閘門液壓?jiǎn)㈤]機(jī)是指利用液體的壓力能來傳遞能量,從而控制閘門的開啟或關(guān)閉的一種啟閉機(jī)。它包括液壓傳動(dòng)系統(tǒng)和電氣控制系統(tǒng)。由液壓泵組、液壓閥組、液壓缸、油箱及附件、電氣柜及操作臺(tái)等五部分組成。
Hydraulic gate opening and closing machine refers to a type of opening and closing machine that uses the pressure energy of liquid to transmit energy and control the opening or closing of gates. It includes hydraulic transmission system and electrical control system. It consists of five parts: hydraulic pump group, hydraulic valve group, hydraulic cylinder, oil tank and accessories, electrical cabinet and operation console.
其工作原理是:液壓泵把原動(dòng)機(jī)輸出的機(jī)械能變?yōu)橐后w壓力能,經(jīng)過油管道及液壓閥進(jìn)入液壓缸,通過液壓缸及活塞桿把液體的壓力能轉(zhuǎn)變?yōu)楣ぷ鳈C(jī)的機(jī)械能,從而驅(qū)使閘門完成開啟或關(guān)閉等動(dòng)作。
The working principle is that the hydraulic pump converts the mechanical energy output by the prime mover into hydraulic pressure energy, which enters the hydraulic cylinder through the oil pipeline and hydraulic valve. The hydraulic cylinder and piston rod convert the hydraulic pressure energy into the mechanical energy of the working machine, thereby driving the gate to complete actions such as opening or closing.
LQ型螺桿啟閉機(jī)是閘門(堰門、閥門)等的上下運(yùn)動(dòng)或旋轉(zhuǎn)堰門運(yùn)動(dòng)(旋轉(zhuǎn)堰門的水位調(diào)節(jié)、閥門90度旋轉(zhuǎn)開啟與閉合)的執(zhí)行機(jī)構(gòu)。其結(jié)構(gòu)緊湊合理,運(yùn)動(dòng)穩(wěn)定穩(wěn)定,安全侃侃裝置靈敏可靠,且外形美觀,性價(jià)比高。
The LQ type screw hoist is an actuator for the up and down movement or rotating movement of gates (gates, valves), etc. (water level regulation of rotating gates, opening and closing of valves by 90 degrees rotation). Its structure is compact and reasonable, the movement is stable and stable, the safety and communication device is sensitive and reliable, and the appearance is beautiful with high cost-effectiveness.
螺桿啟閉機(jī)按支力源分為手動(dòng)啟閉機(jī)和電動(dòng)啟閉機(jī)(LQD);按吊點(diǎn)數(shù)量分為單吊點(diǎn)數(shù)量分為單吊點(diǎn)和雙吊點(diǎn);按螺桿啟閉機(jī)型式分為明桿式和暗桿式兩種;手動(dòng)啟閉機(jī)又分為手輪啟閉機(jī)(LQS)、側(cè)搖啟閉機(jī)(LQC)和封閉平把啟閉要(LQPBO)。
Screw opening and closing machines are divided into manual opening and closing machines and electric opening and closing machines (LQD) according to the supporting force source; According to the number of lifting points, it can be divided into single lifting points and double lifting points; According to the type of screw opening and closing machine, there are two types: visible rod type and hidden rod type; Manual opening and closing machines are divided into handwheel opening and closing machines (LQS), side swing opening and closing machines (LQC), and closed handle opening and closing machines (LQPBO).
明桿式啟閉機(jī)是依靠啟閉機(jī)螺母的旋轉(zhuǎn),使螺桿升降,從而帶動(dòng)閘桿升降,實(shí)現(xiàn)閘門的開啟和關(guān)閉,暗桿式啟閉機(jī)是依靠啟閉機(jī)螺母的旋轉(zhuǎn),從而使安裝在閘板上或吊桿上的螺母帶動(dòng)閘門的升降,實(shí)現(xiàn)閘門的開啟和關(guān)閉。
The open rod hoist relies on the rotation of the hoist nut to lift the screw, thereby driving the gate rod to lift and open the gate. The concealed rod hoist relies on the rotation of the hoist nut to drive the gate installed on the gate or suspension rod to lift and open the gate.
