六,主要结构:
★压力机机体部分
1,机架3为球墨铸铁的结实机架,机架上部装有螺母4、连接丝杆2,在丝杆末端有凸球座5及上承压板6,在试件受压时可以自动调整上承压板与试件受压面的接触吻合。根据试件大小,可以转动手轮1,调节丝杆至适当高度。
2,下承压板表面刻有定位线,便于试件放置于中心位置。下承压板7放于活塞8上,在下承压板下面装有防尘罩防止碎屑和杂物落入油缸11里面。当活塞受到油压上升时,推动下承压板向上顶压试件。
3,油缸11座落在机架的下部,在油缸的内壁上部嵌有复合密封圈9,防止在高压时活塞和油缸间的油液溢出,油液溢损极微。油缸后方左上侧有一溢油管,直接让油缸上面的溢油流回油箱,因此可以保持机器四周的洁净。
4,若作混凝土抗压试验时,建议用户可自制一斜斗,向后侧倾斜,以便清除碎块,为防止试件经常推移而磨损下承压板,建议可自制适合试件大小的垫板,但需热处理(硬度HRC55以上),用久磨蚀后,便于更换。
★液压控制系统
本压力试验机系统包括电动机及高压油泵、送油阀、回油阀、油箱等。油泵及电动机14通过联轴器相连,座于油箱13上,高压油直接进入送油阀16。当送油阀关闭时,油直接流回油箱,当送油阀打开,回油阀15关闭时,高压油进入油缸,并传至传感器,传感器将信号传至测力仪18。
★测力系统
本压力试验机系统由液压传感器、信号放大转换器、数据处理、打印机及控制操作面板、传动加载机构等组成
Six, the main structure:
★ press body part
1. The frame 3 is a solid frame of ductile iron. The upper part of the frame is equipped with a nut 4 and a connecting screw 2. At the end of the screw rod, there is a convex ball seat 5 and an upper bearing plate 6, which can be automatically pressed when the test piece is pressed. Adjust the contact between the upper bearing plate and the pressure receiving surface of the test piece. Depending on the size of the test piece, the handwheel 1 can be turned to adjust the screw to the appropriate height.
2. The surface of the lower bearing plate is engraved with a positioning line to facilitate the placement of the test piece in the center position. The lower bearing plate 7 is placed on the piston 8, and a dust cover is placed under the lower bearing plate to prevent debris and debris from falling into the cylinder 11. When the piston is subjected to the oil pressure rise, push the lower bearing plate to press the test piece upward.
3. The cylinder 11 is located at the lower part of the frame, and a composite sealing ring 9 is embedded in the upper part of the inner wall of the cylinder to prevent oil from overflowing between the piston and the cylinder at a high pressure, and the oil leakage is extremely small. There is an oil spill pipe on the upper left side of the cylinder to directly drain the oil from the cylinder back to the tank, thus keeping the machine clean.
4. If it is used for concrete compression test, it is recommended that the user can make a inclined bucket and tilt it to the rear side to remove the broken pieces. In order to prevent the test piece from being frequently worn and wear the lower bearing plate, it is recommended to make a pad suitable for the size of the test piece. Plate, but heat treatment (hardness HRC55 or more), easy to replace after long-term abrasion.
★Hydraulic control system
The pressure testing machine system includes an electric motor and a high pressure oil pump, a fuel delivery valve, a return oil valve, a fuel tank and the like. The oil pump and the electric motor 14 are connected by a coupling, and are seated on the oil tank 13, and the high pressure oil directly enters the oil delivery valve 16. When the delivery valve is closed, the oil flows directly back to the tank. When the delivery valve is opened and the return valve 15 is closed, the high pressure oil enters the cylinder and is transmitted to the sensor, which transmits the signal to the load cell 18.
★Measurement system
The pressure testing machine system is composed of a hydraulic sensor, a signal amplification converter, a data processing, a printer and a control operation panel, a transmission loading mechanism, and the like.
