China Suncenter Brand Model: 28: 1 Pressure Ratio 220 Bar Output High Pressure Pneumatic Hydraulic Test Pump

产品描述

Suncenter brand Model:  28:1 pressure ratio air driven hydraulic pump for pressure testing
We offer the most complete range of Air driven liquid pump models in the industry measured for:

1. Capability of ultimate pressure, flow or output horsepower.
2. Compatibility with a broad variety of liquids, such as oil, water and chemical applications.

SUNCENTER pumps are air driven at a drive air pressure of 1bar to 8bar (14.5 psi to116 psi) by the normal air compressor. Basically the principle of operation is similar to a reciprocating amplifier where control of the piston at the end position is regulated by a pilot operated 4/2 way valve.

Suncenter pumps feature a large air piston joint to a smaller diameter plunger. The pressure ratio is the difference of these 2 areas and is the method of determining maximum outlet pressure. Higher pressures obtained by using higher pressure ratios.Suncenter model numbers reflect the pumps nominal pressure ratios, while the technical data indicates exact ratios. The outlet pressure is easily to set through a simple air regulator. By multiplying the pressure ratio by the available shop air pressure, the nominal liquid pressure can be calculated.

SUNCENTER pumps are self priming. In general it is not necessary to use an air line lubricator.
The liquid to be pumped flows into the suction chamber by the up-stroke of the drive piston. By this suction effect, the inlet check valve is opened and the outlet check valve is closed. The down-stroke generates the pressure at the liquid side. The inlet check valve is closed and the outlet check valve is opened by the generated pressure. SUNCENTER liquid pumps cycle automatically, where the pressure is built up the numbers of cycles slow down, the pump stops automatically when the output pressure forces are equal. The pump restarts with a slight drop in the outlet pressure or an increase in the air drive pressure. Pump performance can be affected by a number of conditions, such as freezing of muffler or pilot valves (which is caused by moisture in air lines), inadequate inlet air line sizes and dirty filers. Don’t reduce the indicated port sizes and consult SUNCENTER for exact flow conditions not shown in charts.

Suncenter CZPT Series Pneumatic (Air driven) Liquid Booster System
Suncenter- CZPT Series Pneumatic(Air driven) Hydraulic Power Packs
SUNCENTER- Hydraulic power packs(Liquid pump system) are compact and delicacy solution tailored to customer specific requirements with air driven liquid pumps as well as all accessories to be fitted and installed on the frame or in closed cabinet.
To operate this system, the pressure gauges, valves and pressure regulators have to be fitted on panels. The outlet pressure is easily to be set through a simple air regulator. The pump stops automatically when this end pressure is reached and restarts with a slight drop in the outlet pressure or an increase in the air drive pressure. SUNCENTER Hydraulic power packs are available with wide range of pressure ratios make these series of pumps ideal for powering a variety of oil/hydraulic operations. The maximum operating pressure up to 640 MPa.
As the pressure will be generated by means of a pneumatically operated pump,the electric connection will not be necessary. To operate this system, the air driven liquid pump have to be equipped with the air control unit combined filter and water separator, pressure-regulating valve, pressure control gauge as well as manual relieve valve. In this operation, the pump will be mounted to the stainless steel tank in the closed cabinet in a compact and space saving manner. Pressure gauges, valves and pressure regulators will be fitted on panel.
The desired operating pressure can be attained by adjusting the driving air pressure. When the driving air pressure and the output pressure reach the balance, the pump stops filling pressure and the output pressure stays at the preset value. This hydraulic unit can be used for all kinds of pressure testing and test tools for research and test institutes or for other functions requiring a determined pressure.

空气压缩机类型选购指南

空气压缩机种类繁多，了解每种类型的特点至关重要。本文将讨论单级空气压缩机、低噪音压缩机和双活塞压缩机。不过，在购买空气压缩机之前，请务必阅读我们的各类空气压缩机选购指南。这样，您就能掌握所有必要信息，从而为您的企业做出正确的选择。

单级空气压缩机

单级空气压缩机是大多数通用用途的理想选择。它们动力强劲，足以驱动气动工具，而且发热量较低。然而，单级空气压缩机不适用于重型工业用途。但它们可用于各种场所，包括汽车修理厂、加油站和各种制造工厂。它们也适用于钻井和其他高压环境。
这些空气压缩机是家庭使用的理想之选，也适用于小型企业、承包商和小型商店。这些压缩机具有连续工作循环能力、铸铁压缩机泵，泵的使用寿命至少为 5000 小时。它们还配备了先进的功能，包括过氧化氢保护电机、自动启动和控制、储气罐和电源线。这些压缩机维护成本低，可以为您节省大量资金。
单级空气压缩机通常比双级空气压缩机更便宜、更轻便。单级空气压缩机也更便于携带，这对于小型项目来说是一大优势。虽然双级压缩机的排气量（CFM）更高，但它们功率更大、体积更大，因此不适合小型或家庭使用。所以，务必先确定空气压缩机的用途，并根据自身需求选择合适的型号。
单级空气压缩机由活塞和储气罐组成。活塞在气缸内快速运动并对气缸施加压力。这意味着活塞的运动速度不能超过气缸外的气压。每个级别的活塞运动方式都相同。对于家庭作坊和小型汽车修理店来说，单级空气压缩机是一个不错的选择，因为它允许您在不影响泵寿命的情况下控制压力。
单级空气压缩机通常比双级空气压缩机便宜，但并非所有应用场景的最佳选择。如果您只是偶尔使用空气压缩机，单级型号的可靠性远高于双级型号。这两种压缩机的主要区别在于每级压缩的空气量。双级空气压缩机虽然储气量更大，但产生的压力也更高。

旋转叶片式压缩机

旋片式压缩机利用离心泵压缩空气。转子偏心安装在壳体内，几乎与叶片接触。当转子旋转时，进入泵的空气被截留在叶片之间。这种压缩空气在转子旋转的过程中被压缩。叶片是由碳纤维或石墨复合材料制成的小块材料。根据应用的不同，叶片也可以采用不同的材料制成。
虽然旋片泵并不常用于生产压缩空气，但它们在汽车和液压领域应用广泛。您很可能在生活中某个时候使用过旋片泵。这些泵在真空和压缩空气行业也很常见。因此，许多人可能没有意识到它们仍然存在。旋片泵的特点是带有槽口，叶片可以在转子内滑动进出。
旋转叶片式压缩机内部包含一个鼓轮和一个转子。转子偏心安装，表面设有槽和沟槽。其进气口和排气口偏离中心，使叶片能够在离心力的作用下向外运动。由于转子高速旋转，空气被困在叶片之间。这些空气随后在旋转的转子作用下被压缩。
旋转叶片式压缩机易于维护和修理。更换碳叶片只需15分钟和常用工具即可完成。碳叶片的使用寿命通常为9至18个月，具体取决于系统工作压力。购买旋转叶片式压缩机之前，请务必检查其是否经过性能测试并享有保修。通常，保修范围涵盖转子/定子室，但不包括叶片或空气过滤器。您还应该检查该设备是否享有雷击或进水损坏保修。
旋片式压缩机是制造业不可或缺的一部分。许多制药厂都依赖旋片式压缩机来控制设备。其他使用旋片式压缩机的行业包括塑料、木材加工、天然气以及医疗和牙科领域。旋片式压缩机的优势众多，远远超过其相对于螺杆式压缩机的任何缺点。例如，旋片式压缩机的使用寿命可比传统压缩机延长一倍。

低噪音型旋转叶片式压缩机

如果您正在寻找旋片式空气压缩机，那么您来对地方了。CZPT 的 LV 系列旋片式空气压缩机具有低噪音、结构紧凑、集成性强等优点。除了低噪音特性外，它们还配备了大型过滤系统，可提供高质量的压缩空气。LV 系列产品也秉承了 CZPT 一贯的可靠性和高质量。
这种压缩机利用离心力运行，其最高和最低运行转速均受到限制。它们的功率只有螺杆压缩机的三分之一，最高转速也低得多。此外，由于离心力不足以使叶片与气缸边缘紧密贴合，因此在高转速下叶片容易磨损。即使仅以一半的额定功率运行，它们也会消耗高达额定总能量的 80%。
由于活塞式压缩机噪音较大，工厂和车间业主开始安装降噪柜和其他降噪设备。但是，旋片式压缩机的噪音远低于传统真空压缩机，而且维护成本也低。旋片式压缩机在多个行业中也发挥着极其重要的作用，例如汽车及汽车涂装行业、乳制品行业以及挤奶设备等。
如果您有一个深水池塘，旋转叶片式空气压缩机套件可以将水泵送至 20 英尺深。这足以满足 2 到 5 个扩散器的气流需求。1/4 马力的旋转叶片式套件可提供约 4.2 CFM 的风量。它还有助于提高池塘的循环和氧气含量。最后，1/4 马力的套件也足以清理池塘底部。
旋片式和螺杆式空气压缩机是目前最流行的两种空气压缩机。虽然它们在很多方面都很相似，但相比活塞式空气压缩机，它们用途更广泛、更耐用。与活塞式空气压缩机相比，它们使用的角接触球轴承更少，维护频率也更低。此外，旋片式和螺杆式空气压缩机的噪音更低，价格也更便宜。

双活塞旋转叶片式压缩机

旋片式压缩机和螺杆式压缩机的应用类似，但两者各有优缺点。本文将比较二者的优势，并重点介绍它们之间的差异。虽然两者都广泛应用于工业领域，但旋片式压缩机更受许多行业的青睐。这类压缩机的应用范围也很广，从汽车气动工具到挤奶机，无所不包。此外，旋片式压缩机还具有比活塞式压缩机更安静的优势。
目前的共轨位置可能不适用于压力旋流喷油器，但新的位置经过测试，在比能量值方面有所改进。此外，目前的位置对于外置油泵并非必需。然而，质量的吸入和排出必须极其谨慎。本文重点介绍旋转叶片式压缩机的设计和效率。您可以在以下参考文献中找到有关这种新设计的更多信息。
这种压缩机的优点是成本低、体积小、易于维护，因此在小容量应用中更受欢迎。此外，它们还带有集成叶片。旋转叶片可以缩小气隙，将空气压缩至出口。与活塞式压缩机相比，这类压缩机价格更低、可靠性更高。因此，您应该选择价格最低的型号。您也可以选择无油的旋转叶片式压缩机。
滑片式压缩机是另一种常见的压缩机类型。它只有一个气缸连接到压缩机，能够在低速下运行。这种设计还能减少摩擦并保持容积效率。然而，滑片式压缩机的摩擦损失较大。如果您正在寻找更高效的旋转式压缩机，那么滑片式压缩机是最佳选择。虽然滑片式压缩机已经存在了一个多世纪，但它仍然是一种相对较新的技术。
这些压缩机易于安装和维护，而且比活塞式压缩机更安静，价格也更低。其高能效和低价格使其成为任何商业或工业应用的理想之选。如果您正在寻找一款小型紧凑型压缩机，旋转叶片式压缩机已被证明是满足您需求的最佳选择。此外，它的使用寿命也很长。
