Variable piston pump
變量柱塞泵的壓力油經(jīng)泵體、泵殼變量殼體中的通油孔通過單向閥進(jìn)入變量殼體的下腔，當(dāng)拉桿向下運(yùn)動(dòng)時(shí)，推動(dòng)伺服活塞向下移動(dòng)，伺服閥的上閥口打開，變量殼體下腔的壓力油經(jīng)變量活塞中的通油孔進(jìn)入變量殼體上腔，由于上腔面積大于下腔，液壓力推動(dòng)活塞向下運(yùn)動(dòng)，帶動(dòng)銷軸使變量頭繞鋼球中心旋轉(zhuǎn)，改變變量頭的傾斜角（增大），柱塞泵的流量隨之增大。反之拉桿向上運(yùn)動(dòng)，變量頭的傾斜角向相反方向變化，泵的流量也隨之變化。當(dāng)傾斜角度變至零以后，則變量頭向負(fù)偏角方向變化，液流生產(chǎn)換向，泵的進(jìn)出油口變換。

主要特點(diǎn)：KS.Features

變量柱塞泵有軸向變量柱塞泵和徑向變量柱塞泵兩種。

現(xiàn)以軸向變量柱塞泵為例來說明其工作原理：

當(dāng)電動(dòng)機(jī)帶動(dòng)傳動(dòng)軸旋轉(zhuǎn)時(shí)，泵缸與柱塞一同旋轉(zhuǎn)，柱塞頭與斜盤保持接觸，斜盤與缸體成一角度，斜盤不轉(zhuǎn)。當(dāng)缸體旋轉(zhuǎn)時(shí)，由于斜盤的斜面作用，柱塞就會(huì)在泵缸中做往復(fù)運(yùn)動(dòng)。當(dāng)柱塞轉(zhuǎn)到斜盤低點(diǎn)，柱塞缸容積逐漸增大，因此液體經(jīng)配油盤的吸油口吸人油缸；而當(dāng)柱塞轉(zhuǎn)到斜盤高點(diǎn)，柱塞缸容積逐漸減小，油缸內(nèi)液體經(jīng)配油盤的出口排出液體。只要傳動(dòng)軸不斷旋轉(zhuǎn)，液體就會(huì)不斷地被吸入和排出。

改變斜盤的角度，就可以改變柱塞在泵缸內(nèi)的行程長(zhǎng)度，即可改變泵的流量。傾斜角度固定的稱為定量泵，傾斜角度可以改變的便稱為變量泵。

Germany KAYSEN Kaisen import variable piston pump overview
Variable piston pump pressure oil by the pump, the pump shell variable shell through the check valve through the check valve into the variable shell of the lower chamber, when the rod down movement, push the servo piston down, the servo valve The upper valve chamber is open, the variable pressure chamber of the variable shell is controlled by the variable oil hole into the variable cavity of the variable piston. As the upper cavity area is larger than the lower chamber, the hydraulic pressure drives the piston downward movement and drives the pin to make the variable head Rotate around the center of the ball to change the tilt angle of the variable head (increase), the piston pump flow increases. In contrast, the rod moves upward and the inclination angle of the variable head changes in the opposite direction, and the flow rate of the pump changes. When the tilt angle becomes zero, the variable head changes in the direction of the negative deflection, the flow is commutated, and the inlet and outlet of the pump are changed.

main feature:

Variable piston pump with axial variable piston pump and radial variable piston pump two.
Is the axial variable piston pump as an example to illustrate its working principle:
When the motor drives the drive shaft to rotate, the pump cylinder and the plunger with the rotation, the plunger head and the swash plate to keep in touch, swashplate and cylinder into an angle, swash plate does not turn. When the cylinder rotates, the plunger will reciprocate in the pump cylinder due to the ramp action of the swash plate. When the plunger to the slant plate low, the plunger cylinder volume gradually increased, so the liquid by the oil pan suction port suction cylinder; and when the plunger to the ramp high point, the plunger cylinder volume gradually reduced, The liquid in the cylinder is drained from the outlet of the oil pan. As long as the drive shaft continues to rotate, the liquid will be continuously inhaled and discharged.
Change the angle of the swashplate, you can change the plunger in the pump cylinder stroke length, you can change the pump flow. Tilt angle fixed called quantitative pump, tilt angle can be changed as a variable pump.

Key Benefits:

● High rated pressure
● Compact structure
● High efficiency
● Convenient flow adjustment
main application:

● Hydraulic
● Construction machinery
● ship
● High pressure, high flow and flow need to adjust the occasion
