The pump action is exerted on the cooling fluid pressure

Whether it is a good assistant or combustion forklifts are electric forklift warehouse jobs , as companies  increasingly popular warehouse forklifts, so many handling operations to a forklift, an increase in the number of forklifts , forklift improper use can also lead to "sick" Therefore, to understand the performance of the forklift , will "remedy ." Today, I will introduce the forklift water cooling system.
Forklift water cooling system is  composed of a fan , sub- pipes, thermostat, blinds, water jacket , radiator , water Straddle stackers pump coolant temperature gauge and other components. The most commonly used in the market , the most common is the forced circulation type water cooling system. If the engine is equipped with a cooling intensity adjustment device , and blinds , fans and other components thermostat , the engine in cold ambient temperatures can quickly reach optimum operating temperature Hand fixed lift table and prevent excessive cooling .
1 Thermostat
 The role of the thermostat is to  blame variable coolant circulation routes and traffic, you can automatically adjust the cooling intensity , so that the coolant temperature is kept at 80 ° C-90 ° C, the thermostat is generally installed in the cylinder head or pump outlet into the inner pipe .
 2 , the pump
 The pump action is exerted on the cooling fluid pressure , cooling fluid circulation .
3 , fans
Fans role is to facilitate ventilation of the radiator. Usually the fan is mounted behind the radiator , to better facilitate ventilation. When the fan is rotated to generate the suction air , the air flows along the axial direction , from front to back airflow through the radiator , so that cooling air flow through the radiator to accelerate cooling fluid for cooling the engine acts .

Left interactive twist SZ

For shares in double abseil rope around the core and then twisted around double rope, good flexibility; but manufacturing is more complex, and the wire is too thin, easy to wear, it is rarely used. Rope wound around and along the cross direction around the two kinds. Wire twisted into stocks and shares around the twisted rope around the same who said to shun around. Shun contact between the wire rope around better, manual stacker  is also good, long life, but there is a tendency to twist loose, should not be used to enhance the free end of the rope hanging heavy objects can be used as a rigid guide rails for heavy line when upgrading a rope or leash. Wire twisted into stocks and shares around the twisted rope around the wound to the contrary, said post. The rope is not easy to reverse the cross around loose, widely used in the lifting operation.
a right-interactive twist ZS: Right rope twist, twist stranding shares left direction of stocks within the wire twist in the opposite direction, said interactive twist
b Left interactive twist SZ: rope left twist, twist the right stocks
c Right in the same direction twist ZZ: Right rope twist, twist the right stocks
d left twisting in the same direction: left rope twist, twist left stocks
e the right mix twist: the right rope twist, twist left some stocks, some stocks right lay
f Left Mixed twist: rope twist left, right lay some stocks, some stocks left twist
Status classification
Each wire can also be hand pallet trucks in the state of contact between the wires into point contact, line contact or surface contact with three kinds.
① point contact wire rope: Shares in wire diameters are the same. Uniform force to the wire, each wire after winding around the helix angle is substantially equal to, but away from the winding range, so that the inner and outer wires cross each point contact state.
② line contact wire rope: Shares wire twist away the layers are equal, the inner and outer wires touch each other in a spiral line, line contact state. Performance than the rope line contact point contact has greatly improved, so widely used.
③ surface contact wire: a strand surface contact, the outer layer made ​​of profiled steel, smooth surface, good wear resistance, with the same diameter as compared to other types of wire rope, greater tensile strength and can withstand lateral pressure However, poor flexibility, process more complex, high manufacturing costs, commonly used for carrying cable, such as cable cranes and aerial cableway funicular.
