Product Description
FY series submerged pump is a new type of pump produced by this unit on the basis of traditional corrosion-resistant submerged pumps and integrating the advanced technology of the same products of Sulzer Company of Switzerland. The pump cancels the mechanical seal commonly used in other submerged pumps and selects the impeller with unique structure, making the pump highly efficient, energy-saving, non-leakage and long service life, thus being widely used in petroleum, chemical, pharmaceutical, papermaking, metallurgy, sewage treatment and other industries.
Overview
FY series submerged pump is a long-axis vertical centrifugal pump. Its contact part with medium is made of cast steel or stainless steel. The submerged depth varies from 0.5 M-6M according to customer's requirements. The working part is submerged in liquid. It has wide application range and high efficiency. It can be transported without liquid filling. The axial force and radial force generated by pump operation are respectively supported by rolling bearings in the upper part of the liquid and sliding bearings under the liquid, therefore, the operation is quiet and no noise, is a set of environmental protection and energy saving high-tech products.
Structure Description
FY type is mainly composed of pump body, pump cover, impeller, shaft elastic shaft, pipe flange, guide bearing, intermediate nozzle, upper and lower liquid outlet pipe, bearing frame, bottom plate and other parts. The suction inlet of the pump is along the axis direction, and the outlet is parallel to the axis. The rotation of the pump is clockwise when viewed from the motor end.
The vertical motor of FY series submerged pump is fastened to the motor seat with double-headed bolts, and directly connected to the pump through elastic coupling. The pump body, intermediate connecting pipe, bearing frame, liquid discharge pipe and pipe flange are connected to form a whole body and fixed on the bottom plate. The whole pump is installed on the device through the bottom plate. Other main parts of FY pump except the parts contacting the liquid, such as motor seat, bearing frame and bottom plate, are made of cast iron.
The axial force and radial force of the pump (including the water pressure generated in the pump cover, the weight of the impeller and rotor, etc.) are all supported by single row thrust roller bearings, double row radial ball bearings and sliding guide bearings installed in the bearing box. For safe and normal operation, the two rolling bearings shall be lubricated with grease. When the liquid lubricating medium delivered by the guide bearing body contains a small amount of normal particles, the guide bearing shall be lubricated by external cleaning liquid.
FY series liquid pump adopts J-type skeleton oil seal at the gap between the sealing plate and the shaft to prevent the leakage of corrosive gas. According to the viscosity of the conveying medium, the impeller is divided into closed and semi-open type, usually using closed impeller. In addition, the FY series of submerged pumps are divided into structures with intermediate guide bearings and structures without guide bearings due to the different lengths of the extender.
1. The pump is a vertical submersible pump with beautiful appearance and is directly installed on the storage of the transported medium without additional floor space, thus reducing the investment in infrastructure.
2. The mechanical seal is canceled, which solves the trouble that other submersible pumps need frequent maintenance due to easy wear of mechanical seals, saves the operating cost of the pump, and improves the work efficiency.
3, the use of a unique centrifugal double balance impeller, for the transport does not contain solid particles and other clean media, low vibration noise, high efficiency; the use of open double balance impeller, for the transport of not clean with solid particles and short fibers of the liquid, smooth operation, not blocked.
Use
1. The temperature of the conveyed medium is -20~140 ℃
2, cast iron material pump, medium PH value in the range of 5-9.
3. For the pump with open impeller, the diameter of solid particles contained in the conveyed liquid should not exceed 30% of the diameter of the pumped population.

Disassembly and assembly
(1) If the impeller is replaced or checked, the outlet valve can be closed, the flange connecting bolts and the bottom plate connecting bolts can be removed, and the pump can be lifted out of the container with a lifting tool.
(2) hang the bottom plate on the bracket, remove all the bolts of the pump body, take out the pump cover and impeller nut, and tap the pump body with a double hammer to remove the impeller.
(3) for the replacement of rolling bearings or packing, the bottom plate does not move, as long as the motor and the corresponding bracket, remove the pump coupling, gland, round nut, take out the bearing body. To replace the packing, first remove the packing gland, then remove and replace the packing.
(4) The order of assembly and disassembly NB,0 is opposite, and the concentricity of the accessories on the shaft must be paid attention.
Installation, use and maintenance
1. After the pump is assembled, turn the coupling to see if it rotates flexibly. Check whether there is metal friction sound and whether the nuts of each component are tightened.
2. Check the concentricity of the pump shaft and the motor shaft. The left and right difference of the outer circle of the two couplings shall not exceed 0.1mm, and the gap between the end faces of the two couplings shall be kept at 1~2.5mm.
3. The distance between the suction population of the pump and the bottom of the container is 2 to 3 times the suction caliber, and the distance between the pump body and the container wall is greater than 2,5 times the caliber.
4. The outlet pipe of the pump shall be supported by another bracket, and its weight is not allowed to be supported on the pump.
5. Check the rotation direction of the motor to make the rotation direction of the pump conform to the indicated direction.
6. Close the gate valve and pressure gauge on the outlet pipeline and connect the cooling water pipe.
7. Start the motor, open the pressure gauge, slowly open the gate valve of the outlet pipe to the required position, and put the person into normal operation.
8, often check the pump and motor, bearing temperature rise should not exceed 75 ℃, bearing box should add enough butter.
-
1. pump does not start
1, power failure: should check the power switch and wiring.
2, motor wiring failure: should check the motor connection.
Internal blockage of the pump: check whether there is foreign matter in the pump.
4. Motor failure: check whether the motor is damaged.
Water output of 2. pump decreases
1, pump drum cavity leakage: should check the shaft seal, sealing ring and valve is damaged.
2. Inlet valve leakage: check whether the valve sealing ring is damaged.
3. There are foreign bodies in the pump cavity or friction or blockage in the pump: check whether there are foreign bodies in the pump and clean up the deposits in the pump.
Excessive noise during operation of 3. pump
1. The pump chassis is not in close contact with the bracket: the bracket should be reinstalled or replaced.
2. The contact between the pump drum cavity and the pump body is not close: the axial clearance should be adjusted to ensure close contact.
3, bearing damage or foreign matter into: the bearing should be replaced.
4. pump temperature rise
1, pump fire or burn out: should check whether the pump is damaged, replace the undamaged parts.
2, bearing damage or poor lubrication: should check the bearing and lubrication system, replace the bearing, strengthen lubrication.
The above are the common faults of submersible pumps and their solutions. Users should pay attention to regular maintenance and maintenance when using submersible pumps, and eliminate them in time according to specific faults. This can extend the service life of the submerged pump and ensure production safety.
