Pressure testing machine should be installed in clean, dry, vibration-free, non-corrosive gas impact room. The installation foundation should be firm and reliable, and the foot bolts should be on the base.
After the machine is installed horizontally, clean and kerosene-soaked cotton yarn is applied to wipe off the rust-proof agent applied on the machined surface of the machine, and then the surface is wiped clean and coated with a thin layer of mechanical oil.
The correct operation method of pressure testing machine mainly includes the following steps:
1. Operators must be familiar with the operation sequence and performance of machine tools. It is strictly forbidden to use equipment with super performance.
Operators must be certified to work after passing training, examination or examination.
3 Before starting, fill oil according to equipment lubrication chart to check whether the oil circuit is smooth. Open valve to regulate system pressure, lubrication pressure, balance cylinder pressure and adjust oil mist device.
4 Check the oil level of the gearbox, start the main motor idle for 5 minutes, move the slider inch to the bottom dead point, adjust the height of the slider, lock the ball head screw locking mechanism.
5. Turn off the main switch of the machine tool and the air switch of the cabinet.
Clean machine tools, lubricate according to equipment lubrication chart.
Attentions in the installation of pressure testing machine During the assembly process, a variety of tools are needed, among which the hand saw is mainly used for processing, manufacturing and assembling parts, as well as sawing various tubing and so on. When using hand saw, the following four points should be paid attention to:
First, when installing a hand saw, the saw teeth must be forward, tightened properly, not too tight or too loose, otherwise it is easy to break.
Second, the starting angle should be small (generally around 15 degrees), the travel should be short, and the pressure should be small.
Thirdly, in sawing, the pressure of pushing saw is not applied in back sawing, and the full length of saw blade is used as far as possible to prolong the life of saw blade.
Fourthly, when the workpiece installed by the pressure testing machine will be sawed off, the pressure should be light, the speed should be slow, the travel should be short, and the operator's arm safety should be paid attention to.
These are the problems that the technicians should pay attention to in the use of the pressure testing machine that they share with you today. Warm Tip: The correct way to choose a pressure testing machine is to know the type and application scope of the pressure testing machine from the manufacturer according to the material and specification of the sample, and also to provide the sample to the manufacturer for a test in order to facilitate the selection of the pressure testing machine.
