◊ 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

◊ Products' picture

Q: The distance from the pump button to the ground: After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.

Q: What does "efficiency" mean in a water pump catalog?: General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa

Q: Excuse me, what is the water pump from the lotus root?: The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection

Q: How many kilograms of water pump are there in the automatic washing machine on the market?: Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!

Q: What is the pump delivery? What's the difference between years and years?: Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n

Q: What is the pumping property of concrete?: Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.

Q: How many square cables does the submersible pump for 7.5KW need?: I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).

Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why: First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.

Q: What is a vacuum pump for?: In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same

Q: Why is the submersible pump tripped on an electrical switch?There is no electrical leakage protection, directly connected to the circuit breaker, and when the switch on, the circuit breaker jumpedI checked the line is good, the pump did not break down, is not the water pump?: Calculate or refer to the water pump nameplate that the normal operating current, according to this data exchange switch.2) with 500V shaking table, measuring the cable, motor insulation is in line with the requirements
