The main factors that need to be considered when using a basic Peristaltic Pump include the compatibility of the liquid with the Peristaltic Pump Tubing used, the trade-off between flow rate and pulse rate(roller number), Each rotation will dose equal liquid volume which ensures the flow accuracy. and the roller number decides the pulsation of the liquid, if you need a low pulsation liquid delivery, pls choose the multiple rollers to pump head or work with the Pulsation damper.

The basic peristaltic pump with a simple display and easy knob control, which can meet the liquid constant transfer industrial cases. For example: food/cosmetic/beverage/checmical additive feeding. transfer the liquid from a big tank to the small tank, liquid circulation..etc.
Screw pump technology and reasonable selection of methods
Screw pump technology and reasonable selection of methods of selection of screw pump should follow the economic, reasonable and reliable principles. If the design selection of ill-considered, will give future use, management, maintenance trouble, so the selection of a practical production needs, reasonable and reliable screw pump can ensure the smooth production, but also reduce repair costs . Due to its variable conveying capacity, self-priming ability, reversible capability and ability to transport liquids containing solid particles, the screw pump is widely used in conveying water, wet sludge and flocculant solution in sewage treatment plants. First, the speed of the screw pump selection Screw pump flow and speed into a linear relationship, relative to the low-speed screw pump, screw pump with high speed can increase the flow and lift, but the power increased significantly, high speed accelerated the rotor and Stator wear, the screw will inevitably lead to failure, and high-speed screw rotor rotor length is very short, easy to wear, thus shortening the life of the screw pump. Through reducer or stepless speed regulation mechanism to reduce the speed, the exploration speed maintained at a reasonable range of three hundred revolutions per minute, and high-speed operation of the screw pump, the service life can be extended several times. Second, the quality of the screw pump Screw pumps on the market now more types, relatively speaking, imported screw pump design, excellent material, but the higher prices, some services are not in place, high parts prices, long ordering cycle , May affect the normal operation of production. Most of the domestic production of imported products imitation, product quality varies greatly in the choice of domestically produced products, considering its cost-effective time, the choice of low speed, long lead, transmission parts of good quality, long life rating of the product. Third, to ensure that debris does not enter the wet mud sludge mixed with solid impurities will screw the rubber material stator damage, so to ensure that debris does not enter the cavity of the pump is very important, many sewage treatment plant before the pump Installed a grinder, and some grille installation or filter, blocking debris into the screw pump, grill should be promptly salvaged to avoid clogging. Fourth, to avoid broken screw pump Never run in the case of broken material, once occurred, the rubber stator due to dry friction, instantaneous heat generated and burned, so the grinder intact, smooth grille is necessary for the normal operation of the screw pump One of the conditions, therefore, some screw pump is still installed in the pump body break down device, when there is a broken material, due to the self-priming screw pump has the characteristics of the cavity will produce a vacuum, the vacuum device will stop the screw pump Run. Fifth, to maintain a constant outlet pressure Screw pump is a positive displacement rotary pump, when the outlet end is blocked, the pressure will gradually increase, so that the pressure exceeds the predetermined value. At this time the motor load increased dramatically. Transmission machinery related parts load will exceed the design value, severe motor burn occurs, the transmission parts broken. In order to avoid damage to the screw pump, generally installed at the outlet of the screw pump bypass relief valve to stabilize the outlet pressure to maintain the normal operation of the pump.
