in the hydraulic system, power components - - - The types of hydraulic pump, hydraulic oil is the main object. Generally said, first of all, all kinds of pumps, determine the applicable range of viscosity, more specific varieties brand of hydraulic oil is determined. Injection molding machine is recommended to use anti-wear hydraulic oil. The temperature is lower in north China, can consider to use the hydraulic oil at low temperature.
the hydraulic oil as the working medium of hydraulic transmission, in addition to energy transfer, lubrication and protect metal from being corroded components movement parts of the role. Especially in the current hydraulic technology constantly to high pressure, integration, miniaturization, and the application of electronic technology, the hydraulic system working reliability, sensitivity, stability and life raised out the high probability of high requirement, therefore, should choose the good performance of injection molding machine hydraulic system, has the high cleanliness of hydraulic oil. Therefore, must understand the requirements of the hydraulic system for oil, reasonably choose, right in the maintenance of custody, to ensure the normal operation of hydraulic system, less out of order, improve production efficiency.
the current type of hydraulic pump in the injection molding equipment is more, and because of the same type pump power, speed, pressure, flow rate, metal material and so on factors, make the selection of hydraulic oil is more complex. Generally low pressure pump can be used in a oil HL, for medium and high pressure oil pump should be chosen HM.
the machine hydraulic system can work normally, in addition to the reasonable design of system and components manufacturing quality and maintain the use conditions, the hydraulic oil has applicability cleanliness is a very important factor. The lubricity of hydraulic oil of
( Abrasion resistance) For the three pump vane pump is antifriction effect sequence > > plunger pump gear pump. Vane pump as the main oil pump hydraulic system regardless of its size appropriate chooses HM oil pressure is good, because the vane pump vane and contact between the stator and the motion form of easy to wear and its steel on steel friction pair material best suited for use high zinc HM anti-wear hydraulic oil.
for low pressure plunger pump available HM oil and oil HL, high-pressure plunger pump with zinc HM oil but when plunger pump with bronze and silver plated parts, high anti-wear agent can produce zinc corrosion wear and tear, this kind of plunger pump to choose ash free or low zinc anti-wear hydraulic oil.
for gear pump, the use of HH, HL, HM, but high performance gear pump HM oil should be adopted. For composite systems such as vane pump and other pump combination, should be given priority to with vane pump selection, when other pump as the plunger pump, the selected oil should also be accepted by plunger pump.
together, usually the HL oil can be used in axial piston pump, but does not apply to vane pump, high zinc HM oil is suitable for all kinds of vane pump. Ash-free HM oil is suitable for containing copper and silver parts of axial piston pump, can also be applied to the low pressure vane pump, but it is not used in high-pressure vane pump. Low zinc HM oil has wide application scope, applies to medium, high-pressure vane pump, can also be applied to copper and copper parts of plunger pump.
for determination of the hydraulic oil pollution conditional case, the available various instrument testing of the hydraulic oil pollution degree; But at the scene of the production, often do not have a special instrument to test the level of hydraulic oil contaminated, most directly observed with the method of the see, nose to smell the hydraulic oil pollution. The average person in the eye of the visibility of 40 um, so, look very dirty oil has actually been pollution is more serious.
the reasonable selection of hydraulic oil is the starting point of the hydraulic equipment to work normally, only in the process of system operation, should test the performance of the hydraulic oil changed in time, ensure timely to give proper maintenance, in order to prolong the service life of hydraulic oil and systems, components, avoid system failure caused by working medium, or even an accident.
the service life of hydraulic oil ( The oil change period) For hydraulic oil varieties selection, work environment and system operation condition is different, and have bigger difference, as oil is reasonable, the product quality is good, the hydraulic system and hydraulic oil with good maintenance and management of the oil change period may be extended greatly.
the hydraulic oil pollution control measures of
filtering method of hydraulic system is the most fatal solid particle contamination, used for filtration apparatus is a good way to control and reduce the pollution, can guarantee the hydraulic oil pollution levels below the system components can withstand level. Note: even if is the new oil, also want to use after filtering.
