CZ series standard chemical pump is a horizontal, single-stage, single-suction centrifugal pump. Its size and performance meet DIN24256/ISO2858 standards. The performance range of CZ series standard chemical pump includes all the performance of IH series standard excellent pump. Its efficiency, cavitation performance and other indexes exceed IH type pump and can be interchanged with IH type pump.
Main use
Conveys low or high temperature liquids; neutral or corrosive liquids, clean or liquid containing solid particles. Especially suitable for chemical and petrochemical industry, oil refinery, paper mill and paddle industry, sugar industry.
Conveying medium
1. Inorganic and organic acids such as sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid at various temperatures and rolling degrees, alkaline solutions such as sodium hydroxide and sodium carbonate at various temperatures and concentrations, and various salt solutions. Various liquid petrochemical products, organic compounds, and other corrosive raw materials and products.
Model meaning
Example: CZ32-160
CZ-Standard Chemical Pump
32-import and export caliber (mm)
160-Nominal diameter of impeller (mm)
Product Advantages
1. cz chemical pumps are coaxial, with good concentricity, low vibration, low noise and stable operation.
2, the selection of different materials of castings and seals, can transport water, warm water, hot water and a variety of different liquid media.
3. Y2 and YX3 high-efficiency and energy-saving motors are adopted, equipped with domestic high-quality bearings, with large starting torque, high efficiency, low vibration, low noise, reliable operation and long service life.
4, reasonable selection of mechanical seal material, to ensure that the long-term operation of the pump without leakage, saving operation and management costs of more than 50%.
5. When imported mechanical seals and bearings are used, the product reliability is stronger.
Structural features
Standard chemical process pump body:Horizontal rear door structure, the pump head and the motor are connected by a coupling, installed on the bottom plate, the impeller is rear-open, three bearings, the shaft seal adopts an external mechanical seal, with a cooling device, and the oil level of the bearing body is used Oil mirror observation; compact and reasonable structure. The pump is cast with feet on the pump body and adopts a foot support structure, which can bear the load from the pipeline and directly transmit it to the foundation, so that the pump rotor will not be bent due to the load on the pump, thus ensuring the bearing and mechanical seal Have the best service life. Maintenance does not need to open the pipeline connected to the pump body, as long as the opening of the bracket and the bolt of the pump body, the two can be separated from the maintenance of the impeller and mechanical seal, simple and convenient.
Impeller:Closed, semi-start, fully open impeller, cz chemical centrifugal pump axial force is mainly balanced by back blades or balance holes, and the residual axial force is borne by the bearing.
Pump cover:It forms a sealed cavity with a sealed gland, and the standard cavity size can be equipped with various sealing types.
Shaft seal:According to different working conditions, packing seal, single-end machine seal, double single-sided machine seal, series machine seal and other forms can be used.
Bearing:The lubrication method is thin oil lubrication, and the oil level is controlled by a constant oil cup to fully ensure that the bearing works under good lubrication.
Axis:With the shaft sleeve protection, to prevent the media directly contact with the shaft corrosion, improve the service life of the shaft.
Rear drag design:Can not move the pump in and out of the pipeline, you can repair, easy to use.

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.
