柱塞泵的保养方法！

The maintenance method of the plunger pump!

柱塞泵是液压系统的一个重要装置，具有额定压力高，结构紧凑，效率高和流量调节方便等优点，被广泛应用于高压，大流量和流量需要调节的场合。在日常使用中，应对其进行适时地维护，方能使其发挥最佳功效。

The plunger pump is an important device of the hydraulic system. It has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. It is widely used in high pressure, large flow and flow needs to be adjusted. In daily use, it should be properly maintained to enable them to perform their best functions.

采用补油泵供油的柱塞泵，使用3000h后，操作人员每日需对柱塞泵检查1-2次，检查液压泵运转声响是否正常。如发现液压缸速度下降或闷车时，就应该对补油泵解体检查，检查叶轮边沿是否有刮伤现象，内齿轮泵间隙是否过大。对于自吸油型柱塞泵，液压油箱内的油液不得低于油标下限，要保持足够数量的液压油。液压油的清洁度越高，液压泵的使用寿命越长。

When the pump is supplied by the oil pump, the operator will check the plunger pump 1-2 times every day after using 3000h, and check whether the running sound of the hydraulic pump is normal. If it is found that the speed of the hydraulic cylinder drops or the car is stuffy, it is necessary to check the disintegration of the oil pump, check whether the edge of the impeller has scratches, and whether the clearance of the inner gear pump is too large. For self suction plunger pump, the oil in the hydraulic tank should not be lower than the lower limit of the oil standard, and enough quantity of hydraulic oil must be maintained. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.

柱塞泵最重要的部件是轴承，如果轴承出现游隙，则不能保证液压泵内部三对磨擦副的正常间隙，同时也会破坏各磨擦副的静液压支承油膜厚度，降低柱塞泵轴承的使用寿命。据液压泵制造厂提供的资料，轴承的平均使用寿命为10000h，超过此值就需要更换新口。拆卸下来的轴承，没有专业检测仪器是无法检测出轴承的游隙的，只能采用目测，如发现滚柱表面有划痕或变色，就必须更换。

The most important part of the plunger pump is the bearing. If the bearing appears in the clearance, it can not guarantee the normal clearance of the three pairs of friction pairs inside the hydraulic pump, and will also destroy the hydrostatic bearing oil film thickness of the friction pair and reduce the service life of the piston pump bearing. According to the data provided by the hydraulic pump manufacturer, the average service life of the bearing is 10000h. Disassembled bearings, no professional testing instruments are unable to detect the clearance of the bearings, only visual testing, such as found that the roller surface scratches or discoloration, it must be replaced.

在更换轴承时，应注意原轴承的英文字母和型号，柱塞泵轴承大都采用大载荷容量轴承，最好购买原厂家，原规格的产品，如果更换另一种品牌，应请教对轴承有经验的人员查表对换，目的是保持轴承的精度等级和载荷容量。

When replacing the bearing, we should pay attention to the English letter and model of the original bearing. Most of the piston pump bearings are bearing large load bearing. It is best to buy the original manufacturer and the original product. If the other brand is replaced, it should be asked to change the table with the experience of the bearing. The purpose is to hold the bearing precision grade and load capacity.

柱塞泵使用寿命的长短，与平时的维护保养，液压油的数量和质量，油液清洁度等有关。避免油液中的颗粒对柱塞泵磨擦副造成磨损等，也是延长柱塞泵寿命的有效途径。在维修中更换零件应尽量使用原厂生产的零件，这些零件有时比其它仿造的零件价格要贵，但质量及稳定性要好，如果购买售价便宜的仿造零件，短期内似乎是节省了费用，但由此出带来了隐患，也可能对柱塞泵的使用造成更大的危害。

The service life of plunger pump is related to normal maintenance, quantity and quality of hydraulic oil, cleanliness of oil and so on. It is also an effective way to prolong the service life of plunger pump by avoiding the wear of oil particles to the friction pairs of piston pump. Replacement parts should be used as far as possible in the maintenance of parts. These parts are sometimes more expensive than other counterfeit parts, but the quality and stability are better. If buying cheap counterfeit parts, it seems to save the cost in the short term, but it brings hidden dangers and may cause more use of the plunger pump. Great harm.

配流盘有平面配流和球面配流两种形式。球面配流的磨擦副，在缸体配流面划痕比较浅时，通过研磨手段修复;缸体配流面沟槽较深时，应先采用“表面工程技术”手段填平沟槽后，再进行研磨，不可盲目研磨，以防铜层变薄或漏油出钢基。

The port plate has two forms: the plane distribution and the spherical distribution. When the surface of the cylinder body is very shallow, the friction pair of spherical matching is repaired by grinding. When the groove of the cylinder body is deep, the surface engineering technique should be used first to fill the groove, and then be lapping again, not to be lapping blindly, in case the copper layer is thinner or the oil leaks out of the steel base.

以上是柱塞泵日常保养措施，合理有效的保养是延长其使用寿命的前提，也是提高企业生产效率的手段之一。

The above is the routine maintenance measures for plunger pumps. Reasonable and effective maintenance is the premise for prolonging their service life and is also one of the means to improve the production efficiency of enterprises.
