  二手叉車配送機制主要部分:

  The main parts of  used forklift truck distribution mechanism are as follows:
  二手關節叉車閥:閥門分為閥和排氣閥兩種類型,其作用是開啟和關閉進氣、排氣通道,它由頭部和桿件組成。閥頭用于開啟和關閉進排氣通道,閥桿用于引導閥門的運動。進氣閥采用普通合金鋼,排氣閥采用耐熱合金鋼,因為排氣閥頭部與燃氣直接接觸,受熱嚴重。
  Second-hand joint forklift valve: Valves are divided into two types: valve and exhaust valve. Its function is to open and close the intake and exhaust channels. It consists of head and rod. The valve head is used to open and close the intake and exhaust passages, and the stem is used to guide the movement of the valve. The intake valve is made of common alloy steel, and the exhaust valve is made of heat-resistant alloy steel. Because the head of the exhaust valve is directly in contact with the gas, it is heated seriously.
  為了保證閥頭與閥座之間的緊固配合和熱傳導,閥頭與閥座之間采用錐形連接面和地面。錐面與頂面夾角稱為閥錐角,常用的閥錐角為30°和45°。閥體是閥門運動的導向部件。在普通閥桿本體的尾部開槽,安裝錐形鎖板。
  In order to ensure the tight fit and heat conduction between the valve head and the seat, the conical connection surface and the ground are used between the valve head and the seat. The angle between the cone surface and the top surface is called the valve cone angle. The commonly used valve cone angle is 30 degrees and 45 degrees. The valve body is the guiding part of the valve movement. The tail of the ordinary stem body is grooved and the conical locking plate is installed.
  2、二手直升機叉車閥座:閥座是缸體(側閥)或閥蓋(頂閥),直接加工出圓形閥座孔,它具有與閥門密封作用。有些閥座可以加工成耐磨合金鑄鐵環,嵌入缸體或缸蓋內。
  2. Second-hand helicopter forklift seat: The seat is cylinder block (side valve) or valve cover (top valve), which directly processes the circular seat hole, which has the function of sealing with the valve. Some seats can be machined into wear-resistant alloy cast iron rings and embedded in cylinder blocks or cylinder heads.
  3、二手heli叉車閥導管:其作用是引導閥門做出正確的軸向運動,同時也間接地將閥桿的熱量傳遞到水套上。為了便于維修和更換,閥門管道被單獨制造并壓入缸體(或缸蓋)。當閥管被壓入缸體(或缸蓋)時,應有一定的干涉和壓力深度,以保證良好的傳熱。
  3. Used Heli forklift valve conduit: Its function is to guide the valve to make correct axial motion, but also indirectly transfer the heat of the valve stem to the water jacket. In order to facilitate maintenance and replacement, valve piping is manufactured separately and pressed into the cylinder (or cylinder head). When the valve tube is pressed into the cylinder (or cylinder head), there should be a certain degree of interference and pressure depth to ensure good heat transfer.
  4、二手heli叉車閥彈簧:其作用是保證閥門與閥座關閉,并減緩和克服由閥門等傳動部件產生的慣性力,以防止閥門分配機構的正常工作。
  4. Used Heli forklift valve spring: Its function is to ensure the closure of valve and seat, and to reduce and overcome inertia force generated by transmission parts such as valves, in order to prevent the normal operation of valve distribution mechanism.
  5、二手直升機叉車氣門挺桿:將凸輪運動推到氣門(側式)或推桿(頂式)上,控制氣門的啟閉。
  5. Valve tappet of second-hand helicopter forklift truck: Push cam motion to valve (side type) or push rod (top type) to control valve opening and closing.

  6. 二手直升機叉車閥推桿:將挺桿的運動轉移到頂置閥機構的搖臂上。推桿是由空心鋼管制成的直桿,兩端焊接成不同形狀。上端為凹球,搖臂調節螺釘的球頭位于凹球內。下端為圓球頭,用于插入挺桿的凹球支承。
  6. Second-hand helicopter forklift valve push rod: transfer the movement of the tappet to the rocker arm of the overhead valve mechanism. Push rod is a straight rod made of hollow steel tube and welded into different shapes at both ends. The upper end is a concave ball, and the ball head of the rocker arm adjusting screw is located in the concave ball. The lower end is a spherical head, which is used to insert concave ball support of tappet.
  7. 二手直升機叉車氣門搖臂:其作用是改變挺桿向氣門運動的方向。它是一個不等的臂桿,中間有一個圓孔。長臂的末端有一個與閥門尾部接觸的圓形彎曲工作面。短臂末端設有螺釘孔,用于安裝調節螺釘和鎖緊螺母,以調節閥門間隙。中間部分為帶有青銅襯套的搖臂軸承。
  7. Valve rocker arm of second-hand helicopter forklift truck: Its function is to change the direction of the tappet to the valve. It is an unequal arm bar with a round hole in the middle. The end of the long arm has a circular bending working face in contact with the tail of the valve. The end of the short arm is provided with a screw hole for installing adjusting screw and locking nut to adjust valve clearance. The middle part is rocker bearing with bronze bushing.
  8、二手接頭叉車搖臂軸:它是一個空心的圓形軸,有幾個支架安裝在氣缸蓋上,搖臂臂部設置在搖臂軸上,并能使搖臂在軸上作圓周擺動。軸內孔與主油通道連接,為配油機構提供潤滑油。
  8. Second-hand joint forklift rocker arm axle: It is a hollow circular axle. Several brackets are installed on the cylinder head. The rocker arm is set on the rocker arm axle and can make the rocker arm swing around the axle. The inner hole of the shaft is connected with the main oil passage to provide lubricating oil for the oil distribution mechanism.
  9. 二手直升機叉車凸輪軸:用于控制各缸閥的關閉時間和開啟變化。并驅動油泵、油泵、分配器等配件。它由進氣凸輪、排氣凸輪、軸頸、驅動油泵和分配器的齒輪和驅動油泵搖臂的偏心輪組成。
  9. Second-hand helicopter forklift camshaft: used to control the closing time and opening changes of cylinder valves. And drive oil pump, oil pump, distributor and other accessories. It consists of intake cam, exhaust cam, journal, gear driving oil pump and distributor and eccentric wheel driving oil pump rocker arm.
  10、使用heli叉車正時齒輪:凸輪軸通常由曲軸通過一對正時齒輪驅動。小齒輪安裝在曲軸的前部,稱為曲軸正時齒輪。大齒輪安裝在凸輪軸的前部,稱為凸輪軸正時齒輪。齒輪比為2∶1,保證曲軸旋轉兩次,凸輪軸旋轉一次。
  10. Use Heli forklift timing gear: The camshaft is usually driven by a crankshaft through a pair of timing gears. The pinion is installed in the front of the crankshaft, which is called crankshaft timing gear. The big gear is installed in the front of the camshaft, which is called the camshaft timing gear. The gear ratio is 2:1, which ensures that the crankshaft rotates twice and the camshaft rotates once.
  為了保證正確的分配相位和發射時間,在兩個齒輪的對應位置上刻上網格標記。為了限制凸輪軸的軸向運動隨發動機轉速的變化,安裝了軸向限位裝置。
  In order to ensure the correct allocation of phase and launch time, grid marks are engraved on the corresponding positions of the two gears. In order to limit the change of camshaft axial motion with engine speed, an axial limit device is installed.
