合理，机油压力超出标准值时，便摆脱弹蓄的弹性将闸阀拉开使系统软件内放压，机油压力小于弹性时，闸阀在弹的效果下关掉，润滑系的机油压力在于弹暂弹力的大小。

4. The adjustment of the pressure limiting valve of small forklift loader is unreasonable. When the oil pressure exceeds the standard value, it will get rid of the elasticity of the spring storage and open the gate valve to release the pressure in the system software. When the oil pressure is less than the elasticity, the gate valve will be closed under the effect of the spring. The oil pressure of the lubrication system depends on the elasticity.

5、当运动粘度因气温过高或其它成分的稀释液而使黏度减少，造成润滑系泄漏量加大而工作压力减少。

5. When the kinematic viscosity decreases due to high temperature or diluents of other components, the leakage of the lubrication system increases and the working pressure decreases.

6、在工作中的情况下，油泵的蜗轮会出现一定的损坏，假如汽车机油内带有机械设备残渣的时候会快其损坏过程，当损坏后，二手小铲车装载机内部结构泄漏量加大，因此油阀效率随着相对应减少。

6. Under working conditions, the worm gear of the oil pump will be damaged to some extent. If the automobile oil contains mechanical equipment residues, the damage process will be accelerated. When it is damaged, the internal structure leakage of the second-hand small forklift loader will increase, so the oil valve efficiency will decrease correspondingly.

7、机油压力显示仪表包含机油压力表和机油压力感应器，是用于体现汽车发动机润滑系的机油压力尺寸。

7. The oil pressure display instrument consists of oil pressure gauge and oil pressure sensor, which is used to reflect the oil pressure of automobile engine lubrication system.

8、冷却塔的汽车机油管内腔黏附有机械设备杂物或胶原纤维，不但会导致汽车机油排热欠佳，与此同时也会使汽车机油的商品流通横截面减少，比较严重的时候会产生阻塞状况，进而造成润滑部位机油压力减少。

8. The internal cavity of the automobile oil pipe of the cooling tower is adhered with mechanical equipment sundries or collagen fibers, which will not only lead to poor heat removal of the automobile oil, but also reduce the cross-section of the commodity flow of the automobile oil. In serious cases, it will cause blockage, and then reduce the oil pressure at the lubricating parts.
