Sand mining dredger maintenance often involves misconceptions. If you're unaware, it could impact the lifespan and service years of the dredger. To better protect your interests, the following detailed explanation will be provided by Qingzhou Yongsheng Environmental Sediment Removal Equipment Co., Ltd.

1. Blind selection of lubricants
The type of dredger determines the appropriate lubricant. In addition to ensuring quality, you should also consider the compression ratio and displacement to choose the lubricant best suited for your dredger.

2. Blind selection of machine accessories
Imported parts are not necessarily better than domestic ones; it's the ones that fit the machine that matter. Domestic parts are produced based on actual conditions and are more suitable for domestic sand mining ships, and the prices are also quite reasonable.

3. Blind disassembly of the engine thermostat
Disassembling the thermostat and draining the coolant only allows for a full circulation, without the ability to adjust the cooling intensity, leading to reduced engine power and accelerated wear.

Sand mining vessels are bound to encounter various issues during operation; avoid treating them blindly to prevent falling into误区 and affecting efficiency.
