Since the electric pump suction and pressure oil pump is any difference between electric motor pump plays an important role in engineering construction, machinery and equipment is one of the common. Electric pump in accordance with the current market can be divided into self-absorbing oil type and pressure electric pump two kinds of oil, for these two types of equipment, small for you to explain the difference. We use self-absorbing ability of self-absorbing strong electric pump, no external oil. The oil pressure electric pump powered by air pressure tank there, there are also pump up the oil itself with the cylinder to provide pressure oil pump inlet port. Lubrication, corrosion, cooling, washing and so on between the various components. Therefore, the electric pump lubricant also note the following aspects in the selection: appropriate viscosity, good viscosity-temperature characteristics. Viscosity is the first considerations in selecting lubricants portable electric pump, at the same operating pressure, the viscosity is too high, the movement of hydraulic components increase resistance heating accelerate the pump self-absorption capacity decreased line pressure drop and power loss increases, great; if the viscosity is too low, it will increase the volume loss of electric pumps, leaks in the elements increases, thin film and the sliding member, supporting ability. High pressure electric pump protection of the right way to protect the high pressure electric pump electric pump in place, then, can be cut using a fault, extending the use of life expectancy, the use of forward power and other benefits. High pressure electric pump to protect not only the performance of the protection after use, the correct way is a kind of protection in the use of high pressure electric pump. How protection is correct? Let's come together to see: 1, high pressure electric pump required before starting to turn the open air nuts, nut switch to turn the open air unloading position. 2, find the process of applying the motor temperature is too high, you should discontinue use. Wait for their own use to cool down. 3, high pressure electric pump is factory adjusted, usually no need to adjust again from scratch when you need to adjust the necessary means of pressure gauge. 4, high pressure electric pump hose briefly aging manual electric pump, often need to view, usually six months, repeatedly applying for three months, when viewing 87.5MPA pressure test and, if damaged, bulge, leak appearance, you can not use. 5, the bearings are usually cleaned once for six months, add grease devices.
