    • The invention relates to a pump testing system with energy recovery which provides saving on electric energy required for the pump tests such as quality control and performance life test which are compulsory for the manufacturers and repairmen to conduct. Said system comprises a tank (1) in which the oil to be drawn by the test pump (7) to be tested therein is provided and an electric motor (10) to which said test pump (7) is connected. The oil drawn from the tank (1) by the test pump (7) with the operation of said electric motor (10) is transferred to the shaft of the electric motor (10) by a transmission element or to the hydraulic motor (9) connected to the extended back shaft. The oil pressure is increased to an extent allowed by the electronically controlled proportional pressure relief valve (5) in the hydraulic motor (9) output line and upon opening of the pressure relief valve (5), the pressure oil drives the hydraulic motor (9) coupled with said electric motor (10). Thus, energy recovery is achieved by re-supply of the torque generated in the hydraulic motor (9) to the system. Said system comprises control blocks (6) controlling the system with the information received from the measuring devices such as flow meter, torque meter, tachometer, and pressure transmitter measuring the data such as flow rate, pressure, and torque in the system.
    • 本发明涉及一种具有能量回收的泵测试系统,其提供对制造商和维修人员必须进行的诸如质量控制和性能寿命测试的泵测试所需的电能的节省。 所述系统包括一个罐(1),其中设置有待测试的试验泵(7)被抽吸的油和一个连接有所述试验泵(7)的电动机(10)。 通过所述电动机(10)的操作由所述测试泵(7)从所述箱(1)抽出的油通过传动元件或所述液压马达(9)传递到所述电动机(10)的轴, 连接到延伸的后轴。 油压增加到液压马达(9)输出线中的电子控制比例压力释放阀(5)允许的程度,并且在压力释放阀(5)打开时,压力油驱动液压马达(9) )与所述电动机(10)联接。 因此,通过将在液压马达(9)中产生的扭矩重新供应到系统来实现能量回收。 所述系统包括利用从诸如流量计,扭力计,转速计和压力变送器等测量装置接收到的信息来控制系统的控制块(6),测量系统中的流量,压力和扭矩等数据。

    • An object is to provide a cylinder device which can be used over a long period of time. The cylinder device includes a damper (10), a pump (30), a motor (31) and an external tank (24). The damper (10) has a cylinder (11), a first bracket (12), a piston (13), a piston rod (14) and a second bracket (15). The piston (13) is slidably inserted into an interior of the cylinder (11) . The piston rod (14) is inserted into the cylinder (11) and connects the piston (13) to an end located in the cylinder (11). The pump (30) is disposed at one of right and left sides with respect to a central axis of the cylinder (11). The motor (31) is disposed at the one side which is the same side as the pump (30) with respect to the central axis of the cylinder (11). The external tank (24) is disposed at the other side with respect to the central axis of the cylinder (11).
    • 目的在于提供一种长时间使用的气缸装置。 气缸装置包括阻尼器(10),泵(30),马达(31)和外部箱(24)。 阻尼器(10)具有气缸(11),第一支架(12),活塞(13),活塞杆(14)和第二支架(15)。 活塞(13)可滑动地插入气缸(11)的内部。 活塞杆(14)插入到气缸(11)中,并将活塞(13)连接到位于气缸(11)中的一端。 泵(30)相对于气缸(11)的中心轴线设置在左右两侧的一侧。 电动机31相对于汽缸11的中心轴线配置在与泵30相同侧的一侧。 外箱(24)相对于气缸(11)的中心轴设置在另一侧。
