First of all, you should regularly vacuum the fabric sofa. It is best if you can do it once a week. The armrests, backrests and gaps of the sofa must also be taken into account. Of course, it can also be wiped with a towel, but when using a vacuum cleaner, do not use a suction brush.
Secondly, clean the sofa once a year with a cleaning agent, but the cleaning agent must be thoroughly washed off afterwards, otherwise it will be more susceptible to dirt. As for the choice of detergent, a special detergent containing antifouling agent can be selected. Some silicic acid sprays have a dust-proof effect and can be sprayed once a month.
The jacket of the fabric sofa can generally be cleaned. The elastic sleeve may be washed in a washing machine at home, and the cotton cloth or linen jacket may be requested by the laundry. When ironing the sheath, it should be noted that some elastic sheaths are easy to dry and hot. Even if you want to iron, you should consider the appearance of the fabric. If the jacket is cotton, it is not suitable for ironing.
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement (flow through the pump per rotation of the pump) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Although, hydrodynamic pumps are more frequent in day-to-day life. Hydrostatics pump which are of various types works on the principle of Pascal's law. It states that the increase in pressure at one point of the enclosed liquid in equilibrium of rest is transmitted equally to all other points of the liquid, unless the effect of gravity is neglected. There are different types of hydraulic pumps as below:
1. Gear Pumps
2. Piston Pumps
3. Vane Pumps
