The pneumatic booster pump should keep enough hydraulic oil. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump. For the plunger pump supplied by make-up oil pump, the operator should check the plunger pump 1-2 times a day after it is used for 3000h to check whether the pump operates normally. If it is found that the speed of the hydraulic cylinder drops or the car is blocked, the make-up oil pump should be disassembled and checked to see if there is scratch on the edge of the impeller and whether the clearance of the internal gear pump is too large. For the self-priming plunger pump, the oil in the hydraulic oil tank shall not be lower than the lower limit of the oil standard, and the Haskel pneumatic booster pump shall keep enough hydraulic oil. The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.
The most important part of plunger pump is bearing. If the bearing clearance occurs, the normal clearance of three pairs of friction pairs in the hydraulic pump can not be guaranteed. At the same time, the thickness of hydrostatic support oil film of each friction pair will be damaged, and the service life of piston pump bearing will be reduced. According to the information provided by the hydraulic pump manufacturer, the average service life of the bearing is 10000h. If it exceeds this value, it needs to be replaced with a new one. The bearing clearance can not be detected without professional testing instruments. Only visual inspection can be used. If there is scratch or discoloration on the roller surface, it must be replaced.
In the replacement of bearings, attention should be paid to the English letters and models of the original bearings. Most of the bearings in plunger pumps are of large load capacity. It is better to purchase the products of the original manufacturers and specifications. If another brand is replaced, the experienced personnel should be consulted to check the table for replacement, so as to maintain the accuracy grade and load capacity of bearings.
The service life of Haskel pneumatic booster pump is related to the usual maintenance, the quantity and quality of hydraulic oil and the cleanliness of oil. It is also an effective way to prolong the service life of the piston pump to avoid the wear caused by the particles in the oil. When replacing parts in maintenance, we should try our best to use the parts produced by the original factory. These parts are sometimes more expensive than other imitation parts, but the quality and stability are better. If we buy the imitation parts with low price, it seems to save the cost in a short time, but it brings hidden dangers and may cause greater harm to the use of plunger pump.
The port plate has two forms: plane distribution and spherical distribution. When the scratch on the valve plate surface of the cylinder block is shallow, the friction pair of the spherical valve port shall be repaired by grinding; when the groove on the valve plate surface of the cylinder block is deep, the groove shall be filled with surface engineering technology, and then the grinding shall be carried out. Blind grinding is not allowed to prevent the copper layer from thinning or oil leakage and tapping the steel base.
