NYP high viscosity pump maintenance process

NYP high viscosity pump has good performance, to meet the needs of different industries, there may be some faults and defects in use, the group should pay attention to the daily maintenance work in the usual use, the need to pay attention to the maintenance mode A lot, in accordance with certain problems and principles of good control, to fully demonstrate the value of certain functions and life expectancy. The following describes the NYP high viscosity pump in the maintenance of the Notes: NYP high viscosity pump in daily use, pay attention to save The electric pump should be placed in dry, clean and non-corrosive gas environment. Save each part and replace the same parts, the demolition of the gear pump, you should save each part, pay special attention to the explosion-proof parts of the explosion-proof surface can not damage the hairline, including insulation pads and casing, if damaged, Must be replaced on the same new parts, shall not be used below the performance of alternative raw materials or parts of the original specifications do not match, all parts should be assembled according to the original location, can not be omitted. In recent years, surface coating technology in China's equipment maintenance has been widely used for a variety of materials, parts and equipment repair. Its working principle is to add molybdenum disulfide, metal powder, ceramic powder and fiber and other special filler adhesive, directly applied to the surface of materials or parts, so that it has a wear-resistant, corrosion and other functions, mainly for surface strengthening and repair . Its process is simple, convenient and flexible, safe and reliable, does not require specialized equipment, just a good glue coated on the surface of the cleaned parts to be cured after curing can often operate at room temperature, will not make the parts Produce thermal equivalent effect and deformation. NYP high viscosity pump coating process although relatively simple, but the actual construction requirements are quite strict, just choose a good adhesive, not necessarily able to obtain high viscosity strength. It is necessary to select the right adhesive, but also strictly in accordance with the correct process of adhesive coating the right adhesive, but also strictly in accordance with the correct process method line viscosity coating in order to obtain a satisfactory coating effect. NYP high-viscosity pump often fat, electric drum pump for high-speed operation, easy to volatile grease, so the bearing lubrication must be kept clean, and pay attention to change. NYP high-viscosity pump often check and repair, electric drum pump should always check and repair, to check the power cord: internal wiring, plugs, switches are good, the insulation resistance is normal, brush tailstock is loose, commutator and brush Good contact, armature-level expansion stator winding is a proper way to break the phenomenon of bearing and rotating parts are damaged and so on. NYP High Viscosity Pump CAUTION Insulation resistance, long term stand-by or electric pumped pump used in wet environments must be measured with a 500-volt megohmmeter winding insulation before use. If the insulation resistance between the winding and the motor housing is less than 7 megohms, the winding must be dried. NYP high viscosity pump in use to ensure that in the actual use of performance have a good role and value, according to the correct way and principle of control and production, get a good way to maintain and extend the service life.

STEP Inverter

AS380 series elevator integrated drive controller is the new generation of state-of-the-art elevator-specific control and drive device. With full consideration of the safety & reliability of elevator;inherent characteristic of elevator operation and specific feature of potential energy load for elevator, AS380 series elevator integrated drive controller adopted advanced technology of frequency control of motor speed and intelligent elevator control as well as the integration of control & drive of elevator to make the further improvement of the product performance, easy-to-use property and cost efficiency.

Main features

a) Prefect integration of control and drive of elevator. The whole device features compact structure and small size, fewer connections, which is characterized as high reliability and easy-to-use property and cost-efficiency.

b) Double 32-bit embedded microprocessor jointly finish the elevator operation and motor drive control

c) Redundant safety design , double safety protection for control processor and drive processor to achieve the maximum safety guarantee for elevator travel

d) The design requirements of anti-interference capacity go beyond the highest standard in the industrial design requirement. e) All CAN bus communication make the whole system connected easily, data transmitted strongly, and more reliable.

f) The adoption of the advanced direct landing technology make elevator running more efficiently

g) The advanced multifunctional elevator operation mode can fully meet various needs of customers`

h) Advanced group control feature. Not only compatible with the traditional group control mode of up to 8 units, but also support the new group control of destination floor distribution.

i) The adoption of advanced vector control technology can make the motor speed adjusted well for the realization of the best elevator comfort.

j) Adapt to both synchronous motor and asynchronous motor.

k) Newly-developed none-load sensor-activated compensation technology provides excellent starting comfort to elevator even if no counterweight is installed.

l) To adopt incremental ABZ encoder to realize the synchronized control of motors. To adopt the none-load sensor-activated compensation technology to achieve the excellent start-up comfort.

m) New PWM dead band compensation technology can effectively reduce the motor noise and loss of machine.

n) Dynamic PWM carrier modulation technology can effectively reduce the motor noise.

o) Auto-tuning phase of synchronous motor without encoder

p) Asynchronous motor is not required for motor parameter acquisition process once the motor parameter is set correctly. The convenient static motor parameter acquisition process is available If is impossible to acquire the exact motor parameter on site. So there is no need to hoist the car and etc in this way.

q) The hardware is the 6th generation of module with the junction temperature resistance up to 175℃. Low loss for switch and connection to ensure the long use life.
