攪拌車液壓系統的兩種類型介紹

來源:http://www.oamenibuni.com/ 時間:2021-05-25

攪拌車的液壓系統通常分兩大類:開式系統與閉式系統,當前市場的品牌以開式系統為主,大方量攪拌車以閉式系統為主,結構緊湊,可靠性高,下邊對兩種結構進行詳解,教你如何識別:
The hydraulic system of the mixer is usually divided into two categories: open system and closed system. The current market brand is mainly open system, and the large quantity mixer is mainly closed system, with compact structure and high reliability. The following two structures are explained in detail to teach you how to identify them

兩個定量齒輪泵4、5。在低速狀態,液壓泵4向液壓馬達13供油;高速狀態,油泵4、5同時向液壓馬達13供油。液壓泵4、5的排油量是不同的,主要根據高速與低速供油狀態的轉速而定。換向閥8控制攪拌筒正反轉,溢流閥7起過載保護作用。溢流閥9、12與單向閥10、11起著防沖擊的補油保護作

Two fixed displacement gear pumps 4, 5. At low speed, the hydraulic pump 4 supplies oil to the hydraulic motor 13; At high speed, oil pumps 4 and 5 supply oil to hydraulic motor 13 at the same time. The oil displacement of hydraulic pumps 4 and 5 is different, mainly depending on the speed of high-speed and low-speed oil supply state. The reversing valve 8 controls the forward and reverse rotation of the mixing drum, and the overflow valve 7 plays the role of overload protection. Relief valves 9 and 12 and check valves 10 and 11 play the role of anti impact oil supplement protection.
伺服液壓缸2控制柱塞變量泵斜盤的方向與傾角,用來調節柱塞泵3的方向與排量。高壓溢流閥12能防止系統過載,起保護作用。兩個高壓溢流閥的開啟壓力值可根據液壓馬達兩側油路的負載分別調定,以適應不同工況的要求。
Servo cylinder 2 controls the direction and inclination of the swash plate of the piston variable displacement pump, which is used to adjust the direction and displacement of the piston pump 3. The high pressure relief valve 12 can prevent the system from overload and play a protective role. The opening pressure of the two high pressure relief valves can be adjusted according to the load of the oil circuit on both sides of the hydraulic motor to meet the requirements of different working conditions.
特點

通過發動機的油門來調節轉速,能耗大、不經濟。需要大油箱,結構龐大;液壓油中易混入空氣,振動與噪聲大,可靠性差、壽命短。
Adjusting the speed through the throttle of the engine consumes a lot of energy and is not economical. Large fuel tank and huge structure are needed; The hydraulic oil is easy to mix with air, and has high vibration and noise, poor reliability and short service life.
通過柱塞變量泵斜盤調整轉速、轉向,結構緊湊,油箱容積小,散熱要求高,工作穩定,可靠性高、壽命長。
By adjusting the speed and steering through the swashplate of the piston variable displacement pump, the structure is compact, the volume of the oil tank is small, the heat dissipation requirement is high, the work is stable, the reliability is high, and the service life is long.
