Using reliable quality motor,380V or 220V or direct current machine is optional.

Features

1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive

2.Power off seal,no leakage,with security delivery device,simple maintance

3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods.

4.The flow can be controlled via adjusting the length of stroke or the motor frequency.

5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.

Purpose

Widely used in petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding,light industry, agriculture, national defense department and etc.

Q: How about the depreciation of vacuum pumps?: (five) electronic equipment, for 3 years.The depreciation period of a vacuum pump can be calculated for 5 years. The expected residual rate is generally 5%, or it can be estimated by itself.

Q: What is the dry running protector of screw pump? What's the principle and function? Thank you: Principles are generally temperature sensing, such as: when the screw pump by air, the stator and rotor will be heated due to friction,

Q: How many millimeters is the diameter of the water outlet of the four inch pump?: If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.

Q: What is the liquid pump? What are their categories? What are their strengths and weaknesses?: The liquid pump can be filled with oil, water and chemical medium. The gas drive range of the liquid pump is 1 to 10bar (14.5-145psi). The bottom piston is controlled by a two position four pass pilot valve.

Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.

Q: What are the problems that should be paid attention to when using vacuum pumps?: (8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.

Q: The working principle of magnetic pump: Working principle of magnetic pumpN of the magnet (n is even) arranged according to the laws in the magnetic clutch assembly inside and outside the magnetic rotor, the magnet part consisting of magnetic coupling system. When the inside and outside the two poles in different relative displacements, two poles between the angle phi = 0, the lowest energy magnetic system; when rotates to the relative displacement is two poles, pole angle between phi = 2 pi /n, the magnetic system of magnetic energy. Remove the external force, due to the magnetic system of magnetic poles repel each other, magnetic magnet will return to the lowest energy state. So magnets in motion, driven by the magnetic rotor.

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: Centrifugal pump, and is a very common method of centrifugal pump, flow with the head (or pressure) increases, off a small valve resistance increases, the pump head should be increased, then the flow decreased, whereas open valve flow increase

Q: How to maintain and repair the booster pump of pipeline pump?: I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.

Q: How to calculate the motor power of metering pump?: Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
