Explosion Proof Peristaltic Pump Electric Explosion Proof Peristaltic Pump.Can be installed large flow pump head with maximum flowrate of 12000ml/min (single channel).
A sharp explosion peristaltic pump can be mounted high flow pump head. Speed can be adjusted manually adjust the speed planetary CVT. Used in various environments, in particular, the requirement to use explosion-proof environments.
Explosion-proof pumps are also used to move gasoline, diesel fuel, oil, ground water, potable water, salt water, wastewater, sewage, sludge, slurry and ash slurry, gas and air, powders, and rendering wastes, a variety of liquids, liquids with solids, etc. Explosion Proof Peristaltic Pump,Peristaltic Pump Explosion-Proof,Explosion-Proof Peristaltic Pump,Explosion Proof Peristaltic Pumps Baoding Chuangrui Precision Pump Co., Ltd. , https://www.chuangruipump.com

Center Tip 1. According to the type of roll bearing layout (1) Bearings are different according to their acceptable load direction or nominal touch angle; divided into: . /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. According to the type of roll bearing layout type 1) Bearings are different according to their acceptable load direction or nominal touch angle;
1) Radial bearing----first for rolling bearings with radial load; its nominal touch angle is from 0 to 45. It is different according to the nominal touch angle; it is divided into: radial touch bearing----nominal touch Radial bearing with angle 0: centripetal angle touch bearing----central bearing with nominal touch angle greater than 0 to 45.
2) Thrust bearing----first for rolling bearings that accept axial load; its nominal touch angle is greater than 45 to 90. According to the nominal touch angle, it is divided into: axial touch bearing----the nominal touch angle is Thrust bearing of 90: thrust angle touch bearing----the thrust bearing with a nominal touch angle greater than 45 but less than 90.
(2) Bearings according to the type of their roll; divided into:
1) Ball bearing----roller is ball:
2) Roller bearing----roller is roller. Roller bearing is according to roller type; it is divided into: cylindrical roller bearing----roller is a cylindrical roller bearing; the length of cylindrical roller The ratio of the diameter is less than or equal to 3, the needle bearing----roller is the needle bearing; the ratio of the length to the diameter of the needle is greater than 3; but the diameter is less than or equal to 5mm; tapered roller bearing----rolling The body is a tapered roller bearing; the spherical roller bearing one by one rolling body is a spherical roller bearing.
(3) Bearings can be adjusted according to their operation, and are divided into:
1) Self-aligning bearing----The raceway is spherical, can be used to the angular error and angular movement of the bearing between the two raceways; 2) Non-aligning bearing (rigid bearing)----impedance Bearings with angular misalignment between raceways.
(4) Bearings are divided into:
1) Single row bearings----bearings with one row of rolling elements; 2) Double row bearings----bearings with two rows of rolling elements; 3) Multi-row bearings----bearings with more than two rows of rolling elements , such as three columns, four columns of bearings.
(5) Bearings can be separated according to their components, divided into:
1) Can be separated from the bearing ---- bearing with separate parts, 2) can not separate the bearing ---- bearing after the end of the matching, the ferrule can not be free to separate bearings.
(6) Bearings can be divided into various layout types according to their layout shape (if there is no filling groove, whether there are inner and outer rings and the shape of the ferrule, the layout of the ribs, or even the cage).
2. According to the scale of the rolling bearing, the bearing is classified according to its outer diameter scale.
(1) Miniature bearings----bearings with a nominal outer diameter scale of 26 mm or less; (2) Small bearings----bearings with a nominal outer diameter scale of 28-55 mm; (3) small and medium-sized bearings--- - Bearings with a nominal outer diameter scale of 60-115mm; (4) Medium and large bearings----bearings with a nominal outer diameter scale of 120-190mm (5) Large bearings----the nominal outer diameter scale is 200 -430mm bearing; (6) Extra large bearing----bearing with nominal outer diameter scale of 440mm or more
