The circulating water pump circulating water pump circulating pump on the basis of the multi-use vacuum pump circulating water, according to a small laboratory area characteristics, with reference to Japan desktop pump, disposable shell molding, reduced size and improvement made with a small size, light weight , good looks and features dual table, stud pumping, circulating water vacuum pump four tables and four-tap the same double-sided, multi-use vacuum pump, even in the visual presentation of teachers, students or on any side of startup, shutdown. The circulating water pump body using double tap, is equipped with two vacuum table can be used alone or used in parallel. Host a stainless steel movement and anti-corrosion material movement in two models manufacturing. The corrosion-resistant, non-polluting, low noise, easy to move, but also according to the user needs to install vacuum regulator valve. The same time, there are four students conduct chemical experiments, narrow space of experimentation. Recycled water with a vacuum pump the image circulating water vacuum pump was originally used as a self-priming pump, and then gradually for many of the industrial sector of the petroleum, chemical, machinery, mining, light industry, medicine and food. Circulating water pump in many industrial production process, such as vacuum filtration, vacuum diversion vacuum feed and evaporated in vacuo, and concentrated in vacuo to a resurgence of vacuum and vacuum degassing, etc., the pump to obtain a wide range of applications. Water ring pump vacuum rapid development of application technology in the rough vacuum to obtain the attention. Water ring pump gas compression is isothermal, it can be exhausted, flammable, explosive gas, addition to pumping gas in addition to dust, moisture content, therefore, the circulating water applications increasing number. The pump body equipped with a suitable amount of water as a working fluid. When the impeller is rotated in the clockwise direction in the figure, the water by the impeller is thrown around, due to the effect of centrifugal force, the water forms a decision in the shape of the pump chamber approximates the thickness of the closure ring. The inner surface of the lower portion of the water ring happens to the impeller wheel hub tangent to the inner surface of the upper portion of the water ring coincides with the blade tip (actually blades in the ring of water has given the depth of insertion). Form a crescent space between the impeller hub and the water ring, and the space is the impeller divided into, and the same number of vanes several small cavity. If the circulating water pump to the lower portion of the impeller zero starting point, then the impeller at 180 degrees before the rotation, a small cavity size from small to big, and communicating with the end surface of the intake port, the gas is drawn, when the end of the inspiratory The small chamber is isolated from the intake port; when the impeller continues to rotate, the small chamber, from large to small, so that the gas is compressed; when the small chamber with the exhaust port, the gas is discharged to the outside of the pump. Technical parameters: Model SHZ-D (III) circulating water pump power: 180W Flow 60L/min working power 220V/50Hz lift 8m, anti-corrosion of the body material, the maximum degree of vacuum 0.098Mpa, single head exhaust volume of circulating water pump 10L / min, exhaust head 2 storage tank volume 15L, the appearance of size 400 * 280 * 420 Weight 15kg. SHZ-CA circulating water pumps power: 370W Flow 80L/min, Power 220V/50Hz, lift 12m, anti-corrosion of the body material, the maximum degree of vacuum 0.098Mpa, single-head exhaust volume 10L/min, suction head 3, Reserve water tank capacity 50L, the appearance of size 450 * 340 * 870, the whole machine weighs 37kg. SHZ-95B circulating water with a vacuum pump power: 370W, the flow 80L/min, work power 220V/50Hz, lift 12m, Body Material Stainless Steel, maximum vacuum 0.098Mpa, single head suction capacity 10L/min, pumping head of 5 Reserve water tank capacity 50L, the appearance of size 450 * 340 * 840, the whole machine weighs 35kg. SHZ-DIII (4 - size head 8m, anti-corrosion of the body material, the maximum degree of vacuum 0.098Mpa, single-head suction capacity 10L/min pumping pumping) circulating water pump power: 370W, flow 60L/min, working power 220V/50Hz, The first four of reservoir water tank capacity 15L appearance of size 400 * 280 * 420, the whole machine weighs 15kg. Stainless steel pump, double table double-tap, with 2L, 5L evaporator / reactor stainless steel pump, five taps of the single-table, equipped with 10L, 20,50 L evaporator / reactor Desktop SHZ-D (III) vacuum pump the maximum degree of vacuum : negative 0.098Mpa, better vacuum-degree water at 4 ° C to 10 ℃. The (Dual table double tap) Vertical SHZ-95B vacuum pump vacuum degree: negative 0.098Mpa water at 4 ℃ to 10 ℃ vacuum degree better. (Single table of five tap) the vertical the SHZ-CA vacuum pump vacuum degree: negative 0.098Mpa, better vacuum degree water at 4 ° C to 10 ℃. (Table V single tap) This product is designed with a rotary evaporator, double glass reaction kettle, vacuum drying oven, vacuum filters, filtration bottles, rotary film evaporator, multi-purpose reactor, vacuum thin film concentrator products is one of the ideal laboratory indispensable.
