In fact, we all know that the product features and appearance of the reliance on the routine maintenance, the correct method can extend the useful life of hardware products, let us pay attention to the hardware products at home, a little care, there will be unexpected results.
Hardware is the soul of the entire inner door, including handles, locks, hinges, etc. They are small in size and have a significant role. The key to the service life of the inner door is the maintenance of the hardware.
Stainless steel handles and stainless steel other hardware can be wiped with brighteners, can add light.
The moving parts such as hinges, hanging wheels, and casters may lose their performance due to the adhesion of dust during long-term movement. One or two drops of oil can be kept smooth every half year or so.
When the lock cylinder is not flexible enough to rotate, a small amount of black powder may be scraped from the pencil lead and lightly blown into the lock hole. This is because the graphite component is a very good solid lubricant. Do not instill lubricating oil as this will make it easier to adhere to dust.
Special attention should be paid to the direction in which the handle is rotated and the dead force should be avoided. In particular, children should be educated. Do not hang on the doorknob and it is both prone to danger and may cause damage to the inner door.
During the busy season, what kind of necessary maintenance should be done for a winter submersible pump? In order to ensure normal use, do not drop the chain during irrigation and let Skywave Pumps develop a professional maintenance manual for your submersible pump:
1, check the wearing parts: submersible pump impeller, buckles, bushings, bearing seats and other consumables. First, the water pump should be partially removed to check if the wearing parts are intact. Do not use damaged and unqualified spare parts.
2. Replace the lubricating oil: separately open the oil hole screw in the seal chamber and the motor, release all the lubricating oil inside the sealed chamber and the motor, replace the new oil, and ensure that the lubricating system works normally.
3, remove the pump shell anti-rust: spring before use, should open the top-level pump casing, turn the impeller and then start after the start, to prevent parts from rust can not start properly and burn the motor. This maintenance is particularly important for water-filled motors.
4, to ensure that the seal: Agricultural submersible pumps on the seal requirements are very strict, in the replacement of sealed indoor lubricants, if the oily turbidity and high water content, you must replace the entire replacement or replace the seal box or seal ring to ensure its sealing Good performance.
5. Drying motor: Measure the insulation resistance of the winding and the shell of the submersible pump with a 500 megohmmeter. If the resistance is lower than 0.5 megohms, the motor moisture should be driven off. Drying methods include: external drying method, current drying method, and a combination of the two drying methods. The external drying method is to use an external heat source for treatment. Common measures include: (1) blowing hot air: using an electric heater blower (a small agricultural submersible pump can use a hair dryer) blowing hot air to achieve the purpose of drying; (2) bulb baking: In a closed box, several 200-watt bulbs are used for baking. Pay attention to the baking temperature can not be too high, should be controlled below 125 °C; (3) current drying: according to the impedance of the submersible pump and the size of the power supply, the motor three-phase windings in series or in parallel, and then access a variable resistor, adjust the amount of current About 60% of the rated current, the power is dry.
6, to ensure that the bearing lubrication: The water-filled submersible pump should check the replacement of the upper and lower end cap bearing housing skeleton oil seal and lithium grease. To ensure that the bearings work well under long-term lubrication conditions.
7, check the bearing: check the motor part of the upper and lower bearings, if it is found that the wear or clearance is too large, it is necessary to replace the new bearings in time, is strictly prohibited "sick" make do with. The inspection method is as follows: If the motor is running, a “click†sound is generated, and the cycle is proportional to the rotation speed, and it is laborious to turn the rotor by hand, which is a bit astringent or avulsed on the bearing raceway; if the bearing is intermittent The "click" sound, there is an indeterminate dead point when turning the rotor by hand, generally the ball frame is damaged, the inner ring is broken or the ball is broken. In the above situation, the bearing must be replaced to avoid further damage.
