Product Description

1. Product profile
The overspeed switch series produced by the company is a new series of products developed by absorbing foreign advanced technologies and combined with the needs of domestic users, and the body materials adopt precision pressed aluminum gold processing process. This product is exquisite shape, high switch action precision 'speed series range wide' positive and reverse bidirectional protection ' shell protection level, can withstand wide environmental temperature changes and convenient installation and other prominent collapse points " This series of products are automatic reset and manual reset mechanism.
The product is widely used in all kinds of rotating machines with strict control of speed, such as smelting rolling drive, hydraulic generator set, internal combustion power 'rotating machinery' YZR motor, YZP frequency conversion motor and lifting roll system, etc. Well speed signal with DC speed generator, encoder ' brake and control devices, which is an ideal and reliable protection element.
Products meets GB14048.5-2008 standards.

6. considerations
6.1 The communication between overspeed switch and protected equipment must ensure mechanical requirements, concentricity and self of shaft and shaft installation.
6.2 During installation, remember not to hit and instantly trigger the product.
6.3 The customer must not adjust where the contact is damaged.
6.4 Action setting value is proposed by the customer.

7. Matters needing attention when using:
7.1 The communication between the product and the protected equipment must ensure the equipment installation requirements;
7.2 Contact damaged by customer is fixed according to customer protection equipment requirements, do not replace itself;
7.3 If the specific contact damage setting value requirement, the product is set 1.25 times the mechanical polishing technology as required by the customer.
