due to currently injection molding equipment in liquid pressure types type relatively more, type type also rate, speed, pressure, amount, metal and other factors effect/influence, make liquid pressure selection comparison complex. generally low pressure can using/adopting HL油, for/regarding in, high pressure selection HM油.

    liquid pressure lubricated property (resistant abrasion property) for large type decrease abrasion 效果顺序 is sheet/slice 泵＞柱塞泵＞ gears 泵. sheet/slice is 主油泵 liquid pressure system tube/pipe its pressure large small selection HM油 is good, is sheet/slice 泵 叶 sheet/slice and 定子间 接触 and 运动形式极 easy abrasion loss, its for 钢 摩 scratch material most use high zinc HM resistant abrasion liquid pressure 油.

    for/regarding low pressure 柱塞泵 can use HM油 and HL油, high pressure 柱塞泵 use zinc HM油但 is 当柱塞泵 in has copper and 镀银部 parts 时, high zinc resistant abrasion agent generate abrasion loss, this type of 柱塞泵 need selection or low zinc resistant abrasion liquid pressure 油.

    for/regarding gears 泵, using/adopting HH, HL, HM油均 can, is high property can gears using/adopting HM油. for/regarding combined system sheet/slice and other combined, 应以叶 sheet/slice is selection, other is 柱塞泵时, 选 油 also by 柱塞泵 接受.

    comprehensive 起, usually HL油 can excellent used for toward 柱塞泵, suitable for sheet/slice 泵, high zinc HM油 suitable for type sheet/slice 泵. 无灰HM油 suitable for has copper and parts toward 柱塞泵, suitable for in low pressure sheet/slice 泵, is used for high pressure sheet/slice 泵. low zinc HM油则 suitable scope/range relatively wide, suitable for in, high pressure sheet/slice 泵, suitable for has copper and copper parts 柱塞泵.

    combined selection liquid pressure liquid is liquid pressure equipment positive as 起点, in system process in, and testing liquid pressure liquid property can 变化, ensure and to 予恰当 维护, long liquid pressure liquid and system, parts use lifespan, 避免因工 as 介质引起 system fault/failure, 甚至发生事故.

    liquid pressure use lifespan (即换油期)因 liquid pressure product types selection, as ring and system 运行工况 different, has relatively large 差异, 当选油 combined 理, product quality excellent 良, for liquid pressure system and liquid pressure liquid tool good and tube/pipe 理, 则换油期 can large large long.
