2. Explosive gas mixtures: IIA, IIB, IIC.
3, temperature group: T1 ~ T4.
Indoor and outdoor (IP55)
Explosion-proof blower on the explosion-proof motor configuration description: Can be customized Explosion-proof BT4/CT4/dust explosion-proof blast blower use The current broad range of low-voltage explosion-proof motor products, the basic series is YB series flameproof three-phase asynchronous motor, it is Y series ( IP44) Derivative products of three-phase asynchronous motors. Explosion-proof performance in line with the provisions of GB3836.1-83 "General requirements for explosion-proof electrical equipment for explosive atmospheres" and GB3836.2-83 "Explosion-proof electrical equipment explosion-proof electrical equipment "d""; motor power range is O.55 -200kW, corresponding frame number range is 80-315nun center height; explosion-proof signs are dI, dIIAT4, dIIBT4, applicable to the coal mine underground fixed equipment or factory IIA, IIB level, temperature group is T1— Group T4 flammable gas or vapor and air formed explosive mixture place; main body enclosure protection grade is IP55, also can be made into IP%4, junction box protection grade is IP55; rated frequency is 50Hz, rated voltage is 380, 660V The motor insulation class is Class F, but the temperature rise of the stator winding is evaluated according to Class B, with a large temperature margin. In the fan industry, the low-voltage explosion-proof three-phase asynchronous motor derived series of fan-specific YBF series (frame height is 63-160mm).
The main features of explosion-proof blowers are:
(1) The correspondence relationship between power level, installation size, and rotation speed is the same as DIN42673. Taking into account the inheritance of the YB series and the interchangeability of the Y2 series, necessary adjustments have been made and are more effective and applicable.
(2) The whole series adopts Class F insulation, and the temperature rise is assessed according to Class B. Its explosion-proof principle is mainly to use explosion-proof measures of dielectric isolation ignition source to achieve the purpose of electrical explosion-proof;
(3) The noise limit value is lower than that of the YB series, and it is close to the I-class noise of the YB series. The vibration limit is equivalent to the YB series.
(4) Shell protection rating increased to IP55.
(5) Low-noise deep-groove ball bearings are used in the entire series, and the motor center is set at 180 mm or more for the oil discharge device.
(6) Motor cooling fins have parallel horizontal distribution and radiation distribution, mainly parallel horizontal distribution.
Explosion-proof blowers are mainly used in: chemical industry, coal mining industry, medical equipment, gas transmission
Explosion-proof blowers Ordering instructions 1 The user must provide engineering design information, technical requirements, etc.
2 indicate the product model specifications, explosion-proof grade, shell material and topcoat color requirements;
3 If there are other special requirements, they can be negotiated and negotiated when ordering.
