Zaozhuang acid unloading pump model

Zaozhuang acid unloading pump model $r $nLC series Roots oil pump new analysis LC series Roots oil pump is an externally driven rotary pump and also an external lubrication pump. There is a pair of drive gears at the front end, which are separate gearboxes with bearing support and some lubricating oil, separated from the conveying medium. The working rotor rotates inside the casing to complete the transportation of materials. Two rotors are installed coaxially with two driving teeth, rotating synchronously. There is no torque transmission between the rotors, so they are not affected by torque and wear very little, greatly improving their service life. An insulation sleeve can be installed on the exterior of the shell, which can be insulated using heat media such as steam, hot water, and thermal oil. Roots oil pump is suitable for transporting crude oil, asphalt

1、 Overview of Stainless Steel Chemical Magnetic Pump:
CQB type fluorine lined magnetic pump is a chemical process pump that applies modern magnetic mechanics principles and uses permanent magnets to achieve non-contact indirect transmission. When the motor drives the outer rotor (i.e. outer magnetic steel) assembly to rotate, the magnetic field lines pass through the isolation sleeve and drive the inner rotor (i.e. inner magnetic steel) assembly and impeller to rotate synchronously through the magnetic field. The medium * is enclosed in the stationary isolation sleeve, thus achieving the purpose of leak free pumping of the medium, solving the shaft seal leakage of mechanical transmission pumps. The fluoroplastic magnetic pump, whose overcurrent components are all made of fluoroplastic, has reasonable design, advanced technology, full sealing, leak free, corrosion resistance and other characteristics. Its performance has reached the advanced level of similar products in the world and has widely replaced imported magnetic pumps.
CQB type fluorine lined magnetic pump is an ideal pump for eliminating running, emitting, dripping, and leaking phenomena in chemical processes, eliminating environmental pollution, creating a "leak free workshop" and "leak free factory", and achieving safe and civilized production.
Stop the operation of the refrigerant water pump. Turn off the main power supply. During normal operation of the emergency shutdown screw refrigeration compressor of the unit, if there is any abnormal phenomenon; To protect the safety of the unit, an emergency shutdown should be implemented. The operation method is to stop the compressor from running. Close the suction valve of the compressor. Close the solenoid valve on the liquid supply pipe of the unit and the outlet valve of the condenser. Stop the oil pump from working. Close the cooling water inlet valve of the oil cooler. Stop the refrigerant water pump, cooling water pump, and cooling tower fan. Cut off the main power supply. The shutdown method for power outage, water outage and other faults during the operation of the unit can refer to the relevant content of emergency shutdown of centrifugal compressors for handling.

2、 Characteristics of Stainless Steel Chemical Magnetic Pump Products:
The design of CQB fluoroplastic magnetic pump not only has the advantages of compact structure, beautiful appearance, small volume, low noise, and reliable operation of ordinary magnetic pumps, but also all its overcurrent components are made of the world's most corrosion-resistant "plastic king" (fluoroplastic), and the isolation sleeve is made of special materials, which have high-strength mechanical properties and eliminate the magnetic eddy current phenomenon of ordinary magnetic pumps. Therefore, CQB fluoroplastic magnetic pump can continuously transport corrosive media such as acids, alkalis, oxidants, etc. of any concentration (strength) without damage. Applicable temperature: -30 ℃ -100 ℃. This series of magnetic pumps can be equipped with pump protectors to prevent damage to pump components or supporting motors caused by idle operation or overload of the unit.

However, it can be reversed in vacuum pipelines or special circumstances. If the medium may cause water hammer, then an electromagnetic valve with anti water hammer function should be selected or corresponding preventive measures should be taken. Try not to keep the solenoid valve energized for a long time, as this may reduce the service life of the coil or even burn it out. In other words, normally open and normally closed solenoid valves are not interchangeable. The inlet side of the steam solenoid valve should be equipped with a drain valve, and the connecting pipe at this location should be inclined. Common faults and troubleshooting of solenoid valves: The solenoid valve does not work after being powered on. Check if the power supply wiring is poor and reconnect the wiring and connectors; Check if the power supply voltage is within the working range - adjust it to the normal position range; Check if the coil has detached and re welded; Replace the coil due to a short circuit in the coil; Is the working pressure difference inappropriate? Adjust the pressure difference or replace the corresponding solenoid valve; Replace the appropriate solenoid valve when the fluid temperature is too high; If impurities cause the main and moving iron cores of the solenoid valve to get stuck, clean them. If the seal is damaged, replace it and install a filter; The liquid viscosity is too high, the frequency is too high, and the lifespan has reached the point of product replacement.
3、 Purpose:
CQB fluorine lined magnetic pumps are widely used in chemical, acid, alkali, smelting, rare earth, dye, pharmaceutical, papermaking, electroplating, acid washing, radio, scientific research institutions, national defense industry and other units to pump acid, alkali, rare and valuable oil liquids, venom, volatile liquids. Especially for the pumping of liquids that are prone to leakage, flammable, and explosive. Choosing a matching explosion-proof motor is more ideal.

Applicable temperature: -20 ° C to 100 ° C.

Stainless steel solenoid valves must be carefully welded to pipelines. If insufficient attention is paid to welding the solenoid valve to the pipeline and stress is not eliminated, deformation may occur. During welding, it is necessary to strictly prevent welding slag from splashing into the valve. The presence of welding slag can damage the function of the valve. If the slag splashes directly onto the valve core, it can directly affect the operation of the solenoid valve, and in severe cases, it can damage the valve core and seat. During pressure testing and purging of pipelines, the regulating valve should be removed and connected with a corresponding straight pipe section to avoid welding slag, iron filings, and other debris getting stuck between the valve core and valve seat. The end of the opened flange of the removed solenoid valve should be securely wrapped with plastic cloth. The method of delaying the service life by working with a large opening allows the solenoid valve to work at a large opening as much as possible, such as 9%.
