1.JYM1280 sand block machine technical introduction:
Differing with semi-automatic fly ash hydraulic brick making machine, automatic unit is with higher productivity and automation level.Usually automatic fly ash hydraulic brick machine’s output is higher, and its end products are more likely to be used in higher building project.Automatic fly ash hydraulic brick machine belongs to the type of hydraulic transmission vibrating.The strength of standard block formed can reach 15Mpa, which is hugely higher than the requirements for compressive strength in national standard.PLC automatic operation is available under computerizing control.8 operators is enough for controlling the whole equipment.

3.Automatic hydraulic sand block machine trouble:
JYM1280 Fly ash automatic hydraulic block making machine easily results in dust pollution.Especially it possibly damage hydraulic system. Hydraulic pump is the key equipment of hydraulic system.There are too much problems happened before.We concluded the following treatment methods:
1) Oil sucking pipe is blocked. Treatment: clean dust out and make it smooth.
2) Oil sucking pipe is filled by air Treatment: make examination carefully
3) The bolt at the top cover of pump loose. Treatment:Tight the screw until stopping the noise.
4) Oil distributor is blocked by dust Treatment: Take apart of it and clean out the dust under the help of manual.
5) Oil bubble Treatment:Check out whether the oil return pipe sinks in the oil or not, and extend the oil return pipe.
6) Oil is viscous Treatment: Choose suitable hydraulic oil to use.
Hydraulic system of fly ash automatic hydraulic brick machine should be checked regularly.A complete set of examination regulation is necessary for decreasing possibility of damage.
