2, the loading speed can not be controlled within the specified time loading speed is too fast or too slow, mainly reducer oil viscosity is too small or too large, should clean reducer, and replace the reducer oil.
3. The reason why the measured hardness value is inconsistent with that of the standard hardness block causes the failure and the elimination method: (1) The Brinell hardness tester is not installed; the Brinell hardness tester should be adjusted to the level; (2) the surface of the ball If it is not clean or the diameter exceeds the tolerance, use a micrometer to select a qualified steel ball and change it; (3) The error of the indentation measurement device is too large, and the allowable error of the indentation measurement device should be adjusted to make it ≤±0.5%; (4) Code can not be placed vertically, the weight and the back cover of the hardness tester, should check the hanging ring is hung on the key blade, hanger hanger is straight, otherwise it should be hanging rings on the key blade, straight hanger boom; (5) The verticality of the spindle and the test bench platform, and the coaxiality of the axis of the spindle and the axis of the lift screw is too bad. The verticality of the spindle and the test platform, and the adjustment of the coaxiality of the axis of the spindle and the axis of the lift screw should be analyzed depending on the situation. .
4, Brinell hardness tester repeated loading and unloading caused the cause of this failure and troubleshooting: (1) button switch top rod is too long, the steering switch A, B contacts and A1, B1 contacts can not be disengaged, should adjust the top The length of the rod is fixed; (2) The installation position of the reversing switch is not proper, and the movable baffle cannot touch the pin on the reversing switch, causing the reversing switch to not change direction, and the installation position of the reversing switch should be adjusted.
5, when the Brinell hardness tester loads all stops, the reason for this failure is that the contact points of the reversing switch have burns and ablation phenomena, resulting in poor contact of the contact points. The contact points should be cleaned or replaced with new reversing switches.
6. When the key switch is pressed, the hardness tester does not act, but there is a fault current noise. This fault is caused by the lack of phase of the motor. Check whether the power supply is normal, whether the power plug is plugged in, whether the cable is open circuited, and whether the power switch is in good condition. Whether the motor wiring is connected firmly, whether the motor coil is burned out and whether the contacts of the reversing switch contact are good, etc., should be excluded according to the situation.
Door panel: door panel is made of stainless steel 304 with no frame. Core materials are paper honeycomb, aluminum honeycomb, PU, EPS and etc. The installation sites of door lock, door closer and hinge are reinforced with square tubes of more than1.5mmthickness which are compression moulded by special technology.
Door frame: it is made of completely stainless steel 304. The connection types with wallboards are double-clip type and aluminum connection. The former is applied mostly to machine made wallboard and the latter hand made wallboard. The accessories are double window and lift type sweeping bar. The lock can be famous door lock or the owners can select lock brands themselves.
Specification: common sizes 800X2100, 900X2100, 1500X2100 or1800X2100, can customize to customers` requirements, the materials can be selected according to customers` requirements such as306Lor other special materials.
Features: the stainless steel 304 door we produced are of elegant appearance, sturdy and durable, acid and rotting resistance and thermal insulation. It is the first choice for high-end projects at home and engineering concerning foreign affairs that requires for anticorrosion and high quality such as electronics factory and food factory
