◊ Application

RS Series vacuum pump is compact, light and attractive in design. It uses the big starting torque and is specially designed for low temperature environment. It is guaranteed start normally in winter’s low temperature. It is applicable to vacuum packaging, vacuum freez

This kind of pump is widely used in food packaging, scientific research, medical treatment, electronics, chemicals, medicine and laboratory of universities and colleges.

ing, automobile reparation, gas analysis, medicine mechanism, printing mechanism and other vacuum evacuations.

◊ Technical data

Q: Know flow and lift how to calculate the pump power?: The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q: Why should the pump be closed when the centrifugal pump is started?: Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.

Q: What is a gear pump for?: Oil pump casing wearIt is mainly the wear of the floating sleeve hole (the normal clearance between the gear shaft and shaft sleeve is 0.09~0.175mm, and the maximum shall not exceed 0.20mm). The gear work is affected by the pressure oil, the gear tip is close to the oil pump casing, and the low pressure chamber part of the pump body is worn. Another kind of wear is the circumferential wear of the work surface in the shell. This kind of wear is mainly caused by the addition of oil which is not clear, so the oil without impurities is necessary.

Q: The water tank of the fish tank does not air out and only has the water outlet: The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.

Q: Does vacuum pump oil belong to dangerous goods?: Absolutely not. We often send oil by express or by freight. There are no problems at all. Don't be afraid, don't burn, explode

Q: The main factors affecting the performance of centrifugal pumps: The specific speed is deduced by the law of hydraulic similarity, and the similarity between the hydraulic characteristics of centrifugal pumps is similar. In centrifugal pumps, the specific speed is often interpreted as: the pump works at the highest efficiency, generating a lift of LM, a flow rate of 0.075m, and the power consumed by the /s at 0. 735kW

Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?: Start the pump. Water pressure depends on how large you buy the pump, generally small, mostly 10-15 meters hydraulic pressure, about 200 of the price.

Q: How many square cables does the submersible pump for 7.5KW need?: 7.5KW's submersible pump requires 2.5 square aluminum cables.Calculate the current value of submersible pump first:

Q: What's the difference between a concrete pump and a concrete pump truck?: Concrete pump is a pumping machine used in the field, while the concrete pump truck is a truck mounted pump.

Q: Types and differences of pumps: Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
