PARKER大后方液壓

大后方液壓依托PARKER強(qiáng)大的力量向國(guó)內(nèi)液壓行業(yè)領(lǐng)域提供的技術(shù)與服務(wù)，PARKER大后方液壓通過完善的技術(shù)核心在柱塞泵與電磁閥方面有非常深入的研究莉紊，通過PARKER的核心技術(shù)支持凿栅，大后方在PARKER柱塞泵領(lǐng)域服務(wù)范圍達(dá)到全國(guó)90多個(gè)城市地區(qū)。在今后的PARKER與大后方液壓的合作機(jī)會(huì)在不斷的加深自畔。

PARKER柱塞泵

PARKER柱塞泵根據(jù)傾斜元件的不同淘客，有斜盤式和斜軸式兩種。斜盤式是斜盤相對(duì)回轉(zhuǎn)的缸體有一傾斜角度杨匕，而引起柱塞在泵缸中往復(fù)運(yùn)動(dòng)着饥。傳動(dòng)軸軸線和缸體軸線是一致的。這種結(jié)構(gòu)較簡(jiǎn)單惰赋，轉(zhuǎn)速較高宰掉，但工作條件要求高，PARKER柱塞端部與斜盤的接觸部往往是薄弱環(huán)節(jié)赁濒。斜軸式的斜盤軸線與傳動(dòng)軸軸線是一致的轨奄。它是由于柱塞缸體相對(duì)傳動(dòng)軸傾斜一角度而使柱塞作往復(fù)運(yùn)動(dòng)。流量調(diào)節(jié)依靠擺動(dòng)柱塞缸體的角度來實(shí)現(xiàn)流部，故有的又稱擺缸式戚绕。它與斜盤式相比，工作可靠枝冀，流量大舞丛，但結(jié)構(gòu)復(fù)雜。大后方對(duì)PARKER柱塞泵產(chǎn)品特別執(zhí)著果漾，在液壓行業(yè)PARKER產(chǎn)品在大后方液壓算是重點(diǎn)銷售服務(wù)的產(chǎn)品球切，以致一直得到同行業(yè)的大力支持。

派克柱塞泵PAVC系列特性

1绒障、下行程時(shí)通過系統(tǒng)缸壓減少壓力峰值晃烟；`

2、在低系統(tǒng)壓力時(shí)场恬，也確保補(bǔ)償器功能翠柄，補(bǔ)償壓力<10 bar；

3吝寒、9個(gè)柱塞和新的予壓縮容積技術(shù)使流量脈動(dòng)降至

4皿完、剛性的和有限元優(yōu)化的泵體設(shè)計(jì)

5、補(bǔ)償器多樣化办煞；

6狈馏、100%額定扭矩的通軸驅(qū)動(dòng)；

7害恋、同樣尺寸和型號(hào)的泵的組合（多聯(lián)泵）缘说，安裝接口；

8、基本上是采用公制或SAE接口劣零。

派克柱塞泵PAVC系列控制方式

1钟助、標(biāo)準(zhǔn)型壓力補(bǔ)償變量控制器；

2掏秩、遙控型壓力補(bǔ)償變量控制器绘证；

3、負(fù)載傳感變量控制器哗讥；

4嚷那、雙閥負(fù)載傳感變量控制器；

5杆煞、恒功率補(bǔ)償變量控制器魏宽；

6、電液比例變量控制器决乎；

7队询、先導(dǎo)壓力控制；

派克油泵優(yōu)點(diǎn)

派克油泵采用具有國(guó)際九十年人先進(jìn)水平的新技術(shù)--雙圓弧正弦曲線齒型圓弧构诚。它與漸開線齒輪相比蚌斩，優(yōu)點(diǎn)是齒輪嚙合過程中齒廓面沒有相對(duì)滑動(dòng)，所以齒面無磨損范嘱、運(yùn)轉(zhuǎn)平衡送膳、無困液現(xiàn)象，噪聲低斤间、壽命長(zhǎng)穆烹、效率高。該泵擺脫傳統(tǒng)設(shè)計(jì)的束縛稿棚，使得齒輪泵在設(shè)計(jì)败何、生產(chǎn)和使用上進(jìn)入了一個(gè)新的領(lǐng)域。

派克油泵設(shè)有差壓式安全閥作為超載保護(hù)采缎，安全閥全回流壓力為泵額定排出壓力1.5倍诺骏。也可在允許排出壓力范圍內(nèi)根據(jù)實(shí)際需要另行調(diào)整。但是此安全閥不能作減壓閥長(zhǎng)期工作敌菩，需要時(shí)可在管路上另行安裝基恩。

該油泵泵軸端密封設(shè)計(jì)為兩種形式，一種是機(jī)械密封喷总，另一種是填料密封樟闽，可根據(jù)具體使用情況和用戶要求確定植西。
