During the assembly and installation of hydraulic systems, the first concern is to provide easy access to the components and assemblies.\u00a0 The service replacement of a system component should not require disassembling of neighboring components and hydraulic drive components.\u00a0 Hydraulic systems should also not bear the weight of connecting pipes.\u00a0 Additionally, loads caused by elastic deformation are undesirable and lead to future maintenance problems and should be avoided.<\/p>\n
Sufficient pressure of hydraulic fluid should be provided in the hydraulic suction line.\u00a0 The diameter of the suction line should not be less than the mean diameter of the pump\u2019s suction inlet pipe.\u00a0 The flow rate of the fluid in the suction line should also be limited to approximately 1.2 meters per second.\u00a0 The resistance should be minimal with pressure in a range of between 0.02 \u2013 0.025 MPa.\u00a0 The rate of fluid flow in the drain lines of hydraulic drives with open circulation, should not exceed the flow rate in the suction line.\u00a0 Otherwise, air and oil emulsion will form in the hydraulic tank when being drained.\u00a0 The drain outlet should be submerged in the oil at a 45 degree angle.\u00a0 The minimum clearance of the outlet from the bottom of the tank is calculated as twice the diameter of the drain pipe.<\/p>\n
To prevent formation of air pockets, the drain outlets of hydraulic machines should be oriented in an upward direction.\u00a0 If the drain line is long, its cross section should be increased to prevent pressure build up in the machine.<\/p>\n
Connections are made by either flexible steel lines or rubber-metal hoses.\u00a0 The specifications of the lines or hoses should meet the following requirements:<\/p>\n
Air removal devices are installed in the topmost point of the pipes.<\/p>\n
Assembly is begun by testing all components and parts ensuring that all required parts are present and on hand.\u00a0 The first parts to be assembled are hydraulic assemblies, connection lines and instrumentation.\u00a0 Control and cooling systems are next in the assembly process.\u00a0 During assembly, all openings for the entry and exit of hydraulic fluids must be tightly sealed with plugs.\u00a0 Purification and etching of internal surfaces of the pipes is mandatory.\u00a0 Following the purification and etching process, the pipes are rinsed in special baths, dried with hot air and plugged until installation.\u00a0 To ensure pipe integrity and performance at high pressure, they are tested before installation using twice the normal operating pressure.<\/p>\n
The correct installation of sealing materials requires additional attention.\u00a0 Dents, chips and other damage on the surface of parts for connecting and sealing is unacceptable and will lead to fluids leaks.\u00a0 The size and cleanliness of contacting surfaces must comply with the existing standards and regulations.<\/p>\n
Before installing the seals, a lint-free swab, soaked in benzene, is used to treat the seal surfaces and the surfaces they will make contact with.\u00a0 Next, the surfaces are dried at room temperature until the benzene evaporates.\u00a0 Only then can the seals and part surfaces be coated with the operating liquid or a lubricating material neutral to the material of the seal.<\/p>\n
Seals must not be warped, stretched, twisted or damaged in any way.\u00a0 If the sealed components do not have bevels, special assembly arbors are used for installation of seals with uneven or step-shaped parts.<\/p>\n
Assembly and dis-assembly of positive displacement hydraulic drives must be done in accordance with the operators manual.<\/p>\n
Upon completion of assembly, hydraulic fluid will be placed into the equipment.\u00a0 Special attention must\u00a0 be paid as to the correct type and correct amount of hydraulic fluid that will be put into the system.\u00a0 The fluid must not contain water and solid particles must be removed by special filtration equipment prior to filling.<\/p>\n
GlobeCore<\/em><\/strong> offers the UVR line of equipment for this purpose and it is based on unique and industry leading technology.\u00a0 The GlobeCore<\/em> <\/strong>UVR system is equipped with drying and degassing sections. Solved gases and water are removed from the oil by vacuum and the liquid is filtered.\u00a0 The remaining contaminants are removed by Fuller’s Earth adsorbents.<\/p>\n The advantage of GlobeCore\u2019s<\/em><\/strong> equipment is its versatility.\u00a0 The UVR systems not only process hydraulic oils, they also process transformer oil, turbine oil, industrial oils, diesel fuel, HFO, kerosene, gas condensate and gasoline.<\/p>\n After using the GlobeCore Process<\/strong> <\/em>of oil purification, the hydraulic oil is fully restored and is made to comply with and\/or exceed industry standards.\u00a0 After using the GlobeCore Process<\/strong><\/em>, your company can confidently avoid the cost of repairs and replacement of components that would have most likely failed due contaminated hydraulic fluid.<\/p>\n Filtration fineness cannot\u00a0 exceed that of the finest filter in the hydraulic system.\u00a0 Hydraulic fluid is filled into the system at special filling stations equipped with manual or mechanical drives.\u00a0 The use of such stations have several obvious advantages.\u00a0 (1) Availability of a tank protecting the oil from contamination during transportation, storage and filling;\u00a0 and (2)\u00a0 input and output fine filters providing the required fineness of filtration.<\/p>\n Filling of a positive displacement hydraulic system can be roughly divided into three stages: (1) The first stage is to fill the oil into the hydraulic system and remove air through the drain system.\u00a0 The fluid is fed through the assembly line and into the lower drain point of the hydraulic drive.\u00a0 As liquid enters the system, air is pushed out into the hydraulic tank through the top drain point;\u00a0 (2) The hydraulic tank is filled to the top level; and (3) the hydraulic system is then topped off with fluid.<\/p>\n After completion of the these three stages, the positive displacement hydraulic drive is tested at idle with minimal rotation speed of the drive shaft.\u00a0 The tests are repeated every 15 seconds. Hydraulic system filling is controlled by the rate of decrease in the hydraulic tank fluid level.\u00a0 When the tank is filled, the drive motor is starts to operate at idle speed.\u00a0 It operates at this speed for 3 to 5 minutes.\u00a0 The system is then filled with liquid to the required level usually indicated by the mark on the hydraulic tank indicator.<\/p>\n","protected":false},"excerpt":{"rendered":" Hydraulic System Installation Requirements During the assembly and installation of hydraulic systems, the first concern is to provide easy access to the components and assemblies.\u00a0 The service replacement of a system component should not require disassembling of neighboring components and hydraulic drive components.\u00a0 Hydraulic systems should also not bear the weight of connecting pipes.\u00a0 Additionally,Read More <\/a><\/p>\n","protected":false},"author":24,"featured_media":1572,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[113],"tags":[128,43,129,130,131],"class_list":["post-1407","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-purificacion-de-fluido-hidraulico-casos-de-uso","tag-assembly","tag-hydraulic-system","tag-hydraulic-system-with-fluid","tag-installation-of-hydraulic-machines","tag-installation-requirements"],"acf":[],"language":"en","_links":{"self":[{"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/posts\/1407","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/comments?post=1407"}],"version-history":[{"count":0,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/posts\/1407\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/"}],"wp:attachment":[{"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/media?parent=1407"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/categories?post=1407"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aceite.globecore.com\/en\/wp-json\/wp\/v2\/tags?post=1407"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
