It's cold in winter，The Spring Festival is approaching，The equipment that has been busy for a year is also going to have a holiday.，Take a break。For a year of hard work，To the owner“A broken stone adds gold.”，Work to force、Crushing and screening equipment of durable and anti-manufacturing clarite，Of course, it is worth taking good care of.。
So how to maintain the car correctly before the winter break?？How do we find out? “Small hidden danger”And carry out preventive treatment.，Avoid becoming in the future“Question”Does it affect the performance of the equipment?？How to clean your car，A series of tasks such as proper storage arrangement，It's not always easy to get a big piece of equipment like this.，Even experienced operators may miss something.。
But Uyghur fans don't have to be stressed.，Viv is very sweet.，It has been considered in advance for everyone.。Starting at the end of 2023，The Kelei service team of Wittgen China, together with the agent, has already taken action.，Carry out winter equipment inspection activities for customers with Kelei equipment nationwide。
At the construction site，The service engineers will check your car，Eliminate hidden dangers，According to the condition of the equipment, the operator will be given specific suggestions on the matters needing attention in the maintenance of the equipment in winter and on-site answers to the operation and use problems.，Help operators learn to operate and maintain the equipment better。
At the same time，In order to facilitate Uyghur fans to do a good job of self-examination of their equipment before the holidays.，According to the summary of on-site service professionals, Xiaowei listed the important maintenance items of Kelei mobile impact crushing equipment and mobile screening equipment one by one.，Convenient for everyone to implement one by one，Ensure that the equipment is under the test of low temperature, rain and snow.，It can also survive the winter.，Have a smooth holiday。Welcome to collect and use.。
Grease lubrication
Important system parts on the equipment shall be lubricated with grease first。For Ke Lei's counterattack.，Lubricating parts mainly include：Crushing rotor bearing and labyrinth bearing（Both sides）、Rotor drive belt tensioner bearing、Drive of the conveyor belt/Driven bearing、Iron picker bearing, etc.。
For Crewe screening equipment，Lubricating parts mainly include：Driving roller bearing for each conveyor belt、Driven roller bearing and vibrating bearing of screen box。
● Notice：
1.Winter butter with less viscosity is recommended；
2.Do not overfill with butter.，Please refer to the instruction manual；
3.After the butter is injected，Run the device briefly for 5 minutes，Allow the grease to reach every part of the bearings；
4.Special grease shall be used for vibration bearing of screen box.；
5.As shown in the figure below, the similar situation must be cleaned first.，Stop the machine after the new butter is put into operation。
Hydraulic system adjustment
Because of the low temperature in winter.，Brittleness enhancement of rubber seal，Toughness becomes poor，The hydraulic seal system becomes more sensitive at this point，So it needs to be adjusted.。
1、Clean the stem of all hydraulic cylinders with a soft cloth，Remove impurities；
2、Release the force on the hydraulic cylinder，Avoid loading the hydraulic cylinder for a long period of time，And that failure rate is reduce。
Break against mobile counterattack，The details are as follows：
1、Retract the hopper and lock it，Unload all hydraulic cylinders；
2、Fully lower the iron picker，Releasing iron picker hydraulic cylinder；
3、Fully lower the upper reaction plate cylinder，Unloading upper impact plate hydraulic cylinder；
4、Configure the material return system，The return conveying belt is kept in the return state.，And the head section is fully lowered on the support frame。
Electrical system adjustment
1、Disconnect the battery main switch，Prevent the battery from discharging outward；
2、Disconnect the main control box together with the connecting line from the electrical cabinet，Store together in a warm room；
3、Such asDevice stopped for too long（If more than 3 months），It is recommended to remove the battery，Keep in a warm and ventilated room，And regularly（Uch as monthly）Carry out indoor slow charging or start the engine and run charging every other month，Time at least 30 minutes；
4、Break against counterattack，Also remove the on-board remote control battery from the charger，Place in a warm place indoors together with the remote control transmitter。

Treatment of the engine
1、If the diesel oil-water separator is of water discharge type,，Be sure to drain water for treatment，Then manually pump the oil to the full level and bleed the air.；
2、The diesel tank shall be filled with winter diesel as much as possible.，Avoid condensation of water vapor inside the diesel tank；
3、Always make sure that the engine is filled with antifreeze suitable for the local ambient temperatures（The freezing point of the antifreeze is at least 5 degrees below the local minimum temperature.）。

Treatment of water pump spraying system（This article is aimed at mobile counterattack.）
1、If the diesel oil-water separator is of water discharge type,，Be sure to drain water for treatment，Then manually pump the oil to the full level and bleed the air.；
2、The diesel tank shall be filled with winter diesel as much as possible.，Avoid condensation of water vapor inside the diesel tank；
3、Always make sure that the engine is filled with antifreeze suitable for the local ambient temperatures（The freezing point of the antifreeze is at least 5 degrees below the local minimum temperature.）。
Adjust the conveyor belt to the folded state（This clause refers to mobile screening machine.）
Taking into account possible weather and safety factors during the winter break，The primary conveyor belt needs to be adjusted from an operational unfolded state to a stored folded state。Because the conveying belt is supported and fixed by a lock pin,，It not only takes into account the safety but also unloads the pressure of the hydraulic cylinder.。
1. The conveyor belts on both sides are adjusted to the folded state and are supported and locked；
2. The oversize conveying belt rotates back to the longitudinal direction of the equipment，Lower onto the transport support and lock；
3. Lower the screen box properly and lock it mechanically；
4. Retract the lighting pole；
5. It is recommended that the equipment be fixed by hydraulic support for the hopper.。
We need to remind you that， If The equipment has a long winter break.，Even more than six months.，Then in addition to the short winter break treatment described above,，The following operations are also required：
1、Remove the monitor，Store indoors in a warm environment；
2、Add special engine oil, etc.；
3、Conveying belt of the equipment（Uch as a discharge belt）And a drive belt（Rotor drive belt, etc.）Relax moderately to prevent contraction and laceration.。
Wei has something to say
Due to limited space，Xiaowei will launch a separate issue specifically for Kelei equipment.，Introduction to how to clean the equipment before winter break，Please continue to pay attention to Wittgen's official account in China.。
Winter maintenance and cleaning strategy for Kelei equipment，If Uyghur fans still don't know something.，You can contact Kelei's service team for consultation.，It can also be used during the inspection of the service team，Use the opportunity of on-site communication to answer questions and solve doubts。In addition，Ours《Dimensional classroom》The operation of Kelei equipment will also be carried out irregularly.、Maintenance and other courses，Partners who want to learn，Please pay attention to the relevant course information released by our official account.。
