4月18日零时33分，王大桥附近昆明监狱旁湖南望城建筑公司工地上，一场与时间赛跑的深井救援开始了。经了解得知，工地的工人在深井边缘进行液压泵操作时，因液压泵压力过大，导致三名正在作业的工人坠入深井内，其中两名伤情较轻的工人已被其他工友救出，还有一名伤势较重的工人仍被困井下。 导至这场事故发生的原因是由于人员操作液压泵不当而引起的，这次事故也为机械操作人员提了一个醒，机械操作不容忽视，稍不注意则会引发大事故。让我们关注液压泵使用。 液压泵使用方法 液压主率效的统系要取决于液压泵的容积效率，当容积效率下降到72%时，就需要维修，更换轴承和老化的密封件，要更出超复修或换配合间隙的磨擦副，使其性能得到恢复。 1液压泵的供油形式 直轴斜盘式压为分泵塞柱力供油型的自吸油型两种。压力供大泵压液型油都采用有气压的油箱，也有液压泵油补有带身本分泵向液压泵进油口提供压力油的液型油吸自。压泵的自吸油能力很强，无需外力供油。 箱油压次启动机器后，必须等液压渍箱达后压气才能操作机械。如液压油箱的气担就时足不压任机器，会对液压泵内的与滑鞭造，象现脱拉成出会造成泵体内回程板与压板的非采。损磨常正用补油泵供油的柱塞泵，使用3000h后，操作对需日每员人柱塞泵检查1-2次，检查液压泵否是响声转运正常。如发现液压缸速度下降或闷该应就，时车对补油泵解体检查，检查叶轮边沿现伤刮有否是象，内齿轮泵间隙是否过大。 对于自吸油液，泵塞柱型压油箱内的油液不得低于油标下限够足持保要，数量的液压油。液压油的清洁度越的泵压液，高使用寿命越长。 2液压泵用轴承 柱塞泵最重轴是件部的要承，如果轴承出现游隙，则不能保部内泵压液证三对磨擦副的正常间隙，同时也会副擦磨各坏破的静液压支承油膜厚度，降低柱塞用使的承轴泵寿命。据液压泵制造厂提供的资料均平的承轴， 使用寿命为10000h，超过此换更要需就值新口。 轴的来下卸拆承，没有专业检测仪器是无法检测隙游的承轴出的，只能采用目测，如发现滚柱表变或痕划有面色，就必须更换。 在更应，时承轴换注意原轴承的英文字母和型号，柱都大承轴泵塞采用大载荷容量轴承，{zh0}购买原格规原，家厂的产品，如果更换另一种品牌，应有承轴对教请经验的人员查表对换，目的是保持等度精的承轴级和载荷容量。

At 0:33 on the April 18, King Bridge near the city of Kunming, Wang Hunan Province next to the prison construction company on site, in a race against time to rescue the well started. The understanding that the site was the edge of the workers in deep pump operation due to excessive hydraulic pressure, resulting in three workers are operating deep inside the fall, including two minor injuries to workers have been rescued by other workers , and one seriously injured workers still trapped underground. Lead to this accident was due to workers caused by improper operation of hydraulic pump, the incident also provided a machine operator woke up, machine operation can not be ignored, little carelessness will lead to big accidents. Hydraulic pump used to our attention. Hydraulic Pump Use The main rate of hydraulic system efficiency hydraulic pump system depends on the volumetric efficiency, when the volume dropped to 72% efficiency, the need to repair, replace bearings and seals of aging, rehabilitation, or to be more trade surplus with the clearance of friction for the Deputy so that performance is restored. A hydraulic pump in the oil form Swashplate pressure axis column for the slave cylinder power plug from the oil-based oil absorption two kinds. Pressure for high-pressure liquid-type oil pump with pressure tank are used, but also body pump the oil up there with the wheel cylinder to the pump inlet to provide pressure oil from the liquid-type oil absorption. Oil absorption capacity of the pump pressure from the strong, no external oil supply. Box hydraulic time you start the machine, you must box up such stains after hydraulic compressed air to operate machinery. Hydraulic tank of gas, such as when the foot does not fear pressure on any machine, will pump and slip inside the whip made, as is pulling off the body into the pump will cause a return plate and the plate's non-mining. Damage often is used grinding up the piston oil pump, use 3000h, the operation on every member of one piston need to check on 1-2 times, check whether it is the noise transfer pump normal. Found to decrease the speed of hydraulic cylinder or nausea that should, when cars pump up the disintegration of the check, check the impeller has the edge now is like a scratch injury, internal gear pump gap is too large. For the self-absorbing liquid, pump plug cylindrical pressure oil within the tank shall not be less than the minimum standard enough oil to ensure adequate support, the number of hydraulic oil. Cleanliness of hydraulic oil pressure pump more liquid, the longer the high life. 2 hydraulic pump bearings Pump shaft is the most important pieces to the Department of commitment, if the clearance in bearing, the Department can not pump fluid within the three pairs of friction permits the normal clearance deputy, but also the bad break ground Vice wipe the hydrostatic bearing oil film thickness reduce the axial plunger pump used to make life commitments. According to information provided by pump manufacturers are flat bearing axis, life is 10000h, over this change must be on the threshold of a new port. Axis to demolition contractors under the unloading, there is no professional test equipment can not detect gap axis out of travel commitments, but to use visual, such as found in the table changes roller or mark designated on his face, we must change. In should be, when the bearing shaft bearings for attention to the letters and the original model, columns have a large bearing axial pump with large load capacity bearing plug, the best rules of the original purchase of the original cell, home plant products, if the replacement of another brand should have bearing axis of the teaching staff, please look-up table of the exchange of experience, the purpose is to maintain the fine degree of commitments such as axis-and load capacity.
