1, stainless steel gear pump features. Stainless steel gear pump gear, shaft, pump body, safety valve, shaft seal and other components, the gear heat treated by a higher hardness and strength, together with the shaft installed in the interchangeable sleeve operation. The lubrication of all parts in the pump is automatically achieved by the use of conveying medium while the pump is in operation. The pump has a well-designed drain and return tank, the gear in the work to withstand the torque of the smallest, so the bearing load, wear small, high pump efficiency. The pump has a safety valve as overload protection. The full back pressure of the safety valve is 1.5 times of the rated discharge pressure of the pump. It can also be adjusted according to the actual needs within the allowable discharge pressure range. But pay attention to the safety valve can not do long-term work of the valve, if necessary, can be installed separately in the pipeline. 2, the scope of application of stainless steel gear pump: gear pump is suitable for conveying solid particles and fibers, corrosive, the temperature is not higher than 120 ℃, the viscosity of 5 × 10 -6 × 10 -3 m 2 / s (5 ~ 1500cst) or other liquids of a similar nature as lubricating oils. Stainless steel gear pump pump body and both sides of the cover for direct contact with the hard seal, if the contact surface flatness does not meet the requirements, the pump easy to inhale the air in the work; Similarly, between the pump cover and gland But also for direct contact, the air is also easy to invade; if the gland is a plastic product, because of its damage or temperature of the stainless steel gear pump pump body and both sides of the cover for direct contact with the hard seal, if the contact surface flatness In the same way, the pump is also in direct contact with the gland and the air is also easy to invade. If the gland is made of plastic, due to its damage or deformation due to temperature changes, Will also make the seal lax and into the air. When the gear pump or the flatness of the pump cover less than the required requirements, can be used in the flat sand with the "8" shaped back and forth grinding line, or grind on a flat grinder, flatness does not exceed 5μm, and the need to ensure that the plane and the hole perpendicularity requirements; for the pump cover and gland at the leak, can be coated with epoxy adhesive sealing. The shaft is generally used to seal the shaft seal. If the locking lip spring off, or the oil seal installed, or its lips were injured, aging, will make the back end of the seal often in negative pressure and inhale the air, the general can replace the new seal to be resolved. The fuel tank is not enough fuel, or suction nozzle is not inserted below the oil surface, the pump will inhale the air, this time should be to the tank to replenish the fluid to the oil standard line; if the return pipe mouth exposed oil, and sometimes because of the system Negative pressure within the instantaneous air back into the system, so return pipe mouth generally should be inserted below the oil level. Gear pump installation location is too high from the oil surface, especially in the pump speed is reduced, because the pump can not guarantee the necessary degree of vacuum caused by the suction caused by insufficient suction air. Water ring vacuum pump is a rotary vacuum pump, circulating water vacuum pump is widely used in evaporative distillation, crystallization, filtration, vacuum, sublimation and other operations, low temperature cooling circulating water vacuum pump is a vacuum pump and low temperature cooling pump combination. Which can be evacuated, but also to provide low-temperature cooling circulating water, vacuum distillation and decompression enrichment is a good auxiliary equipment, especially adapted with a rotary evaporator, not only reduces the use of space, but also reduces the degree of vacuum, saving water, Widely equipped by modern laboratories. Jet vacuum pump is the use of a higher working fluid to transport another fluid. By and jet pump (or injector) combination, relying on the injection device, resulting in a vacuum nozzle to achieve suction. ã€Purchase】 Fire Pump, Spray Pump, Sewage Pump ã€Purchase】 Bearing Parts ã€Purchase】 Air Lock Valve ã€Purchase】 Signal Amplifier ã€Purchase】 Valve ã€Purchase】 Centrifugal Pump ã€Purchase】 Vertical Multistage Pump ã€Purchase】 Cylinder 〠Procurement】 Speed ​​Control Motor Previous: Ground rail the main purpose and advantages Next: Screw pump disassembly and assembly
