東京計器油泵TOKYOKEIKI葉片泵特點：

1，本系列是專為低噪音工況而開發的高壓性能子母葉片泵。

2，使用于注塑機械、橡膠機械、壓鑄機械、機床等各種液壓系統中。

3，增加了脈動衰減結構的設計，極大降低了壓力的脈動，使噪音更低，音原則質更流暢。

4，使用加厚的外殼設計，增加了泵的強度和抗震性，同時消音性能更*。

東京機器油泵適用范圍：本產品主要用于船舶，注塑機械，橡膠機械，油壓機械，壓鑄機械，塑料機械，打包機械，工程機械，機床機械，礦山機械，熱壓機械，制鞋機械，陶瓷機械，制磚機械，發泡機械，鍛造機械，流化機械，拉伸機械，等機械液壓配件。

東京計器葉片泵的安裝，

1油泵的支架座結構要牢固，剛性好，并能充分吸收振動，

2油泵可安裝成任何方向，泵和電機軸必須對正，同軸度應控制在0.1mm以內，

3，吸入阻力不應太高，以防產生空蝕現象。

4，注意進油口處連接法蘭，接頭以及整個吸油管道必須密封，防止漏氣。

Features of TOKYO KEIKI Vane Pumps

This series is a high-performance cartridge vane pump specially developed for low-noise operating conditions.
Widely applied to hydraulic systems of injection molding machines, rubber machinery, die-casting machines, machine tools and other equipment.
Equipped with pressure pulsation damping structure design, which greatly reduces pressure pulsation, delivers lower noise and smoother operation.
Adopts thickened housing design to improve structural strength and vibration resistance, with superior noise reduction performance.

Application Scope

This pump serves as a hydraulic component for marine equipment, injection molding machines, rubber machinery, hydraulic machinery, die-casting machines, plastic machinery, balers, construction machinery, machine tools, mining machinery, hot pressing equipment, shoe-making machinery, ceramic machinery, brick-making machinery, foaming equipment, forging machinery, fluidized bed equipment, stretching machinery and other industrial equipment.

Installation Guidelines for TOKYO KEIKI Vane Pumps

The pump support base shall be sturdy and rigid to absorb vibration sufficiently.
The pump can be mounted in any orientation; the pump shaft and motor shaft must be aligned with coaxial tolerance within 0.1 mm.
Avoid excessive suction resistance to prevent cavitation.
Ensure all flanges, fittings and the entire suction pipeline at the inlet are fully sealed to prevent air leakage.
