        泵浦 is has pressure system “心脏”. therefore in 任何时候, pressure system issues, large 家都会 issues 归咎于泵浦 upper.

        事实 upper, 就泵浦 loss bad causes 而言, is 泵浦本身缺失 引起 phenomenon is very less to. more positive 确 说, 当泵浦 工 as day 渐恶化, 便显示出 in pressure system in, already 经隐藏著 its it issues types 征候.

        泵浦 loss bad in separation 之九十至九十五, can large 致 归 nano lower types causes:

        一, gas mixed 入(Aeration) 

        空 gas mixed 入, 系指一 types bubbles in system liquid pressure in dispersion phenomenon. 当油路 system in has by pressure shrink bubbles 面临泵浦 export pressure 时, 便会发生 this type of 破裂效应. this type of 破裂效应会造 formed internal pressure sheet/plate, wear resistant sheet/plate and other 靠近此破裂点 metal surface phenomenon, 并导致该处 generate degree high temperature.

        空 gas mixed phenomenon, 泵浦会 generate 霹雳啪啦 巨 large 噪音. this type of 噪音 音调会随著 pressure rise high rise high, degree gas mixed phenomenon 会导致 liquid pressure emulsification (因空 gas in has a large amount of water gas). but also, more due to liquid pressure in gas pressure shrink phenomenon, 引起各部油 pressure parts as 不顺畅 and other issues.

        导致空 gas mixed 入泵浦 in can can is:

        1, defect 轴封.

        2, 油箱至泵浦入口部 separation combined 处泄漏.

        3, 油面太 low or 者返回油箱之回油 tube/pipe by in upper, formed inner liquid pressure generate bubbles, in 尚未消 remove its bubbles by again 次吸入.

        二, 空蚀(Cavitation) 

        空蚀, 系指当 pressure decrease low to saturated and gas pressure lower in liquid pressure 油之流体 in 发生 一 types local gas phenomenon. more simple 说, liquid pressure has full 充满应该占 has 空间时, is in has true 空情况发生, 便会引起 this type of phenomenon.

        空蚀 引起 噪音 and gas mixed phenomenon 引起之噪音 large similar. formed phenomenon factors has:

        1, and electrical 动马达匹配 issues, formed 泵浦转 speed high.

        2, long 泵浦吸入 tube/pipe 路, or is 吸入口受限.

        3, liquid pressure 油之黏 degree high.

        4, upper gas is 否塞住.

        5检查泵浦吸入口之 滤网.

        三, 污染(Contamination) 

        存 in pressure system in 任何异 material, for/regarding pressure parts and its efficiency 而言, has defect effect/influence. 污染 异 material has can can is solid 体, liquid or is gas 体.

         large separation material 污染, 都会造 formed parts and parts 紧密 余隙间引起摩 scratch 运动, this will 导致工 parts accelerated abrasion loss and loss.

        油路 in 污染源 large can separation is:

        1, parts 油缸, block, internal, tube/pipe 路接头 and other.

        2, or O-ring脆化 fracture.

        3, liquid pressure long time high temperature lower 变质, generate 油污.

        4, 泵浦因空 gas mixed or 空蚀造 formed metal surface material 质.

        四, hot (Excessive heat) 

         hot, ultra- 规定之 upper temperature degree, 而引起流体黏 degree 改变 一 types hot phenomenon. hot will formed liquid pressure accelerated oxidation and make liquid pressure degree 恶化, formed reaction, therefore hot true positive causes must add troubleshooting, make has will issues more positive.

        导致 hot causes is:

        1, negative 荷运转, ultra- pressure use.

        2, gas mixed and phenomenon formed.

        3, 油污染造 formed.

        五, ultra- pressure (Over-pressurization) 

         ultra- pressure 系指操 as pressure large 于泵浦 design pressure. ultra- pressure make internal parts to large force amount 并引起 internal parts loss bad.

        述之 causes 都会留 lower it has loss bad 迹象. 就辨认 and understanding this belt/tape versus important. according to this type of methods, can in 另一 泵浦尚未 loss bad front, will true positive 引起泵浦 loss bad causes add positive.
