Price of Tai'an acid unloading pump

The price of the acid unloading pump in Tai'an is $r $n, and the following situations require the duty officer to handle them on their own: replacing the light bulb and; Choose DC grounding. In a three-phase four wire power supply system, why is it not allowed for some equipment to be grounded while others are protected by grounding? Answer: When a protective grounding electrical equipment collides with the shell, due to the much higher resistance of the ground than the neutral line, a short circuit power supply is formed through the grounding electrode of the shell and the ground, which is often insufficient to activate the automatic switch and action. The grounding power supply also increases the potential of the neutral point of the power supply, causing a ground voltage to appear on the shell or cabinet of all electrical equipment with grounding wires, which can cause more opportunities for electric shock.

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.
KCB18.3-83.3 pumps are composed of three oil resistant rubber rings and a retaining ring with a middle lining. The sealing degree is adjusted by adjusting the two nuts on the compression cover, and the bearings are copper based powder oil containing bearings. In addition, stainless steel gear pumps can use packing seals made of flexible graphite with good elasticity, high and low temperature resistance, stable chemical properties, and self-lubricating properties as packing. The stainless steel gear pump is equipped with a safety valve. When the pump or discharge pipeline malfunctions or the discharge valve is mistakenly closed, resulting in high pressure and high pressure impact, the safety valve will automatically open, removing some or all of the high-pressure liquid and returning it to the low-pressure chamber, thereby providing safety protection for the pump and pipeline.

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.

A: Method: The 1hp water-cooled chiller can be equipped with an 8-ton locking force injection molding machine, and the temperature control is between 5-1 degrees Celsius; The water-cooled chiller can be equipped with a 1-ton locking force injection molding machine, and the temperature control is between 1-15 degrees; The water-cooled chiller can be equipped with a 12 ton locking force injection molding machine, and the temperature control is between 15-2 degrees Celsius; The matching of the air-cooled chiller is 8 times that of the water-cooled chiller, which means that the 1HP air-cooled chiller can be matched with a 64 ton mold locking force injection molding machine with temperature control at 5-1 degrees ）B: The second method: A 1HP water-cooled chiller can be equipped with an injection molding machine with a single injection volume of 1QZ, and the temperature of the injection molding machine can be controlled at 5-1 degrees The formula for injection quantity 1QZ=28.5g or above is the result summarized from the concept In addition to using the above formula, salespersons should consider the actual situation and choose a suitable chiller C: The matching of chiller and cooling tower, based on past practical experience, requires a 1.2-ton cooling tower for a 1HP chiller to remove the heat generated by the chiller.
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.

On the one hand, it can delay the sudden expansion after flow closure throttling, and transfer the damage position away from the sealing surface; On the other hand, it increases the throttling resistance, reduces the degree of pressure recovery, and weakens cavitation. Some design the valve seat hole in a stepped or wavy manner to increase resistance and weaken cavitation. This method is often used in introducing high-pressure valves into devices and improving old valves, and is also very effective. Changing the flow direction to improve the service life of the valve opening method, cavitation and erosion mainly act on the sealing surface, causing the root of the valve core and the sealing surface of the valve core seat to be quickly damaged; The flow closed type flows in the closed direction, and cavitation and erosion act below the sealing surface of the valve seat after throttling, protecting the sealing surface and the root of the valve core, and extending the service life.
