Testing machine maintenance and parts of the old hydraulic universal testing machine sales center

Company Used universal testing machine sales center for the major test Factory production materials testing machine, laboratory equipment (Jinan Experimental Factory, Changchun, Hongshan, Shanghai, Guangzhou, Weihai, Jinhua and other manufacturers) were professional and technical services , spare parts supply; the company has a professional design, renovation, maintenance and other technical services team, we have been in the country a number of "Iron and Steel Group Quality Center", provincial and municipal detection unit laboratories, universities teaching base mechanical tests, metallurgical studies in Nanjing The medium-sized private enterprises, etc. including test equipment maintenance, computer upgrading, accessories, logistics and other services; by the majority of customers. Concrete pressure testing machine First, the functional purpose of this machine is mainly used for concrete, pipe, cement products, hollow bricks, refractories, compressive strength test engineering materials, stone, rubber bearings and other building materials. Necessary equipment roads, railways, bridges, construction, building materials, tertiary institutions and other industries laboratory. The test machine used in compliance with GB / T17671-1999 standard cement mortar compressive strength test, pressure test can be widely used in concrete, brick and other 300KN range. This machine uses hydraulic loading, electronic measuring, with a load figures show that loading speed display maximum load to maintain, as well as overload protection and power data retention capabilities. Second, the main features: 1, the machine uses precision sensors and digital display instrument, store, access and print test results. 2, the machine uses rotary screw to adjust the compression space, greatly accelerated test schedule. 3, accompanied by an increase bending, bending test can be carried out. 4, the machine without debugging, smooth landing, refueling, electrical connection to work. 5, machine calibration is simple, the user can "manual" calibration. 6, the machine uses precision sensors and computer control, automatic storage, access and print test report, print curves. 7, the machine uses rotary screw to adjust the compression space, greatly accelerated test schedule. 8, the machine according to the unit requirements, design their own reports. 9, the machine can be achieved manually, automatic dual control system. Third, the technical parameters: 1, the maximum test force: 300kN2, Test Force showed the relative error:? ≤ ± 1% 3, the loading rate: 0.3KN / S ~ 10KN / S4, loading speed error:? ± 5% 5 , pressure plate size: φ120mm6, piston stroke:? 60mm7, piston diameter:? φ130mm8, oil maximum pressure:? 25MPa9, pump rated flow:? 1.52L / min10, motor power:? 0.75kW11, Host Dimension mm ?: 870 × 450 × 1400mm12, Weight:? 850Kg
