The stainless steel inner ring high viscosity pump is mainly composed of inner and outer rotors, shafts, pump bodies, front covers, seals, bearings, etc. There are two types of seals: mechanical seals and packing seals. Packing seals are used for high temperature, high viscosity and highly corrosive media.
When transporting materials that are easy to crystallize, the front cover and pump body can be designed with thermal insulation jackets that can be heated and melted by steam during operation. The pump can be equipped with a safety valve. When the pump or pipeline system is overpressured, the safety valve opens to form an internal backflow to ensure system safety.
The pump device consists of a pump, motor and base. There are two transmission modes: bridge type and direct coupling type.
Seeing from the motor end toward the pump, it rotates clockwise.
The stainless steel high viscosity pump has an internally toothed driving gear (outer rotor) that drives the inner rotor to rotate in the same direction in the fully enclosed pump body. The crescent plate of the pump body and front cover separates the suction inlet and discharge outlet. When rotating, a negative pressure is formed at the suction port, and the liquid is sucked into the rotor, bringing the liquid to the discharge port and being pressured out of the pump body to complete the delivery of the liquid.
Overview of series of internal ring high viscosity pumps
Series of ordinary (stainless steel) internal ring high viscosity pumps are new types of pumps developed according to the needs of petroleum, chemical, paint, grease, medicine, dye, food and other industries. Positive displacement pumps are widely used in transporting media of different properties and viscosities due to the different materials and unique structures available for this product.
Applicable medium temperature: -℃ ℃ (and the applicable temperature is -℃ ℃).
Applicable medium viscosity:.(The applicable viscosity of and is.).
Advantages of the series of internal ring high viscosity pumps
The liquid is transported smoothly, without pulsation, vibration, low noise.
It has strong self-priming performance.
The correct selection of parts materials can transport a variety of corrosive media and the operating temperature can be ℃.
The inner and outer rotors have the same steering direction, with little wear and long service life.
The rotation speed of the pump has a linear functional relationship with the flow rate, and the rotation speed can be appropriately changed to change the flow rate of the pump.
Especially suitable for conveying high viscosity media.
Notes:
When the stainless steel high viscosity pump starts to run, the housing of the gear pump is filled with the liquid to be transported for safe start. If the ambient temperature is below freezing point, hot steam should be introduced into the pump for preheating before starting the gear pump. The rotation direction of the high viscosity pump should be consistent with the oil inlet and outlet. If the gear pump is running for the first time or is used after being idle for a long time, it is best to run it for about an hour under no-load or small load conditions. If abnormal temperature rise, leakage, vibration and noise are detected in advance during the running-in stage, the machine should be stopped for inspection.
During daily use of high viscosity rotor pumps, please note that electric oil pumps should be stored in a dry and clean environment without corrosive gases. Preserve each part and replace the same parts. When disassembling and inspecting the high-viscosity rotor pump, each part should be preserved. Pay special attention to the explosion-proof surface of the explosion-proof parts so that they cannot be damaged or roughened. Insulation liners and bushings must be replaced if damaged. New identical parts must not use substitute materials with lower performance than the raw materials or parts that do not meet the original specifications. When assembling, all parts should be installed in their original positions without omission.
High viscosity rotor pumps are often greased. Electric oil barrel pumps run at high speeds. Grease is easy to evaporate, so the lubrication at the bearings must be kept clean and replaced. High viscosity rotor pumps should be inspected and repaired frequently. Electric oil drum pumps should be inspected and repaired frequently. The power cord must be checked: whether the internal wiring plug switch is good and the insulation resistance is normal. Is the brush tailstock loose? The commutator has good contact with the brushes. The armature winding is expanded and the stator is Whether there is an appropriate interruption in the winding, whether the bearings and rotating parts are damaged, etc. Pay attention to the insulation resistance of high-viscosity rotor pumps. Electric liquid pumps that have been left unused for a long time or used in humid environments must use a meter to measure the insulation resistance of the windings before use. If the insulation resistance between the winding and the motor shell is less than 1, the winding must be dried.
Although the high-viscosity rotor pump bonding process is relatively simple, the actual construction requirements are quite strict. High bonding strength may not be obtained simply by selecting a good adhesive. It is necessary to select the appropriate adhesive and strictly follow the correct process method to apply the appropriate adhesive and strictly follow the correct process method to achieve a satisfactory bonding effect. In recent years, surface bonding technology has been widely used in equipment maintenance in my country and is suitable for repairing parts and equipment made of various materials. Its working principle is to directly apply the adhesive added with special fillers such as molybdenum disulfide, metal powder, ceramic powder and fiber to the surface of the material or part to make it wear-resistant, corrosion-resistant and mainly used for surface strengthening and repair. Its process is simple, convenient and flexible, safe and reliable, and does not require special equipment. Just apply the prepared glue on the surface of the cleaned parts and trim it after curing. It can often be operated at room temperature and will not affect the parts' thermal power equivalent. and deformation etc.
In normal use, high viscosity rotor pumps should pay attention to daily maintenance work and carry out good control according to certain problems and principles, which can fully demonstrate certain control and production, obtain good maintenance methods and extend the service life.
