The Denison axial piston pump utilizes longevity and is associated with normal maintenance and care, the number and quality of hydraulic fluids, and fluid cleanliness. It is also a useful way to extend the life of the Denison axial piston pump by stopping the particles in the oil from causing wear on the piston pump friction pair.
Mason, product maintenance engineer of A&S Hydraulic Co., Ltd., advises that the replacement of parts in maintenance should be as convenient as possible with the original parts. Although these parts are more expensive than other counterfeit parts, the quality and stability are better. The purchase of self-made counterfeit parts at a price can save money in the short term, but it brings hidden dangers and is probably more harmful to the use of Denison axial piston pumps.
The Denison axial piston pump that receives the oil supply from the charge pump, after 3000 hours, the operator needs to check the Denison axial piston pump 1-2 times a day to check whether the sound of the hydraulic pump is normal. If the speed of the hydraulic cylinder is dropped or smoldering, the charge pump should be checked for damage, and if there is any scratch on the edge of the impeller, the internal gear pump gap is too large. For the self-priming oil type plunger pump, the oil in the hydraulic oil tank should not be lower than the lower limit of the oil mark, and a sufficient number of target hydraulic oils should be connected. The higher the cleanliness of the hydraulic fluid, the longer the service life of the hydraulic pump.
The most stressful part of the Denison axial piston pump is the bearing. If there is clearance in the bearing, the normal clearance of the three pairs of friction pairs inside the hydraulic pump can not be covered, and the thickness of the hydrostatic bearing oil film of each friction pair is also pulverized. The service life of the piston pump bearing. According to the information provided by the hydraulic pump manufacturer, the uniform service life of the bearing is 10000h. If this value is exceeded, it is necessary to exchange the new port. The disassembled bearing can not detect the clearance of the bearing without professional testing equipment, and can only accept visual inspection. If the roller of the invention is scratched or discolored, it must be exchanged.
When replacing the bearing, the original ink bearing and model of the original bearing should be meticulous. Most of the piston pump bearings accept large load capacity bearings. It is best to purchase the original manufacturer, the original specification of the product. If you exchange another brand, you should ask for the bearing. The staff of the resume is checked against the table, and the goal is to link the precision grade and load capacity of the bearing.
The Denison axial piston pump can also be used to save energy. The Denison axial piston pump is used in the actual production process, and the pressure or flow is usually used to adjust the situation. When the actual pressure is greater than the necessary pressure, it is adjusted by the overflow valve, so that the pressure of the matter is firmly connected and the overflow valve is applied to the overriding department. The motor is constantly running at full speed and the power consumption is stable.
The distribution plate has two situations: plane distribution and spherical distribution. The friction pair of the spherical surface distribution is repaired by the grinding force when the scratching surface of the cylinder body is shallower than the shallow force; when the groove of the cylinder body distribution surface is deep, the groove should be filled with the “appearance engineering skill” to hold the groove. Grinding, no blind grinding, to prevent the copper layer from thinning or oil leakage out of the steel base.
When receiving the overflow to regulate the pressure and flow, the surplus of the department overflows back to the original system, resulting in the piston pump having no diligence rate, and the obedience is low. If the Chuangjie energy-saving inverter is used, the relief valve can be set. It is closed, through the energy-saving inverter itself to actively mediate the pressure of things, link the pressure of the situation, and actively track the pressure of equipment deployment. Enables active control to save energy. The biggest advantage of this treatment method is that it can lower the operating energy consumption of the Denison axial piston pump, and the power saving result can reach more than 30%.
