The sand making machine is one of the most typical tools in crushing and sand producing manufacturing line, though its motor is generally damaged; machine professionals holds view that there are lots of factors bring about the injury of compound crusher motor; aside from traditional failure reason for frequent motor power equipment, the working fault of compound crusher also can injury the motor, shown as follows: The dependability and sensitivity of your automatic pressure switch; the starts and stops of compound crusher are generally managed from the automated pressure switch (pressure relay) immediately driving alternating recent contactor.

Resulting from the sand making machine functions in harsh problems in long lasting, the dress in of rotor bearing is exacerbated. The rotor is irreplaceable for crusher to ensure that crusher can't function without it. However, additionally it is fragile; the bearing rotor is not only high priced, but additionally replaced difficultly, normally resulting in the cut-off reduction. How to take helpful measures to enhance the rotor bearing existence is a vital matter that our shoppers concern about, asking us pay more awareness: To start with, make right selection of rotor-bearing model. Double row radial spherical roller bearing with strong bearing capability and aligning performance, it's worthy staying picked. Additionally, the rotor which can be with style life of 5000 ~ 10000h is acceptable. Second, increase the force status of crusher bearing. The impact load doing work about the bearing will depend on the impulse acting within the rotor as well as the support versatility of bearing. Rising bearing help versatility will lower the impact load working to the bearings. To this finish, we could include rubber sheet with ideal thickness amongst the bearing as well as the help frame to enhance the bearing help flexibility and to obtain the function of extending the support daily life.

The automated stress switch generally adopts mechanical construction, which act on get in touch with through the compress and release of spring. The congenital deficiencies or improper adjustment of automatic pressure switch could cause motor injury. The electrical handle (specially for low-power sort) is comparatively basic, they may be frequently function independently by stand-alone group and lying in un-professional operation occasions with torpid repair and maintance, which reasonably maximize in repeat growth charge of failure.
