Simple method of cooling crusher bearing seat

Simple method of crusher bearing cooling - 2018 11 - 09 as recently the weather temperature increasing, there is customer feedback crusher bearing temperature rise sharply, the bearing temperature rise above 70 ℃ 80 ℃ alarm jump stop, in order to reduce the crusher bearing temperature, zheng ore machine according to the situation of the customer feedback, crusher bearing temperature reduction methods are summarized for you, for your reference. 1, the causes of high bearing temperature ( 1) Kiln production increase, lowered the cooling effect of cooling machine, gas cooler discharging temperature is high, make the crusher rotor temperature rise, and through the shaft to the bearing, the bearing temperature rise; ( 2) Clinker crusher grease quantity more than half of the bearing cavity volume, due to the excess grease, bearing heating temperature rise; ( 3) Broken clinker in the process of producing a large amount of dust, as part of the fine dust into the bearing seat, make the oil metamorphism in bearing seat, and heat generation. 2, bearing cooling way of improvement ( 1) In clinker crusher respectively under the two bearing oil cavity at the bottom of the horizontal direction drill a 20 mm diameter hole, tapping on both ends, after wearing in circulating cooling water pipe, to cool bearing oil cavity, to reduce the effect of bearing temperature, at the same time access transparent glass tube in the outlet pipe, is advantageous for the observation of the circulating water flow and water quality status; Specific methods as shown in figure 1 a, one of the shaft diameter of 250 mm, the diameter of the end cover of 450 mm, and the length of the bearing is 490 mm, the distance of the lower part of the pitch of cooling water pipe 40 mm, on both sides of the pitch of cooling water pipe in the edge of the distance of 75 mm, upper part of the cooling water pipe hole is apart from the distance is 290 mm, 500 mm high bearing, high seed 50 mm, bold line is the location of the cooling water pipe, As shown in figure 1 b) 。 ( 2) In the crusher bearing upper with compressed air blowing on the upper part of the bearing and shaft surface, cooling effect, and can reduce dust to enter, and compressed air used manual valve control, can be adjusted according to the site condition to stop and open the valve opening. ( 3) To change the original add 2 # his base extreme pressure grease for the mobil his fat, do it less frequently, during oil filling to prevent the excessive grease to join.
