Roots blower and maintenance of the three principles

　　1, the principle of necessity

　　All used parts, tear open come down to check, nothing more than the following several ways: one is the quality is good, or although have wear but not for repair also can continue to use; 2 it is flawed, but after the repair still can continue to use; 3 there is a larger defects, difficult to repair or repair of little value, need to be replaced.

　　In the process of inspection, the repair parts should be timely repair the change, otherwise affect the maintenance quality blower. But if has no effect on the part of the blind to repair, or will it can continue to use the parts in advance replacement, it will cause waste, increase the maintenance cost, therefore, to determine whether parts change, in general should follow the principle of "it is necessary to repair the change".

　　2, the principle of reliability

　　Defective parts need to change, but whether repair or change, should follow the principle of "can use". Select the repair parts, repair shall restore or basically restore the original after manufacturing accuracy, satisfy the technical requirements of parts. Usually these requirements, including part size error, surface roughness, position tolerances and surface hardness, etc. Generally speaking, the wear less severe cases, wall plate and rotor group, etc., after repair can still use mostly, usually choose such defects repair; But once the spare parts such as bearings, gears, and oil seal damage can be difficult to repair, barely used usually leads to more trouble, so generally choose change when maintenance.

　　3, the principle of economy

　　Whether can repair parts must repair, and choose not to change, should also be economical comparison of repair and replacement.

　　Yi, robot blower features:

　　1, casting resin sand casting technology, yi tai fan castings have good quality assurance.

　　2, the impeller design, in strict accordance with the theory of involute and simulation on computer, what should be done before the machine rotation balance experiment many times, fully guaranteed the meshing characteristic of involute, effectively reduce the leakage and improve the efficiency.

　　3, chassis, panels by high precision digital display coordinate boring machine processing, high precision and stable quality.

　　4, into the exhaust and equipped with muffler with spiral structure, make the inlet and exhaust pulse flat, little vibration, low noise.

　　5, lubrication, splash lubrication, drop tank is used to not only make the lubrication is more reliable, and solve many of the shortcomings of grease lubrication, effectively improve the service life of bearing.

　　6, the sealing structure is reasonable, the oil and gas can not enter the chassis, therefore, the output air clean, oil free.

　　7, bearings, triangle adopts imported parts. Bearing is made in Japan, the triangle is made in America.

　　8, fan gear is made of 20 crmnti after carburizing treatment, grinding, precision up to 5, tooth surface is more wear-resisting, can significantly reduce gear noise.

　　9, yi, robot -- fan before delivery after 48 hours of trial operation, debugging qualified to delivery, guarantee the quality of roots blower for the factory.

　　After-sales service: good roots blowers robot if during the warranty period appear quality problem, can solve the company on-site maintenance personnel will serve to the scene within 48 hours, if the fan is a major quality problem, you can change the new fan.
