Electric valve is a device that drives the valve to open and close by electric motor. It is widely used in various industrial and civil fields, such as metallurgy, chemical industry, petroleum, natural gas, heating, ventilation and air conditioning, automatic control, etc. The following are some application scenarios of electric valves:
1. Fluid control in industrial production: electric valve can be used to control the flow, pressure and temperature of liquid, gas and steam to meet the needs of industrial production.
2. Oil and natural gas industry: electric valves can be used in oil and natural gas exploitation, processing, transmission and storage to control flow and pressure and ensure production safety and efficiency.
3. Chemical industry: electric valve can be used for fluid control in chemical production, such as acid-base solution, gas and liquid reactant control, to ensure the safety and efficiency of production.
4. Heating, ventilation and air conditioning system: the electric valve can be used to control the water flow, air flow and temperature in the heating, ventilation and air conditioning system to meet the requirements of the indoor environment.
5. Automatic control system: electric valve can be used with automatic control system to realize automatic control and adjustment of fluid flow, pressure, temperature and other parameters.
In short, electric valves are widely used in industrial and civil fields, which can improve production efficiency, ensure product quality and improve production safety.

This time, Qingdao Axis Precision Machinery Transmission Co., Ltd. and our analysis of the NSK bearing noise problem; tell you the three major reasons for NSK bearing noise and treatment. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
According to the bearing experience of Qingdao Axis for many years; the three major reasons for NSK bearing noise are: bearing dust; bearing has scars; bearing has a smooth agent is not appropriate; the following briefly and we talk about NSK bearing noise treatment.
1. NSK bearing dust treatment dust causes NSK bearing to announce noise: one can improve the cleaning method of the bearing; the bearing, shaft, seat hole and general fitting parts are all clean and clean before the equipment, and the foreign matter in the smoothing agent is eliminated. Three improved bearing seals, four to prevent the use of plastic materials that are impure or embedded with foreign bodies.
2, NSK bearings have scars to deal with scars caused by NSK bearings to declare noise: a device does not hit the bearing; the NSK bearing and the shaft assembled into the bearing housing to prevent the bearing installed oblique, two stocks to prevent bearing corrosion and Prevent shock oscillation during transportation, and use smooth grease with high viscosity.
3, NSK bearing has a smooth agent is not suitable for the treatment of smoothing agent is not appropriate to invoke NSK bearing to announce the noise: smoothing agent can be divided into three categories: a faulty smoothing agent, two smoothing agent short, three smoothing agent aging Induration. Choose a suitable smoothing agent; the smoothing agent should be increased by the amount of smoothness; the smoothing agent should be replaced by punctuality.
