Home lift oil pump solenoid valves

Normally on the home lift oil pump we have three solenoid valves to control the platform get down: fast valve, slow valve and close valve. Fast valve and slow valve will let the platform get down to floors very smoothly, speed will slowly become zero. Close valve is to ensure the oil will not drain back to oil tank when cabin stay at certain floor, so cabin will stay at certain floor for long time and without changing the position. 

To adjust getting down speed, you can adjust slow valve and fast valve by turn the handles next them. But we already adjust them before shipping. So better not adjust it anymore.

cargo lift with enclosure finally installed

 finally this cargo lift is installed by my customer. Because this lift is used outdoors, so I make enclosure for him to cover the lift body. I use aluminum board and 4mm thickness so the cover will be more strong from outlook. And such lift have 3 landing doors: only when cabin at certain floor then the landing door at this floor can be opened. also if any door is open the lift will not rise or get down.

Test home lift before you connect wires

 After you assemble my home lift, you can firstly test the lift by click buttons in control box. You can test the motor firstly without connect wires to calling buttons and limit switches.

You click both com and up buttons, the platform will rise up. And you click both com and down buttons, the platform will get down.

You may find the rising or getting down speed is slow, it is normal situation. because to test lift, the speed cannot be so fast.

 normally for double sets of columns guide rail lift, its doors cannot be 90 degree. That mean if you enter the lift from one direction, but you cannot turn 90 degree and exit from the platform. Now, according to my customer special requirement, I design the lift that can realize such function. I make two doors on this lift and they are 90 degree direction.

For home lifts, how the aluminum alloy enclosure connected.

because we will ship the enclosure without installation, so these videos are necessary for buyers to know in advance.

The L shape connector is used to fix on walls.

 Some times we use silent oil pump for our customers. Silent oil pump has below advantages:

not issue noisy, the sound it issues even lower we normally speaking.

if you choose silent pump, the inverter is needed inside control box. good thing is that inverter make lift running very smooth, it can accelerate speed slowly also it can let speed get down slowly. This will be good for lift structure.

because motor is inside oil tank, and not expose outside so the motor will be not easy to damage.

but there are also some disadvantages:

cost is higher than normal oil pump.

it is better put outside of the lift body for easy access to maintenance.

max. can be 5.5kw. if over 5.5kw the motor will be not stable enough.

sometimes during transportation some air blocked inside, and when you first start it, it may not pump oil.

For the 4th disadvantage point it is also easy to solve, attached is the video I made for solve this problem. Don't forget to open script when you watch this video.
