　　The gypsum pressure tester is a special gypsum testing instrument.It is a special equipment for determining the compressive strength of building gypsum.The product meets the requirements of the GB9776 standard.Be sure to read the instructions carefully before use.It is operated by**experimental personnel to avoid injury caused by improper operation.For more information,please contact our customer service staff.The gypsum pressure testing machine is provided by Shanghai Rongjida Instrument Technology Co.,Ltd.The equipment warranty period is one year.If the product has quality problems within one year,the supplier is responsible for free maintenance.If due to improper operation or man-made damage,our company should also provide repair and replacement services,and the costs incurred by our company will be charged at our discretion.

　　石膏压力试验机由机架、测力、示值、油泵、送油及回油阀等部件组成，各部件均安装于一个座箱上构成一个整体。

　　石膏抗压强度试验机使用操作方法：

　　试验人员在作试验前应对试件A大载荷有所估计，以便选用相应的测量范围，才能得到准确的数据。例如：某试件估计A大载荷不超过50kN的就应选用60kN的量程，而不用150kN用300kN的量程，如估计试件A大载荷不超120kN的就应选用150kN的量程而不选取用300kN的量程，这样是为了保证试验结果数据更能准确。

　　The gypsum pressure tester consists of a frame,force measurement,indication,oil pump,oil delivery and oil return valve,etc.,each component is installed on a seat box to form a whole.

　　Operation method of gypsum compressive strength testing machine:

　　The tester should estimate the large load of specimen A before conducting the test,so that the corresponding measurement range can be used to obtain accurate data.For example,if a test specimen is estimated to have a large load not exceeding 50 kN,a range of 60 kN should be used instead of 150 kN and a range of 300 kN should be used.This is to ensure that the test result data is more accurate.

　　石膏压力试验机的安装、试车及保养：

　　①试验机应安装在清洁、干燥、温度均匀，周围无震动，无腐蚀性气体影响的房子里。

　　②安装地点应位置适当，便于操作和维护保养。安装地基应牢固可靠，地脚螺钉应对准底座。

　　③机体的水平调试方法：

　　用0.10/1000方水平仪测量工作缸台面，找纵横水平至±1格，若超出±1格，可在底座下面加垫铁校正，拧紧地脚螺母。

　　Installation,commissioning and maintenance of plaster pressure testing machine:

　　①The testing machine should be installed in a clean,dry,uniform temperature house without vibration and corrosive gas.

　　②The installation site should be properly located to facilitate operation and maintenance.The installation foundation should be firm and reliable,and the anchor screws should be aligned with the base.

　　③The horizontal debugging method of the body:

　　Use a 0.10/1000 square spirit level to measure the table surface of the working cylinder,find the horizontal and vertical level to±1 grid,if it exceeds±1 grid,you can add horn correction under the base,and tighten the ground nut
